Description

Technical Field

[0001] The utility model relates to the technical field of line settlement detection, and specifically to a device for line settlement detection. Background Art

[0002] Settlement monitoring is a technology for detecting the settlement changes of surface or underground structures. Its principle is to use measuring equipment to periodically measure the monitoring points and record the data in order to detect and analyze the trends and laws of settlement changes. Settlement refers to the sinking or falling phenomenon of surface or underground structures due to various reasons. In urban construction and large-scale infrastructure construction, settlement monitoring is very important, which can effectively predict and control the safety of buildings, the stability of equipment, the normal operation of pipelines, etc.

[0003] After searching, the announcement number CN218481080U discloses a ground settlement monitoring device for subway construction lines, including a buried pipe, the outer sleeve of the buried pipe is provided with a settlement pipe, the buried pipe is connected with an anchor rod in axial sliding and circumferential rotation, the bottom of the buried pipe is provided with a through hole and the top is provided with an operation hole, and the bottom of the buried pipe is also connected with a protective guide sleeve provided at the bottom of the settlement pipe. In this utility model, an anchor rod is provided in the buried pipe, and the anchor rod and the buried pipe are connected by a connection method of circumferential rotation and axial sliding. The top of the buried pipe is provided with an operation hole, and the bottom is provided with a through hole. When the buried pipe is placed at the bottom of the anchor pit, the buried pipe is fixed when the control anchor rod is inserted into the bottom of the anchor pit, and there is no need to pour concrete at the bottom of the anchor pit and connect embedded parts, which greatly reduces the difficulty of installing the detection device.

[0004] The above-mentioned subway construction line surface settlement monitoring device is provided with a settlement pipe on the outside of the buried pipe, and the settlement pipe changes with the geological settlement, so that the monitoring personnel can understand the current line settlement changes. In this design, a guide sleeve is provided at the connection between the settlement pipe and the buried pipe. Therefore, this design easily leads to that when the settlement pipe changes with the settlement of the terrain, the settlement pipe will synchronously affect the buried pipe through the protective guide sleeve, so that the originally relatively static buried pipe will settle synchronously with the terrain, which will cause errors in settlement monitoring. Utility Model Content

[0006] The technical solution of the utility model is as follows: a line settlement detection device, including an inner sleeve component, the inner sleeve component includes an inner sleeve, an anchoring mechanism is installed inside the inner sleeve, the inner sleeve component also includes a slide bar, the slide bar is fixedly connected to three groups of vertical grooves opened in a ring shape on the outer side of the inner sleeve, an outer sleeve component is arranged on the outer side of the inner sleeve, the outer sleeve component includes an outer sleeve, and the outer sleeve is arranged on the outer side of the inner sleeve.

[0007] Preferably, the inner sleeve assembly further comprises top columns, which are in three groups and are annularly fixedly connected to the tops of the three groups of vertical slots on the outer side of the inner sleeve.

[0008] Preferably, the bottom of the top column is fixedly connected to the top of the sliding rod.

[0009] Preferably, the outer sleeve assembly further comprises a sliding sleeve, and the sliding sleeve is slidably connected to the outer side of the sliding rod.

[0010] Preferably, the inner sleeve assembly further comprises a spring ring, which is sleeved on the outside of the slide rod, one end of the spring ring is elastically connected to the bottom of the top column, and the other end of the spring ring is elastically connected to the slide sleeve.

[0023] See also Figure 1 and Figure 2 The utility model provides a technical solution: a device for detecting line settlement, comprising an inner sleeve component 1, the inner sleeve component 1 comprising an inner sleeve 11, an anchor mechanism 3 being installed inside the inner sleeve 11, the inner sleeve component 1 also comprising a slide bar 13, the slide bar 13 being fixedly connected to three groups of vertical grooves opened in a ring shape on the outer side of the inner sleeve 11, an outer sleeve component 2 being arranged on the outer side of the inner sleeve component 1, the outer sleeve component 2 comprising an outer sleeve 21, the outer sleeve 21 being arranged on the outer side of the inner sleeve 11, and the problem that the prior art easily leads to the settlement pipe affecting the buried pipe synchronously through the protective guide sleeve when the settlement pipe settles with the terrain, thereby causing the originally relatively stationary buried pipe to settle synchronously with the terrain, thereby causing errors in settlement monitoring.

[0024] See also Figure 3The inner sleeve assembly 1 also includes a top column 12, which is composed of three groups and is fixedly connected to the top of the three groups of vertical slots on the outside of the inner sleeve 11 in a ring shape. The bottom of the top column 12 is fixedly connected to the top of the sliding rod 13. The outer sleeve assembly 2 also includes a sliding sleeve 24, which is slidably connected to the outside of the sliding rod 13. The inner sleeve assembly 1 also includes a spring ring 131, which is sleeved on the outside of the sliding rod 13. One end of the spring ring 131 is elastically connected to the bottom of the top column 12, and the other end of the spring ring 131 is elastically connected to the sliding sleeve 24. The initial position of the sliding sleeve 24 can be set by the spring ring 131 to prevent the sliding sleeve 24 from sliding downward due to gravity when the entire device is installed in the anchor pit.

[0025] See also Figure 4 The outer sleeve assembly 2 also includes a slide seat 23, which is fixedly connected to the outside of the slide sleeve 24. The slide seat 23 is fixedly connected to the outer sleeve 21. The outer sleeve assembly 2 also includes a side plate 22, which is located on the outside of the outer sleeve 21 and is fixedly connected to the slide seat 23. The side plate 22 is annularly provided with an injection groove 221 throughout the body. Through this design, when concrete is poured between the side plate 22 and the anchor pit, the contact area between the side plate 22 and the concrete is increased.

[0026] The working principle and use process of the utility model are as follows:

[0027] First, an anchor pit is dug at the location to be tested, and then the entire device is placed in the anchor pit, and concrete is poured on the inner wall of the anchor pit and the side plate 22 to complete the fixing of the outer sleeve 21 and the anchor pit, and then the anchoring mechanism 3 is rammed into the soil below the inner sleeve 11 using a tamping tool to complete the fixing of the inner sleeve 11. In particular, when the outer sleeve 21 is vertically displaced due to the influence of terrain settlement, the outer sleeve 21 will slide vertically on the outside of the slide rod 13 through the slide seat 23 and the slide sleeve 24, and because the slide rod 13 is located on the outside of the inner sleeve 11 that has been fixed, when the outer sleeve 21 settles with the terrain and slides on the outside of the inner sleeve 11, it will not affect the inner sleeve 11. This design can effectively reduce the influence of terrain settlement on the inner sleeve 11 and thus reduce the detection error.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
