Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and specifically relates to a trough-and-weir combined intercepting well suitable for rainwater and sewage diversion. Background Art

[0002] Under overflow conditions on rainy days, the weir-type intercepting well is generally affected by the height of the weir, which causes water to accumulate in the upstream combined pipe. However, in trough-type intercepting wells, since the trough depth is greater than the designed diameter of the intercepting pipe, when overflowing on rainy days, the water flow in the intercepting pipe becomes a pressure flow condition, and the actual interception volume on rainy days may be greater than the designed interception volume. The premise for the implementation of trough-type intercepting wells in engineering is that the bottom elevation of the intercepting pipe must be lower than the current bottom elevation of the actual combined pipe. The selection of trough-type intercepting wells is subject to many constraints in actual engineering design. Therefore, we propose a trough-weir combined intercepting well suitable for rainwater and sewage diversion. Utility Model Content

[0003] The purpose of the utility model is to provide a trough-and-weir combined intercepting well suitable for rainwater and sewage diversion, so as to solve the problems raised in the above-mentioned background technology.

[0010] Compared with the existing technology, the beneficial effects of the present invention are: the existing interception well is improved, and the characteristics of the weir-type interception well and the trough-type interception well are combined. The improved interception well can adapt to the changes in water volume in different seasons. In the dry season, sewage flows into the original sewage pipe, and in the rainy season, a large amount of sewage can be intercepted in time to avoid impact on rainwater pipes or canals, and avoid causing excessive pressure on the original sewage pipe. The improved interception well can be easily constructed and renovated, especially in the renovation construction of the combined pipe, the interception and drainage tasks can be completed quickly, and the construction efficiency is improved.

[0015] 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.

[0016] See also Figure 1-3 The utility model provides a trough-and-weir combined intercepting well suitable for separating rainwater and sewage, comprising a water reservoir 1, a intercepting plate 2 fixedly connected to the center of the inner wall of the water reservoir 1, a water inlet pipe 4 provided on the side wall of the water reservoir 1, a drainage pipe 5 provided on the other side of the water reservoir 1 away from the water inlet pipe 4, a groove provided on the bottom of the water reservoir 1 on the side of the drainage pipe 5, and sewage pipes 6 symmetrically provided at the groove of the water reservoir 1.

[0017] Combining the characteristics of the weir-type intercepting well and the trough-type intercepting well, in the dry season, sewage flows into the reservoir 1 through the sewage drainage pipe 5. When a certain flow rate is accumulated, the sewage bypasses the interception of the intercepting plate 2 and flows into the groove at the bottom of the reservoir 1 and is discharged through the sewage pipe 6. When the water volume increases in the rainy season, the flow of the reservoir 1 is too much, and the intercepting plate 2 cannot intercept it. The water flow will come into contact with the drainage pipe 5 and be discharged together with the sewage pipe 6 through the drainage pipe 5. The flow is discharged into the rainwater pipe or canal, which can solve the problem of the combined sewer pipe being too large. In the dry season, since there is only sewage in the pipe, the intercepting plate 2 can intercept the sewage and flow it into the sewage pipe 6. In the rainy season, part of the rainwater and sewage will be intercepted and flow into the sewage pipe. The remaining rainwater that exceeds the interception multiple will overflow, and part of it will be discharged into the downstream river through the drainage pipe 5.

[0018] It also includes a baffle structure 3 , which is fixedly assembled on the upper side of the inner wall of the water reservoir 1 , and the lower end of the baffle structure 3 is inserted into the intercepting plate 2 .

[0019] The baffle structure 3 includes a support plate 31, the side wall of the support plate 31 is fixedly connected to the upper inner side of the water reservoir 1, the upper surface of the support plate 31 is fixedly connected to a hydraulic cylinder 32, the other end of the hydraulic cylinder 32 is fixedly connected to a top plate 33, the lower surface of the top plate 33 is fixedly connected to a support rod 34, the side wall of the support rod 34 is matched with the inner cavity gap of the support plate 31, the other end of the support rod 34 is fixedly connected to a baffle 35, the outer wall of the baffle 35 is matched with the inner cavity gap of the intercepting plate 2, through the use of the baffle structure 3, the water flow can be controlled according to different seasons, the support rod 34 and the top plate 33 are controlled by the hydraulic cylinder 32 to rise and fall, the baffle 35 will slide in the inner cavity of the intercepting plate 3, control the interception effect in the water reservoir 1, and achieve more precise interception in different seasons.

[0020] The outer wall of the water inlet pipe 4 is sleeved with a collar 7, and the side wall of the collar 7 is symmetrically fixedly connected with a support block 8. The other end of the support block 8 is fixedly connected to the inner wall of the water reservoir 1. By using the collar 7, a limit is added to the end of the water inlet pipe 4 to prevent the water inlet pipe 4 from shaking when the water flow is large, and to avoid the connection between the water inlet pipe 4 and the water reservoir 1 from loosening for a long time.

[0021] There are two hydraulic cylinders 32 , which are arranged in a transversely symmetrical manner.

[0022] There are two support rods 34 , which are arranged vertically symmetrically.
