Problems solved by technology

[0002] In the existing technology, the HDPE plastic-steel winding pipe stainless steel clamp interface that has been constructed has been found. After the stainless steel clamp is tightened, the stainless steel clamp will occur under a large temperature difference in a day, that is, in the morning, middle, evening, and sunny or cloudy days. Loosening, that is, tightening when the daily temperature is high, loosening when the daily temperature is low, and leakage occurs

Embodiment 1

[0065] Example 1: An anti-seepage construction method for the joint of HDPE plastic-steel winding pipe

[0066] S1, the connection between pipe joints and joints of the same pipe diameter, refer to figure 1 ,

[0067] S101, setting up a sunshade at the construction site.

[0068] S102, under the awning, take two pipes 1 with the same diameter. There are several annular grooves 3 arranged linearly on the pipes 1, and respectively clamp the circular rubber and plastic sealing rings 21 in the annular ring at one end of the interface of the pipe 1. Shaped rubber plastic sealing ring 21 just in time conflicts with annular ring two sidewalls;

[0069] S103, wrapping a rubber sleeve 4 on the outer surface of one of the pipes 1 . The length of the rubber sleeve 4 inserted into the pipeline 1 is half of the total length of the rubber sleeve 4 and wraps the circular rubber plastic sealing ring 21;

[0070] S104, open the rubber sleeve 4 that is not inserted into the pipe 1 outwards ...

Embodiment 2

[0085] Example 2: An anti-seepage construction method for the connection of HDPE plastic-steel winding pipes. The difference from Example 1 is that the anti-seepage construction method includes the butt joint of pipe joints with different pipe diameters. Refer to image 3 and Figure 4 ,Specific steps are as follows,

[0086] S301, take two pipes 1 with the same diameter and an annular gasket 13 whose diameter is larger than that of the pipe 1. The head of the pipe 1 has an annular elastic joint 16. The diameter of the elastic joint 16 is larger than the diameter of the pipe 1. The inner wall of the elastic joint 16 has an inner thread; the outer wall of the tail of the pipeline 1 has external threads; the annular gasket 13 is provided with an annular stopper 14 equal in diameter to the elastic joint 16, and the annular stopper 14 has a groove 15; the annular gasket 13 has an elastic joint 16 The outer thread matched with the inner thread, the ring gasket 13 has an inner thre...

Abstract

The invention discloses an anti-seepage construction method of a connector of an HDPE (high-density polyethylene) plastic steel winding pipe. The anti-seepage construction method comprises the following steps of (S01) preparing two to-be-connected HDPE plastic steel winding pipes at low temperature; (S02) respectively sleeving elastic fillers which are matched with circular grooves in the circular grooves of outer rings of the two HDPE plastic steel winding pipes; (S03) wrapping rubber sleeves on the outer rings of the two HDPE plastic steel winding pipes, wherein the length of the rubber sleeves in pipelines is set, so that the elastic fillers can be respectively wrapped; (S04) wrapping middle cushion layers on the rubber sleeves; and (S05) wrapping stainless steel hoops on outer rings of the middle cushion layers, and tightening the stainless steel hoops. By adopting the technical scheme, the elastic fillers are arranged in the outer rings of the pipelines, the contact area between the pipelines and the rubber sleeves is greatly increased by the elastic fillers, and then the middle cushion layers are wrapped on the rubber sleeves and are tightened by tightening the outside stainless steel hoops, so that the sealing performance between connectors is good.

Description

technical field [0001] The invention relates to the field of pipeline construction, in particular to an anti-seepage construction method for a connection port of an HDPE plastic-steel winding pipe. Background technique [0002] In the existing technology, the HDPE plastic-steel winding pipe stainless steel clamp interface that has been constructed has been found. After the stainless steel clamp is tightened, the stainless steel clamp will occur under a large temperature difference in a day, that is, in the morning, middle, evening, and sunny or cloudy days. Loosening, that is, tightening when the daily temperature is high, and loosening after the daily temperature is lowered, and leakage occurs. Contents of the invention [0003] The purpose of the present invention is to provide an anti-seepage construction method for the connection of HDPE plastic-steel winding pipe, which has the advantages of better improving the sealing performance of the pipe connection and improving...
