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.
Moreover, cement mortar is also required during construction, which causes great pollution to the environment while increasing the cost, which is not conducive to civilized construction.

Embodiment Construction

[0039] Below in conjunction with accompanying drawing, the present invention is described in detail as follows.

[0040] figure 1 It is the front view of the concrete shaft wall module used in the present invention; figure 2 It is a top view of the concrete shaft wall module used in the present invention.

[0041] As shown in the figure, the concrete shaft wall module used in the present invention includes a left frame 12, a right frame 11 and a connecting edge 10, and the upper reference plane 1, the lower reference plane 2, the front On the datum plane 3 and the back datum plane 4, grooves 5 and convex ribs 6 are correspondingly provided respectively, an intermediate groove 8 is provided at the middle part of the upper datum plane 1 of the connecting rib 10, and a middle groove 8 is provided at the middle part of the lower datum plane 2. The middle rib 9; the middle rib 9 is connected with the left frame 12 and the right frame 11 through an arc. The space formed by the a...

Abstract

The present invention relates to a masonry construction method of the wall modules of a concrete shaft wall. The method includes eight steps: (1) the excavation of earth: according to location dimension, the excavation of earth is carried out; (2) the casting of foundation cushion concrete: according to positioning sidelines and an elevation, the foundation cushion concrete is casted; (3) the casting of foundation mat concrete; (4) the masonry of the wall modules: according to the sizes of the arranged blocks, the wall modules are piled up and the masonry matches holes, so that upper-lower and left-right tongue-and-grooves are aligned with one another; (5) the infusion of concrete: the concrete is compacted by a vibrating rod or a steel reinforcement; (6) the installation of precast lintels and cover slabs: slab joints are caulked; (7) the masonry of an inspection well; (8) the backfilling of earth: unbackfilled trenches around the wall body are backfilled at the same time. Because the present invention applies the construction method of compacting the infused mortar, the effect of compaction is ensured, thus enhancing the anti-shearing property of the wall body. Moreover, because the requirements on construction are restrict, the built wall body is firm and is not easily loosened, thus preventing the phenomenon of leakage. The present invention reduces the waterproof working procedures of the wall body, thus shortening the construction period and reducing the cost.

Description

technical field [0001] The invention relates to a building construction method, in particular to an air column construction method of a concrete well wall module with convex grooves interlocked with each other. It belongs to the technical field of construction engineering. 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...
