Pump pipe washing structure and method

Abstract

The invention provides a pump pipe washing structure. The pump pipe washing structure comprises an air and water pipe, a valve and a pump pipe, wherein the valve comprises a valve body and a valve element; two ports of the valve body are correspondingly connected to the first end of the air and water pipe and a connecting hole in the outer wall of the pump pipe; and the valve element fits an emptycavity in the valve body and is used for controlling the connection and disconnection of the two ports of the valve body. The pump pipe washing structure further comprises a pump pipe support for supporting the pump pipe. The invention also provides a washing method for sequentially washing a first pipeline and a second pipeline. The whole pump pipe washing structure is simple; few spare parts are used; the pump pipe is connected to the air and water pipe at an elbow seat through the valve; the valve element is unscrewed, and the valve is opened to pump the pump pipe; the operation is convenient; the problem of blockage of the pump pipe is effectively solved; an air pipe and a water pipe are synchronously connected to the air and water pipe through a T joint, so that water current pressure is increased, and the washing efficiency is improved; the first pipeline and the second pipeline are correspondingly provided with stop valves; a sectional washing method is carried out; water flowsin one direction, so that the pipeline can be quickly cleanly washed; and the washing quality is obviously improved.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a pump tube cleaning structure and a cleaning method. Background technique [0002] Tunnel lining trolley is a non-standard product specially designed and manufactured for concrete lining of different cross-sectional sizes such as tunnels and culverts. It is characterized by a motor-driven traveling mechanism to drive the trolley to travel, and uses hydraulic cylinders and screw jacks to adjust the formwork in place and close the formwork. , the surface finish of the lining is high, and the lining speed is fast. It has the advantages of low cost, reliable structure, convenient operation, fast lining speed and good tunnel forming surface. [0003] During the lining process of the trolley, the concrete is transported by the pump through the pump pipe, and poured layer by layer and window by window through the distributor. Due to the characteristics of concrete, i...
