Pile foundation engineering cast-in-situ bored pile anti-pollution construction method

Abstract

The invention discloses a pile foundation engineering cast-in-situ bored pile anti-pollution construction method. The pile foundation engineering cast-in-situ bored pile anti-pollution construction method comprises the steps that a mud pit is arranged on one side of a pile hole of a cast-in-situ bored pile, a steel pile casing is arranged at an opening of the pile hole, a mud discharging opening connected with the steel pile casing and a pipe containing groove of the mud pit are excavated, a mud discharging pipe is arranged in the pipe containing groove, and the mud discharging pipe is connected with the mud discharging opening and the mud pit, a mud pump is arranged in the mud pit, the mud pump and a pile hole are connected through a mud feeding pipe, the mud pump is started, and a punching pile machine is adopted for performing cast-in-situ bored pile construction. When the punching pile machine is used for performing cast-in-situ bored pile construction, mud in direct circulation of a pile foundation is pressed out of the mud discharging opening of the steel casing and then discharged into the mud pit through the mud discharging pipe, the mud discharging pipe is limited in the pipe containing groove, the mud is conveyed in the mud discharging pipe, and environmental pollution caused by overflowing of the mud in direct circulation of the pile foundation can be prevented.

Description

Technical field [0001] The invention relates to the field of pile foundation engineering, and in particular to an anti-pollution construction method for bored cast-in-place piles in pile foundation engineering. Background technique [0002] During the construction of pile foundations such as highways, railways, bridges, etc., due to the high requirements of environmental protection, safety and environmental protection measures are often required during the construction process, especially the construction of pile foundations near rivers and traffic roads. When constructing bored piles in a conventional on-site environment, a mud pool is often excavated nearby, and the mud pressure outlet of the pile foundation is arbitrarily discharged into the mud pool. The mud overflows and pollutes the river or road. During the impact of the percussion drill, the Mud splashes. Mud overflow and mud splashing cause chaos on the working surface and cause serious environmental pollution to t...
