Abstract

The invention relates to a method for installing a rain sewage well cover on an asphalt pavement, which comprises the following steps: (1) when the asphalt pavement is constructed, an annular groove is reserved around the well ring; (2) laying anti-settling reinforcing steel bars in the annular grooves; (3) the well lid is suspended by using the hoisting device, and the suspension height is adjusted until the height of the upper end surface of the well lid is consistent with the height of the road surface, so that the suspension state of the well lid is maintained; (4) and pouring concrete into the annular groove, curing, and removing the hanging device after the concrete reaches a preset strength. The invention has the advantages that: the method is simple in construction, the installed well cover is not settled, the well cover can pass through a vehicle with a large load, and the well cover is good in flatness and smooth to pass.

Description

Method for installing rain sewage well cover on asphalt pavement

Technical Field

The invention relates to a method for installing a rain sewage well cover on an asphalt pavement.

Background

The traditional method of the asphalt pavement rain sewage well cover is that after the base construction is finished, before the asphalt pavement construction, bricks, stones or concrete are used for lifting a well body well to a designed elevation, a well ring is placed, and then asphalt is paved. The technology has the advantages that the compaction degree of the asphalt cannot be controlled in advance, the well ring is often one or two centimeters higher or lower than the asphalt pavement, and is not flat, so that the vehicle cannot stably pass through the technology. And the well mouth can often be smashed by the vehicle, leads to the walling crib to sink or broken, influences the safety of passing.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a method for installing a rain sewage well cover on an asphalt pavement, and the technical scheme of the invention is as follows:

a method for installing a rain sewage well cover on an asphalt pavement comprises the following steps:

(1) when the asphalt pavement is constructed, an annular groove is reserved around the well ring;

(2) a lower civil grid layer, an anti-settling reinforcing steel bar and an upper civil grid layer are sequentially paved in the annular groove from bottom to top;

(3) the well lid is suspended by using the hoisting device, and the suspension height is adjusted until the height of the upper end surface of the well lid is consistent with that of the road surface, so that the suspension state of the well lid is maintained;

(4) and pouring concrete into the annular groove, covering the lower wood grid layer, the anti-settling reinforcing steel bars and the upper civil grid layer with the concrete, maintaining, and removing the suspension device after the concrete reaches a preset strength.

The distance between the outer edge of the annular groove and the walling crib is 30-50 cm.

The invention has the advantages that: the method is simple in construction, the installed well cover is not settled, the well cover can pass through an automobile, the flatness is good, and the passing is smooth.

Detailed Description

The invention will be further described with reference to specific embodiments, and the advantages and features of the invention will become apparent as the description proceeds. These examples are illustrative only and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications may be made without departing from the spirit and scope of the invention.

The invention relates to a method for installing a rain sewage well cover on an asphalt pavement, which comprises the following steps:

(1) when the asphalt pavement is constructed, an annular groove is reserved around the well ring;

(2) a lower civil grid layer, an anti-settling reinforcing steel bar and an upper civil grid layer are sequentially paved in the annular groove from bottom to top;

(3) the well lid is suspended by using the hoisting device, and the suspension height is adjusted until the height of the upper end surface of the well lid is consistent with that of the road surface, so that the suspension state of the well lid is maintained;

(4) and pouring concrete into the annular groove, covering the lower wood grid layer, the anti-settling reinforcing steel bars and the upper civil grid layer with the concrete, maintaining, and removing the suspension device after the concrete reaches a preset strength.

The distance between the outer edge of the annular groove and the walling crib is 30-50 cm.

Through the process, the installed well lid is not settled, can pass through a loaded automobile, and is good in flatness and smooth to pass.

Claims (2)

1. The method for installing the asphalt pavement rainwater and sewage well cover is characterized by comprising the following steps of:
