Description

Technical Field

[0001] The utility model relates to a monitoring device, in particular to a foundation settlement monitoring device, belonging to the technical field of foundation settlement monitoring. Background Art

[0002] The foundation refers to the soil or rock mass supporting the foundation under the building. The soil layer used as the building foundation is divided into rock, crushed stone soil, sand, silt, clay and artificial fill. There are two types of foundations: natural foundation and artificial foundation (composite foundation). The natural foundation is a natural soil layer that does not require human reinforcement, while the artificial foundation needs human reinforcement. Common ones include stone chip cushion, sand cushion, mixed ash soil backfill and compaction, etc. Foundation settlement refers to the sinking of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, will cause the building to tilt and crack, so that it cannot be used normally. The existing foundation settlement prediction method is limited by the fact that its assumptions are not consistent with the actual conditions. The settlement prediction results are often quite different from the measured settlement values. The research on foundation settlement prediction methods needs further development.

[0003] A Chinese patent publication (CN202223515754.X) discloses a foundation settlement monitoring device, which monitors soil settlement through a displacement monitoring unit. Since a plurality of displacement monitoring units are arranged on the settlement rod, and the plurality of displacement monitoring units are located in different directions, when the foundation settles in different directions, the displacement monitoring units in each direction monitor different settlement amounts, thereby determining whether uneven settlement of the foundation occurs. However, when the application is used, since the settlement block only moves vertically, when the local foundation settles, the settlement block is easily broken, which affects the normal use of the monitoring device;

[0004] In order to solve the above technical problems, a foundation settlement monitoring device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides a foundation settlement monitoring device, which is composed of a positioning mechanism 10 and a monitoring mechanism 20.

[0027] The positioning mechanism 10 includes a positioning tube 11, a fixed plate 14 and a protective sleeve 18. A mounting frame 25 is fixedly connected to one side of the interior of the positioning tube 11 for mounting and connecting the monitoring mechanism 20 with the positioning tube 11. A straightening ring 13 is fixedly connected to one side of the fixed plate 14. The straightening ring 13 is mounted on one side of the positioning tube 11. One side of the fixed plate 14 is provided with fixing holes 16 equidistantly distributed for connecting the fixed plate 14 to the ground through a fixing cone and other components. The straightening ring 13 straightens the positioning tube 11 to prevent the positioning tube 11 from being misaligned during installation. The protective sleeve 18 is mounted at the connection between the positioning tube 11 and the straightening ring 13. A groove 17 is integrally formed on one side of the fixed plate 14. The protective sleeve 18 is engaged with the fixed plate 14 through the groove 17. A sealing ring 19 is fixedly connected to one side of the protective sleeve 18 for sealing and protecting the connection between the positioning tube 11 and the straightening ring 13 to prevent the connection from rusting and making it difficult to disassemble the positioning tube 11 and the straightening ring 13.

[0028] In one embodiment, in order to facilitate the adjustment of the penetration depth of the positioning tube 11 according to needs, screw holes 12 are evenly distributed on one side of the positioning tube 11, and bolts 15 are evenly distributed on one side of the straightening ring 13 and threadedly connected. One end of the bolt 15 is threadedly connected to the positioning tube 11 through the screw hole 12.

[0029] The monitoring mechanism 20 includes a settlement block 21, a connecting rope 23 and a tension sensor 24. The tension sensor 24 is evenly distributed and installed on one side of the mounting frame 25. The settlement blocks 21 are evenly distributed and arranged on one side of the positioning tube 11. A plurality of settlement blocks 21 located at different depths are arranged to facilitate monitoring of the settlement state of the foundation at different depths. A GPS locator 22 is installed on one side of the interior of the settlement block 21. The GPS locator 22 records the trajectory of the settlement block 21 moving with the foundation settlement, which is convenient for calculating the foundation settlement model and improving the accuracy of the monitoring results. One end of the connecting rope 23 is fixedly connected to the settlement block 21, and one side of the connecting rope 23 passes through the positioning tube 11. The connecting rope 23 is fixedly connected to the settlement block 21. One side of the connecting rope 23 passing through the positioning cylinder 11 is covered with a rubber sleeve 26, and the rubber sleeve 26 is fixedly connected to the positioning cylinder 11, and the rubber sleeve 26 prevents the contact surface of the connecting rope 23 and the positioning cylinder 11 from being worn. One end of the connecting rope 23 passing through the positioning cylinder 11 is fixedly connected to the tension transmission part of the tension sensor 24. When the sinker 21 moves, the tension sensor 24 is pulled by the connecting rope 23, and the moving distance of the sinker 21 is judged by the force exerted on the tension sensor 24. In order to facilitate the limitation of the initial position of the sinker 21 during pre-embedding, the two sides of the sinker 21 are symmetrically fixedly connected with limit rods 27 to prevent the position of the sinker 21 from shifting during pre-embedding and affecting the monitoring result.

[0030] In one embodiment, the connecting rope 23 is composed of a rope core 233, a nylon braided layer 232 and an anti-corrosion layer 231. The nylon braided layer 232 is sleeved on one side of the rope core 233, and the anti-corrosion layer 231 is fixedly connected to one side of the nylon braided layer 232. The anti-corrosion ability of the connecting rope 23 is enhanced by the anti-corrosion layer 231, and the service life of the connecting rope 23 is extended. The nylon braided layer 232 ensures the structural strength of the connecting rope 23 and prevents the connecting rope 23 from breaking.

[0031] When the utility model is in operation: the monitoring device is pre-buried at a designated position, the fixing plate 14 is fitted with the ground, the positioning tube 11 is vertically moved to adjust the pre-buried depth of the positioning tube 11, and after adjustment, the bolt 15 is screwed into the straightening ring 13, so that one end of the bolt 15 is connected to the positioning tube 11 through the screw hole 12, and the penetration depth of the positioning tube 11 is fixed, and the fixing plate 14 is fixed to the ground through the fixing cone and other components in conjunction with the fixing hole 16, and the protective sleeve 18 is sleeved at the connection between the straightening ring 13 and the positioning tube 11, so that the sealing ring 19 is fitted with the positioning tube 11, and at the same time, one side of the protective sleeve 18 is stuck in the groove 17, and the foundation settlement drives the settlement block 21 to move, so that the settlement block 21 pulls the tension sensor 24 through the connecting rope 23, and cooperates with the GPS locator 22 to record the movement trajectory of the settlement block 21, so as to make a foundation settlement model, so as to obtain more accurate monitoring results.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
