Description

Technical Field

[0001] The invention relates to the technical field of water conservancy and civil engineering, and in particular to a concrete formwork with water-passing, temperature-reducing and crack-preventing functions and a construction method thereof. Background Art

[0002] Concrete formwork (slope protection board made of concrete) refers to prefabricated concrete components used to construct slope protection structures in water conservancy civil engineering projects. River slope protection in water conservancy projects usually has specific shape and size requirements, such as slope, length and height. The use of concrete formwork can effectively constrain the shape and size of the river channel and ensure the smooth flow of water. At the same time, concrete formwork has high strength and hardness, can effectively resist the scouring of water flow, and protect the river bank from erosion.

[0003] Existing, such as Chinese patent publication number: CN114164796B, discloses a concrete slope protection structure, including a base, a rotating member and a panel; in the invention, the rotating member is first installed in the groove of the base, and then the prefabricated base is fixed at the position of the slope foot, and finally the panel is stacked and installed layer by layer. Since the panel and the rotating member are plug-in, and the rotating member and the base are in a rotatable connection, the panel can be rotated at a certain angle, and the angle between the panel and the bottom surface of the base can be changed, so that the slope protection structure can be used on slopes of different angles, thereby increasing the scope of use of the slope protection structure. At the same time, since all components of the slope protection structure including the base and the panel are prefabricated components, the maintenance of the slope protection on site is reduced, and the production of the slope protection components and the repair of the slope can be carried out simultaneously, thereby shortening the construction period of the slope protection and improving the construction efficiency.

[0004] Although the concrete slope protection structure in the above-mentioned patent shortens the construction period of slope protection and improves the efficiency of construction, after the concrete formwork is constructed into a slope protection in the river channel, during long-term use, the water level in the river channel will fluctuate due to the season and weather. When the weather is dry, the water level will continue to drop, and most of the concrete formwork constituting the slope protection will be exposed to the air, and only a small part below the water level of the river channel will be soaked. The surface temperature of the exposed part will rise after being exposed to the sun, and the internal moisture will be evaporated, which will cause the concrete formwork to expand, and there will be differences in the temperature changes inside and outside, which will lead to inconsistent expansion of the concrete formwork inside and outside and generate stress. When this stress exceeds the tensile strength of the concrete formwork material, it will cause cracking. This problem seriously threatens the service life and use effect of the concrete formwork in the application of river slope protection.

[0005] Therefore, we propose a concrete formwork with water cooling and crack prevention effects and a construction method thereof, in order to solve the above-mentioned problems. Summary of the invention

[0018] S2, after the first concrete slab and the second concrete slab form a completed concrete formwork, the water channels, transverse channels, overflow channels and water injection ports in the first concrete slab and the second concrete slab are connected;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1.

The input end and output end of the water pump 208 are respectively fixedly connected with a water pumping pipe 209 and a water injection pipe 210 extending downward. The bottom end of the water injection pipe 210 is fixedly connected to the front surface of the second concrete slab 106 and is connected to the water injection port 110. The bottom end of the water pumping pipe 209 is surrounded by a plurality of longitudinal grooves and is 10 cm higher than the bottom of the second concrete slab 106. The outer surfaces of the water pumping pipe 209 and the water injection pipe 210 both penetrate the inner bottom of the installation frame 202. The inner part of the first concrete slab 101 near the two top corners are embedded with There is a connecting sleeve 105, and two fastening bolts 107 are arranged on the front surface of the second concrete plate 106. The rear end of the fastening bolt 107 is threadedly connected to the inner wall of the connecting sleeve 105. The bottom of the first concrete plate 101 is symmetrically provided with a slot 104 whose height is less than the height of the first concrete plate 101. The rear surface of the second concrete plate 106 is symmetrically fixedly connected with an insertion strip 109 whose height is less than the height of the second concrete plate 106 near the bottom, and the insertion strip 109 and the slot 104 are plug-in connected. A plurality of cross-shaped special-shaped nails 111 are arranged and fixedly connected on the rear surface of the first concrete plate 101.

[0041] In this embodiment, when constructing the device to form a river slope protection for a water conservancy project, the prefabricated first concrete slab 101 and the second concrete slab 106 are assembled, and the second concrete slab 106 is first placed on the surface of the first concrete slab 101, and then the insert 109 is inserted into the slot 104 by pushing so that the two form a complete concrete template. At this time, the water groove 102, the transverse groove 103, the overflow groove 108 and the water injection port 110 in the first concrete slab 101 and the second concrete slab 106 are connected, and then the fastening bolt 107 is inserted into the slot 104. After the end passes through the second concrete slab 106, it is threadedly connected with the connecting sleeve 105 embedded in the first concrete slab 101, thereby completing the assembly of the concrete template. Subsequently, the multiple concrete templates are hoisted to the river slope protection position in sequence by hoisting, and then arranged in sequence and connected to the adjacent concrete templates by concrete pouring. When the river slope protection formed by the device encounters continuous drought weather and causes the river water level to drop to a certain level, the water pump 208 is started to extract water from the river through the pumping pipe 209, and the water is pumped out through the water injection pipe 210. It is injected into the water injection port 110, and the water will enter the S-shaped water groove 102 inside the concrete formwork, thereby effectively replenishing the maintenance moisture of the concrete formwork. With the injection of river water, when the water inside the water groove 102 and the transverse groove 103 is filled, it will flow out from the surface of the second concrete slab 106 through the overflow groove 108, thereby replenishing moisture to the exposed surface and cooling it down. The design of internal water flow effectively solves the problem of cracking of the concrete formwork in the river slope protection due to exposure to the sun, and improves the use of the concrete formwork in the river slope protection application At the same time, in daily conditions, the bottom of the baffle 301 is close to the water level of the river, and its body will shield the second concrete slab 106, thereby shielding the sunlight and slowing down the cracking of the part of the concrete formwork exposed above the water level due to water loss. The special-shaped nails 111 are cast into a whole with the first concrete slab 101. When the rear surface of the first concrete slab 101 is fitted with the soil on the side of the river, the cross-shaped special-shaped nails 111 will be embedded in the soil, thereby improving the stability of the concrete formwork.

[0042] Embodiment 2: Figure 1-Figure 4 and Fig.11As shown, a motor 206 with the output end facing right is installed near the middle of the inner bottom of the installation frame 202, and the outer surfaces of both sides of the installation frame 202 are rotatably connected with connecting shafts 204 through bearings, and one end of the connecting shaft 204 extends to the inside of the installation frame 202, and a gear column 205 is fixedly installed between the ends of the two connecting shafts 204 through a flange, and the opposite ends of the two connecting shafts 204 are provided with flanges for connection, and the output end of the motor 206 is fixedly connected with a driving gear 206 meshing with the outer surface of the gear column 205. 07. The front surface of the mounting frame 202 is symmetrically fixedly connected with slide bars 203 near the edges on both sides. The water-blocking mechanism 3 includes a water-blocking plate 301 for water-blocking. The water-blocking plate 301, the first concrete plate 101 and the second concrete plate 106 are of the same size. The rear surface of the water-blocking plate 301 is symmetrically provided with slide grooves 302 near the edge. The rear surface of the water-blocking plate 301 is provided with a groove 303 near the middle position. The front inner surface wall of the groove 303 is provided with teeth 304, and the teeth 304 are meshed and connected with the outer surface of the tooth column 205.

[0043] In this embodiment, when the river water level is high for a long time during the rainy season, long-term immersion will cause moisture to penetrate into the interior through the tiny pores on the surface of the second concrete slab 106 for a long time, reducing the strength and durability of the concrete. In addition, long-term immersion under high water conditions will also cause the corrosive substances in the water, such as chloride ions, to accelerate the corrosion of the steel bars inside the concrete and destroy the concrete formwork structure. In this case, the motor 206 in the installation frame 202 can be started to drive the drive gear 207 to rotate. At this time, the drive gear 207 will drive the gear column 205 to rotate. When the gear column 205 rotates, under the action of the meshing teeth 304, it converts the power in the rotation direction into the power of linear motion. The baffle 301 is limited by the slide groove 302 and the slide bar 203 and can only be raised and lowered. Therefore, the baffle 301 will move downward and be inserted into the bottom of the river, thereby making The position between the baffle plate 301 and the second concrete plate 106 forms a separation zone with a narrow front-to-back distance. At this time, the water in the river channel is blocked by the baffle plate 301. When the sunlight is strong during the day, the water pump 208 is started to circulate the water in the separation zone and discharge it back into the separation zone through the water trough 102. During the process, the water level in the separation zone can be gradually controlled under the absorption of the first concrete plate 101 and the second concrete plate 106 and the evaporation caused by temperature, thereby avoiding the problem of damage caused by long-term immersion of the concrete formwork in high water levels over a large area, further improving the service life and use effect of the concrete formwork in the river channel of the water conservancy project. The adjacent concrete formworks can connect the adjacent connecting shafts 204 through bolts and flanges, so that one motor 206 can drive multiple gear columns 205 to rotate, reducing the number of electrical components and reducing costs.

[0044] Embodiment 3: Figure 1-Figure 4 and Figure 8-Figure 11As shown, the reciprocating mechanism 4 includes two connecting seats 401 fixed on the front surface of the second concrete plate 106, and a rotating shaft 402 with two ends extending outward is rotatably connected between the outer surfaces of the two connecting seats 401 through bearings. The length of the rotating shaft 402 is smaller than the width of the second concrete plate 106, and a transmission gear 403 is fixedly connected to the outer surface of the rotating shaft 402 near the middle position. The outer surface of the transmission gear 403 is meshed with the teeth 304, and the two ends of the rotating shaft 402 are fixedly connected to the swing rod 404. The first rotating pin 405 is installed near the bottom of the outer surface of the opposite side of the two swing rods 404, and the outer surfaces of the two first rotating pins 405 are rotatably connected to the connecting rod 406. The cleaning mechanism 5 includes two fixed A fixed rail 503 is connected to the front surface of the second concrete slab 106, and the two fixed rails 503 are located below the connecting seat 401. The front surfaces of the two fixed rails 503 are slidably connected to the sliding rails 502. A U-shaped outer recessed frame 501 is fixedly connected between the front surfaces of the two sliding rails 502. The surface of the outer recessed frame 501 is provided with a plurality of rectangular grooves that penetrate therethrough at equal intervals, and the rear surface of the outer recessed frame 501 is fixedly connected with a plurality of brushes 505 that are staggered with the positions of the rectangular grooves at equal intervals. The rear surface of the brushes 505 is tightly fitted to the front surface of the second concrete slab 106. Second rotating pins 504 are symmetrically installed on the outer surfaces of both sides of the outer recessed frame 501, and the two second rotating pins 504 are rotatably connected to the bottom ends of the two connecting rods 406 respectively.

[0045] In this embodiment, the transmission gear 403 which forms a rotational connection with the second concrete plate 106 through the mounting seat 401 and the rotating shaft 402 is meshed with the teeth 304 in the groove 303 on the surface of the watertight plate 301, and the outer recessed frame 501 can only move up and down on the front side of the second concrete plate 106 through the cooperation of the sliding rail 502 and the fixed rail 503. Therefore, when the watertight plate 301 is lifted or lowered, the transmission gear 403 will rotate synchronously and drive the rocker arms 404 at both ends to rotate through the rotating shaft 402. At this time, the first rotating pin 405 and the The top end of the connecting rod 406 connected to the far end of the swing rod 404 will make a circular motion with the rotating shaft 402, and the bottom end of the connecting rod 406 will pull the outer recessed frame 501 below to reciprocate up and down. At this time, the brush 505 made of polypropylene material on the rear side of the outer recessed frame 501 will scrape the surface of the second concrete slab 106 up and down, preventing impurities and microorganisms in the water from adhering to and growing on the surface of the concrete formwork and causing additional pressure and clogging the surface micropores, thereby improving the use effect of the concrete slab. The design structure is reasonable, does not require an additional power source, and has the effect of saving resources.

[0046] In the present invention, when constructing the device to form a river slope protection for a water conservancy project, the prefabricated first concrete slab 101 and the second concrete slab 106 are assembled, and the second concrete slab 106 is first placed on the surface of the first concrete slab 101, and then the insert 109 is inserted into the slot 104 by pushing so that the two form a complete concrete template. At this time, the water trough 102, the transverse groove 103, the overflow groove 108 and the water injection port 110 in the first concrete slab 101 and the second concrete slab 106 are connected, and then the end of the fastening bolt 107 is passed through the second concrete slab 106 and is threadedly connected to the connecting sleeve 105 embedded in the first concrete slab 101, thereby completing the assembly of the concrete template, and then the plurality of concrete slabs are hoisted. After the concrete formworks are hoisted to the river slope protection position in sequence, they are arranged in sequence and the adjacent concrete formworks are connected into a whole by pouring concrete. When the river slope protection formed by the device encounters continuous drought weather and causes the river water level to drop to a certain level, the water pump 208 is started to extract water from the river through the pumping pipe 209, and the water is injected into the water injection port 110 through the water injection pipe 210. At this time, the water will enter the S-shaped water trough 102 inside the concrete formwork, thereby effectively replenishing the maintenance moisture of the concrete formwork. With the injection of river water, when the water inside the water trough 102 and the transverse groove 103 is filled, it will flow out from the surface of the second concrete slab 106 through the overflow groove 108, thereby replenishing moisture to the exposed surface and cooling it down. The design of partial water permeability effectively solves the problem of cracking of concrete formwork in river slope protection due to exposure to the sun, and improves the service life and use effect of concrete formwork in river slope protection applications. At the same time, in daily conditions, the bottom of the baffle 301 is close to the water level of the river, and its body will shield the second concrete slab 106, thereby shielding the sunlight and slowing down the cracking of the part of the concrete formwork exposed above the water level due to water loss. In addition, when the water level of the river is high for a long time during the rainy season, long-term immersion will cause moisture to penetrate into the interior through the tiny pores on the surface of the second concrete slab 106 for a long time, reducing the strength and durability of the concrete. In addition, long-term immersion under high water conditions will also cause water erosion. In this case, the motor 206 in the mounting frame 202 can be started to drive the driving gear 207 to rotate. At this time, the driving gear 207 will drive the tooth column 205 to rotate. When the tooth column 205 rotates, the tooth 304 meshing with it converts the power of the rotation direction into the power of linear motion. The baffle 301 is limited by the slide groove 302 and the slide bar 203 and can only be raised and lowered. Therefore, the baffle 301 will move downward and be inserted into the bottom of the river channel, thereby forming a narrow separation zone between the baffle 301 and the second concrete slab 106. At this time, the water in the river channel is blocked by the baffle 301. When the sunlight is strong during the day,Start the water pump 208 to circulate the water in the separation area and re-discharge it into the separation area through the water trough 102. During the process, the water level in the separation area can be gradually controlled under the absorption of the first concrete slab 101 and the second concrete slab 106 and the evaporation caused by temperature, thereby avoiding the problem of damage to the concrete formwork caused by long-term immersion in high water levels over a large area, further improving the service life and use effect of the concrete formwork in the river channel of the water conservancy project, and the transmission gear 403 that forms a rotational connection with the second concrete slab 106 through the mounting seat 401 and the rotating shaft 402 is simultaneously meshed with the teeth 304 in the groove 303 on the surface of the water-blocking plate 301, and the outer recessed frame 501 can only be moved in front of the second concrete slab 106 through the cooperation of the sliding rail 502 and the fixed rail 503. The side moves up and down, so when the water baffle 301 is in the process of lifting, the transmission gear 403 will rotate synchronously, and drive the swing rod 404 at both ends to rotate through the rotating shaft 402. At this time, the top of the connecting rod 406 connected to the far end of the swing rod 404 through the first rotating pin 405 will make a circular motion with the rotating shaft 402, and the bottom of the connecting rod 406 will pull the outer recessed frame 501 below to reciprocate up and down. At this time, the brush 505 made of polypropylene material on the rear side of the outer recessed frame 501 will scrape the surface of the second concrete plate 106 up and down to prevent impurities and microorganisms in the water from attaching and growing on the surface of the concrete formwork and causing additional pressure and clogging the surface micropores, thereby improving the use effect of the concrete plate. The design structure is reasonable, does not require an additional power source, and has the effect of saving resources.
