Description

Technical Field

[0001] This invention belongs to the technical field of membrane curing machinery and devices in large-volume concrete construction, and particularly relates to a membrane curing device and its usage method suitable for large-volume concrete. Background Technology

[0002] In civil engineering construction, after the pouring of large-volume concrete, surface lining and water curing are essential. To ensure rapid lining and curing of the poured concrete, lining and water curing must be carried out immediately after pouring. This is especially crucial after the pouring of large-volume concrete in summer or high temperatures. Currently, for large-volume concrete construction, lining is typically done manually and workers are periodically watered. This process requires a large workforce, is inefficient, labor-intensive, and involves manual operation and timely watering. Furthermore, the manual operation requires workers to walk on the poured concrete, which may cause damage. Therefore, in high-temperature climates, large-volume concrete must be promptly lining and watered for cooling and curing to prevent temperature cracks that could compromise structural safety and normal use.

[0003] A large-volume concrete membrane curing device can quickly cover the surface of poured concrete with a plastic film to prevent rapid moisture evaporation; then, a layer of geotextile is laid, and the surface is simultaneously sprayed with water to achieve the purpose of moisturizing and cooling. Existing membrane curing devices are all operated separately, and mostly rely on manual labor. The entire process is relatively complex, time-consuming, and labor-intensive, with very low efficiency in laying the film, geotextile, and watering. Therefore, to ensure the cooling effect of large-volume concrete curing, it is essential to provide a suitable membrane curing device and its application method for large-volume concrete, which is a problem that technical personnel urgently need to solve. Summary of the Invention

[0004] The main objective of this invention is to provide a membrane curing device and method suitable for large-volume concrete, which completes the entire curing process of laying the membrane, geotextile, and watering in one go, improving work efficiency, saving a lot of manpower, improving curing and cooling effects, enabling faster and more accurate control, improving the efficiency of membrane curing for large-volume concrete, and ensuring that cast-in-place large-volume concrete can be promptly covered with membrane for moisture retention and watered for cooling, effectively solving the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for curing large-volume concrete with a membrane includes a first drag frame for laying a plastic membrane, a second drag frame for laying geotextile, and a water spraying conduit valve for spraying water. The second drag frame is provided with cast-in-place concrete, and a water spraying position is provided below the cast-in-place concrete.

[0007] The first towing frame is provided with a first die-cutting blade at the rear, and the second towing frame is provided with a second die-cutting blade at the rear. The water spray pipe valve, the first die-cutting blade, and the second die-cutting blade are all controlled by the control switch operating platform.

[0008] The second towing frame is equipped with a water spraying platform plate, and a water spraying pipe is connected to the water spraying platform plate. A water tank is connected to the water spraying pipe. The four corners of the water tank are welded to the support frame. A storage battery is installed at the bottom of the support frame, and a fixed control switch operating platform is provided.

[0009] Below the battery and control switch operating platform is a track, and a laser positioning emission point is provided in the center of the track in the forward direction. The water spraying platform is provided with multiple water spraying nozzles, including a positionable water spraying nozzle, which has a positionable water spraying nozzle rotation angle.

[0010] The control switch operating platform is equipped with a water spray pipe valve switch, a second die cutter button, a start / stop device switch, a water spray pipe switch, and a second die cutter switch.

[0011] As a preferred embodiment, the battery is a traction battery, a liquid-charged battery, with a voltage of 80V and a rated capacity of 560AH; it can provide power for the entire equipment, enabling the entire equipment to be laid at a speed range of 0-5m / min, moving with the entire track.

[0012] The track is 180mm×60mm×45mm in size and has a track pitch of 60mm. It is made of three-strand rubber material with a length and width of 180mm, and the track has the largest contact area to avoid irreversible damage to the surface and interior of the cast-in-place concrete.

[0013] As a preferred embodiment, the water tank and the sprinkler head are connected by a sprinkler conduit. The sprinkler head is parallel to the film laying direction on the sprinkler platform plate. The sprinkler platform plate is a steel plate with a length of 4000mm, a width of 500mm, and a thickness of 50mm, and a row of rotating shafts for positioning the sprinkler head is provided on it.

[0014] The two ends of a row of sprinkler heads on the sprinkler platform are respectively provided with a positioning sprinkler head rotating shaft operating handle, which can be rotated clockwise or counterclockwise;

[0015] Meanwhile, the water pressure in the sprinkler pipe is controlled by the sprinkler pipe valve switch.

[0016] As a preferred embodiment, the watering platform is a steel plate with a length of 4000mm, a width of 500mm, and a thickness of 50mm, on which a row of rotating shafts for positioning water spray heads is provided; the entire watering platform, together with the water, has a certain weight, which can compact the laid plastic film and geotextile, achieving a closer contact with the surface of the cast-in-place concrete.

[0017] As a preferred embodiment, the end of the second drag frame is connected to the film-laying roller shaft, the film-laying roller shaft is provided with bundles of geotextile, both ends of the film-laying roller shaft are provided with movable drag frame buckles, and the second drag frame is provided with an elastic connecting pipe above it;

[0018] The first die-cutting blade on the first drag frame is used in the same way as the second die-cutting blade on the second drag frame, and the operation is also the same.

[0019] In a preferred embodiment, the sprinkler pipe valve switch is used to control the water flow rate in the sprinkler pipe, and the sprinkler pipe switch is used to control the on / off state of the sprinkler.

[0020] As a preferred embodiment, the laser positioning emission point is fixed to one side of the support frame. The laser positioning emission point can be set according to the laying requirements on the cast-in-place concrete by sensing the edge of the already laid plastic film. After setting the movement route, the start and stop device switch on the control switch operating platform is turned on. This allows the entire film-laying watering to move along the prescribed route. If it moves to the cast-in-place concrete without special reasons, the laser positioning emission point is set again and the movement continues to complete the film-laying curing.

[0021] As a preferred embodiment, the laser positioning emission point adopts intelligent film laying tracking technology, a non-contact tracking mode; by setting the laying position or near the edge of the plastic film, the equipment is guided to move and lay the plastic film and geotextile and sprinkle water, using the Xinlide AGV-2T model laser-guided automatic equipment for moving and laying.

[0022] As a preferred embodiment, the water tank is provided with a water tank inlet at the top, which facilitates the replenishment of water to the water tank.

[0023] A method of use for a membrane curing device suitable for large-volume concrete includes the following steps:

[0024] S1. Based on the actual situation of the cast-in-place concrete and the need for curing progress control in the project, first plan the specific route for laying, and then lay the route for the first time by using the laser positioning emission point; at the same time, fill the water tank with water in advance and fully charge the battery.

[0025] After the initial laser positioning emission point is reached and the edge of the cast-in-place concrete is reached, the subsequent laser positioning emission point can be set to the offset width of the previously laid line, i.e., the laser guidance is used to guide the equipment to move along the edge of the plastic film near the laid position to lay the plastic film and geotextile and sprinkle water.

[0026] S2. Place the equipment at the starting point of the cast-in-place concrete laying, place the plastic film on the first drag frame and the geotextile on the second drag frame, and open the control switch of the water spray pipe valve and the start and stop device switch on the control switch operating platform.

[0027] S3. Start the shut-off device switch on the control switch operation platform and set the start / stop device switch to a speed range of 1m / min for laying. Track and observe the laying process. When the equipment is laid to the edge of the cast-in-place concrete or at the joint, shut off the device switch on the control switch operation platform. At the same time, press the second cutting blade button to cut the plastic film and the second cutting blade switch to cut the geotextile, thus completing the curing of this section of the membrane.

[0028] S4. Move the device to the lower end of the membrane curing position, set the laser positioning emission point to the line that was laid last time, use the edge of the plastic film near the last laid position as the laser guide, parallel to the laying position, guide the device to move along, and at the same time start laying the plastic film and geotextile and sprinkling water.

[0029] During the installation process, the flow rate of the sprinkler pipe valve can be set at any time according to the water level in the water tank. At the same time, the operating handle of the rotating shaft of the positioning sprinkler head can be adjusted to drive the rotating shaft of the positioning sprinkler head to determine the rotation angle of the positioning sprinkler head, ensuring that the water from the sprinkler head meets the needs of curing and cooling.

[0030] Throughout the process, pay attention to replacing the plastic film and geotextile at any time, replenish the water in the water tank in a timely manner, control the laying speed and boundary cutting of the plastic film and geotextile in advance according to the laying length, and move to the laser positioning emission point of the next position.

[0031] S5. After the laying is completed, turn off the control switch, operate the platform and empty the water tank in time. Remove any unused plastic film and geotextile from the first and second drag frames in time for the next laying.

[0032] S6. During the next laying, repeat steps S1 to S5. At the same time, set the laying speed of different working sections according to the specific site conditions and monitor and adjust it in a timely manner to achieve control over the entire cast-in-place concrete.

[0033] In summary, the technical effects and advantages of this invention are as follows:

[0034] This invention relates to a membrane curing device and its application method for large-volume concrete. It can achieve both the function of moisturizing the surface of cast-in-place large-volume concrete by laying a membrane and the function of spraying water to cool and cure the surface of large-volume concrete by covering it with geotextile. Moreover, the membrane laying device can complete the process in one go, reducing the overall membrane curing operation process. At the same time, it reduces the possibility of temperature cracks caused by untimely curing of large-volume concrete and improves the curing effect of large-volume concrete.

[0035] This invention relates to a membrane curing device and its usage method for large-volume concrete. After the concrete is poured, the device can be used to lay plastic film, geotextile and sprinkle water. It does not need to wait until the concrete surface is safe for people to walk on. The entire laying process can be completed in one go, avoiding repeated walking and multiple operations. This can reduce the damage to the concrete caused by human factors and improve the quality of large-volume concrete.

[0036] This invention relates to a membrane curing device and its usage method for large-volume concrete. The entire operation can be completed by a single person on-site. It can quickly lay plastic film, geotextile and water on the surface of poured large-volume concrete in one go, achieving the effects of moisturizing and cooling the concrete surface. It has the effects of fully automatic, fast and precise control, saving a lot of manpower and time. Attached Figure Description

Detailed Implementation

[0042] 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.

[0043] Reference Figures 1-4 A device suitable for the curing of large-volume concrete membrane includes a first drag frame 14 for laying plastic film, a second drag frame 16 for laying geotextile, and a water spraying conduit valve 6 for water spraying. The water spraying conduit valve 6 can complete the entire operation process at once. The second drag frame 16 is equipped with cast-in-place concrete 1, and a water spraying position 18 is provided below the cast-in-place concrete 1.

[0044] The first cutting blade 15 is provided at the rear of the first towing frame 14, and the second cutting blade 17 is provided at the rear of the second towing frame 16. The water spray pipe valve 6, the first cutting blade 15 and the second cutting blade 17 are all controlled by the control switch operating platform 13.

[0045] The second towing frame 16 is equipped with a water spraying platform plate 3, and a water spraying pipe 7 is connected to the water spraying platform plate 3. A water tank 10 is connected to the water spraying pipe 7. A water tank inlet 8 is provided above the water tank 10 to facilitate water replenishment to the water tank 10. The four corners of the water tank 10 are welded to the support frame 9. The water tank 10 is fixed by the support frame 9. A storage battery 12 is installed at the bottom of the support frame 9, and a fixed control switch operating platform 13 is provided.

[0046] Below the battery 12 and the control switch operating platform 13, there is a track 11. A laser positioning emission point 19 is provided in the forward direction of the center of the track 11. The lower end of the water spraying pipe 7 is connected to the water spraying platform plate 3. The water spraying platform plate 3 is provided with multiple water spraying nozzles 2. The water spraying nozzle 2 includes a positionable water spraying nozzle 2-1. The positionable water spraying nozzle 2-1 is formed with a positionable water spraying nozzle rotation angle 2-3. The water spraying nozzle 2 sprays water on the surface of the cast-in-place concrete 1 to wet the geotextile and achieve the purpose of cooling. The water spraying nozzle 2 can be controlled by the positionable water spraying nozzle rotation shaft operating handle 2-4 and the water spraying pipe switch 13-4 to control the water spraying position 18.

[0047] The control switch operating platform 13 is equipped with a water pipe valve switch 13-1, a second die cutter button 13-2, a start / stop device switch 13-3, a water pipe switch 13-4, and a second die cutter switch 13-5. During the operation of the equipment, the switches on the control switch operating platform 13 can be pressed at any time as needed to achieve control. As the water pipe valve switch 13-1 and the start / stop device switch 13-3 move to the right, the water output of the water nozzle 2-1 increases, the power provided by the battery 12 increases, and the laying speed of the equipment increases.

[0048] The battery 12 is a traction battery, a liquid-charged battery with a voltage of 80V and a rated capacity of 560AH; it can provide power for the entire equipment and enable the entire equipment to be laid at a speed range of 0 to 5m / min, moving the entire track 11.

[0049] Track 11 measures 180mm×60mm×45mm and has a pitch of 60mm. It is made of three-strand rubber material with a length and width of 180mm. The maximum contact area of ​​track 11 avoids irreversible damage to the surface and interior of the cast-in-place concrete 1.

[0050] Water tank 10 and sprinkler head 2 are connected by sprinkler pipe 7. Sprinkler head 2 is parallel to the mulching direction on sprinkler platform plate 3. Sprinkler platform plate 3 is a steel plate with a length of 4000mm, a width of 500mm and a thickness of 50mm. It is equipped with a row of sprinkler head rotating shafts 2-2. The entire sprinkler platform plate 3 and water together have a certain weight, which can compact the laid plastic film and geotextile to achieve a tighter contact with the surface of cast-in-place concrete 1.

[0051] The two ends of a row of sprinkler heads 2 on the sprinkler platform plate 3 are respectively provided with a positioning sprinkler head rotating shaft operating handle 2-4, which can be rotated clockwise or counterclockwise, thereby driving the positioning sprinkler head rotating shaft 2-2 to rotate a certain angle, so as to realize the change of the positioning sprinkler head 2-1;

[0052] Simultaneously, the water pressure in the sprinkler pipe 7 is controlled by the sprinkler pipe valve 6 and the sprinkler pipe valve switch 13-1, ultimately achieving the purpose of changing the angle of the spray position 18. When the water is sprayed to the edge of the cast-in-place concrete 1 or to the already sprayed position, the sprinkler pipe valve 6 is closed and the water spraying stops after pressing the sprinkler pipe switch 13-4 on the control switch operating platform 13. When moving to the next spray position, the sprinkler pipe valve 6 is opened again after pressing the sprinkler pipe switch 13-4 on the control switch operating platform 13, and the water spraying begins.

[0053] The water-sprinkling platform 3 is a steel plate with a length of 4000mm, a width of 500mm, and a thickness of 50mm. It is equipped with a row of rotating shafts 2-2 for positioning water sprinkler heads. The entire water-sprinkling platform 3 has a certain weight along with the water, which can compact the laid plastic film and geotextile to achieve a tighter contact with the surface of the cast-in-place concrete 1.

[0054] The end of the second drag frame 16 is connected to the film-laying roller shaft 16-1. Bundles of geotextile 16-2 are provided on the film-laying roller shaft 16-1. Movable drag frame buckles 16-3 are provided at both ends of the film-laying roller shaft 16-1. An elastic tube 16-4 is provided above the second drag frame 16. As the geotextile is laid, the geotextile 16-2 rolls and is laid with the film-laying roller shaft 16-1. When it is laid to the edge of the cast-in-place concrete 1 or after leaving a certain overlap length with the already laid position, the second cutting blade switch 13-5 on the control switch operating platform 13 is pressed. The second cutting blade 17 on the second drag frame 16 for laying geotextile falls down. After the geotextile is cut, the second cutting blade 17 is raised.

[0055] As the geotextile is continuously laid on the second drag frame 16, when the geotextile is used up, press the start / stop device switch 13-3 on the control switch operating platform 13. After the device stops moving, forcefully open the movable drag frame buckle 16-3 at one end, load the geotextile 16-2 onto the film laying roller shaft 16-1, and then open the movable drag frame buckle 16-3 at this end. When the movable drag frame buckle 16-3 is opened, the elastic connecting pipe 16-4 has a spring inside and is wrapped with rubber of a certain stiffness on the outside. Under external force, the rubber and the internal spring will undergo a certain elastic displacement. When the load is removed, it can return to its original position under the action of the spring.

[0056] The operation of the first die-cutting blade 15 on the first drag frame 14 is the same as that of the second die-cutting blade 17 on the second drag frame 16, so it will not be described again.

[0057] Sprinkler pipe valve switch 13-1 is used to control the water flow speed of sprinkler pipe 7, and sprinkler pipe switch 13-4 is used to control the on / off of sprinkling;

[0058] When there is a lot of water in the water tank 10, the sprinkler pipe valve switch 13-1 moves to the right, increasing the amount of water entering the sprinkler head 2 from the water tank 10; when there is a little water in the water tank 10, the sprinkler pipe valve switch 13-1 moves to the left, decreasing the amount of water entering the sprinkler head 2 from the water tank 10; if it is necessary to close the sprinkler head 2, then close the sprinkler pipe switch 13-4.

[0059] The laser positioning emission point 19 is fixed to one side of the support frame 9. The laser positioning emission point 19 can move along the prescribed route by sensing the edge of the already laid plastic film according to the laying requirements on the cast-in-place concrete 1. After turning on the start and stop device switch 13-3 on the control switch operating platform 13, the entire film laying and watering can be moved along the prescribed route. If there is no special reason for moving to the cast-in-place concrete 1, the laser positioning emission point 19 is set again to continue moving and complete the film laying and curing. The laser positioning emission point 19 adopts intelligent film laying tracking technology and non-contact tracking mode. By setting the laying position or the edge of the plastic film, the equipment is guided to move and lay the plastic film and geotextile and water along the edge. The Xinlide AGV-2T model laser-guided automatic equipment is used for moving and laying.

[0060] A method of use for a membrane curing device suitable for large-volume concrete includes the following steps:

[0061] S1. Based on the actual situation of the cast-in-place concrete 1 in the project and the need for curing progress control, first plan the specific route for laying, and first lay the position route through the laser positioning emission point 19; at the same time, fill the water tank 10 with water in advance and fully charge the battery 12.

[0062] After the initial laser positioning emission point 19 is established and reaches the edge of the cast-in-place concrete 1, the subsequent laser positioning emission point 19 can be set to the offset width of the previously laid line, i.e., the laser guidance is used to guide the equipment to move along the edge of the plastic film near the laid position and to lay the plastic film and geotextile and sprinkle water.

[0063] S2. Place the equipment at the starting point of the cast-in-place concrete 1, place the plastic film on the first drag frame 14, and the geotextile on the second drag frame 16. Open the control switch 13-1 of the water spray pipe valve 6 and the start and stop device switch 13-3 on the control switch operation platform 13.

[0064] S3. Start the closing device switch 13-3 on the control switch operation platform 13. Set the start and closing device switch 13-3 to a speed range of 1m / min for laying. Track and observe the laying process. When the equipment lays to the edge or joint of the cast-in-place concrete 1, turn off the device switch 13-3 on the control switch operation platform 13. At the same time, press the second cutting blade button 13-2 to cut the plastic film and the second cutting blade switch 13-5 to cut the geotextile, thus completing the curing of this section of the membrane.

[0065] S4. Move the device to the lower end of the membrane curing position, set the laser positioning emission point 19 to the line that was laid last time, use the edge of the plastic film near the last laid position as the laser guide, parallel to the laying position, guide the device to move along, and at the same time start laying the plastic film and geotextile and sprinkling water.

[0066] During the laying process, the flow rate of the sprinkler pipe valve switch 13-1 can be set at any time according to the water status of the water tank 10. At the same time, the operating handle 2-4 of the positioning sprinkler head rotating shaft can be adjusted to drive the positioning sprinkler head rotating shaft 2-2 to determine and control the rotation angle 2-3 of the positioning sprinkler head, so as to ensure that the water of the sprinkler head 2 meets the needs of curing and cooling.

[0067] Throughout the process, pay attention to replacing the plastic film and geotextile at any time, replenish the water in the water tank in a timely manner, control the laying speed and boundary cutting of the plastic film and geotextile in advance according to the laying length, and move to the laser positioning emission point 19 in the next position.

[0068] S5. After the laying is completed, turn off the control switch on the operating platform 13 and empty the water tank 10 in time. Remove the unused plastic film and geotextile from the first drag frame 14 and the second drag frame 16 in time for the next laying.

[0069] S6. During the next laying, repeat steps S1 to S5. At the same time, set the laying speed of different working sections according to the specific site conditions and monitor and adjust it in a timely manner to achieve control over the entire cast-in-place concrete 1.

Move the device to the lower end of the membrane curing position, set the laser positioning emission point (19) to the line that was laid last time, use the edge of the plastic film near the last laid position as the laser guide, parallel to the laying position, guide the device to move along, and at the same time start laying plastic film and geotextile and sprinkling water. During the laying process, the flow rate of the sprinkler pipe valve switch (13-1) can be set at any time according to the water condition of the water tank (10). At the same time, the operating handle (2-4) of the positioning sprinkler head rotating shaft is adjusted to drive the positioning sprinkler head rotating shaft (2-2) to determine the control angle (2-3) of the positioning sprinkler head rotation, so as to ensure that the water in the sprinkler head (2) meets the needs of curing and cooling. Throughout the process, pay attention to replacing the plastic film and geotextile at any time, replenish the water in the water tank in time, control the laying speed and boundary cutting of the plastic film and geotextile in advance according to the laying length, and change to the laser positioning emission point (19) of the lower position. S5. After the laying is completed, turn off the control switch operating platform (13) and empty the water tank (10) in time. Take out the unused plastic film and geotextile from the first drag frame (14) and the second drag frame (16) in time for the next laying. S6. Repeat steps S1 to S5 during the next laying. At the same time, set the laying speed of different working sections according to the specific site conditions and monitor and adjust it in a timely manner to achieve control over the entire cast-in-place concrete (1).
