As withstand protective layer by pouring concrete foundation in the ground

Hello.

I think many people know that the valve stack is close to the outer surface of the w / b construction impossible. The outer layer provides a concrete joint work of all elements of the product and protects the metal from rusting and collapse during a fire.

The thickness of the protective layer for various structures shown in the SP 63.13330.2012 and the SNIP 2.03.01-84 *, but now is not about that.

When it comes to pouring into the mold, the issues do not arise. We put the plastic retaining clips and forgotten. But when pouring into the ground this way of working is not always.

To install at the bottom of excavation needed latches rack-poppet (preferably solid) with a base. And if the filling is no concrete preparation, their height should be 70 mm (see. P. 5.5 SNIP 2.03.01-84 *). Find these clips is not always possible. Yes, and the price for them in the regions often "bite".

As for side fixing, use the standard "star" receives only melkozaglublennyh foundations. They balk at the bottom formwork board and that was enough. If more than one meter burial until uvyazhesh all fittings, "star gnaw" currently in the ground grooves. The protective layer decreases.

On one of the objects of the customer in advance bought locks-chairs. The soil they leave the children to school. On the site there were many old brick and we are fit to enclose it under the "chairs". Hemorrhoids are one else. More in such adventures do not get involved.

When not exerted in the presence of relevant clamps used conventional pipes. From the "weave" rings cut the required length and underlay for reinforcement. Attempts to save and put the tube F50 failed. They are unstable. Annoying to correct.

Such pads do not only below but also sideways in places of installation of "short stacks". We called shorty cross bars, which put to longitudinal reinforcement less playing space. First, on both sides of the pipe underlay segments, then inserted shorty, pressed longitudinal reinforcement to clamp and fasten it.

On this I have everything. Thank you for reading! If the article was helpful subscribe to the channel. Best thanks to me - your Like and repost.
