Description

Technical Field

[0001] This utility model belongs to the field of foundation settlement monitoring, and in particular relates to a total station prism device. Background Technology

[0002] In soft soil foundation treatment engineering, vacuum preloading is widely used as an effective foundation reinforcement technology. Its characteristic is that it involves installing drainage boards and sealing membranes in the soft soil foundation, and using vacuum pumps to extract moisture and air from the foundation, thereby achieving the purpose of foundation reinforcement. To ensure the effectiveness of vacuum preloading, the selection and arrangement of monitoring devices are crucial. Traditional monitoring methods mainly rely on small prisms at fixed locations combined with total stations or levels for observation. However, in situations involving complex terrain or frequent adjustments to monitoring points, their flexibility and adaptability are insufficient.

[0003] Existing vacuum preloading monitoring devices are not adjustable, and their application in soft soil treatment projects will face many limitations. For example, in areas with large slopes, undulating surfaces, or uneven settlement, fixed monitoring points may not be able to fully cover key areas, resulting in incomplete monitoring data or blind spots, which will affect the accurate assessment of the foundation reinforcement effect.

[0017] Figure 2 This is the front view of the present invention. Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] This utility model discloses a total station prism device, such as... Figure 1 and Figure 2As shown, the system includes a settlement plate 1, a lifting rod 5, a connector 6, and a total station prism. In actual use, the settlement plate 1 is laid on the foundation, and the lifting rod 5 is installed on the settlement plate 1. The lifting rod 5 is preferably a hydraulic rod. The connector 6 is detachably connected to the movable housing of the lifting rod 5. The total station prism is installed on the connector 6. By adjusting the height of the lifting rod 5, the height of the total station prism can be adjusted at one time. By adjusting the connection position between the connector 6 and the lifting rod 5, the height of the total station prism can be further adjusted. In actual use, the height of the total station prism can be adjusted according to the conditions or needs of the construction site.

[0020] The connector 6 is equipped with a support plate 8 for supporting the total station prism, and the support plate 8 is in a horizontal state to ensure the effectiveness and accuracy of the total station prism monitoring.

[0021] A protective chamber 9 is installed on the support plate 8, positioned around the prism to protect the total station prism. The side of the protective chamber 9 corresponding to the monitoring lens of the total station prism is an open structure. Preferably, the protective chamber 9 is a closed structure and is made of transparent material. The protective chamber 9 reduces the impact of the construction site environment on the total station prism.

[0022] Preferably, the connector 6 is a clamp, and the connecting lug of the clamp is threaded with a high-strength bolt 7 to fix it to the lifting rod 5; and the support plate 8 is fixedly connected to one side of one of the clamps.

[0023] A hollow fixing tube 2 is detachably installed at the center of the settlement plate 1, and the fixing part of the lifting rod 5 is fixedly connected to the inner wall of the hollow fixing tube 2. Multiple L-shaped fixing plates 3 are arranged in a ring array on the settlement plate 1, and these fixing plates 3 fix the hollow fixing tube 2 to the settlement plate 1. Multiple bolt through holes are provided on the fixing plates 3, and fixing screw holes matching the bolt through holes are provided on the hollow fixing tube 2 and the settlement plate 1. The vertical plates of the fixing plates 3 are connected to the hollow fixing tube 2 by fixing bolts 4, and the horizontal plates of the fixing plates 3 are connected to the settlement rod by fixing bolts 4. The thickness of the fixing screw holes on the hollow fixing tube 2 is less than the wall thickness of the hollow fixing tube 2, which prevents the fixing bolts 4 from extending into the interior of the hollow fixing tube 2 and damaging the lifting rod 5; the thickness of the fixing holes on the settlement plate 1 is less than the thickness of the settlement plate 1, which prevents the fixing bolts 4 from extending below the settlement plate 1 and directly contacting the foundation.

[0024] In actual use, during transportation, the connector 6 is separated from the lifting rod 5, and the fixing plate 3 and hollow fixing pipe 2 are separated from the settlement plate 1 to facilitate overall transportation. After arriving at the construction site, the settlement plate 1 is first laid, and then the hollow fixing pipe 2 is fixed to the center of the settlement plate 1 using the fixing plate 3 and fixing bolts 4. Then, the connector 6 is installed on the movable part of the lifting rod 5 using high-strength bolts 7. During use, the height of the connector 6 is adjusted as needed, which is also the height of the total station prism.
