Description

Technical Field

[0001] This invention relates to the field of backfilling technology, and in particular to a digital construction monitoring system for hydraulic compactors used in backfilling. Background Technology

[0002] High embankment subgrades commonly suffer from poor stability, subgrade settlement, and slope collapse, especially in areas with significant topographic relief and abundant surface water systems, where stability, settlement, and slope problems are more pronounced. During construction, dynamic compaction must be strictly implemented according to design requirements to reduce post-construction settlement of high embankment subgrades. The traditional dynamic compaction method involves dropping a heavy hammer from a height to forcefully compact the soil. Its mechanism involves using significant impact energy to create large shock waves and stresses in the soil, thereby compressing voids, causing localized liquefaction, and rapid consolidation.

[0003] In the backfilling construction of bridge and culvert abutments, due to the limited working space, large compactors find it difficult to achieve all-round compaction. Using a hydraulic compactor, however, can achieve compaction without dead angles, reducing or avoiding interlayer slippage and separation that may occur during layered compaction. The working principle of a hydraulic compactor is as follows: a hydraulic cylinder lifts the hammer to a certain height and then releases it. Under the combined action of gravity and the hydraulic accumulator, the hammer accelerates its descent, impacting the ground with a cushioned foot. The foot then compacts the ground, achieving the desired compaction of the roadbed.

[0004] Traditional dynamic compaction and hydraulic compaction require manual layout, guidance, and recording during construction, resulting in low construction efficiency and inaccurate recording. Therefore, a digital construction monitoring system for hydraulic compaction used for backfilling of abutments is needed. Summary of the Invention

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Reference Figures 1-9 A digital construction monitoring system for hydraulic compactors used for backfilling of abutments includes a monitoring equipment mounting box 1. A fixing plate 2 with an arc-shaped end is fixedly connected to the lower surface of the monitoring equipment mounting box 1. The four fixing plates 2 are symmetrically distributed around the axis of the monitoring equipment mounting box 1.

[0043] The surface of the fixed plate 2 is rotatably connected to the axle 3 via bearings, and four drive wheels 4 for moving the monitoring equipment mounting box 1 are fixedly installed on the surface of the axle 3.

[0044] A push handle 5 for moving the monitoring equipment installation box 1 is fixedly connected to the surface of the monitoring equipment installation box 1.

[0045] The monitoring equipment installation box 1 is internally equipped with a digital monitoring mechanism for monitoring the hydraulic compactor construction of the backfilling platform and an auxiliary mechanism for monitoring and positioning during construction.

[0046] The digital monitoring unit includes a battery 6 for providing power to the monitoring unit, which is fixedly installed on the inner top wall of the monitoring equipment mounting box 1.

[0047] The monitoring equipment installation box 1 has a positioning module 601, an optical fiber sensor 602, a monitoring camera 603, and a wireless communication module 604 fixedly installed on its inner bottom wall and upper surface, respectively, which are electrically connected to the storage battery 6 via cables.

[0048] The positioning module 601, the fiber optic sensor 602, and the monitoring camera 603 are all electrically connected to the wireless communication module 604 via cables.

[0049] The wireless communication module 604 is connected to the digital construction remote monitoring platform 605 via network data communication.

[0050] Furthermore, the positioning module 601 is used to monitor the positioning of the hydraulic rammer during construction, and the fiber optic sensor 602 (DAS) is used to monitor the impact data of the hydraulic rammer.

[0051] Furthermore, the positioning module 601 adopts a GPS positioning module 601 or a Beidou positioning module 601.

[0052] Furthermore, during use, the distributed fiber optic acoustic wave sensing monitoring system is connected via fiber optic sensor 602. When monitoring the hydraulic tamping construction of the abutment backfill, the vibration generated by the hydraulic tamping is monitored, thereby enabling the monitoring of information such as the number of tamping blows, tamping energy, and tamping spacing. It also features high-precision vibration wave analysis capabilities and can reconstruct sound information events around the optical cable, accurately reproducing sound information from multiple channels without interference. The DAS monitoring system also has artificial intelligence analysis capabilities. In the audio analysis section, it can automatically filter interference signals from pre-set whitelisted events, such as passing vehicles, wind, rain, and lightning, thus achieving better monitoring results for the hydraulic tamping construction of the abutment backfill.

[0053] Furthermore, the monitoring camera 603 is used to conduct video recording and monitoring of the construction site for the hydraulic compaction of the backfill.

[0054] Furthermore, the wireless communication module 604 is used to feed back the positioning information of the positioning module 601, the impact data information monitored by the fiber optic sensor 602, and the video monitoring information of the monitoring camera 603 to the digital construction remote monitoring platform 605.

[0055] The construction monitoring and positioning auxiliary mechanism includes an optical fiber winding wheel 7 for winding up the optical fiber cable of the optical fiber sensor 602, which is installed inside the monitoring equipment installation box 1.

[0056] The bottom wall of the monitoring equipment installation box 1 is fixedly connected with a winding support column 701, and the two winding support columns 701 are symmetrically distributed with the axis of the fiber optic winding wheel 7 as the center.

[0057] Both ends of the fiber optic take-up wheel 7 are rotatably connected to the surfaces of the two take-up support columns 701 via bearings.

[0058] At both ends of the fiber optic take-up wheel 7, a first sprocket 702 and a driven pulley 703 are fixedly installed and slidably connected to the surface of the take-up support column 701, respectively. At one end of one of the wheel shafts 3, a driving pulley 704 is fixedly installed, and the driving pulley 704 is connected to the driven pulley 703 by a belt.

[0059] In use, the drive wheel 4 drives the monitoring equipment mounting box 1 to move. When the drive wheel 4 rotates, it drives the wheel shaft 3 to rotate, which in turn drives the drive pulley 704 to rotate. The drive pulley 704 drives the driven pulley 703 to rotate via the belt, which in turn drives the optical fiber winding wheel 7 to rotate, thereby winding and unwinding the optical fiber cable.

[0060] Furthermore, the axle 3 drives the optical fiber take-up wheel 7 to rotate via the drive pulley 704, the driven pulley 703, and the belt. This not only achieves the effect of the drive wheel 4 rotating to drive the optical fiber take-up wheel 7 to rotate, but also, during the winding and unwinding process, if the optical fiber cable is over-unwound or over-wound, the increased resistance between the belt and the drive pulley 704 and the driven pulley 703 causes the belt to slip, preventing the optical fiber take-up wheel 7 from always following the drive wheel 4 to rotate, thus avoiding over-unwound or over-wound of the optical fiber cable. It also ensures that the optical fiber take-up wheel 7 is not limited by the speed of the drive wheel 4 when it is rapidly winding and unwinding.

[0061] One side of the fiber optic winding wheel 7 is provided with a wire support column 705 that is fixedly connected to the bottom wall of the monitoring equipment installation box 1. The two wire support columns 705 are symmetrically distributed with the axis of the fiber optic winding wheel 7 as the center.

[0062] The surface of the wire support column 705 is rotatably connected to the wire roller 706 via a bearing, and the surface of the wire roller 706 is provided with a double helical wire groove 707.

[0063] One end of the guide roller 706 extends to the surface of the guide support column 705, and a second sprocket 708 is fixedly installed on one end of the guide roller 706. The second sprocket 708 is connected to the first sprocket 702 via a chain.

[0064] The monitoring equipment installation box 1 has a wire slide rail seat 709 with a convex inner wall fixedly connected to its inner bottom wall. A wire slider 710 is slidably connected to the inner wall of the wire slide rail seat 709. One end of the wire slider 710 extends to the upper surface of the wire slide rail seat 709. A wire hole 711 is opened on the surface of the wire slider 710.

[0065] A wire drive block 712 is fixedly connected to the surface of the wire slider 710, and the surface of the wire drive block 712 is slidably connected to the inner wall of the double helix wire groove 707.

[0066] When in use, the optical fiber take-up wheel 7 rotates, driving the first sprocket 702 to rotate. The first sprocket 702 drives the second sprocket 708 to rotate via a chain, which in turn drives the conductor roller 706 to rotate. The conductor roller 706 drives the conductor drive block 712 to reciprocate via the double helical conductor groove 707, which in turn drives the conductor slider 710 to reciprocate, and drives the conductor hole 711 to reciprocate. This ensures that the optical fiber cable is evenly wound and unwound on the surface of the optical fiber take-up wheel 7 during the winding and unwinding of the optical fiber cable.

[0067] A controller 713 is fixedly installed on the inner bottom wall of the monitoring equipment installation box 1. The controller 713 is electrically connected to the wireless communication module 604 via a cable. A drive motor 714 is fixedly installed on the surface of one of the wire support columns 705. The drive motor 714 is electrically connected to the controller 713 via a cable. The output shaft of the drive motor 714 is fixedly connected to the other end of the wire roller 706 via a coupling.

[0068] In use, the controller 713 automatically controls the drive motor 714 to work. When it is necessary to quickly wind and unwind the optical fiber cable, the output shaft of the drive motor 714 drives the guide roller 706 to rotate quickly through the coupling. The guide roller 706 drives the first sprocket 702 to rotate quickly through the second sprocket 708, which in turn drives the optical fiber winding wheel 7 to rotate quickly for rapid winding and unwinding.

[0069] A tensioning cylinder 715 is provided on one side of the guide roller 706. The tensioning cylinder 715 is electrically connected to the controller 713 through a solenoid valve and a pressure sensor.

[0070] In use, the tensioning cylinder 715 is connected to the controller 713 via a solenoid valve and a pressure sensor. This allows the controller 713 to automatically control the opening and closing of the solenoid valve and control the tensioning cylinder 715 to perform telescopic movements.

[0071] The tensioning cylinder 715 includes a tensioning rod 716, one end of which is fixedly mounted with a tensioning wheel 717. A center positioning wheel 718 is fixedly mounted on the inner wall of the monitoring equipment mounting box 1. The two center positioning wheels 718 are symmetrically distributed around the axis of the tensioning cylinder 715, and the axes of the center positioning wheel 718 and the tensioning wheel 717 are on the same horizontal line.

[0072] During use, the tensioning wheel 717 provides tension to the optical fiber cable. When the optical fiber cable is wound up and unwound, the pressure inside the tensioning cylinder 715 decreases. The pressure sensor feeds back the pressure information to the controller 713. The controller 713 controls the tensioning rod 716 inside the tensioning cylinder 715 to extend, driving the tensioning wheel 717 to move upward, ensuring that the optical fiber cable maintains a certain tension. At the same time, when the optical fiber cable is still loose after the tensioning rod 716 has extended more than two-thirds of its stroke, the controller 713 automatically controls the drive motor 714 to work. The output shaft of the drive motor 714 drives the guide roller 706 to rotate in the opposite direction to the optical fiber winding wheel 7, tightening the optical fiber cable.

[0073] When the fiber optic cable is wound or unwound too tightly, resulting in excessive tension and excessive pressure on the tensioning cylinder 715, the controller 713 controls the tensioning rod 716 to retract into the tensioning cylinder 715, reducing the tension on the fiber optic cable. Simultaneously, if the pressure remains excessive even after the tensioning rod 716 has entered the tensioning cylinder 715 more than two-thirds of its travel, the controller 713 automatically controls the drive motor 714 to rotate in the same direction as the fiber optic winding wheel 7, thus loosening the fiber optic cable.

[0074] A measuring mounting plate 719 is fixedly connected to the inner bottom wall of the monitoring equipment mounting box 1. The two measuring mounting plates 719 are symmetrically distributed around the axis of the central positioning wheel 718. The surface of the measuring mounting plate 719 is rotatably connected to the pressure wheel 720 and the measuring wheel 721 respectively through bearings. One end of the measuring wheel 721 extends to the surface of the measuring mounting plate 719. A rotary encoder 722 is fixedly installed on the surface of the measuring mounting plate 719 and fixedly connected to one end of the measuring wheel 721. The rotary encoder 722 is electrically connected to the controller 713 through a cable.

[0075] In use, the measuring wheel 721 rotates to follow the fiber optic cable during winding and unwinding. The rotary encoder 722 monitors the number of rotations of the measuring wheel 721 and feeds the data back to the controller 713, thereby monitoring the length of the fiber optic cable during winding and unwinding. This enables rapid positioning and recording of the vibration waves detected in the fiber optic cable, achieving more accurate monitoring and recording of the compaction data during backfilling and compaction construction.

[0076] The surface of the monitoring equipment installation box 1 is provided with a take-up and release groove 723 that communicates with the inner wall of the monitoring equipment installation box 1. The inner wall of the take-up and release groove 723 is rotatably connected to the take-up and release roller 724. A counterweight positioning block 725 is inserted into the inner wall of the take-up and release groove 723 and fixedly connected to one end of the optical fiber cable.

[0077] By setting up a construction monitoring and positioning auxiliary mechanism, during use, the drive wheel 4 rotates during the movement of the monitoring equipment installation box 1, which in turn drives the wheel axle 3 to rotate, which in turn drives the active pulley 704 to rotate. The active pulley 704 drives the driven pulley 703 to rotate via a belt, which in turn drives the optical fiber winding wheel 7 to rotate, thereby monitoring the laying of the optical fiber cable. During the laying process, the length of the laid cable is monitored and calculated by the rotary encoder 722, and the tension cylinder 715 and the drive motor 714 are automatically controlled by the controller 713 to ensure that the laid optical fiber cable remains straight.

[0078] By setting up a digital monitoring mechanism and a construction monitoring and positioning auxiliary mechanism, during the digital monitoring of hydraulic compaction construction for backfilling of the abutment, the positioning module 601 locates the construction position, the monitoring camera 603 monitors the compaction construction via video, and the fiber optic sensor 602 monitors the vibration generated by the hydraulic compaction. This enables digital construction monitoring of the number of compactions, compaction energy, and compaction spacing during backfilling compaction construction, and feeds the information back to the digital remote monitoring platform via the wireless communication module 604. This solves the problems of low construction efficiency and inaccurate recording in the existing hydraulic compaction construction process, which requires manual line setting, guidance, and recording.

[0079] Working principle: During use, at the hydraulic compaction construction site for backfilling, the counterweight positioning block 725 is placed at one end of the construction site. Then, the monitoring equipment installation box 1 is moved by the push handle 5. During the movement of the monitoring equipment installation box 1, the drive wheel 4 rotates, which drives the wheel axle 3 to rotate, which in turn drives the drive pulley 704 to rotate. The drive pulley 704 drives the driven pulley 703 to rotate via the belt, which in turn drives the fiber optic winding wheel 7 to rotate, thus monitoring the laying of the fiber optic cable. During the laying process, the length of the laid cable is monitored and calculated by the rotary encoder 722, and the tension cylinder 715 and drive motor 714 are automatically controlled by the controller 713 to ensure that the laid fiber optic cable remains straight. After the laying is completed, the monitoring equipment installation box 1 is positioned and fixed, and then the positioning information of the positioning module 601 is fed back to the digital remote monitoring platform through the wireless communication module 604.

[0080] During the hydraulic compaction construction of the abutment backfill, the monitoring camera 603 and the wireless communication module 604 are used to monitor the hydraulic compaction construction site via video. Then, the fiber optic sensor 602 is connected to the distributed fiber optic acoustic wave sensing and monitoring system. When monitoring the hydraulic compaction construction of the abutment backfill, the vibration generated by the hydraulic compaction is monitored to realize digital construction monitoring of information such as the number of compactions, compaction energy and compaction spacing.
