Description

Technical Field

[0001] This invention relates to the field of road construction technology, specifically to a stabilizing and noise-reducing construction device and its construction method for civil engineering road projects. Background Technology

[0002] In recent years, with the continuous development of urbanization, urban environmental issues have gradually become the focus of people's attention. While urban road construction has alleviated urban traffic conflicts and reduced traffic pressure, the noise generated during road construction has also brought serious noise pollution to the surrounding areas, affecting the normal life of residents in the surrounding areas of urban roads.

[0003] A Chinese utility model patent application with application number 202020673763.3 discloses a noise reduction device for road construction, which includes a soundproof frame. Inside the soundproof frame, there are soundproof blocks, a cavity, fine sand, a rubber filling layer, and a sound-absorbing cotton board arranged in sequence. Support covers are connected to the two sides of the lower part of the soundproof frame. A moving device is provided inside the support cover. The moving device includes an electric telescopic rod and a universal wheel connected to each other. The electric telescopic rod is connected to a control button on the outside of the support cover. The above-mentioned noise reduction device is relatively easy to move and disassemble, and has a certain sound insulation effect. However, in actual use, the device is relatively cumbersome to operate and troublesome to assemble. Moreover, when the road is being constructed using a pneumatic hammer, the noise is generated simultaneously by mechanical impact and ground vibration, and the device cannot effectively isolate it.

[0004] Therefore, it is essential to design a practical and effective noise reduction construction device and its construction method for civil engineering road construction. Summary of the Invention

[0005] The purpose of this invention is to provide a stable and noise-reducing construction device and its construction method for civil engineering road construction, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a construction device for stabilizing and reducing noise in civil engineering road projects, comprising a soundproof cover, an insertion interface on the left side of the outer wall of the soundproof cover, and a connecting plate fixedly connected to the right side of the soundproof cover. The outer wall shape of the connecting plate is consistent with the inner wall shape of the insertion interface, and the positions of the insertion interface and the connecting plate on the soundproof cover are correspondingly arranged. A sealing plate is provided on both the left and right sides of the soundproof cover, and the outer wall of the sealing plate contacts the outer wall of the soundproof cover. A bolt connecting plate is fixedly connected to the upper side of the sealing plate, and one side of the bolt connecting plate extends to the upper side of the soundproof cover. The outer wall of the bolt connecting plate is fixedly connected to the outer wall of the soundproof cover by bolts. A lifting mechanism is fixedly connected to the inner wall of the soundproof cover, and a shock-absorbing mechanism is provided on the outside of the soundproof cover.

[0007] According to the above technical solution, the lifting mechanism includes a fixed pile, the outer wall of the fixed pile is fixedly connected to the inner wall of the soundproof cover, a hydraulic cylinder is fixedly connected to the inner wall of the fixed pile, a connecting plate is fixedly connected to the lower end of the hydraulic cylinder, a fixed plate is fixedly connected to the outer wall of the connecting plate near the soundproof cover, the outer wall of the fixed plate is slidably connected to the inner wall of the soundproof cover, and a roller is rotatably connected to the outer wall of the fixed plate through a bearing.

[0008] According to the above technical solution, the shock absorption mechanism includes a connecting piece, the outer wall of the connecting piece is fixedly connected to the outer wall of the soundproof cover by bolts, a connecting shell is fixedly connected to the outer wall of the connecting piece, a water bag is fixedly connected to the lower side of the connecting shell, a humidification mechanism is provided on the water bag, a water inlet pipe is fixedly connected to the side wall of the connecting piece, the water inlet pipe connects the inside and outside of the connecting piece, and a cap is threaded to one end of the water inlet pipe.

[0009] According to the above technical solution, the connecting shell and the water bag are wrapped in a strip around the outside of the soundproof cover, and the distance from the lower side of the connecting shell to the lower side of the soundproof cover is less than the difference between the outer diameter and the inner diameter of the water bag. Both the connecting shell and the water bag are made of rubber, and the hardness of the connecting shell is greater than that of the water bag.

[0010] According to the above technical solution, the humidification mechanism includes a fixed base, the outer wall of which is fixedly connected to the upper side of the outer wall of the water bag. A connecting frame is fixedly connected to the upper side of the fixed base, and a motor is fixedly connected to the inner wall of the connecting frame. Circular holes are provided on both the upper and lower sides of the water bag. An upper fixing tube is fixedly connected to the inner wall of the circular hole on the upper side of the water bag. The upper and lower ends of the upper fixing tube are located on the upper side and inside the water bag, respectively. The upper end of the upper fixing tube is fixedly connected to the lower side of the outer wall of the fixed base. The output end of the motor extends through the upper fixing tube to the lower side of the upper fixing tube. The output end of the motor is rotatably connected to the inner wall of the upper fixing tube via a bearing. A rotating rod is fixedly connected to the lower side of the output end of the motor. The outer wall of the rotating rod is a hexagonal prism. The structure includes a rotating block fitted on the outer wall of the rotating rod, a lower fixing tube threadedly connected to the outer wall of the rotating block, the upper side of the lower fixing tube fixedly connected to the lower outer wall of the upper fixing tube, the lower outer wall of the lower fixing tube fixedly connected to the inner wall of the circular hole on the lower side of the water bag, a connecting tube rotatably connected to the lower outer wall of the rotating block via a bearing, four lifting rods fixedly connected to the lower side of the connecting tube, the rotating rod being a hollow structure with an opening on the lower side, a water inlet hole in the middle of the rotating rod, an extension tube inserted into the lower inner wall of the rotating rod, the lower end of the extension tube extending to the outside of the rotating rod, a connecting rod fixedly connected to the outer wall of the extension tube, one end of the connecting rod fixedly connected to the lower outer wall of the connecting tube, and a nozzle rotatably connected to the lower side of the extension tube via a bearing.

[0011] According to the above technical solution, the rotating block can rotate synchronously with the rotating rod. When the rotating block rotates, it can drive the connecting pipe and the lifting rod to move downward. When the lifting rod moves downward, its lower end can extend to the lower side of the lower fixed pipe, and the water inlet is located on the upper side of the extension pipe.

[0012] According to the above technical solution, the diameter of the roller is greater than the vertical width of the fixed plate, and the lower side of the fixed plate is higher than the lower side of the roller. The extension and retraction stroke of the hydraulic cylinder is greater than the difference between the outer diameter and the inner diameter of the water bag.

[0013] A method for stabilizing and reducing noise in civil engineering road construction involves, before construction, detecting and protecting underground pipelines along the route to prevent unnecessary impacts on the project's progress. The project management team contacts the planning bureau to complete the handover of measurement control points and conducts re-measurements according to specifications. Simultaneously, a measurement control network is established to determine the road centerline and construction red line, and construction layout measurements are performed. Based on a thorough understanding of the design documents, the surveying and design unit conducts on-site measurement briefings, identifying site benchmarks, guide stakes, intersection stakes, etc., according to the design drawings, and recording stake handover. For measurement markers within the construction area, temporary facilities required for construction are promptly erected according to the overall construction plan and site conditions, paying attention to fire prevention, electrical leakage prevention, and other safety issues. At this time, several isolation devices are installed. The soundproof enclosures are spliced ​​together, with the connectors and connecting plates of adjacent enclosures interlocking to form a shield along the construction section. Note that the inner wall of the soundproof enclosure must be located on the outer side of the construction area. After the construction machinery enters the soundproof enclosure, lighting equipment is suspended on the upper inner surface to ensure sufficient illumination. Windows can be opened on the sealing plates according to actual soundproofing needs. If higher soundproofing is required, the sealing plates on both sides of the soundproof enclosure are fully fitted to the shielding sides formed by the enclosure. The sealing plates are then fixed to the soundproof enclosure with bolts. Water is supplied to the water bag and connecting shell through an external water supply device and inlet pipe, causing the water bag and connecting shell to expand and further adhere to the road surface. The machinery then proceeds with road construction inside the soundproof enclosure.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention, by setting up structures such as soundproof covers and sealing plates, completes the enclosure of construction machinery, so that the noise is reduced after being reduced by the soundproof covers and the noise has a reduced impact on the outside, thereby achieving the purpose of conveniently building a noise reduction area;

[0015] By incorporating a lifting mechanism, the noise reduction area of ​​this device can be adjusted at any time according to the construction progress, thereby enabling the device to move synchronously with the construction machinery and achieving the purpose of ease of use.

[0016] By incorporating a shock-absorbing mechanism, this device can reduce the vibrations caused by construction machinery impacts by using a water-filled bag that is in contact with the ground, thereby reducing the noise source and achieving the purpose of noise reduction.

[0017] By incorporating a humidification mechanism, water can be sprayed onto the ground below the fixed pipe through the nozzles, allowing the water to diffuse to the bottom of the water bag, thereby absorbing water and moistening the bottom surface. This reduces the vibration performance of the bottom surface and achieves the goal of reducing noise transmission. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7 The present invention provides a technical solution: a construction device for stabilizing and reducing noise in civil engineering road projects, including a soundproof cover 1. An insertion interface 2 is provided on the left side of the outer wall of the soundproof cover 1, and an insertion plate 3 is fixedly connected to the right side of the soundproof cover 1. The outer wall shape of the insertion plate 3 is consistent with the inner wall shape of the insertion interface 2, and the positions of the insertion interface 2 and the insertion plate 3 on the soundproof cover 1 are correspondingly set. A sealing plate 4 is provided on both the left and right sides of the soundproof cover 1. The outer wall of the sealing plate 4 contacts the outer wall of the soundproof cover 1. A bolt connecting plate 5 is fixedly connected to the upper side of the sealing plate 4. One side of the bolt connecting plate 5 extends to the upper side of the soundproof cover 1. The outer wall of the bolt connecting plate 5 is fixedly connected to the outer wall of the soundproof cover 1 by bolts. A lifting mechanism 6 is fixedly connected to the inner wall of the soundproof cover 1, and a shock absorption mechanism 7 is provided on the outside of the soundproof cover 1.

[0029] In use, several soundproof covers 1 in this device are spliced ​​together, so that the plug-in interfaces 2 and plug-in plates 3 of two adjacent soundproof covers 1 are spliced ​​together, so that the soundproof covers 1 form a shield along the construction section. Note that the inner wall of the soundproof cover 1 needs to be located on the outside of the construction area. After the construction machinery is driven into the interior of the soundproof cover 1, the lighting equipment is hung on the upper inner surface of the soundproof cover 1 to keep the interior of the soundproof cover 1 well lit. Windows can be opened on the sealing plate 4 according to the actual sound insulation needs. If the sound insulation requirements are high, the sealing plates 4 on both sides of the soundproof cover 1 are completely attached to the shield formed by the soundproof cover 1. Then the sealing plates 4 are fixed to the soundproof cover 1 with bolts. Since the interior of the soundproof cover 1 is equipped with 8 to achieve the sound insulation effect, the construction machinery can be soundproofed.

[0030] The lifting mechanism 6 includes a fixed pile 601, the outer wall of the fixed pile 601 is fixedly connected to the inner wall of the soundproof cover 1, a hydraulic cylinder 602 is fixedly connected to the inner wall of the fixed pile 601, a connecting plate 603 is fixedly connected to the lower end of the hydraulic cylinder 602, a fixed plate 604 is fixedly connected to the outer wall of the connecting plate 603 on the side close to the soundproof cover 1, the outer wall of the fixed plate 604 is slidably connected to the inner wall of the soundproof cover 1, and a roller 605 is rotatably connected to the outer wall of the fixed plate 604 through a bearing;

[0031] When in use, if the position of this device needs to be adjusted according to the construction progress, the hydraulic cylinder 602 can be activated to push the connecting plate 603 down, thereby causing the roller 605 to touch the ground. Then, the soundproof cover 1 in this device is lifted off the ground by the thrust of the hydraulic cylinder 602. Since the thrust stroke of the hydraulic cylinder 602 is relatively long, the shock absorption mechanism 7 is not in contact with the ground at this time. Then, it is moved by traction through the construction device to facilitate the movement. After the movement, the hydraulic cylinder 602 is retracted to make the device touch the ground again. The shock absorption mechanism 7 can be laid neatly by external construction personnel to achieve a better noise reduction effect.

[0032] The shock absorption mechanism 7 includes a connecting piece 701. The outer wall of the connecting piece 701 is fixedly connected to the outer wall of the soundproof cover 1 by bolts. A connecting shell 702 is fixedly connected to the outer wall of the connecting piece 701. A water bag 703 is fixedly connected to the lower side of the connecting shell 702. A humidification mechanism 704 is provided on the water bag 703. A water inlet pipe 705 is fixedly connected to the side wall of the connecting piece 701. The water inlet pipe 705 connects the inside and outside of the connecting piece 701. A cap 706 is threaded to one end of the water inlet pipe 705. The connecting shell 702 and the water bag 703 are wrapped around the outside of the soundproof cover 1 in a strip shape. The distance from the lower side of the connecting shell 702 to the lower side of the soundproof cover 1 is less than the difference between the outer diameter and the inner diameter of the water bag 703. Both the connecting shell 702 and the water bag 703 are made of rubber. The hardness of the connecting shell 702 is greater than that of the water bag 703.

[0033] When in use, connect the external water supply pipe to the water inlet pipe 705, and then supply water to the inside of the connecting shell 702, so that the inside of the connecting shell 702 and the water bag 703 are filled with water. Since the inside of the water bag 703 is heavier after being filled with water, and the lower side contacts the ground more evenly, it can prevent sound from spreading outward from the gap between the soundproof cover 1 and the ground. In addition, the outer wall of the water bag 703 contacts the ground, which can effectively reduce the sound generated by ground vibration and achieve the purpose of reducing noise.

[0034] The humidification mechanism 704 includes a fixed base 401. The outer wall of the fixed base 401 is fixedly connected to the upper side of the outer wall of the water bag 703. A connecting frame 402 is fixedly connected to the upper side of the fixed base 401. A motor 403 is fixedly connected to the inner wall of the connecting frame 402. Circular holes are provided on both the upper and lower sides of the water bag 703. An upper fixing tube 404 is fixedly connected to the inner wall of the circular hole on the upper side of the water bag 703. The upper end and lower end of the upper fixing tube 404 are located on the upper side and inside the water bag 703, respectively. The upper end of the upper fixing tube 404 is fixedly connected to the lower side of the outer wall of the fixed base 401. The output end of motor 403 extends through upper fixed tube 404 to the lower side of upper fixed tube 404. The output end of motor 403 is rotatably connected to the inner wall of upper fixed tube 404 via bearing. A rotating rod 405 is fixedly connected to the lower side of the output end of motor 403. The outer wall of rotating rod 405 is a hexagonal prism structure. A rotating block 406 is sleeved on the outer wall of rotating rod 405. A lower fixed tube 407 is threadedly connected to the outer wall of rotating block 406. The upper side of lower fixed tube 407 is fixedly connected to the lower side of the outer wall of upper fixed tube 404. The lower outer wall of lower fixed tube 407 is connected to the lower side of water bag 703. The inner wall of the circular hole is fixedly connected. The lower side of the outer wall of the rotating block 406 is rotatably connected to the connecting pipe 408 via a bearing. Four lifting rods 409 are fixedly connected to the lower side of the connecting pipe 408. The rotating rod 405 is a hollow structure with an opening at the bottom. A water inlet hole 410 is opened in the middle of the rotating rod 405. An extension pipe 411 is inserted into the lower side of the inner wall of the rotating rod 405. The lower end of the extension pipe 411 extends to the outside of the rotating rod 405. A connecting rod 412 is fixedly connected to the outer wall of the extension pipe 411. One end of the connecting rod 412 is fixedly connected to the lower side of the outer wall of the connecting pipe 408. The nozzle 413 is rotatably connected to the lower side of 11 via a bearing. The rotating block 406 can rotate synchronously with the rotating rod 405. When the rotating block 406 rotates, it can drive the connecting pipe 408 and the lifting rod 409 to move downward. When the lifting rod 409 moves downward, its lower end can extend to the lower outside of the lower fixed pipe 407. The water inlet 410 is located on the upper side of the extension pipe 411. The diameter of the roller 605 is greater than the vertical width of the fixed plate 604, and the lower side of the fixed plate 604 is higher than the lower side of the roller 605. The extension stroke of the hydraulic cylinder 602 is greater than the difference between the outer diameter and the inner diameter of the water bag 703.

[0035] While filling the interior of the connecting shell 702 with water, the motor 403 can be started to drive the rotating rod 405 to rotate. Since the outer wall of the rotating rod 405 is a hexagonal prism structure and the rotating block 406 is sleeved on the outside of the rotating rod 405, the rotating rod 405 drives the rotating block 406 to rotate. Since the outer wall of the rotating block 406 is threadedly connected to the inner wall of the lower fixed pipe 407, and the lower fixed pipe 407, upper fixed pipe 404, and fixed seat 401 are fixed and cannot rotate, the rotating block 406 will descend when it rotates, thereby driving the connecting pipe 408 and the lifting rod 409 to descend, so that the lifting rod 409 extends to the lower fixed pipe 408. On the outside of 7, the lifting rod 409 contacts the ground and then the lower fixing tube 407 is moved upward by the reverse force of the rotating block 406, thereby causing the lower side of the water bag 703 to be partially lifted. At the same time, the rotating block 406 moves down to the lower side of the water inlet hole 410. The water inside the water bag 703 will flow into the interior of the rotating rod 405 through the water inlet hole 410. Subsequently, due to the continuous external water supply to the interior of the water bag 703, the water will be sprayed outward through the extension pipe 411 and the nozzle 413, thereby humidifying the ground below the water bag 703. The ground vibration ability is reduced after humidification, thereby reducing the noise generated by ground vibration.

[0036] Then, the motor 403 drives the rotating rod 405 and the rotating block 406 to reverse, causing the lifting rod 409 and the nozzle 413 to retract back into the lower fixed tube 407. Since the rotating block 406 moves to the upper side of the water inlet 410, the water flow inside the water bag 703 is blocked by the rotating block 406, and the water in the water bag 703 will not flow out. At this time, the water bag 703 is in contact with the ground to prevent the ground water from evaporating, thereby increasing the continuous noise reduction market.

[0037] A method for stabilizing and reducing noise in civil engineering road construction involves several steps. Before construction, underground pipelines along the route are detected and protected to prevent unnecessary disruption to the project. Project management personnel contact the planning bureau to facilitate the handover of measurement control points, which are then re-measured according to specifications. A measurement control network is established to determine the road centerline, construction red line, and construction layout. Based on a thorough understanding of the design documents, the surveying and design unit conducts on-site measurement briefings, identifying benchmarks, guide stakes, and intersection stakes according to the design drawings, and recording stake handover. For measurement markers within the construction area, temporary facilities are promptly erected according to the overall construction plan and site conditions, taking into account fire prevention and electrical leakage prevention. Several soundproof enclosures 1 from this device are then spliced ​​together, ensuring that adjacent soundproof enclosures... The connectors 2 and 3 of the soundproof cover 1 are spliced ​​together to form a shield along the construction section. Note that the inner wall of the soundproof cover 1 needs to be located on the outer side of the construction area. After the construction machinery is driven into the interior of the soundproof cover 1, the lighting equipment is hung on the upper inner surface of the soundproof cover 1 to keep the interior of the soundproof cover 1 well lit. Windows can be opened on the sealing plate 4 according to the actual soundproofing needs. If the soundproofing requirements are high, the sealing plates 4 on both sides of the soundproof cover 1 are completely attached to the shield formed by the soundproof cover 1. Then, the sealing plates 4 are fixed to the soundproof cover 1 with bolts. Water is supplied to the water bag 703 and the connecting shell 702 through the external water supply device and the water inlet pipe 705. The water bag 703 and the connecting shell 702 are expanded by water flushing, so that the lower side of the water bag 703 is further attached to the road surface. Then, the machinery is used to carry out road construction inside the soundproof cover 1.
