As with their hands to screw pile

Installation Screw the foundation - a decision that is taken by the developer on the basis of precise calculations and rationale. In front of him waiting for a lot of work, and most importantly, what you should take care in the first place - in order to prevent errors in the regeneration of the base for future construction. Cost of installation of the pile and the desire to fulfill the basic processes of building the house himself forced to set serious goals.

Properly mount the screw foundation - it means to observe all the specified parameters: horizontal and vertical levels, the distance between the piles, the allowable deviation from the linear dimensions and so on.. And if the problem is with the horizontal level ensuring solved or cutting capacity, then how to ensure compliance with the specified distances, we will discuss in this article.

Installation of the screw pile foundation with their own hands - a laborious task. It requires error-free calculations, the availability of special equipment and participation of at least two people - the cost of failure here may be too high.

Screw piles: installation

Installation of piles without involving specialized construction equipment in two ways: manual (for screwing used long metal levers) and mechanized (implies the use of mechanical adapted driven by the compact engine).

The simplest means for screwing the well head assembly is that fits over the trunk of the product and is fixed there by means of a pin inserted into the access ports.

By the end walls are welded clips, into which the levers to transmit torque to the pile. In principle, the screw pile is possible by inserting a crowbar to lever itself into technological holes support.

But the uneven distribution of the load in such a case, you can pay a high price: it will lead to the fact that the tip is deformed before it reaches the screw solid soil layers.

As the arms can be used for screwing two metal thick-walled pipe section (wall thickness should be not less than 5 mm). arm length is 2-3 meters.

Hotmotor (User FORUMHOUSE):

In the process hole put in the floor of the truck Mercedes, it put two two-meter tubes and "on time" pyzhilis. After each rotation checking levels. One revolution - 10 cm down.

Installation of piles:sequence

If you do not want to make any mistakes during the self-tightening, the correct positioning of supports guarantees you 90% success rate.

Installation of the screw-pile foundation is different in that the layout of the future location of the supports more correct not to start work, and in the process of their implementation. This will allow to arrange them in strict accordance with the size of the future house, baths or any other buildings.

The fact that pre-marking the foundation is not always possible to put piles in strict accordance with each other. Therefore, the layout must be made, since the positioning of a corner point of the future buildings.

To visualize the scheme of pile foundation dimensions 6 * 6 meters.

How to install piles numbered in the diagram. The first is screwed №1, located in the upper right corner of the circuit.

Under №1, in a prescribed place by a spade drill or dig a pit with a diameter approximately equal to the pile diameter the blade. The depth of the pit should be 20-30 cm. Some do more, but a special reason to do so. On the contrary, too much depth of the pit interferes with the right to maintain the distance between the piles.

Hotmotor:

First recess garden brown (50-80 cm), then set the pile. I baits, each controlled level. Further screwed together.

First screw the easiest. During operation, enough to control the level of vertical piles (for this purpose it is best to use a magnetic layer). If you are three, one man using level monitors the position of the pile in the space, and the other two - the support is screwed into the ground.

Twist together very hard. Therefore, the most difficult work better to attract 4 people. The pile is screwed into the ground to a depth greater than the depth of frost penetration. Her tip is to enter into solid layers of soil a few turns.

The pile should be screwed into the ground to a halt. Only such an approach can ensure that it will not be pushed out of the ground by the forces of frost heaving.

SVF-Master (User FORUMHOUSE):

4 people pile twist, using leverage of 2.5 meters. Twist all the way until his feet into the ground will not dig. Understanding this point comes with experience. The blade must be screwed below freezing. For vertical level it makes sense to keep an eye at the initial stage. After the pile will include about 80 cm, align it will be very difficult.

After the first pile installation is finished, you can begin to support markup № 2. Reference points in this case are the walls of the size and the distance between the axes of the piles. Assume that the distance between the axes, we still refer to 5850 (which can be calculated from the length of the wall and the size of end walls on stilts). The plane of the wall runs parallel to some other object (parallel to the fence, etc.). In this plane, we are holding a straight line and note this distance. This will be the location axis of the second pile.

There also digging a shallow pit, inserted pile, check its vertical level, and measure the distance between the axes of two supports. If there is no deviation, we begin to be screwed. Otherwise, the pile will have to align. №2 if necessary by a few centimeters to push №1, then its top should be rejected in the opposite direction of number 1. Thereafter № 2 to 2-3 turns necessary to screw into the soil. Then, putting the support vertically, it should again check the spacing. If all the dimensions are the same, №2 can be screwed until it stops. If not, repeat these operations until then, until a satisfactory result.

The pile is always tilted in the opposite direction from that in which it is necessary to push screwed support.

Odoff (User FORUMHOUSE):

Screwing in 2-3 passes (one turns, the other holds vertically), and then looked at roulette, find out where to shift. Then, spinning at an angle in the withdrawn bottom dot. Placed vertically (in rotation), and viewed on a roulette again.

Location № pile 3 is defined, on the basis of two linear dimensions: diagonal future house box (8273.15 cm) and the distance between angled piles (5850 cm). The marking is done by means of two tape measures (№3 will be installed at the intersection of the set of values ​​in their measurement bandwidth).

№ № 3 and 4 are set similarly to № 2. After the corner posts are screwed into the ground, on their outer perimeter should pull the rope construction. Rope simplify the layout and installation of the remaining piles to be screwed in the following order: first, mounted bearings, located on the outer perimeter of the walls, and then - the internal.

After all the piles are screwed, they should be cut off. Pruning is done grinder on marked horizontal level.

Odoff:

Trimming of the laser - a sweet deal. Conveniently turned clamp marking to hang from the top of the cut, then the schedule carefully grinder, then move the clip above and cut pile.

Incomplete screwed to equalize all the poles on the horizontal level (without subsequent trimming) is invalid violation construction technology.

Clipped piles filled with cement-sand mortar. After that it can be welded to the end walls and attempting to install piping.

Pile should be filled with cement mortar, but not concrete. Crushed poorly compacted, and after pouring of concrete within the cavity may be formed with air.

Slurry does screw piles structure firmer. The main purpose of the filling solution support is to block the access of oxygen in its internal cavity.

Curler screw piles

As we have said, the manual way of screwing requires great physical effort, which not everyone can tolerate. If you are not a miracle-hero, ready to pay for the foundation of the high price of health, think about mechanization. Mechanization also necessary if the pile is screwed into the vicinity of a land object (near the fence etc). In this case, it screwed with long levers is much more difficult.

Today you can buy a ready-made device (albeit at very high prices), designed for the mechanization of the process (svaekrut).

But such a device for screwing piles are expensive, and it is advisable to buy it, just doing the provision of services for the construction of pile foundations. The cost of installation of screw piles over time will pay for the purchase of this adjust. For work on its own site can build improvised device having a powerful drive of the drill or benzobura (augers).

If you are not ready for independent manufacturing unit and want to order the installation of screw pilesPrice and quality must be proportionate. You can look for the performer to our exchange, not only residents of Moscow, but also in many other regions.

Equipment that can be made with your own hands, is made up of several components:

• The power unit (drill, augers, etc...);
• Lowering mechanical reducer;
• Adapter: a power unit to the gearbox and gearbox to the pile:
• Supporting arm.

Here are adapted for tightening the screw piles looks assembly.

Consider all the components in more detail.

power plant

As the power unit can use motor or benzobur powerful electric drill. Using an electric drill is the most affordable option of all the above, but it must meet certain characteristics:

• There shall be a speed adjustment;
• minimum drive power - 2000 W;
• A reverse.

singer777 (FORUMHOUSE User):

The device - Rebir (brand electric drill) 2 kW. Frequency of revolutions during operation through reduction gearing - 300 rev / min.

Augers or motors used to spin, must also have the specified power.

reducer

The most common type of gear used to screw piles, is an ordinary wrench - wheel wrench with torque amplifier (with UKM). It is designed for screwing the wheels on heavy trucks. In use this device called the "meat grinder."

About the reliability of these devices goes a lot of controversy. But, relying on the user experience Forumhouse, we can say that a properly selected wrench, regular lubrication and in the absence of overload will help you tighten or one ten piles.

Should choose the reducer according to several parameters. The key role played by the torque that is capable to create on the output shaft. Manual machines for screwing piles produced in such a way that the operating torque is not less than 4700 Nm. Consequently, the performance of the wrench must comply with this parameter.

singer777:

The moment should be over 4500 Nm. They are reinforced grinder, which last longer and cost a little more expensive.

The larger gear ratio, the easier it will be to work with such gear. When selecting a device to be guided by the gear ratio - 1:60 or more.

singer777:

Characteristics wrench used: gear ratio - 1:64, maximum torque - 5500 Nm, hardness gear - 58-62 HRC.

Buying key with UKM, you should choose a device with bearings (in the construction of some gear bearings are not provided). Wrenches bearing recognized more durable.

To wrench the emphasis is not in contact with the pile during operation, its end can be cut off, leaving the factory openings. The holes we need to subsequently bolted to the gearbox telescopic focus.

Special attention is given during the operation of the gearbox. The presence of lubricant in the inner cavity care should be taken in advance. If the device is lubricated regularly and ensure that it does not overheat (to avoid overheating you need to take breaks from work), the wrench will twist without breaking a few tens of products.

skor31029 (FORUMHOUSE User):

Do not forget about lubricating the gearbox. Gears it does not break down, as it were deleted, decreasing in width and in height. Therefore, the more lubrication, the longer it runs. In the store they are dry and can be erased in a single pile.

User singer777For example, changes in the gear lubricant every 20 screwing. So draw your own conclusions. As to the lubricant, the users of our portal with practical experience of working with wrenches, recommend the use of plastic types of lubricants (SHRUS-4, etc.).

adapters

The design homemade two adapter device (adapter) is provided.

The first adapter transmits torque from the drill to the gearbox. To make it can be quite simple: the gearbox wear head (16mm, etc.), and the drill chuck to insert the appropriate bolt.

The second adapter is a well head assembly for piles having a tip at the output shaft gear square.

If you are going to use the device described, the person required to think about how to save the drill and gearbox from mechanical overload. There are two ways to solve this problem.

About the upcoming overload can be recognized by the sound of running drills. Timely off the device helps to avoid breakdowns.

Installing metal pin between the drill and the gear will not only help to avoid damage, but also save you from injury. Properly selected pin will be cut off as soon as the torque reaches a critical value.

singer777:

Morse taper is inserted into the drill Rebir company, which is connected with the next workpiece with a wire diameter of 3 mm. This wire works on the cut and serves as a protection against overload and burnout drills.

As soon as the load reaches a critical value, the gear unit with a drill must be removed from the pile. After that it is necessary to make dovinchivanie support manually.

singer777:

We twist until the bolt failure. If you then put the levers of 3 m on both sides, and to harness the four of us, then we turn the pile 1/4 turn or slightly more. Today, the bolt does not break (spare gearbox and dokruchivali hands).

Screwing the pile via the reduction gear unit (the same as in the case of screwing by hand), it is necessary to constantly monitor the level of the vertical support.

The support arm

The support arm is expedient to make the two pipes of different diameter (obtained telescopic structure with adjustable length of the lever).

To tube without bending at the point of articulation with the fastening bolt, it is possible to strengthen a small segment channel, band or bracket.

Adaptations for screwing piles, shown below, are not widely known, but they have certain advantages. And if you do it is through them that a screwed screw piles, installation costs will ultimately be lower and you will save the ruble - the other for at least important parts of the construction budget.

Installation with hydraulic drive - its reliability is somewhat higher than that of a mechanical gear.

Installing the frame - allows most accurately align the pile and reduce the complexity of the process.

Installing driven benzobura - easy to use and reliable.

What if the pile rested a snag

Installation of pile foundation is fraught with the fact that at the time of screwing the pile often rests on a rock or other object, located in the ground. And if the barrier is strong enough, it becomes a real problem. It can be solved in two ways.

If the pile does not have time to go deep, it can be unscrewed and try to remove the obstacle. Make it easy, so you can achieve a positive result is not always the case.

If the pile stops at the obstacle, but had time to delve into more than 1.5 m, it can be left in this position, then cut off the top of the horizontal level. But it is preferable in this case to unscrew and screw pile it next to (in line with the adjacent supports). This method is suitable for all piles (except those which are located on the corners of the future construction).

Corner piles must be screwed in to a sufficient depth, and their location must comply with the design layout of the foundation.

Def555:

Options: remove the stone (if the depth is small), or crushed, or pile on the side twist.
