Concrete well wall module

Abstract

The invention relates to a concrete well wall module which comprises a left side frame, a right side frame and connecting arrises, and the upper datum plane, the lower datum plane, the front datum plane and the rear datum plane of the left side frame and the right side frame are respectively and correspondingly provided with grooves and convex arrises. The concrete well wall module is characterized in that a middle groove is arranged in the middle part of the upper datum plane of each connecting arris, and a middle convex arris is arranged in the middle part of the lower datum plane; and the middle convex arris is in arc connection with the left side frame and the right side frame. The connecting plane of the middle groove and the left side frame and the connecting plane of the middle groove and the right side frame are respectively provided with two grooves. The middle groove and the middle convex arris are arranged, so the invention enhances the shearing resistant performance. Meanwhile, because the middle convex arris is in arc connection with the left side frame and the right side frame, the effect of tamping is guaranteed. In addition, due to the adoption of a multiplex chain lock structure, the invention ensures that the wall is firmer to be not easy to loose and is less susceptible to leakage, reduces the working procedures of performing waterproof operation on the wall, shortens the labor hour and reduces cost.

Description

technical field [0001] The invention relates to a concrete well wall module, in particular to a concrete well wall module with interlocking convex grooves. It belongs to the technical field of building materials. Background technique [0002] Any building must have supporting infrastructure, such as: various inspection wells for drainage and water storage facilities, rainwater outlets, square ditches, septic tanks and small structures, etc. In the past, these infrastructures were built with brick-concrete structures. Because the city uses parallel joints, the anti-seepage effect is poor; in addition, the brick-concrete structure requires a lot of water resources, and there is mud pollution, which is very polluting; after the wall is built, It is also necessary to smear a waterproof layer on the inner and outer walls, which increases the cost and wastes time, and the work efficiency is slow. [0003] Now there are also special shaft wall modules used in on-site construction...

AI Technical Summary

Problems solved by technology

However, since the middle part is not connected to each other except for the holes where the steel bars are pierced, it is easy to cause pores or hollows during grouting and compaction, which makes the overall structure not strong enough, and also makes the waterproof and anti-leakage performance Not good, it needs to be waterproofed on the inside and outside of the wall, resulting in a longer construction period and increased costs

Moreover, the shear performance is not ideal, and it is easy to cause leakage.
