Embodiment Construction

[0054] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0055] like Figure 1-8 As shown, a municipal well cover of the present invention includes a circular well base 1 and a circular plate-shaped cover body 3 arranged in the well base 1. The inner wall of the well base 1 is provided with an annular retaining ring 11, and the top surface of the retaining ring 11 is low. It is on the top surface of the well base 1 and is perpendicular to the inner wall of the well base 1. It also includes a number of support columns 12 whose bottom ends are fixed to the top surface of the stop ring 11. The length direction of the support columns 12 is parallel to the axis of the stop ring 11. The top of the support column 12 is fixed with Support block 13, several support blocks 13 have the sam...

Abstract

The invention provides a municipal well lid and a disassembling tool and an assembling and disassembling method thereof, and belongs to the field of municipal engineering equipment. The problem that an existing well lid is difficult to disassemble is solved. The municipal well lid comprises a chamber body and a lid body, and further comprises a plurality of supporting columns, a ring-shaped supporting plate and compression springs, wherein a baffle ring is arranged on the inner wall of the chamber body; the bottom ends of the supporting columns are fixed to the top surface of the baffle ring;a supporting block is fixed at the top end of each supporting column; a plurality of supporting holes are formed in the supporting plate; the supporting columns separately penetrate in the supportingholes; a sand-proof sleeve is fixed at the outer edge of the top surface of the supporting plate; each compression spring sleeves the corresponding supporting column; two ends of each compression spring are abutted to the top surface of the baffle ring and the bottom surface of the supporting plate; a fixing hole which penetrates through the top surface and the bottom surface of the lid body is formed in the center of the lid body; a plurality of disassembling holes are further formed in the lid body; and the supporting plate is positioned below the disassembling holes. By the well lid, the problem that the well lid is difficult to disassemble due to the fact that a gap is blocked by gravels can be avoided, and meanwhile, the well lid disassembling difficulty can be reduced by the disassembling tool.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering equipment, and relates to a municipal manhole cover, a dismantling tool and a dismantling method thereof. Background technique [0002] As an important part of the urban drainage system, the sewer pipe has become an important municipal engineering facility in urban construction. After the currently used well cover is installed and used for a period of time, the gap between the well seat and the cover body will be filled with silt, which makes it very laborious to open again. In severe cases, it cannot be opened or the well cover is damaged. [0003] The existing application number is 201620468375.5, which is a Chinese utility model patent named "Easy Maintenance Municipal Engineering Manhole Cover", which is provided with an annular sand-proof sleeve at the gap between the well seat and the cover body, and the sand-proof sleeve is fixed with the cover body. The bottom surface of the...
