　　The settlement plate is composed of steel plates, measuring rods, and protective sleeves. The size of the base plate can be customized according to customer requirements. The measuring rod and the base plate are fixed in a vertical position, and the protective sleeve is made of steel pipe sleeve. The sleeve size is suitable to cover the measuring rod and allow the ruler to enter the measuring head. As the filling height increases, the measuring rod and sleeve are also correspondingly raised, with each section not exceeding 55cm in length. After raising, the top surface of the measuring rod should be slightly higher than the upper opening of the sleeve. When not measuring, seal the upper opening of the casing with a cap to prevent the filler from falling into the pipe and affecting the sinking of the measuring rod.

　　settlement observation

　　By observing, organizing, and drawing the process line of foundation settlement time load, the filling rate of the roadbed can be effectively controlled to ensure its stability and prevent roadbed instability. This work will be implemented throughout the entire contract section by qualified units of the project department.

　　The frequency of roadbed settlement observation shall not be lower than the provisions in the table below. When environmental conditions change (such as continuous rainfall or continuous drought) or data anomalies occur, timely observation should be carried out.

　　Before installation, the roadbed surface must be compacted, and the installation position must be measured. Once the position is fixed, the bottom elevation of the slab should be measured immediately, and this value should be recorded as the initial value.

　　After filling the height beyond 20cm of the observation rod mouth, compact the entire section, and then extend the measuring rod and protective sleeve of the settlement plate. The extension method can be threaded connection or welding connection (measuring rod welding, protective sleeve connection with adhesive tape). After connection, immediately measure the elevation and calculate the actual connection length.

　　(1) Place the settlement plate flat in the pit, fill the surrounding area with yellow sand and calibrate the level with a level, and then backfill the soil to level and compact it.

　　(2) Dig a soil pit of about 500 × 500 × 500mm at the burial site, and level and compact the pit with 30-50mm thick yellow sand.

　　Although most traders have not yet returned to the market, during the Spring Festival holiday, external prices have risen. In addition, some steel companies in the north have restricted production and reduced supply, leading to strong sentiment of price increases among merchants. As a result, steel billet prices have risen first, and the coated sheet market has generally risen. However, due to the fact that end users have not yet resumed work, there are few transactions. Tomorrow is the eighth day of the lunar new year, and the number of merchants returning to the market for business is increasing. It is expected that there will still be room for the price of coated panels to rise tomorrow. In terms of steel mills, the ex factory price of galvanizing for private steel mills in northern China has generally increased by 100 yuan, while the ex factory price of cold-rolled base material plants in Hanxing area has increased by 70-100 yuan, with today's price at 4950 yuan.
