Cleaning device and cleaning method for concrete conduit

Abstract

The invention discloses a cleaning device and a cleaning method for a concrete conduit; the cleaning device comprises a water flow injector, an annular outer pipe and an annular inner pipe; the annular inner pipe is arranged in the annular outer pipe; the annular outer pipe and the annular inner pipe are hollow annular pipes; the inner walls of the annular outer pipe and the annular inner pipe areevenly arranged with a plurality of water spray holes; the top walls of the annular outer pipe and the annular inner pipe are respectively provided with water inlets; the water flow injector comprises a pressurized water inlet, a water inlet pipe, a pumping device, a water flow outlet and a water outlet pipe which are connected successively; the pumping device is used for increasing the flow rateof the water, and the water outlet pipe is connected to the inlet pipe on the annular outer pipe or the annular inner pipe; when cleaning the concrete conduit: the water flow injector is connected with the water source by a water pipe. With simple operation, the cleaning device and method provided by the invention can liberate the labor, improve the work efficiency, realize the mechanized construction, shorten the construction period and reduce the project cost. With a small floor area and strong mobility, the cleaning device can be changed according to the construction site.

Description

technical field [0001] The invention belongs to the technical field of concrete conduit cleaning, and in particular relates to a concrete conduit cleaning device and a concrete conduit cleaning method. Background technique [0002] In the field of pile foundation construction, the conduit is an essential tool in the concrete pouring process. After the concrete pouring is completed, the inner and outer walls of the conduit must be cleaned to ensure that the inner and outer walls of the conduit are smooth and smooth. If the cleaning is not clean and there is residual mud residue on the conduit wall, then the conduit will be blocked during the concrete pouring process, the concrete pouring will not be dense, and further serious situations such as broken piles will occur, which will affect the quality of the piles and endanger the safety of the upper structure. Therefore, the cleaning efficiency and quality of the catheter will slow down the construction progress, and in severe...

AI Technical Summary

Problems solved by technology

If the cleaning is not clean and there is residual sludge on the conduit wall, the conduit will be blocked during the concrete pouring process, the concrete pouring will not be dense, and further serious situations such as broken piles will occur, which will affect the quality of the pile and endanger the safety of the upper structure.

Therefore, the cleaning efficiency and quality of the conduits will slow down the construction progress, and in severe cases, affect the construction quality, resulting in rework and delays, increasing time and labor costs, reducing efficiency, and wasting resources.

At present, the catheter cleaning work is to pull out the catheter and manually spray water to clean the inner and outer walls of the catheter, which will cause a lot of waste of human resources

At the same time, during the cleaning process of additional occupation of the construction site, the water after cleaning the conduits cannot be effectively discharged or disposed of in time, resulting in muddy construction sites, affecting the construction order on site, further affecting the development of other construction processes, slowing down the construction progress, and indirectly causing time costs. increase

Especially in the case of relatively intensive construction period or long pile length, if a large number of conduits are piled up, if they cannot be cleaned in time, the construction progress will be delayed and the construction period will be extended

At present, the research on concrete conduit cleaning device is still blank, so it is necessary to realize the mechanization of conduit cleaning
