Splicing type snowflake steel plate pile capable of monitoring self deformation and construction method thereof

Abstract

The invention discloses a splicing type snowflake steel plate pile capable of monitoring self deformation and a construction method thereof. A steel plate pile body section is in a snowflake shape formed by three Y shapes with included angles of 120 degrees; optical fibers for monitoring the self deformation are distributed on the steel plate pile body, and the optical fibers are connected with adata receiver; the splicing type snowflake steel plate pile comprises a bottom end splicing pile, a middle segment splicing pile and a top end splicing pile; and the splicing piles are spliced and reinforced through a mode of inserting an inverted T shape into a U shape. According to the splicing type snowflake steel plate pile capable of monitoring the self deformation and the construction methodthereof, real-time monitoring is carried out on the self pile body through the optical fibers, the punching depth is controlled in real time through a scaleplate, and the self features are known through a two-dimensional code, so that the design of the steel plate pile is more scientific and more modernized. The required pile body length can be spliced, and the problems of difficult overlong steel plate pile transportation, prone blocked and inclined piling and difficult piling of underground low space are solved; the snowflake section has larger bearing capacity, can be used for engineeringof higher requirements of differential settlement, and the problems of bump at bridge-head and soft foundation reinforcing are solved.

Description

technical field [0001] The invention relates to steel sheet piles in geotechnical and foundation engineering, in particular to a spliced ​​snowflake-shaped steel sheet pile capable of monitoring its own deformation and a construction method thereof. Background technique [0002] With the development of the times, the development of underground space is increasing, and pile driving is required for foundation treatment in some underground space environments such as tunnels. As time goes by, there are a series of problems that some buildings need to be heightened, or the foundation of the building needs to be strengthened, and the building needs to be corrected due to its inclination. However, in the process of carrying out the above-mentioned several works, it is difficult to drive piles during foundation treatment. Its reason is that the processing of some pile foundations needs to be finished inside the tunnel and the original building, and the height of the tunnel interior...
