Problems solved by technology

When filling the linseed, the linseed is often not well fixed in the casing, and often slips, resulting in poor sealing; when the temperature is high, the waterproof coating paste will melt, resulting in the loss of the waterproof coating paste
These problems will cause leakage around the pipe

Embodiment 1

[0019] Such as figure 1 As shown, this embodiment provides a waterproof casing, which is composed of a casing connection part and a waterproof part. The sleeve connection part is formed by fixedly socketing two-stage pipe bodies. The port of the first-stage pipe body 5 with a smaller diameter is inside the second-stage pipe body 6 with a larger diameter. The end of the first pipe body The outer side of the head is provided with an inclined surface that gradually becomes larger from the end to the inside, and the inner side of the second pipe body is provided with an inclined surface whose inner diameter gradually becomes larger from the end to the inside. The inclined surfaces are connected with each other. The first pipe body and the second pipe body are tightly fitted and connected through plastic deformation. A pipe body accommodation space is formed between the first-stage pipe body 5 and the second-stage pipe body 6 , and a fixed platform 4 is formed at the port of the ...

Embodiment 2

[0021] The difference between embodiment 2 and embodiment 1 is that the contact surface between the first pipe body and the second pipe body in embodiment 2 is not provided with an inclined surface, and the outer diameter of the first pipe body is slightly smaller than the inner diameter of the second pipe body. Large, the two are connected by tight fit through plastic deformation. The fixed part is made of linseed 3, the oil blocking part is made of dry lime, and the waterproof coating is composed of waterproof oil, wherein the linseed 3 is directly in contact with the fixed table 4, the dry ash 2 is set on the linseed 3, and the dry lime is A waterproof coating is set, and linseed 3 and dry lime are arranged in the accommodation space of the pipe body, 80% of the waterproof coating is located in the accommodation space of the pipe body, and 20% is located at the end of the solute space of the pipe body.

Abstract

The invention discloses waterproof facilities for engineering construction, and particularly relates to a waterproof casing. The waterproof casing comprises a casing body and a waterproof sealing material. The casing body is formed by two stages of tube bodies which are in fixed cup joint, and an end opening of the first-stage tube body with the small caliber forms a fixed station in the second-stage tube body with the big caliber. Due to the fact that waterproof coating paste is smeared on the outside of dry ash, when the temperature is high, the waterproof coating paste can be prevented from running off due to fusion, and therefore leakage is prevented.

Description

technical field [0001] The invention relates to a waterproof facility for engineering construction, in particular to a waterproof casing. Background technique [0002] In engineering construction, the traditional waterproof casing usually uses a single-stage steel pipe as the casing, directly filled with linoleum, and finally coated with waterproof coating paste. When filling the linseed, the linseed is often not well fixed in the casing, and often slips, resulting in poor sealing; when the temperature is high, the waterproof coating paste will melt, and then cause the loss of the waterproof coating paste. These problems will cause leakage around the pipe. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof casing, so that when filling the waterproof sealing material, the waterproof sealing material can be better fixed in the casing. [0004] Technical scheme of the present invention is as follows: [0005] A waterproof cas...
