Example 1:
the waterproof protection structure of the bearing platform of the invention is explained in detail with reference to fig. 1 and 2. The waterproof protection structure includes:
the concrete cushion layer, the mortar leveling layer, the waterproof roll material layer and the fine aggregate concrete protective layer are sequentially arranged on the platform surface of the pile raft bearing platform; and the brick bed film, the mortar leveling layer, the waterproof roll material layer and the polyethylene self-adhesive plate layer are sequentially arranged on the vertical surface of the pile raft bearing platform.
The polyethylene self-adhesive plate layer is formed by splicing a plurality of polyethylene self-adhesive plates and is adhered to the waterproof roll material layer, and the bottom side edge of the polyethylene self-adhesive plate layer is poured in the fine aggregate concrete protective layer.
Specifically, the invention replaces cast-in-situ fine aggregate concrete with the polyethylene self-adhesive plate on the premise of ensuring the original function of the waterproof protective layer of the vertical surface of the bearing platform, lays the customized polyethylene self-adhesive plate along the vertical surface and the external corner of the bearing platform, pours and smashes the fine aggregate concrete on the horizontal surface outside the plane and the top surface of the bearing platform, and integrates the polyethylene self-adhesive plate and the cast-in-situ fine aggregate concrete.
Compared with the prior art, the waterproof protection layer for the vertical surface of the bearing platform has the following advantages:
firstly, the construction is convenient, and the polyethylene self-adhesive plate can be processed and paved at will according to different shapes of the side slopes of the bearing platform;
the polyethylene self-adhesive plate is small in weight, high in strength, difficult to deform and warp, moisture-proof, waterproof, fireproof and insulating;
and thirdly, materials and labor are saved, and the cost is low.
The polyethylene self-adhesive plate layer 107 is formed by cutting and laying a polyethylene self-adhesive plate with the thickness of 1000mm multiplied by 2000mm multiplied by 20 mm. That is to say, polyethylene self-adhesion board 7 is laid according to the cutting of cushion cap facade size through the polyethylene self-adhesion board of customized fixed dimension to save the engineering time, in addition, the polyethylene self-adhesion board of customized fixed dimension has also reduced the construction degree of difficulty.
The inner side of the polyethylene self-adhesive plate layer 107 is provided with a waterproof roll material layer 106, in order to obtain materials conveniently and save cost, the waterproof roll material layer 106 is a wet-laid high-polymer self-adhesive waterproof roll material layer, and the thickness of the waterproof roll material layer 106 is 1.2 mm-1.5 mm. The waterproof performance of the whole waterproof protection layer of the bearing platform is further improved by laying the waterproof roll material layer 106.
In order to ensure the laying smoothness and the waterproof effect of the waterproof roll material layer 106 and the polyethylene self-adhesive plate layer, the mortar leveling layer 105 is arranged on the inner side of the waterproof roll material layer 106, and the thickness of the mortar leveling layer 105 is 20 mm.
Certainly, a foundation pit soil body is arranged below the pile cap, in order to ensure the stress stability of the bottom of the pile cap and prevent silt, water and the like from impacting a bottom plate of the pile cap, a concrete cushion layer 102 is arranged between the waterproof protective layer of the bottom plate of the pile cap and the soil body, and the thickness of the concrete cushion layer 102 is 100 mm.
In order to ensure the structural stability and excellent waterproof effect of the waterproof protective layer of the whole bearing platform facade, the places except the bearing platform facade, such as the bearing platform bottom surface and the bearing platform top surface, are the C20 concrete protective layer, and the polyethylene self-adhesive plate layer 107 and the adjacent C20 concrete protective layer form an integrated structure. That is to say, the polyethylene self-adhesive plate layer 107 at the vertical face part of the bearing platform and the C20 concrete protective layer of the non-bearing platform vertical face area together form a complete waterproof protection system at the vertical face part of the bearing platform.
With reference to fig. 1, this embodiment further provides a method for constructing a waterproof protective layer on a vertical surface of a platform, including the following steps:
step S1 measuring the size of the vertical surface of the platform: in order to ensure that the polyethylene self-adhesive plate with fixed size can be well adhered to the vertical surface of the bearing platform for laying, the size of the vertical surface of each bearing platform needs to be measured.
Step S2, processing and paving the waterproof protective layer at the vertical surface of the bearing platform: and processing the polyethylene self-adhesive plate with fixed size according to the measured data, and paving the processed polyethylene self-adhesive plate on the vertical surface of the bearing platform to be used as a waterproof protective layer at the side slope of the bearing platform.
Step S3 casting and tamping the waterproof protective layer on the plane part: after the polyethylene self-adhesive plates of all bearing platform vertical surfaces are paved, 50-thick C20 fine-stone concrete protective layers are poured on the bottom surfaces of the bearing platforms and the external corners of the bearing platforms, the polyethylene self-adhesive plate layers 107 and the cast-in-place C20 fine-stone concrete are integrated, the paved polyethylene self-adhesive plates are further fixed, and therefore the integral waterproof effect of the whole bearing platform vertical surface waterproof protective layer is guaranteed.
In summary, according to the waterproof protection layer for the vertical face of the pile cap, the concrete cushion layer, the mortar leveling layer, the waterproof roll material layer and the polyethylene self-adhesive plate layer are sequentially paved on the vertical face and the plane part of the pile cap, so that the problems that the waterproof protection layer for the vertical face part of the pile cap is difficult to construct, the construction quality is difficult to guarantee and the construction cost is high are solved. In addition, the fine aggregate concrete protective layer is poured in the areas such as the bottom surface of the bearing platform, the top surface of the bearing platform and the like outside the vertical surface of the bearing platform to serve as a waterproof protective layer, and the polyethylene self-adhesive plate layer and the fine aggregate concrete protective layer form an integrated structure, so that the whole pile-bearing platform is guaranteed to form a complete waterproof system.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
