Embodiment Construction

[0031] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0032] Tool introduction:

[0033] Such as figure 1 , the pipeline has a socket 13 and a socket 14, and the external diameter of the socket 14 of the pipeline is smaller than the internal diameter of the socket 13.

[0034] Such as Figure 4 , The clamp 2 is formed by butt jointing of two connecting rings 21 whose radian is less than π, the inner diameter of the connecting ring 21 is the same as the diameter of the middle part of the pipe, and the bolt 23 passes through the extensions 22 of the two connecting rings 21 and connects the nut 24 at the same time.

[0035] Such as image 3 , the len...

Abstract

The invention discloses a sewage pipeline laying process which sequentially comprises the steps of excavating a tunnel, laying a base, laying pipelines and refilling. According to pipeline laying, pipeline connection is carried out by adopting a sequential butt-joint way, the previous pipeline is firstly fixed before the next pipeline is laid, and each pipeline is provided with a socket and a spigot. The pipeline butt-joint way comprises the following steps of (1) excavating a working pit at the butt-joint part of a fixed pipeline and a pipeline to be installed; (2) installing a push plate on the socket part of the pipeline to be installed, wherein the push plate is abutted against the end surface of the socket of the pipeline to be installed; (3) installing a clamping hoop on the outer wall of the fixed pipeline, wherein the inner diameter of the clamping hoop is smaller than the outer diameter of the socket of the pipeline; (4) hanging the pipeline to be installed into the tunnel, aligning axes of the pipeline to be installed and the fixed pipeline, and installing a chain block, wherein the clamping hoop and the push plate are connected to two ends of the chain block; and (5) sleeving a seal ring on the spigot part of the pipeline to be installed, and pulling the chain block so as to enable the spigot of the pipeline to be installed to be inserted into the socket of the fixed pipeline.

Description

technical field [0001] The invention relates to the field of sewage pipeline construction, in particular to a process for laying sewage pipelines. Background technique [0002] The urban pipe network includes water purification pipes and sewage pipes, and the pipes are connected by splicing to form a pipe network. [0003] At present, the way of pipe splicing generally consists of flange connection, butt joint and socket connection. The butt joint is mainly composed of a connecting pipe, two pipes are inserted into the connecting pipe at the same time for butt joint and anti-seepage slurry is laid on the joint. The flange connection is mainly connected through the flange plate at the end of the pipe, which is convenient for subsequent disassembly and assembly. [0004] The socket connection can refer to the reinforced concrete drainage pipeline connection structure disclosed by the announcement number CN202937918U. It is an improved interface method based on the rubber rin...
