Embodiment 1

[0020] like Figure 1~2 As shown, an inspection well for improving the sealing performance of the interface has a vertical socket 1 that is hollow inside, and a well seat connecting port 1-1 for communicating with a branch pipe 2 is provided on the outer wall of the vertical socket 1, and the well seat The connecting port 1-1 communicates with the inner cavity of the vertical socket 1 of the well seat, and the connecting port 1-1 of the well seat is provided with five first reinforcing ribs 1-2 in the circumferential section of the outer ring, and the first reinforcing ribs 1-2 are connected to the inner cavity of the well seat. The well base connecting port 1-1 is distributed vertically in the axial direction, and the outer ring of the interface end of the branch pipe 2 is provided with four second reinforcing ribs 2-2 in the circumferential direction, and the inner and outer diameters of the well seat connecting port 1-1 and the branch pipe 2 are the same. The first reinforc...

Embodiment 2

[0022] like image 3 As shown, an inspection well for improving the sealing performance of the interface has a vertical socket 1 that is hollow inside, and a well seat connecting port 1-1 for communicating with a branch pipe 2 is provided on the outer wall of the vertical socket 1, and the well seat The connecting port 1-1 communicates with the inner cavity of the vertical socket 1 of the well seat, and the connecting port 1-1 of the well seat is provided with five first reinforcing ribs 1-2 in the circumferential section of the outer ring, and the first reinforcing ribs 1-2 are connected to the inner cavity of the well seat. The well seat connecting port 1-1 is distributed vertically in the axial direction, and two rubber rings 1-5 for sealing and stabilizing are arranged between the five first reinforcing ribs 1-2 on the outer ring of the well seat connecting port 1-1 , the end of the branch pipe 2 interface connected to the well seat connection port 1-1 has a flared section...

Abstract

The invention relates to the technical field of pipe fittings, in particular to a manhole for improving joint sealing performance, which is provided with a hollow vertical socket. Manhole base pipe joints communicated with branch pipes are arranged on the outer wall of the vertical socket, the manhole base pipe joints are communicated with an inner cavity of the manhole base vertical socket, and at least one reinforcing rib is arranged on the periphery of the outer ring of each manhole base pipe joint. A branch pipe which is connected with the manhole is connected with a pipe through a rubber ring and a hoop, and the pipe is the same as the branch pipe in structure and outer diameter, and the branch pipe can also be inserted into a flared section of a corresponding branch pipe joint through the corresponding manhole base pipe joint. The reinforcing ribs are added to the outer walls of the pipe joints of the manhole, and accordingly the thickness of the pipe wall is enhanced effectively, compression strength of the pipe wall is enhanced, the sealing performance of sealing positions of the joints is enhanced, the joints are less prone to corrosion, the service life of the pipe is prolonged effectively, and the technical problem of connection of glass-reinforced plastic pipes with the plastic manhole is solved.

Description

technical field [0001] The invention relates to the technical field of pipeline fittings, in particular to an inspection well for improving the sealing performance of a joint. Background technique [0002] Inspection wells are suitable for rainwater discharge pipelines and auxiliary structures for maintenance workers to check and eliminate foreign objects. At present, various pipelines such as rainwater, sewage, and water supply need to be buried in the lower part of urban roads. There are corresponding inspection wells on the road surface, and whether the connection between the inspection well and the water inlet and outlet pipes is Sealing is related to the safety of pipeline circulation. The conventional connection between the inspection well and the pipeline includes the use of glue, the pipeline is directly inserted into the socket of the inspection well, and the connection is made with glue. Although this method can be firmly connected for a while , but in the process...
