A Pile Foundation Hole Forming Method with Efficient Recycling of Mud

Abstract

The invention relates to the field of pile machine mud treatment, in particular to a pile foundation hole forming method capable of efficiently recycling mud. The heightened steel casing is buried on the pile position, so that the upper part of the heightened steel casing is exposed to the ground. After the drill pipe is drilled into place, the slag mud mixture is discharged to the mud treatment through the connection pipe of the slag mud mixture on the heightened steel casing. In the sedimentation area of ​​the tank, the mud in the slag-slurry mixture can overflow to the mud area for further sedimentation through the overflow port between the sedimentation area and the mud area of ​​the mud treatment tank, and the mud in the mud area of ​​the mud treatment tank can pass through the mud output interface. Proceed to the settling zone of the next mud treatment tank and repeat the above. The invention solves the problem of difficult mud treatment in the traditional pile driving operation, avoids environmental pollution, and avoids the problem of wasting water resources, makes the best use of the mud material generated in the pile driving operation, and reduces the labor of on-site operation. strength.

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
