Problems solved by technology

[0003] The purpose of the present invention is to provide a composite manhole cover with double sealing strips and drainage parts, which is used to solve the problem of long-term immersion corrosion of the sealing strips by sewage, and micro-leakage of the sealing strips caused by opening wear. To achieve the above-mentioned purpose, the present invention The method adopts a plurality of inclined drainage parts on the circumference of the well base to effectively solve the long-term immersion and corrosion of the sealing belt by sewage and prevent micro-leakage; for the situation of long-term opening of the sealing belt caused by wear and micro-leakage, the present invention is used on the well base Set an annular groove to settle and store micro-leakage sewage, and add another sealing belt, that is, double seal, to prevent sediment and debris from entering the inside of the shaft and keep the inside clean and tidy

Abstract

The invention discloses a composite well lid with double sealing belts and drainage portions. The composite well lid comprises a well seat and a well lid body located on the upper portion of the well seat. The well seat comprises an outer wall, an inner wall and a groove between the outer wall and the inner wall. The top of the outer wall is fixedly connected with the top of the first side wall of the groove through a first connecting plate. The top of the inner wall is fixedly connected with the top of the second side wall of the groove through a second connecting plate. The drainage portions evenly distributed are arranged at the upper end of the first connecting plate. The first sealing belt is arranged on the outer ring face of the well lid body in a surrounding manner, and the second sealing belt is arranged on the bottom face of the well lid body. The composite well lid has the beneficial effects of being reasonable in structural design, convenient to use and wide in application range.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to a composite manhole cover with double sealing strips and drainage parts. Background technique [0002] With the continuous development of the economy, manhole covers are used more and more as coverings for entering the entrances and exits of underground municipal facilities. In the prior art, the seal between the well cover and the well seat generally adopts a single sealing tape sealing method, and the frequent opening of the well cover will cause the sealing tape to wear, cause water leakage, and cause damage to the facilities under the well cover; and the construction and installation of the well cover and well seat After completion, the well base and the ground are at the same level. When there is water on the ground, it will cause water accumulation in the gap between the well cover and the well base. If long-term water accumulation occurs in the gap between the...
