The elasticity of the second spring 504 causes the clamping rod 5 to return to its original position, so that the clamping rod 5 is inserted into the socket on the plug block 401, thereby limiting the plug block 401 and further realizing the installation of the protective cover 4.

[0033] When in use, the small prism and the total station are matched with each other to monitor the settlement of the vacuum preloaded foundation. After the small prism is used, the protective cover 4 can be used to protect the small prism.

[0034] When installing the protective cover 4, the control block 502 is manually operated to move so that the clamping rod 5 is temporarily in the storage state, and then the plug block 401 on the protective cover 4 is inserted into the slot on the L-shaped bracket 201, and then the control block 502 is released, and the elasticity of the second spring 504 makes the clamping rod 5 return to its original position, so that the clamping rod 5 is inserted into the jack on the plug block 401, thereby limiting the plug block 401 and further realizing the installation of the protective cover 4;

[0035] When removing the protective cover 4, the control block 502 is manually operated to move so that one end of the clamping rod 5 is moved out of the insertion hole on the insertion block 401, thereby releasing the limit of the insertion block 401, and then the protective cover 4 can be removed;

[0036] When removing the small prism, the adjusting block 305 is manually operated to move so that one end of the insertion rod 3 is removed from the slot on the mounting block 203, thereby releasing the clamping of the mounting block 203, and then the small prism can be quickly removed.

[0037] To summarize, the vacuum preloading foundation settlement monitoring device, by setting the insertion rod 3, displacement plate 301, vertical rod 302, top plate 304 and adjustment block 305, manually operates the adjustment block 305 to move, so that one end of the insertion rod 3 is moved out of the slot on the mounting block 203, thereby releasing the clamping of the mounting block 203, and then the small prism can be quickly removed, thereby realizing the function of quickly removing the small prism, and there is no need to find tools for disassembly during the disassembly process, and the disassembly efficiency is high. By setting the protective cover 4, when the small prism is used, the protective cover 4 can be installed on the L-shaped bracket 201, so that the small prism can be placed in a closed space to prevent it from being exposed to the external environment for a long time, thereby reducing the risk of contamination and effectively protecting the cleanliness and integrity of the small prism.
