Description

Technical Field

[0001] This utility model relates to the field of bridge and tunnel construction technology, specifically to a soil settlement detection device used in bridge and tunnel construction. Background Technology

[0002] In tunnel construction, especially when using underground excavation methods such as shield tunneling, soil settlement directly affects the stability of the tunnel roof and surrounding soil. Excessive soil settlement beyond control can lead to serious safety accidents such as tunnel collapse and ground subsidence. Real-time settlement monitoring allows for early detection of abnormal settlement trends, enabling timely adjustments to construction parameters (such as the tunnel boring machine's advance speed and excavation volume) and the implementation of corresponding reinforcement and support measures to ensure the safety of construction personnel and the smooth progress of construction. Leveling is a commonly used method for detecting soil settlement.

[0003] Leveling is a traditional and commonly used surveying method. Based on the basic principles of leveling, a level instrument is used to establish a horizontal line of sight. The elevation difference between two points is determined by reading the leveling rods erected at different measuring points (settlement observation points are pre-arranged in the area where soil settlement needs to be monitored). After multiple observations and comparison of changes in elevation difference, the settlement amount at each observation point is obtained. However, the level instrument and its supporting bracket used in current leveling methods do not require quick disassembly and assembly by the staff, making it inconvenient for staff to carry and transport the entire instrument (instrument body and supporting bracket), and also inconvenient for staff to use. Utility Model Content

[0004] The purpose of this invention is to provide a soil settlement detection device for bridge and tunnel construction, so as to solve the problems mentioned in the background art.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] This utility model provides a technical solution:

[0025] Example 1

[0026] Combination Figures 1 to 4 A soil settlement detection device for bridge and tunnel construction includes a support 3, a placement platform 31 fixedly connected to the top of the support 3, a level 4 above the placement platform 31, a drive mechanism 1 inside the support 3, and an installation mechanism 2 inside the top of the support 3.

[0027] The drive mechanism 1 includes a drive assembly 11, a transmission assembly 12, and an adjustment assembly 13. The drive assembly 11 is disposed within the support 3, the transmission assembly 12 is disposed on the outer ring of the drive assembly 11, and the adjustment assembly 13 is disposed on the outer ring of the transmission assembly 12.

[0028] Drive assembly 11 includes a drive motor 1101, which is fixedly connected to the support 3. A rotating shaft 1102 is fixedly connected to the top of the drive motor 1101. A positioning cylinder 1103 is rotatably connected to the top of the outer ring of the rotating shaft 1102. The positioning cylinder 1103 is fixedly connected to the top of the placement platform 31. Transmission assembly 12 includes a bevel gear 1201, which is fixedly connected to the outer ring of the rotating shaft 1102. A support ball bearing 1202 is rotatably connected to the bottom of the bevel gear 1201. 1202 is rotatably connected to the bottom of the placement platform 31. The adjustment component 13 includes a second bevel gear 1301, which meshes with the top of the outer ring of the first bevel gear 1201. A threaded shaft 1302 is fixedly connected to the inner ring of the second bevel gear 1301. The threaded shaft 1302 is rotatably connected to the inner side of the placement platform 31. A support cylinder 1303 is rotatably connected to the inner end of the threaded shaft 1302. A fixing block 1304 is fixedly connected to the top of the support cylinder 1303. The fixing block 1304 is fixedly connected to the top of the placement platform 31.

[0029] Furthermore, the operator only needs to start the drive motor 1101 to drive the multiple threaded shafts 1302 to rotate synchronously and complete the fixation of the level instrument 4. The operation is simple and convenient for the operator to use. At the same time, the support ball 1202 is set at the bottom of the bevel gear 1201 to support the rotating bevel gear 1201, which increases the stability of the bevel gear 1201 during the rotation process and improves the transmission stability between the bevel gear 1201 and the bevel gear 2 1301.

[0030] Example 2

[0031] See Figures 1 to 4 Furthermore, based on Embodiment 1, the installation mechanism 2 includes a moving component 21 and a fixing component 22. The moving component 21 is disposed on the outer ring of the adjusting component 13, and the fixing component 22 is disposed above the placement platform 31.

[0032] The movable component 21 includes a threaded cylinder 2101, which is threadedly connected to the outer ring of the threaded shaft 1302. Movable slide rods 2102 are fixedly connected to the upper and lower sides of the threaded cylinder 2101. The movable slide rods 2102 are slidably connected to the placement platform 31. Limiting slide plates 2103 are fixedly connected to the outer side of the movable slide rods 2102. The limiting slide plates 2103 are slidably connected to the upper and lower sides of the placement platform 31. The fixed component 22 includes a clamping rod 2201, which is fixedly connected to the top of the upper limiting slide plate 2103. A base 2202 is provided on the inner side of the clamping rod 2201. The base 2202 is fixedly connected to the bottom of the level instrument 4. A positioning block 2203 is snapped into the bottom of the base 2202. The positioning block 2203 is fixedly connected to the top of the placement platform 31.

[0033] Furthermore: During the rotation of the threaded shaft 1302, the movable slide bar 2102 and the limiting slide 2103 cooperate to limit the threaded cylinder 2101, so that the threaded cylinder 2101 can move in both directions inward and outward as the threaded shaft 1302 rotates, and the limiting slide 2103 moves inward and engages with the outer side of the base 2202 to complete the fixation of the level 4.

[0034] In actual operation, when this device is used and the level instrument 4 needs to be installed, the operator first places the level instrument 4 on the platform 31. By fitting the level instrument 4, the base 2202 and the positioning block 2203 are aligned. Then, the level instrument 4 is moved downwards so that the bottom of the base 2202 contacts the top of the platform 31, and the positioning block 2203 is engaged in the bottom of the base 2202. Then, the operator starts the drive motor 1101. The drive motor 1101 drives the first bevel gear 1201 to rotate through the rotating shaft 1102. The rotation of the first bevel gear 1201 drives the threaded shaft 1302 to rotate through the second bevel gear 1301. The rotation of the multiple threaded shafts 1302 drives the multiple threaded cylinders 2101 to move inwards synchronously. The inward movement of the threaded cylinders 2101 drives the clamping rod 2201 to move inwards. The clamping rod 2201 moves inwards and engages with the outer side of the base 2202. At this time, the fixed installation of the level instrument 4 is completed.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
