What problems should be paid attention to in road engineering construction

The road construction project is a basic construction and the annual investment in this area is very large. Roads need to be built where there are no roads, and roads need to be maintained where they have already been built. In short, road construction is always under way. This is a huge task. During the construction of road projects, some problems need to be paid attention to. These include the following aspects.

道路工程施工应该注意哪些问题.jpg

First, the road should be constructed according to the construction specifications. The Highway Maintenance Code is a very important normative document for road maintenance. All the issues relating to road maintenance can be found here. Maintaining roads in accordance with the regulations can improve the quality of road maintenance and at the same time effectively ensure the safety of construction. Therefore, it is necessary to understand these normative documents before the road maintenance, so as to better complete the road maintenance work.

Second, we must pay attention to safety during the construction process. During the construction of road works, attention should be paid to safety issues. For example, the safety of equipment should be taken care of and safety must be paid when handling things. The construction of road projects will encounter many problems, such as landslides in the mountains, splashing of stone dust, etc., which will affect the safety of construction. For safety construction, appropriate protective measures should be taken to reduce the risk of construction.

Third, do maintenance and repair of construction vehicles. The construction of road projects will inevitably lead to the use of special maintenance vehicles. This kind of professional vehicles will wear out during use, and should do a good job of maintaining the vehicles, including the functions of the vehicles, and the problems of the vehicles themselves, as well as the maintenance of good projects. Special vehicles can have handy tools at work to improve the efficiency of road maintenance.

Fourth, pay attention to the construction quality assurance. The quality of highway construction is very important, and it is related to the safety of road use. In order to guarantee construction quality, there should be a third-party supervision to check the construction quality and sign the relevant procedural documents. From the institutional point of view, it should be ensured that the construction is standardized and the construction quality of road projects be guaranteed.


Batch Waste Plastic Pyrolysis Plant

Pyrolysis Plant is used for recycling waste tire, waste plastic, waste rubber to fuel oil. According to the actual situation in every country and district, we developed different models of Batch Pyrolysis Plants for waste tires, rubber and plastic with daily capacity 5 -10 tons.
