Abstract
Description
technical field
[0001] The invention relates to the field of road protection construction, in particular to a semi-automatic road construction device for quickly implementing equipment-based construction operations on expansive soil, in particular to a rapid drilling and piling equipment for road protection construction on expansive soil sections. Background technique
[0002] Expansive soil is a kind of highly plastic clay with high bearing capacity in general. It has the characteristics of water absorption expansion, water loss shrinkage and repeated expansion and contraction deformation, water immersion bearing capacity attenuation, drying shrinkage crack development, etc., and its properties are extremely unstable.
[0003] In the design of road engineering, the physical and mechanical properties of expansive soil need to be based on the detailed report of geological survey and the experience of dealing with expansive soil. The design adopts the idea of comprehensive tr...
