Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0023] A kind of maintenance technology of national road manhole cover, comprises the following steps:

[0024] Step 1. Cut the circle; determine the diameter of the cut circle according to the disease of the old manhole cover. The principle is to try not to damage the original stable and flat old road surface; the circle cutting process can be carried out on the manhole cover with the disease in advance, which can shorten the time for installing the manhole cover and effectively guarantee The temperature of asphalt concrete; round cutting machine can choose manhole cover round cutting machine or tile cutting machine;

[0025] Step 2, chisel out the old manhole cover; choose a pneumatic pick, electric pick or rock drill to take out the old manhole cover and the manhole cover seat, trim and clean the base layer, and place a mold to preven...

Abstract

The invention discloses a maintaining technology for a national highway inspection well cover. The maintaining technology comprises the following steps of 1, circular cutting; 2, removal of an old well cover through chiseling; 3, spraying of emulsified asphalt, wherein a proper amount of the emulsified asphalt is sprayed on the contact surface of the inner wall of a round hole and a base layer; 4,leveling of a prefabricated member; 5, filling with asphalt concrete layer by layer, and compaction of the asphalt concrete; 6, completion and opening to traffic. According to the technology, the time for on-site pavement operation is short, the quality of the fabricated member is good and controllable, the prefabricated member is made and cured indoor, the interference factor is low, and factorization, industrialized, standardized and large-scale production of the prefabricated member is adopted, the cost is saved, and the quality is ensured. Excavation faces are reduced. The technology is relatively weak in compactness sensitivity while a traditional technology is high in compactness sensitivity, the compactness is not prone to damage, and according to the technology, two stable supporting faces are formed by a stable old pavement and the prefabricated member.

Description

technical field [0001] The invention relates to the field of road maintenance, in particular to a maintenance process for inspection well covers of national highways. Background technique [0002] National highway traffic main road, the average daily traffic flow is huge, the speed of passing vehicles is fast, there are many large vehicles, and the maintenance risk is high. Over the years, some rainwater and sewage manhole covers on the national highway have problems such as overall sinking, cracks around, and manhole cover guide noise. This problem seriously affects the traffic conditions of the road, the overall appearance and the life of residents. In order to eliminate hidden dangers and dangers, we will further strengthen the quality improvement of manhole covers and improve the overall level of the road. At present, there are two main traditional techniques for manhole cover replacement, one of which is to use double The fast cement is cast on site at the construction...
