Cleaning device for pile bottom sediment of cast-in-place concrete pile

Abstract

The invention discloses a cleaning device for a pile bottom sediment of a cast-in-place concrete pile. The device includes a drilling machine, a pressure water pump, and a sediment cleaning device; the drilling machine is used for driving a drill rod into a concrete pile body, and the drill rod is installed in sections; the pressure water pump is connected into the drilling machine through a waterpipe and communicates with the drill rod; and the sediment cleaning device includes a core pipe and a hole cleaning device, the top end of the core pipe is connected to the drill rod, a screwed jointof the top end of the hole cleaning device is screwed to the bottom end of the core pipe, a hollow pipe body is disposed on the hole cleaning device, the bottom end of the hollow pipe body is provided with a hole, and the hole cleaning device communicates with the drill rod. The device can pulverize the sediment at the bottom of the pile, the sediment is driven in by employing high-pressure circulating water from the drilling machine, flows from the drill rod into a core pipe connector, and discharges from the water outlets at both ends of a drain pipe, a sediment layer is flushed, and the sediment flows out of the concrete pile body together with water along a gap of the outer edge of the drill rod. The device is simple in structure, is convenient to operate, and is good in effect.

Description

technical field [0001] The invention belongs to the technical field of concrete pouring pile construction, and in particular relates to a device for cleaning sediment at the bottom of concrete pouring piles. Background technique [0002] Concrete pouring piles, which are widely used in buildings and structures, are supporting components that transmit the load of the superstructure to the rock and soil foundation, and play a vital role in the safety of engineering structures. The foundation pile project is a concealed project; after the pile body defects and the pile bottom sediment are found to be too thick, the foundation pile must be treated with reinforcement and other methods before it can continue to be used; however, before the treatment, a large amount of pile bottom sediment must be removed before proceeding Pile body reinforcement and other treatment work, otherwise the treatment will not achieve the expected effect. Based on the summary of long-term engineering pr...
