Temporary blocking structure for clearances of support piles and construction method of temporary blocking structure

Abstract

The invention provides a temporary blocking structure for clearances of support piles and a construction method of the temporary blocking structure. The temporary blocking structure comprises first reinforcing bars, second reinforcing bars and templates, wherein the first reinforcing bars are vertically planted on the sides, back to a soil body, of the support piles at intervals along the support piles; the first reinforcing bars have exposed end parts formed on the surfaces of the support piles; the second reinforcing bars are horizontally fixedly connected with the exposed end parts, in positions with the same or similar heights on the support piles, of the first reinforcing bars; one template is arranged in the position, on the inner sides, facing the soil body, of the second reinforcing bars, between the two arbitrary adjacent support piles; and a clearance between the two arbitrary adjacent support piles is blocked by the template. According to the temporary blocking structure, through the technical scheme, the technical problems that conventionally, the clearances of the support piles on one side of a firstly constructed foundation pit are liable to cause water and soil loss due to rain, and a soil body outside the pit collapses are solved, and the purpose that silt of the clearances of the support piles does not leak to the inner side of the foundation pit during the earth excavation period is achieved, so that the project operation efficiency is improved, and beneficial technical effects such as stability of the foundation pit are maintained.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a construction technology for temporarily sealing gaps between foundation pit support and protection piles. Background technique [0002] Supporting piles are generally used for foundation pit support, side slope support and landslide control, and are used to bear horizontal earth pressure or landslide thrust. Among them, the foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. [0003] It is worth noting that the foundation pit area is large, and support piles or temporary connecting walls are mostly used for separation construction. The two separated foundation pits are usually not constructed at the same time but successively. However, the...

Problems solved by technology

[0004] In view of the above situation, the present invention provides a temporary plugging structure and construction method for the gap between the supporting piles. By setting temporary plugging between the gaps between the supporting piles, it solves the problem that the gap between the supporting piles on the side of the foundation pit was first constructed in the past. Water and soil loss due to rain, causing technical problems of soil collapse outside the pit, to ensure that the silt in the gap between the supporting piles does not leak to the inside of the foundation pit during the earthwork excavation, thereby improving the efficiency of engineering construction and maintaining the stability of the foundation pit Sexual and other beneficial technical effects
