Description

Technical Field

[0001] This invention relates to the field of building settlement detection technology, and more specifically, to a building settlement detection device for testing the quality of building engineering projects. Background Technology

[0002] Construction settlement monitoring is a key technology to ensure engineering safety. It mainly monitors the settlement or deformation of the surrounding soil under load after the initial completion of the building, either due to its own weight or the influence of the construction environment. With the development of urban underground space and the increase of high-rise buildings, the settlement problem caused by construction is becoming increasingly prominent. If it is not warned in time, it may lead to structural cracking, pipeline breakage or even collapse, threatening life and property safety.

[0003] Currently, the main detection technology used is the hydrostatic level. However, hydrostatic levels can generally only detect the degree of settlement and cannot detect the tilt state. When the building is tilted rather than simply settled vertically, the hydrostatic level connected to the building is prone to tilting of the liquid level, resulting in false liquid level differences and affecting the accuracy of settlement detection.

[0004] How to invent a building settlement detection device for construction engineering quality inspection to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0015] Preferably, the first drain pipe is designed to be close to the connecting pipe, and the second drain pipe is located on the other side wall of the outer ring away from the first drain pipe.

[0023] 1. By rotating the spherical body and cavity and cooperating with the counterweight, the liquid level is kept vertical, preventing tilting and ensuring detection accuracy. At the same time, when tilting, the inner ring compresses the liquid bladder, and the hydraulic medium drives the rotating ring to rotate, performing all-round automatic detection of the tilt direction. When the rotation reaches the tilt direction, the pressure is released through the connection between the connecting groove and the annular groove.

This achieves all-round automatic detection of the tilt direction and tilt degree, with no detection angle limitation and high degree of freedom in detection.

[0024] 2. The conical groove and conical valve work together to buffer the settling detection fluid path inside the counterweight tube. Spring 1 buffers the tilt detection fluid path inside the sealed chute. When the tilt angle is large, the rotation of the rotating ring 2 releases the limiting block, and springs 1 and 2 become connected in series, reducing the elastic coefficient and further improving the buffering and shock absorption effect on the fluid path inside the sealed chute. At the same time, the flow diameter of the iris mechanism is reduced by adjusting the rotating ring 2, further reducing the impact of vibration on the fluid path inside the counterweight tube, effectively improving the accuracy and shock resistance of the overall settling and tilt detection.

The top of the outer ring 400 is provided with an observation post 2 406. The observation post 2 406 is fitted with a sealing plug 2 407 and a switch 2 408. The bottom of the observation post 2 406 is provided with a return pipe for resetting that is connected to the sealing slide groove 413. The rotating ring 1 403 is provided with a connecting groove 411 that connects the sealing slide groove 413 and the annular groove 409.

[0044] The energy storage ring 404 stores and releases the stress generated by the tilt. The energy storage ring 404 is sleeved on the outer wall of the counterweight tube 303. A rotating ring 419 is sleeved inside the energy storage ring 404. The side wall of the rotating ring 419 is provided with a sealing block 418 that cooperates with the inner side wall of the energy storage ring 404 to drive the rotating ring 419 to rotate. A spring 424 and a spring 426 are connected between the sealing block 418 and the energy storage ring 404. A connecting block 425 is provided between the spring 424 and the spring 426. A protrusion 427 and a locking block 428 are provided inside the energy storage ring 404 to restrict the movement of the connecting block 425.

[0045] The connecting component includes a connecting pipe 414 and a liquid supply pipe 417 located inside the outer ring 400. The two ends of the connecting pipe 414 are connected to the liquid bladder 401 and the sealing groove 413, respectively. The two ends of the liquid supply pipe 417 are connected to the sealing groove 413 and the annular groove 409, respectively. The side walls on both radial sides of the sealing groove 413 are respectively provided with a first drain pipe 415 and a second drain pipe 416 that are connected to the inner cavity of the storage ring 404. The storage ring 404 is also provided with a secondary damping mechanism.

[0046] Furthermore, a connecting block 431 is fitted inside the connecting groove 411. The connecting block 431 has a set of rectangular slots that cooperate with the connecting groove 411. The side of the connecting block 431 close to the axis of the rotating ring 403 is constructed of a magnet. A spring is provided between the connecting block 431 and the connecting groove 411. A magnetic ring 430 is provided on the inner side of the annular groove 409, which is radially magnetized and attracts the connecting block 431.

[0047] It should be noted that the design position of drain pipe 1 415 is close to the connecting pipe 414, and the setting position of drain pipe 2 416 is on the other side wall of the outer ring 400 away from drain pipe 1 415. The inner diameter of drain pipe 1 415 is smaller than the inner diameter of drain pipe 2 416, and the inner diameter of supply pipe 417 is larger than the inner diameter of drain pipe 1 415 and the inner diameter of drain pipe 2 416.

[0048] Reference Figure 1-3 The settlement detection mechanism includes a pressure piston 305 fitted inside the detector 301. An observation column 302, communicating with the detector 301, is located on the top of the detector 301. A sealing plug 306 and a switch 307 are fitted inside the observation column 302. A spring is installed between the switch 307 and the inner top of the observation column 302. A light-phase hydraulic medium is filled between the sealing plug 306 and the pressure piston 305. The pressure piston 305 is connected to the detector 200 via a hose. A pressure piston 201 is fitted inside the detector 200. The pressure piston 201 and pressure piston 305... The space between the two sections is filled with a heavy-phase hydraulic medium. It should be noted that the heavy-phase medium is preferably a silicone oil solution, which can suppress and reduce the impact of vibration through its density and viscosity advantages. The light-phase medium is preferably a low-viscosity kerosene solution, which avoids the capillary effect that occurs when the high-viscosity, high-density heavy-phase solution flows inside the small-diameter observation column 302. Thus, the stability of the detection is improved through the flow and feedback of the light-phase medium. It should also be noted that both switch 307 and switch 408 are equipped with alarm devices that are electrically connected to the outside. When triggered by contact pressure, they can issue an alarm to remind that the settlement or tilting threshold has been reached, and remind the staff to assess and remedy the construction in a timely manner.

[0049] Furthermore, the mass of pressure piston 201 is greater than that of pressure piston 305. In the initial state, the bottom of pressure piston 305 is flush with the bottom of pressure piston 201. It should be noted that in the initial state, a heavy phase medium is filled inside detector 301 and detector 200, and then a light phase medium is filled between pressure piston 305 and sealing plug 306. The counterweight of pressure piston 201 is then adjusted so that the bottom of pressure piston 305 is flush with the bottom of pressure piston 201 in the initial state to achieve calibration.

[0050] Reference Figure 3-6The buffer mechanism includes a conical groove 421 disposed inside the counterweight tube 303. The bottom of the conical groove 421 is provided with a conical opening. A conical valve 422 is disposed at the bottom of the conical groove 421. A conical plug is disposed at the top of the conical valve 422, which is connected to the conical opening of the conical groove 421. The liquid medium below the conical valve 422 enters the gap between the conical groove 421 and the conical valve 422 through the flow ring opened inside the conical valve 422 and the gap between the conical valve 422 and the counterweight tube 303, and flows with the liquid above the conical groove 421. An elastic shaft 423 is disposed between the conical valve 422 and the conical groove 421. The elastic shaft 423 is fitted with the conical groove 421 in a limited movement, and a spring is disposed between the elastic shaft 423 and the conical groove 421.

[0051] Reference Figure 3-8 The secondary shock absorption mechanism includes an iris mechanism 420 located inside the counterweight tube 303. A rotating ring 419 is connected to the iris mechanism 420. The iris mechanism 420 is based on existing iris technology. The fixed end of the iris mechanism 420 is connected to the inner wall of the counterweight tube 303. The rotating adjustment end of the iris mechanism 420 is fixedly connected to the rotating ring 419. A hydraulic groove 432 is provided inside the energy storage ring 404. The hydraulic groove 432 is filled with hydraulic medium. A protrusion 427 is sleeved at one end of the hydraulic groove 432. A push block 429 is sleeved at the other end of the hydraulic groove 432. A spring is provided inside the energy storage ring 404 to push the locking block 428 and the protrusion 427 to reset. The side of the locking block 428 away from the protrusion 427 is provided with a chamfer that cooperates with the connecting block 425. The end of the protrusion 427 extending into the energy storage ring 404 is a semi-circular design.

[0052] Furthermore, the interior of the locking block 428 is hollow and has a set of inclined blocks. The end of the push block 429 facing the locking block 428 is provided with an angle that cooperates with the inclined blocks. The locking block 428 and the accumulator ring 404 are designed with a sealed sliding mechanism. The outer wall of the accumulator ring 404 is provided with a set of air passage valves 433 that are connected to the locking block 428. The air passage valves 433 are provided with an intake valve and an exhaust valve, and the diameter of the exhaust valve is smaller than the diameter of the intake valve.

[0053] Furthermore, the spring constant of spring 1 424 is greater than that of spring 2 426.

[0054] The working process of this building settlement detection device for building engineering quality inspection is as follows:

[0055] After selecting a reference point, fix the detection body 100 to the building to be tested. Then, select a distant point and fix it to the bedrock by anchoring it deep into the ground. Then fix the detector 200 to the anchor to form a fixed reference point. It should be noted that in the initial state of installation, the detector 200, the detection body 100, and the detector 301 are all in a standard vertical state without tilting. At the same time, adjust the counterweight of the pressure piston 201 so that the bottom of the pressure piston 201 is level with the bottom of the pressure piston 305, that is, the level of the heavy phase medium inside the detector 301 and the detector 200.

[0056] When the building settles, the position of the detection body 100 decreases synchronously, while the detector 200, which is fixed to the bedrock by anchor bolts, remains in its initial position. As the positions of the detection body 100 and detector 301 decrease, and the liquid medium between detector 301 and detector 200 is connected, the liquid medium inside detector 200 flows into detector 301 under the principle of connection and liquid circuit balance. The pressure piston 305 rises, pushing the medium above pressure piston 305 into the smaller diameter observation column 302, thereby amplifying the display of the liquid level change of pressure piston 305 for easy observation. Moreover, the design of the sealing plug 306, pressure piston 305, and pressure piston 201 prevents the liquid medium from flowing randomly, reduces the impact of vibration and wall adhesion during flow on the detection results, reduces errors, and improves detection accuracy.

[0057] Meanwhile, when the building tilts, the spherical body 300 can rotate in any direction inside the spherical cavity 101 through the spherical hinge shaft formed by the spherical body 300 and the spherical cavity 101. With the help of the counterweight 304 and the counterweight of the counterweight 304, the detector 301 always remains vertically upward, effectively avoiding the influence of the tilt of the liquid level inside the detector 301 on the readings and results of the settlement detection when it is tilted.

[0058] Furthermore, when the building tilts, the detection body 100, outer ring 400, and counterweight pipe 303 tilt synchronously in the direction of building tilt. The counterweight pipe 303 remains vertical under the action of the counterweight. Through the relative movement of the counterweight pipe 303 and outer ring 400, the inner ring 402 connected to the counterweight pipe 303 slides inside the outer ring 400, pushing the liquid bladder 401 to compress. The hydraulic medium inside the liquid bladder 401 is pressurized and enters the sealing groove 413 through the connecting pipe 414, and further enters the storage ring 404 through the drain pipe 415, pushing the sealing block 418 and the rotating ring 419 to rotate and compress the spring 424 to store energy. Furthermore, since the inner diameter of the drain pipe 415 is smaller than the inner diameter of the drain pipe 416, the resistance encountered during flow is slightly... The medium is large, so it is divided within the sealing groove 413. One part enters the accumulator ring 404 directly through the drain pipe 415, and the other part flows along the gap between the rotating ring 403 and the sealing groove 413. The blade 412 pushes the rotating ring 403 to rotate and enters the accumulator ring 404 through the larger inner diameter drain pipe 416 on the other side. Together, they act on the sealing block 418. During the rotation of the rotating ring 403, the connecting groove 411 rotates synchronously. When the connecting groove 411 rotates to a position close to the tilted movement of the inner ring 402, the annular groove 409 on the tilted side moves closer to the connecting groove 411 and connects with it. At this time, the hydraulic medium inside the sealing groove 413 and the accumulator ring 404 flows through the groove. The flow from the annular groove 409 into the connecting groove 411 is as the rotating ring 403 rotates. The magnetic ring 430 is radially magnetized. Under the magnetic attraction of the magnetic ring 430, the closer the connecting block 431 is to the magnetic ring 430, the greater the magnetic influence, causing it to move closer to the annular groove 409. This increases the overlap between the rectangular groove of the connecting block 431 and the connecting groove 411, thus increasing the flow cross-sectional area. The increased flow cross-sectional area of ​​the connecting groove 411 allows the solution inside the sealing groove 413 and the storage ring 404 to be further diverted through the drain pipe 415 and the supply pipe 417 into the connecting groove 411 and then into the observation column 406, pushing the sealing plug 407 to move. The liquid level height of the sealing plug 407 indicates the degree of displacement. Simultaneously, due to the... Initially, the annular groove 409 and the connecting groove 411 are not connected. When the inner ring 402 tilts synchronously in one direction with the building and the detection body 100, the inner ring 402 and the outer ring 400 will move relative to each other in that tilting direction. That is, the inner ring 402 moves in the tilting direction. When the rotating ring 403 rotates under the transmission of the pressure medium inside the liquid bladder 401, when the connecting groove 411 rotates to the tilt offset direction of the inner ring 402, it can contact and connect with the annular groove 409 at that point, thus starting to discharge liquid through the connecting groove 411. At this time, the hydraulic medium flows through the connecting groove 411 to release pressure. Since the pressure relief channel supply pipe 417 is added at this time, the liquid dynamics inside the sealing slide 413 are reduced. When the tilting continues, causing the liquid bladder 401 to continue to compress,Liquid enters the observation column 406 directly through the supply pipe 417. The remaining liquid power enters the storage ring 404 through the drain pipe 415, and will no longer drive the rotating ring 403. Therefore, the device maintains a vertical position through the rotation of the spherical body 300 and the spherical cavity 101, as well as the cooperation of the counterweight 304, preventing liquid level tilting and ensuring detection accuracy. Simultaneously, when tilting, the inner ring 402 compresses the liquid bladder 401, driving the rotating ring 403 to rotate via hydraulic medium for omnidirectional automatic detection of the tilt direction. When the tilt direction is reached, pressure is released through the connection between the connecting groove 411 and the annular groove 409, stopping the rotating ring 403. The direction pointed to by the pointer 410 is the tilt direction. This achieves omnidirectional automatic detection of the tilt direction and degree, with a high degree of freedom in detection.

[0059] It should be noted that only when the inner ring 402 moves to a certain extent under the offset, so that the distance between the annular groove 409 and the magnetic ring 430 reaches a certain level, can the magnetic force of the magnetic ring 430 be sufficient to drive the connecting block 431 to move. The movement of the connecting block 431 releases the blockage on the connecting groove 411. At the same time, when the rotating ring 403 rotates closer to the shortest distance between the connecting block 431 and the magnetic ring 430, the magnetic force on the connecting block 431 is greater, the overlapping area of ​​the rectangular groove of the connecting block 431 and the connecting groove 411 is larger, and the resistance encountered by the liquid supply pipe 417 in the flow through the connecting groove 411 is smaller. When the rotating ring 403 stops rotating, the liquid supply pipe 417 can stably supply liquid to the connecting groove 411.

[0060] Furthermore, when noise and vibration generated during construction act on the spherical body 300, under normal circumstances, the medium flows through the gap between the conical groove 421 and the conical valve 422. When vibration occurs, because the conical valve 422 and the conical groove 421 are connected by an elastic shaft 423, and the elastic shaft 423 is in a limiting sliding connection with the conical groove 421, the gap between the conical groove 421 and the conical valve 422 can only decrease, compressing the spring between the elastic shaft 423 and the conical groove 421. The gap between the conical groove 421 and the conical valve 422 cannot increase under the limiting action of the elastic shaft 423. Therefore, during vibration, the gap between the conical groove 421 and the conical valve 422 decreases periodically, increasing the resistance of the medium as it passes through, which to some extent... This achieves a damping and shock absorption effect. Furthermore, when the tilt is large, the inner ring 402 continuously compresses the liquid bladder 401, causing the liquid inside the liquid bladder 401 to be continuously discharged through the connecting pipe 414 into the sealing groove 413. Due to the limited diameter and discharge capacity of the connecting groove 411 and the supply pipe 417, part of the liquid entering the sealing groove 413 is discharged through the supply pipe 417 into the observation column 406, and the other part enters the storage ring 404 under the action of reduced liquid pressure, pushing the rotating ring 419 to rotate and compressing the spring 424. When the sealing block 418 rotates to pass the protrusion 427, it pushes the protrusion 427, which in turn drives the push block 429. The angled edge of 429 engages with the inner angled block of 428, pushing 428 towards the inside of the energy storage ring 404. This causes 428 to disengage from the connecting block 425. At this point, spring 424, connecting block 425, and spring 426 form a series of springs. Since the elastic coefficient of spring 424 is greater than that of spring 426, the elastic coefficient of the spring group decreases after being connected in series. It should be noted that in the initial state, connecting block 425 is engaged with 428, and the energy storage ring 404 provides energy storage and compression to the liquid through spring 424. At the same time, spring 424 provides a certain buffering effect on the internal liquid passage of the sealing groove 413, reducing the impact of external vibration on the internal liquid passage. When... When the locking block 428 retracts, the elastic coefficient of the series spring group decreases, which can provide a greater degree of fluid buffering for the internal fluid path of the sealing groove 413. This prevents accidental activation of switch 408 under the influence of vibration when the tilt is large and the sealing plug 407 is in a high position. At the same time, since tilting is generally accompanied by settlement, the larger the tilt, the greater the rotation amplitude of the rotating ring 419. The rotating ring 419 drives the rotating tube adjustment end of the iris mechanism 420 to rotate, reducing the flow diameter of the iris mechanism 420 and increasing the fluid resistance inside the counterweight tube 303. This further limits the fluid impact caused by vibration, effectively reducing the impact of vibration on settlement detection and preventing the sealing plug 306 from accidentally activating switch 307 under vibration.

[0061] It should be noted that, through the design of the large-diameter exhaust valve and small-diameter intake valve of the air circuit valve 433, after the push block 429 pushes the locking block 428 back, the locking block 428 resets slowly due to the slow intake speed of the intake valve. This allows the spring 1 424, the connecting block 425, and the spring 2 426 to maintain the state of the series spring group for a long time after the liquid inside the sealing slide groove 413 and the accumulator ring 404 enters the observation column 2 406. After reaching a certain degree of tilt, the elastic coefficient is reduced, and the buffering effect on the liquid circuit is improved.

[0062] It should be noted that after the pressure of the liquid inside the accumulator ring 404 stabilizes, when the liquid bladder 401 stops draining, the liquid is slowly drained through the drain pipe 415 into the sealing groove 413 by the elastic force of the spring 424 and the spring 426, and then enters the observation column 406 or the liquid bladder 401 to reset.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
