DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0038] Embodiment one: please refer to Figure 1 Figure 10 The present application provides a technical solution: a support frame for prefabricating water scattering, comprising a support frame 100 and a pouring carrier plate 102 arranged inside for prefabricating water scattering, a plurality of lifting holes 101 are formed on one side of the support frame 100, the pouring carrier plate 102 is arranged to prefabricate water scattering, and the plurality of lifting holes 101 are arranged to facilitate transportation of the prefabricated water scattering.

[0039] The support framework pipe 200 is uniformly arranged in the support frame 100 and is fixedly connected with the pouring carrier plate 102 for supporting the prefabricated water scattering, the support framework pipe 200 is internally hollow, and the inner pipe 201 passes through the inside of the support framework pipe 200, the ground plug 202 is arranged at both ends of the inner pipe 201, the ground plug 202 is designed in a conical spiral shape, the outer thread is mechanically engaged with the soil, and the inner hole is divided into two layers: the upper layer stores zinc particles, and the lower layer is a reaction cavity, and the top of the ground plug 202 is provided with a plurality of connecting top plates 207 which are bolted to the bottom of the support frame 100, and the inside of the inner pipe 201 is provided with a self-supplementing assembly for adjusting the position of the connecting top plate 207 according to the settlement inclination angle, the support framework pipe 200 is arranged to support the prefabricated water scattering and improve the strength, the ground plug 202 supports the support frame 100 to improve the strength and prevent settlement, and the plurality of ground plugs 202 are symmetrically arranged with the center of the support frame 100, which can adjust the flatness of the support frame 100 when the support frame 100 is settled, and the ground plug 202 cooperates with the self-supplementing assembly to detect the inclination of the support frame 100, so as to move the connecting top plate 207 and adjust the height of the support frame 100. ​

[0040] Further, the self-supplement assembly includes an acid storage shell 203 fixedly connected to the inside of the inner tube 201, an acid discharge groove 206 is arranged in the acid storage shell 203, and sulfuric acid is stored in the acid discharge groove 206, and the acid discharge groove 206 is configured as a plane, the inside of the ground plug 202 is provided with zinc metal, the top of the ground plug 202 is fixedly connected with a plurality of air cylinders 208, and the top of the plurality of air cylinders 208 is slidably connected with a piston rod 209 fixedly connected with the connecting top plate 207. By arranging the acid storage shell 203 at both ends of the support frame 100, the inclination of the support frame 100 can be sensitively detected. The acid discharge groove 206 is symmetrically arranged, so that when the acid storage shell 203 at one end is in conflict, the acid discharge groove 206 at the other end will not release the sulfuric acid inside, so that the zinc metal in the ground plug 202 at the low place mixes with the sulfuric acid to generate gas, so that the gas pushes the connecting top plate 207 to move upward, thereby driving one end of the support frame 100 to move upward, thereby adjusting the inclination of the support frame 100. A plurality of connecting top plates 207 are arranged at the top of the ground plug 202 and fixedly connected with the bottom of the support frame 100 by bolts, forming a reliable force transmission interface. A plurality of ground plugs 202 are symmetrically arranged with the geometric center of the support frame 100 as the reference, to ensure balanced force and provide a mechanical basis for subsequent differential adjustment of asymmetric settlement.

[0041] Specifically, the acid discharge groove 206 stores sulfuric acid, and the inside of the ground plug 202 stores zinc metal. When the support frame 100 settles and the two ends are not at the same level, the acid storage shell 203 will tilt so that the acid storage shell 203 at the low place tilts and the sulfuric acid in the acid discharge groove 206 falls into the ground plug 202 under the action of gravity, thereby reacting with the zinc metal to generate a large amount of gas. The gas will drive the piston rod 209 to move upward and push the connecting top plate 207 to move, at which time the connecting top plate 207 will lift the surface of the support frame 100 at this position, thereby correcting the inclination caused by settlement. Since the acid discharge groove 206 is configured as a plane and is symmetrically arranged, slight vibration or temporary inclination is not enough to cause acid flow. Only the inclination caused by continuous and significant settlement will trigger the reaction, avoiding frequent false actions. The acid storage shell 203 on the floating side will not release acid liquid because it is at a high position, so the ground plug 202 on this side will not generate gas and will not participate in the lifting action, ensuring that the adjustment only acts on the settlement side to achieve one-way precise compensation.

[0042] In summary, the support frame 100 serves as the main load-bearing frame, and the pouring load plate 102 is arranged inside for prefabricating the cast concrete member on site or in the factory, ensuring consistent molding quality, smooth surface, and controllable slope. A plurality of lifting holes 101 are evenly arranged on one side of the support frame 100, facilitating overall lifting and transportation using hoisting equipment, significantly improving the efficiency of assembly-type construction. The metal zinc material is pre-installed inside the ground plug 202, which is chemically active and can rapidly react with the flowing acid liquid to generate a large amount of gas. The gas is guided into the plurality of air cylinders 208 arranged at the top of the ground plug 202, and the air cylinder 208 is internally provided with a slidable piston rod 209, the top of which is fixedly connected with the connecting top plate 207. As the gas pressure gradually increases, the piston rod 209 moves upward under the action of gas pressure, driving the connecting top plate 207 to lift, and in turn lifting the support frame 100 on this side. The reaction of sulfuric acid and zinc is an exothermic process, which can prevent the ground plug 202 from freezing, and at the same time, the system does not require external energy input, which is suitable for low-temperature environments, and can also conduct heat to the support frame tube 200 to heat the cast concrete.

[0043] Embodiment two: please refer to Figure 1 Figure 10 The present application also provides a technical solution, which is different from the technical solution of embodiment one: a prefabricated cast support frame also includes an air pipe 300 arranged inside the inner tube 201, and the air pipe 300 is internally provided with an analysis component for detecting cracks in the prefabricated cast, which provides power support for the piston rod 209.

[0044] It also includes a foot pressing connecting plate 400 for connecting with the outer wall foot pressing, and one side of the support frame 100 is provided with a mounting groove for sliding connection of the foot pressing connecting plate 400, and a damping component is arranged in the mounting groove for absorbing the resonance force generated by the support frame 100, and the damping component is used to provide power for the analysis component. By arranging the foot pressing connecting plate 400, the wall foot pressing can be connected to assist in supporting the support frame 100, and the soft connection between the foot pressing connecting plate 400 and the support frame 100 can absorb the resonance force when the support frame 100 is vibrated to reduce the breaking.

[0045] ​Further, the analysis assembly comprises a first double-headed piston rod 301 slidably connected to the bottom of the air pipe 300, the top of the air pipe 300 is slidably connected with a second double-headed piston rod 302, the outer surface of the second double-headed piston rod 302 is sleeved with a positioning sleeve spring 303 for self-resetting, a shunt air pipe 304 is arranged in the support frame 100 and communicates with a plurality of air pipes 300, the air pipe 300 is arranged in the inner pipe 201 to form an independent gas transmission channel, which can be used for conveying detection gas to the inside of the support frame pipe 200 and also can be used as an auxiliary gas pressure source for the action of the piston rod 209, so that one gas is used in multiple ways, the top of each inner pipe 201 is provided with a gas vent groove 204 for discharging gas, and a plurality of measuring seam grooves 205 for discharging gas are arranged in the inside of the support frame pipe 200, the gas vent groove 204 and the measuring seam groove 205 are arranged to discharge gas and contact with the water when gas is supplied to the inside of the inner pipe 201, so as to judge whether there is a gap, and the foot pressing connecting plate 400 can detect the horizontal settlement of the support frame 100, when the support frame 100 appears to be settled, the gas in the air pipe 300 can be increased to push the second double-headed piston rod 302 to move, so that the second double-headed piston rod 302 presses the gas in the inner pipe 201 to push the gas to discharge through the gas vent groove 204 to detect the gap of the water, if the gas can pass through the water and discharge, it means that the water has a crack, and the second double-headed piston rod 302 will be reset under the action of the positioning sleeve spring 303, at this time, it is judged that the water has a crack, and when the second double-headed piston rod 302 remains stationary, it means that the water does not have a crack and cannot discharge gas, the second double-headed piston rod 302 can have a positioning function to feed back to the outside whether it moves or not, or the positioning sleeve spring 303 is provided with a positioning function to judge whether it drives the second double-headed piston rod 302 to move.

[0046] The damping assembly comprises a connecting handle 401 rotatably connected to the mounting groove, the connecting handle 401 is sleeved with a torsional spring at the connecting position with the mounting groove, one end of the connecting handle 401 is rotatably connected with a hinged seat 402, the bottom of the foot pressing connecting plate 400 is fixedly connected with a positioning sliding strip 403, the hinged seat 402 is slidably connected to the surface of the positioning sliding strip 403, and the positioning sliding strip 403 is used for detecting the position of the hinged seat 402, through the cooperation of the connecting handle 401 and the hinged seat 402, the hinged seat 402 can slide on the surface of the positioning sliding strip 403 when the support frame 100 is vibrated, so as to absorb the energy generated by the dislocation, and the torsional spring and the friction force can be used to absorb and release the resonance force, and the positioning sliding strip 403 can be used to detect the position of the hinged seat 402, so as to realize real-time understanding of the settlement and vibration of the support frame 100.

[0047] Further, the installation groove is fixedly connected with the air transmission cylinder 305, the top of the air transmission cylinder 305 is communicated with the shunt air pipe 304 through the air conveying pipe 306, one end of the connecting handle 401 is fixedly connected with the crank 404, one end of the crank 404 is rotatably connected with the pull handle 405, one end of the pull handle 405 is fixedly connected with the air pressing rod 406 which is slidably connected with the air transmission cylinder 305, with the occurrence of subsidence, the air pressing rod 406 will continuously extrude the gas in the air transmission cylinder 305, so that the gas enters the shunt air pipe 304 through the air conveying pipe 306, thereby increasing the gas in the air pipe 300 and moving the second double-headed piston rod 302 and the first double-headed piston rod 301 respectively.

[0048] Wherein, the air conveying pipe 306 is provided with a one-way valve for the gas in the air transmission cylinder 305 to flow into the shunt air pipe 304 in one direction, the top of the air transmission cylinder 305 is provided with a valve for the gas to enter the inside of the air transmission cylinder 305, the one-way valve is provided for the gas in the air transmission cylinder 305 to pass through the shunt air pipe 304, so that the gas does not flow back, the valve at the top of the air transmission cylinder 305 is convenient for the external gas to enter the air transmission cylinder 305 for the air pressing rod 406 to reset, the first double-headed piston rod 301 is linked with the ground plug 202, when the gas pressure in the air pipe 300 rises, one end of the first double-headed piston rod 301 pushes the piston rod 209 in the ground plug 202 to extend outward, realizing the composite power output of chemical compensation and gas driving; the other end of the first double-headed piston rod 301 extrudes the gas at the bottom of the inner pipe 201, forming a local high-pressure area, enhancing the gas injection intensity of the air vent groove 204, and improving the crack detection sensitivity; the second double-headed piston rod 302 and the positioning sleeve spring 303 constitute a mechanical feedback unit: when there is a crack in the water distribution, the gas escapes through the crack, causing the pressure in the air pipe 300 to drop, the positioning sleeve spring 303 pushes the second double-headed piston rod 302 to reset, the displacement amount of the second double-headed piston rod 302 is converted into an electric signal through the built-in magnetic scale sensor, and the crack width is fed back in real time; if the water distribution is dense, the gas pressure continues to rise, the second double-headed piston rod 302 is locked at the limit position, triggering the "no crack" signal.

[0049] Specifically, when the two ends of the support frame 100 simultaneously settle, the height between the foot pressing connecting plate 400 and the support frame 100 changes, and in this process, the hinge seat 402 is pulled by the foot pressing connecting plate 400 to slide on the surface of the positioning slide 403, thereby driving the connecting handle 401 to rotate, so that the crank 404 rotates to drive the pull handle 405 to be raised, thereby driving the air pressing rod 406 to press the gas in the air cylinder 305, so that the gas is transported to the shunt air pipe 304 through the air pipe 306, and then is shunted to the inner pipes 201, and then enters the inside of the air pipe 300 to synchronously drive the first double-headed piston rod 301 and the second double-headed piston rod 302 to move, so that one end of the first double-headed piston rod 301 presses the gas in the inner pipe 202, and simultaneously drives the plurality of piston rods 209 to move, and at the same time, the increase of the gas in the air pipe 300 also pushes one end of the second double-headed piston rod 302 to move in the inner pipe 201, so as to press the gas to be discharged through the plurality of air vent grooves 204, and then to be discharged through the joint detection groove 205 to contact the water apron, so as to detect whether the water apron has cracks due to settlement, and the second double-headed piston rod 302 can detect the moving position of itself, so as to judge whether the water apron has cracks to cause gas leakage.

[0050] In summary, when the system detects the settlement trend, the gas is introduced into the air pipe 300 to push the second double-headed piston rod 302 to move, compress the gas in the inner pipe 201, and make the gas enter the support frame pipe 200 through the air vent groove 204, and then be discharged through the joint detection groove 205 to contact the surface of the prefabricated water apron. If the water apron has micro-cracks, the gas will escape through the cracks to cause the pressure in the system to decrease, and the second double-headed piston rod 302 will complete the full stroke movement due to the decrease of the resistance, and will feed back the “displacement occurrence” signal under the action of the positioning sleeve spring 303 or the built-in positioning structure, so as to determine that there are cracks. If the water apron is intact, the gas cannot be discharged due to the resistance, and the pressure continuously acts on the second double-headed piston rod 302, so that it is difficult to move or only slightly moves, and the system determines that the structure is intact accordingly, so as to realize the non-destructive detection of the hidden micro-cracks, avoid the accumulation of damage that is difficult to be detected by the naked eye, and realize the state visualization and early warning function by remotely reading the displacement state of the second double-headed piston rod 302. The foot pressing connecting plate 400 is slidably connected with the support frame 100 through the mounting groove, and cooperates with the damping assembly composed of the connecting handle 401, the torsional spring and the positioning slide 403 to effectively absorb vibration energy and inhibit resonance propagation.

[0051] Embodiment three: please refer to Figure 1 - Figure 10 The present application also provides a technical solution, which is different from the technical solution of embodiment one: a construction method of a support frame for a prefabricated water apron, comprising the following steps:

[0052] S1. When in use, concrete is first poured into the support frame 100 and placed on top of the pouring plate 102, and then submerged multiple support frame pipes 200 to form a drainage system.

[0053] S2. Embed the support frame 100 in the soil layer, and fix the plinth connecting plate 400 to the plinth of the outer wall with bolts 407 to ensure that the support frame 100 and the plinth are stably connected and flat.

[0054] S3. The acid drain tank 206 contains sulfuric acid, while the ground socket 202 contains zinc metal. When the support frame 100 settles and the two ends are not on the same horizontal line, the acid storage shell 203 will tilt, so that the acid storage shell 203 at the lower position tilts and the sulfuric acid in the acid drain tank 206 falls into the ground socket 202 by gravity, thereby reacting with the zinc metal to produce a large amount of gas. This gas will drive the piston rod 209 to move upward, thereby pushing the connecting top plate 207 to move. At this time, the connecting top plate 207 will raise the surface of the support frame 100 located at this position, thereby correcting its tilt caused by the settlement.

[0055] S4. When both ends of the support frame 100 settle synchronously, the height between the foot plate 400 and the support frame 100 will change. During this process, the hinge seat 402 will slide on the surface of the positioning slide bar 403 under the traction of the foot plate 400, thereby driving the connecting handle 401 to rotate, causing the crank 404 to rotate and causing the pull handle 405 to tilt up, thereby driving the air compressor rod 406 to compress the gas in the air cylinder 305, so that the gas is delivered through the air pipe 306 to the diversion pipe 304, and then diverted to multiple inner pipes 201, and then enters the interior of the air pipe 300 to drive synchronously. The first double-ended piston rod 301 and the second double-ended piston rod 302 move, causing one end of the first double-ended piston rod 301 to compress the gas in the ground insert 202, synchronously driving multiple piston rods 209 to move. At the same time, the increase in gas in the gas pipe 300 will also push one end of the second double-ended piston rod 302 to move in the inner pipe 201, thereby compressing the gas and discharging it through multiple venting grooves 204. After being discharged through the crack measuring groove 205, it comes into contact with the water spray to detect whether the water spray has cracks due to settlement. The second double-ended piston rod 302 can detect its own movement position, thereby determining whether there are cracks in the water spray to allow gas to leak out.

[0056] In summary, by pouring concrete within the support frame 100 and covering it with the cast-in-place slab 102, standardized production or precise on-site molding of the drainage components can be achieved, avoiding problems such as traditional on-site formwork, long curing periods, and uneven slopes. The concrete submerges multiple support frame pipes 200, forming a reinforced mesh composite structure, significantly improving the overall strength and crack resistance of the drainage slab. By pre-embedding the support frame 100 in the soil layer and fixing it to the external wall plinth with bolts 407 using the plinth connecting plate 400, a dual anchoring system of "foundation insertion + wall tie" is formed. When the support frame 100... When uneven settlement occurs, the lower side acid storage shell 203 tilts, and sulfuric acid in the acid discharge tank 206 flows into the ground insert 202, reacts with zinc metal to produce gas, pushes the piston rod 209 to move upward, and drives the connecting top plate 207 to lift the structure on this side. The compressed gas enters the gas pipe 300 through the gas supply pipe 306 and the diversion gas pipe 304, pushes the second double-headed piston rod 302 to move, and makes the gas discharged through the venting groove 204 and the side groove 205, and comes into contact with the water. When the two ends of the support frame 100 settle simultaneously, the change in height between the foot connecting plate 400 and the support frame 100 will trigger a series of linkage reactions. The hinge seat 402 slides on the surface of the positioning slide bar 403, driving the connecting handle 401 to rotate. This causes the crank 404 to rotate, which in turn causes the pull handle 405 to lift. This causes the air compressor 406 to compress the gas in the air transmission cylinder 305, which is then transported to the air pipe 300 through the air supply pipe 306, the diversion pipe 304, and the inner pipe 201. This simultaneously drives the first double-ended piston rod 301 and the second double-ended piston rod 302 to move. This process not only assists in adjustment by driving multiple piston rods 209 to move through the compressed gas in the ground insert 202, but also increases the gas volume in the air pipe 300, pushing one end of the second double-ended piston rod 302 to move within the inner pipe 201. The compressed gas is discharged through multiple venting grooves 204 and then through the crack detection groove 205, where it comes into contact with the water spray to detect whether the water spray has cracked due to settlement. Meanwhile, the second double-headed piston rod 302 can detect its own movement position and determine whether there are cracks in the apron causing gas leakage based on its position changes. It can promptly detect cracks in the apron caused by settlement, making it easier to take timely repair measures and ensure the integrity and safety of the building structure.
