Road well lid

Abstract

A road well lid comprises a surface layer, an inner layer and a steel skeleton force transfer frame. The surface layer of the well lid is a dense nylon alloy layer. The inner layer of the well lid is a nylon alloy and sunflower seed flake-like stone mixing layer. The steel skeleton force transfer frame is arranged in the inner layer. The steel skeleton force transfer frame is in a mesh shape formed by mutually welding a plurality of downward concave V-shaped deformed steel bars, and the two endpoints of each V-shaped deformed steel bar are fixedly connected to the same metal tension ring. According to the road well lid, the surface layer of the well lid is made of nylon alloy, the inner layer of the well lid is made of a mixture of nylon alloy and stone, and enhanced manufacturing is achieved with the addition of the steel skeleton force transfer frame, so that different performance advantages of unlike materials are integrated, the central loading force of the well lid is moved to the edge of the well lid and transferred to the well wall through the steel skeleton force transfer frame, and accordingly the bearing capacity of the well lid is substantially improved. The road well lid has the remarkable advantages of firmness, theft prevention, shock absorption, noise reduction, corrosion resistance, insulation, abrasion resistance, weatherproofness, eternal non-deformation, long-term non-aging, long service life, and the like.

Description

technical field [0001] The invention relates to a road manhole cover, in particular to a road manhole cover without recycling value, which belongs to the road facility manufacturing technology. Background technique [0002] With the continuous increase, expansion and development of urban roads, inspection manhole covers for various underground facilities on the road, such as: tap water manhole covers, sewer manhole covers, power line manhole covers, communication line manhole covers, natural gas pipeline manhole covers, etc. are increasing rapidly. Traditional road manhole covers include: cast iron manhole covers, concrete manhole covers, waste plastic manhole covers, resin composite manhole covers, etc. Among them, cast iron manhole covers are widely used because of their high strength and long life. However, cast iron manhole covers are easy to be stolen. According to incomplete statistics: more than 2,000 road manhole covers of various types are stolen in a medium-sized c...

AI Technical Summary

Problems solved by technology

Among them, cast iron manhole covers are widely used because of their high strength and long life. However, cast iron manhole covers are easy to be stolen. According to incomplete statistics: more than 2,000 road manhole covers of various types are stolen in a medium-sized city in a year, and the supplementary cost is extremely high. Concrete manhole covers, that is, concrete manhole covers, have a small load capacity and are easy to peel off and break; waste plastic manhole covers are easy to deform and age; resin composite manhole covers are more expensive because of their manufacturing costs, and a large amount of stone powder is usually added to make them brittle and unable to bear.

Regardless of the form of damage to the above-mentioned manhole cover, if it is not replaced and supplemented immediately, the consequences of road obstacles will be extremely serious
