Pile foundation pore-forming method capable of efficiently recycling slurry

Abstract

The invention relates to the field of pile machine slurry treatment, and specifically relates to a pile foundation pore-forming method capable of efficiently recycling the slurry. The pile foundationpore-forming method is characterized in that a heightened steel casing is buried at the pile position, the upper part of the heightened steel casing is enabled to be exposed out of the ground, a muck-slurry mixture is discharged to a sediment zone of a slurry processing box through a muck-slurry mixture communicating pipe on the heightened steel casing after a drilling rod drills in place, the slurry in the muck-slurry mixture can overflow to a slurry zone for further sediment through an overflow mouth between the sediment zone and the slurry zone of the slurry processing box, the slurry in the slurry zone of the slurry processing case can get into the sediment zone of the next slurry processing box through a slurry output interface, and the above process is repeated. The pile foundation pore-forming method solves a problem of difficult slurry treatment in the traditional pile machine operation, avoids environment pollution, also avoids a problem of water resource waste, makes the bestuse of the slurry produced in the pile machine operation and reduces the labor intensity of the field operation.

Description

technical field [0001] The invention relates to the field of pile driver mud treatment, in particular to a pile foundation hole forming method in which mud can be efficiently recycled. Background technique [0002] The application of bored piles in my country began in the early 1960s, and was first used in bridge and port construction. In April 1965, the Ministry of Communications held a technical appraisal meeting for bored piles in Henan, which was recognized as a major technological innovation and became the preferred form of foundations for highway and railway bridges, and became popular all over the country. [0003] The positive circulation slag discharge method is that during the drilling process, the drill bit processes the crushed mud into a slurry, and then uses the mud pump to send high-pressure mud, and sends the mud to the bottom of the drill bit through the center pipe of the drilling rig. mixed with crushed mud and slag, carrying the soil to move upward along...

AI Technical Summary

Problems solved by technology

[0004] Conventional mud sedimentation tanks need to be excavated on site, which not only requires labor and time to remove the earthwork during excavation, but also needs to be backfilled when the construction is completed, and it also causes damage to the ground and causes various environmental pollution; during the construction process A large amount of mud is produced, the treatment is difficult, and the direct discharge pollution is serious
