the reference numbers in the figures: the inspection well comprises an inspection well body 1, an inclined socket 11 of the inspection well, a horizontal socket 12 of the inspection well, a pipeline 2, a socket end 21 of the pipeline, a socket end 22 of the pipeline, a rubber ring 211 and a rubber pad 3.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, in the inspection well with a socket, an inspection well inclined socket 11 and an inspection well horizontal socket 12 are arranged on an inspection well body 1 and are respectively matched with a pipeline socket end 21 and a pipeline socket end 22;

the outer diameter of the pipeline socket end 21 is gradually increased along the direction close to the pipeline 2, and the pipeline socket end 21 is inserted into the inclined socket 11 of the inspection well;

the pipe female end 22 is connected with the inspection well horizontal socket 12 through a flange.

In the prior art, the connection mode of a pipeline and an inspection well is shown in figure 2, the pipeline and the inspection well are in butt joint and then are plugged by concrete, construction is troublesome, and leakage is easy to occur.

Based on this, the inspection well as shown in fig. 1 is designed, and the butt joint mode is mainly improved. Corresponding to different trends and socket requirements of the pipeline 1, an inclined connection structure which gradually shrinks from outside to inside is designed between the pipeline spigot end 21 of the pipeline 1 and the inclined bell mouth 11 of the inspection well. Meanwhile, the pipeline female end 22 and the inspection well horizontal socket 12 are connected by flanges instead of being only plugged by concrete. Therefore, no matter which end of the pipeline 1 is connected with the inspection well, the pipeline can be connected more tightly, and leakage is effectively prevented. In addition, by adopting the splicing mode, the whole construction is more convenient, and the construction efficiency is improved.

In an embodiment, the manhole body 1 is a square precast concrete manhole, and two opposite side surfaces of the manhole body are respectively provided with a manhole inclined socket 11 and a manhole horizontal socket 12. As shown in the longitudinal section of fig. 1, the top of the pipe is a manhole cover, which is suitable for municipal pipe network, and two ends of the pipe are respectively connected with different ends of two pipes 1. Both sides of the inspection well inclined socket can be designed into the form of the inspection well inclined socket 11 according to actual requirements. The inspection well body 1 can be in different forms such as tee joint, cross, and the quantity and the position of its bell and spigot all can rationally set up as required. Of course, the design of the socket can be also pushed to a round concrete inspection well or a plastic inspection well.

In one embodiment, as shown in fig. 3, which is a cross-sectional view of a pipe, which is a socket type concrete pipe, as shown in fig. 4, the joint of the manhole inclined socket 11 and the pipe spigot end 21 is sealed by a rubber gasket 3, so as to further improve the anti-leakage performance.

In an embodiment, the rubber pad 3 is sleeved on the pipeline 2, after the pipeline socket end 21 is inserted into the inclined socket 11 of the inspection well, the rubber pad 3 is fixed on the inspection well body 1 through screws and tightly abuts against the inclined socket 11 of the inspection well, so that leakage is effectively prevented, and meanwhile, the connection mode is convenient for construction.

In one embodiment, the outer wall of the pipe socket end 21 is sleeved with a rubber ring 211, and the rubber ring 211 can make the connection between the pipe socket end 21 and the inclined socket 11 of the inspection well tighter. As shown in fig. 4, two rings of rubber rings 211 may be provided at intervals, and the rubber rings 211 and the rubber pad 3 may be made of common suitable materials such as rubber.

In one embodiment, threaded holes are formed around the horizontal socket 12 of the manhole, and a gasket is added to connect with the flange to form a short joint to be inserted into the female end 22 of the pipeline. Through flange joint mode, also further promote firm and leakproofness.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
