Description

Technical Field

[0001] The utility model relates to the technical field of interception wells, in particular to a channel interception device with a mud settling function. Background Art

[0002] The interception-type combined sewer system is suitable for areas where the existing drainage facilities are intact and the construction of new pipelines is difficult. An interception well is set at the sewage outlet of the existing combined sewer system, and a new interception main pipe is built. On sunny days and when it rains, sewage and initial rainwater are intercepted and sent to the sewage treatment plant for discharge after treatment. When the rainfall increases and the flow of mixed sewage exceeds the interception capacity of the interception main pipe, part of the mixed sewage will overflow through the overflow well and be directly discharged into the original channel receiving water body.

[0003] At present, although the commonly used intercepting wells are equipped with grilles, a large amount of mud and sand will still flow into the intercepting wells during rainfall, and a large amount of manpower and material resources are required to regularly go down the well to clean out the mud and sand, which is very inconvenient for operation. In addition, going down the well to clean out the mud and sand is a confined space operation, which poses a great safety hazard. The present application provides a liftable mud bucket in the intercepting device, and the mud bucket is lifted to the outside of the well for cleaning through a transmission device, which greatly reduces the manpower and material resource consumption of going down the well to clean out the mud and avoids the occurrence of safety accidents in confined space operations underground. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a channel intercepting device with a silt settling function, which has the advantage of being easy to clean the silt in the intercepting well, and solves the problem that a large amount of silt will flow into the intercepting well in the prior art, and a large amount of manpower and material resources are required to regularly go down the well to clean out the silt, which is very inconvenient to operate, and the cleaning down the well is a confined space operation, which poses a great safety hazard.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a channel interception device with a sedimentation function, comprising a concrete cover plate, an interception well and a sedimentation bucket, wherein a sediment deposition and cleaning mechanism is provided between the interception well and the sedimentation bucket;

[0006] The sediment deposition cleaning mechanism comprises an inlet channel and an outlet channel fixedly mounted on the outer surface of the intercepting well, an intercepting main pipe and an expansion hook are fixedly mounted on the inner surface of the intercepting well, lifting ears are welded at the four corners of the top of the sediment hopper, a steel wire rope is fixedly mounted on the lifting ears, and a lifting ring is fixedly mounted on the steel wire rope.

[0007] Furthermore, a grille is provided at the connection between the water inlet channel and the interception well.

[0008] Furthermore, the water inlet channel and the water outlet channel are vertically arranged on the surface of the interception well, the water inlet channel and the water outlet channel are both connected to the interception well, and the height of the interception main pipe is lower than the height of the water inlet channel and the water outlet channel.

[0009] Furthermore, the steel wire rope is arranged between two lifting ears, both ends of the steel wire rope are fixedly connected to the lifting ears, and the lifting ring is located in the middle of the steel wire rope.

[0010] Furthermore, a support seat is fixedly installed at the bottom of the intercepting well, and the internal shape and size of the support seat are matched with the external shape and size of the sludge bucket.

[0011] Furthermore, the concrete cover plate is matched with the wellhead of the intercepting well, and the concrete cover plate is arranged at the top of the wellhead of the intercepting well.

[0012] Furthermore, a ladder is fixedly installed on the inner surface of the interception well, and the ladder corresponds to the interception main pipe.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The channel intercepting device with a sedimentation function is provided with a sedimentation bucket which can be lifted to the outside of the intercepting well at the bottom of the intercepting well, so as to collect sediment washed into the intercepting well from the water inlet channel due to rain. The sedimentation bucket can be lifted to the outside of the intercepting well by a transmission lifting device to clean the sediment in the bucket, thereby avoiding manual cleaning in the well, achieving efficient cleaning of the sediment, and avoiding the occurrence of safety accidents in the confined space operation underground. The grid can be provided to prevent large floating objects and particulate matter from entering the intercepting main pipe, thereby avoiding the blockage of the downstream sewage pipe due to the floating objects. The problem of a large amount of sediment pouring into the intercepting well in the prior art is solved, and a large amount of manpower and material resources are required to regularly clean the sediment in the well, which is very inconvenient to operate, and the well cleaning belongs to the confined space operation, which has a great safety hazard.

The concrete cover plate 11 is adapted to the wellhead of the interception well 1. The concrete cover plate 11 is arranged at the top of the wellhead of the interception well 1 to facilitate closing the wellhead of the interception well 1. A silt deposition and cleaning mechanism is arranged between the interception well 1 and the silt settling bucket 5. The silt deposition and cleaning mechanism includes an inlet channel 2 and an outlet channel 9 fixedly installed on the outer surface of the interception well 1. An interception main pipe 4 and an expansion hook are fixedly installed on the inner surface of the interception well 1. 7.

The water inlet channel 2 and the water outlet channel 9 are vertically arranged on the surface of the interception well 1. The water inlet channel 2 and the water outlet channel 9 are both connected to the interception well 1. The height of the interception main pipe 4 is lower than that of the water inlet channel 2 and the water outlet channel 9, which is beneficial to ensure that the incoming water can intercept sewage to the maximum extent after entering the interception well 1. A ladder 10 is fixedly installed on the inner surface of the interception well 1, and the ladder 10 corresponds to the interception main pipe 4, which is convenient for the staff to enter the interior of the interception well 1.
