Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage, and specifically relates to a node for connecting a branch line with a large trunk line. Background Art
[0002] Urban development is getting faster and faster. When building roads, many cities hope to avoid damaging the road surface as much as possible. However, it is very difficult to connect the branch line with the main line without damaging the road surface. Although the main line can use non-excavation technology such as shield, the construction method of connecting the branch line with the main line is still grooving construction, which damages the road surface and affects traffic. When the water volume of the main line is large and the water level is high, the existing construction method of connecting the branch line with the main line requires the main line to be blocked first and then water is diverted. While damaging the road surface, ground traffic is also affected, and the construction cost will increase significantly, which is time-consuming, labor-intensive and costly. Therefore, we propose a node for connecting the branch line with a large trunk line. Utility Model Content
[0003] The purpose of the utility model is to provide a node for connecting a branch line with a large trunk line to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a node where a branch line is connected to a large trunk line, comprising an inspection well, a drainage main line pipeline is installed on one side of the inspection well, a drainage branch line pipeline is installed on the other side of the inspection well, and a closed structure is arranged on the side close to the drainage main line pipeline, and the side wall of the closed structure is connected to the inner wall of the inspection well.
[0005] Preferably, the closed structure includes two embedded steel plates, which are symmetrically embedded in the inner wall of the inspection well, and the inner walls of the two embedded steel plates are symmetrically fixedly connected with concave guide rails, and a cast iron plate is inserted between the inner walls of the two concave guide rails, and the corners of the cast iron plate are in contact with the inner wall of the inspection well.
[0006] Preferably, an opening is provided on one side of the top of the inspection well, and the side walls of the opening of the inspection well are symmetrically fixedly connected with internal threaded rods, the outer walls of the two internal threaded rods are sleeved with top covers, the inner cavity of the top covers is sleeved with a clamping block, the lower surface of the clamping block is fixedly connected with a screw rod, the outer wall of the screw rod is threadedly connected to the inner cavity of the internal threaded rod, and the upper surface of the clamping block is fixedly connected with a turning handle.
[0007] Preferably, the upper surface of the cast iron plate is fixedly connected with square hanging rings, and the number of the square hanging rings is three and they are arranged in sequence.
[0008] Preferably, a through hole is provided at the center of the top cover, and the through holes are evenly arranged.
[0009] Compared with the prior art, the beneficial effect of the utility model is that when the main line is built, the connection node between the branch line and the main line has been completed. In the long term, it is only necessary to connect the branch line to the drainage branch pipe in the inspection well. The product can be constructed quickly, and only needs to be constructed at night, and it can be restored to normal the next day. The cast iron plate is removed by lifting equipment and water is immediately passed. The construction of this product is simple and fast, and the later cost is relatively low. The utility model can realize the connection between large trunk lines and drainage branch pipes without damaging the road surface, thereby minimizing the impact on urban traffic, and the connection is stable and the structure is coordinated.
