Description

Technical Field

[0001] This utility model relates to the field of site backfill measurement technology, specifically to a site backfill soil elevation control pile structure. Background Technology

[0002] In the fields of civil engineering, building engineering, and site development, backfilling of large-area sites (such as plazas, storage yards, parking lots, and factory floors) is a crucial foundational step. The quality of the backfill, especially the accuracy of its final design elevation, directly affects the flatness, drainage, functionality, and overall quality and safety of the subsequent superstructure construction. Therefore, real-time and effective monitoring and control of the elevation during backfilling is a key step in ensuring that the site meets design requirements.

[0003] Currently, the most common method for controlling the elevation of backfill soil is to use a level instrument in conjunction with a leveling rod for manual measurement. However, this method has certain shortcomings. Firstly, the measurement efficiency is low. Although the level instrument measurement is relatively accurate, the operation process is cumbersome, requiring professionals to repeatedly set up the instrument, take readings, and calculate. After each backfilling, multiple points need to be remeasured, which consumes a lot of effective construction time and significantly slows down the backfilling progress. Secondly, it is difficult to control the benchmark of multiple control piles. Due to factors such as the initial driving depth and ground undulation, the "zero starting point" (usually the top of the pile or a fixed point) height of different control piles may be inconsistent. It is difficult to uniformly adjust them to the same absolute design benchmark height (i.e., uniform zero scale), which further reduces the accuracy and reliability of multi-pile collaborative control of elevation. Therefore, a device is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a structure for controlling the elevation of backfill soil, which solves the problems of low backfilling efficiency caused by the need for multiple measurements during the existing backfilling process and the difficulty in adjusting the coordinated dimensions of the control piles.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a site backfill soil elevation control pile structure, including positioning piles, measuring piles, and a retaining wall built on the ground to enclose the positioning piles and measuring piles, wherein the retaining wall is used to reduce the impact of the backfilling process on the positioning piles;

[0006] The positioning stakes are set inside the retaining wall and buried in the ground. The measuring stakes are detachably set on one side of the positioning stakes through an adjustment mechanism. The surface of the measuring stakes is provided with scale lines to check the backfill height.

[0007] An adjustment groove is provided on the outer surface of the measuring stake. A slider is slidably connected inside the adjustment groove. A storage box is fixedly connected to the back of the slider. A connecting mechanism is provided inside the storage box to connect adjacent measuring stakes.

[0008] Optionally, the adjusting mechanism includes a connecting plate, a threaded rod, and a fixing nut. The connecting plate is fixedly connected to one side of the positioning pile, the threaded rod is fixedly connected to one side of the connecting plate and passes through the measuring pile, and the fixing nut is threadedly connected to one end of the threaded rod and fits against one side of the measuring pile.

[0009] Optionally, the measuring pile has a guide groove on its side along the length of the measuring pile, and the threaded rod slides within the guide groove to adjust the relative height between the positioning pile and the measuring pile.

[0010] Optionally, the connecting mechanism includes a winding roller and a connecting wire. The winding roller is rotatably disposed inside the storage box, and the connecting wire is wound around the outer surface of the winding roller. One end of the connecting wire away from the winding roller is connected to another measuring stake.

[0011] Optionally, a slot is provided on one side of the slider, and a buckle adapted to the slot is fixedly connected to the end of the connecting line away from the winding roller. The buckle and the slot are detachably connected.

[0012] Optionally, a turntable is provided on one side of the storage box. One end of the turntable is fixedly connected to the winding roller via a connecting shaft to drive the winding roller to rotate. A ratchet is provided on the outer surface of the turntable. A pawl is rotatably connected to the back of the storage box via a torsion spring. The pawl is adapted to the ratchet to limit the rotation direction of the ratchet.

[0013] Optionally, the interior of the retaining wall is filled with concrete to fix the position of the positioning piles, and a fence is fixedly connected to the top of the retaining wall.

[0014] Optionally, ground nails are fixedly connected to the lower surface of the positioning pile to improve its stability.

[0015] This utility model provides a structure for controlling the elevation of backfill soil at a construction site, which has the following beneficial effects:

[0016] This utility model provides a structure for controlling the elevation of backfill soil at a construction site. Through the coordinated arrangement of measuring stakes, a storage box, and a connecting mechanism, a connecting line can be stretched between adjacent measuring stakes, allowing for a more intuitive view of the backfill height between the stakes. This makes measurement more convenient, reduces the frequency of instrument measurements during backfilling, and thus improves backfilling efficiency. The coordinated arrangement of a slider and a scale line allows for adjustment of the slider's height during backfilling, thereby adjusting the height of the connecting line between adjacent measuring stakes, making elevation monitoring more convenient and accurate. The coordinated arrangement of positioning stakes, measuring stakes, and an adjustment mechanism allows for adjustment of the zero-scale line of the measuring stakes. In use, the zero-scale lines of multiple measuring stakes can be adjusted to the same height, further improving the accuracy during backfilling. Furthermore, the external retaining wall can enclose the measuring stakes, reducing collisions caused by backfill soil during backfilling and preventing tilting of the measuring stakes that could decrease measurement accuracy.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a site backfill soil elevation control pile structure, including a positioning pile 1, a measuring pile 2, and a retaining wall 3 built on the ground to enclose the positioning pile 1 and the measuring pile 2. The retaining wall 3 is used to reduce the impact of the backfilling process on the positioning pile 1.

[0026] Positioning stake 1 is located inside the retaining wall 3 and buried in the ground. Measuring stake 2 is detachably installed on one side of positioning stake 1 through an adjustment mechanism. The surface of measuring stake 2 is provided with scale lines to check the backfill height.

[0027] The outer surface of the measuring stake 2 is provided with an adjustment groove 19. The slider 4 is slidably connected inside the adjustment groove 19. The back of the slider 4 is fixedly connected with a storage box 5. The storage box 5 is provided with a connecting mechanism inside to connect adjacent measuring stakes 2.

[0028] Positioning stake 1 can be buried in the soil to initially position and fix the measuring stake 2 on one side. The relative height between the measuring stake 2 and the positioning stake 1 can be adjusted by adjusting the adjustment mechanism, thereby adjusting the zero scale of multiple measuring stakes 2 at different positions to the same height. The outer retaining wall 3 can protect the positioning stake 1 and measuring stake 2 in the middle, reducing the pressure of the soil on the measuring stake 2 during backfilling, and preventing the measuring stake 2 from tilting and causing accuracy deviation. The slider 4 can slide up and down along the adjustment groove 19. When backfilling, the slider 4 can be adjusted to the current backfilling height. After backfilling is completed, the slider 4 can be raised to the next backfilling height, making the backfilling process more accurate. The connecting mechanism in the storage box 5 can connect adjacent measuring stakes 2. After connection, the current backfilling height and the height difference between different positions can be viewed more intuitively, which is convenient for construction personnel to make timely adjustments. The slider 4 is equipped with bolts and nuts on the side. By tightening the nuts, the slider 4 can be fixed in the adjustment groove 19. The slider 4 is provided with a triangular protrusion on the side near the scale to indicate the current height.

[0029] In this embodiment, as a preferred option, the adjustment mechanism includes a connecting plate 6, a threaded rod 7, and a fixing nut 8. The connecting plate 6 is fixedly connected to one side of the positioning pile 1, the threaded rod 7 is fixedly connected to one side of the connecting plate 6 and passes through the measuring pile 2, and the fixing nut 8 is threadedly connected to one end of the threaded rod 7 and fits against one side of the measuring pile 2. A guide groove 9 is provided on the side of the measuring pile 2 along the length direction of the measuring pile 2, and the threaded rod 7 slides within the guide groove 9 to adjust the relative height between the positioning pile 1 and the measuring pile 2.

[0030] The threaded rod 7 can move within the guide groove 9. While sliding, it changes the relative height between the measuring stake 2 and the positioning stake 1. After tightening the fixing nut 8, the fixing nut 8 will press against one side of the measuring stake 2, and the connecting plate 6 will press against the other side of the measuring stake 2, thereby fixing the position of the measuring stake 2 and preventing it from moving. By adjusting the height of different measuring stakes 2 and positioning stakes 1, multiple measuring stakes 2 can be adjusted to the same zero mark, making it more convenient and faster to check the scale during backfilling.

[0031] In this embodiment, as a preferred solution, the connecting mechanism includes a winding roller 10 and a connecting line 11. The winding roller 10 is rotatably disposed inside the storage box 5. The connecting line 11 is wound around the outer surface of the winding roller 10. One end of the connecting line 11 away from the winding roller 10 is connected to another measuring stake 2. A slot 12 is provided on one side of the slider 4. A buckle 13 adapted to the slot 12 is fixedly connected to the end of the connecting line 11 away from the winding roller 10. The buckle 13 is detachably connected to the slot 12. A turntable 14 is provided on one side of the storage box 5. One end of the turntable 14 is fixedly connected to the winding roller 10 through a connecting shaft to drive the winding roller 10 to rotate. A ratchet 15 is provided on the outer surface of the turntable 14. A pawl 16 is rotatably connected to the back of the storage box 5 through a torsion spring. The pawl 16 is adapted to the ratchet 15 to limit the rotation direction of the ratchet 15.

[0032] The winding roller 10 is placed inside the storage box 5. The connecting wire 11 is wound around the winding roller 10. After the connecting wire 11 is pulled out, the buckle 13 at one end of the connecting wire 11 can engage with the slot 12 of the slider 4 on another measuring post 2, thereby connecting two adjacent measuring posts 2 through the connecting wire 11. The turntable 14 outside the storage box 5 drives the winding roller 10 to rotate. By rotating the turntable 14, the winding roller 10 can be rotated, thereby retracting the externally wound connecting wire 11. The ratchet 15 outside the turntable 14 and the storage box 5 The pawl 16 on the upper part can control the rotation direction of the turntable 14, thereby controlling the rotation of the internal winding roller 10 to prevent the connecting wire 11 from falling outward due to gravity. When it is necessary to release the wire, the pawl 16 is moved to one side. At this time, the pawl 16 and the ratchet 15 are separated. The connecting wire 11 can be released by rotating the turntable 14. When it is necessary to store the wire, the turntable 14 is rotated directly. At this time, the ratchet 15 on the outside and the pawl 16 cannot be locked together. The turntable 14 can rotate smoothly. The connecting wire 11 can be stored in the storage box 5 by rotating the turntable 14.

[0033] In this embodiment, as a preferred option, the interior of the retaining wall 3 is filled with concrete 17 to fix the position of the positioning pile 1. The top of the retaining wall 3 is fixedly connected with a fence 18, and the lower surface of the positioning pile 1 is fixedly connected with a ground nail 20 to improve the stability of the positioning pile 1.

[0034] After the positioning pile 1 is inserted into the ground, it is initially positioned. After the position is determined, concrete 17 is poured inside the retaining wall 3 to firmly position the positioning pile 1 and prevent it from shaking during use. The ground nail 20 at the bottom of the positioning pile 1 can be inserted into the ground, which makes it more stable during the initial fixing and prevents the positioning pile 1 from shaking during the pouring process.

[0035] In this invention, the working steps of the device are as follows:

[0036] 1. Based on the required measurement location, insert the positioning stake 1 into the ground, use a level to adjust the height of the measuring stake 2, adjust the zero mark of multiple measuring stakes 2 to the same height, and after adjustment, tighten the fixing nut 8 to fix the height of the measuring stake 2.

[0037] 2. After fixing the measuring stake 2, build a retaining wall 3 around the measuring stake 2 and the positioning stake 1. After the wall is built, pour concrete 17 inside to firmly fix the position of the positioning stake 1.

[0038] 3. Based on the required backfill height, adjust the slider 4 to the corresponding height, pull the ratchet 15 to one side and rotate the turntable 14 to release the connecting line 11, connect the connecting line 11 on the current measuring stake 2 with the adjacent measuring stake 2, and connect the connecting line 11 on the other measuring stake 2 with the subsequent measuring stake 2 again. After the connection is completed, backfilling is carried out. During the backfilling process, check the height of the backfill soil to the control line until the backfill soil reaches the height of the control line.

[0039] 4. After backfilling one layer, if it is necessary to increase the height again, move slider 4 upward to the height of the second layer of backfill, adjust it, and then continue backfilling.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
