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.

Embodiment 1

[0047] Such as Figures 1 to 2It is a fully-enclosed skin-type structure for underground waterproofing projects, including a bottom layer, a top layer, and a side layer. The bottom layer, top layer, and side layers are integrated to form a hollow structure. The bottom layer is the bottom concrete cushion layer A1 from bottom to top. , the bottom rubber asphalt waterproof coating layer A2, the bottom water-based non-curing coating layer A3, the bottom film reinforcement layer A4, the bottom concrete base layer A5; the side layer includes the side concrete base layer B5, outside the side concrete base layer B5 The side water-based non-curing coating layer B3, the side film reinforcement layer B4, and the side waterproof layer B2 are successively provided, and the side waterproof layer B2 is a rubber asphalt waterproof coating layer or a waterproof coiled material layer; the top layer includes a top concrete base layer C5, On the outside of the top concrete base layer C5, a top w...

Embodiment 2

[0055] The construction method of the fully enclosed skin formula structure of the underground waterproofing project in embodiment 1 is as follows:

[0056] Step 1, ground floor construction, which includes:

[0057] Step 1-1. After the construction of the concrete cushion of the underground project is completed, under the condition of no clear water, use mechanized spraying, and the construction is a 2mm thick rubber asphalt waterproof coating;

[0058] Step 1-2. After the construction of the rubber asphalt waterproof coating is completed (it can also be followed by simultaneous construction), use mechanized spraying to construct a 2mm thick water-based non-curing coating;

[0059] Steps 1-3, laying non-woven fabrics synchronously during the construction of water-based non-curing coatings;

[0060] Steps 1-4. After laying the non-woven fabric, directly bind the steel bars on the upper spring line, support the formwork, and carry out concrete pouring.

[0061] Step 2, side c...

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...
