Combined steel plate pile construction guide frame and construction method of combined steel plate pile

Abstract

The invention discloses a combined steel plate construction guide frame and a construction method of a combined steel plate pile. The construction guide frame comprises a guide frame main body frame structure, a positioning fine tuning system and an anchor pile, wherein the anchor pile is connected with the guide frame main body frame structure, the positioning fine tuning system is in a bi-layer structure, and the bi-layer structure is respectively arranged at the upper portion and the lower portion of the guide frame main body frame structure. The construction guide frame has functions of self stable, bi-layer of upper and lower and bi-direction of guiding and positioning, and secondary positioning, namely, after the construction guide frame positions one time and the steel pipe piles are inserted, the opposite position of each steel pipe pile can not be guaranteed, thus by means of secondary positioning and fine tuning, accurate positioning is guaranteed. Due to the adoption of a frame structure, the construction guide frame has the advantages of being enough in rigidness and intensity, capable of being hoisted integrally, fast, convenient, simple in positioning and operation, relatively convenient when people constructs, and capable of reducing intermediate links.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to a combined steel sheet pile construction guide frame and a combined steel sheet pile construction method. Background technique [0002] The shipping basin of the port includes water track and land track. Among them, in order to prevent water seepage and soil leakage, the water track foundation harbor pool wall adopts a combined steel sheet pile structure. [0003] Most of the existing combined steel sheet pile structures are steel pipe piles with locks welded on them, and the steel pipe piles and steel sheet piles are connected through the lock buckles on the steel pipe piles to form a combined steel sheet pile structure. The construction of the combined steel sheet pile of this structure is difficult: 1. The steel sheet pile and the steel sheet pile are tens of meters long, and the pile is very long, so the construction is difficult; 2. The pile position an...

AI Technical Summary

Problems solved by technology

The construction of the combined steel sheet pile of this structure is difficult: 1. The steel sheet pile and the steel sheet pile are tens of meters long, and the pile is very long, so the construction is difficult; 2. The pile position and verticality require high precision, and the connection between the steel sheet pile and the steel pipe pile Large lock friction resistance

The overall construction speed of steel pipe piles and steel plates is slow, which affects the overall construction progress
