Description

[0001] The invention belongs to the technical field of building settlement detection, and in particular relates to a building settlement detection reference device. Background Art

[0002] In the field of modern construction, the stability of buildings is related to the safety of people's lives and property. With the acceleration of urbanization, a large number of high-rise buildings, bridges and other infrastructure are constantly emerging, and the demand for building settlement monitoring is becoming increasingly urgent.

[0003] Accurate settlement detection can timely discover potential safety hazards of buildings and provide key data for the stability assessment of building structures. Traditional settlement detection methods have many limitations. For example, when using a level to observe settlement, its accuracy is easily affected by factors such as the observation environment and human operation. In complex terrain or severe weather conditions, the measurement error will increase significantly, resulting in inaccurate detection results. At the same time, the settlement of buildings is a long-term process, and the existing level can only collect single measurement data. If long-term data is required, the inspection personnel need to perform multiple measurements at different time points, which is more troublesome. In addition, during each measurement of the level, the measurement data is easily affected by environmental factors, such as temperature changes, humidity, etc., which causes the measurement benchmark to shift, affecting the continuity and reliability of the monitoring data.

[0004] Therefore, a building settlement detection benchmark device with high precision, easy installation, adaptability to long-term monitoring and wide versatility is developed to effectively improve the accuracy and efficiency of building settlement detection and ensure the safety and stability of construction projects.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1 - Figure 6 As shown, a building settlement detection benchmark device comprises:

[0031] The collection unit is arranged at the building settlement observation point and is used to record the building settlement data, including a first installation shell 1 connected to the building and a plurality of collection hydraulic tanks 2 connected to the inside of the first installation shell 1, wherein the inside of the collection hydraulic tank 2 is connected to a first pressure sensor 4 for detecting hydraulic pressure, and the collection hydraulic tank 2 is connected to a first connecting pipe 3, and a connecting pipe 8 is connected between the first connecting pipes 3 on adjacent collection hydraulic tanks 2;

[0032] The control part is arranged in a stable area away from the building settlement area, and is used to transport the detection liquid to the collection part, and calculate the building settlement data according to the hydraulic pressure data of the detection liquid, including a lifting component arranged on the ground of the stable area and a second mounting shell 15 arranged on the lifting component, the second mounting shell 15 is connected to a liquid storage tank 16 for storing the detection liquid, the liquid storage tank 16 is connected to a second connecting pipe 17, the second connecting pipe 17 and the first connecting pipe 3 are connected to a first liquid guide tube 9 and a second liquid guide tube 10, and the liquid storage tank 16 is connected to a second pressure sensor 22;

[0033] A circulation component, arranged on the liquid storage tank 16 and used for circulating the detection liquid in the collection hydraulic tank 2 and the liquid storage tank 16;

[0034] The control center 26 is connected to the bottom of the second installation shell 15, and is used to record the hydraulic data of the detection liquid in the collection part and the control part, and calculate the building settlement data according to the hydraulic data.

[0035] As can be seen from the above, a set of building settlement detection reference device is formed by setting up a collection part, a control part, a circulation component and a control center 26. The collection part is set at the building settlement observation point, and the control part is set outside the building settlement area. The detection liquid is circulated between the control group and the collection part. Due to the height difference between the control group and the collection part, the first pressure sensor 4 and the second pressure sensor 22 respectively detect the pressure values ​​of the detection liquid inside the collection hydraulic tank 2 and the storage tank 16. When the building changes the height of the collection hydraulic tank 2 during the settlement process, the detection value of the first pressure sensor 4 will be changed. At this time, the control center 26 can calculate the height difference change value of the first pressure sensor 4 according to the change of the detection value of the first pressure sensor 4, and at the same time, combined with the pressure value of the second pressure sensor 22, the building settlement value can be calculated. At the same time, the circulation component is set to circulate the detection liquid of the collection part and the control part, which effectively reduces the liquid temperature difference between the two parts, so that the calculated building settlement value is more accurate, and this set of equipment can perform unmanned real-time monitoring of the settlement of the building, obtain more accurate building settlement data, and ensure the safety and stability of the construction project.

[0036] During specific use, the second pressure sensor 22 detects the hydraulic value inside the liquid storage tank 16. Since the liquid storage tank 16 is set in a stable area, the detection value of the second pressure sensor 22 is basically stable. When the building settles and drives the collection hydraulic tank 2 to move, the detection value of the first pressure sensor 4 will change. At this time, according to the density and hydraulic value of the detection liquid, the height change value of the first pressure sensor 4 can be calculated. Then, the height change value of the first pressure sensor 4 and the height change value of the second pressure sensor 22 are comprehensively calculated to obtain the actual settlement value of the building.

[0037] See also Figure 2 - Figure 3As shown, an exhaust passage 5 connected to the atmosphere is provided at the top of the collection hydraulic tank 2, and a connecting rope 6 is connected inside the exhaust passage 5. A ball 7 for blocking the exhaust passage 5 is fixedly connected to the end of the connecting rope 6. The connecting rope 6 is made of elastic material. When there is gas inside the collection hydraulic pipe 2, the buoyancy of the detection liquid on the ball 6 is reduced. At this time, the ball 6 is separated from the exhaust passage 5, and the collection hydraulic tank 2 is connected to the atmosphere through the exhaust passage 5. At this time, the liquid storage tank 16 at a high place transports the detection liquid to the collection hydraulic tank 2 through the first liquid guide tube 9 and the second liquid guide tube 10. The detection liquid will squeeze out the air inside the collection hydraulic pipe 2. As the liquid level inside the collection hydraulic tank 2 rises, the detection liquid lifts up the ball 7 again to block the exhaust passage 5, which can effectively eliminate the influence of the gas in the detection liquid, so that the density of the detection liquid at each location is as equal as possible, thereby making the detection data of the first sensor 4 and the second sensor 22 more accurate.

[0038] See also Figure 1 - Figure 4 As shown, the lifting assembly includes a mounting plate 11 fixedly mounted on the ground, a guide rail 12 fixedly mounted on the mounting plate 11 and a mounting frame 13 slidably connected to the inside of the guide rail 12, a lead screw 14 threadedly connected to the mounting frame 13 is rotatably provided on the mounting plate 11, and the second mounting shell 15 is fixedly connected to the mounting frame 13.

[0039] In the entire set of settlement detection reference device, it is necessary to ensure that the liquid storage tank 16 is at an absolute high position relative to the collection hydraulic tank 2, so that the liquid storage tank 16 can transport the detection liquid to the inside of the collection hydraulic tank 2. Therefore, the user can rotate the screw 14 to drive the mounting frame 13 to slide inside the guide rail 12, and drive the position of the second mounting shell 15 to rise through the mounting frame 13, thereby adjusting the position of the liquid storage tank 16 to a high position, so that the detection liquid inside the liquid storage tank 16 can flow to the collection hydraulic tank 2 under the action of gravity.

[0040] See also Figure 4 - Figure 6 As shown, the liquid storage tank 16 is connected to an exhaust pipe 27 connected to the atmosphere to prevent gas accumulation inside the liquid storage tank 16 from causing errors in the detection values ​​of the first pressure sensor 4 and the second pressure sensor 22. The gas inside the liquid storage tank 16 can be discharged to the atmosphere through the exhaust pipe 27 to maintain the internal pressure environment of the liquid storage tank 16 at normal pressure.

[0041] The circulation component includes a mounting rod 18 slidably inserted on the liquid storage tank 16 and a pressure plate 19 fixedly installed at the end of the mounting rod 18, the pressure plate 19 is provided with a mounting hole 20, and a one-way flow regulating membrane 21 for regulating the flow of the mounting hole 20 is arranged inside the mounting hole 20, a motor 23 is fixedly connected to the inner wall of the second mounting shell 15, a turntable 24 is fixedly connected to the end of the output shaft of the motor 23, a connecting rod 25 is eccentrically hinged on the turntable 24, and the end of the connecting rod 25 is hinged to the mounting rod 18.

[0042] See also Figure 1 - Figure 6 As shown, the detection liquid is exchanged between the collection part and the control part through the first liquid guide tube 9 and the second liquid guide tube 10. In the actual installation process, the first liquid guide tube 9 and the second liquid guide tube 10 are in the external environment or buried underground. These installation methods will cause the detection liquid in the collection hydraulic tank 2, the first liquid guide tube 9, the second liquid guide tube 10 and the liquid storage tank 16 to be different in temperature, thereby causing the values ​​detected by the first pressure sensor 4 and the second pressure sensor 22 to be different from the actual values. At this time, the motor 23 can be started to drive the turntable 24 to rotate, and the turntable 24 drives the connecting rod 25 to rotate, and the connecting rod 25 drives the installation rod 18 to move up and down inside the liquid storage tank 16. The detection liquid under the liquid storage tank 16 flows to the second liquid guide tube 10, and the detection liquid inside the second liquid guide tube 10 flows to the collection hydraulic tank 2, and the detection liquid inside the collection hydraulic tank 2 flows to the first liquid guide tube 9, and the detection liquid in the first liquid guide tube 9 flows back to the liquid storage tank 16. When the mounting rod 18 drives the pressure plate 19 to move upward, the unidirectional flow regulating membrane 21 opens, and the detection liquid above and below the pressure plate 19 communicates with each other, so as to realize the mutual flow of the detection liquid inside the whole device, so that the temperature of the detection liquid in each place is consistent, and the inaccurate detection and collection data caused by the inconsistent temperature of the detection liquid in each place is effectively avoided.

[0043] See also Figure 4 - Figure 6As shown, the one-way flow regulating membrane 21 includes an upper mounting ring 211 fixedly connected to the mounting hole 20, a diastolic membrane 212 fixedly connected to the upper mounting ring 211, and a lower mounting ring 213 fixedly installed on the diastolic membrane 212. A support plate 214 is connected between the upper mounting ring 211 and the lower mounting ring 213 and is attached to the diastolic membrane 212 and is arranged in an arc shape. When the pressure plate 19 moves downward, the diastolic membrane 212 drives the support plate 214 to deform under the resistance of the detection liquid, thereby reducing the channel between the diastolic membrane 212. At this time, the pressure plate 19 The flow rate of the channel between the diastolic membrane 212 is less than the flow rate of the detection liquid flowing into the second liquid guiding tube 10, which can realize the flow of the detection liquid inside the entire device. When the mounting rod 18 drives the pressure plate 19 to move upward, the diastolic membrane 212 opens, and the support plate 214 bends and deforms outward. At this time, the channel between the diastolic membrane 212 becomes larger. Under the pressure of the pressure plate 19, the flow rate of the detection liquid exchanged through the channel of the diastolic membrane 212 is greater than the flow rate of the detection liquid flowing into the first liquid guiding tube 9. It is mainly that the detection liquid above and below the pressure plate 19 communicate with each other, thereby realizing the communication of the detection liquid inside the entire device.

[0044] The detection liquid is antifreeze liquid, which can prevent the detection liquid from freezing and blocking the first liquid guide tube 9 and the second liquid guide tube 10 in a low temperature use environment.
