Steel skeleton reinforced polymer composite material inspection manhole cover and anti-falling device

Abstract

The invention provides a steel skeleton reinforced polymer composite material inspection manhole cover and an anti-falling device. The steel skeleton reinforced polymer composite material inspection manhole cover comprises a manhole cover body (1), the anti-falling device (2) and a monitoring device (3). The inspection manhole cover with the double layer safety protection capable of preventing reverse opening, an anti-falling hanging device, the intelligent positioning and the properties of crushing resistance, corrosion resistance, shock absorption and noise reduction is prepared by using theorganic material and the inorganic material as the raw material and conducting ''hypernormal die pressing'' on a steel skeleton of a ''strong truss''.

Description

technical field [0001] The invention belongs to the technical field of road safety equipment, and in particular relates to a steel framework reinforced polymer composite inspection well cover and a fall prevention device. Background technique [0002] Manhole covers are commonly used devices in municipal engineering facilities. They are mostly installed at the interface between drainage pipes, maintenance channels, urban comprehensive pipe galleries, water supply, electricity, communication, etc. To ensure the safety of life and property. However, in recent years, manhole covers have often been lost, crushed, or washed away by the water, causing passers-by to accidentally fall into the drainage pipes and other accidents. The manhole covers installed on the dredging wells installed on the sidewalks of municipal roads are generally made of cast iron, reinforced concrete structures, and composite materials. Due to the heavy reinforced concrete structures, difficulty in opening...

Problems solved by technology

However, the anti-fall net is easy to shake and unstable, and the falling person is likely to sprain the ankle. At the same time, the anti-fall net is prone to aging after a long time, and the support strength decreases. It may not be effective when a person falls.

The double-layer manhole cover often requires a well seat with a special structure, and the cost is relatively high. There are often certain requirements for the well body installation part of the manhole cover used, and it is not suitable for the installation of the old well body.
