Description

Technical Field

[0001] This invention relates to the field of wastewater recycling, and more particularly to a device for recycling and filtering maintenance water and rainwater for continuous beams used in construction. Background Technology

[0002] In the construction of large bridges, especially cantilevered formwork for variable cross-section continuous beams, the curing of the box girder concrete is a crucial step in ensuring project quality, typically requiring several days of continuous spraying for moisture retention. This process, along with dust suppression at the construction site, consumes a significant amount of water. Furthermore, construction interfaces (such as the formwork platform) collect substantial amounts of rainwater during rainy weather. Traditional practices often involve directly discharging this curing wastewater, which is mixed with cement slurry, admixture residues, and environmental dust. This not only results in a severe waste of water resources but also risks polluting surrounding soil and waterways due to its alkalinity and the presence of solid impurities, severely contradicting the current advocacy for green and low-carbon construction. Therefore, effectively recycling, filtering, and treating the curing water and rainwater generated during continuous beam construction to a level suitable for reuse is an urgent and practical necessity for reducing project water costs, minimizing negative environmental impacts, and enhancing construction sustainability.

[0003] However, existing technologies for treating curing water and rainwater from continuous beams have shortcomings, making it difficult to achieve efficient and economical closed-loop management under complex construction site conditions. Common practices often rely on simple sedimentation tanks or mobile container water tanks under the bridge, but their treatment effectiveness is limited. First, simple sedimentation cannot remove suspended fine colloidal particles and microorganisms from the water, leading to water quality deterioration and foul odors. Reusing this water for curing may clog spraying equipment or affect the surface quality of the concrete. Second, if flocculants, disinfectants, or other purifying agents need to be added, it usually relies on manual estimation and addition, making precise control of the dosage difficult and prone to waste or substandard treatment results. Furthermore, the critical filtration stage often uses fixed filter screens or cartridges, which are prone to rapid clogging in water rich in viscous cement slurry impurities, resulting in a sharp drop in filtration efficiency, cumbersome cleaning and replacement, low automation, and an inability to guarantee continuous and stable treatment capacity. Finally, existing devices are often single-function and lack intelligent design that integrates with clean energy. Overall, they suffer from problems such as low processing efficiency, high operation and maintenance costs, and difficulty in long-term stable automatic operation, which restricts the large-scale and effective promotion of water resource recycling technology in bridge construction. Summary of the Invention

[0004] To address the problems existing in the background technology, a continuous beam construction water and rainwater recycling and filtration treatment device is proposed. It can not only recycle most of the curing water, but also effectively intercept solid waste such as concrete residue, and prevent construction wastewater from polluting the site and surrounding river environment. It raises the environmental management of concrete curing operations to a reliable and controllable new standard, and has important demonstration and promotion value.

[0005] This invention proposes a continuous beam construction water and rainwater recovery and filtration device, including a treatment tank, a filter screen, a mixing component, a cleaning component, and a solar cover. Water enters through the top inlet of the treatment tank, which is divided into an upper water storage chamber and a lower cleaning chamber. The upper water storage chamber is further divided into a one-way connected recovery chamber and a liquid storage chamber by an internal piston lifting plate. The recovery chamber is used for recovering maintenance water and rainwater and is equipped with a drain outlet. The liquid storage chamber is used for storing a purifying agent. As the amount of maintenance water and rainwater increases, the piston lifting plate presses down under the weight, forcing the purifying agent into the recovery chamber. An upper opening connecting to the recovery chamber is opened on the upper side wall of the treatment tank, and a lower opening connecting to the lower cleaning chamber is opened on the lower side wall. A slag collection box connecting to the lower cleaning chamber is provided at the bottom. The filter screen is annular, with the upper end being a filter... The filter end is a movable filter located above the piston lifting plate. It passes through the recovery chamber and covers the top opening of the treatment box, then extends out from the upper opening. The lower end is the end to be cleaned, which passes through the lower cleaning chamber and extends out from the lower opening. The mixing component is located between the piston lifting plate and the filter end of the filter screen to promote the mixing of the purifying agent and the wastewater. The cleaning component is located at the cleaning end of the filter screen to clean the deposits on the filter screen. The solar cover is rotatably set on both sides of the top opening of the treatment box and slides along both sides of the treatment box. Rotatable display plates are provided on both sides of the solar cover.

[0006] Preferably, positioning guide rollers are provided on the outside of both the upper and lower openings; multiple sets of positioning guide rollers are wound around the filter screen to form a rotating U-shaped structure; a pre-treatment component for the filter screen is provided on the upper opening; and a post-treatment component for the filter screen is provided on the lower opening.

[0007] Preferably, the pretreatment component includes a mounting base located at the top of the upper opening; the interceptor plate is raised and lowered below the mounting base via a telescopic rod, and a scraping and pressing strip is provided at the bottom of the interceptor plate.

[0008] Preferably, the post-processing component includes a mounting bracket located at the bottom of the lower opening; a flip plate is rotatably mounted on the mounting bracket, and a pusher plate that moves back and forth is provided on the side of the flip plate facing the lower opening.

[0009] Preferably, the upper and lower openings are located in the width direction of the processing box; a sliding rod is provided in the length direction of the processing box; a sliding sleeve that can slide back and forth is fitted on the sliding rod; telescopic sleeves are provided on both sides of the sliding sleeve; the solar cover is rotatably mounted on the sliding sleeve, and a solar panel is provided on its upward-facing side; the display plate is rotatably mounted on the left and right sides of the sliding sleeve, and a reflector is provided on its unfolded surface.

[0010] Preferably, the edges of the display panel are provided with flexible connecting edges.

[0011] Preferably, a nozzle is provided above the piston lifting plate and a return spring is provided below it; the liquid storage chamber is connected to the nozzle through one-way valve one and to the liquid storage tank through one-way valve two.

[0012] Preferably, the mixing component and the cleaning component work synchronously through a drive component; the drive component includes a rotating pulley one and a pulley two connected above the pulley one by a belt; the mixing component works synchronously through the rotation of the pulley two; a main eccentric wheel is coaxially connected to one side of the pulley one; an auxiliary eccentric wheel is located on one side of the main eccentric wheel, and is pushed to rotate with the rotation of the main eccentric wheel, and is pulled back to its original position by a torsion spring; the cleaning component works synchronously through the rotation and reset of the auxiliary eccentric wheel.

[0013] Preferably, the mixing component includes a mixing shaft coaxially connected to the second pulley; the mixing shaft passes through the recovery chamber, and mixing blades are sleeved on the shaft.

[0014] Preferably, the cleaning components are arranged in pairs and are located on the upper and lower sides of the filter screen to be cleaned respectively; each set of cleaning components includes a rotating shaft, with a gear passing through the middle of the rotating shaft and an auxiliary eccentric wheel extending into the end; a rack is provided on the side of the cleaning seat away from the filter screen; the rack meshes with the gear; a lifting platform is provided on the side of the cleaning seat close to the filter screen; a rubbing strip is provided on the lifting platform.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: In this invention, the solar panel cover and the display panel constitute an intelligent energy and water collection system. They can be flexibly deployed as needed, serving as diversion channels to efficiently collect maintenance water and rainwater from the bridge deck and the air, expanding the water collection area; the solar panels covering their surfaces also provide green electricity for the internal drive motors, water pumps, etc., enabling the system to achieve energy self-sufficiency in field construction scenarios. This design reduces dependence on grid electricity, lowering indirect energy consumption in traditional water recycling processes at the source, aligning with the concept of green construction. Through the coordinated operation of the annular filter, piston lifting plate for chemical dosing, and mixing components, a highly efficient physicochemical combined treatment process is formed. The continuous rotation of the annular filter, along with the automatic rubbing and cleaning of the cleaning and pretreatment components, overcomes the problems of easy clogging and frequent replacement of traditional fixed filters, ensuring long-term stable filtration efficiency. In particular, the design of the piston lifting plate can automatically and proportionally pressurize the purifying agent into the storage chamber according to the influent water volume. This agent is then released through the nozzle and fully reacts with the wastewater under the action of the mixing blades, achieving precise matching of the dosage to the water treatment requirements. This not only ensures that the effluent water quality meets the requirements for concrete curing but also enables the entire recycling, purification, and reuse process to operate continuously without manual intervention, resulting in extremely high water resource recycling efficiency. The device integrates filtration, cleaning, chemical dosing, and slag collection modules, achieving full automation throughout the process. It controls the process from the source (hanging basket, A-frame slope, slag trap) to the end-stage use of purified water for curing and dust suppression, forming a complete closed loop. This design changes the traditional extensive model of indiscriminate discharge and difficult collection and treatment of curing water during construction. It not only recovers most of the curing water but also effectively intercepts solid waste such as concrete residue, preventing construction wastewater from polluting the site and surrounding waterways. This elevates the environmental management of concrete curing operations to a reliable and controllable new standard, possessing significant demonstration and promotion value.

Detailed Implementation

[0017] Example 1, as Figures 2-6 As shown, this invention proposes a continuous beam construction water and rainwater recovery and filtration treatment device, including a treatment tank 1, a filter screen 4, a mixing component 6, a cleaning component 5, and a solar cover plate 9. Water enters through the top inlet 19 of the treatment tank 1, which is divided into an upper water storage chamber and a lower cleaning chamber 103. The upper water storage chamber is further divided by a piston lifting plate 2 inside into a one-way connected recovery chamber 101 and a liquid storage chamber 102. The recovery chamber 101 is used for recovering water and rainwater and is equipped with a drain outlet 18, with a water outlet pipe on the side wall. The liquid storage chamber 102 is used for storing a purifying agent. As the amount of water and rainwater increases, the piston lifting plate 2 presses down under the weight, forcing the purifying agent into the recovery chamber 101. The upper side wall of the treatment tank 1 has an upper opening 104 connecting to the recovery chamber 101, and the lower side wall has a lower opening 105 connecting to the lower cleaning chamber 103. A slag collection box is provided at the bottom, connecting to the lower cleaning chamber 103. 7; The filter screen 4 is ring-shaped, with the upper end being the filter end, which moves above the piston lifting plate 2 for filtration, passing through the recovery chamber 101 and covering the top opening of the treatment box 1, and then extending out from the upper opening 104. The lower end is the end to be cleaned, which passes through the lower cleaning chamber 103 and extends out from the lower opening 105; The mixing component 6 is located between the piston lifting plate 2 and the filter end of the filter screen 4, and is used to promote the mixing of the purifying agent and the wastewater; The cleaning component 5 is located at the cleaning end of the filter screen 4, and is used to clean the deposits on the filter screen 4; The solar cover 9 is rotatably set on both sides of the top opening of the treatment box 1, and slides along both sides of the treatment box 1. Rotatable display plates 3 are provided on both sides of the solar cover 9.

[0018] It should be further explained that positioning guide rollers are provided on the outside of both the upper opening 104 and the lower opening 105; multiple sets of positioning guide rollers are wound around the filter screen 4 to form a rotating U-shaped structure; a pre-treatment component 13 is provided on the upper opening 104 to act on the filter screen 4; a post-treatment component 8 is provided on the lower opening 105 to act on the filter screen 4; after the continuous beam maintenance water and rainwater enter the treatment tank 1, the impurities and dirt in them are intercepted by the clean end of the upper filter screen 4, achieving preliminary filtration treatment. After a period of time, the filter screen 4 rotates, driving the clean end with attached impurities and dirt to move out of the upper opening 104 and into the lower opening 105, and finally into the lower cleaning chamber 103 for cleaning. The entire U-shaped filter screen 4 is recycled and automatically cleaned to ensure its recycling filtration effect.

[0019] like Figure 7 As shown, the pretreatment component 13 includes a mounting base 1301 located at the top of the upper opening 104; an intercepting plate 1302 is raised and lowered below the mounting base 1301 via a telescopic rod, and a scraping and crushing strip 1303 is provided at the bottom of the intercepting plate 1302; when performing maintenance water and rainwater recycling, the intercepting plate 1302 descends to block the upper opening 104, on the one hand preventing sewage from flowing out, and on the other hand pressing down on the filter screen 4 to fix it. When cleaning the filter screen 4, the filter screen 4 moves, and the intercepting plate 1302 drives the scraping and crushing strip 1303 to move up and down, on the one hand crushing the clumps of debris to facilitate removal from the upper opening 104, and on the other hand cleaning the mesh surface of the filter screen 4.

[0020] like Figure 8 As shown, the post-processing component 8 includes a mounting bracket 801 located at the bottom of the lower opening 105; a flipping plate 802 is rotatably mounted on the mounting bracket 801 by a motor drive, and a pusher plate 804, driven to move back and forth by a cylinder 803, is provided on the side of the flipping plate 802 facing the lower opening 105; when cleaning the filter screen 4, the flipping plate 802 flips outward to guide the debris on the filter screen 4 into the lower opening 105. The flipping plate 802 then flips back towards the lower opening 105, and the pusher plate 804 moves within the lower cleaning chamber 103 to further gather the collected debris, compress it into shape, and send it into the slag collection box 7.

[0021] like Figure 9As shown, the upper opening 104 and the lower opening 105 are located in the width direction of the processing box 1; a sliding rod is provided in the length direction of the processing box 1; a sliding sleeve 14 that can slide back and forth is fitted on the sliding rod; telescopic sleeves 15 are provided on both sides of the sliding sleeve 14; the solar cover plate 9 is rotated and mounted on the sliding sleeve 14 by a motor, and a solar panel is mounted on its upward-facing side; the display plate 3 is rotated and mounted on the left and right sides of the sliding sleeve 14 by a motor, and a reflector is mounted on its unfolded surface; when operating outdoors, the solar cover plate 9 and the two side display plates 3 rotate to unfold, which can efficiently collect solar energy to power the device, and also push against the bottom of the continuous beam or unfold upward to recover maintenance water and rainwater. In other words, the solar cover plate 9 and the two side display plates 3 have a dual function of energy collection and water guiding, which can collect energy on one side and guide water on the other side, or they can work simultaneously, enhancing the functionality and flexibility of the device. In addition, when the equipment is not in use for a long period of time, the solar cover plate 9 and the two side panels 3 can be brought together. Then, by sliding the two side sliding sleeves 14, the two sets of solar cover plates 9 can be adjusted to be one in front of the other, with their positions staggered. This allows the two sets of solar cover plates 9 to be flipped over, covering the water inlet 20 and reducing the entry of debris (see...). Figure 2 ).

[0022] It should be further explained that the edge of the display panel 3 is provided with a flexible connecting edge 16, which can connect the solar cover plate 9 and the telescopic sleeve 15 when unfolded, reducing water leakage.

[0023] like Figure 10 As shown, a nozzle 17 is provided above the piston lifting plate 2, and a return spring 10 is provided below it; the liquid storage chamber 102 is connected to the nozzle 17 through one-way valve one, and connected to the liquid storage tank 11 through one-way valve two.

[0024] The storage tank 11 contains a mixed solution of flocculant and disinfectant. The flocculant (such as polyaluminum chloride) causes fine particles and colloids in the water to aggregate and settle. The disinfectant (such as sodium hypochlorite or chlorine dioxide) can kill microorganisms.

[0025] As the amount of maintenance water and rainwater recovered increases, the pressure on the piston lifting plate 2 increases and it moves downward, squeezing the purifying agent (a mixed solution of flocculant and disinfectant) in the storage chamber 102. The purifying agent enters the recovery chamber 101 and mixes with the sewage, and the amount added is related to the amount of sewage. After the sewage in the upper storage chamber is treated, it is discharged, and the piston lifting plate 2 moves upward as the pressure decreases, allowing the purifying agent in the storage tank 11 to be introduced into the storage chamber 102.

[0026] like Figure 11As shown, the mixing component 6 and the cleaning component 5 work synchronously through the driving component 12; the driving component 12 includes a pulley 1204 driven to rotate by a drive motor 1203 and a pulley 1201 connected above the pulley 1204 by a belt 1202; the mixing component 6 is synchronized by the rotation of the pulley 1201; a main eccentric wheel 1205 is coaxially connected to one side of the pulley 1204; an auxiliary eccentric wheel 1206 is located on one side of the main eccentric wheel 1205, and is pushed to rotate with the rotation of the main eccentric wheel 1205, and is pulled back to its original position by a torsion spring; the cleaning component 5 is synchronized by the rotation and reset of the auxiliary eccentric wheel 1206.

[0027] like Figure 11 As shown, the mixing component 6 includes a mixing shaft coaxially connected to the second pulley 1201; the mixing shaft passes through the recovery chamber 101, and a mixing blade is sleeved on the shaft; when the second pulley 1201 rotates, the mixing shaft and the mixing blade rotate synchronously, accelerating the mixing of the purifying agent and the wastewater, and promoting purification.

[0028] like Figure 12 As shown, the cleaning components 5 are arranged in pairs and are located on the upper and lower sides of the end of the filter screen 4 to be cleaned, respectively. Each set of cleaning components 5 includes a rotating shaft 501, with a gear 502 passing through the middle of the rotating shaft 501 and an auxiliary eccentric wheel 1206 extending into the end. A rack 503 is provided on the side of the cleaning seat 504 away from the filter screen 4. The rack 503 meshes with the gear 502. A lifting platform 505 is provided on the side of the cleaning seat 504 close to the filter screen 4. A rubbing strip 506 is provided on the lifting platform 505.

[0029] It should be further explained that the main eccentric wheel 1205 is designed with a double-headed protrusion, while the auxiliary eccentric wheel 1206 has a single-headed protrusion. When the main eccentric wheel 1205 rotates, the double-headed protrusion first contacts the auxiliary eccentric wheel 1206, causing the upper and lower auxiliary eccentric wheels 1206 to rotate in the opposite direction. When the double-headed protrusion rotates away from the auxiliary eccentric wheel 1206, the torsion spring causes the upper and lower auxiliary eccentric wheels 1206 to return to their original position. This forms a reciprocating horizontal movement trajectory, thereby achieving the purpose of cleaning the filter screen 4. The lifting platform 505, controlled by the electrically controlled telescopic structure, can drive the rubbing strip 506 to move up and down, adjusting its distance from the filter screen 4 to ensure the cleaning effect. The cleaned dirt finally enters the sludge collection box 7.

[0030] Example 2: Based on the construction continuous beam curing water and rainwater recycling and filtration treatment device in the above examples, this example proposes a method for continuous beam curing water and rainwater recycling and filtration treatment, the steps of which are as follows: A 2% herringbone slope is set at the bottom of the hanging basket to allow residual curing water and rainwater on the construction surface to flow naturally into the pre-designed water collection channel. A slag trap 20 is installed at the drainage outlet of the box girder bottom formwork, with a mesh cover on top. This structure can intercept concrete fragments, larger particles, and other impurities, preventing blockage of subsequent pipelines and the water collection tank. The pre-filtered water flows into the recovery chamber 101 of the treatment tank 1. The water first enters through the filter end of the filter screen 4 (located above the piston lifting plate 2). The filter screen 4 is annular, and its cleaning part continuously intercepts suspended particles in the water, achieving preliminary physical filtration. The storage chamber 102 pre-stores a mixed purification agent solution prepared from flocculants (such as polyaluminum chloride) and disinfectants (such as sodium hypochlorite). As the water flow into the recovery chamber 101 increases, the water level rises, increasing the pressure on the piston lifting plate 2, causing it to move downwards against the resistance of the return spring 10. The downward movement of the piston lifting plate 2 compresses the liquid storage chamber 102, causing the purifying agent to be quantitatively injected into the wastewater in the recovery chamber 101 through the one-way valve and the nozzle 17. The more water enters, the greater the downward displacement, and the corresponding increase in dosage, realizing the linkage control between the agent dosage and the water inflow. Driven by the drive component 12, the mixing component 6 (i.e., the mixing shaft and the blades) begins to rotate, stirring the water and purifying agent in the recovery chamber 101, accelerating the flocculant's trapping and bridging effect on colloidal particles, and the disinfectant's killing process on microorganisms, thereby significantly improving the purification efficiency. After a period of operation, the drive system starts, causing the annular filter screen 4 to move cyclically along the "U"-shaped path formed by the positioning guide rollers. The screen surface with attached impurities (the original filter end) moves out from the upper opening 104 and passes through the pretreatment component 13. At this time, the scraping and crushing strips 1303 at the bottom of the interceptor plate 1302 move up and down, crushing the clumps of debris and peeling them off the screen surface, completing the first cleaning. This section of the screen surface continues to move to the lower opening 105 and enters the lower cleaning chamber 103. The cleaning component 5 located here begins to work: driven by the auxiliary eccentric wheel 1206 and the rack 503, the cleaning seat 504 drives the rubbing strips 506 to rub the screen surface up and down and back and forth, thoroughly removing the embedded fine dirt. The cleaned screen surface moves again above the piston lifting plate 2, becoming a new filter end, realizing the online automatic renewal and recycling of the filter screen 4, ensuring continuous and stable filtration efficiency; During the cleaning process, the detached dirt falls into the bottom of the lower cleaning chamber 103. The post-processing unit 8 is activated, the flipping plate 802 flips outward to guide the dirt, and then the pushing plate 804, driven by the cylinder 803, pushes and compacts the dirt, and finally sends it into the slag collection box 7 for centralized processing to keep the chamber clean; After the flocculation and disinfection reactions are completed in the recovery chamber 101, the water can be pumped into the storage tank through pipes on the side wall for static sedimentation, allowing the flocs to settle fully and the upper layer to obtain clear purified water. The settled water is discharged from the drain outlet 18 by a water pump and can be directly used for continuous spray curing of box girder concrete, dust suppression at construction sites, etc., realizing closed-loop recycling of water resources. After the treated water is discharged, the water level in the recovery chamber 101 drops, and the piston lifting plate 2 moves upward under the action of the return spring 10, creating negative pressure in the storage chamber 102. At this time, the purifying agent in the external storage tank 11 is automatically drawn into the storage chamber 102 through the one-way valve 2, completing the automatic replenishment of the agent reserve and preparing for the next treatment. The solar cover 9 on top of the device and the two side panels 3 (covered with solar panels and reflectors) can be unfolded as needed. On the one hand, they collect solar energy to provide green electricity for the motors and water pumps inside the device; on the other hand, their unfolded form can serve as a water channel to enhance the efficiency of collecting rainwater from the bridge deck and the air.

[0031] The installation process of the above-mentioned device is as follows: Figure 1 As shown: The top of the slag-retaining cylinder 20 is equipped with a mesh cover. A flange is welded or installed on the upper outer side of the cylinder. A hole is precisely drilled according to the flange size at the pre-set drain outlet position on the bottom formwork of the box girder. A reinforcing back plate is installed on the inner side (top) of the formwork to distribute the stress and prevent local deformation of the formwork. The slag-retaining cylinder 20 is inserted into the drain outlet from below the formwork, so that the flange fits against the bottom surface of the formwork, with a rubber sealing gasket sandwiched in between. The reinforcing back plate is passed through from above the formwork and tightened with bolts to achieve a seal and secure connection.

[0032] The hose uses a corrosion-resistant metal corrugated hose or a high-strength plastic corrugated hose, with standard connectors at the ends. The upper end of the hose is tightly connected to the bottom outlet of the slag trap 20 via a hose clamp (stainless steel clamp). The lower end of the hose is connected to the top of the recovery chamber 101 of the treatment tank 1. The length and flexibility of the hose effectively absorb minor displacements and vibrations during construction.

[0033] At the planned installation location of the treatment box 1 (such as the bottom of the hanging basket or the bottom surface of the existing beam), fix two load-bearing crossbeams (channel steel or I-beams can be used) in parallel. Use height-adjustable suspension clamps (such as screw type or chain type). The upper end of the clamp is hung on the load-bearing crossbeam, and the lower end is connected to the fixing lugs welded to the treatment box 1 by bolts. Adjust the clamps to ensure that the treatment box 1 is in a horizontal position to ensure the normal operation of internal moving parts such as the piston lifting plate. Finally, tighten all connecting parts.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
