Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and particularly relates to an inspection well for municipal rain and sewage pipelines. Background Technique

[0002] Municipal refers to the various administrative management works of a city, and also refers to market trade affairs. Urban management work includes industry and commerce, transportation, public security, culture and education, environment, sanitation, capital construction, etc. An inspection well is used in a building community where the outer diameter of the buried plastic drainage pipeline does not exceed 800 mm and the burial depth does not exceed 6 m. It is generally set at the intersection of drainage pipelines, turning points, pipe diameter or slope change points, drop water points, etc. It is a well-shaped structure made of plastic injection molding or brickwork for facilitating regular inspection, cleaning, dredging or down-well operation inspection.

[0003] In an inspection well for municipal rain and sewage pipelines disclosed in the patent with the publication number CN215253318U, although, through the grooving, return spring, connecting seat and warning rod, when the rainfall is large, the manhole cover needs to be opened, and the return spring drives the warning rod to rotate to ensure that the warning rod is in a vertical state and can be exposed on the ground, which can warn pedestrians and vehicles and ensure the safety of pedestrians and vehicles.

[0004] However, this inspection well for municipal rain and sewage pipelines has the following disadvantages:

[0005] (1) This inspection well for municipal rain and sewage pipelines has a weak function of supporting the manhole cover. When in use, after the manhole cover is opened, the staff needs to place it aside, and the back-and-forth handling will consume too much physical strength, which is not conducive to the work development.

[0006] (2) This inspection well for municipal rain and sewage pipelines has a weak function of fixing the pipeline. When in use, since the sewage pipeline needs to discharge sewage and rainwater, after the sewage and rainwater are pumped and discharged outward, due to the excessive impact force over a long time, the pipeline displacement will occur. Content of the Utility Model

[0007] The purpose of the utility model is to provide an inspection well for municipal rain and sewage pipelines to solve the problems raised in the above background technique.

[0008] To achieve the above purpose, the utility model provides the following technical solution: An inspection well for municipal rain and sewage pipelines, including a well body, a clamping groove is opened at the top end of the well body, a manhole cover is rotatably connected to the inner wall of the clamping groove, a fixing rod is arranged at the bottom end of the manhole cover, a slot is opened at the inner bottom wall of the clamping groove, a pipeline is arranged at the bottom end of the well body, a fixing block is fixedly connected to the surface of the pipeline, a cone is fixedly connected to one side of the fixing block, and a bolt is threadedly connected to one side close to the cone.

[0009] Optionally, a placement groove is provided on the inner wall of the well body, and an anti-slip pad is fixedly connected to the inner bottom wall of the placement groove. When it is necessary to collect and detect the drained water body, it is necessary for the staff to enter the well body. They can step on the placement groove, and the anti-slip pad is used for anti-slip to stabilize the staff's body.

[0010] Optionally, a clamping groove is provided on one side of the inner wall of the well body close to the placement groove, and an emergency lamp is fixedly connected to the inner wall of the clamping groove. The emergency lamp is externally powered to illuminate the inside of the well body.

[0011] Optionally, a fixing groove is provided at the top of the manhole cover, and a reflective sticker is fixedly connected to the inner wall of the fixing groove. The reflective sticker can reflect light at night when the light conditions are poor to warn the road on one side.

[0012] Optionally, an inner handle is provided on one side of the manhole cover surface close to the reflective sticker. The installation of the inner handle facilitates the staff to manually lift the manhole cover.

[0013] Optionally, a drainage hole is provided on one side of the manhole cover surface close to the inner handle. The drainage hole can overflow outward when there is a large amount of wastewater in the pipeline to avoid excessive internal pressure.

[0014] Compared with this device, the beneficial effects of the present utility model are:

[0015] 1. For this inspection well for municipal rain and sewage pipelines, through the settings of the manhole cover, fixed rod and slot, during use, the manhole cover is connected to the fixed rod. After the manhole cover is manually lifted, the fixed rod is extended and inserted into the slot to fix the manhole cover upright, eliminating the need to place it aside and occupy space, and also avoiding the inconvenience caused by the staff's handling. Thus, the effect of being able to fix the manhole cover without handling it for easy inspection work is achieved.

[0016] 2. For this inspection well for municipal rain and sewage pipelines, through the settings of the pipeline, fixed block, cone and bolt, during use, the fixed block is fixed by the pipeline. The cone can be inserted into the well body and then fixed by pouring concrete. The cone is in an inverted cone shape to firmly fix the pipeline, and then by rotating the bolt, the fixation can be strengthened, making the pipeline more stable when impacted and not shifting. Thus, the effect of strengthening and fixing the pipeline is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
