Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage pipes, in particular to a municipal drainage pipe structure. Background Art

[0002] The drainage system is an important part of municipal construction. A good drainage system can ensure the convenience of residents' lives and smooth traffic. The quality of the drainage system depends on the joint action of the sewer, drainage pipes, and sewers. Since the drainage pipes occupy a large area and are long in the drainage system, the drainage performance of the drainage pipes has a vital impact on the quality of the drainage system.

[0003] When the drain pipe is blocked, a high-pressure water truck is needed to insert a high-pressure water pipe into the drain pipe for cleaning. However, the outlet of the drain pipe is located at the bottom of the inspection well. When the drain pipe is blocked by too much silt, the inspection well also buries the outlet of the drain pipe. It is difficult to find the outlet of the drain pipe and insert the high-pressure water pipe. In addition, when the drain pipe mouth is blocked, the blockage at the pipe mouth must be manually cleaned before the high-pressure water pipe can be placed in the drain pipe. It is very inconvenient to clean impurities at the pipe mouth. Utility Model Content

[0019] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0020] The municipal drainage pipe structure is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-3 As shown, the utility model provides a municipal drainage pipe structure, including a drainage main pipe 1 and an auxiliary side pipe 2, a connector 3 is sleeved on one end of the drainage main pipe 1 close to the inspection well, and the connector 3 is used to connect the auxiliary side pipe 2 to the side wall of the drainage main pipe 1; a blocking piece 34 is arranged between the end of the auxiliary side pipe 2 and the drainage main pipe 1, and a flexible connecting part 341 is arranged on the side of the blocking piece 34 away from the water outlet of the drainage main pipe 1, and easy-to-break connecting parts 342 are arranged around the blocking piece 34. When high-pressure water is injected into the auxiliary side pipe 2, the easy-to-break connecting part 342 is disconnected, so that the drainage main pipe 1 and the auxiliary side pipe 2 are internally connected. When the inspection well and the drainage pipe 1 are both blocked by silt and debris, high-pressure water is injected from the auxiliary side pipe 2, and the easily breakable connection part 342 of the blocking piece 34 is broken under the action of the high-pressure water, so that the blocking piece 34 is connected only by the flexible connection part 341. Since the flexible connection part 341 is located on the side away from the water outlet of the drainage pipe 1, the blocking piece 34 at this time guides the water flow in the direction of the water outlet of the drainage pipe 1, and removes the impurities at the end of the drainage pipe 1, so that the high-pressure water pipe can be easily inserted into the drainage pipe 1. The easily breakable connection part 342 of the blocking piece 34 prevents the auxiliary side pipe 2 from being blocked by impurities in the initial state.

[0022] The specific structure of the connector 3 is that the connector 3 includes an upper connection part 31 and a lower connection part 32, and the upper connection part 31 and the lower connection part 32 are respectively sleeved on the upper and lower sides of the drainage main pipe 1, and both sides of the upper connection part 31 and the lower connection part 32 are provided with connection ears, and the connection ears are locked by screws. The connector 3 is fixed to the drainage main pipe 1 in the form of a clamp, so that it is convenient and quick to connect.

[0023] Furthermore, a connecting sleeve 33 is provided at the top of the connecting upper part 31, the auxiliary side pipe 2 is threadedly connected to the connecting sleeve 33, the blocking sheet 34 is located in the connecting sleeve 33, and the drainage main pipe 1 is provided with a connecting through hole 11 below the connecting sleeve 33. Before installation, a hole is firstly punched on the drainage main pipe 1, and then the installation position of the connector 3 is adjusted so that the connecting through hole 11 is located below the connecting sleeve 33.

[0024] Regarding the position setting of the auxiliary side pipe 2, the other end of the auxiliary side pipe 2 extends to above the outlet of the drainage main pipe 1 and is located at the top of the inspection well. Regarding the connection relationship of the blocking sheet 34, a gap is set between the blocking sheet 34 and the inner wall of the connecting sleeve 33, and the breakable connection part 342 is set at intervals. The gap allows gas communication between the drainage main pipe 1 and the auxiliary side pipe 2. Under normal conditions, the auxiliary side pipe 2 can play the role of aeration, reduce the content of flammable gas in the pipeline, and avoid the risk of explosion in the inspection well.
