Description
Technical field
The utility model belongs to technical field of buildings, and specially a kind of outer wall of underground structure connects raft position water proof structure.
Background technique
With the development of underground waterproof technology, waterproof material is continued to bring out, and meets raft portion to building outer wall of underground structure
The water-proofing treatment of position directly influences the performance of underground structure.Outer wall of underground structure connects raft position water proof structure and to constantly bring forth new ideas,
Practical problem can be improved in the case where technical feasibility, process, guarantee quality.
Utility model content
The utility model aim is to provide a kind of outer wall of underground structure with deficiency aiming at the problems existing in the prior art
Connect raft position water proof structure.
To reach above-mentioned purpose, technical solution used by the utility model is as follows:
A kind of outer wall of underground structure connects raft position water proof structure, including concrete cushion, MBP coil waterproof layer, concrete
Layer, steel plate for sealing water and metal nail, the concrete cushion pour on the ground, and the concrete cushion building includes ground exterior wall
Wall and concrete layer wall, the concrete layer wall are located at ground outer wall body towards indoor side, the ground exterior wall
Wall and concrete layer wall have one section of vertical splicing seams, the concrete layer wall and concrete cushion and concrete layer
Be equipped with one layer of MBP coil waterproof layer between wall and ground outer wall body, and MBP coil waterproof layer from concrete layer wall with
It extends out in gap between ground outer wall body, bends and fit to ground outer wall body upper surface, and solid with metal nail
It is fixed.
Further, the concrete cushion using C15 concreting and pours with a thickness of 100mm.
Further, MBP coiled material long edge position uses the overlapping mode on self-adhesion side, and short side uses the overlap joint of cementation zone
Mode；The long side lap width is not less than 80mm, and short side lap width is not less than 50mm.
Further, the concrete is poured using self-waterproof concrete.
Further, the steel plate for sealing water it is wide not less than 300mm, it is thick not less than 3mm, it is long depending on exterior wall length and
The steel plate for sealing water uses Q235 steel.
Further, the metal nail is arranged along exterior wall length direction, and setting spacing is 500mm.
By above the technical solution of the utility model it is found that the utility model has the beneficial effects that:
A kind of outer wall of underground structure of the utility model connects raft position water proof structure, connects raft position with traditional outer wall of underground structure
Water proof structure is compared, and this method constructing operation is simple and direct, and progress is fast, and meets Cha Chu using MBP coiled material new waterproof material in exterior wall
Steel plate for sealing water is arranged in material, and dual water proof anti-seepage, impermeability is strong, tensile strength is high, guarantees that outer wall of underground structure is impermeable, and
Convenient and quick construction, waterproof quality are easy to get guarantee.
Detailed description of the invention
Fig. 1 is that a kind of outer wall of underground structure of the utility model connects raft position water proof structure schematic diagram.
In figure: 1, concrete cushion；2, MBP coil waterproof layer；3, concrete layer；4, steel plate for sealing water；5, metal nail.
Specific embodiment
In order to make related personnel know more about the technology contents of the utility model, now by specific embodiment and institute's accompanying drawings knot
It closes, is described as follows.
A kind of outer wall of underground structure of the utility model connects raft position water proof structure figure as shown in Figure 1, its construction method, including
Following steps:
Step 1: being laid with concrete cushion；Bed course is poured using C15 concrete, pour bed course with a thickness of 100,
Ensure the smooth of mat surface, facilitates the laying of MBP coiled material；
Step 2: being laid with MBP coil waterproof layer；The laying after external wall structure base to waterproof roll progress large area is cleared up,
Coiled material is laid with using single layer, when moisture substrate is laid with, basal plane answer it is smooth it is firm, without bright water and must be completely viscous, MBP coiled material long side
Lap width is not less than 80mm, and short side lap width is not less than 50mm；When elevation construction, in self-adhesion side positional distance coil edge
In 10mm~20mm, metal nail is placed every 400mm~600mm, coiled material is mechanically fixed, and should ensure that fixed position quilt
Coiled material is completely covered；Coiled material long side should use self-adhesion edge lap, and short side should be overlapped using cementation zone, and roll end overlap answers phase
It is mutually staggered, it is noted that waterproof layer must not be damaged when pouring structure concrete.
Step 3: concreting；External Wall carries out pouring for concrete, and the concrete poured is water-proof concrete and resists
Compressive Strength is not less than C30, and anti-permeability strength is not less than P6.
Step 4: steel plate for sealing water is placed；Width 300mm, the steel plate of thick 3mm are placed in concrete layer, selection material is Q235
Steel, the placement of steel plate for sealing water, which should meet water, to be faced outwardly, and first pours part and each half in rear part.
Although the utility model has been disclosed with preferred embodiment as above, so it is not intended to limit the utility model.This reality
It is without departing from the spirit and scope of the utility model, each when that can make with novel those of ordinary skill in the art
Kind changes and retouches.Therefore, the protection scope of the utility model is subject to view those as defined in claim.
