Description

Technical Field

[0001] This application relates to the technical field of engineering detection, and more particularly, to a pile foundation settlement monitoring device. Background Art

[0002] Pile foundation settlement refers to the phenomenon that the top of the pile generates a vertical displacement relative to the ground due to the compression deformation of the soil mass or the sinking of the pile itself after the pile foundation bears the load. Pile foundation settlement is a complex engineering problem, which involves various factors such as geological conditions, pile design and construction, load magnitude and distribution, etc. During engineering detection, it is necessary to measure whether the pile foundation settlement is within a reasonable range to ensure the quality and safety of the building.

[0003] For example, a pile foundation settlement detection ruler with the patent number (CN203905068U) includes a ruler body, a high-precision inclination sensor installed on the ruler body, a rotating shaft on one side of the ruler body, a simple support point on the other side of the ruler body, and a reference pile below the rotating shaft. It is characterized in that the pile foundation settlement detection ruler further includes a level installed on the ruler body, the simple support point can move left and right, and a scale is provided on the ruler body.

[0004] In the above structure, a triangular structure formed by the ruler body, the reference pile, and the distance between the reference pile and the simple support point is used to calculate the sinking height of the simple support point according to the inclination angle of the ruler body. This structure cannot directly show the numerical value of the pile foundation settlement and is inconvenient to read.

[0005] In view of this, the purpose of the present utility model is to design a pile foundation settlement monitoring device with more intuitive detection data. Content of the Utility Model

[0006] The content part of this application is used to briefly introduce the concepts, which will be described in detail in the following specific implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] To solve the technical problems mentioned in the above background art part, some embodiments of this application provide a pile foundation settlement monitoring device, including:

[0008] A reference box, detachably and fixedly installed on a reference pile;

[0009] A telescopic ruler set, arranged on the reference box;

[0010] A reel, rotatably arranged on the telescopic ruler set, and a measuring tape is wound on the reel;

[0011] The fixed seat is detachably and fixedly installed on the pile foundation and is fixedly connected to the tape measure. When the fixed seat moves downward, it can drive the reel to rotate and release the tape measure.

[0012] During the working process, the reference box is fixedly arranged on the reference pile. The telescopic ruler set is stretched to one side of the pile foundation, and the first clamping screw is rotated to clamp the fixed seat on the pile foundation, and the length of the tape measure extended is recorded. After the monitoring device is placed for a period of time, the extended length of the tape measure is recorded again, and the settlement value of the pile foundation can be measured. The setting of the tape measure can directly read the settlement value of the pile foundation, which is convenient for the staff to record.

[0013] Further, the telescopic ruler set includes a first sleeve plate, a second sleeve plate movably arranged in the first sleeve plate, and a third sleeve plate movably arranged in the second sleeve plate. The first sleeve plate is arranged on the reference box, and the reel is rotatably arranged on the third sleeve plate.

[0014] Further, a first limiting screw is inserted through one end of the first sleeve plate close to the second sleeve plate, and the first limiting screw is threadedly connected to the first sleeve plate;

[0015] A second limiting screw is inserted through one end of the second sleeve plate close to the third sleeve plate, and the second limiting screw is threadedly connected to the second sleeve plate.

[0016] Further, two oppositely arranged support seats are fixedly arranged at one end of the third sleeve plate far from the second sleeve plate. A fixed shaft is fixedly arranged on the support seat, and the reel is rotatably arranged outside the fixed shaft. A torsion spring is arranged between the fixed shaft and the reel. One end of the torsion spring is fixedly connected to the reel, and the other end is fixedly connected to the fixed shaft.

[0017] Further, a support member is fixedly arranged on the bottom surface of the third sleeve plate. The support member includes a bottom rod and a support screw telescopically arranged in the bottom rod. The bottom rod is fixedly arranged on the bottom surface of the third sleeve plate, the support screw is threadedly connected to the bottom rod, and the bottom surface of the support screw is fixedly provided with a support foot.

[0018] Further, a mounting plate is fixedly arranged at one end of the first sleeve plate far from the second sleeve plate, and the mounting plate is rotatably arranged on the top surface of the reference box.

[0019] Further, the fixed seat is a plate-shaped seat with a U-shaped cross section. The first clamping screw is inserted through two opposite side walls of the fixed seat, and the first clamping screw is threadedly connected to the fixed seat. A first clamping plate is fixedly arranged at one end of the first clamping screw close to the pile foundation.

[0020] Further, a second clamping screw is inserted through any side wall of the reference box, and the second clamping screw is threadedly connected to the side wall of the reference box. A second clamping plate is fixedly arranged at one end of the second clamping screw located inside the reference box.

[0021] The beneficial effects of the present application are as follows:

[0022] 1. Since a tape measure is provided, the fixed seat fixed on the pile foundation will settle along with the pile foundation. During the settlement process of the fixed seat, the tape measure will be pulled out, thereby measuring the settlement value of the pile foundation and enabling the staff to read the settlement value more intuitively.

[0023] 2. Since it takes a long time to monitor the settlement value of the pile foundation, the fixed seat is fixed on the pile foundation by the first clamping screw, which can prevent the position of the monitoring device from being changed due to accidental touch, thus affecting the accuracy of the measurement data.

[0024] 3. The setting of the torsion spring can tension the tape measure and improve the accuracy of the tape measure measurement.

[0025] 4. The mounting plate is rotatably arranged on the reference box, which is convenient for rotating the fixed seat to a position convenient for fixing on the pile foundation to be measured when the selected reference pile and the pile foundation to be measured are not parallel.

[0039] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0040] A pile foundation settlement monitoring device includes a reference box 1 detachably and fixedly installed on a reference pile. A telescopic ruler set 2 is arranged on the top surface of the reference box 1. A reel 3 is rotatably arranged on the telescopic ruler set 2. A measuring tape 4 is wound on the reel 3. One end of the measuring tape 4 is fixedly connected to the reel 3, and the other end hangs downwards and is fixedly connected to a fixed seat 5. The fixed seat 5 is detachably and fixedly installed on the pile foundation. Specifically, the fixed seat 5 is a plate-like structure with a U-shaped cross section. A first clamping screw 6 is inserted through two opposite side walls of the fixed seat 5. The first clamping screw 6 is threadedly connected to the fixed seat 5. A first clamping plate 7 is fixedly arranged at one end of the first clamping screw 6 close to the pile foundation, and a first knob block 8 is fixedly arranged at the other end.

[0041] A second clamping screw 9 is inserted through a side wall of the reference box 1. The second clamping screw 9 is threadedly connected to the reference box 1. A second clamping plate 10 is fixedly provided at one end of the second clamping screw 9 located inside the reference box 1, and a second knob block 11 is fixedly provided at the other end.

[0042] Rotating the second clamping screw 9 can make the second clamping plate 10 contact the reference pile, thereby fixing the reference box 1 on the reference pile; rotating the first clamping screw 6 can drive the first clamping plate 7 to contact the pile to be measured, thereby fixing the fixed seat 5 on the pile. When the pile sinks downward, the fixed seat 5 will sink together with the pile. After the fixed seat 5 moves downward, it can pull out the tape measure 4 from the reel 3, thereby measuring the value of the pile settlement.

[0043] Specifically, the telescopic ruler set 2 includes a first sleeve plate 12, a second sleeve plate 13 movably arranged inside the first sleeve plate 12, and a third sleeve plate 14 movably arranged inside the second sleeve plate 13; one end of the first sleeve plate 12 away from the second sleeve plate 13 is fixedly provided with a mounting plate 15. The mounting plate 15 is rotatably arranged on the top surface of the reference box 1, and a steering block 16 is fixedly provided on the mounting plate 15 for easy rotation; when the reference pile and the pile to be measured are not parallel, rotating the steering block 16 can drive the telescopic ruler set 2 to rotate to a position suitable for fixing the fixed seat 5 on the pile.

[0044] More specifically, a first limit screw 17 is inserted through one end of the first sleeve plate 12 close to the second sleeve plate 13. The first limit screw 17 is threadedly connected to the first sleeve plate 12; a second limit screw 18 is inserted through one end of the second sleeve plate 13 close to the third sleeve plate 14. The second limit screw 18 is threadedly connected to the second sleeve plate 13; rotating the first limit screw 17 can make the first limit screw 17 press the second sleeve plate 13 tightly inside the first sleeve plate 12, thereby fixing the telescopic length of the second sleeve plate 13. The function of the second limit screw 18 is the same as that of the first limit screw 17.

[0045] More specifically, two relatively arranged support seats 19 are fixedly provided at one end of the third sleeve plate 14 away from the second sleeve plate 13. A fixed shaft 20 is fixedly arranged between the two support seats 19. Both ends of the fixed shaft 20 are inserted through the support seats 19, and thread lines are formed at both ends of the fixed shaft 20 for facilitating the use of nuts to fix the position of the fixed shaft 20; the reel 3 is rotatably arranged outside the fixed shaft 20, and a torsion spring 21 is arranged between the fixed shaft 20 and the reel 3. One end of the torsion spring 21 is fixedly connected to the reel 3, and the other end is fixedly connected to the fixed shaft 20; the torsion spring 21 can give the reel 3 a restoring force to the initial position. When the fixed seat 5 moves downward, it pulls the reel 3 to rotate, thereby releasing the tape measure 4. The setting of the torsion spring 21 can keep the tape measure 4 always in a tensioned state, improving the measurement accuracy.

[0046] Further, two support members 22 are fixedly arranged on the bottom surface of the third template 14. The support member 22 includes a bottom rod 23 and a support screw rod 24 telescopically arranged in the bottom rod 23. The bottom rod 23 is fixedly arranged on the bottom surface of the third template 14. The support screw rod 24 is threadedly connected to the bottom rod 23. A support foot 25 is fixedly arranged on the bottom surface of the support screw rod 24. Rotating the support screw rod 24 can extend or retract the support screw rod 24 into or out of the bottom rod 23, so as to support the telescopic ruler set 2 on the pitted ground, and avoid bending of the telescopic ruler set 2 when the extended length is relatively long or excessive pressure on the reference box 1.
