a road safety well

Abstract

The invention discloses a road safety well. The road safety well comprises a well cover body and a well cover seat which is fixed to the inner upper end of a well mouth; the well cover seat is annular; the distance between the upper end surface of the well cover seat and the top end of the well mouth is equal to the thickness of the well cover body, and a plurality of through holes are uniformly distributed in the well cover seat; installation tables are fixed to the inner wall of the portion, under the through holes, of the well mouth; air cylinders with the openings facing downwards are disposed on the installation tables; ventilation holes used for making the lower portions of the interiors of the air cylinders communicate with the well mouth are formed in the installation tables; and aplurality of air guiding grooves extending from the center of the well cover body to the edge of the well cover body are uniformly formed in the lower end of the well cover body. Usage is convenient,the impact speed and impact force of the well cover body are greatly reduced when an explosion occurs through repeated buffering and energy absorbing, the bouncing height of the well cover body is limited, and too high bouncing is avoided so that pedestrians cannot be affected or injured; automatic and accurate restoration can be achieved after explosion occurs; the well cover body is not prone to being damaged, and the service life of the well cover body is prolonged; and installation and maintenance are convenient.

Description

technical field [0001] The invention relates to the field of municipal facilities, in particular to a road safety well. Background technique [0002] As a public facility, urban roads are becoming more and more important in today's era of continuous improvement of urban taste and creation of civilized cities. The quality of the manhole cover of the safety well directly affects the maintenance cost and driving safety. Manhole covers can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers according to their materials. The manhole cover is the closure on the top of the entrance and exit leading to the underground facilities. It is necessary to install the manhole cover wherever public facilities such as tap water, telecommunications, electricity, gas, heat, fire protection, and sanitation are installed. With the rapid development of my country's economy, my country's infrastructure construction has ushered in a ne...
