Description

Technical Field

[0001] The utility model relates to the technical field of flood control belts, in particular to an emergency flood control belt for a road manhole cover. Background Art

[0002] Pavement manhole covers, also known as road manhole covers, are a type of covering installed in urban roads, squares, parking lots and other places to close the entrances and exits of underground pipes, ditches, equipment and other passages.

[0003] The main function of manhole covers is to protect the safety of underground facilities and prevent pedestrians, vehicles, etc. from accidentally falling in, while also making it convenient for relevant staff to carry out maintenance and inspection work.

[0004] A flood belt is a temporary waterproof barrier used to prevent flood backflow. It is usually made of plastic, rubber and other materials and can be quickly installed in areas that need flood protection, such as around manhole covers, doors, windows, etc. In emergency situations such as heavy rain and floods, flood belts can effectively prevent floods from entering buildings or streets, reducing the degree of urban waterlogging.

[0005] The manhole cover emergency flood protection strip is a temporary flood prevention measure, mainly used to prevent rainwater, sewage, etc. from flowing back into the streets from the sewer manhole cover in emergency situations such as heavy rain and floods. This flood protection strip is usually made of plastic, rubber and other materials and can be quickly installed around the sewer manhole cover to form a sealed waterproof barrier.

[0006] At present, in order to prevent floods from pouring into the city through the manhole covers when floods occur, it is necessary to divert the floods when floods occur in the periphery, avoiding the manhole covers as much as possible to reduce urban waterlogging. At the same time, floods can easily wash away the manhole covers when they pass through them. If pedestrians accidentally pass by the manhole covers, they can easily fall into the well and cause life-threatening danger.

[0007] Therefore, it is necessary to design a flood protection belt structure on the manhole cover. In addition, in order to avoid the low waterproof height of the conventional flood protection belt, further improvements are needed to add a water retaining structure on the basis of the flood protection belt to increase the flood protection height. Utility Model Content

[0011] In detail, the number of the bases is at least six, and they are evenly and equidistantly distributed.

[0012] In detail, the strap is made of canvas material, and the surface is coated with polyvinyl chloride.

[0013] In detail, the flood control belt is composed of a wear-resistant layer, a leak-proof layer and a filling layer in sequence, the inside of the wear-resistant layer is wrapped with the leak-proof layer, and the filling layer is filled inside the leak-proof layer.

[0014] In detail, the wear-resistant layer is made of polypropylene resin by drawing.

[0016] In detail, the filling layer is made of fine sand material.

[0017] The design scheme proposed by the utility model has the following beneficial effects during application:

[0018] 1. The flood control belt structure is arranged in a ring shape, which can be placed around the manhole cover to form a ring-shaped enclosure, so that when the flood passes, it can avoid the manhole cover as much as possible. Adding a casing structure to the flood control belt can further increase the height of the flood control. When the flood depth is large, it can also prevent the flood from passing through the manhole cover.

[0019] 2. The casing structure is placed on the flood control belt through the base, and through multi-point setting, combined with the binding of the straps and the base, the casing can be stably erected on the flood control belt. The fine sand filled in the flood control belt can ensure the weight stability of the entire bottom, thereby ensuring the compressive stability of the casing during flood control.
