Description

Technical Field

[0001] This invention relates to an integrated bottom plate with a hollow L-shaped prefabricated revetment. Background Technology

[0002] Traditional cast-in-place reinforced concrete revetments face numerous challenges in long-distance, large-scale construction and underwater construction, making it difficult to guarantee the quality of the revetment; the construction process is complex and the construction period is long; the construction site requires a large area to store construction materials, occupying a large amount of scarce temporary land; and the construction site is characterized by extensive management, chaos, and low efficiency.

[0003] Prefabricated revetments are constructed in factories and installed on-site, improving on-site construction efficiency, reducing water pollution during construction, and being environmentally friendly. However, due to the lack of clear indicators for existing prefabricated technologies in water conservancy and water transport, and the limited practical application and research of prefabricated structures in my country's water conservancy industry, the application of prefabricated structures in revetment projects is relatively backward. For example, when revetments are laid along riverbanks, the soil is mostly silt with poor bearing capacity, and prefabricated revetments are heavy, requiring high standards for transportation vehicles and roads. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated base plate with a hollow L-shaped prefabricated revetment, which can effectively solve the problems of heavy weight and high requirements for transportation vehicles and roads in the prior art.

[0005] The technical solution to achieve the above objectives is: an integral base plate with a hollow L-shaped prefabricated revetment, including a revetment body, the revetment body being L-shaped, the revetment body including a base plate and a breast plate that are perpendicular to each other and integrally formed, the base plate having a hollow-shaped inner cavity, the inner cavity having a dense steel mesh, and the outer side of the dense steel mesh having a concrete slab.

[0006] Preferably, the breast plate has Z-shaped construction guide grooves on both sides, and the bottom plate and the upper surface of the breast plate have reserved gaps.

[0007] Preferably, the base plate and the breast plate are connected by an angle plate, and the angle plate is L-shaped.

[0008] Preferably, the end faces of the base plate and the breast plate are provided with two threaded holes, and lifting rings are threaded into the multiple threaded holes. A level bubble meter is placed at each of the four corners of the upper surface of the base plate.

[0009] Preferably, the connection between the base plate and the breast plate is provided with a trapezoidal angle that turns from 90 degrees to 45 degrees.

[0010] Preferably: the upper surface of the base plate is connected to a guide rail, the guide rail is close to the chest plate, the upper surface of the guide rail is movably connected to a support plate, the inner ends of the chest plate are provided with first sliding grooves, one end of a push rod is movably connected in the two first sliding grooves, the other end of the two push rods is connected to the lower surface of the lifting plate, the lifting plate is L-shaped, the lower surface of the lifting plate is connected to an inclined plate, the inclined plate is away from the push rod, and the lower part of the inclined plate contacts the support plate.

[0011] Preferably, the upper surface of the lifting plate is provided with a second sliding groove, and a scraper box is movably connected in the second sliding groove. The shape of the scraper box matches the shape of the lifting plate. A scraper is movably connected in the scraper box, and a scraper strip is provided on the scraper. Multiple springs are provided between the scraper and the scraper box.

[0012] Preferably, the breast plate has a first mounting block and a second mounting block at its two ends, the side of the first mounting block is movably connected to one end of a screw, the other end of the screw passes through the side of the second mounting block and is connected to a motor, the surface of the screw is threadedly connected to a moving block, the upper surface of the moving block is provided with a movable rod, and the other end of the movable rod passes through the surface of the scraper box.

[0013] Preferably, the support plate is connected to the movable block by screw threads.

[0014] Preferably, the lower end of the scraper box is provided with a scraper, which is made of stainless steel.

[0015] Technical effects of the present invention:

[0016] 1) This technical solution is lighter than ordinary prefabricated structures because the base plate has a U-shaped inner cavity, thereby reducing transportation and hoisting costs, reducing the load-bearing capacity of the temporary road surface at the site, and reducing the restrictions on equipment operating conditions.

[0017] 2) Due to the lighter base plate, the overall center of gravity of the component changes. During transportation, the wall is laid flat, and the height of the wall is lower than the width of the base plate, thereby reducing the width occupied by the road and significantly reducing the area occupied by the road.

[0018] 3) It is applicable to projects with various types of pile foundations, without being limited by the type of pile foundation, and does not require on-site adjustment of the pile head reinforcement and revetment reinforcement, allowing it to be directly installed on-site;

[0019] 4) The U-shaped inner cavity reduces the difficulty of on-site concrete pouring, eliminating the need for formwork installation. Concrete can be poured directly into the inner cavity, thereby speeding up the pouring process and improving construction efficiency. At the same time, the interlocking between the poured concrete and the revetment is enhanced, resulting in a more stable overall structure and improved quality. Attached Figure Description

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] Please see Figure 1-4 Example 1:

[0032] The present invention relates to an integral base plate L-shaped prefabricated revetment with a U-shaped cavity, comprising a revetment body 1, which is L-shaped. The revetment body 1 includes a base plate 101 and a breast plate 102, which are perpendicular to each other and integrally formed. The base plate 101 has a U-shaped inner cavity 6, which contains a dense steel mesh 7. The breast plate 102 has Z-shaped construction guide grooves 111 on both sides, which facilitate the subsequent assembly of the revetment body 1. The upper surfaces of the base plate 101 and the breast plate 102 have reserved gaps 112. An angle plate 8 is connected to the outer surface of the base plate 101 and the breast plate 102, i.e., one end of the angle plate 8 is connected to the base plate 101, and the other end of the angle plate 8 is connected to the breast plate 102. The angle plate 8 is L-shaped, thereby increasing the overall stability of the revetment body 1 and preventing the revetment body 1 from being damaged during operation. Cracks occur during transport. A concrete slab is installed on the outer side of the dense steel mesh 7. Two threaded holes 2 are provided on the end faces of the bottom plate 101 and the breast plate 102. Lifting rings 3 are threaded into multiple threaded holes 2. The lifting rings 3 on the end face of the bottom plate 101 can be leveled by a hand-operated hoist 4. The hand-operated hoist 4 is used to level the revetment body 1. The hoisting operation is carried out after the revetment body 1 is leveled. A level bubble meter 5 is placed at each of the four corners of the upper surface of the bottom plate 101. The level of the bottom plate 101 is determined by observing the bubble positions of the four level bubble meters 5. The connection between the bottom plate 101 and the breast plate 102 is provided with a trapezoidal angle 113 that turns from 90 degrees to 45 degrees. At the same time, a back-adhesive waterstop is used on the inner side of the revetment body 1 to fill the original reserved gap. The water-facing side is filled with sealant to ensure waterproofing.

[0033] Working principle:

[0034] Example 1: Please refer to Figure 1-4

[0035] Square piles are driven into the ground on the riverbank to form the foundation. The upper surface of the square piles is treated with a concrete cushion layer, followed by pile chiseling. Meanwhile, the revetment body 1 is prefabricated as a whole. The outer formwork is supported by steel molds, the inner cavity 6 is made of customized steel membrane, and the inside is sealed with dense steel mesh 7. The conflict position with the pile head reinforcement is determined, and the spacing of the bottom plate reinforcement mesh is adjusted appropriately during prefabrication to avoid reinforcement conflict. During transportation, the wall is laid flat to reduce the width of the footprint until the revetment body 1 is transported to the square pile. A crane is used to lift the revetment body 1 onto the square pile.

[0036] First, connect the corner plate 8 to the breast plate 102 and the base plate 101 to increase the overall stability of the revetment body 1 and prevent cracks from forming during transportation. Connect the lifting rings 3 with straps and adjust the two lever hoists 4 to level the revetment body 1. After the revetment body 1 is leveled, the hoisting operation can be carried out. To make the revetment body 1 level, a level bubble meter 5 can be placed around the base plate 101 to improve the level accuracy of the base plate 101.

[0037] When lifting components, the "333 system" is followed. First, the prefabricated revetment body 1 is lifted to a position 300mm above the ground and held steady for 30 seconds. Relevant personnel must confirm that the revetment body 1 is level. After confirmation, lifting can continue. All personnel must stay at least 3 meters away from the revetment body. When the revetment body 1 is close to the fixture, it is slowly lowered. The lifting personnel use the fixture pulleys to assist in the lifting. Using the control lines on the ground, the revetment body 1 is kept as close to the edge line as possible. The positioning fixture is fixed to the cushion layer with expansion bolts along the edge line of the revetment. When the revetment body 1 is lifted to a height of 500mm above the surface of the cushion layer, it is placed close to the positioning angle plate. After slowly lowering, during the subsequent installation of the revetment body 1, the outer edge line and control line of the revetment are also marked on the cushion layer, and the positioning fixture is fixed on the breast plate side. During hoisting, the subsequent revetment body 1 is hoisted into place using the guiding action of the guide groove 111 and the limiting action of the positioning fixture. After the revetment is hoisted into place, concrete is poured into the inner cavity 6. At this time, the inner cavity 6 is the formwork for the concrete, and it can be poured directly. The gap between the bottom plate 101 and the cushion layer can be treated by grouting with waterproof mortar or by formwork. The inner side of the revetment body 1 is fitted with a back-adhesive waterstop, which is inserted into the original reserved gap 112. The water-facing side is filled with sealant.

[0038] Please see Figure 5-8 Example 2:

[0039] The upper surface of the base plate 101 is connected to the guide rail 10, which is close to the chest plate 102. The upper surface of the guide rail 10 is movably connected to the support plate 11. The inner sides of the chest plate 102 are provided with first sliding grooves 21 at both ends. The first sliding grooves 21 are T-shaped grooves. One end of the push rod 22 is movably connected in the two first sliding grooves 21. The other end of the two push rods 22 is connected to the lower surface of the lifting plate 18. The lifting plate 18 is L-shaped. The lower surface of the lifting plate 18 is connected to the inclined plate 23, which is away from the push rod 22. The lower part of the inclined plate 23 contacts the support plate 11. The upper part of the support plate 11 is provided with an inclined surface that matches the inclined plate 23. The upper surface of the lifting plate 18 is provided with a second sliding groove 24. The scraper box 20 is movably connected in the second sliding groove 24. The shape of the scraper box 20 matches the shape of the lifting plate 18. The scraper 27 is movably connected in the scraper box 20. The scraper 27 is provided with a scraper strip 26. Multiple springs 28 are provided between the scraper 27 and the scraper box 20. Under the elastic action of the multiple springs 28, the scraper strip 26 can better fit the outer side of the breast plate 102. The two ends of the breast plate 102 are respectively provided with a first mounting block 12 and a second mounting block 13. The side of the first mounting block 12 is movably connected to one end of a screw 15. The other end of the screw 15 passes through the side of the second mounting block 13 and is connected to a motor 14. The surface of the screw 15 is threadedly connected to a moving block 25. The upper surface of the moving block 25 is provided with a movable rod 17. The other end of the movable rod 17 passes through the surface of the scraper box 20. The support plate 11 is threadedly connected to the moving block 25 by screws 16. The lower end of the scraper box 20 is provided with a scraper 19. The scraper 19 is made of stainless steel to prevent the scraper 19 from rusting, thereby reducing the scraping performance of the scraper 19.

[0040] Example 2:

[0041] Please see Figure 5-8

[0042] When there is a lot of rain in summer, the water level in the river channel is higher than the height of the breast plate 102, which will cause backflow. At this time, the motor 14 is started. The output end of the motor 14 drives the screw 15 to rotate. The thread on the surface of the screw 15 drives the moving block 25 to move to the right. The moving block 25 drives the screw 16 and the movable rod 17 to move to the right. The screw 16 drives the support plate 11 to move to the right. The support plate 11 moves to the right on the surface of the guide rail 10. The support plate 11 drives the inclined plate 23 to move upward. The inclined plate 23 drives the lifting plate 18 to move upward. The lifting plate 18 drives the push rod 22 and the scraper box 20 to move upward. While moving upward, the scraper box 20 moves in the second sliding groove 24 under the action of the movable rod 17 until the lifting plate 18 rises higher than the water level in the river channel. Then the motor 14 is turned off and the lifting plate 18 stops rising, thus avoiding the backflow of river water.

[0043] When the scraper box 20 moves, the spring 28, under its own elastic force, keeps the scraper strip on the scraper 27 pressed against the outer surface of the lifting plate 18. The outer surface of the lifting plate 18 can be cleaned while the scraper box 20 is moving. Alternatively, when the lifting plate 18 is in the lowest position, the screw 16 can be removed and the motor 14 can be started. At this time, the lifting plate 18 will not rise, and the scraper box 20 will move left and right under the action of the movable rod 17. The movable rod 17 will move left and right under the action of the moving block 25, thereby facilitating the scraper 27 to clean the outer surface of the lifting plate 18.
