Technical Field

[0001] The utility model relates to the technical field of civil engineering, and particularly relates to a pile foundation settlement detection device. Background Technique

[0002] A pile foundation refers to a deep foundation composed of piles and a pile cap (referred to as a cap) connecting the top of the piles, or a single-pile foundation connecting a column and a pile foundation. The role of the pile foundation is to transfer the load of the upper building to a deeper soil layer with stronger bearing capacity, or to compact the soft soil layer to improve the bearing capacity and density of the foundation soil. The pile foundation significantly improves the working efficiency of building construction, lays a relatively solid foundation for the building quality in the modern construction process, and promotes the overall improvement of the technology in the construction field of our country to a certain extent. The pile foundation is widely used in projects such as high-rise buildings, ports, bridges, etc., especially in the case of complex geological conditions, insufficient foundation bearing capacity or the need to support large buildings.

[0003] In high-rise buildings and large-scale civil engineering projects, the pile foundation, as an important load-bearing structure, its stability and safety are crucial. The detection of pile foundation settlement and offset is a key link to ensure project quality. At present, conventional detection methods mostly rely on professional instruments for indirect measurement, and then obtain the settlement distance and offset angle through complex calculations. This process not only takes a long time, but also has high technical requirements for operators, and it is difficult to obtain fast and intuitive detection results, affecting the overall working efficiency. Content of the Utility Model

[0004] In view of the existing deficiencies, the utility model provides a pile foundation settlement detection device, which solves the problems raised in the above background technique. This device can directly and accurately measure the settlement amount of the pile foundation, simplifies the detection process, and improves the detection efficiency.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A pile foundation settlement detection device includes a support frame, the support frame is of an inverted U-shaped structure, a suspension plate is fixedly arranged on the top side inside the support frame, a movable groove is formed inside the suspension plate, a support rod is arranged at the lower end inside the movable groove, the support rod is rotationally connected to the suspension plate through a first pin shaft, a heavy ball pendant is fixedly connected to the lower side of the left end of the support rod, a back plate is fixedly arranged on the right side of the support frame, scale lines are engraved on the front side of the back plate, the right end of the support rod is located in front of the back plate, and a marking assembly is arranged on the right side of the back plate.

[0007] Furthermore, a transparent protective cover is arranged on the front side of the back plate, and the right section of the support rod is located inside the transparent protective cover.

[0008] Furthermore, the marking component includes a fixed seat, an indicating piece, a sliding sleeve, an adjusting bolt, a vertical rod, and a sliding groove. The fixed seat is fixedly arranged on the right side of the back plate. A vertical rod is fixedly arranged on the front side of the fixed seat. A plurality of sliding sleeves are sleeved on the vertical rod. Horizontally structured indicating pieces are fixedly arranged on the left side of the circumferential surfaces of the plurality of sliding sleeves. The adjusting bolt is screwed through the right side of the circumferential surface of the sliding sleeve. A sliding groove is formed inside the right end face of the transparent protective cover. The indicating piece extends into the transparent protective cover through the sliding groove.

[0009] Furthermore, the length of the supporting rod in the area on the right side of the first pin shaft is greater than the length of the area on the left side of the first pin shaft, and the lengths of the supporting rods in the two areas are in an integer multiple relationship.

[0010] Furthermore, a rotatable second pin shaft is arranged through the right end of the supporting rod. A connecting rod is fixedly connected to the lower side of the second pin shaft. A pointer is arranged on the lower side of the connecting rod, and the lower end of the connecting rod is fixedly connected to the center of gravity of the pointer.

[0011] Furthermore, arc-shaped bottom plates are fixedly arranged at the lower ends of the left and right sides of the support frame. A plurality of ground inserting rods are uniformly fixedly arranged at the bottom of the bottom plates.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By utilizing the gravity of the heavy ball pendant and combining with the lever principle of the supporting rod, the utility model can monitor and record the settlement of the pile foundation in real time. When the pile foundation settles, the supporting rod will deflect accordingly, thereby driving the pointer to move on the scale line of the back plate. The change of the settlement amount can be visually observed. By directly observing the offset amount of the pointer at the right end of the supporting rod on the scale line of the back plate, the settlement information of the pile foundation can be intuitively and quickly obtained without relying on professional instruments and complex calculations. The detection process is simplified, the detection time is shortened, not only the detection efficiency is improved, but also the technical requirements for operators are reduced, and it has a wide application prospect.

[0014] 2. In the utility model, the length of the supporting rod in the area on the right side of the first pin shaft is greater than the length of the area on the left side of the first pin shaft, and the lengths of the supporting rods in the two areas are in an integer multiple relationship. Since the length of the right side area of the supporting rod is greater than that of the left side area, when the pile foundation settles and causes the supporting rod to deflect, the offset amount of the right side area will be relatively larger. This design can magnify the offset amount, enabling the operator to more easily observe and read the data on the scale line, thereby improving the detection sensitivity. And since the lengths of the supporting rods in the two areas are in an integer multiple relationship, this can simplify the subsequent data processing and calculation process. The operator can directly read the data on the scale line and use this integer multiple relationship to quickly calculate the settlement distance of the pile foundation.

[0015] 3. The marking component provided in the present utility model is used to mark the position of the right end of the support rod on the scale line at different time points, providing a reference for subsequent detection and facilitating an intuitive understanding of the settlement change of the pile foundation.

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment:

[0026] As Figures 1 to 7As shown in the figure, a pile foundation settlement detection device includes a support frame 1. The support frame 1 is of an inverted U-shaped structure. A suspension plate 5 is fixedly arranged on the top side inside the support frame 1. An activity groove 12 is formed inside the suspension plate 5. A support rod 10 is arranged at the lower end inside the activity groove 12. The support rod 10 is rotationally connected to the suspension plate 5 through a first pin shaft 9. A heavy ball pendant 4 is fixedly connected to the lower side of the left end of the support rod 10. A back plate 6 is fixedly arranged on the right side of the support frame 1. Scale lines 11 are engraved on the front side of the back plate 6. The right end of the support rod 10 is located in front of the back plate 6. A marking component 8 is arranged on the right side of the back plate 6. This design solves the problem that existing detection devices mostly rely on professional instruments for indirect measurement, and then obtain the settlement distance and deflection angle through complex calculations. This process not only takes a long time, but also has high technical requirements for operators, making it difficult to achieve fast and intuitive detection results and affecting the overall work efficiency.

[0027] In this embodiment, a transparent protective cover 7 is arranged on the front side of the back plate 6. The right section of the support rod 10 is located inside the transparent protective cover 7. The transparent protective cover 7 enables the operator to clearly observe the deflection of the support rod 10 on the scale lines 11 of the back plate 6, and at the same time can effectively protect the scale lines 11 on the back plate 6 from being eroded and damaged by the external environment, ensuring the clarity and accuracy of the scale lines 11, thereby improving the detection accuracy.

[0028] In this embodiment, the marking component 8 includes a fixed seat 81, an indicating piece 82, a sliding sleeve 83, an adjusting bolt 84, a vertical rod 85 and a sliding groove 86. The fixed seat 81 is fixedly arranged on the right side of the back plate 6. A vertical vertical rod 85 is fixedly arranged on the front side of the fixed seat 81. Multiple sliding sleeves 83 are sleeved on the vertical rod 85. Horizontal indicating pieces 82 are fixedly arranged on the left side of the circumferential surfaces of the multiple sliding sleeves 83. An adjusting bolt 84 is screwed through the right side of the circumferential surface of the sliding sleeve 83. A sliding groove 86 is formed inside the right end face of the transparent protective cover 7. The indicating piece 82 extends into the transparent protective cover 7 through the sliding groove 86. The arranged marking component 8 is used to mark the position of the right end of the support rod 10 on the scale lines 11 at different time points, providing a reference for subsequent detection and facilitating an intuitive understanding of the settlement change of the pile foundation.

[0029] In this embodiment, the length of the support rod 10 in the area on the right side of the first pin shaft 9 is greater than the length of the area on the left side of the first pin shaft 9, and the lengths of the support rod 10 in the two areas are in an integer multiple relationship. Since the length of the right side area of the support rod 10 is greater than that of the left side area, when the pile foundation settles and causes the support rod 10 to deflect, the deflection amount of the right side area will be relatively larger. This design can magnify the deflection amount, enabling the operator to more easily observe and read the data on the scale lines 11, thereby improving the detection sensitivity. And since the lengths of the support rod 10 in the two areas are in an integer multiple relationship, this can simplify the subsequent data processing and calculation process. The operator can directly read the data on the scale lines 11 and use this integer multiple relationship to quickly calculate the settlement distance of the pile foundation.

[0030] In this embodiment, a rotatable second pin shaft 15 is provided through the right end of the support rod 10. A connecting rod 14 is fixedly connected to the lower side of the second pin shaft 15. A pointer 13 is provided on the lower side of the connecting rod 14, and the lower end of the connecting rod 14 is fixedly connected to the center of gravity of the pointer 13. This design enables the connecting rod 14 and the pointer 13 to rotate relative to the support rod 10. When the support rod 10 deflects due to the settlement of the pile foundation, its right end will drive the connecting rod 14 and the pointer 13 to rotate and move accordingly. At the same time, the pointer 13 can maintain balance under the action of gravity and always remain in a horizontal state, facilitating the indication of the position on the scale line 11.

[0031] In this embodiment, arc-shaped bottom plates 2 are fixedly provided at the lower ends on both the left and right sides of the support frame 1. A plurality of groups of ground plug rods 3 are uniformly fixedly provided at the bottom of the bottom plates 2. The arc-shaped bottom plates 2 can better disperse and bear the pressure of the support frame 1, ensuring the stability of the entire device. At the same time, the plurality of groups of ground plug rods 3 further enhance the connection between the support frame 1 and the ground. The ground plug rods 3 can penetrate into the soil to provide additional anchoring force to prevent the support frame 1 from moving or overturning during the detection process.

[0032] The working principle of this pile foundation settlement detection device: In actual use, the device is fixed outside the pile foundation through the ground plug rods 3, and the heavy ball pendant 4 at the left end of the support rod 10 is made to fall on the upper end surface of the pile foundation. Then, a set of sliding sleeves 83 is moved downward so that the indicating piece 82 on the sliding sleeve 83 corresponds to the position of the pointer 13 at the right end of the support rod 10 on the scale line 11 for marking the initial position of the pile foundation. When the pile foundation settles, due to the gravitational force of the heavy ball pendant 4, the support rod 10 will deflect around the first pin shaft 9. The left end of the support rod 10 moves downward, and its right end moves upward, driving the pointer 13 to move at the same time. Since the length of the right side area of the support rod 10 is greater than that of the left side area, this design amplifies the deflection effect, making the movement of the pointer 13 on the scale line 11 of the back plate 6 more obvious. As the support rod 10 deflects, the town will move inside the transparent protective cover 7, and the new position of the right end of the support rod 10 on the scale line 11 of the back plate 6 will be marked in real time. In this way, the operator can intuitively understand the settlement situation of the pile foundation by observing the position change of the pointer 13.

[0033] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
