Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a building ground subsidence monitoring device. Background Art

[0002] Ground subsidence, also known as ground subsidence or ground collapse, is a local downward movement caused by the consolidation and compression of loose underground strata, which leads to a lowering of the surface elevation of the earth's crust. It generally manifests itself in two forms: regional subsidence and local subsidence. It can cause buildings to tilt and destroy the stability of the foundation.

[0003] During the construction process, it is necessary to monitor the ground settlement in the construction area, so as to use the actual settlement as a basis for controlling the construction progress, determining the time for unloading and evaluating the effect of foundation treatment. The commonly used method is the magnetic ring settlement meter method. During monitoring, the soft ruler settlement meter is inserted into the settlement tube to detect the height of the settlement magnetic ring to obtain the settlement of the settlement magnetic ring. During the operation, it is necessary to measure multiple settlement magnetic rings on multiple settlement tubes at regular intervals, and the monitoring efficiency is low.

The detection assembly includes a connecting piece and a detection piece. The settlement ring is connected to the settlement pipe through the connecting piece. When the settlement ring moves relative to the settlement pipe along the first direction, it can drive the connecting piece to move. The detection 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-mentioned ground settlement monitoring device. Through the above-mentioned arrangement, the ground settlement amount can be automatically and accurately measured without manual operation, thereby improving the monitoring efficiency.

[0005] However, in this application, the detection range of the sedimentation ring is limited by the length of the connecting piece, and when the connecting piece slides relative to the sedimentation tube, mud is easily entered into its moving channel, which will affect the sensitivity of the movement of the sedimentation ring, and its use has certain shortcomings.

[0022] See also Figure 1-7 The present embodiment discloses a building ground settlement monitoring device, including a settlement pipe 10, a monitoring ring 20 and a detection assembly 30. The settlement pipe 10 is inserted into a hole in the building ground, and a guide channel 11 extending along the sinking direction is provided in the settlement pipe 10; the monitoring ring 20 is sleeved on the outside of the settlement pipe 10 and moves downward with the settlement of the building ground; the detection assembly 30 is arranged in the guide channel 11, and the height position of the detection assembly 30 is synchronously raised and lowered with the height position of the monitoring ring 20, so as to detect the sinking distance of the monitoring ring 20.

[0023] Compared with the prior art, the building ground settlement monitoring device of this solution is configured to synchronously rise and fall the detection assembly 30 and the monitoring ring 20, and detect the sinking distance of the monitoring ring 20 during the rising and falling process of the detection assembly 30, without manual measurement, and has high monitoring efficiency. In addition, the detection assembly 30 is arranged in the internal guide channel 11 of the settlement pipe 10, which can greatly reduce the impact of external soil on the monitoring environment 20 and improve the convenience of monitoring.

[0024] In this embodiment, a first magnetic component 21 is provided in the monitoring ring 20, and the detection component 30 includes a second magnetic component 31 and a detection component 32. The first magnetic component 21 and the second magnetic component 31 attract each other to achieve synchronous lifting and lowering of the height position of the detection component 30 and the monitoring ring 20, and the detection component 32 is used to detect the height change of the second magnetic component 31.

[0025] Specifically, the first magnetic member 21 is a magnet block, and the second magnetic member 31 is a metal detection ball. Of course, the first magnetic member 21 in this solution can be metal, and the second magnetic member 31 is a magnet block. It is only necessary to satisfy that the detection component 32 can detect the height change of the second magnetic member 31. For example, the second magnetic member 31 is a magnet block, and the detection component 32 is a position sensor that can detect the relative position between the second magnetic member 31 and the magnet block in real time, and the sinking distance of the monitoring ring 20 is calculated by the relative position of the two.

[0026] In this embodiment, the detection component 32 includes a controller 321, a detection wire 322 and a resistor bar 323. The detection wire 322 and the resistor bar 323 are respectively arranged in the guide channel 11. The controller 321 is electrically connected to one end of the detection wire 322 and one end of the resistor bar 323 respectively. The metal detection ball is electrically contacted with the detection wire 322 and the resistor bar 323 respectively to form a detection circuit. When the height of the metal detection ball changes, the resistance value of the resistor bar 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.

[0027] 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 the electrical devices used 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 equipment, lights, speakers and microphones; the controller 321 is an Intel processor, AMD processor, PLC controller 321, ARM processor or a single-chip microcomputer, and it also includes a motherboard, a memory stick, a storage medium and a power supply. The power supply is AC or a lithium battery; when a display screen is provided, a display card is also provided.

[0028] The metal detection ball contacts the detection wire 322 and the resistor bar 323 respectively, and forms a detection circuit by being electrically connected to the controller 321, wherein a mechanism similar to a sliding rheostat is formed between the metal detection ball and the resistor bar 323. When the position of the metal detection ball changes, the resistance value of the resistor bar 323 connected to the detection circuit is different, so that the sinking distance of the metal detection ball can be calculated based on the resistance value.

[0029] In this embodiment, the building ground settlement monitoring device also includes a limit component 40, the guide channel 11 includes two, and the two second magnetic components 31 are respectively arranged in the two guide channels 11. The two ends of the limit component 40 are respectively connected to the two second magnetic components 31 for controlling the adsorption or separation of the first magnetic component 21 and the second magnetic component 31.

[0030] It should be noted that the setting of the limit assembly 40 can limit the relative position of the two second magnetic members 31, and when the second magnetic member 31 and the first magnetic member 21 are mutually attracted, the second magnetic member 31 is prevented from moving in the guide channel 11, so as to ensure that the second magnetic member 31 can be stably associated with the detection component 32 to accurately detect the sinking distance. At the same time, the limit assembly 40 can also realize the separation of the first magnetic member 21 and the second magnetic member 31, which is convenient for the installation of the second magnetic member 31.

[0031] In this embodiment, an opening is provided on one side of the guide channel 11 close to the axial direction of the settling tube 10, and the width of the opening is smaller than the width of the second magnetic member 31. The limit assembly 40 passes through the opening and is connected to the second magnetic member 31. The detection component 32 is provided on the side of the guide channel 11 away from the axial direction of the settling tube 10. The detection wire 322 is parallel to and does not contact the resistance bar 323 and is provided on the side of the guide channel 11 away from the axial direction of the settling tube 10.

[0032] In this embodiment, the limit assembly 40 includes a limit driving member 41, a limit pull rope 42 and a limit seat 43. The two output ends of the limit driving member 41 are respectively connected to one end of two limit pull ropes 42, and the other ends of the two limit pull ropes 42 are respectively connected to the corresponding second magnetic member 31. The limit driving member 41 is fixed on the limit seat 43, and a limit rod 431 parallel to the output direction of the limit driving member 41 is provided on the limit seat 43. The limit pull rope 42 is connected to the second magnetic member 31 after passing through the limit rod 431 in an S shape.

[0033] A tension sensor is provided at the connection between the limit driving member 41 and the limit pull 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 adsorption member and the second adsorption member are mutually adsorbed, and the detection circuit is closed. The limit pull rope 42 is wound around the limit rod 431 in an S shape, which is conducive to limiting and controlling the position of the limit pull rope 42 and the second magnetic member 31.

[0034] The limit drive 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 pull rope 42 is loosened, so that the metal detection balls can contact the detection strip. When the metal detection ball contacts the detection strip, the tension sensor detects that the tension value is L2. When the metal detection ball monitors the settlement of the monitoring ring 20, the tension value always remains stable. 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 the staff is required to inspect the settlement tube 10.

[0035] In this embodiment, the two guide channels 11 are double helical channels. The spiral channel ensures stable movement between the second magnetic component 31 and the first magnetic component 21, and prevents the second magnetic component 31 from falling directly due to gravity. Of course, the guide channel 11 can also be set as an inclined or other shaped channel, as long as the stable and synchronous movement between the first magnetic component 21 and the second magnetic component 31 can be guaranteed. The sedimentation tube 10 is non-ferrous, and the metal detection ball is iron, and the diameter of the metal detection ball is smaller than the width of the guide channel 11.

[0036] The guide channel 11 is spirally arranged along the length direction of the sedimentation tube 10, and the two guide channels 11 are arranged in a double helix structure. The inner walls of the guide channels 11 are respectively provided with a detection wire 322 and a resistor bar 323. The metal detection ball contacts the detection wire 322 and the resistor bar 323 respectively under the action of the magnetic suction block. When the metal detection ball contacts the two detection wires 322 and the resistor bar 323, a detection loop is formed.

[0037] The two metal detection balls are tightened under the action of the limit assembly 40 and suspended on the upper part of the two guide channels 11. When the monitoring ring 20 is installed in place, the magnetic block attracts the metal detection balls, so that the limit assembly 40 is stretched, and the metal detection balls contact the detection component 32.

[0038] According to different actual monitoring depths, multiple sections of guide channels 11 may be arranged inside the settling tube 10 , and corresponding monitoring rings 20 may be arranged outside the settling tube 10 .

[0039] In this embodiment, the building ground settlement monitoring device further includes an auxiliary detection belt 50, which is arranged on the outer wall of the monitoring ring 20 and is used to support the channel of the settlement pipe 10 in the building ground. The outer end of the auxiliary detection belt 50 is inclined in the direction away from the settlement pipe 10, and the auxiliary detection belt 50 can be inclined upward or downward, and the number of the auxiliary detection belts 50 inclined upward is the same as the number of the auxiliary detection belts 50 inclined downward. The auxiliary detection belt 50 is used to get stuck in the soil to increase the friction with the soil, and the auxiliary detection belt 50 is elastic, which can ensure the sinking stability of the monitoring ring 20.

[0040] Directions: When the device is used, the settling tube 10 is first placed in the ground channel, the limiting assembly 40 is tightened, and the limiting pull rope 42 is twisted by the limiting rod 431 to squeeze the two metal detection balls and the opening of the guide channel 11 tightly to avoid displacement between the metal detection balls and the guide channel 11; The monitoring ring 20 is sleeved on the outside of the settling tube 10. Under the action of the magnetic block, the metal detection ball is pulled to move toward the detection bar. The limit motor is operated to loosen the limit pull rope 42, so that the metal detection ball contacts the detection bar. At this time, the tension sensor detects a tension value of L2, so that the two metal detection balls are connected to the resistor bar 323 and the detection wire 322 to form a detection loop. As the monitoring ring 20 sinks, the two metal detection balls move downward along the two guide channels 11 at the same time. According to the different contact positions between the metal detection balls and the resistor bar 323, different resistance values ​​correspond to different heights of the sedimentation tube 10. The sinking distance of the monitoring ring 20 can be known based on the resistance value in the detection circuit.

[0041] When the monitoring ring 20 sinks downward, the metal detection ball spirally descends along the guide channel 11, which can effectively improve the monitoring accuracy under the same sinking distance.

[0042] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
