Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0028] A road inspection well, which is composed of a well cover 5, a well base 4 and a well shaft 3, the well base is coaxially fixed on the upper end of the well shaft, and the well cover is coaxially installed on the well base; the excavation surface between the outside of the well shaft and the structural layer is used Concrete 2 is replaced and poured together with the wellbore and the top surface is flush. On the top of the wellbore top is the asphalt pavement 1, the well seat is arranged in the asphalt pavement, and the top surface of the well cover is flush with the asphalt pavement.

[0029] The innovation point of the present invention is:

[0030] The wellbore is a reinforced concrete stru...

Abstract

The invention relates to a road inspection well and a construction method thereof. The road inspection well comprises a well lid, a well seat and a shaft. The well seat is coaxially fixedly mounted at the upper end of the shaft. The well lid is coaxially mounted on the well seat. An asphalt road surface is disposed on the upper portion of the top surface of the shaft. The well seat is disposed in the asphalt road surface. The top surface of the well lid is parallel with the asphalt road surface. The shaft is of a reinforced concrete structure, that is to say, a reinforcement cage is disposed in the shaft, and bolts are coaxially and evenly pre-buried in the wall of the shaft at intervals. The pre-buried bolts penetrate the nut holes of the well seat and fixedly connected by nuts. The road inspection well has the advantages that the shaft below the well lid is made of reinforced concrete, the bolts are pre-buried in the shaft, the well seat and the shaft are fixedly and integrally connected by the bolts, and cracks between the periphery of the well lid and the road surface are avoided effectively.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and relates to a manhole cover for an inspection well on a road, in particular to a road inspection well and a construction method thereof. Background technique [0002] With the continuous development of urban roads, the maintenance pipe enclosure of inspection well covers on the road is becoming more and more prominent. Traffic safety accidents caused by cracking and damage between the well cover and the road surface are not uncommon due to the displacement and damage of the manhole cover. At present, the connection mode between the inspection well cover on the existing road and the lower shaft (or shaft diameter) generally all is to directly do slurry under the inspection well cover to stabilize the well cover, and then pave the asphalt concrete. Since this connection method cannot stably and effectively connect the manhole cover and the surrounding road structure, under the long-term acti...
