Description

Technical Field

[0001] The present application relates to the technical field of installation engineering, and in particular to a waterproof structure for a plastic pipe to pass through a pool wall. Background Art

[0002] In modern engineering, plastic pipes have been widely used due to their strong corrosion resistance, light weight, and convenient construction. Especially in the chemical, metallurgical and pharmaceutical industries, plastic pipes are usually required for transportation because the conveying media are mostly corrosive. In order to connect different areas, especially in some pumping stations in these industries, the liquid inlet of the pump often needs to pass through the pool wall. At this time, it is very important to ensure that the crossing point of the pipeline is sealed and waterproof.

[0003] Traditional cast iron pipes and steel pipes are usually installed through the pool wall casing waterproofing with hard tools such as iron brazing. The flexible nature of plastic pipes determines their difference from cast iron pipes and steel pipes. At present, there is no specific method for waterproofing plastic pipes through the pool wall casing. Today, when plastic pipes are widely used, the construction still refers to the method of cast iron pipes and steel pipes through the pool wall casing. There are problems such as easy damage of plastic pipes during installation and poor anti-leakage effect during use, which cannot meet actual needs. Therefore, it is necessary to provide a method structure specifically for waterproofing plastic pipes through the pool wall casing to meet actual needs. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related technology, the present application provides a waterproof structure for a plastic pipe passing through a pool wall, which is used for the installation of plastic pipes. While ensuring the waterproof sealing performance, the sealing, filling and plugging materials used are flexible materials and do not cause damage to the plastic pipe.

[0005] The first aspect of the present application provides a waterproof structure for a plastic pipe passing through a pool wall, comprising: a rigid sleeve, a plastic pipe, a first retaining ring, a second retaining ring, a rubber ring, a filling layer and a sealing layer. The first retaining ring and the second retaining ring are symmetrically installed on both sides of the inner ring of the rigid sleeve, and the first retaining ring and the second retaining ring and the plastic pipe form a groove for installing the rubber ring. The rubber ring is a wedge-shaped structure and limits the first retaining ring and the second retaining ring respectively. A filling hole is opened on the first retaining ring, and a filling layer and a sealing layer are arranged between the rigid sleeve and the plastic pipe along the center to the outside.

[0006] Further, the first retaining ring and the second retaining ring are installed at L / 4 on both sides of the inner ring of the rigid sleeve.

[0007] Furthermore, two rubber rings are provided corresponding to the first retaining ring and the second retaining ring, and the two rubber rings are symmetrically arranged with their large ends facing the inner and outer walls of the pool.

[0008] Furthermore, the filling layer is arranged at the L / 2 position of the gap between the rigid casing and the plastic pipe.

[0009] Furthermore, the sealing layer is arranged at the L / 4 position between the rigid casing and the outer side of the plastic pipe.

[0010] The technical solution provided by this application may have the following beneficial effects:

[0011] The present application provides a waterproof structure for a plastic pipe passing through a pool wall. The sealing, filling and plugging materials used in the structure are all flexible materials, which reduces the damage to the plastic pipe by the traditional installation structure, forms waterproof protection for the plastic pipe passing through the pool wall, has a better anti-leakage effect, and can meet the waterproofing needs.
