Height-adjustable well lid and adjusting method thereof

Abstract

The invention discloses a height-adjustable well lid and an adjusting method thereof, and relates to the technical field of urban public facilities. The height-adjustable well lid comprises a well lidbody, a supporting base and a fixing base, wherein the fixing base is fixedly installed on the side wall of a sewer wellhead, the supporting base is fixedly installed on the top face of the fixing base through supporting bolts, the well lid body is fixedly installed in an installing groove in the side wall of the supporting base through an installing block, the installing block is fixedly installed on the bottom face of the installing groove through installing bolts, and therefore the well lid body is fixedly installed on the top of the supporting base, and installation of the well lid body is completed; meanwhile, a lifting mechanism and a supporting mechanism are arranged in the fixing base, the lifting mechanism is driven by an adjusting box to work, and the lifting operation of the supporting base is completed; and different from a traditional mode that single height adjustment is carried out through adjusting bolts, leveling is more convenient; meanwhile, the supporting base is supported by the supporting mechanism, that the supporting base shakes after rising is avoided, and the stability of the well lid is guaranteed.

Description

technical field [0001] The invention relates to the technical field of urban public facilities, in particular to a height-adjustable manhole cover and an adjustment method thereof. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. According to the material, it can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Usually round. It can be used for green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. [0003] During the construction of asphalt road, at least 4 layers are required, namely backfill soil compaction, roadbed compaction, concrete bottom layer, and asphalt pavement layer. Usually, manhole covers should be pre-placed before laying backfill soil compaction, roadbed compaction and concrete bottom layer. , During the laying process, the manhole cover is positioned and fixed, and the height of the tradition...

AI Technical Summary

Problems solved by technology

[0003] During the construction of asphalt road, at least 4 layers should be laid, which are backfill compaction, roadbed compaction, concrete bottom layer, and asphalt pavement layer. Usually, the manhole cover should be placed in advance before laying backfill compaction, roadbed compaction and concrete bottom layer During the laying process, the manhole cover is positioned and fixed, and the height of the traditional manhole cover is fixed. However, when laying the road surface, the height of the laying layer often has a large error. Either the manhole cover is higher than the road surface, or the manhole cover is lower than the road surface. The road surface is even, and there is a height difference between the road surface and the manhole cover. Vehicles pass by on the road all the year round. On the one hand, it will cause damage to the vehicle, and on the other hand, it will affect the life of the manhole cover. At the same time, it is easy to generate noise due to bumps
