How to deal with piling mud?

How to deal with piling mud? Generally speaking, how do people in the construction industry in China deal with piling mud? What are the basic construction techniques? The following are the relevant contents of professional architectural terms in the piling process compiled by Zhong Da Consulting Bianxiao Company, and the basic situation is as follows:

Piling refers to driving a pile into the ground to make the foundation of a building firm. Piling training is an ideal choice for rural surplus labor transfer training, technical training for construction enterprises and re-employment training for laid-off workers. At present, how do construction enterprises in China deal with piling mud treatment, and what is the basic construction technology? The basic overview is as follows:

The disposal of sludge in urban construction has always been a difficult problem that puzzles engineering construction. Piling mud is a kind of suspended liquid containing a certain amount of fine mud particles in water, which has a certain viscosity and is not easy to delaminate after standing for a long time. Building piling (pile foundation) technology is the frontier technology in non-excavation mode. As one of the main systems of mud piling (pile foundation), mud treatment system directly affects the construction progress and quality. One of the outstanding problems in the application of this technology is mud treatment and reasonable application.

Treatment method of piling mud:

The sludge discharged from the sludge discharge pipe after drilling by rotary drilling rig is purified by horizontal spiral centrifuge. If the sand content of the treated sludge meets the requirements, it can be directly discharged into the sedimentation tank for overflow sedimentation; Otherwise, it can be further treated by the treatment equipment of the dosing system, and then discharged into the sedimentation tank for overflow sedimentation. After treatment and batching, the screened ballast is transported to the designated spoil ground for stacking. After the mud overflows into the regulating tank, if the mud amount is too much, it can be discharged into the slurry abandonment tank for storage. When the mud amount exceeds the capacity of the slurry abandonment tank, it can be pumped to a nearby transport vehicle and transported to the slurry abandonment field. If the amount of mud can't meet the demand, you can use the mud pump to make and replenish the mud manually. When the mud concentration in the regulating tank meets the requirements, it should be directly pumped to the rotary drilling rig by the mud pump; If the mud concentration is too strong, add water to dilute it; If the mud concentration is too low, adjust the mud to increase the mud concentration, and then pump it to the rotary drilling rig. According to the flow of piling mud, it is treated by mud discharging equipment first, and then discharged into the sedimentation tank for overflow. According to the requirements of slag slurry treatment capacity of pile driving slurry treatment system, different types of horizontal spiral centrifuges can be selected, and the purification and sand removal rate is high, which can reach more than 95%. The pile driving mud treatment system of horizontal spiral centrifuge has the advantages of low failure rate, convenient installation, use and maintenance, good use effect and high separation efficiency, and can adapt to various pile driving (pile foundation) construction technologies in different strata. The motor has advanced power structure, strong universality, reliable operation and convenient disassembly and maintenance. Ensure the long-term normal operation of the equipment. The electrical control adopts frequency conversion starting control system (PLC can realize full automatic control), which has simple wiring, strong anti-interference ability and convenient maintenance. Fully meet the normal driving capacity of rotary drilling rig and improve production efficiency. The treated mud has high quality and the sand content is less than 5%. Because the water content of the treated soil and sand is less than 30%, the discharge is greatly reduced, and the transportation is convenient, which saves the transportation cost, ensures the smooth progress of the piling project, avoids the environmental pollution caused by the problem of mud discharge by piling, and is beneficial to environmental protection.
