The group always starts from convenience and practicability, and fully considers the rationality, stability and operability of the construction technology, materials and design of the well cover.

The material has good road performance in terms of construction workability and durability, which can further strengthen the connection between the well cover and the road structure, delay settlement, and effectively prolong the service life of inspection wells and urban roads, Make it better solve the “persistent disease” of urban road inspection wells.

Xie Wei, deputy secretary of the Party committee and general manager of the group, Zhao Zhanghua, assistant general manager, and relevant departments came to the scene to observe.

There is a common and tough color called “Luqiao orange” official account.

The group will continue to improve the process and further apply and promote new technologies and processes through cross departmental cooperation and exchange.

At the same time, he pointed out that the new process of the cast manhole cover meets the requirements of “specialization and innovation”.

The new technology of well cover uses the “four new” technology to deal with the diseases such as settlement of urban road inspection well and damage near the well; To solve the problems existing in the lifting of urban road manhole cover, such as high difficulty of standardized operation, low accuracy of elevation control, insufficient density of horizontal slurry, difficult to ensure strength and so on.

The follow-up exploration and practice process is still very complicated.

It is worth mentioning that the group will transform the self-adjusting anti settlement well cover, and use the “and paving” winter asphalt cold patching material for on-site construction.

Our maintenance work needs to be guided, and the maintenance team also needs to do a good job in technical and standardized operation, so as to boost morale and enhance team cohesion.

After observing the standardized operation of the manhole cover, general manager Xie Wei fully affirmed the good performance in the operation.

The quality of technology directly affects the flatness of pavement and driving comfort.

In order to finely implement the road engineering construction of “welcoming the Asian Games” and help improve the quality of the road construction of the Asian Games, all departments of the group communicated with each other and conducted a rapid improvement process demonstration in Shitang park.

The problem is that the traffic load and the number of heavy vehicles are increasing day by day, there is often abnormal noise when driving, and there are often diseases such as uneven settlement and cracking around the well.

The traditional self-adjusting anti settlement well cover is generally used for the lifting of the existing well cover.
