Problems solved by technology

In this invention, a spring is arranged between the upper cover and the lower cover. When the vehicle rolls over the upper cover, because the upper cover first contacts the spring, it will cause the upper cover to move down, forming an unstable state, which will affect vehicle operation

Embodiment Construction

[0024] Such as figure 1 As shown, a shock-absorbing and anti-warping inspection well cover includes a well seat edge 1, a well seat body 2, a well cover body 3, a through hole 4, a metal block 5, a leaf spring 6, a support plate 7, a well cover counterbore 8, and a screw 9. Well cover protrusions 10, well seat grooves 11 and blocked screw holes 12.

[0025] Such as figure 2 As shown, the well base 1, the well base body 2, the well base groove 11 and the unconnected screw hole 12 form the inspection well base, and the well base body 2 is made of cast iron, which is circular in shape and has an outer diameter of φ500~1200mm, inner diameter is φ300~1000mm. The well block side 1 is processed on the outer edge of the well block body 2, the side width of the well block side 1 is 100-300mm, all of which are embedded in the surrounding foundation, the bottom of the well block side 1 is the foundation, and the top is asphalt concrete. When a vehicle or a pedestrian collides with a ...

Abstract

The invention discloses a damping and tilting-preventing inspection well cover. The damping and tilting-preventing inspection well cover comprises an inspection well cover base, a well cover, dampers and screws, wherein the inspection well cover base comprises a well cover base edge, an annular well cover base body, a well cover base groove and blind screw holes, the well cover base edge is arranged at the outer edge of the well cover base body and embedded into a surrounding base, the well cover base groove is arranged in the inner side of the well cover base body, and the blind screw holes are evenly distributed in the well cover base groove; the well cover comprises a well cover body, through holes, well cover counter bores and a well cover protrusion, the through holes are evenly distributed in the well cover body, the well cover protrusion is arranged at the edge of the lower bottom surface of the well cover body, the well cover counter bores are evenly distributed in the well cover protrusion, and the plurality of dampers are evenly circumferentially distributed on the inner side of the well cover protrusion; the well cover is integrally fastened to the inspection well cover base through the screws. The damping and tilting-preventing inspection well cover has the advantages that the inspection well cover is simple in structure and convenient to use; when the inspection well cover is used, vibration can be reduced, the surrounding base can be protected, and tilting of the inspection well cover can be prevented.

Description

technical field [0001] The invention relates to inspection well covers on roads, in particular to a shock-absorbing and anti-lifting inspection well cover. Background technique [0002] With the development of social economy, people's living standards continue to improve, and the number of vehicles running on the streets and alleys continues to increase; at the same time, urban infrastructure continues to improve, such as water supply, drainage, electrical, heating and communication facilities. The ground is replaced by underground laying, which leads to a large number of manhole covers distributed in the streets and alleys on the ground. When a moving vehicle presses on the manhole cover, the manhole cover will produce impact vibration, and the vibration of the manhole cover will make the surrounding area supporting the manhole cover Cracks in infrastructure, repeated rolling, cracks increase, lead to foundation collapse, inspection manhole cover tilt or overall collapse, r...
