[0002] In the existing technology, settlement monitoring devices are used to monitor settlement during subway tunnel construction so that the construction safety can be controlled by analyzing the monitored data. Most of the existing settlement monitoring devices are static levels, which are installed on a mounting base set at a designated location to monitor settlement at that location.

[0003] Existing static levels typically use a screw rod to connect to a mounting base during installation. The position of the static level on the screw rod is adjusted according to installation requirements to achieve height adjustment relative to the mounting base, thus meeting the connection requirements with other monitoring equipment. However, the existing screw rod connection to the static level has the following problems: the screw rod and the static level are separate units, which are prone to loss during transportation and handling; the mounting base is usually small and installed on the wall inside the tunnel, leaving little operating space; and the separate screw rod design makes installation inconvenient for one person, requiring multiple people to cooperate, which is quite inconvenient. Therefore, there is an urgent need for a shield tunneling settlement monitoring device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a settlement monitoring device for shield tunneling construction. By integrating the screw rod with the static level instrument body using a housing sleeve, the installation convenience of the static level instrument body can be improved, the loss of the screw rod during transportation and transfer can be avoided, and the entire monitoring device can be made neater and more aesthetically pleasing.

[0005] The present invention adopts the following technical solution:

[0021] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0022] like Figures 1 to 4 As shown, the present invention discloses a settlement monitoring device for tunnel boring machine (TBM) construction, comprising a hydrostatic level body 1 and a mounting base. Multiple receiving sleeves 3 are spaced apart on a flange 2 at the bottom of the hydrostatic level body 1. Preferably, three receiving sleeves 3 are arranged at equal intervals along the flange 2. Each receiving sleeve 3 is rotatably connected to the flange 2, and each receiving sleeve 3 has a threaded screw 4 threaded inside, which movably passes through the flange 2. A fixing bolt 5 is threaded on the flange 2 below the screw 4 for fixing to the mounting base. Multiple fixing bolts 5 can be provided as needed, so that two fixing bolts 5 are respectively fixed to the upper and lower ends of the mounting base during installation. In use, different receiving sleeves 3 can be rotated to control multiple screws 4 to extend by the same distance. Then, the fixing bolts 5 are used to connect the screws 4 to the mounting base, thus installing the hydrostatic level body 1. When rotating the receiving sleeves 3, one hand should hold the screw 4 to prevent it from rotating synchronously with the receiving sleeves 3, which would affect the normal extension of the screw 4.

[0023] Furthermore, the flange 2 has an adjustment hole for the screw 4 to pass through, and a limit block is protruding in the adjustment hole. The screw 4 has a limit groove 6 that matches the limit block along its axial direction. Through the sliding contact between the limit block and the limit groove 6, the screw 4 can be stably moved out of the housing sleeve 3 along the axial direction, avoiding synchronous rotation with the housing sleeve 3 during adjustment, and eliminating the need for manual holding of the screw 4 during adjustment, thus improving the convenience of operation.

[0024] Furthermore, the bottom of the receiving sleeve 3 is provided with an internal thread that matches the screw 4. The inner diameter of the receiving sleeve 3 at the upper part of the internal thread is larger than the diameter of the screw 4. The connection with the screw 4 is achieved only through the internal thread at the bottom of the receiving sleeve 3, which can improve the convenience of adjusting the screw 4. In addition, by making the receiving sleeve 3 a transparent structure, it is easy to observe the distance moved by the screw 4, thereby providing a reference for adjusting multiple screws 4 at the same distance. Preferably, the receiving sleeve 3 is provided with scale lines to further improve the accuracy of the displacement of the screw 4 and the consistency of the position of multiple screws 4 after adjustment.

[0025] Furthermore, a limiting plate 7 is provided on the screw 4 above the fixing bolt 5. The size of the limiting plate 7 is larger than the size of the mounting hole 8 opened on the mounting base, so as to limit and support the screw 4. The screw 4 below the limiting plate 7 passes through the mounting hole 8 and is fixed to the bottom of the mounting hole 8 by the fixing bolt 5, so as to achieve a tight connection between the screw 4 and the mounting base. At this time, only one fixing bolt 5 can be set, which can be located at the bottom of the mounting base when in use.

[0026] Furthermore, in this embodiment, the mounting base includes a fixing plate 9 with fixing holes 10 for mounting the fixing plate 9 to the tunnel wall. Support plates 11 are provided on both sides of the fixing plate 9, and a mounting plate 12 is slidably disposed between the two support plates 11. Mounting holes 8 are formed on the mounting plate 12. The fixing holes 10 and mounting holes 8 are preferably elongated holes to allow for fine-tuning of their positions during installation. The sliding arrangement of the mounting plate 12 between the two support plates 11 facilitates the installation of the static level instrument body 1 in confined spaces after the fixing plate 9 is installed on the tunnel wall, providing operating space and further improving the convenience of installation. Simultaneously, it allows for matching and adjustment based on the position of other monitoring equipment connected to the static level instrument body 1, improving connection convenience and reducing the risk of cable and pipe twisting after connection.

[0027] Preferably, each support plate 11 is fixedly equipped with a rotating shaft 13, which is rotatably connected to an ear plate 14 mounted on a fixed plate 9. The rotating shaft 13 passes through the ear plate 14, and at least one end of the rotating shaft 13 has an inwardly axially recessed groove 15. A positioning cap 17 is connected to the groove 15 by a spring 16. The end face of the positioning cap 17 that contacts the ear plate 14 is provided with a meshing positioning gear 18. The meshing of the two positioning gears 18 can limit the rotation of the rotating shaft 13, ensuring the stability of the support plate 11 after adjustment. When the support plate 11 needs to be adjusted, the positioning cap 17 is pulled outward, causing the positioning gear 18 to disengage from the positioning gear 18 on the ear plate 14. At this time, the limitation of the rotating shaft 13 is released. After the support plate 11 is rotated and adjusted, the positioning cap 17 is released and reset under the restoring force of the spring 16. The two positioning gears 18 mesh and reposition. The rotatable adjustment of the support plate 11 can compensate for the tunnel wall of the mounting plate 9 being non-vertical. By finely adjusting the position of the support plate 11, the mounting plate 12 can be kept in a horizontal state, ensuring that the position of the static level body 1 does not deviate.

[0028] Both sides of the mounting plate 12 are provided with sliding grooves 19 along its length. A slider 20 protrudes from the support plate 11 and slides in contact with the sliding grooves 19. A positioning rod 21 is elastically provided on the outer side of the support plate 11, passing through the slider 20. A fixing tooth is provided at the end of the positioning rod 21. A rack plate 22 that meshes with the fixing tooth is provided on the inner wall of the sliding groove 19. The positioning rod 21 and its end fixing tooth can fix the position of the mounting plate 12, ensuring its stability during operation. Furthermore, the front end of the mounting plate 12 is provided with a receiving hole 23, in which a spirit level 24 is embedded, for visually determining whether the mounting plate 12 is level, thereby reducing deviations in the measurement data during the operation of the hydrostatic level instrument 1.

[0029] When using this utility model, first install the fixing plate 9 at the designated position, then assemble the static level body 1, and adjust the receiving sleeve 3 according to the installation requirements to control the multiple screws 4 to extend the same distance. Finally, use the fixing bolts 5 to fix the screws 4 on the mounting plate 12. The structure is simple, the operation is convenient, and the practicality is strong.
