Abstract

The invention relates to the technical field of steel sheet pile construction, and discloses a construction method for introducing holes into steel sheet piles in soft rock formations, including a plurality of steel sheet piles with locks and locks at both ends, and adjacent steel sheet piles pass through the locks and locks. The buckles are locked sequentially, and the steps are as follows: (1), the site is leveled, and the position of the lead hole pile and the axis are measured and positioned; (2), multiple times of drilling, forming multiple arranged lead holes; (3), the steel plate Pile sinking construction; (4), lifting the steel sheet pile, so that the steel sheet pile is vertically in place; the lock of the steel sheet pile is inserted into the lock of the adjacent steel sheet pile, and the hydraulic vibration pile driver sinks the steel sheet pile; (5), multiple Steel sheet piles are sunk one by one along the arrangement direction of multiple lead holes. In this way, the amount of soil taken is greatly reduced, and the construction efficiency is improved. It is suitable for the steel sheet pile support construction under the geological conditions of soft rock formations; Under the geological conditions of soft rock formations, the steel sheet piles sink into the soil smoothly.

Description

technical field [0001] The patent of the present invention relates to the technical field of steel sheet pile construction, and specifically relates to a construction method for leading holes driven by steel sheet piles in soft rock formations. Background technique [0002] Steel sheet pile construction refers to the construction process in which steel sheet piles are inserted into the ground to support the foundation pit. [0003] The steel sheet pile is a type of steel with a linkage lock device on the edge. This lock can be fastened to form a continuous and compact steel structure for retaining soil or water. It is suitable for various buildings (structures) and municipal, Water conservancy, highway, underground rail transit and other foundation pit support projects have the advantages of convenient construction, plug and play, high reuse rate, environmental protection and pollution-free, etc., which meet the requirements of green construction and are widely used.
