With the continuous development of engineering technology, construction has its due position in many industries, especially the filling of road subgrade needs dynamic compaction foundation construction to ensure the use of the road. This is a more practical method to ensure the dynamic compaction effect. Let's talk about how to apply the dynamic compaction foundation construction method in road subgrade filling.
1. Determine the technical parameters
In the construction of dynamic compaction, the debris without weeds should be selected in the selection of subgrade filler. In addition, the road should be layered, the surface soil should be clean and tidy, and the less weathered sandstone should be used. Backfill can ensure good results. Before road construction, it is necessary to tamp the foundation and the structure of dynamic compaction until the penetration and uplift height meet the requirements.
2. Preparation of construction machinery
The selection of mechanical equipment in dynamic compaction construction will affect the effect of road filling, and the preparation of machinery will affect the efficiency and quality of construction, so we should pay attention to this link in the construction process. As an aviation hammer and crane. Both of them are important factors to complete the road engineering, and the decoupling device can make the hammer fall smoothly to ensure the normal construction.
3. Technical preparation of workers
The skill of workers is an important part of the whole road filling project. It is closely related to the skills of workers that which is beneficial to the construction of dynamic compaction foundation. Technicians can make a comprehensive study of the engineering geological report, and carry out low-tech testing when they participate in the construction work, so that they can make clear the quality standards and safety measures. They must carry out corresponding training before taking up their posts to understand the construction method of dynamic compaction. Ensure the normal construction.
In a word, dynamic compaction construction is a more practical method in road subgrade filling. In order to ensure the effect of dynamic compaction, it is necessary to determine the technical parameters and prepare the construction machinery. Construction personnel also need to understand the relevant technical points, and use them reasonably in the actual road engineering, so as to ensure the control of construction quality and improve the bearing capacity of subgrade.
