Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated pipe tight pipe installation technical field, concretely is a kind of tight pipe device of HDPE double-wall corrugated pipe. BACKGROUND

[0002] In the installation process of HDPE double-wall corrugated pipe, tight pipe usually refers to the operation of tightly connecting the socket and spigot of pipe material to ensure the sealing and stability of pipeline connection. Generally speaking, for DN400 and below pipelines, one person usually uses cotton yarn to hang the spigot of the installed pipeline, and the other person uses a long pry bar to insert obliquely into the foundation and resist the cross baffle at the center position of the pipe end, and then slowly inserts the pipe into the socket of the pipeline to be installed to the predetermined position. The method is used to realize tight pipe. For DN400 and above pipelines, two hand-operated hoists can be used to pull the pipe joint into position. When the interface is folded, the hand-operated hoists on both sides of the pipe joint should be pulled synchronously to ensure that the rubber sealing ring is correctly positioned without distortion or falling off. In addition, some special tools can be used to assist in tight pipe operation, such as corrugated pipe tensioner, which can save installation time and labor cost, and conveniently and quickly connect the pipeline tightly.

[0003] In the installation operation of HDPE double-wall corrugated pipe, the adjacent pipe heads often face the difficult problem of precise alignment. Under the traditional method, manual alignment not only consumes a lot of manpower and time, and the efficiency is extremely low, and the precision is difficult to guarantee, which leads to many difficulties in subsequent tight pipe fixing operation, and easily causes poor sealing and insufficient stability of pipeline connection, which greatly affects the engineering quality and progress.
