Rapid Piling Construction Machinery for Soft Soil Highway Base

Abstract

The invention discloses a fast piling construction machine for soft soil road base, which comprises double-bar handles, a main body and a drill head, wherein the main body is in a cylinder structure;the drill head is arranged at the bottom of the main body; two symmetrical double-bar handles are arranged at the top end of the main body opposite to the drill head; the double-bar handles is horizontally welded with the main body, wherein the main body is mainly composed of a drainage structure, a soil cavity and a shell; the shell and the double-bar handles are horizontally fixed; the inner space of the shell is a soil cavity; the shell is provided with an internal and an external layer and internally provided with a drainage structure; through the matching between the drill head and the drainage structure, the frozen soil of the soft soil road base is taken out by a screw pressing downwards. This piling mode is safer and more labor-saving, and the ice water melted by friction in the process is discharged through the drainage structure, so that the secondary freezing is avoided in the soil cavity.

Description

technical field [0001] The invention relates to the field of soft soil road bases, in particular to a rapid piling construction machine for soft soil road bases. Background technique [0002] The soft soil foundation is mainly composed of organic soil, peat with large pores, soft and loose sandy soil, etc. In these soil layer structures, it mainly contains fine particles such as clay and silt, so the soft soil foundation is consolidated. Slow, large deformation, low strength, and contains a large amount of water. The soft soil foundation in Gaozang area will freeze at low temperature and form frozen soil. Vehicles can be driven in severe winter. Once summer arrives, the temperature When the permafrost dissolves, subsidence will occur. When the permafrost in the high-zang area has not yet dissolved, pilings need to be installed to install cooling structures to ensure that the road is cooled when the temperature rises to avoid subsidence. At present, the following problems hav...

AI Technical Summary

Problems solved by technology

[0003] 1. Although the hardness of permafrost in soft soil foundation is not as good as that of concrete, it is also higher than ordinary ones. When excavators and other construction machinery are used to shovel soil, the tip of the bucket is generally a triangular plate, which is easy to break and the damaged area is relatively large;

[0004] 2. After the piling is completed, the frozen soil cannot be completely removed, and secondary freezing will occur on the construction machinery
