Problems solved by technology
When inserting and pulling out the traditional Larsen steel sheet pile, due to the existence of the interlocking structure at both ends, the resistance of the interlocking structure and the steel plate part is different, which can easily cause the pile body to tilt, which will adversely affect the construction and engineering safety.

Abstract
The invention discloses a guide component for improving the construction performance of a Larsen steel sheet pile. The Larsen steel sheet pile comprises wing plates, ribbed plates, and interlocking structures located on the outer sides of the wing plates on the two sides, the guide component comprises a corner resistance increasing device and a stiffening rib, the corner resistance increasing device is inserted in the bottom corner of the wing plate and the ribbed plate of the Larsen steel sheet pile, the stiffening rib is detachably inserted on the ribbed plate and used for reinforcing the rigidity of the Larsen steel sheet pile, the corner resistance increasing device comprises a guide end and a fixing end, the guide end and the interlocking structure of the Larsen steel sheet pile are the same, the fixing end is formed in a way that one side plate of the guide end extends inwards by 90 degrees, wedge shaped openings are formed at the upper part and the lower part of the fixing end,the size of the wedge shaped opening is equal to the thickness of the Larsen steel sheet pile, the turning angle of the Larsen steel sheet pile is inserted into the wedge shaped opening; the detachable stiffening rib is a right triangle. The guide component is simple and practical, runs conveniently, greatly reduces the construction cost, and effectively solves the problems that a body of the traditional Larsen steel sheet pile inclines easily and the steel sheet pile needs to be supported internally and pulled externally when used for supporting.
Description
technical field [0001] The invention relates to the construction field of Larsen steel sheet piles, in particular to a guide assembly for improving the construction performance of Larsen steel sheet piles. Background technique [0002] In the construction of water conservancy projects, dry land construction is a necessary condition. Due to the limitations of the construction site and environmental protection, the Larsen steel sheet pile cofferdam is the preferred solution. Larsen steel sheet pile is a kind of steel structure with linkages on the edge, and the linkages can be freely combined to form a continuous and compact retaining wall or water retaining wall. When inserting and pulling out the traditional Larsen steel sheet pile, due to the existence of the interlocking structure at both ends, the interlocking structure and the steel plate part suffer from different resistances, which can easily cause the pile body to tilt, which will adversely affect the construction and...
