[0002] When planning a railway beam yard, beam manufacturing and storage areas must be set up. The prefabricated box beams will be stored in the manufacturing and storage areas for a period of time before being erected. The weight of a single box beam reaches 800t, which requires settlement monitoring of the pedestals to ensure that the relative settlement difference of the four pedestals is no more than 2mm.

[0003] At present, the settlement monitoring of beam manufacturing and storage pedestals through traditional manual measurement has the following disadvantages: 1) The area of ​​beam manufacturing and storage in railway beam yard is large, and the labor intensity of manual measurement is high; 2) There are certain errors in reading data by manual measurement, and the settlement monitoring benchmark points are also prone to errors, which will affect the monitoring of pedestal settlement; 3) When the beam storage area reaches the peak of beam storage, a double-layer beam storage method is adopted. At this time, it is not easy to observe the benchmark points by manual measurement. Summary of the invention

The line groove passes from the liquid storage table through four pedestals and a reference seat to one side of the collection box to avoid exposure. The protective cover structure includes an upper shading plate and a lower shading plate. Seat plates that fit the pedestal or the reference seat are respectively arranged on the upper shading plate and the lower shading plate. The seat plates are fixed to the pedestal or the reference seat by two expansion bolts. Slots are respectively opened on the opposite surfaces of the upper shading plate and the lower shading plate.
