Description

Technical Field

[0001] The utility model relates to the technical field of municipal pipelines, in particular to a water-stopping connecting device for a sewage inlet pipeline. Background Art

[0002] Sewage treatment plants are generally located downstream of urban sewage pipe networks. Their inlet pipelines are characterized by large sewage flow, high pipe network water levels, and deep burial depths. Generally speaking, the connection between the inlet pipe of a newly built sewage treatment plant and the existing sewage main pipe requires water outage. Once the terminal pipe network is blocked and the water supply is cut off, it will have a certain impact on both the upstream and downstream of the sewage system, especially the sewage overflow problem, which can easily pollute the water environment. Therefore, how to connect the existing sewage pipes without water outage, reduce the sewage overflow problem during the connection process, and reduce the quality and safety risks during the construction process has always been the focus and difficulty of sewage treatment plant pipeline construction.

[0022] The utility model aims to solve the technical problem in the prior art that the connection between the inlet pipe of a newly built sewage treatment plant and the existing sewage trunk pipe requires water outage, and provides a sewage inlet pipeline non-stop connection device.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 The present invention provides a non-stop water connection device for a sewage inlet pipeline, comprising a connection well 1, a first sewage pipe 3, a connection box culvert 2, and a water-retaining steel plate 5. The connection well 1 is configured as a square, enclosed structure, such as a rectangular connection well 1 employed in this embodiment. The connection well 1 comprises a first well wall, a second end well wall, a third well wall, and a fourth well wall, with the first well wall and the second well wall positioned opposite each other, and the third well wall and the fourth well wall positioned opposite each other. To further prevent water from overflowing from the top of the connection well during the connection process, the connection well 1 can be elevated.

[0025] The first sewage pipe 3 is the original sewage discharge pipe, and the first sewage pipe 3 passes through the first well wall and the second well wall of the connecting well 1. The connecting box culvert 2 is a closed structure, and the connecting box culvert 2 is fixed to the outside of the third well wall of the connecting well 1. The connection between the connecting box culvert 2 and the connecting well 1 is anti-seepage treated. A connecting hole is provided on the connecting box culvert 2, and one end of the newly added second sewage pipe 4 extends to the interior of the connecting box culvert 2 through the connecting hole and is fixedly connected to the connecting box culvert 2. The water-retaining steel plate 5 is fixed to the inner side of the third well wall of the connecting well 1. For example, the water-retaining steel plate 5 can be fixed to the inner side of the third well wall of the connecting well 1 by expansion screws 7, so that the water-retaining steel plate 5 can be removed after the entire connecting work is completed. A water-stop rubber belt is provided between the water-retaining steel plate 5 and the inner side of the third well wall of the connecting well 1 to further increase the anti-seepage ability of the connection between the water-retaining steel plate 5 and the connecting well 1. In order to facilitate the drilling of holes in the third well wall to connect the connecting well 1 and the connecting box culvert 2, the water retaining steel plate 5 can be set as an inverted "U"-shaped steel plate structure, and the opening position is exactly in the middle of the inverted "U"-shaped steel plate structure. Compared with the whole anti-seepage high plate, the inverted "U"-shaped steel plate structure will not block the hole when drilling, which is more conducive to the drilling operation.

[0026] To further improve the reliability of securing the water retaining steel plate 5, a preferred embodiment of the present invention further comprises a cross brace 6; one end of the cross brace 6 is detachably secured to the inner side of the fourth wall of the connecting well 1, and the other end of the cross brace 6 is detachably secured to the water retaining steel plate 5, thereby providing transverse support to the water retaining steel plate 5. The cross brace 6 can be constructed of various components with high structural strength, such as an I-beam structure; the cross brace 6 is provided in at least one group, and when multiple groups are provided, the multiple groups are symmetrically distributed to ensure uniform force on the water retaining steel plate 5.

[0027] See also Figure 1 and Figure 2 The working process of the sewage inlet pipeline non-stop water connection device provided by the embodiment of the utility model is as follows: when it is necessary to connect the newly added second sewage pipe 4, the flow rate of the first sewage pipe 3 is reduced without stopping the water. First, the second sewage pipe 4 is connected to the connection hole on the connection box culvert 2, and the connection is treated with anti-seepage. Then, a hole is drilled at the third well wall to connect the connection well 1 with the connection box culvert 2, so that the newly added second sewage pipe 4 can be connected to the pipeline where the original first sewage pipe 3 is located. Then, the water-retaining steel plate 5 and the cross brace 6 are removed, and the connection well 1 is sealed to restore the normal flow of the second sewage pipe 4.

[0029] The embodiment of the present utility model provides a non-stop water connection device for the sewage inlet pipeline, and the connection well 1 is configured as a square closed structure; the connection well 1 is provided with a first well wall, a second end well wall, a third well wall and a fourth well wall, the first well wall and the second well wall are arranged oppositely, and the third well wall and the fourth well wall are arranged oppositely. The first sewage pipe 3 passes through the first well wall and the second well wall of the connection well 1; the connection box culvert 2 is fixed on the outside of the third well wall of the connection well 1. One end of the second sewage pipe 4 extends to the interior of the connection box culvert 2 and is fixedly connected to the connection box culvert 2. The water-retaining steel plate 5 is fixed on the inner side of the third well wall of the connection well 1; one end of the cross brace 6 is detachably fixed to the inner side of the fourth well wall of the connection well 1, and the other end of the cross brace 6 is detachably fixed to the water-retaining steel plate 5. The sewage inlet pipeline has a non-stop water connection device. Since a water-retaining steel plate 5 is provided on the inner side of the third well wall of the connection well 1, during the process of connecting the third well wall opening with the connection box culvert 2, the water in the connection well 1 is blocked by the water-retaining steel plate 5 and will not overflow, which will not affect the normal operation of the original first sewage pipe 3; after the newly added second sewage pipe 4 is connected to the connection box culvert 2, the water-retaining steel plate 5 is removed to connect the connection well 1 with the connection box culvert 2 to realize the connection of the newly added second sewage pipe 4 to the pipeline where the original first sewage pipe 3 is located; the entire connection work does not require the water supply to the first sewage pipe 3 to be stopped.
