Description

Technical Field

[0001] This invention relates to the field of bridge deck construction technology, and more specifically, to a bridge deck construction device and construction method for elevated bridges. Background Technology

[0002] Elevated bridge deck construction equipment refers to one or more types of specialized equipment and mechanical systems specifically developed and designed to meet the high-altitude, large-span, and high-precision construction needs of elevated bridge decks (including beam erection, bridge deck structural layer pouring, reinforcement layout, surface leveling and compaction, etc.).

[0003] Traditional bridge deck geotextile laying operations primarily rely on manual labor supplemented by simple tools. The process involves manually transporting geotextile rolls to the designated area on the bridge deck, manually adjusting the roll's position, unfolding it section by section, and then compacting it using tools such as scrapers and ordinary rollers. However, this method has several unavoidable technical drawbacks in bridge deck construction scenarios: Firstly, the construction space on bridge decks is relatively narrow and often involves a certain slope, such as bridge approach spans or curved bridge decks. When manually unfolding the geotextile, uneven stress on the slope can easily lead to fabric misalignment and wrinkles. If wrinkles are not smoothed in time, they will form interlayer voids, which will easily lead to cracking and delamination under the load of the pavement layer later. On the other hand, during the storage, transportation and transfer of geotextiles to the bridge deck, cement residue, sand particles and other impurities are easily attached to the surface. Manual cleaning is limited by the bridge deck working environment, which not only makes the cleaning inefficient, but also makes it difficult to completely remove impurities in the gaps. Residual impurities will damage the bonding effect between the geotextile and the concrete base layer, weakening its seepage prevention and stress buffering functions. In view of this, we propose a construction device and construction method for elevated bridge decks. Summary of the Invention

[0004] The purpose of this invention is to provide a construction device and method for elevated bridge decks, in order to solve the problems mentioned in the background art. When laying geotextiles mainly by hand with the assistance of simple tools, the narrow space and slope of the bridge deck make it easy for the fabric to shift and wrinkle, resulting in interlayer voids and subsequent cracking and delamination. In addition, the impurities attached to the surface of the geotextile are difficult to clean thoroughly by hand, which will damage its adhesion to the concrete base and weaken its seepage prevention and stress buffering functions.

[0005] To solve the above-mentioned technical problems, one of the objectives of this invention is to provide a bridge deck construction device for viaducts, including a mobile trolley. The bottom of both ends of the mobile trolley is equipped with casters. A storage tank for storing liquid is fixedly installed on one side of the top of the mobile trolley. An adjustable peeling mechanism is provided on one side of the storage tank. The adjustable peeling mechanism adapts to geotextiles of different thicknesses by relying on its built-in elastic element. The adjustable peeling mechanism smooths out the wrinkles on the surface of the geotextile while peeling off impurities. The storage tank is equipped with a winding mechanism inside, which is used to soak the wound geotextile in liquid; On the other side of the top of the mobile cart is a compaction mechanism. During the laying process, the geotextile released by the winding mechanism is compacted in real time, so that the geotextile is tightly attached to the concrete ground.

[0006] As a further improvement to this technical solution, the adjustable peeling mechanism includes a limiting frame fixedly connected to one side of the storage tank. The top and bottom of the limiting frame are fixedly connected to support plates. The bottom surface of the support plate is fixedly connected to a damping rod, and the bottom of the damping rod is fixedly connected to a slider.

[0007] As a further improvement to this technical solution, the top and bottom surfaces of the limiting frame are provided with straight grooves that are adapted to the slider, and a flexible brush is fixedly connected to the bottom surface of the slider.

[0008] As a further improvement to this technical solution, the winding mechanism includes a winding roller that is rotatably connected to the inner wall of the storage tank. The winding roller is internally engaged with a limiting rod, and the inner wall of the winding roller is provided with a groove that matches the limiting rod.

[0009] As a further improvement to this technical solution, one end of the limiting lever passes through the storage tank and is engaged with the first synchronous wheel, while the other end is rotatably connected to a positioning disc. The positioning disc is connected to the outer wall of the storage tank by bolts, and the first synchronous wheel is rotatably connected to the storage tank.

[0010] As a further improvement to this technical solution, a timing belt is sleeved on the surface of the first timing pulley, and a second timing pulley is sleeved inside the timing belt.

[0011] As a further improvement to this technical solution, the compaction mechanism includes two fixed plates on both sides of the top surface of the mobile trolley. Two inclined rods are fixedly connected to one side of the two fixed plates, and a hydraulic rod is rotatably connected to one side of the two inclined rods. A compaction roller is rotatably connected between the two inclined rods.

[0012] As a further improvement to this technical solution, the mobile trolley is provided with an electric slide rail and a guide roller. The guide roller includes two electric sliders that are slidably connected inside the electric slide rail. The tops of the two electric sliders are fixedly connected to two brackets, and the guide roller is rotatably connected between the two brackets.

[0013] As a further improvement to this technical solution, a filter plate is movably installed at the bottom of the storage tank, and the side of the storage tank where the first synchronous wheel is installed is engraved with scales. The inner wall of the second synchronous wheel is connected to the shaft of the movable universal wheel.

[0014] The second objective of this invention is to provide a method for constructing an elevated bridge deck, applicable to any of the elevated bridge deck construction devices described above, comprising the following steps: The first step is to prepare for construction by clearing debris from the bridge deck base and checking its flatness, while also moving the mobile cart to the work area. The second step is to lay the geotextile. The geotextile is released from the winding mechanism. The angle of the compaction mechanism is adjusted according to the slope of the bridge deck. While the trolley is being pushed, the geotextile is compacted in real time by the compaction mechanism to ensure that the geotextile is tightly bonded to the concrete base. The third step is to allow the geotextile to be recycled after the laying is completed. The adjustable peeling mechanism will simultaneously remove impurities and smooth out wrinkles, and then the winding mechanism will collect it. The fourth step is to carry out subsequent paving work on the bridge deck (such as asphalt paving) and perform finished product maintenance to ensure the overall structural stability and durability of the bridge deck.

[0015] The beneficial effects of this invention are: On the one hand, when the geotextile is rolled up, it passes through the flexible brush on one side of the limiting frame. The slider can slide up and down in the straight groove under the action of the damping rod and elastic element. When geotextiles of different thicknesses pass through, the flexible brush is subjected to different pressures, and the slider is adjusted up and down accordingly, so that the brush body always fits the fabric surface and maintains a constant cleaning pressure. It not only removes the surface attachments, but also uses the pushing action of the bristles to smooth out the wrinkles. Its adjustment action is triggered entirely by the change in fabric thickness, without the need for additional control. It is responsive and highly adaptive. On the other hand, the hydraulic rod pushes the inclined rod to rotate around the fixed plate, which drives the compaction roller to press down onto the surface of the geotextile. As the trolley moves forward, the compaction roller rolls continuously on the bridge surface to apply pressure. Since the compaction action occurs at the moment when the geotextile has just finished flattening and has not yet stopped deforming, it is seamlessly connected with the peeling and unwinding actions in time and space, effectively preventing air and local curling, and ensuring that the laid geotextile is tightly attached to the concrete base. In addition, the second synchronous wheel is connected to the pivot of the omnidirectional wheel. When the trolley moves forward, the omnidirectional wheel rotates, which drives the second synchronous wheel to rotate. Then, the first synchronous wheel is driven to rotate through the synchronous belt drive, thereby driving the limit lever and the storage roller to unwind synchronously. This ensures that the release speed of the geotextile is always matched with the moving speed of the trolley, avoiding the fabric from being stretched too tightly or slack due to manual control or motor delay, and achieving tension self-balance.

[0018] 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. Example 1

[0019] like Figures 1-8 As shown, one of the objectives of this invention is to provide a construction device for an elevated bridge deck, including a mobile trolley 100. The bottom of both ends of the mobile trolley 100 is equipped with casters 101. A storage tank 200 for storing liquid is fixedly installed on one side of the top of the mobile trolley 100. An adjustable peeling mechanism 300 is provided on one side of the storage tank 200. The adjustable peeling mechanism 300 adapts to geotextiles of different thicknesses by relying on its built-in elastic element. The adjustable peeling mechanism 300 smooths out the wrinkles on the surface of the geotextile while peeling off impurities. The storage tank 200 is equipped with a winding mechanism 400 for immersing the wound geotextile in liquid; On the other side of the top of the mobile cart 100, there is a compaction mechanism 500 for adapting to different bridge deck slopes. During the laying process, the compaction mechanism 500 compacts the geotextile released by the winding mechanism 400 in real time, so that the geotextile adheres tightly to the concrete ground.

[0020] Therefore, based on the above features, the improvements of the present invention will be described in detail: Considering that during the construction of viaduct decks, geotextiles are typically laid on the concrete surface as an isolation or waterproof layer to prevent erosion of the concrete structure, traditional construction methods often involve manual laying, which suffers from low efficiency, uneven laying, and poor adhesion to the base layer. Especially in large-area bridge deck construction, manual operation makes it difficult to ensure the continuity and flatness of the geotextiles. Furthermore, the bridge deck base layer often contains dust, debris, and other impurities, which, if not removed, will affect the bonding effect of the geotextiles. Additionally, geotextiles are prone to wrinkling during transportation and storage, and direct laying will also affect the final construction quality. Meanwhile, some projects require the geotextiles to be soaked in liquid (such as impregnated with waterproofing agents or curing solutions) before laying to enhance their functionality, but existing equipment cannot achieve integrated soaking, flattening, cleaning, laying, and compaction operations. Therefore, during the geotextile installation on the bridge deck, firstly, a mobile trolley 100 equipped with casters 101 at the bottom is pushed to flexibly transport the equipment to the target construction area on the bridge deck; then, one end of the geotextile is pulled from the winding mechanism 400 inside the storage tank 200 on the mobile trolley 100 and laid flat at the designated position on the bridge deck; subsequently, according to the current bridge deck slope, the compaction mechanism 500 on the other side of the mobile trolley 100 is adjusted to a suitable angle to ensure that the compaction mechanism 500 can fit against the bridge deck base layer; as the winding mechanism 400 gradually releases the geotextile, the compaction mechanism 500 simultaneously compacts the released geotextile in real time, ensuring that the geotextile is tightly bonded to the concrete surface; the following effects are achieved: Firstly, the mobile trolley 100 can easily move to different areas of the bridge deck via the omnidirectional casters 101 at the bottom, solving the problem of laborious manual handling of geotextile rolls and significantly shortening the equipment transfer and operation preparation time. At the same time, the continuous operation of releasing geotextile and real-time compaction avoids the process interval of manual segmented compaction, significantly improving the efficiency of geotextile laying on the bridge deck. Secondly, the compaction mechanism 500 can adjust its angle according to the bridge deck slope to ensure uniform compaction in different slope areas such as approach bridges and curved bridge decks. This effectively avoids the problem of geotextile slippage in steep slope areas and damage to the geotextile surface in gentle slope areas, promotes close bonding between the geotextile and the concrete base layer, enhances the bonding stability between the bridge deck pavement layer and the base layer, and reduces later cracking, delamination and other defects. Thirdly, the adjustable peeling mechanism 300 features an elastic element design that allows it to adapt to geotextiles of different thicknesses without the need for frequent manual adjustments to the mechanism parameters. During the recycling process, it simultaneously removes impurities and smooths wrinkles, which not only avoids contamination of the recycled geotextile by impurities but also ensures the flatness of the fabric surface, laying a good foundation for the secondary use or subsequent processing of the geotextile and reducing material waste costs. Based on the above, the specific structure will be disclosed in detail: To achieve smoothing and impurity removal from the geotextile, the adjustable stripping mechanism 300 is disclosed in detail, as follows: Figure 2 and Figure 3 As shown, the adjustable peeling mechanism 300 includes a limiting frame 301 fixedly connected to one side of the storage tank 200. The top and bottom of the limiting frame 301 are fixedly connected to a support plate 302. The bottom surface of the support plate 302 is fixedly connected to a damping rod, and the bottom of the damping rod is fixedly connected to a slider 303. The top and bottom surfaces of the limiting frame 301 are provided with straight grooves that are adapted to the slider 303. The bottom surface of the slider 303 is fixedly connected to a flexible brush 304. Therefore, when the geotextile passes inside the limiting frame 301, the slider 303, under the elastic action of the damping rod, will automatically adjust its position according to the actual thickness of the geotextile, causing the flexible brush 304 fixed on the bottom surface to always remain in contact with the geotextile surface. On the one hand, during the continuous contact between the flexible brush 304 and the geotextile surface, it can effectively clean and peel off impurities such as sand, gravel, and cement residue attached to the fabric surface, avoiding impurities from affecting the subsequent recycling or secondary laying quality of the geotextile. On the other hand, the damping rod drives the slider 303 and the flexible brush 304 to adapt to geotextiles of different thicknesses, ensuring that the force exerted by the brush on the geotextile surface is uniform and appropriate. While cleaning impurities, it can also produce a slight smoothing effect on the fabric surface, reducing wrinkles caused by uneven force during the recycling process, maintaining the flatness of the fabric surface, and providing good conditions for the storage or reuse of the geotextile.

[0021] Furthermore, to prevent wrinkles, stretching deformation, or breakage of the fabric due to uneven winding and unwinding, the winding mechanism 400 is disclosed in detail, specifically as follows: Figure 4 and Figure 5 As shown, the winding mechanism 400 includes a winding roller 401 rotatably connected to the inner wall of the storage tank 200. The winding roller 401 is internally engaged with a limiting rod 402, and the inner wall of the winding roller 401 is provided with a groove that matches the limiting rod 402. One end of the limiting rod 402 passes through the storage tank 200 and is engaged with a first synchronous pulley 403, while the other end is rotatably connected to a positioning disc 404. The positioning disc 404 is connected to the outer wall of the storage tank 200 by bolts. The first synchronous pulley 403 is rotatably connected to the storage tank 200. A synchronous belt 405 is sleeved on the surface of the first synchronous pulley 403, and a second synchronous pulley is sleeved inside the synchronous belt 405. Therefore, the snap-fit ​​design between the limiting rod 402 and the collecting roller 401, and the support of the positioning plate 404 for the limiting rod 402, can effectively prevent the collecting roller 401 from shifting, shaking or slipping during rotation, ensuring that the geotextile can be evenly wound on the collecting roller 401 when it is rolled up, and maintain a uniform output speed when it is released, preventing the fabric from wrinkling, stretching deformation or breaking due to uneven winding and unwinding, and providing a stable fabric surface state for subsequent compaction, recycling and other processes; The storage roller 401 is set inside the storage tank 200. After the geotextile is rolled up, it can be directly immersed in the liquid in the storage tank 200 without the need for additional transfer of the roll. This simplifies the connection process of "rolling-immersion" and allows the geotextile to fully contact the liquid, such as to achieve adhesive impregnation, cleaning and maintenance, etc., to ensure the functional performance of the geotextile, while avoiding secondary pollution or damage to the fabric surface during the transfer process. With the help of the transmission structure of the synchronous pulley and synchronous belt 405, the winding mechanism 400 can be linked with the power unit's omnidirectional wheel 101 to realize the mechanized operation of geotextile winding and unwinding, replacing the laborious traditional method of manually rotating the roll, and greatly improving the winding and unwinding speed; moreover, the power transmission is stable and controllable, and the winding and unwinding rate can be adjusted according to the laying or recycling progress, forming a coordinated operation with the compaction mechanism 500 and the adjustable stripping mechanism 300, further optimizing the continuity and efficiency of the overall construction process.

[0022] However, to achieve a zero-air-gap relationship between the geotextile and the bridge deck, the compaction mechanism needs to be detailed, specifically as follows: Figure 6 and Figure 7 As shown, the compaction mechanism 500 includes two fixed plates 501 on both sides of the top surface of the mobile trolley 100. Two inclined rods 502 are fixedly connected to one side of the two fixed plates 501. A hydraulic rod 503 is rotatably connected to one side of the two inclined rods 502, and a compaction roller 504 is rotatably connected between the two inclined rods 502. Therefore, by utilizing the adjustable angle of the inclined rod 502 by the hydraulic rod 503, the compaction mechanism 500 can flexibly adjust the tilt angle of the compaction roller 504 according to the actual slope of the bridge deck, such as steep slopes of approach bridges and gentle areas of the bridge deck, to ensure that the compaction roller 504 always maintains full contact with the surface of the geotextile, and avoids inadequate compaction in some areas due to changes in slope, such as the compaction roller 504 being suspended in the air on steep slopes and uneven pressure on gentle slopes, thus achieving uniform compaction coverage of the entire bridge deck paving area.

[0023] The hydraulic rod 503 has stable pressure output characteristics. By controlling its extension and retraction, the pressure of the compaction roller 504 on the geotextile can be precisely adjusted. For thicker geotextiles, the pressure can be increased to ensure that the fabric surface is tightly bonded to the base layer. For thinner geotextiles, the pressure can be reduced to avoid damage to the fabric surface. This effectively solves the problem of uncontrollable pressure in traditional manual compaction, promotes a stable bond between the geotextile and the concrete base layer, and reduces the risk of cracking and delamination of the bridge deck pavement layer in the later stage.

[0024] The rigid connection structure between the fixed plate 501 and the inclined bar 502 provides stable support for the compaction roller 504, preventing the compaction trajectory from deviating due to the shaking of the mechanism during the compaction process. At the same time, the rolling compaction design of the compaction roller 504 reduces the frictional resistance with the geotextile while ensuring the compaction effect. It can be used in conjunction with the movement of the mobile trolley 100 to achieve continuous and efficient compaction without the need for repeated manual adjustments or segmented compaction, which significantly improves the work efficiency and quality stability of bridge deck geotextile laying.

[0025] Next, to guide the geotextile, specifically as follows: Figure 8 As shown, the mobile trolley 100 is provided with an electric slide rail, and the mobile trolley 100 is also provided with a guide roller 600. The guide roller 600 includes two electric sliders that are slidably connected inside the electric slide rail. The tops of the two electric sliders are fixedly connected to two brackets, and the guide rollers are rotatably connected between the two brackets. Therefore, the guide roller, which is rotatably connected between the two supports, can form rolling contact with the geotextile during the process of releasing the geotextile from the winding mechanism 400 to the bridge deck. By rotating itself, it provides stable guidance and support for the geotextile, avoiding the geotextile from shifting, tangling or getting stuck during the release process due to lack of guidance. This ensures that the geotextile is always laid flat along the preset path, reducing wrinkles or tensile damage to the geotextile caused by path deviation.

[0026] Specifically, a filter plate 201 is movably installed at the bottom of the storage tank 200, and a scale is engraved on the side of the storage tank 200 where the first synchronous wheel 403 is installed. The inner wall of the second synchronous wheel is connected to the shaft of the movable universal wheel 101. Therefore, when geotextile is soaked in the tank, a small amount of impurities such as fine sand and fiber debris may remain on the surface of the fabric. These impurities will be deposited or suspended with the flow of liquid. The filter plate 201 can intercept such impurities, prevent them from accumulating in the liquid, avoid impurities from re-adhering to the surface of the geotextile and affecting the soaking effect, and at the same time reduce the wear of impurities on other components in the tank such as the winding mechanism 400, extend the circulation time of the liquid, and reduce the frequency and cost of liquid replacement during construction.

[0027] The second objective of this invention is to provide a method for constructing an elevated bridge deck, applicable to any of the above-mentioned elevated bridge deck construction devices, comprising the following steps: The first step is to prepare for construction by clearing debris from the bridge deck base and checking its flatness, while also moving the mobile trolley 100 to the work area. The second step is to lay the geotextile. The geotextile is released from the winding mechanism 400. The angle of the compaction mechanism 500 is adjusted according to the slope of the bridge deck. While the trolley is being pushed, the geotextile is compacted in real time by the compaction mechanism 500 to ensure that the geotextile is tightly bonded to the concrete base. The third step is to allow the geotextile to be recycled after the laying is completed. The adjustable peeling mechanism 300 will simultaneously remove impurities and smooth out wrinkles, and then the winding mechanism 400 will collect it. The fourth step is to carry out subsequent paving work on the bridge deck, such as asphalt paving, and to perform finished product maintenance to ensure the overall structural stability and durability of the bridge deck.

[0028] Working principle of the invention: First, check the status of each component of the device to ensure that the mobile trolley 100, storage tank 200, adjustable peeling mechanism 300, winding mechanism 400, compaction mechanism 500 and guide roller 600 are all in normal operation. Inject an appropriate amount of liquid for treating geotextile into the storage tank 200, and observe the liquid level through the scale on one side of the storage tank 200 to ensure that the liquid meets the construction requirements. Also, ensure that the filter plate 201 is installed in place to filter impurities in the liquid. Install the geotextile to be laid on the winding roller 401 of the winding mechanism 400 and fix the geotextile with the limit rod 402 to prevent the geotextile from shifting during winding or release. After soaking, the geotextile is drawn out from the storage tank 200 and guided by the guide roller 600. According to the construction requirements, the electric slider slides in the electric slide rail, driving the support and guide roller to adjust the position, ensuring that the geotextile can move smoothly along the preset path and be accurately delivered to the bridge deck to be paved. During the geotextile laying process, the compaction mechanism 500 works synchronously, and the hydraulic rod 503 adjusts its length according to the bridge deck conditions, driving the inclined rod 502 to finely adjust its angle, so that the compaction roller 504 is always in close contact with the geotextile surface, and the released geotextile is compacted in real time, which promotes the geotextile to adhere tightly to the concrete ground and improves the laying quality. The winding mechanism 400 starts operating. The second synchronous wheel rotates with the shaft of the movable universal wheel 101, and drives the first synchronous wheel 403 to rotate through the synchronous belt 405, which in turn causes the winding roller 401 to rotate, gradually winding up the geotextile. During the winding process, the geotextile first passes through the adjustable peeling mechanism 300. This mechanism relies on the built-in elastic element, and its slider 303 adaptively adjusts its position in the straight groove, driving the flexible brush 304 to peel off impurities on the surface of the geotextile, while smoothing out the wrinkles on the fabric surface, ensuring that the geotextile surface is flat and clean, and preparing for subsequent laying. The treated geotextile continues to move and enters the storage tank 200. The winding mechanism 400 soaks the wound geotextile in the liquid in the storage tank 200, allowing the geotextile to fully absorb the liquid and enhance its adhesion to the concrete floor. During this process, the filter plate 201 inside the storage tank 200 filters impurities in the liquid to ensure the cleanliness of the liquid and prevent impurities from affecting the treatment effect of the geotextile. During construction, workers can monitor the remaining liquid level in real time through the scale of the storage tank 200 and replenish the liquid in a timely manner. Simultaneously, based on the geotextile laying progress, they can flexibly adjust the position of the guide roller 600 and the compaction force of the compaction mechanism 500 to ensure a stable and efficient construction process until the geotextile laying on the bridge deck is completed. (Note: After the geotextile is rolled up, the bolts on the positioning plate 404 can be loosened, allowing the limit rod 402 and the collecting roller 401 to be disassembled and the geotextile removed.)

10. A method for constructing an elevated bridge deck, applied to the elevated bridge deck construction device described in any one of claims 1-9, characterized in that, Includes the following steps: First step: First, prepare for construction by cleaning up debris on the bridge deck base and checking its flatness, and at the same time, transport the mobile cart (100) to the work area. The second step is to lay the geotextile. The geotextile is released from the winding mechanism (400). The angle of the compaction mechanism (500) is adjusted according to the slope of the bridge deck. While pushing the trolley to move, the geotextile is compacted in real time by the compaction mechanism (500) to ensure that the fabric is tightly attached to the concrete base. The third step is to recycle the geotextile after it has been laid. The geotextile is then removed by the adjustable peeling mechanism (300) and the wrinkles are smoothed out. The geotextile is then collected by the winding mechanism (400). The fourth step is to carry out subsequent paving work on the bridge deck (such as asphalt paving) and perform finished product maintenance to ensure the overall structural stability and durability of the bridge deck.
