Abstract

The invention discloses a recovery and recycling system for waste slurry in formation of rotary-jet piles or stir-jet piles. According to the technical scheme, the waste cement slurry flowing out fromthe opening of a drilled hole is collected and then pumped into a slurry purification device to be filtered, useful cement slurry components obtained after filtration are returned into a cement slurry stirring pool to be re-prepared and stirred to form cement grout meeting design requirements, and the cement grout is pressurized by a high-pressure pump and then jet into the drilled hole again from a drill rod nozzle of a rotary-jetting drill rig or a stir-jetting drill rig through a pipeline system. The recovery and recycling system for the waste slurry in formation of the rotary-jet piles orthe stir-jet piles has the advantages that through filtration and re-preparation of the waste cement slurry, the waste cement slurry is reutilized, the material waste and environmental pollution arereduced, and the cost of transporting the waste cement slurry outwards is reduced.

Description

technical field

[0001] The invention relates to the technical field of jet grouting pile construction, in particular to a waste slurry recycling system of a jet jet pile or a stirring jet pile. Background technique

[0002] The jet grouting method, also known as the jet grouting method, or the jet jet pile for short, is a high-pressure jet grouting method that emerged in the 1970s, and was fully developed and applied throughout the country in the 1980s and 1990s. Practice has proved that this method has a good effect on the treatment of silt, muddy soil, cohesive soil, silt, sandy soil, artificial filling soil and gravel soil.

[0003] The rotary grouting pile uses a drilling rig to drill the rotary grouting pipe and nozzle to the design elevation of the pile bottom, and the pre-prepared grout passes through the high-pressure generating device to make the liquid flow obtain huge energy, and then spray it out from the nozzle near the grouting pipe at high speed , forming a l...
