A device for removing slag at the bottom of cast-in-situ piles and a method for removing slag using the device

Abstract

The invention discloses filling pile bottom dreg cleaning equipment and a dreg cleaning method adopting the same, and relates to the technical field of building construction. The dreg cleaning equipment comprises a dreg storage pool, a conical barrel and a check plate, wherein the dreg storage pool comprises an outer cylindrical barrel; an upper opening of the conical barrel is small, and a lower opening of the conical barrel is big; the check plate is hinged to one side of the upper opening of the conical barrel and can cover the upper opening of the conical barrel; the whole conical barrel is arranged on the inner side of the outer barrel of the dreg storage pool; and the dreg storage pool further comprises at least one layer of dreg storage board capable of being positioned between the inner wall of the outer barrel and the outer wall of the conical barrel. The dreg cleaning method adopting the filling pile bottom dreg cleaning equipment comprises the following steps that the dreg cleaning equipment is hoisted to the bottom of a filling pile hole; the check plate is automatically opened under the action of buoyancy, and dregs at the hole bottom flow to the position above the dreg storage pool through the upper opening of the conical barrel; the dreg cleaning equipment is subjected to standing for five to eight minutes; the dreg cleaning equipment is slowly lifted upwards, the dregs sink on a dreg storage plate of the dreg storage pool, and the dregs deposited in the dreg storage pool are cleaned up; and the above steps are executed again until the dregs at the bottom of the filling pile hole are cleaned up thoroughly.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device for removing slag at the bottom of cast-in-situ piles and a method for removing slag using the device. Background technique [0002] The cast-in-situ piles in the current pile foundation engineering, whether they are mechanically or manually drilled, inevitably form a large amount of sediment at the bottom of the pile hole due to technological reasons, and the cleaning effect of the bottom of the hole directly affects the pile foundation engineering. The quality of slag removal is self-evident. At present, the cleaning methods at the bottom of the hole: one is to use the water pipe to inject water or compressed air into the bottom of the hole, and the sediment will be taken out of the pile hole through the action of water and compressed air to achieve the purpose of cleaning the bottom of the pile; Use the slag canister to dredge the sediment at the bottom...

AI Technical Summary

Problems solved by technology

The above two common methods have the following disadvantages: 1. Judging the cleaning effect of the sediment based on the observation of the outflowing mud and measuring the rope, it is difficult to make an accurate and intuitive judgment, and the cleaning quality of the sediment at the bottom of the hole cannot be guaranteed. The cleaning effect is difficult to reflect intuitively; 2. The above method uses air and water to flow the sediment out of the pile hole with the mud, causing serious pollution, and the subsequent mud removal is not conducive to the construction period and cost control; 3. The large amount of water and electricity increases the construction cost
