Pile planting construction method for steel sheet piles

Abstract

The invention discloses a pile planting construction method for steel sheet piles. The pile planting construction method comprises the following steps: S1, guiding holes at positions, which are corresponding to lock catches of each of the steel sheet piles, on a soil body; S2, enabling a water jet cutter to penetrate through groove bodies of the steel sheet piles, wherein a jet nozzle of the water jet cutter faces the soil body, and is used for jetting high-pressure water; S3, aligning the lock catches of the steel sheet piles with the guided holes, and continuously pressing the steel sheet piles into the soil body in a static pressure manner; meanwhile, monitoring the verticality of each steel sheet pile by adopting an infrared centring device. The pile planting construction method disclosed by the invention has the advantages that friction can be reduced, so that the steel sheet piles can be pressed into the hard soil body more easily; the vibration is small, and the noise is small.

Description

technical field [0001] The invention relates to a construction method for planting steel sheet piles. Background technique [0002] At present, the pile construction methods of ultra-long steel sheet piles mainly include vibration method and static pressure method. The vibration method is to use a crane to lift a vibrating hammer, and use the hammering force generated by the vibration to drive the steel sheet pile into the soil. The static pressure method uses a static load to press the steel sheet pile into the ground to a specified depth. For ultra-long steel sheet piles in hard ground, there are currently auger drilled holes in advance, and then static pressure is used to press the steel sheet piles into the soil layer. [0003] Yet above-mentioned construction method has following defective: [0004] (1) The traditional vibration method is not enough to control the verticality. If the front pile is not vertical, the rear pile will be difficult to drive in. At the same...

AI Technical Summary

Problems solved by technology

[0004] (1) The traditional vibration method is not enough to control the verticality. If the front pile is not vertical, the rear pile will be difficult to drive in. At the same time, the vibration method will cause large vibration and noise during construction, which will have a great impact on the surrounding environment

[0005] (2) Although there is no vibration and zero noise during the construction of the traditional static pressure method, when the pressing is carried out, the locking position of the steel sheet pile and the groove body of the steel sheet pile are subjected to a large friction force, and due to insufficient static pressure, the pressure of the pressing pile Both diameter and press-in depth are limited

Especially for hard ground construction, it will be difficult to press in, and it is difficult to guarantee the control of verticality

[0006] ⑶Using spiral pre-drilling, and then constructing steel sheet pile static pressure pressing technology, the soil layer will be greatly disturbed, the strength of the foundation will be affected, and the stability of the supporting structure will be greatly reduced
