Bored pile mud sedimentation filter device and its construction method

Abstract

The present invention relates to a cast-in-situ bored pile slurry deposition filtering apparatus and a construction method, the cast-in-situ bored pile slurry deposition filtering apparatus includes a four-stage hydraulic pressure altitude difference precipitation system and a mud and sand filtration system, the four-stage hydraulic pressure altitude difference precipitation system successively comprises, from the inside to the outside, a four-stage clean water pool, a three-stage purification pool, secondary-stage outward transport pools, desilting platforms and first-stage desilting pools, the first-stage desilting pools are respectively arranged in the four corners of the four-stage hydraulic pressure altitude difference precipitation system, the four-stage clean water pool is in the middle of the four-stage hydraulic pressure altitude difference precipitation system, the four-stage clean water pool is surrounded by the three-stage purification pool, the secondary-stage outward transport pools are respectively arranged in the middle parts of one pair of opposite sides of the four-stage hydraulic pressure altitude difference precipitation system, the desilting platforms are respectively arranged in the middle parts of the other pair of opposite sides of the four-stage hydraulic pressure altitude difference precipitation system, the mud and sand filtration system comprises support frames, a filter net and anti-clogging wire ropes, the support frames are interposed around purification pools of the four-stage hydraulic pressure altitude difference precipitation system in appropriate intervals, the filter net is fixed on the support frames, and the anti-clogging wire ropes are fixed in the middle of an interlayer of the filter net. The cast-in-situ bored pile slurry deposition filtering apparatus reduces the slurry processing cost.

Description

technical field [0001] The invention belongs to the technical field of pile foundation engineering construction, in particular to a mud sedimentation filter device for bored cast-in-place piles and a construction method thereof. Background technique [0002] Bored piles with mud wall protection are widely used in pile foundation engineering because of their good stratum adaptability, flexible pile diameter and pile length, and large single pile bearing capacity. However, the problems of high pollution and high processing cost of circulating mud have not been well resolved so far, which limits its further development and application. [0003] Mud control is a particularly critical link in the construction of bored cast-in-situ piles with mud retaining walls, and it has a decisive impact on the construction progress, quality and cost of cast-in-situ piles. In the actual construction process, due to technological requirements, the amount of mud produced by a single pile is as ...
