No matter how well the preparatory work is done in the early stage, it can not completely avoid the problems of dynamic compaction foundation treatment. Especially, large-scale dynamic compaction construction and large-scale dynamic compaction construction are complex structures with huge volume. If there are no problems in the early inspection, unexpected problems may occur during the construction process. The following dynamic compaction machine rental manufacturer will explain the treatment method for you.
Sometimes, it is quite common for large-scale dynamic compaction construction to find that the track has fallen off. This kind of problem will appear briefly in the case of long-term use of large-scale dynamic compaction construction or aging of large-scale dynamic compaction construction. At this time, it is necessary to check the guide wheel of large-scale dynamic compaction construction to see if it is seriously worn. If it is seriously worn, it is necessary to replace the guide wheel.
What if the track becomes loose. The new crawler is very tight when it is installed, and it will become loose after a long time. In the daily inspection of large-scale dynamic compaction construction, it is necessary to pay attention to the tightness of the track at all times, because the track will simply fall down once it is loose. The crawler will be replaced when it is used for a long time, and only the pin sleeve needs to be replaced when it is used for a long time.
Interlocking board interlocking board is a layer of maintenance track. If the wear is severe, the maintenance function will be lost and it needs to be replaced directly. The construction of large-scale dynamic compaction is very simple, such as foundation treatment, track replacement and installation. Even if such problems occur, the on-site staff can solve them by themselves.
With the arrival of the rainy season, many lands have become collapsible loess or even silt. What are the measurement methods for large-scale dynamic compaction of collapsible loess in the foundation? Large-scale dynamic compaction can be used to treat collapsible loess in many projects, because it is intended to improve the bearing capacity of the foundation and reduce the compressibility of the soil layer. Moreover, this method is very convenient and quick to operate, saves money and investment, and has obvious advantages in reinforcement during construction.
Treatment method of Collapsible Loess:
1. There are many methods commonly used to treat collapsible loess, such as cushion method, plain soil cushion method, lime soil cushion method, etc. These different methods have different processes. For example, the cushion method is to treat the collapsible loess foundation locally or unilaterally. The thickness of the loess layer that can be treated is about one to three centimeters. This cushion method can meet the requirements of bearing capacity and water stability according to different construction methods. Select the whole lime soil cushion for treatment.
2. The other method is plain soil cushion method. Plain soil cushion method is the original drawing after foundation pit excavation. Water shall be sprayed for wetting first, and then a method of mechanical backfilling and layered backfilling shall be selected. It can be designed in height. It has a great relationship with the work of machinery, the moisture content of soil, the thickness of paving soil and so on.
