Bayannur Settlement Plate Factory offers a full range of specifications for roadbed settlement plates

Description :

　　① The burial position of the settlement plate should be determined according to the design measurement. A 10cm sand cushion layer can be placed at the burial position to ensure that the measuring rod is perpendicular to the ground during burial. ② After placing the settlement plate, backfill a certain thickness of cushion layer, and then cover it with a protective sleeve. The protective sleeve should be slightly lower than the settlement plate measuring rod, and the upper opening should be covered to seal the pipe mouth. Corresponding filling sleeves should be filled around it to complete the burial work of the settlement plate. ③ The elevation reading of the top of the settlement plate measuring rod buried in place is taken as the initial reading. As the roadbed filling construction gradually increases, the settlement plate measuring rod and protective sleeve are raised. The appropriate height for each extension is 0.5m, and the change in the top elevation of the measuring rod before and after extension determines the amount of extension. Subway construction has an impact on the surrounding environment, and a detailed investigation of the surrounding construction environment should be conducted before construction. The main investigation items include the distribution of underground pipelines affected by construction, the surrounding buildings, and the overview of surface water sources near the construction site. The key contents of the investigation include the relative position relationship between the construction subway line and the pipeline, the purpose of the pipeline, the type and depth of the foundation, and the construction age of the building.

　　When designing a bridge, the step is to investigate hydrogeological data, including historical water levels, water flow velocities, etc. By forming curves and calculating hydrological conditions under various probabilities, the resistance capacity of the bridge can be determined according to its design positioning, such as withstanding floods that occur once every 50 years, once every 100 years, or once every 200 years. After clarifying this, search for specifications, determine various load coefficients, multiply the actual load by the corresponding coefficients, and obtain the basic design data before starting to design bridge foundations, such as piles, abutments, piers, etc.
