Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0025] Such as Figure 1-Figure 4 As shown, the present embodiment provides an anti-scouring device for a manhole cover of a rainwater inspection well. The anti-scouring device is suitable for a cover-type rainwater inspection well. The top cover is provided with a well cover 6, and the anti-shock device includes a bolt 3 and a cross bar 4, the bolt 3 is parallel to the central axis of the shaft 1, the head end of the bolt 3 is connected with the well cover 6, and the other end is vertically connected with the end of the cross bar 4, The upper surface of the cross bar 4 abuts against...

Abstract

The invention relates to a device for preventing a well lid of a rainwater inspection well from being washed away. The device is suitable for the cover plate type rainwater inspection well which comprises a shaft and a well chamber. The shaft and the well chamber are communicated with each other. The well lid is arranged on the top of the shaft in a covering mode. The device comprises a bolt and a transverse rod. The bolt is parallel to the central axis of the shaft. The head end of the bolt is connected with the well lid, and the other end of the bolt is perpendicularly connected with the end of the transverse rod. The upper surface of the transverse rod abuts against the top of the well chamber. When water in a sewer surges to the well lid, the transverse rod is limited by the top of the well chamber so that the well lid connected with the bolt can not be ejected. Compared with the prior art, the device has the advantages of being convenient to install and detach, simple in structure, and the like.

Description

technical field [0001] The invention relates to a rainwater inspection well cover, in particular to an anti-scouring device for a rainwater inspection well cover. Background technique [0002] The rainwater inspection well cover is the closure on the top of the entrance to the underground rainwater drainage facility. The manhole cover is the main supporting product of the inspection well. Its functions are load-bearing, sealing, and opening of the inspection well. It can not only withstand the high-speed driving of traffic vehicles, but also prevent the entry of vehicles, pedestrians and foreign objects, and ensure the normal use of underground pipelines. [0003] Manhole covers for inspection wells are divided by material, mainly divided into metal manhole covers (cast iron, ductile iron, bronze manhole covers, etc.), high-strength steel fiber cement concrete manhole covers (cement-based composite materials), recycled resin manhole covers (regenerated resin-based composite ...
