Slurry stirring equipment for geotechnical engineering

Abstract

The invention provides a slurry stirring equipment for geotechnical engineering. A stirring shaft of the slurry stirring equipment for the geotechnical engineering comprises a first cavity, a first channel, a first air bag and an air bag reciprocating compression mechanism, wherein the first cavity is formed inside the upper end of the stirring shaft, the first channel is formed inside the stirring shaft in the longitudinal direction of the stirring shaft, the first air bag is arranged in the cavity and connected to an inflation pump through an inflation pipe, the air bag reciprocating compression mechanism makes contact with the inflated first air bag, each stirring blade comprises a fixed blade body and a movable blade body, grooves are formed in the upper surfaces of the fixed blade bodies, the movable blade bodies are slidably connected into the grooves in the depth direction of the grooves, a second air bag is further arranged below the movable blade body and communicates with an air inlet and outlet main pipe through an air inlet and outlet branch pipe, the air inlet and outlet main pipe is arranged in the first channel, and communicates with the first air bag. According to the slurry stirring equipment, in the process that the stirring shaft drives the stirring blades to rotate, the movable blade bodies on the stirring blades can move up and down at a high speed in the vertical direction, so that slurry components are fully crushed.

Description

technical field [0001] The invention relates to geotechnical engineering equipment, in particular to mud stirring equipment for geotechnical engineering. Background technique [0002] Geotechnical engineering mainly studies the engineering characteristics of soil constituents. In geotechnical engineering construction, the use of mixing piles is an effective construction form for soft foundation treatment. The construction of mixing piles uses cement as the main agent of the curing agent, and the use of mixing pile machines The cement (slurry) is sprayed into the soil and fully stirred to cause a series of physical and chemical reactions between the cement and the soil, which hardens the soft soil and improves the strength of the foundation. [0003] When the existing stirring pile machine for geotechnical engineering is working, due to the relatively low speed of the stirring shaft, it is difficult for the stirring blades to fully break up the mud components. There are soil...

Problems solved by technology

[0003] When the existing stirring pile machine for geotechnical engineering is working, due to the relatively low speed of the stirring shaft, it is difficult for the stirring blades to fully break up the mud components. There are soil particles (see e.g. figure 1 The cross-section schematic diagram of the prior art mixing pile pile), the existence of soil particles will directly affect the structural tightness of the mixing pile, resulting in a decrease in its strength
