Supply of semi-automatic static level

Description :

　　Principle of static level

　　In the system of static level, the vertical displacement of all measuring points is relative to one of the reference points, and the vertical displacement of that point is relatively constant or can be accurately determined in other ways, so as to calculate the settlement change of each measuring point in the static level system. Features: Linear measurement, position output, non-contact continuous measurement, wear and tear, protection level IP65. The sensor does not require recalibration or regular maintenance. It has multiple input/output options, including voltage and current analog signal output, as well as RS485 digital signal output. Compared with other level transmitters and level gauges, it has obvious advantages in simple and convenient installation.

　　Main purpose of railway settlement monitoring

　　1. Obtain observation data on the load and natural settlement of the newly built 200-350km/h ballastless track subgrade.

　　2. By monitoring, obtain the true situation and deformation trend of settlement and deformation of different structures in the project.

　　3. By monitoring and understanding the dynamic changes in settlement during the compaction process of the roadbed, timely and reliable information can be provided for the later settlement, in order to evaluate the safety of the ballastless track foundation under load and natural settlement.

　　4. Provide forecasts for potential safety hazards in engineering, in order to take effective measures and prevent accidents from occurring.

　　Principle of Layered Settlement Gauge

　　Inductive sensor is a type of variable reluctance sensor that utilizes the change in inductance of a coil to achieve non electric measurement. He can convert various mechanical and physical parameters such as displacement, vibration, pressure, strain, flow rate, and specific gravity into electrical output, enabling long-distance transmission, display, and control of information. A simple inductive sensor application consists of an iron core and a movable armature. There is an air gap between the armature and the iron core. When the armature moves, the magnetic resistance of the air gap in the magnetic circuit changes, causing a change in coil inductance. This change in inductance corresponds to the position of the armature, that is, the size of the air gap. Therefore, as long as the change in inductance can be measured, the magnitude of the displacement of the armature can be determined. Inductive sensors are made based on this principle.

　　Installation and layout of layered settlement meter

　　① Before installation, connect multiple single point settlement meters in series based on the number of layers.

　　② Adopt drilling and drilling methods for burial, with a diameter of Φ 108 or Φ 127.

　　③ Drill vertically, the depth of the hole should be consistent with the total length of the settlement meter, and the hole opening should be flat.

　　④ Before installation, grout at the bottom of the hole to secure the bottom anchor plate 1.

　　⑤ During installation, the bottom anchor plate 1 is located below and the flange settlement plate 2 is located above.

　　⑥ At the same time, use a drawstring to protect the components from falling off on their own.

　　⑦ Use rod 3 to press the bottom anchor plate 1 of the settlement meter to the design depth.

　　⑧ Fill with fine sand or soil until the flange plate 2 is connected to the layer.

　　⑨ Grout at the connection flange plate 2 of the layer.
