Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to a building ground settlement monitoring device. Background Art

[0002] Ground settlement, also known as ground subsidence or land subsidence, is a local downward movement caused by the consolidation and compression of loose underground strata, resulting in a decrease in the elevation of the earth's surface. It generally manifests in two forms: regional subsidence and local subsidence, which can cause building tilt and damage the stability of the foundation.

[0003] During the construction process, it is necessary to monitor the ground settlement of the construction area to facilitate using the actual settlement amount as a basis for controlling the construction progress, determining the time of loading and unloading, and evaluating the effect of foundation treatment. The commonly used method is the magnetic ring settlement gauge method. During monitoring, a flexible ruler settlement gauge is inserted into the settlement pipe to detect the height of the settlement magnetic ring, so as to obtain the settlement situation of the settlement magnetic ring. During the operation process, it is necessary to measure multiple settlement magnetic rings on multiple settlement pipes regularly, and the monitoring efficiency is relatively low.

In this application, the settlement pipe is arranged to penetrate along the first direction, the settlement ring is slidably sleeved on the outer periphery of the settlement pipe along the first direction, the detection assembly includes a connecting piece and a detecting piece, the settlement ring is connected to the settlement pipe through the connecting piece, and when the settlement ring moves relative to the settlement pipe along the first direction, it can drive the connecting piece to move, and the detecting piece can monitor the settlement amount of the settlement ring relative to the settlement pipe by measuring the moving distance of the connecting piece. The ground settlement monitoring method uses the above ground settlement monitoring device. Through the above settings, it is possible to automatically and accurately measure the ground settlement amount without manual operation, improving the monitoring efficiency.

[0005] However, in this application, the detection range of the settlement ring is limited by the length of the connecting piece, and when the connecting piece slides relative to the settlement pipe, soil is likely to enter the moving channel, which will affect the sensitivity of the settlement ring movement, and there are certain deficiencies in use. Summary of the Invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the terms in the present invention can be understood according to specific situations.

[0034] See Figures 1-7 , this embodiment discloses a building ground settlement monitoring device, including a settlement pipe 10, a monitoring ring 20 and a detection component 30. The settlement pipe 10 is inserted into the pore passage of the building ground, and a guiding channel 11 extending along the sinking direction is arranged in the settlement pipe 10; the monitoring ring 20 is sleeved outside the settlement pipe 10 and moves downward with the settlement of the building ground; the detection component 30 is arranged in the guiding channel 11, and the height position of the detection component 30 synchronously rises and falls with the height position of the monitoring ring 20 for detecting the sinking distance of the monitoring ring 20.

[0035] Compared with the prior art, the building ground settlement monitoring device of this solution synchronously lifts and lowers the detection component 30 and the monitoring ring 20. During the lifting and lowering process of the detection component 30, the sinking distance of the monitoring ring 20 is detected, eliminating the need for manual measurement and improving the monitoring efficiency. Moreover, the detection component 30 is arranged in the internal guiding channel 11 of the settlement pipe 10, which can greatly reduce the influence of external soil, etc. on the monitoring environment and improve the convenience of monitoring.

[0036] In this embodiment, a first magnetic attracting member 21 is arranged in the monitoring ring 20. The detection component 30 includes a second magnetic attracting member 31 and a detection component 32. The first magnetic attracting member 21 and the second magnetic attracting member 31 attract each other to realize the synchronous lifting and lowering of the height positions of the detection component 30 and the monitoring ring 20. The detection component 32 is used to detect the height change of the second magnetic attracting member 31.

[0037] Specifically, the first magnetic attracting member 21 is a magnet block, and the second magnetic attracting member 31 is a metal detection ball. Of course, the first magnetic attracting member 21 in this solution can be metal, and the second magnetic attracting member 31 can be a magnet block. It only needs to satisfy that the detection component 32 can detect the height change of the second magnetic attracting member 31. For example, the second magnetic attracting member 31 is a magnet block, and the detection component 32 is a position sensor that can detect the relative position with the magnet block in real time. The sinking distance of the monitoring ring 20 is calculated through the relative position of the two.

[0038] In this embodiment, the detection component 32 includes a controller 321, a detection wire 322, and a resistance strip 323. The detection wire 322 and the resistance strip 323 are respectively arranged in the guiding channel 11. The controller 321 is electrically connected to one end of the detection wire 322 and one end of the resistance strip 323 respectively. The metal detection ball is in electrical contact with the detection wire 322 and the resistance strip 323 respectively to form a detection circuit. When the height of the metal detection ball changes, the resistance value of the resistance strip 323 connected to the detection circuit is different. The controller 321 calculates the sinking distance of the monitoring ring 20 through the resistance value of the detection circuit.

[0039] The position of the controller 321 of this solution is set by the staff according to the actual situation during operation. The controller 321 is used to control all the electrical appliances in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication devices, lights, speakers, and microphones; the controller 321 is an Intel processor, an AMD processor, a PLC controller 321, an ARM processor, or a single-chip microcomputer. The accessories used with it also include a main board, a memory module, a storage medium, and a power supply. The power supply is mains electricity or a lithium battery; when there is a display screen, a display card is also provided.

[0040] The metal detection ball is in contact with the detection wire 322 and the resistance strip 323 respectively, and forms a detection loop by being electrically connected to the controller 321. A mechanism similar to a sliding rheostat is formed between the metal detection ball and the resistance strip 323. When the position of the metal detection ball changes, the resistance value of the resistance strip 323 connected to the detection loop is different, so that the sinking distance of the metal detection ball can be calculated according to the resistance value.

[0041] In this embodiment, the building ground settlement monitoring device further includes a limiting component 40. There are two guiding channels 11, and two second magnetic attracting members 31 are respectively arranged in the two guiding channels 11. Both ends of the limiting component 40 are respectively connected to the two second magnetic attracting members 31 for controlling the adsorption or separation of the first magnetic attracting member 21 and the second magnetic attracting member 31.

[0042] It should be noted that the setting of the limiting component 40 can limit the relative positions of the two second magnetic attracting members 31. When the second magnetic attracting member 31 and the first magnetic attracting member 21 are mutually adsorbed, it can prevent the second magnetic attracting member 31 from moving in the guiding channel 11, so as to ensure that the second magnetic attracting member 31 can be stably associated with the detection component 32 to accurately detect the sinking distance. At the same time, the limiting component 40 can also realize the separation of the first magnetic attracting member 21 and the second magnetic attracting member 31, which is convenient for the installation of the second magnetic attracting member 31.

[0043] In this embodiment, an opening is provided on one side of the guiding channel 11 close to the axial center direction of the settlement pipe 10. The width of the opening is smaller than the width of the second magnetic attracting member 31. The limiting component 40 passes through the opening and is connected to the second magnetic attracting member 31. The detection component 32 is arranged on the side of the guiding channel 11 away from the axial center direction of the settlement pipe 10. The detection wire 322 and the resistance strip 323 are arranged in parallel and not in contact on the side of the guiding channel 11 away from the axial center direction of the settlement pipe 10.

[0044] In this embodiment, the limiting component 40 includes a limiting driving member 41, a limiting pulling rope 42 and a limiting seat 43. Two output ends of the limiting driving member 41 are respectively connected to one ends of two limiting pulling ropes 42. The other ends of the two limiting pulling ropes 42 are respectively connected to the corresponding second magnetic attracting members 31. The limiting driving member 41 is fixed on the limiting seat 43. A limiting rod 431 parallel to the output direction of the limiting driving member 41 is provided on the limiting seat 43. The limiting pulling rope 42 is wound around the limiting rod 431 in an S shape and then connected to the second magnetic attracting member 31.

[0045] A tension sensor is provided at the connection between the limit driving member 41 and the limit pulling rope 42. When the tension sensed by the tension sensor is greater than or equal to the first tension value, the first magnetic member 21 and the second magnetic member 31 are separated. When the tension sensed by the tension sensor is less than the first tension value, the first magnetic attachment member and the second magnetic attachment member adsorb each other, and the detection circuit is closed. The limit pulling rope 42 is wound around the limit rod 431 in an S shape, which is beneficial to limit and control the position of the limit pulling rope 42 and the second magnetic member 31.

[0046] The limit driving member 41 is a limit motor. In the initial state, the two metal detection balls are separated from the detection strip, and the detection value of the tension sensor is L1. When the tension sensor detects that the tension value is greater than L1, the limit motor rotates to move the positions of the two limit rods 431, and the limit pulling rope 42 is loosened, so that the metal detection balls can contact the detection strip. When the metal detection balls contact the detection strip, the tension sensor detects that the tension value is L2. When the metal detection balls monitor the settlement of the monitoring ring 20, the tension value remains stable all the time. When the tension value suddenly decreases, it indicates that at least one of the metal detection balls may be separated from the monitoring ring 20, and then the staff needs to repair the settlement pipe 10.

[0047] In this embodiment, the two guiding channels 11 are double spiral channels. The spiral channels ensure the stable movement between the second magnetic member 31 and the first magnetic member 21, and prevent the second magnetic member 31 from falling directly due to gravity. Of course, the guiding channels 11 can also be set as inclined or other shaped channels, as long as the stable synchronous movement between the first magnetic member 21 and the second magnetic member 31 can be ensured. The settlement pipe 10 is non-ferrous, the metal detection balls are ferrous, and the diameter of the metal detection balls is smaller than the width of the guiding channels 11.

[0048] The guiding channels 11 are spirally arranged along the length direction of the settlement pipe 10, and the two guiding channels 11 are arranged in a double spiral structure. The inner walls of the guiding channels 11 are respectively provided with detection wires 322 and resistance strips 323. The metal detection balls contact the detection wires 322 and the resistance strips 323 respectively under the action of the magnetic attraction blocks. When the metal detection balls contact the two detection wires 322 and the resistance strips 323, a detection circuit is formed.

[0049] The two metal detection balls are tightened under the action of the limit assembly 40 and hover above the two guiding channels 11. After the monitoring ring 20 is installed in place, the magnetic attraction blocks attract the metal detection balls, stretching the limit assembly 40, and the metal detection balls contact the detection component 32.

[0050] According to different actual monitoring depths, multiple guiding channels 11 can be arranged inside the settlement pipe 10, and corresponding monitoring rings 20 can be arranged outside the settlement pipe 10.

[0051] In this embodiment, the building ground settlement monitoring device further includes an auxiliary detection belt 50. The auxiliary detection belt 50 is arranged on the outer wall of the monitoring ring 20 and is used to support the settlement pipe 10 in the pore passage of the building ground. The outer end of the auxiliary detection belt 50 inclines away from the settlement pipe 10. The auxiliary detection belt 50 can incline upward or downward, and the number of the upward-inclined auxiliary detection belts 50 is the same as that of the downward-inclined auxiliary detection belts 50. The auxiliary detection belt 50 is used to be stuck in the soil to increase the friction with the soil, and the auxiliary detection belt 50 has elasticity to ensure the sinking stability of the monitoring ring 20.

[0052] Usage method:

[0053] When the device is specifically used, first, the settlement pipe 10 is arranged in the ground pore passage, and the limiting assembly 40 is tightened. Under the torsional action of the limiting rod 431, the limiting pull rope 42 makes the two metal detection balls tightly squeeze at the opening of the guiding channel 11 to prevent displacement between the metal detection balls and the guiding channel 11.

[0054] The monitoring ring 20 is sleeved outside the settlement pipe 10. Under the action of the magnetic attraction block, the metal detection balls are pulled to move towards the detection strip. The limiting motor runs to loosen the limiting pull rope 42, so that the metal detection balls contact the detection strip. At this time, the tension sensor detects that the tension value is L2, and a detection circuit is formed by connecting the two metal detection balls with the resistance strip 323 and the detection wire 322.

[0055] As the monitoring ring 20 sinks, the two metal detection balls simultaneously move downward along the two guiding channels 11. According to the different contact positions of the metal detection balls with the resistance strip 323, different resistance values correspond to different heights of the settlement pipe 10. The sinking distance of the monitoring ring 20 can be known according to the resistance value in the detection circuit.

[0056] When the monitoring ring 20 sinks downward, the metal detection balls spiral downward along the guiding channels 11, and the monitoring accuracy can be effectively improved under the same sinking distance.

[0057] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
