Full surrounding skin-type structure of underground waterproof engineering and construction method

Abstract

The invention relates to the technical field of waterproof construction, in particular to waterproof technologies of underground engineering such as subways, underground pipelines, tunnels, underground pipe corridors, underground garages and underground air defense facilities, and discloses a full surrounding skin-type structure of underground waterproof engineering and a construction method. The full surrounding skin-type structure of the underground waterproof engineering comprises a bottom layer, a top layer and a side face layer; the bottom layer, the top layer and the side face layer are surrounded to be whole and form a hollow structure; water-soluble non-curing coating layers and thin film reinforcing layers are arranged on the bottom layer, the top layer and the side face layer correspondingly; and the bottom water-soluble non-curing coating layer, the side face water-soluble non-curing coating layer and the top water-soluble non-curing coating layer form the integrated seamless connection full surrounding structure. According to the full surrounding skin-type structure of the underground waterproof engineering and the construction method, the defects that in the prior art, as for the underground waterproof engineering, whole failure or leakage in local joints are easy to occur are overcome.

Description

technical field [0001] The invention relates to the technical field of waterproof construction, in particular to waterproof technologies for underground projects such as subways, underground pipelines, tunnels, underground pipe galleries, underground garages, and underground air defense facilities. Background technique [0002] Various waterproof structures and construction techniques can be used in underground waterproofing projects, and there are many waterproof materials available, such as rigid waterproofing, flexible waterproofing, rigid and flexible combined waterproofing. Among them, flexible waterproofing (waterproofing in the general sense of the waterproofing industry) is roughly divided into coating film waterproofing, coiled material waterproofing, and coating film and coiled material composite waterproofing. Its waterproof mechanism is to cover one layer, multi-layer or multi-layer composite waterproof layer on the outside of the concrete structure, so as to blo...

AI Technical Summary

Problems solved by technology

Even with a better combination of pre-paved anti-adhesive technology, the construction is more difficult. When the protective layer is directly tied to the waterproof layer, it is easy to damage the waterproof layer, and the protective layer reduces the integration of the waterproof layer and the main structure. sex

[0004] Therefore, the traditional underground waterproof technology has shortcomings in the bottom part

Especially from the perspective of the overall waterproof structure, because the waterproof material finally becomes a solidified rigid structural material after construction, if the waterproof layer and the structural plate follow the subsidence and cracking of the cushion layer due to changes in the earth’s crust, settlement, and collapse. The concrete structural slab is detached, forming a water channeling layer, which leads to the overall failure of the waterproof structure; in addition, due to the seams at the overlapping joints of the waterproof membrane during construction, it becomes a weak link in its waterproofing

Therefore, the underground waterproofing works using the above-mentioned prior art have the disadvantages of easy overall failure or easy leakage at local joints.
