An adjustable manhole cover structure for municipal construction

Abstract

The invention relates to an adjustable well lid structure for municipal administration construction, and belongs to the technical field of municipal administration construction equipment. A lid base is included. The upper surface of the lid base is provided with a groove. A through hole is formed in the middle of the groove and internally provided with a fixing barrel. The side face of the fixingbarrel is fixedly connected with the inner wall of the groove through a plurality of fixing plates. The adjacent fixing plates divide the lid base into a plurality of sector sections. Cover plates matched with the sector sections are arranged in the sector sections and provided with a plurality of water guiding holes. The cover plates are arranged in the groove and are in sliding connection with the groove. A sliding mechanism for controlling sliding of the cover plates is arranged in the fixing barrel. Through cooperation of the fixing plates and the fixing barrel, the well lid is equally divided into the multiple sector sections, the water discharging area is increased when the cover plates in the sector sections outwards slide, adjustment can be conducted according to different weatherconditions, controllability of the water discharging efficiency is greatly improved, the situation that accumulated water is hard to discharge or people and objects are sucked is avoided, and usage ismore convenient and safer.

Description

technical field [0001] The invention relates to the technical field of municipal construction equipment, in particular to an adjustable manhole cover structure for municipal construction. Background technique [0002] In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, etc. During road construction, sewers and appropriate manhole covers are usually installed to avoid road accumulation. [0003] The structure of the existing manhole cover is fixed, resulting in a certain amount of drainage. In order to prevent debris from entering and blocking or affecting ...

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing manhole cover is fixed, resulting in a certain amount of drainage. In order to prevent debris from entering and blocking or affecting the safety of pedestrians and animals due to the large drainage holes, the design of the drainage holes is relatively small, and the drainage is relatively small in special weather such as heavy rain. Wells are prone to stagnant water leading to traffic paralysis, and when the manhole cover is completely opened when the water is stagnant, it is easy to form eddies or traps, affecting traffic safety
