Description

Technical Field

[0001] The present invention relates to the field of drainage in construction engineering, and more specifically, to a rapid construction method for a fiberglass drainage ditch at an airport without suspending flights. Background Art

[0002] Airport drainage ditches mainly undertake the task of discharging precipitation between the taxiway and apron in the flight area and treated sewage in the terminal building. A good drainage system can effectively avoid potential threats to airport facilities and flight safety caused by waterlogging, ensuring the smoothness of airport ground traffic and the normal use of various facilities. At present, most of the existing airport drainage ditches in China adopt a structural form of a reinforced concrete ditch body with a grating cover plate. However, with the continuous development of airport construction in China and the gradual improvement of requirements for airport operation efficiency and safety, this traditional airport drainage ditch structure has been difficult to meet the actual needs, and technological innovation and upgrading are imperative. During the transformation of airport drainage ditches, there are many strict conditional restrictions. According to the Measures for the Management of Non-stop Construction at Transport Airports, construction usually needs to be carried out after flight operations or during flight gaps, and the daily construction time is extremely limited, as short as 2 - 5 hours. When constructing drainage ditches within such a tight time window, the traditional cast-in-place concrete drainage ditch construction method exposes obvious drawbacks. The cast-in-place concrete construction process is cumbersome, involving multiple links such as formwork erection, concrete pouring, and curing. The construction efficiency is low, and it is difficult to ensure the construction quality within the limited construction time, increasing the construction difficulty and cost.

[0003] Although prefabricated drainage ditches have improved the standardization of construction to a certain extent, they also have obvious limitations. The installation of prefabricated drainage ditches requires the cooperation of a crane, and the equipment allocation and preparation work are complex. At the same time, the transportation efficiency is low, and the time required for the hoisting process is long, making it very difficult to complete the construction within the limited time of after flight operations / flight gaps and unable to well meet the special requirements of non-stop construction at airports. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a rapid construction method for a fiberglass drainage ditch at an airport without suspending flights.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A rapid construction method for a fiberglass drainage ditch at an airport without suspending flights, the method comprising the following steps:

[0008] Excavate a ditch installation groove, and pour a cushion layer in the ditch installation groove;

[0009] Assemble multiple prefabricated fiberglass reinforced plastic (FRP) drainage ditches in the installation groove of the drainage ditch, and connect the steel trough structures of two adjacent FRP drainage ditches;

[0010] Install a waterproof sealing structure at the connection nodes of two adjacent FRP drainage ditches, and backfill and compact the soil in the area between the installation groove of the drainage ditch and the FRP drainage ditch.

[0011] Furthermore, the prefabricated FRP drainage ditch and the steel trough structure for fixing the FRP drainage ditch, and connecting the FRP drainage ditch and the steel trough structure, include:

[0012] According to the structural dimensions, flow cross-section, length and other information of the drainage ditch, set the dimensions of the prefabricated FRP drainage ditch, and set the steel trough structure for fixing the FRP drainage ditch according to the dimensions of the FRP drainage ditch. Prefabricate the FRP drainage ditch and the steel trough structure, and fixedly install the FRP drainage ditch in the steel trough structure.

[0015] Furthermore, the thickness of the concrete cushion layer is 10 cm, and the flatness and elevation of the cushion layer do not exceed 1 cm.

[0016] Furthermore, after excavating the installation groove of the drainage ditch and pouring a cushion layer in the installation groove of the drainage ditch, arrange multiple steel pipes with a diameter of 4 cm in parallel at a spacing of 1 m on the upper part of the cushion layer, and then place and assemble the FRP drainage ditch in the steel trough structure. The bottom of the steel trough structure contacts the steel pipes and can slide to the designated area. After fixedly connecting the steel trough structures of two adjacent FRP drainage ditches, the steel trough structure can be connected to the steel pipes for positioning and fixing.

[0017] Furthermore, installing a waterproof sealing structure at the connection nodes of two adjacent FRP drainage ditches includes: installing a sealing strip at the connection nodes with smaller gaps, and installing a waterproof coiled material at the connection nodes with larger gaps.

[0018] Furthermore, the lapping length of the waterproof coiled material with two adjacent FRP drainage ditches is not less than 30 cm.

[0019] Furthermore, the waterproof and sealing structure includes a U-shaped sealing partition and a sealing bottom plate. The U-shaped sealing partition includes an outer U-shaped structure and an inner U-shaped structure arranged inside the outer U-shaped structure. The two ends of the outer U-shaped structure are hermetically connected to two adjacent fiberglass gutters through waterproof sealant; the outer side surface of the inner U-shaped structure is hermetically pressed against the inner side surfaces of two adjacent fiberglass gutters; the bottom of the outer U-shaped structure is fixedly connected to the sealing bottom plate, and the upper surface of the sealing bottom plate is hermetically attached to the lower surface of two adjacent fiberglass gutters.

[0020] Furthermore, rubber sealing strips are provided at the joints between the outer U-shaped structure and two adjacent fiberglass gutters; movable seals are installed at the contact points between the two side frames of the inner U-shaped structure and the left and right inner walls of the two fiberglass gutters; a plurality of water passing through holes are arranged side by side on the bottom frame of the inner U-shaped structure.

Detailed implementation manners

[0037] In order to clearly and completely describe the technical solutions in the embodiments of the present invention below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] It should be understood that terms such as "having", "comprising", and "including" as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0039] Example 1

[0040] Please refer to Figures 1-11 , the present invention provides a method for rapid construction of a fiberglass drain ditch at an airport without suspending flights, and the method includes the following steps:

[0041] Precast a fiberglass drain ditch 1 and a steel trough structure for fixing the fiberglass drain ditch 1, and connect the fiberglass drain ditch 1 and the steel trough structure;

[0042] Excavate a drain ditch installation groove and pour a cushion layer in the drain ditch installation groove;

[0043] Assemble multiple precast fiberglass drain ditches 1 in the drain ditch installation groove, and connect the steel trough structures of two adjacent fiberglass drain ditches 1;

[0044] Install a waterproof sealing structure 2 at the connection node of two adjacent fiberglass drain ditches 1, and perform earthwork backfilling and compaction treatment on the area between the drain ditch installation groove and the fiberglass drain ditch 1.

[0045] The working principle and technical effect of the above technical solution are:

[0046] In a rapid construction method of a fiberglass reinforced plastic (FRP) drainage ditch at an airport without suspending flights, there are prefabricated FRP drainage ditches 1 and steel trough structures for fixing. FRP has the characteristics of light weight, corrosion resistance, and relatively high strength, making it suitable for use in the humid and chemically corrosive environment of an airport. The steel trough structure provides a stable fixing and connecting foundation for the FRP drainage ditch 1. Connecting the two in advance facilitates subsequent overall installation, reducing the workload and time of on-site construction. Excavating the installation groove for the drainage ditch provides an installation space for the FRP drainage ditch 1 to ensure the accurate installation position of the drainage ditch. Pouring a cushion layer in the installation groove of the drainage ditch can level the base and disperse the pressure of the drainage ditch, ensuring uniform stress after the installation of the FRP drainage ditch and avoiding damage to the drainage ditch caused by an uneven base; Assembling multiple prefabricated FRP drainage ditches 1 in the installation groove of the drainage ditch and forming a continuous and stable drainage channel for multiple drainage ditches through the steel trough structure connecting adjacent two FRP drainage ditches. Compared with traditional cast-in-place concrete construction, it greatly reduces on-site wet operations and curing time, improving construction efficiency; Installing a waterproof sealing structure 2 at the connection node between adjacent two FRP drainage ditches 1 to prevent water leakage from the connection node, ensuring the tightness and reliability of the drainage system. Backfilling and tamping the area between the installation groove of the drainage ditch and the FRP drainage ditch to fix the FRP drainage ditch in the installation position, enhancing its stability and protecting the drainage ditch from external factors; A rapid construction method of an FRP drainage ditch at an airport without suspending flights. Since most of the work is completed in the prefabrication stage, on-site construction mainly involves assembly and simple processing, with a short construction time. It can make full use of the limited time during the post-flight / flight interval for construction, reducing the impact on the normal operation of the airport and meeting the requirements of the airport's non-stop flight construction management measures; Compared with traditional cast-in-place concrete drainage ditch construction, this method avoids the long on-site concrete pouring and curing process; Compared with assembled drainage ditches, it reduces the crane use time and component transportation links, improving construction efficiency. It can complete more construction tasks within a daily construction time of 2 - 5 hours, accelerating the progress of the airport drainage ditch renovation; In addition, it should be noted that the FRP drainage ditch 1 can only replace the open ditch, vehicles and heavy objects cannot press on it, and it has relatively high requirements for the flatness of the splicing bottom surface.

[0047] The prefabricated FRP drainage ditch 1 and the steel trough structure for fixing the FRP drainage ditch 1, and connecting the FRP drainage ditch 1 and the steel trough structure, including:

[0048] According to information such as the structural dimensions, flowing cross-section, and length of the drainage ditch, set the dimensions of the prefabricated FRP drainage ditch 1, and set the steel trough structure for fixing the FRP drainage ditch 1 according to the dimensions of the FRP drainage ditch 1. Fix and install the FRP drainage ditch 1 in the steel trough structure.

[0049] The technical effects of the above technical solution are as follows: By setting the dimensions of the precast fiberglass drainage ditch and steel trough structure according to the detailed information such as the structural dimensions, flowing cross-section, and length of the drainage ditch, it can ensure that the precast components perfectly match the requirements of the actual airport drainage ditch. After installation, the drainage capacity of the drainage ditch can meet the design standards, effectively discharging the precipitation between the taxiway and apron in the flight area and the treated sewage in the terminal building, avoiding problems such as poor drainage or water overflow. In addition, according to the specific conditions of different airports and the special requirements of drainage ditches in different positions, the dimensions of the precast components can be flexibly adjusted. For example, for areas with a large flow rate, the flowing cross-section can be appropriately increased; for positions with limited space, the length and width of the drainage ditch can be reasonably designed, improving the applicability and versatility of the solution.

[0050] Excavate the installation groove for the drainage ditch and pour a cushion layer in the installation groove for the drainage ditch, including:

[0051] Determine the construction area of the installation groove for the drainage ditch, conduct earth excavation according to the preset dimensions of the installation groove for the drainage ditch, and pour a concrete cushion layer at the bottom of the installation groove for the drainage ditch after excavation. The thickness of the concrete cushion layer is 10 cm, and the flatness and elevation of the cushion layer do not exceed 1 cm. The above settings can effectively ensure the installation accuracy of the subsequent drainage ditch.

[0052] After excavating the installation groove for the drainage ditch and pouring the cushion layer in the installation groove for the drainage ditch, arrange multiple steel pipes with a diameter of 4 cm in parallel at an interval of 1 meter on the upper part of the cushion layer, and then place and assemble the fiberglass drainage ditch 1 inside the steel trough structure. The bottom of the steel trough structure contacts the steel pipes and can slide to the designated area. After fixedly connecting the steel trough structures of two adjacent fiberglass drainage ditches 1, the steel trough structure can be connected to the steel pipes for positioning and fixing.

[0053] The technical effects of the above technical solution are as follows: Steel pipes with a diameter of 4 cm are arranged in parallel on the upper part of the cushion layer. The steel pipes play a role of rolling support. Since the bottom of the steel trough structure contacts the steel pipes and can slide, it makes it easy and labor-saving to move the fiberglass water channel assembled in the steel trough structure to the designated area. Compared with the traditional method of directly dragging or carrying the heavy fiberglass water channel components on the cushion layer, the labor intensity of construction workers is greatly reduced, and the manpower requirement is decreased; The steel pipes are arranged in parallel at an interval of 1 meter, providing accurate guidance for the installation of the fiberglass water channel. Construction workers can accurately slide the water channel along the direction of the steel pipes to the predetermined position, reducing the deviation caused by inaccurate manual handling and positioning, and improving the installation accuracy and efficiency; During the handling and installation process, the steel trough structure is in rolling contact with the steel pipes, avoiding direct friction between the steel trough structure and the cushion layer, reducing the wear of the steel trough structure and the fiberglass water channel, helping to protect the structural integrity of the fiberglass water channel and extending its service life. At the same time, the strength and stability of the steel trough structure are ensured, ensuring that it can effectively fix and support the fiberglass water channel; The fiberglass material is relatively fragile and may be deformed due to uneven stress in the traditional installation method. Through the rolling support of the steel pipes, the steel trough structure and the fiberglass water channel are evenly stressed during the movement process, avoiding deformation problems caused by excessive local stress, ensuring the quality and drainage performance of the water channel. After fixedly connecting the steel trough structures of two adjacent fiberglass water channels, then connecting the steel trough structure with the steel pipes for positioning and fixing. This step-by-step connection method makes the connection more firm and reliable. The steel pipes not only play a guiding and supporting role during the installation process but also become a part of the fixed structure subsequently, enhancing the stability and integrity of the entire drainage system.

[0054] Install a waterproof sealing structure 2 at the connection node of two adjacent fiberglass water channels 1, including: installing a sealing strip at the connection node with a smaller gap, and installing a waterproof coiled material at the connection node with a larger gap. The overlapping length of the waterproof coiled material with two adjacent fiberglass water channels 1 is not less than 30 cm.

[0055] This solution uses sealing rubber strips and waterproof coiled materials respectively to deal with different situations of smaller and larger gaps, which reflects strong pertinence. The sealing rubber strip has good elasticity and viscosity, can tightly fill smaller gaps, and effectively prevent water penetration; while the waterproof coiled material is suitable for larger gaps, and it has strong ductility and waterproof performance, which can better cover and seal larger gaps, so as to ensure good waterproof effect under various gap conditions. The sealing rubber strip is installed at the connection nodes with smaller gaps and can closely fit with the fiberglass water channel to form a continuous sealing barrier. It can prevent rainwater, sewage, etc. from leaking out of the water channel through the gaps, avoid erosion of the surrounding soil and airport infrastructure, ensure the normal operation of the drainage system, and extend the service life of the water channel and its surrounding facilities. For the connection nodes with larger gaps, the use of waterproof coiled materials further enhances the reliability of waterproofing. It is stipulated that the overlapping length of the waterproof coiled material with the adjacent two fiberglass water channels is not less than 30 cm, which enables the waterproof coiled material to form a large enough coverage area at the connection node and effectively prevent water from bypassing the connection node and entering the outside of the water channel. The large-area overlap can resist the scouring and penetration of water flow, and can maintain good waterproof performance even under high water pressure.

[0056] Embodiment 2

[0057] Please refer to Figures 2-11 , the waterproof and sealing structure 2 includes: a U-shaped sealing partition 100 and a sealing bottom plate 200. The U-shaped sealing partition 100 includes: an outer U-shaped structure 101 and an inner U-shaped structure 102 arranged inside the outer U-shaped structure 101. The two ends of the outer U-shaped structure 101 are hermetically connected to the adjacent two fiberglass water channels 1 through waterproof sealant; the outer side surface of the inner U-shaped structure 102 is hermetically pressed on the inner side surfaces of the adjacent two fiberglass water channels 1; the bottom of the outer U-shaped structure 101 is fixedly connected to the sealing bottom plate 200, and the upper surface of the sealing bottom plate 200 is hermetically attached to the lower surfaces of the adjacent two fiberglass water channels 1.

[0058] The working principle and technical effect of the above technical solution are: the two ends of the outer U-shaped structure 101 are hermetically connected to the adjacent two fiberglass water channels 1 through waterproof sealant, forming a first external sealing line of defense, which can effectively prevent water from penetrating into the fiberglass water channel 1 from the outside through the connection node; the outer side surface of the inner U-shaped structure 102 is hermetically pressed on the inner side surfaces of the adjacent two fiberglass water channels 1, forming a second sealing line of defense inside the fiberglass water channel 1 to prevent water from leaking out from the inside; the upper surface of the sealing bottom plate 200 is hermetically attached to the lower surfaces of the adjacent two fiberglass water channels 1, adding bottom sealing and further preventing water from penetrating from the bottom; the multiple sealing lines of defense greatly improve the reliability of waterproofing and ensure that there is no leakage at the connection node.

[0059] The bottom of the outer U-shaped structure 101 is fixedly connected to the sealing bottom plate 200. This structural design makes the waterproof sealing structure 2 form an integral whole, enhancing its own stability. At the same time, it is closely connected to the adjacent fiberglass drainage ditch 1, connecting the adjacent fiberglass drainage ditches 1 together, improving the integrity and structural strength of the entire drainage system; when subjected to external forces (such as water flow impact, ground settlement, etc.), it can jointly bear the load, reduce damage caused by uneven local stress, and thus improve the durability and stability of the entire structure.

[0060] Rubber sealing strips are provided at the joints of the outer U-shaped structure 101 and the adjacent two fiberglass drainage ditches 1; movable seals 400 are installed at the contacts between the two side frames of the inner U-shaped structure 102 and the left and right inner walls of the two fiberglass drainage ditches 1; a plurality of water passing through holes 103 are arranged side by side on the bottom frame of the inner U-shaped structure 102.

[0061] Rubber sealing strips are provided at the joints of the outer U-shaped structure 101 and the adjacent two fiberglass drainage ditches 1, and rubber is elastic. When the outer U-shaped structure 101 is connected and installed with the fiberglass drainage ditch 1, the rubber sealing strip is squeezed and deformed, filling the tiny gaps between the outer U-shaped structure 101 and the fiberglass drainage ditch 1. Its own elasticity enables it to closely fit on the contact surfaces of the two, forming a barrier to prevent water leakage, and relying on the waterproof characteristics and sealing and fitting effects of the rubber material to prevent water from seeping out at the joint. A plurality of water passing through holes 103 are arranged side by side on the bottom frame of the inner U-shaped structure 102. When water flows through the connection node of the adjacent fiberglass drainage ditches, the water passing through holes play a role in guiding the water flow. Water can flow smoothly between different fiberglass drainage ditches through these through holes, ensuring the normal drainage function of the drainage system and avoiding water flow blockage or water accumulation caused by the blockage at the connection node.

[0062] Two airbag grooves are provided on the upper surface of the sealing bottom plate 200. The two airbag grooves are connected by a transverse pipe groove horizontally arranged on the sealing bottom plate 200. The transverse pipe groove is connected to a longitudinal pipe groove longitudinally penetrating the bottom frames of the U-shaped structure and the outer U-shaped structure 101. An inverted T-shaped pipe body 300 is installed in the inverted T-shaped pipe groove formed between the transverse pipe groove and the longitudinal pipe groove. The two ends of the inverted T-shaped pipe body 300 are respectively connected to the inflatable airbags 301 fixed in the two airbag grooves. One end of the inverted T-shaped pipe body 300 extending above the bottom frame of the inner U-shaped structure 102 is fixed with a gas storage tank 302. A piston body 303 is slidably sealed in the gas storage tank 302. A compression spring 304 is provided between the lower surface of the piston body 303 and the bottom surface of the gas storage tank 302. The piston body 303 is connected to a piston rod 305 slidably arranged on the upper end cover of the gas storage tank 302. A cross bar 306 fixedly connected to the top of the piston rod 305 is slidably arranged in the strip groove of the chute frame 308 on the lower surface of the inclined baffle 307. One end of the inclined baffle 307 is rotatably connected to the inner bottom surface of a fiberglass drainage ditch 1 through a hinge shaft.

[0063] When the water flow velocity in the FRP water channel 1 is relatively fast and the flow rate is relatively large, multiple water passing through holes 103 cannot meet the drainage and water passing requirements. The contact area between the accumulated water and the upper surface of the inclined baffle 307 gradually increases, generating pressure on the upper surface of the inclined baffle 307, which can cause the inclined baffle 307 to rotate downward around the axis of the hinge shaft. When the inclined baffle 307 moves downward, it drives the chute frame 308 to flip downward. When the chute frame 308 flips downward, it changes its contact position with the cross bar 306 and drives the cross bar 306 to move downward. When the cross bar 306 moves downward, it presses the piston body 303 to slide downward in the gas storage tank 302 through the piston rod 305 and compresses the compression spring 304. At the same time, the gas in the gas storage tank 302 is pressed into the inverted T-shaped pipe body 300 or compressed, and enters the inflatable air bags 301 in the two air bag grooves through the inverted T-shaped pipe body 300, causing the inflatable air bags 301 to expand and fit more tightly against the lower surface of the FRP water channel 1, improving the sealing effect of the FRP water channel 1 and the assembly connection effect between two adjacent FRP water channels 1;

[0064] In the above technical solution, when the water flow velocity in the FRP drainage ditch 1 is relatively fast and the flow rate is relatively large, and multiple water passing through holes cannot meet the drainage requirements, the water flow generates pressure on the inclined baffle 307 to make it rotate, prompting the gas in the gas storage tank to be pressed into the inflatable airbag 301, causing the inflatable airbag 301 to expand. The expanded inflatable airbag 301 can fit more closely to the lower surface of the FRP drainage ditch, greatly improving the sealing effect of the FRP drainage ditch 1, ensuring the waterproof performance of the drainage system, reducing the waste of water resources and the impact on the surrounding environment. After the inflatable airbag 301 expands, while enhancing the sealing, it can also improve the assembly connection effect between two adjacent FRP drainage ditches 1. The acting force generated by the close fit of the inflatable airbag 301 can make the adjacent FRP drainage ditches 1 more firmly connected, reducing the problem of connection loosening caused by factors such as water flow impact and vibration, helping to improve the structural stability of the entire drainage system, extending the service life of the system, and reducing the maintenance cost; this solution can automatically adjust the sealing and connection states according to the actual situation of the water flow without manual intervention. When the water flow situation changes, the inclined baffle 307 can promptly sense and control the inflatable airbag 301 through a series of mechanical structures. This intelligent response mechanism enables the drainage system to better adapt to different working conditions, improving the reliability and operating efficiency of the system; in addition, during the process of the inclined baffle 307 flipping due to water flow impact, the gas in the compression spring 304 and the gas storage tank 302 plays a buffering role, which can reduce the impact force on components such as the inclined baffle 307, the piston rod 305, and the piston body 303, avoiding damage to these components due to the instantaneous huge impact force, extending the service life of each component, reducing the risk of system failure caused by component damage, and making the flipping movement of the inclined baffle 307 more stable, avoiding violent shaking or sudden movement caused by water flow impact, helping to maintain the stable operation of the entire drainage system, reducing the adverse effects on other components caused by the unstable movement of the inclined baffle, and ensuring the normal drainage function of the drainage system; through buffering, the gas is slowly and steadily pressed into the inflatable airbag, making the inflation process of the inflatable airbag more uniform and controllable, avoiding the situation of over-inflation or uneven inflation of the airbag caused by the rapid and large influx of gas, thereby ensuring that the inflatable airbag can better fit the lower surface of the FRP drainage ditch and achieving good sealing and connection effects; when the water flow velocity is small and the flow rate decreases, the compression spring 304 resets, causing the inclined baffle 307 to reset.

[0065] The inside of the inclined baffle 307 is provided with a diversion chamber, and the diversion chamber is communicated with a triangular feed port 309 arranged on the upper surface of the inclined baffle 307. The opening of the triangular feed port 309 is arranged close to the hinge shaft. A triangular flow-condensing chamber is arranged in the triangular feed port 309. The dimension of the triangular flow-condensing chamber at one end close to the hinge shaft is larger than that at the end far from the hinge shaft. One end of the inclined baffle 307 far from the hinge shaft is provided with an outflow port 310 facing another fiberglass water channel 1. The upper part of the outflow port 310 is communicated with the diversion chamber. A first horizontal shaft 311 is rotatably connected in the outflow port 310. Above the rotating impeller 312 fixedly connected to the middle of the first horizontal shaft 311 is located at the outflow end of the diversion chamber. One end of the inner U-shaped structure 102 far from the hinge shaft is provided with a horizontal guide rod 313. The front end of the horizontal guide rod 313 is slidably arranged in the horizontal chute of the movable scraping frame 314. The movable scraping frame 314 is slidably arranged on the inner bottom surface of the fiberglass water channel 1. The front end of the movable scraping frame 314 is rotatably connected to a second horizontal shaft 315. The second horizontal shaft 315 and the first horizontal shaft 311 are connected by two oppositely arranged bearing frames 316. The first pulleys at both ends of the first horizontal shaft 311 are connected to the second pulleys at both ends of the second horizontal shaft 315 through a first synchronous belt. A front cleaning roller 317 is fixedly arranged on the second horizontal shaft 315. Two third wheel shafts 318 are rotatably arranged at the rear end of the movable scraping frame 314 relatively. The synchronous wheels on the two third wheel shafts 318 are connected to the synchronous wheel on the second horizontal shaft 315 through a second synchronous belt. Rear cleaning rollers 319 are fixedly arranged on the third wheel shafts 318.

[0066] A diversion chamber is provided inside the inclined baffle 307. The diversion chamber is communicated with the triangular feed ports 309 arranged on the upper surface of the inclined baffle 307. When the water flow velocity in the fiberglass water channel 1 is relatively fast and the flow rate is relatively large, the water flow converges through the multiple triangular feed ports 309 and enters the diversion chamber of the inclined baffle 307, and then is output through the outlet 310. The water flow output through the outlet 310 impacts the rotating impeller 312, causing the rotating impeller 312 to rotate and drive the first horizontal shaft 311 to rotate. When the first horizontal shaft 311 rotates, it can drive the first belt pulley to rotate. The first belt pulley drives the second belt pulley to rotate through the first synchronous belt, thereby controlling the rotation of the second horizontal shaft 315. When the second horizontal shaft 315 rotates, it can drive the front cleaning roller 317 to rotate. Moreover, the synchronous pulley on the second horizontal shaft 315 rotates to drive the synchronous pulley on the third shaft 318 to rotate through the second synchronous belt, so that the third shaft 318 rotates and drives the rear cleaning roller 319 to rotate. The bottom surface of the connection of the two fiberglass water channels 1 is cleaned by the front cleaning roller 317 and the rear cleaning roller 319, reducing the probability of impurities accumulating at the fiberglass water channel 1 and ensuring the subsequent water passing effect of the multiple water passing through holes 103. And when the inclined baffle 307 flips with the water flow rate, it can also drive one end of the bearing frame 316 to move. The other end of the bearing frame 316 drives the movable scraping frame 314 to slide at the front end of the horizontal guide rod 313, thereby changing the contact position between the movable scraping frame 314 and the bottom surface of the fiberglass water channel 1, thus improving the effect of scraping stubborn dirt.

[0067] The above solution has the following advantages in many aspects: efficiently utilizing the water flow energy to achieve automatic cleaning. When the water flow velocity in the fiberglass water channel 1 is relatively fast and the flow rate is relatively large, the water flow converges through the triangular feed ports 309 and enters the diversion chamber, and then impacts the rotating impeller 312 through the outlet to make it rotate, converting the kinetic energy of the water flow into mechanical energy, driving a series of transmission components to operate, and further driving the front cleaning roller and the rear cleaning roller to clean the bottom surface of the connection of the two fiberglass water channels; no additional power equipment is required, and the automatic cleaning function is completely realized relying on the energy of the water flow itself, reducing energy consumption and operation costs; in addition, the greater the water flow rate, the stronger the impact force on the rotating impeller, making the rotation speed of the cleaning roller faster and the cleaning effect better. This means that the system can automatically adjust the cleaning intensity according to the actual water flow situation, achieving efficient and intelligent cleaning operations and improving the resource utilization efficiency. The rotation of the front cleaning roller and the rear cleaning roller can timely clean the impurities on the bottom surface of the connection of the fiberglass water channels, reducing the probability of impurity accumulation, ensuring the water passing effect of the multiple water passing through holes, avoiding the problem of poor drainage caused by the blockage of the water passing through holes by impurities, ensuring the normal operation of the drainage system, and reducing potential safety hazards such as waterlogging and flooding caused by drainage obstruction.

[0068] When the inclined baffle rotates with the water flow rate, it drives the bearing frame to move, and then makes the movable scraper slide at the front end of the horizontal guide rod, changing the contact position between the movable scraper and the bottom surface of the fiberglass water channel. The combined rotation cleaning of the front cleaning roller and the rear cleaning roller and the sliding scraping of the movable scraper achieve multi-angle and all-round cleaning, which can more effectively remove stubborn dirt and improve the cleaning effect; the change in the position of the movable scraper enables it to adapt to different water flow conditions and dirt distributions, and can maintain good cleaning performance even under complex working conditions, enhancing the adaptability and reliability of the system.

[0069] The movable seal 400 includes: a pressing plate 401 slidably sealed in the side groove of the inner U-shaped structure 102 side frame, multiple tension springs 402 fixedly connected between the pressing plate 401 and the inner side surface of the side groove of the side frame, a pressing rubber 403 provided at the contact between the pressing plate 401 and the inner walls of the two fiberglass water channels 1, a horizontal slider 404 on the pressing plate 401 slidably disposed in the horizontal through hole of the inner U-shaped structure 102 side frame, and an inclined pressing surface 405 inside the horizontal slider 404 located below the lower surface of the inclined baffle 307; the inner ends of the horizontal sliders 404 of two adjacent movable seals 400 are fixedly connected with a horizontal connecting arm 406.

[0070] In actual use, the inclined pressing surface 405 inside the horizontal slider 404 is located below the lower surface of the inclined baffle 307. When the inclined baffle 307 rotates downward to a preset position, that is, when the water flow rate is large, it can contact the inclined pressing surface 405 inside the horizontal slider 404, exerting a pressure on the inclined pressing surface 405 of the horizontal slider 404, so that the horizontal slider 404 slides outward and drives the pressing plate 401 and the pressing rubber 403 to tightly press against the inner wall of the fiberglass water channel 1, and stretches the tension springs 402, effectively preventing water from leaking from the contact between the inner wall of the fiberglass water channel and the side frame of the inner U-shaped structure. After the water flow rate decreases, the pressing plate 401 resets under the elastic force of the tension springs 402.
