A method and structure for quickly replacing a road inspection well cover seat

Abstract

The invention discloses a method and a structure for rapidly replacing a highway inspection well cover base. When a damaged well cover base on a cement highway or an asphalt highway is replaced, firstly a road surface cutter is used for cutting along the peripheral road surface which is 20-100mm away from the edge of the damage well cover base, after cutting is finished, cut road surface residues at the peripheral of the damaged well cover base can be removed and simultaneously the damaged well cover base is removed; then a new well cover base, which has the same size with the damaged well cover base, is placed at the position of the original damaged well cover base, and thus a circle of concave ring groove is formed between the new well cover base and the road surface of the cement highway or the asphalt highway; and finally a high-strength polyester composite material is filled into the concave ring groove, so that the new well cover base and the cement highway or the asphalt highway are connected into a whole by virtue of the high-strength polyester composite material. The method and the structure have the advantages of log construction period, low construction cost, convenience in operation, longer service life of the well cover base after replacement, and the like.

Description

technical field [0001] The invention relates to a method and structure for quickly replacing a road inspection well cover seat, belonging to the technical field of road inspection well maintenance. Background technique [0002] The manhole cover or the manhole cover seat of the inspection well on the cement road or the asphalt road is often damaged. At present, when the manhole cover is only damaged, its replacement is more convenient. Just remove the damaged manhole cover and replace it with a new manhole cover. But when the well cover seat is damaged, please replace the work of the well cover seat is just more troublesome. Generally, the manhole cover is replaced by means of fence, taking the manhole cover from the breach, changing the manhole cover, waiting for construction (including pouring concrete pavement or asphalt pavement), and maintenance. The replacement construction period of a manhole cover is generally more than 7 days , this traditional construction method ...

Problems solved by technology

[0002] The manhole cover or the manhole cover seat of the inspection well on the cement road or the asphalt road is often damaged. At present, when the manhole cover is only damaged, its replacement is more convenient. Just remove the damaged manhole cover and replace it with a new manhole cover. But when the well cover seat is damaged, please replace the work of the well cover seat is just more troublesome. Generally, the manhole cover is replaced by means of fence, taking the manhole cover from the breach, changing the manhole cover, waiting for construction (including pouring concrete pavement or asphalt pavement), and maintenance. The replacement construction period of a manhole cover is generally more than 7 days , this traditional construction method not only has the shortcomings of long construction period, time-consuming and labor-intensive work, but also has problems such as high replacement cost and great impact on urban road traffic, especially for roads with heavy traffic. construction

In addition, when using the existing method to replace the manhole cover seat, because the expansion coefficient of the replaced manhole cover seat is inconsistent with the cement pavement or asphalt pavement, after a period of use, the manhole cover seat and the surrounding cement pavement or asphalt pavement There will be a larger and larger gap between them, so that under the rolling of the car, the manhole cover seat will receive more and more impact, and the manhole cover seat will be damaged in a short period of time

Therefore, the existing way of replacing the road manhole cover seat is still not ideal enough, and still cannot meet the needs of use.
