Detailed Description
As shown in fig. 1-3, the novel sealing interface for the reinforced concrete drain pipe comprises a pipe body 2, wherein one end of the pipe body 2 is provided with a socket 1, the other end of the pipe body 2 is provided with a socket 5, and the socket 1 and the socket 5 are used for realizing butt joint and sealing between one section of pipeline and the other section of pipeline; two rubber ring grooves 6 are formed in the socket 5 end of the pipe body 2, sealing rings 3 are arranged in the rubber ring grooves 6, two sealing surfaces with the same sealing effect are formed by the two sealing rings 3, and the sealing pressure of each sealing surface is not lower than 0.6 Mpa; and a middle rib is formed between the two rubber ring grooves 6, a water through hole 4 is formed in the middle rib, and interface sealing detection is performed by using the water through hole 4.
As an optional implementation mode, two water through holes 4 are symmetrically arranged on the middle rib along the axis of the pipe body 2, a hydrostatic testing machine can be connected to introduce water into the water through holes 4, a closed cavity formed by two rubber sealing rings, the surface of the middle rib and the working surface of the socket 1 is filled with the water, and interface sealing detection is carried out.
As an alternative embodiment, the outer diameter of the socket 5 is smaller than the inner diameter of the socket 1, a reasonable gap between the socket 1 and the socket 5 enables the sealing ring 3 to be reasonably compressed, the interface is sealed through resistance generated by compression deformation, and the flexible corner with a certain angle can be formed on the basis of sealing.
As an alternative embodiment, the pipe body 2 is a reinforced concrete pipe body, and when the socket 1 is used for jacking construction, a steel socket as shown in fig. 6 and 7 may be used.
As an alternative embodiment, the sealing ring 3 is a rubber sealing ring, the rubber sealing ring is made of natural rubber or synthetic rubber, and the cross-sectional size and the diameter of the rubber sealing ring are determined by the sealing design.
As an alternative embodiment, when the inner diameter of the pipe body 2 is larger than 1200mm, the drain pipe sealing interface with the structure shown in fig. 1 and 3 is adopted; when the inner diameter of the pipe body 2 is not more than 1200mm, the drain pipe sealing interface of the structure shown in fig. 4 and 5 is adopted.
The installation process of the invention is as follows:
firstly, the sealing ring 3 is placed in a rubber ring groove 6 of the socket 5, and a layer of lubricating oil is coated on the sealing surface of the socket 1 and the socket 5 so as to reduce the friction force during insertion; then the end of the pipe socket 5 to be installed is inserted into the end of the socket 1, at the moment, the sealing ring 3 is limited by a gap between the socket 1 and the socket 5 to generate compression deformation, the sealing ring 3 deforms by itself but clings to the working surfaces of the socket 1 and the socket 5 to form a sealing surface, so that the sealing effect is achieved; one of the limber holes 4 is connected with a water pressure testing machine, water enters from the limber hole 4, and the other limber hole 4 exhausts and drains water; when drainage is started, the water through hole 4 for drainage is sealed by the bolt, the hydraulic press continues to pressurize, the hydraulic test of the interface is realized, the effect of interface sealing detection is achieved, and the installation quality is guaranteed.
