Bevel guiding-groove honeycomb-hole manhole cover

Abstract

The invention provides a bevel guiding-groove honeycomb-hole manhole cover, belongs to the technical field of underground pipe network facilities for urban construction, and mainly solves the following problems caused by defects in the structural design of a conventional manhole cover: 1, during the heavy rain or the rapid rain, the drainage capacity of the conventional manhole cover is poor, water gathers and floods the road surface, and the traffic paralysis occurs; and 2, noise is generated when the conventional manhole cover is lost, shifted, turned over and impacted, the vibration structure is fatigued, and the conventional manhole cover is difficult to open. According to the bevel guiding-groove honeycomb-hole manhole cover provided by the invention, the matching mode between a manhole cover body and a manhole is designed as the bevel matching mode, thereby eliminating the clearance and the displacement between the manhole cover body and the manhole; besides, a forked lock being integrated with the manhole cover body is added, thereby thoroughly solving the problems that noise is generated when the conventional manhole cover is lost, shifted, turned over and impacted, the vibration structure is fatigued, and the conventional manhole cover is difficult to open; and meanwhile, flow guiding grooves are designed on the inner side of the bevel manhole, and honeycomb through holes are designed on the obverse side of the manhole cover body, thereby greatly alleviating or thoroughly solving the problem that water gathers and floods the road surface. The bevel guiding-groove honeycomb-hole manhole cover is mainly applied to rain collecting manholes and drainage manholes in all national cities, especially the southern cities with lots of rain.

Description

Technical field: [0001] The invention belongs to the urban construction underground pipe network facility technology. Background technique: [0002] Inspection manhole covers across the country are designed and manufactured according to the relevant standards and diagrams of CJ / T3012-93 and GB / T23858-2009, so their structures are similar, that is, the existing manhole covers are all with large wellheads and small manhole covers, and the manhole covers are deeply embedded in the In the wellhead, the bottom ring of the manhole cover rests on the supporting ring in the middle of the wellhead. In order to facilitate the opening and exit of the manhole cover, there is a wide enough gap between the wellhead and the manhole cover. Many small holes for water to flow in. Invention content: [0003] The disadvantages and deficiencies of existing well covers: 1. Although the gap between the well cover and the wellhead is large, it is filled with silt and garbage, which not only cann...

Problems solved by technology

[0003] The disadvantages and deficiencies of existing well covers: 1. Although the gap between the well cover and the wellhead is large, it is filled with silt and garbage, which not only cannot drain into the well but makes it very difficult to open the well cover, and the well cover is under pressure. It is difficult to pass through the tight fit
