Description

Technical Field

[0001] The invention belongs to the technical field of cast-in-place continuous beam maintenance, and mainly relates to an automatic spraying maintenance system for a cantilever continuous beam. Background Art

[0002] Cantilever continuous beams require maintenance, mainly based on the following important reasons: The strength development of concrete requires suitable temperature and humidity conditions. Curing can provide a relatively stable environment for concrete, allowing cement to fully hydrate, thereby promoting the normal growth of concrete strength. In large structures such as cantilever continuous beams, the normal development of concrete strength is crucial to bearing the weight of the structure itself and the loads during subsequent construction and use.

[0003] During the drying process of concrete, moisture will gradually dissipate, resulting in volume shrinkage. If the concrete surface is not maintained in time, the moisture evaporates too quickly and the internal moisture cannot be replenished in time, which will cause tensile stress on the surface. When the tensile stress exceeds the tensile strength of the concrete, shrinkage cracks will appear.

[0004] A large amount of heat is generated during cement hydration, which increases the temperature inside the concrete. In large-volume concrete structures such as cantilever continuous beams, the internal heat is not easy to dissipate, and the temperature difference between the inside and outside is large, which will cause temperature stress. Through maintenance and taking appropriate temperature control measures, such as covering with insulation materials, the temperature difference between the inside and outside can be reduced, the temperature stress can be reduced, and the generation of temperature cracks can be prevented.

[0005] Good maintenance can make the microstructure of concrete denser, reduce pores and cracks, and thus improve the durability indicators of concrete such as impermeability and frost resistance. For cantilever continuous beams, which are exposed to the natural environment for a long time, the improvement of durability can extend their service life and reduce maintenance costs.

[0006] The cantilever continuous beam is an integral structure, and the concrete properties of each part are interrelated. Through comprehensive and standardized maintenance, the concrete properties of each part are guaranteed to be uniform, so that the structure can work together when subjected to stress, thus ensuring the integrity and stability of the entire structure.

[0007] The existing cantilever cast-in-place continuous beam maintenance method is to sprinkle water on the continuous beam, but a large amount of water will fall from the continuous beam to the ground, so that the water cannot be fully used for the maintenance of the continuous beam, resulting in a waste of water. Summary of the invention

[0008] The invention provides an automatic spraying curing system for a cantilever continuous beam, so as to solve the problem of water waste caused by the curing method of the cantilever cast-in-place continuous beam in the prior art.

[0009] To solve the above problems, the present invention adopts the following technical solutions: An automatic spraying maintenance system for a cantilever continuous beam comprises a truss arranged on the continuous beam, a water pipe arranged on the truss, and a water tank connected to the water pipe, wherein the truss comprises an outer mold truss slidably mounted on the outer side of the continuous beam and an inner mold truss slidably mounted on the inner side of the continuous beam, the water pipe is provided with a plurality of sprinkler heads for watering, and the outer mold truss and the inner mold truss are both provided with the water pipe, so that the water pipe performs watering maintenance on the outer side and the inner side of the continuous beam; The outer formwork truss is provided with a recovery piece located on the lower side of the continuous beam, and the recovery piece has a recovery groove so that the water on the outer side of the continuous beam can fall into the recovery groove; The inner mold truss is fixedly equipped with a scraper, which moves with the inner mold truss to scrape the water at the bottom of the inner side of the continuous beam so that the water falls into the recovery tank; The notch of the recovery tank has a filter plate for filtering debris, and a recovery pipe is provided on the outer mold truss. One end of the recovery pipe passes through the filter plate and is inserted into the recovery tank, and the other end of the recovery pipe is connected to the water tank. A recovery pump is provided on the recovery pipe to extract water in the recovery tank and return it to the water tank.

[0010] It has the following beneficial effects: during the maintenance of the continuous beam, the water falling from the continuous beam will fall into the recovery tank, the filter plate will filter the cured water, and then the recovery pump will re-transport the filtered water in the recovery tank to the water tank, thereby realizing the reuse of the maintenance water and reducing water waste.

[0011] Furthermore, the bottom of the recovery tank is in an arc shape that is concave downward.

[0012] The invention has the following beneficial effects: the downwardly concave arc-shaped groove bottom can make the water that falls into the recovery groove be collected in the middle, which makes it more convenient for the recovery pipe to recover the water.

[0014] The invention has the following beneficial effects: the recovery pipe is located at the lowest point, so that the water in the recovery tank can be fully recovered, thereby reducing the residual water in the recovery tank.

[0015] Furthermore, the filter plate can be detachably assembled on the recovery member, an annular support seat is provided on the groove wall of the recovery groove, and the filter plate is fixed to the annular support seat by bolts.

[0016] Further, the outer formwork truss includes a left truss for erecting on the left side of the continuous beam and a right truss for erecting on the right side of the continuous beam, the recovery member is arranged between the left truss and the right truss, the left truss half wraps the left wing plate, the left side wall and the lower side of the continuous beam, and the right truss half includes the right wing plate and the right side wall of the continuous beam; The water pipe includes a first branch pipe, a second branch pipe and a third branch pipe, and the nozzles include a first nozzle, a second nozzle and a third nozzle.

The third branch pipe is arranged on the right truss, and a plurality of the third nozzles are arranged on the third branch pipe to sprinkle water on the right wing plate and the right wall of the continuous beam.

[0017] The invention has the following beneficial effects: by designing a truss, the first branch pipe, the second branch pipe and the third branch pipe are arranged on the truss, and each nozzle sprays water toward the continuous beam for maintenance. At the same time, the truss is slidably assembled on the continuous beam. When a section of the continuous beam has been maintained, each branch pipe is removed from the water tank, and the truss is pushed to move to the lower section of the continuous beam. Then each branch pipe is connected to the water tank to carry out water spraying maintenance on the lower section of the continuous beam. In this way, the problem of multiple relocations of the spraying maintenance system due to the advancement of the cast-in-place concrete stage, which causes complicated maintenance procedures, is avoided. At the same time, the problem of low efficiency and labor-consuming manual watering maintenance is also avoided.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0032] In this embodiment, an automatic spray curing system for a cantilever continuous beam is used on a cantilever cast-in-place continuous beam. The cantilever cast-in-place continuous beam in this embodiment includes a main body 1 and a left wing plate 2 and a right wing plate 3 respectively arranged on the left and right sides of the main body 1. The top surfaces of the left wing plate 2 and the right wing plate 3 are flush with the top surface of the main body 1, wherein the continuous beam has a left side wall, a right side wall and a lower side surface, and the continuous beam also has a cavity 4. The continuous beam is a concrete structure, which is cast using raw materials such as cement, sand and gravel, and steel. After casting, it is covered and watered in time for curing. The curing time is determined according to the type of concrete and environmental conditions, and is generally not less than 7 days.

[0033] Continuous beams require maintenance mainly for the following important reasons: 1. Ensure the growth of concrete strength The strength development of concrete requires suitable temperature and humidity conditions. Curing can provide a relatively stable environment for concrete, allowing cement to fully hydrate, thereby promoting the normal growth of concrete strength. In large structures such as cantilever continuous beams, the normal development of concrete strength is crucial to bearing the weight of the structure itself and the loads during subsequent construction and use.

[0034] 2. Prevent concrete cracks Shrinkage cracks: During the drying process of concrete, moisture will gradually dissipate, resulting in volume shrinkage. If the concrete surface is not maintained in time, the moisture evaporates too quickly and the internal moisture cannot be replenished in time, which will cause tensile stress on the surface. When the tensile stress exceeds the tensile strength of the concrete, shrinkage cracks will appear.

[0035] Temperature cracks: A large amount of heat is generated during cement hydration, which increases the temperature inside the concrete. In large-volume concrete structures such as cantilever continuous beams, the internal heat is not easy to dissipate, and the temperature difference between the inside and outside is large, which will cause temperature stress. Through maintenance and taking appropriate temperature control measures, such as covering with insulation materials, the temperature difference between the inside and outside can be reduced, the temperature stress can be reduced, and the generation of temperature cracks can be prevented.

[0036] 3. Improve the durability of concrete Good maintenance can make the microstructure of concrete denser, reduce pores and cracks, and thus improve the durability indicators of concrete such as impermeability and frost resistance. For cantilever continuous beams, which are exposed to the natural environment for a long time, the improvement of durability can extend their service life and reduce maintenance costs.

[0037] 4. Ensure the integrity and stability of the structure The cantilever continuous beam is an integral structure, and the concrete properties of each part are interrelated. Through comprehensive and standardized maintenance, the concrete properties of each part are guaranteed to be uniform, so that the structure can work together when subjected to stress, thus ensuring the integrity and stability of the entire structure.

[0038] like Figure 1 As shown, in this embodiment, an automatic spraying maintenance system for a cantilever continuous beam includes a truss arranged on the continuous beam, a water pipe arranged on the truss, and a water tank 5 connected to the water pipe. The water tank 5 is arranged on the top surface of the continuous beam, and the water tank 5 is connected to the truss. The truss includes an outer mold truss slidably mounted on the outside of the continuous beam and an inner mold truss 7 slidably mounted in the cavity 4 of the continuous beam. The outer mold truss includes a left truss 6 for erecting on the left side of the continuous beam and a right truss 8 for erecting on the right side of the continuous beam. The left truss 6 half-wraps the left wing plate 2, the left side wall and the lower side of the continuous beam, and the right truss 8 half-wraps the right wing plate 3 and the right side wall of the continuous beam. The left truss 6, the right truss 8 and the inner mold truss 7 are all connected to the water tank 5.

[0039] In this embodiment, the water pipe includes a first branch pipe 9, a second branch pipe 10 and a third branch pipe 11, all of which are connected to the water tank 5. The first branch pipe 9 is arranged on the left truss 6, and a plurality of first nozzles 12 are arranged on the first branch pipe 9, and these first nozzles 12 correspond to the left wing plate 2, the left side wall and the lower side surface, respectively, so as to spray water on the left wing plate 2, the left side wall and the lower side surface of the continuous beam. The second branch pipe 10 is arranged on the inner mold truss 7, and a plurality of second nozzles 13 are arranged on the second branch pipe 10, and these second nozzles 13 correspond to the inner side wall, so as to spray water on the inner side wall of the continuous beam. The third branch pipe 11 is arranged on the right truss 8, and a plurality of third nozzles 14 are arranged on the third branch pipe 11, and these third nozzles 14 correspond to the right wing plate 3 and the right side wall, respectively, so as to spray water on the right wing plate 3 and the right side wall of the continuous beam.

[0040] A recovery member is provided between the left truss 6 and the right truss 8. The recovery member is located on the lower side of the continuous beam. A recovery groove 19 is provided in the recovery member. The notch of the recovery groove 19 faces the lower side of the continuous beam so that the water on the outer side of the continuous beam can fall into the recovery groove 19. A scraper 21 is fixedly mounted on the inner mold truss 7. The scraper 21 moves with the inner mold truss 7 to scrape the water on the inner bottom of the continuous beam so that the water falls into the recovery groove 19. In this embodiment, the movement of the inner mold truss 7 can be manually pushed, or the inner mold truss 7 can be driven by a device to move. The notch of the recovery groove 19 has a filter plate 20 for filtering debris. A recovery pipe 22 is provided on the left truss 6. One end of the recovery pipe 22 passes through the filter plate 20 and is inserted into the recovery groove 19. The other end of the recovery pipe 22 is connected to the water tank 5. A recovery pump is provided on the recovery pipe 22 to extract the water in the recovery groove 19 and return it to the water tank 5.

[0041] During the maintenance of the continuous beam, the water falling from the continuous beam will fall into the recovery tank 19, and the filter plate 20 will filter the maintained water. Then the recovery pump will transport the filtered water in the recovery tank 19 back to the water tank 5, so as to realize the reuse of the maintenance water and reduce the waste of water.

[0042] In this embodiment, a truss is designed so that the first branch pipe 9, the second branch pipe 10 and the third branch pipe 11 are all arranged on the truss, and the first nozzles 12, the second nozzles 13 and the third nozzles 14 spray water toward the continuous beam for maintenance. At the same time, the truss is slidably assembled on the continuous beam. When a section of the continuous beam has been cured, the branch pipes are removed from the water tank 5, and the truss is pushed to move to the lower section of the continuous beam. Then, the branch pipes are connected to the water tank 5 to spray water on the lower section of the continuous beam for maintenance. This avoids the problem of multiple relocations of the spraying maintenance system due to the advancement of the cast-in-place concrete stage, which causes complicated maintenance procedures. It also avoids the problem of low efficiency and labor-intensive manual watering maintenance.

[0043] In this embodiment, the bottom of the recovery tank 19 is a downwardly concave arc. The downwardly concave arc bottom can make the water that falls into the recovery tank 19 be collected in the middle, which is more convenient for the recovery pipe 22 to recover water.

[0044] One end of the recovery pipe 22 is located at the lowest point of the bottom of the arc-shaped recovery tank 19. The recovery pipe 22 is located at the lowest point to fully recover the water in the recovery tank 19 and reduce the residual water in the recovery tank 19.

[0045] The filter plate 20 can be detachably assembled on the recovery member. An annular support seat is provided on the groove wall of the recovery groove 19, and the filter plate 20 is fixed on the annular support seat by bolts.

[0046] The recovery member in this embodiment can be formed by a waterproof cloth, and the edges of the waterproof cloth are fixed to the left truss 6 and the right truss 8. After being fixed, the left and right widths of the horizontal cross section of the waterproof cloth are greater than the left and right widths of the lower side of the continuous beam. The edges of the waterproof cloth can be fixed directly to the left truss 6 and the right truss 8, or they can be fixed to the left truss 6 and the right truss 8 by multiple ropes.

[0047] In this embodiment, the left truss 6, the right truss 8 and the inner mold truss 7 are all provided with mounting rods, which extend horizontally and cantilever toward the rear side of the continuous beam, and the first nozzle 12, the second nozzle 13 and the third nozzle 14 are installed on the corresponding mounting rods. The mounting rods cantilever toward the rear side of the continuous beam, so that the first nozzle 12, the second nozzle 13 and the third nozzle 14 can spray deep into the continuous beam cavity 4. In this embodiment, the rear side of the continuous beam refers to the position after concrete pouring has been performed, and the position where concrete pouring has not been performed (or concrete pouring will be performed) is the front side.

[0048] In this embodiment, the rear side of the mounting rod is cantilevered by at least two meters, which ensures that the continuous beam cavity 4 can be more fully watered and maintained. The first nozzle 12, the second nozzle 13 and the third nozzle 14 have a spraying diameter of four meters, which can ensure full coverage of the continuous beam and ensure the quality of maintenance.

[0049] A first guide seat 15 is provided on the left and right side walls of the continuous beam. The left truss 6 and the right truss 8 are slidably assembled on the first guide seat 15 on the corresponding side. When the maintenance position changes, the left truss 6 and the right truss 8 can slide along the first guide seat 15, thereby changing the maintenance position and avoiding the migration and change of the spray maintenance system.

[0050] A second guide seat 17 is provided in the cavity 4 of the continuous beam, and the inner mold truss 7 is slidably assembled on the second guide seat 17 on the corresponding side. When the maintenance position changes, the inner mold truss 7 can slide along the second guide seat 17 to change the maintenance position, thereby avoiding the migration and modification of the spray maintenance system and saving labor.

[0051] The first guide seat 15 and the second guide seat 17 play a guiding role, so that the left truss 6, the right truss 8 and the inner mold truss 7 can slide on the continuous beam according to the maintenance position.

[0052] In order to make the left truss 6 move more easily on the continuous beam, a first roller 18 is rotatably installed on the left truss 6, and the first roller 18 is in contact with the top surface of the continuous beam to enable the left truss 6 to move on the continuous beam. At the same time, the first roller 18 plays a supporting role, supporting the left truss 6 on the continuous beam.

[0053] In order to make the right truss 8 move more easily on the continuous beam, a second roller 16 is rotatably installed on the right truss 8, and the second roller 16 is in contact with the top surface of the continuous beam to enable the right truss 8 to move on the continuous beam. At the same time, the second roller 16 plays a supporting role to support the right truss 8 on the continuous beam.

[0054] The first roller 18 and the second roller 16 are in contact with the top surface of the continuous beam to support the truss and facilitate the movement of the truss.

[0055] In this embodiment, gate valves are provided on the first branch pipe 9, the second branch pipe 10 and the third branch pipe 11. By opening and closing the gate valves on the corresponding branch pipes, the spraying of the branch pipes is controlled, thereby controlling the watering maintenance of the continuous beam by the spraying maintenance system. The flow spraying of each branch pipe can be controlled by the corresponding gate valves, so that the watering amount at the corresponding position can be determined according to the maintenance conditions at each position of the continuous beam.

[0056] The first branch pipe 9, the second branch pipe 10 and the third branch pipe 11 are respectively connected to water pumps, and the three water pumps are connected to the water tank 5 to supply water to the corresponding branch pipes. The water pumps pump water from the water tank 5, and the pumped water is sprayed to each maintenance position through the first branch pipe 9, the second branch pipe 10 and the third branch pipe 11. At the same time, the water tank 5 is connected to a water supply device, which can supply water into the water tank 5 to prevent the water tank 5 from being dry.

[0057] Each water pump is electrically connected to a controller, and each gate valve is electrically connected to the controller, so that the controller controls the operation of the corresponding gate valve and the corresponding water pump. The operation of the gate valve and the water pump is controlled by the controller, thereby controlling the watering amount during maintenance.

[0058] Temperature sensors and humidity sensors are provided on the left truss 6, the right truss 8 and the inner mold truss 7 to detect the temperature and humidity at the corresponding positions. The temperature sensor and the humidity sensor are electrically connected to the controller respectively to feed back the detected information to the controller for the controller to adjust the operation of the corresponding water pump and the corresponding gate valve.
