A subgrade settlement plate is a device used to monitor the settlement of a road subgrade, usually consisting of one or more steel or plastic pipes perpendicular to the surface of the road. When the subgrade of the road settles, the settling plate will sink with it, and the settlement of the subgrade can be calculated by measuring the displacement of the settling slab.
When choosing a subgrade settling slab, its width and thickness need to be considered. The width is usually determined according to the width and design requirements of the road, while the thickness is selected according to the grade of the road, soil conditions, and design requirements.
In general, thicker settling plates can provide better stability and load-bearing capacity, but they can also increase the cost and difficulty of construction.
When installing and using the subgrade settlement plate, the following points need to be noted:
1.Before installation, the foundation should be leveled and tamped to ensure the stability of the foundation and avoid the movement or tilting of the settling plate during installation and use.
2.The installation should be positioned and fixed according to the design requirements to ensure the verticality and stability of the settling plate.
3.In the process of use, regular monitoring and maintenance should be carried out to find and deal with problems in time to ensure the accuracy and reliability of monitoring data.
In short, choosing the appropriate width and thickness of the subgrade settlement plate is one of the important factors to ensure the safety of road construction and operation. Various factors should be fully considered in the process of selection and use to ensure the stability and reliability of the settling plate.
