Description

Technical Field

[0001] This utility model belongs to the field of on-site monitoring technology in civil engineering, and more specifically, it relates to a deformation monitoring device for filled soil foundations containing vertical reinforcement. Background Technology

[0002] For filled soil foundations, soil deformation monitoring can verify the quality of the filling construction and invert soil deformation parameters, providing a basis for predicting subsequent foundation deformation. Currently, commonly used methods for monitoring filled soil deformation in engineering mainly include the settlement plate method and the settlement tube method.

[0003] The settlement plate method involves embedding a metal base plate in the fill and connecting it to the ground surface via vertical rods to measure elevation changes. While intuitive, this method has significant drawbacks in practical applications: First, the vertical rods penetrate the fill layer, severely interfering with the compaction of the surrounding soil, leading to insufficient compaction of the soil around the plate, affecting the uniformity of the foundation and introducing measurement errors; second, the exposed vertical rods are easily impacted, bent, or even damaged by the reciprocating operation of large machinery (such as road rollers and bulldozers), resulting in poor reliability and durability.

[0004] The settlement tube method involves pre-burying flexible inclinometer tubes and using an inclinometer to detect the deformation of the tubes in order to calculate soil displacement. However, this method is cumbersome to install and requires extremely high precision in the connection and verticality of the guide tubes. More importantly, when uneven settlement of the backfill causes excessive curvature of the observation profile, the inclinometer probe cannot pass through smoothly, resulting in interruption of the observation work and the inability to obtain complete deformation data.

[0005] In summary, existing commonly used observation methods either interfere with construction due to their own structure and are easily damaged, or are difficult to work continuously and effectively due to poor adaptability to foundation deformation. Utility Model Content

[0006] This utility model provides a soil foundation deformation monitoring device with vertical reinforcement. Taking advantage of the fact that some foundation treatment projects require the excavation of some backfill soil after backfilling, the displacement box is buried at the later excavation location. On the one hand, it can effectively protect the displacement box, and on the other hand, it can eliminate the interference of displacement monitoring on construction.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a deformation monitoring device for backfill foundation with vertical reinforcement is provided, including a displacement box, measuring lines, a support component, and an auxiliary measuring component. The displacement box is buried in the backfill and includes a box body with an upward opening and a cover for sealing the opening of the box body. The measuring lines are set inside the displacement box and connected to the box body and the cover at both ends respectively. The support component is set above the backfill and is arranged vertically and vertically corresponding to the displacement box. The auxiliary measuring component is set on the top of the support component and has a through hole for the measuring lines to pass through along the vertical direction.

[0008] In one possible implementation, the inner top wall of the cover is provided with a fixing member for fixing the upper end of the test line. The fixing member includes a fixing cylinder and a fixing bolt. The fixing cylinder is connected to the inner top wall of the cover and extends downward to accommodate the upper end of the test line. The fixing bolt is threaded into the fixing cylinder to press and fix the upper end of the test line.

[0009] In some embodiments, a fixing hole is provided through the outer peripheral wall of the fixing cylinder for the end of the measuring line to pass through.

[0010] In some embodiments, there are several measuring lines and several fixing members, with each measuring line corresponding to one of the fixing members.

[0011] In one possible implementation, the displacement box is equipped with a lifting rope, with its two ends connected to the box body and the cover, respectively. The lifting rope is used to lift the box body upwards.

[0012] In some embodiments, the inner bottom wall of the box is provided with a first fixing lug for connecting the lower end of the suspension rope and the lower end of the measuring line.

[0013] In some embodiments, the inner top wall of the cover is provided with a second fixing lug for the upper end of the suspension rope to be connected.

[0014] In one possible implementation, the support includes a tray, a spirit level, and several support legs. The tray has a through hole running vertically through it. The spirit level is located at the top of the tray. The several support legs are located at the bottom of the tray and are spaced apart in the circumferential direction of the tray, with the support legs extending outward and downward.

[0015] In one possible implementation, the bottom of the auxiliary measuring component is provided with a guide plate located on one side of the wire hole and extending downward, which is used to contact and cooperate with the measuring line to adjust the perpendicularity of the measuring line.

[0016] In one possible implementation, the displacement box is covered with a flexible protective cover.

[0017] The soil filling foundation deformation monitoring device with vertical reinforcement provided in this embodiment has the following advantages compared with the prior art: The displacement cell is completely buried underground, and there are no obstacles on the ground surface during backfilling, completely avoiding interference with the backfilling operation and ensuring the quality of soil compaction; the bottom displacement is calculated by measuring the coordinates of the top of the straightened measuring line, and the principle is clear. The support components and auxiliary measuring components erected during measurement provide a stable and accurate temporary reference point; the main measuring components (displacement cell, measuring line) are buried underground during non-measuring periods, avoiding direct crushing and collision by construction machinery, thus receiving effective protection, being reusable, and having a longer service life.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] For filled soil foundations, soil deformation can reflect the quality of the filling construction and can be used to infer soil deformation parameters, providing a basis for predicting subsequent foundation deformation. Currently, commonly used methods for monitoring filled soil deformation in engineering mainly include the settlement plate method and the settlement tube method.

[0024] The settlement plate method involves embedding a metal base plate in the fill and connecting it to the ground surface via vertical rods to measure elevation changes. While intuitive, this method has significant drawbacks in practical applications: First, the vertical rods penetrate the fill layer, severely interfering with the compaction of the surrounding soil, leading to insufficient compaction of the soil around the plate, affecting the uniformity of the foundation and introducing measurement errors; second, the exposed vertical rods are easily impacted, bent, or even damaged by the reciprocating operation of large machinery (such as road rollers and bulldozers), resulting in poor reliability and durability.

[0025] The settlement tube method involves pre-burying flexible inclinometer tubes and using an inclinometer to detect the deformation of the tubes in order to calculate soil displacement. However, this method is cumbersome to install and requires extremely high precision in the connection and verticality of the guide tubes. More importantly, when uneven settlement of the backfill causes excessive curvature of the observation profile, the inclinometer probe cannot pass through smoothly, resulting in interruption of the observation work and the inability to obtain complete deformation data.

[0026] In summary, existing commonly used observation methods either interfere with construction due to their own structure and are easily damaged, or are difficult to work continuously and effectively due to poor adaptability to foundation deformation.

[0027] In some foundation treatment projects, after the backfill is completed, it is necessary to excavate part of the soil in the backfill and then construct vertical reinforcements such as lime-soil piles. Taking advantage of the characteristic that part of the backfill needs to be excavated after the backfill is completed, this application develops a backfill foundation deformation monitoring device containing vertical reinforcements.

[0028] Please see Figures 1 to 7 The present invention provides a method for monitoring the deformation of a backfill foundation with vertical reinforcement. The method includes a displacement box 10, a measuring line 20, a support member 30, and an auxiliary measuring member 40. The displacement box 10 is embedded in the backfill 1 and includes an upward-opening box body 11 and a cover 12 for sealing the opening of the box body 11. The measuring line 20 is disposed inside the displacement box 10 and its two ends are connected to the box body 11 and the cover 12, respectively. The support member 30 is disposed above the backfill 1 and is vertically corresponding to the displacement box 10. The auxiliary measuring member 40 is disposed on the top of the support member 30, and a through hole 41 for the measuring line 20 to pass through is provided on the auxiliary measuring member 40 along the vertical direction.

[0029] Furthermore, the measuring line 20 is inelastic and has graduated lines.

[0030] Furthermore, there are three threading holes 41 arranged in an equilateral triangle.

[0031] Furthermore, since the diameter of the threading hole 41 is relatively small, the opening of the threading hole 41 is considered as one point during measurement.

[0032] This application provides a soil foundation deformation monitoring device with vertical reinforcement. In its actual use, before installation, the displacement box 10 is placed in a preset position (the outside of the displacement box 10 is covered with non-woven fabric or other materials for easy removal later). A support member 30 is erected above the displacement box 10 to ensure the auxiliary measuring member 40 is horizontal. The cover 12 is opened and moved upwards above the displacement box 10. The upper end of the measuring line 20, originally fixed to the cover 12, is detached and passed through the auxiliary measuring member 40 from bottom to top. With the wire hole 41 in place and the measuring line 20 in a vertical and taut state, use a total station or other measuring instruments to measure the plane coordinates (A1, B1) of the center of the wire hole 41. Read the scale L1 at the opening of the wire hole 41 on the measuring line 20. Read the scale L0 at the opening of the first fixed lug 111 connecting to the positioning hole 112 (the hole diameter is small and can be regarded as 1 point during measurement). Place a miniature leveling rod on the upper surface of the auxiliary measuring piece 40 and use a level to measure the elevation H1 of the opening of the first fixed lug 111 connecting to the positioning hole 112. H1 = P1 - (L1 - L0 + T1), where P1 is the elevation of point C, the center of the leveling instrument's telescope, and T1 is the corresponding reading of the miniature leveling rod in the crosshairs of the leveling instrument's telescope.

[0033] Store the support component 30 and the auxiliary measuring component 40, and continue the backfilling operation. After the backfilling is completed, drill a hole directly above the displacement box 10 until the cover 12 of the displacement box 10 is exposed; Set up the support 30 and auxiliary measuring component 40 again above the borehole, ensuring that the auxiliary measuring component 40 is in a horizontal state; open and move the cover 12 up to the top of the borehole, remove the upper end of the measuring line 20 that was originally fixed on the cover 12, and let it pass through the threading hole 41 on the auxiliary measuring component 40 from bottom to top, keeping the measuring line 20 in a vertical and taut state, use a total station or other measuring instruments to measure the coordinates (A2, B2) of the center of the threading hole 41, read the scale L2 of the measuring line 20 at the opening of the threading hole 41, place a miniature leveling rod on the upper surface of the auxiliary measuring component 40, and use a level to measure the elevation H2 of the opening of the first fixed lug 111 connected to the positioning hole 112; H2 = P2 - (L2 - L0 + T2), where P2 is the elevation of point C, the center of the leveling instrument's telescope, and T2 is the corresponding reading of the miniature leveling rod in the crosshairs of the leveling instrument's telescope.

[0034] The horizontal displacement (△A, △B) of displacement box 10 (i.e., the foundation at this location) during the backfilling process can be calculated using coordinates (A1, B1) and (A2, B2); the settlement △H can be calculated using H1 and H2.

[0035] For example, if (A1,B1) = (30.135, 44.561) and (A2,B2) = (30.138, 44.563), then (△A,△B) = (A2,B2) - (A1,B1) = (0.003, 0.002). For example, the measured value is H1 = P1 - (L1 - L0 + T1) = 63.332 - (1.112 - 0.010 + 0.121) = 62.109; H2=P2-(L2-L0+T2)=68.409-(6.223-0.010+0.130)=62.066; Then △H = H1 - H2 = 62.109 - 62.066 = 0.043.

[0036] The soil filling foundation deformation monitoring device with vertical reinforcement provided in this embodiment, compared with the prior art, completely buries the displacement box 10 underground, eliminating any obstacles on the ground surface during backfilling and compaction, thus completely avoiding interference with the backfilling and compaction operations and ensuring the compaction quality of the fill 1. The bottom displacement is calculated by measuring the coordinates of the top of the straightened measuring line 20, and the principle is clear. The support 30 and auxiliary measuring components 40 erected during measurement provide a stable and accurate temporary reference point. The main measuring components (displacement box 10 and measuring line 20) are buried underground during non-measuring periods, avoiding direct rolling and collision by construction machinery, thus being effectively protected, reusable, and having a longer service life.

[0037] In one possible implementation, the aforementioned cap 12 adopts the following... Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3 The inner top wall of the cover 12 is provided with a fixing member 50 for fixing the upper end of the measuring line 20. The fixing member 50 includes a fixing cylinder 51 and a fixing bolt 52. The fixing cylinder 51 is connected to the inner top wall of the cover 12 and extends downward to accommodate the upper end of the measuring line 20. The fixing bolt 52 is threaded into the fixing cylinder 51 to press and fix the upper end of the measuring line 20.

[0038] Specifically, before the upper end of the measuring line 20 is passed through the wire hole 41, or during installation, its end is inserted into the cylinder from the lower port of the fixing cylinder 51, and then the fixing bolt 52 is tightened to fix the measuring line 20 by the compression of the bolt.

[0039] The bolts provide strong mechanical gripping force, ensuring that the measuring line 20 will not slip when subjected to tension, thus guaranteeing the stability of subsequent measurements.

[0040] In some embodiments, see Figure 3 The outer peripheral wall of the fixed cylinder 51 is provided with a fixing hole 53 for the end of the measuring line 20 to pass through.

[0041] Specifically, before the upper end of the measuring line 20 passes through the wire hole 41, or during installation, its end is inserted into the cylinder through the fixing hole 53 on the side wall of the fixing cylinder 51, and then the fixing bolt 52 is tightened. The end of the bolt is used to squeeze and fix the measuring line 20, thus avoiding direct screw thread squeezing and damage to the measuring line 20.

[0042] In some embodiments, see Figures 1 to 3 There are several measuring lines 20 and several fixing parts 50, and the several measuring lines 20 and several fixing parts 50 are set in a one-to-one correspondence.

[0043] Specifically, multiple measuring lines 20 are set inside the displacement box 10. Each measuring line 20 is independently connected to the box body 11 and the cover 12, and corresponds to an independent fixing component 50. During measurement, each measuring line 20 can be led and its coordinates measured sequentially or selectively.

[0044] By averaging multiple independent measurement results, the random error of a single measurement can be effectively reduced, making the final displacement data more accurate and reliable.

[0045] When one or more measuring lines 20 are damaged due to an accident, the remaining measuring lines 20 can still continue to work, which greatly enhances the reliability of the entire monitoring system.

[0046] In one possible implementation, the displacement box 10 described above adopts the following... Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3 The displacement box 10 is equipped with a lifting rope 60. The two ends of the lifting rope 60 are connected to the box body 11 and the cover 12 respectively. The lifting rope 60 is used to lift the box body 11 upward.

[0047] Specifically, after locating the displacement box 10 through drilling, the cover 12 is lifted to separate the measuring line 20 from the cover 12. After the measurement is completed, the lifting rope 60 is lifted to pull the box body 11 below upwards together, so that the entire displacement box 10 can be taken out, which improves the convenience of taking out the displacement box 10 and facilitates its reuse next time.

[0048] In some embodiments, see Figure 1 The inner bottom wall of the box 11 is provided with a first fixing ear 111 for connecting the lower end of the suspension rope 60 and the lower end of the measuring line 20.

[0049] Specifically, during the installation phase, the lower ends of the suspension rope 60 and the measuring line 20 are connected together or separately to the first fixing lug 111 on the bottom wall of the box 11, providing a standard and secure connection point. This concentrates and clarifies the force on the suspension rope 60 and the measuring line 20, improving the reliability of the connection.

[0050] Furthermore, there are several first fixing ears 111, and the suspension rope 60 and the measuring line 20 are respectively connected to the corresponding first fixing ears 111.

[0051] Furthermore, such as Figure 7 As shown, the first fixing ear 111 has a connecting positioning hole 112 extending through it in the vertical direction for the lower end of the measuring line 20 to pass through. The first fixing ear 111, which is only connected to the measuring line 20, has the connecting positioning hole 112 to prevent the lower end of the measuring line 20 from sliding on the first fixing ear 111 and to eliminate measurement errors. The lower end of the measuring line 20 passes through the connecting positioning hole 112 and is connected to the first fixing ear 111.

[0052] In some embodiments, see Figures 1 to 3 The inner top wall of the cover 12 is provided with a second fixing lug 121 for the upper end of the suspension rope 60 to be connected.

[0053] Specifically, during the installation phase, the upper end of the lifting rope 60 is connected to the second fixing ear 121 on the inner top wall of the cover 12, providing a direct top suspension point for the lifting rope 60. When the cover 12 is lifted above the drill hole, the workers can directly grab the lifting rope 60 and pull up the box body 11.

[0054] In one possible implementation, the aforementioned support member 30 adopts, as shown in... Figure 1 and Figure 6 The structure shown is described in the following document. Figure 1 and Figure 6The support member 30 includes a support plate 31, a spirit level 33, and several support legs 34. The support plate 31 has a through hole 32 extending through it in the vertical direction. The spirit level 33 is located at the top of the support plate 31. Several support legs 34 are located at the bottom of the support plate 31 and are spaced apart in the circumferential direction of the support plate 31. The support legs 34 extend outward and downward.

[0055] Specifically, several support legs 34 are set up on the ground around the borehole to form a stable support. Then, the support plate 31 is placed on the support legs 34, and the height of each support leg 34 or the pad is adjusted by observing the level bubble 33 at the top of the support plate 31 to make the support plate 31 reach a precise level.

[0056] The triangular or multi-point support structure ensures the overall stability of the support frame, while the level bubble 33 ensures the levelness of the plane of the support plate 31, thus providing an accurate and reliable temporary reference surface for coordinate measurement.

[0057] In one possible implementation, the aforementioned auxiliary measuring element 40 adopts, as shown in... Figure 1 and Figure 4 The structure shown is described in the following document. Figure 1 and Figure 4 The bottom of the auxiliary measuring component 40 is provided with a guide plate 70 located on one side of the wire hole 41 and extending downward, which is used to contact and cooperate with the measuring line 20 to adjust the verticality of the measuring line 20.

[0058] Specifically, after passing the measuring line 20 through the threading hole 41, observe the fit between the measuring line 20 and the vertical side of the guide plate 70. If the measuring line 20 is tightly attached to the guide plate 70, its verticality is good; if there is a gap, the horizontal position of the auxiliary measuring component 40 on the support component 30 needs to be adjusted until the measuring line 20 is tightly attached to the guide plate 70. This provides an intuitive and real-time verticality calibration tool, ensuring that the measuring line 20 is truly vertical during measurement. This is crucial for accurately calculating the horizontal displacement and effectively avoids calculation errors caused by the tilt of the measuring line 20.

[0059] Furthermore, the upper and lower surfaces of the auxiliary measuring component 40 are flat, ensuring that the auxiliary measuring component 40 can slide horizontally on the support plate 31, and the upper surface of the auxiliary measuring component 40 is flat, ensuring that the miniature measuring rod placed on the upper surface of the auxiliary measuring component 40 is vertical during measurement.

[0060] In one possible implementation, the displacement box 10 described above adopts the following... Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3 The displacement box 10 is covered with a flexible protective cover 80.

[0061] Specifically, after placing the displacement box 10 in the predetermined position and before starting the backfilling 1, a flexible protective cover 80 (such as a thick rubber sleeve) is first placed over the entire displacement box 10. When drilling vertically to locate the displacement box 10, the flexible protective cover can buffer and disperse the impact force of the drill bit, preventing the drill bit from directly contacting and damaging the hard surface of the displacement box 10, thus protecting the displacement box 10.

[0062] Furthermore, both the top of the cover 12 and the flexible protective cover 80 are equipped with lifting lugs for external tools to be hooked.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
