A construction device for pile foundation engineering

Abstract

Disclosed is a construction device for a pile foundation project. The construction device comprises one or more groups of annular rotary plate assemblies and motor and driving assemblies, and a rigid structure support, wherein the annular rotary plate assemblies comprise annular rotary plates and multiple rotary wings which are disposed at the front ends of the annular rotary plates; the annular rotary plates are driven to operate by the one or more groups of motor and driving assemblies; the motor and driving assemblies comprise motors, driving shafts and driving gear sets; the annular rotary plate assemblies and the motor and driving assemblies are fixed to the rigid structure support. By means of the construction device, the construction performed on the outer side of a rigid pile is avoided; therefore, pile sinking of the rigid pile can be performed under the low stress application of an aboveground pile frame, and modified soil containing cemented soil or replacement soil containing using concrete or mortar can be formed around the rigid pile; the construction efficiency and the construction quality are improved; cost is reduced.

Description

technical field [0001] The invention relates to a construction device for foundation engineering. Background technique [0002] The existing rigid-flexible composite pile construction method generally adopts first to complete the construction of the flexible pile (such as cement-soil mixing pile), and then complete the construction of the rigid pile within a few hours after the construction of the flexible pile is completed. The main shortcomings of this construction method: 1. Because the flexible pile and the rigid pile are constructed twice, this construction method cannot fully guarantee the same core of the flexible pile and the rigid pile; 2. The power of the existing flexible pile construction equipment is generally set at On the frame, the power is transmitted to the sprinkler head or the stirring shaft through the tens of meters long axis that frictionally rotates in the soil, not only the loss of kinetic energy is large, but also the power configuration of the equi...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a construction device suitable for pile foundation engineering. The construction device for pile foundation engineering solves the construction problem on the outside of the rigid pile, thereby realizing the construction of the pile frame on the ground under lower force. The pile sinking of rigid piles can realize the formation of modified soil including cement soil or replacement soil including concrete or mortar around the rigid piles. The construction device improves construction efficiency and construction quality, and saves costs
