a gas explosion device

Abstract

A gas explosion device, comprising a cylinder, the cylinder includes a cylinder, a piston, a piston rod, the upper end of the cylinder is provided with a cylinder front cover, the lower end is provided with a cylinder rear cover, and the inner ring of the cylinder is respectively fixed with the cylinder; the middle ring of the cylinder is connected with the front of the cylinder The cavity between the covers constitutes the gas explosion chamber, and the cavity between the cylinder back cover constitutes the energy storage chamber; the gas explosion hole is set on the lower cylinder wall in the gas explosion chamber; the pilot piston moves in the gas explosion chamber; the energy storage piston moves in the gas explosion chamber. The piston rod moves through the front cover of the cylinder, the pilot piston, the middle ring of the cylinder from top to bottom, and the bottom end of the energy storage piston is fixed with the energy storage piston; the piston rod slides with the pilot piston and the middle ring of the cylinder, and the energy storage piston It is closely matched with the piston rod; air holes are set on the front cover of the cylinder, the pilot piston, and the middle ring of the cylinder; the air pressure cover on the top of the piston rod and the upper end of the air inlet hole of the front cover can be airtightly matched; Provide horizontal channels; cooperate with tamping vibration waves to speed up soil drainage and consolidation speed, treatment depth, and reduce post-construction creep.

Description

technical field [0001] The invention relates to the technical field of treating saturated soft soil foundations by a dynamic compaction method, in particular to an air explosion device, which quickly generates drainage channels through air explosions to deal with the problem of difficult drainage caused by silting of saturated soft soil foundations. Background technique [0002] Soft soil is mostly distributed in the southeast coast of our country. With the production development of human society and the continuous increase of population density, more and more soft soil will be used as the foundation of buildings. Soft soil has high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, various The physical and mechanical properties of different layers are quite different. Thes...
