Description

Technical Field

[0001] The present application belongs to the technical field of underground building construction, and specifically relates to a basement pile-wall integrated construction structure and a construction method. Background Art

[0002] With the development of modern cities, the development and utilization of urban underground space has become a global development trend and an important indicator of urban modernization. Foundation pit support is an important engineering content in the development of underground space. In foundation pit projects with retaining structures, it also involves the joint action of soil, support structure and underground structure.

[0003] However, at present, the support piles are generally only used as temporary support structures. After the foundation pit project is completed, their role is completely ignored and they are abandoned underground. A certain distance is left between the conventional support piles and the basement outer wall to facilitate the formwork and steel bar binding, waterproofing and insulation construction of the basement outer wall. The basement outer wall and support piles are calculated according to different working conditions in the permanent stage and temporary foundation pit excavation stage, respectively, without considering their joint effect. Summary of the invention

[0004] The purpose of this application is to provide a basement pile-wall integrated construction structure and construction method, which solves the problem of abandoned temporary support piles.

[0005] The purpose of this application is achieved through the following technical solutions:

[0006] A basement pile-wall integrated construction structure includes supporting piles, a basement floor and a basement floor. The pile ends of the basement floor and the basement floor are both in contact with the supporting piles. The pile ends of the basement floor are provided with structural side beams located below. The pile ends of the basement floor and the basement floor are provided with water-stopping ridges located above. Drainage ditches are formed between the supporting piles and the water-stopping ridges on the basement floor and the basement floor. The drainage ditches on the upper and lower layers are connected by drainage pipes. The drainage ditch on the basement floor is connected to the intercepting ditch on the basement floor through a water guide pipe. A lining wall masonry structure is provided on the water-stopping ridge.

[0007] Furthermore, the base surface of the supporting pile is provided with a first waterproof coating layer.

[0008] Furthermore, the lining wall masonry structure is provided with decorative aluminum plates and / or maintenance shutters.

[0009] Furthermore, a second waterproof coating layer is provided at the bottom of the drainage ditch.

[0010] Furthermore, the drainage ditch and / or intercepting ditch is a prefabricated component or a masonry structure.

[0011] A basement pile-wall integrated construction method comprises the following steps:

[0012] The first step is support optimization, which is to optimize the design of the support structure as a permanent structure;

[0013] The second step is support construction. According to the measurement results, the support piles are constructed;

[0014] The third step is the construction of the main structure of the basement, including the construction of the basement floor and the basement floor. The pile ends of the basement floor and the basement floor are both abutted against the supporting piles, and the pile ends of the basement floor are constructed with structural side beams located below;

[0015] The fourth step is to chisel out the waist beam, and gradually chisel out the supporting waist beam of the supporting piles according to the third step, and repair the base surface of the supporting piles;

[0016] The fifth step is to construct the water-stopping ridge. A water-stopping ridge is constructed at the upper end of the piles of the basement floor and the basement floor for the second time, or the fifth step is constructed simultaneously with the third step. Drainage ditches are formed between the supporting piles and the water-stopping ridge on both the basement floor and the basement floor.

[0017] The sixth step is ditch construction, which involves waterproofing the inside of the drainage ditch and fixing the main body of the drainage ditch, and fixing the intercepting ditch on the basement floor;

[0018] Step 7: Install water pipes, connect the drainage pipes between the drainage ditches on the upper and lower floors, and connect the water pipes between the drainage ditches on the basement floor and the intercepting ditches on the basement floor;

[0019] The eighth step is lining wall construction, which involves constructing the lining wall masonry structure on the water stop ridge.

[0020] Furthermore, the fourth step of repairing the base surface of the supporting piles includes: repairing the damage on the base surface of the supporting piles caused by chiseling out the supporting waist beam; cleaning and repairing the base surface of the supporting piles with cement mortar to perform surface trimming and leveling; sealing local leaks and anchor holes with waterproof materials; and applying waterproof coating on the base surface of the supporting piles by spraying and / or manual brushing.

[0021] Furthermore, in the sixth step, the drainage ditch body and / or intercepting ditch are prefabricated parts or masonry structures.

[0022] Furthermore, in the eighth step, decorative aluminum plates are installed on the lining wall masonry structure to decorate and beautify the lining wall.

[0023] Furthermore, in the eighth step, maintenance shutters are installed on the lining wall masonry structure to serve as later maintenance openings.

[0024] Beneficial effects of this application:
