Description

Technical Field

[0001] This utility model relates to the field of settlement monitoring technology, and in particular to a benchmark structure for monitoring surface settlement around foundation pits. Background Technology

[0002] During the construction of foundation pit projects, monitoring the surrounding ground settlement is a crucial step in ensuring project safety and preventing deformation and damage to surrounding buildings and structures. Monitoring markers, as the core carriers for directly acquiring settlement data, directly impact monitoring efficiency and data accuracy due to their structural rationality and ease of use. In practical engineering applications, monitoring markers need to be flexibly deployed according to the depth of the foundation pit, the monitoring range, and the site topography. They also need stable installation performance and convenient assembly / disassembly characteristics to adapt to different monitoring scenarios and reduce transportation and maintenance costs. While the markers are assembled using screws and threaded grooves, this threaded assembly method makes installation and disassembly cumbersome and prevents the rapid assembly of multiple markers. Utility Model Content

[0003] The main purpose of this utility model is to provide a benchmark structure for monitoring surface settlement around foundation pits, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A marker structure for monitoring surface settlement around a foundation pit includes an insert rod and a splicing rod. A connecting sleeve is fixedly fitted on the surface of the insert rod and at its upper end. A splicing rod is installed at the upper end of the insert rod. Extrusion blocks are movably embedded in the upper two sides of the connecting sleeve.

[0005] More preferably, the splicing rod has a limiting groove formed on both sides of its lower longitudinal surface, an embedding groove formed inside the splicing rod behind the limiting groove, and a positioning groove formed above the embedding groove.

[0006] More preferably, the connecting sleeve has push-pull openings on both sides and near the top, and the push-pull openings have rod grooves on both sides of the inside surface. A guide rod is fixedly installed inside the rod groove, and a spring is sleeved on the guide rod.

[0007] More preferably, the extrusion block is embedded in the push-pull opening, the rear end of the extrusion block passes through the limiting groove and is embedded in the embedding groove, the rear surface of the extrusion block is fixedly installed with an embedding block, the front surface of the embedding block and the upper part are fixedly installed with a positioning block, and the two side surfaces of the extrusion block are fixedly installed with sleeve blocks.

[0008] More preferably, the embedding block is embedded in the embedding groove, the positioning block is embedded in the positioning groove, the sleeve block is sleeved on the guide rod, and the lower end of the splicing rod is embedded in the connecting sleeve.

[0009] Compared with the prior art, this utility model proposes a benchmark structure for monitoring surface settlement around foundation pits, which has the following beneficial effects: In this invention, by setting up a splicing rod, a connecting sleeve, and a pressing block to cooperate with each other, when assembling the splicing rod with the insert rod, the pressing block is pressed into the push-pull opening to the maximum extent, and then the lower end of the splicing rod is inserted into the connecting sleeve, so that the pressing block is aligned with the limiting groove and the embedding block is aligned with the embedding groove. Finally, the external force pressing the pressing block is released, and at this time the spring will cause the pressing block to continuously extend out of the push-pull opening until the positioning block of the pressing block is embedded in the positioning groove of the splicing rod. In this way, the splicing rod and the insert rod can be conveniently assembled and positioned. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1-5 As shown, the marker structure for monitoring surface settlement around the foundation pit includes a pole 1 and a splicing pole 2. A connecting sleeve 3 is fixedly sleeved on the surface of the pole 1 and at the upper end. The splicing pole 2 is installed at the upper end of the pole 1. Extrusion blocks 4 are movably embedded in the upper two sides of the connecting sleeve 3.

[0016] In a preferred embodiment: a limiting groove 201 is formed on both sides of the splicing rod 2 in the lower longitudinal direction, an embedding groove 202 is formed inside the splicing rod 2 behind the limiting groove 201, and a positioning groove 203 is formed inside the embedding groove 202 at the top.

[0017] In a preferred embodiment: a push-pull opening 301 is provided on both sides and near the top of the inner side of the connecting sleeve 3. A rod groove 302 is provided on both sides of the inner side of the push-pull opening 301. A guide rod 303 is fixedly installed inside the rod groove 302. A spring 304 is sleeved on the guide rod 303.

[0018] In the above structure, the spring 304 is in an extended state in its natural state, and the elastic coefficient of the spring 304 must ensure that the pressing block 4 will not cause the positioning block 403 to exit from the positioning groove 203 without the action of a certain pressing external force, thus ensuring the stability when the splicing rod 2 and the insertion rod 1 are connected by the pressing block 4.

[0019] In a preferred embodiment: the extrusion block 4 is embedded in the push-pull opening 301, the rear end of the extrusion block 4 passes through the limiting groove 201 and is embedded in the embedding groove 202, the rear surface of the extrusion block 4 is fixedly installed with the embedding block 402, the front surface of the embedding block 402 and the upper part are fixedly installed with the positioning block 403, and the two side surfaces of the extrusion block 4 are fixedly installed with the sleeve block 401.

[0020] In a preferred embodiment: the embedding block 402 is embedded in the embedding groove 202, the positioning block 403 is embedded in the positioning groove 203, the sleeve block 401 is sleeved on the guide rod 303, and the lower end of the splicing rod 2 is embedded in the connecting sleeve 3.

[0021] In use, when assembling the splicing rod 2 with the insert rod 1, the pressing block 4 is pressed into the push-pull opening 301 to its maximum extent. Then, the lower end of the splicing rod 2 is inserted into the connecting sleeve 3, aligning the pressing block 4 with the limiting groove 201 and the embedding block 402 with the embedding groove 202. Finally, the external force pressing the pressing block 4 is released. At this time, the spring 304 will cause the pressing block 4 to continuously extend out of the push-pull opening 301 until the positioning block 403 of the pressing block 4 is embedded in the positioning groove 203 of the splicing rod 2. This allows the splicing rod 2 and the insert rod 1 to be easily assembled. When positioning and disassembling splicing rod 2 and insert rod 1, press the squeezing block 4 again to make the positioning block 403 exit from the positioning groove 203. Then pull up splicing rod 2 to complete the disassembly. When conducting settlement monitoring, the change in the height difference between the fixed benchmark point and the monitoring point marker reflects the vertical displacement of the ground surface. The marker serves as the carrier of the monitoring point and is vertically fixed at the ground surface position to be monitored around the foundation pit. The rod has precise scales or markings that are compatible with measuring equipment. The height difference between the benchmark point and the monitoring point marker is measured regularly using instruments such as a level and a total station, and the measurement data at different times are compared.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
