Problems solved by technology

At the same time, static pressure piles often encounter a layer of silt layer in the ground during construction, so that the static pressure piles cannot pass through and affect the bearing capacity of the piles. For this situation, the pile pressure of the pile driver can only be increased at present, but static pressure piles cannot pass through. The self-strength of the pressure pile limits the further enhancement of the pressure pile force, so that the bearing capacity of the static pressure pile cannot be fully exerted

Abstract

A construction machine for constructing the composite pile features that a static pile driving mechanism and a stirred pile constructing mechanism or high-pressure chemical churning pile constructing mechanism are installed on a single hydraulic walking carrier. After the stirred pile or chemical churning pile is constructed, the carrier moves by a predefined distance and the static pile driving mechanism is used.

Description

technical field [0001] The invention relates to a geotechnical engineering construction machine, in particular to a cement-soil core-inserted composite pile construction machine. Background technique [0002] The cement-soil cored pile is to inject cement slurry and other materials into the foundation through deep mixing or high-pressure rotary spraying and fully mix with the foundation soil to form a continuous cement-soil pile. A prefabricated pile is inserted to form a composite pile. The bearing capacity and various performances of this pile are significantly improved compared with a single pile. The current method of constructing this kind of pile is usually to use two pile machines, first use the stirring pile machine to carry out the construction of the stirring pile or use the high-pressure rotary spraying pile machine to carry out the construction of the high-pressure rotary spraying pile, and remove the stirring pile machine or the high-pressure pile machine after ...
