Stone-board road manhole cover with air bags and application method thereof

Abstract

The invention provides a stone-board road manhole cover with air bags and an application method thereof. The stone-board road manhole cover comprises a cushion cover plate located above an inspectionwell, wherein an inspection well inner cover is fixed in the cushion cover plate, a plurality of cushion blocks are fixed to the top of the cushion cover plate, gaps are reserved between adjacent cushion blocks, stone-board cover plates are paved on the upper parts of the cushion blocks, gaps are reserved among the stone-board cover plates, rubber air bags are arranged in the gaps of the cushion blocks in the middle of the cushion cover plate, air guide tubes communicating in the rubber air bags are arranged on the rubber air bags, and the air guide tubes stretch from the gaps and the upper ends of the air guide tubes are provided with inflation ports. By lifting one side of a stone-board away from a pavement by way of inflating the rubber air bags, it is convenient and rapid and hard to hurt hands. A design of the inflation ports can keep integrity of the stone-board pavement so as to achieve an attractive effect. By arranging the cushion blocks flexibly, the stone-board road manholecover can be suitable for stone-board pavements of different specifications and is compatible, simple in structure, convenient to mount, convenient to mount and construct on site and low in cost.

Description

technical field [0001] The invention relates to a flagstone road inspection well cover with an air bag and a using method thereof. Background technique [0002] The inspection well is set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, and street lamp lines, and is convenient for installation. It is generally installed at the intersection of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. Inspection manhole covers are an important part of municipal engineering. They need to be strong, wear-resistant, durable, and beautiful, and they can be easily opened and closed by inspectors. [0003] At present, the commonly used inspection manhole cover with a square frame is better for use on concrete roads, but if it is used on a stone pavement w...

Problems solved by technology

[0004] The present invention improves the above problems, that is, the technical problem to be solved by the present invention is that it is difficult for existing inspection well inspectors to open the well cover, and it is necessary to use a special crowbar to lift the well cover and open it, which may not only wear the slate On the surface, even during the lifting process, due to the sliding of the crowbar, the stone slab will slip and pinch, and the hands and feet will be injured, which has certain potential safety hazards.
