Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to a prefabricated canal construction process. Background Technology

[0002] Canals are widely used in water conservancy projects, primarily for farmland irrigation, water supply and drainage, flood control, and supplying domestic water to remote mountainous areas. In ethnic minority areas located in mountainous and hilly regions, canals are often constructed using precast cement components or on-site concrete construction to solve the problems of drinking water for people and livestock and irrigation for crops. Due to steep terrain, rugged roads, and in many places, no roads at all, the transportation of building materials and semi-finished components poses significant challenges and manpower shortages.

[0003] On-site concrete construction uses cement and sand, requiring frequent handling of large quantities of materials. Construction is difficult in steep mountainous areas, resulting in high transportation costs and long construction periods. Furthermore, concrete products are brittle materials with poor earthquake resistance and water conveyance capacity. Concrete canal walls are prone to moss growth, causing water pollution and high maintenance costs.

[0004] Traditional precast concrete components have three main problems: 1) Traditional precast concrete components have a U-shaped bottom, which makes installation inconvenient and aligning the two ends of the components is difficult; 2) Precast concrete components are precast as a whole, which makes them heavy and difficult to transport. Summary of the Invention

[0005] This invention provides a prefabricated water channel construction process, which aims to solve the problems of complex construction and short lifespan of concrete-made water channels in the prior art, and high installation difficulty and transportation difficulties of water channels made of cement precast components.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A prefabricated irrigation canal construction process is provided, including the following steps:

[0008] S1: Excavation of waterways;

[0009] S2: Construct a transportation system above the waterway along the direction of waterway extension;

[0010] S3: Manufacturing prefabricated components;

[0011] S4: Use the transport system to move the prefabricated component to a predetermined position on the waterway;

[0012] S5: Repeat S3 to S4 above until all the prefabricated parts have been transported;

[0013] S6: Join adjacent prefabricated components to form a spliced ​​water channel.

[0014] In one possible implementation, the transportation system includes:

[0015] A guide rail is provided above the waterway and along the extension direction of the waterway;

[0016] Multiple support components are arranged at intervals along the extension direction of the waterway. Each set of support components has a hanger rod, which spans the upper part of the guide rail along the width direction of the waterway and is connected to the guide rail; and

[0017] The transport vehicle includes a vehicle body, a transfer rod located at the front end of the vehicle body, and a connecting rod located at the top of the vehicle body. The transfer rod can connect to the prefabricated component, and the top of the connecting rod is provided with a roller, which rolls in cooperation with the guide rail.

[0018] In one possible implementation, the support assembly further includes two support frames, which are symmetrically distributed and fixed on both sides of the waterway, and the hanger is connected to the top of the two support frames.

[0019] In one possible implementation, the guide rail has a guide groove that extends along the extension direction of the guide rail;

[0020] The roller's axis of rotation is set in a horizontal direction, and the roller rolls into contact with the guide groove.

[0021] In one possible implementation, the bottom of the vehicle body has omnidirectional wheels;

[0022] The vehicle body is provided with a drive mechanism on the side opposite to the transfer rod, and the drive mechanism is used to drive the vehicle body to move.

[0023] In one possible implementation, the prefabricated component includes:

[0024] A U-shaped panel with an upward opening;

[0025] Two upper pressure plates are respectively disposed at the top ends of the two extended walls of the U-shaped plate. The upper pressure plates extend out of the U-shaped plate in the front-rear direction. The upper pressure plates are offset from the rear ends of the U-shaped plate to form an overlapping groove at the top of the U-shaped plate. The overlapping groove overlaps and engages with the upper pressure plate in the adjacent precast component.

[0026] A horizontal section is located at the bottom of the U-shaped plate, and the bottom of the horizontal section is flush with the bottom of the waterway.

[0027] In one possible implementation, the upper pressure plate is provided with a through mounting hole, and the top of the extension wall of the U-shaped plate is provided with a corresponding fixing hole. The upper pressure plate and the U-shaped plate are fixedly connected by fasteners that pass through the mounting hole and the fixing hole.

[0028] In one possible implementation, a fixing assembly is provided between the prefabricated component and the transfer rod, the fixing assembly comprising:

[0029] Three leveling frames are respectively attached and fixed to the inner bottom and inner side surfaces of the U-shaped plate;

[0030] A drive body is detachably connected to the transfer rod. The drive body has rotating rods that correspond one-to-one with the three leveling frames. Each rotating rod is fitted with a limiting cylinder, which is connected to the drive body. The inner wall of the limiting cylinder has a through-groove.

[0031] Three transmission rods are respectively connected between the corresponding limiting cylinder and the corresponding leveling frame. The rotating rod is a screw rod. The transmission rod has a threaded groove on the side facing the rotating rod. The threaded groove and the rotating rod lead screw are engaged. The outer circumference of the transmission rod has a limiting protrusion along its own length direction. The limiting protrusion is inserted into the limiting groove.

[0032] In one possible implementation, one end face of the U-shaped plate forms a snap-fit ​​protrusion, and the other end face forms a snap-fit ​​groove, the snap-fit ​​groove and the snap-fit ​​protrusion in the adjacent preform are inserted into each other.

[0033] In one possible implementation, a water-stop sealing layer is filled between the snap-fit ​​groove and the corresponding snap-fit ​​protrusion.

[0034] The prefabricated water channel construction process provided by this invention offers a hoisting method compared to existing technologies. A transportation system is built over the waterway to move prefabricated components to preset positions. Multiple prefabricated components are then sequentially assembled to form the water channel. During this process, the transportation system spans the entire waterway. Prefabricated components are manufactured before hoisting, avoiding on-site construction and reducing the number of material handling operations, thus saving construction time. Furthermore, the method of assembling multiple prefabricated components into a water channel allows for convenient movement of individual components. The transportation system enables rapid transport to designated locations, facilitating the installation and fixing of prefabricated components and accelerating the construction efficiency of the water channel.

[0057] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0058] It should be noted that the terms "length", "width", "height", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "head", and "tail" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0059] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0061] Please refer to the following: Figures 1 to 13 The prefabricated water channel construction process provided by this invention will now be described. The prefabricated water channel construction process includes the following steps: S1: excavating the waterway 1; S2: constructing a transportation system 2 above the waterway 1 along its extension direction; S3: manufacturing prefabricated components 3; S4: using the transportation system 2 to move the prefabricated components 3 to a predetermined position on the waterway 1; S5: repeating S3 to S4 until all prefabricated components 3 have been transported; S6: splicing adjacent prefabricated components 3 to form a spliced ​​water channel.

[0062] It should be noted that precast component 3 is a cement precast component.

[0063] It should be noted that the transport system 2 spans the entire waterway 1, and the precast component 3 moves along the extension direction of the waterway 1 under the action of the transport system 2. The transport system 2 only transports the precast component 3.

[0064] It should be understood that the water channel in this application is a prefabricated water channel, which is composed of multiple prefabricated components 3 spliced ​​together in sequence.

[0065] Compared with the prior art, the prefabricated water channel construction process provided in this embodiment offers a hoisting method. A transportation system 2 is built on the waterway 1, and prefabricated components 3 are moved to preset positions through the transportation system 2. Then, multiple prefabricated components 3 are sequentially spliced ​​to form a water channel. During this process, the transportation system 2 spans the entire waterway 1. The prefabricated components 3 are manufactured first and then hoisted, avoiding on-site construction and only transporting the prefabricated components 3, reducing the number of times materials are handled and saving construction time. In this application, multiple prefabricated components 3 are spliced ​​to form a water channel, and individual prefabricated components 3 are easy to move. With the help of the transportation system 2, they can be quickly transported to the designated location, facilitating the installation and fixing of the prefabricated components 3 and accelerating the construction efficiency of the water channel.

[0066] In some embodiments, see Figure 1 The transportation system 2 includes multiple support components 21, guide rails 22, and a transport vehicle 23. The guide rails 22 are located above the waterway 1 and are arranged along the extension direction of the waterway 1. The multiple support components 21 are arranged at intervals along the extension direction of the waterway 1. Each set of support components 21 has a boom 211, which spans the upper part of the guide rail 22 along the width direction of the waterway 1 and is connected to the guide rail 22. The transport vehicle 23 includes a vehicle body 231, a transfer rod 233 located at the front end of the vehicle body 231, and a connecting rod 234 located at the top of the vehicle body 231. The transfer rod 233 can connect to the precast component 3. The top of the connecting rod 234 is provided with a roller 235, which rolls in cooperation with the guide rail 22.

[0067] The transportation system 2 provided in this embodiment is simple to manufacture and requires little engineering work. The precast components 3 are prefabricated in advance. The transportation system 2 only needs to move the precast components 3 to the preset position, eliminating the need for simultaneous material transport and pouring as in existing concrete pouring methods. This eliminates the need for solidification and cooling time, significantly shortening the construction period. In this application, the precast components 3 are lifted to the preset position by the transport vehicle 23. After the transport vehicle 23 returns, it lifts the next precast component 3, greatly reducing the number of transport operations. The transport vehicle 23 moves along the extension direction of the waterway 1 under the action of the guide rail 22, accurately lifting the precast components 3 to the preset position. This facilitates installation and rotation, improving the alignment accuracy of the precast components 3. The connecting rod 234 connects to the transport vehicle 23. After the roller 235 and the guide rail 22 roll in cooperation, the roller 235 drives the transport vehicle 23 to change direction, preventing the transport vehicle 23 from causing the precast components 3 to deviate from the extension direction of the waterway 1, ensuring that the precast components 3 can fall normally to the preset position. The boom 211 provides a fixed position for the guide rail 22. The guide rail 22 is connected to multiple booms 211, which ensures the extension direction of the guide rail 22 and improves its stability.

[0068] In some embodiments, see Figure 2 The support assembly 21 also includes two support frames 212, which are symmetrically distributed and fixed on both sides of the waterway 1. The boom 211 is connected to the top of the two support frames 212. The support frames 212 are located at both ends in the width direction of the waterway 1, providing support for the boom 211 and keeping it horizontal. This ensures the normal installation of the guide rail 22, thereby ensuring that the guide rail 22 guides the roller 235 to move, and ultimately allows the transport vehicle 23 to move along the extension direction of the guide rail 22.

[0069] It should be noted that multiple support frames 212 are adaptively connected to the ground so that multiple hangers 211 are all at the same horizontal height, allowing the hangers 211 to be properly connected to the guide rail 22.

[0070] In some embodiments, see Figure 3The guide rail 22 has a guide groove 221 that extends along the extension direction of the guide rail 22; the roller 235 has its shaft arranged horizontally, and the roller 235 rolls in cooperation with the guide groove 221. The guide groove 221 provides rolling space for the roller 235 and guides the movement of the roller 235.

[0071] As a specific way of cooperating between the guide groove 221 and the roller 235, the guide rail 22 has roller grooves on its two ends extending in opposite directions, forming the guide groove 221. The top of the connecting rod 234 is connected to a U-shaped rod, and rollers 235 are respectively provided on the two arms of the U-shaped rod. The two rollers 235 are arranged opposite to each other, and the roller groove and the roller 235 roll together.

[0072] In practice, guide rail 22 is an I-shaped component.

[0073] As another specific way of cooperating between the guide groove 221 and the roller 235, one of the two ends of the guide rail 22 extending in the opposite direction is provided with a roller groove, which forms the guide groove 221. The top end of the connecting rod 234 is provided with a roller 235, and the roller groove and the roller 235 are in rolling cooperation.

[0074] As another specific way in which the guide groove 221 and the roller 235 are coupled, see [reference needed]. Figure 9 The guide rail 22 is a rectangular steel rail with an opening on the lower side. The rectangular steel rail has two guide grooves 222 with openings in the horizontal direction and opposite opening directions. A guide groove 221 is formed between the two guide grooves 222. The top of the connecting rod 234 is connected to two rollers 235. The rollers 235 correspond one-to-one with the guide grooves 222, and the rollers 235 and the corresponding guide grooves 222 roll in cooperation.

[0075] In some embodiments, see Figure 1 The vehicle body 231 has casters 236 at its bottom; a drive mechanism 232 is provided on the side of the vehicle body 231 opposite to the transfer rod 233, which is used to drive the vehicle body 231 to move. The drive mechanism 232 can push the vehicle body 231 to move forward or backward, so that the vehicle body 231 can drive the transfer rod 233 to move along the waterway 1, thereby transferring the prefabricated component 3 to the preset position for installation. The casters 236 can ensure that the vehicle body 231 can turn under the action of the connecting rod 234, so that the vehicle body can move along the extension direction of the waterway 1, and the prefabricated component 3 can be transported to the preset position normally.

[0076] As another embodiment of the assembly of connecting rod 234 and vehicle body 231, see [reference]. Figure 10The bottom end of the connecting rod 234 passes through the vehicle body 231 and is connected to a caster wheel 236, which in turn is connected to wheels. The connecting rod 234 rotates around its own axis under the drive of the roller 235, and the caster wheel 236 can turn with the rotation of the connecting rod 234, thereby changing the direction of movement of the vehicle body 231.

[0077] In practice, the transfer rod 233 is mounted on the vehicle body 231 in a height-adjustable manner, which can drive the precast component 3 to rise and fall, facilitating the installation of the precast component 3.

[0078] In some embodiments, see Figure 4 The precast component 3 includes an upward-opening U-shaped plate 31, two upper pressure plates 32, and a horizontal section 33. The two upper pressure plates 32 are respectively located at the top of the two extended walls of the U-shaped plate 31. The upper pressure plates 32 extend out of the U-shaped plate 31 in the front-rear direction. The upper pressure plates 32 and the rear end of the U-shaped plate 31 are staggered to form an overlapping groove 313 at the top of the U-shaped plate 31. The overlapping groove 313 overlaps and engages with the upper pressure plate 32 in the adjacent precast component 31. The horizontal section 33 is located at the bottom of the U-shaped plate 31, and the bottom of the horizontal section 33 is flush with the bottom of the waterway 1.

[0079] It should be noted that the front-back direction refers to the distance from the end face of the U-shaped plate 31 away from the extension direction of the waterway 1 to the end face of the U-shaped plate 31 along the extension direction of the waterway 1. In the actual transfer process, the front-back direction is parallel to the extension direction of the waterway.

[0080] The prefabricated component 3 provided in this embodiment has a simple structure. The U-shaped plate 31 itself has high structural strength and can fill the waterway 1, forming a water flow space inside. The upper pressure plate 32 can be placed on both sides of the waterway 1 and compact the two connected U-shaped plates 31, facilitating the assembly of multiple U-shaped plates 31 and making the formed water channel structure stable. The horizontal section 33 abuts against the waterway 1, making the upper surfaces of the two walls of the U-shaped plate 31 flush, thus making the installation of the U-shaped plate 31 convenient.

[0081] As a specific assembly method of the horizontal section 33 and the U-shaped plate 31, the horizontal section 33 and the U-shaped plate 31 are integrally formed.

[0082] As another specific assembly method for the horizontal section 33 and the U-shaped plate 31, see [reference needed]. Figure 11 The horizontal section 33 includes a horizontal plate 35 and two oppositely arranged connecting plates 36. The horizontal plate 35 is located between the two connecting plates 36. The connecting plates 36 and the U-shaped piece 31 are connected together by threaded fasteners. The connecting plates 36 and the horizontal plate 35 enclose and form the bottom fixing space of the U-shaped plate 31.

[0083] In some embodiments, see Figure 6The upper pressure plate 32 has a through mounting hole 321, and the top of the extension wall of the U-shaped plate 31 has a corresponding fixing hole 314. The upper pressure plate 32 and the U-shaped plate 31 are fixedly connected by fasteners 34 that pass through the mounting hole 321 and the fixing hole 314. The fasteners 34 connect the upper pressure plate 32 and the U-shaped plate 31 together, improving the structural strength of the precast component 3. The fasteners 34 are threaded to the mounting hole 321 and the fixing hole 314 sequentially from top to bottom, making disassembly and disassembly convenient and facilitating the replacement of the upper pressure plate 32 by the staff, thus making maintenance convenient.

[0084] In practice, the mounting hole 321 is provided with a mounting groove, which is connected to the mounting hole 321. The inner diameter of the mounting groove is larger than the inner diameter of the mounting hole 321. The fastener 34 is a bolt. When the bolt body is threadedly engaged with the mounting hole 321 and the fixing hole, the bolt nut is located in the mounting groove. The mounting groove ensures that the fastener will not protrude from the upper pressure plate 32, thus ensuring the top of the prefabricated component 3 is flush and improving the safety of the spliced ​​water channel.

[0085] It should be noted that, for reference Figure 6 The U-shaped plate 31 has an assembly hole 315 at the position corresponding to the overlapping groove 313. The adjacent upper pressure plate 32 forms a second mounting hole 322 corresponding to the assembly hole. When two adjacent U-shaped plates 31 are spliced ​​together, the second mounting hole 322 and the assembly hole 315 are aligned vertically and fixed by fasteners 34. After two adjacent prefabricated parts 3 are overlapped, the workers install fasteners in the assembly hole 315 and the second mounting hole 322 to further fix the adjacent prefabricated parts 3 and increase the structural strength of the assembled water channel.

[0086] In some embodiments, see Figure 7 and Figure 8 A fixing assembly 4 is provided between the precast component 3 and the transfer rod 233. The fixing assembly 4 includes three leveling frames 41, a drive body 42, and three transmission rods 43. Three leveling frames 41 are respectively attached and fixed to the inner bottom and inner side surfaces of the U-shaped plate 31; the drive body 42 is detachably connected to the transfer rod 233. The drive body 42 has rotating rods 421 that correspond one-to-one with the three leveling frames 41. The rotating rods 421 are fitted with limiting cylinders 422. The limiting cylinders 422 are connected to the drive body 42. The inner wall of the limiting cylinders 422 is provided with a limiting groove 423 that runs through the front and back; three transmission rods 43 are respectively connected between the corresponding limiting cylinders 422 and the corresponding leveling frames 41. The rotating rods 421 are screws. The transmission rods 43 are provided with threaded grooves 431 on the side facing the rotating rods 421. The threaded grooves 431 and the rotating rods 421 are screw-fitted. The outer periphery of the transmission rods 43 is provided with limiting protrusions 432 along its own length direction. The limiting protrusions 432 and the limiting grooves 423 are inserted into each other.

[0087] It should be noted that the rotating rod 421 and the driving body 42 are connected by a gear structure, and the driving body 42 can drive the rotating rod 421 to rotate along its own axis.

[0088] It should be noted that the driving body 42 is a driving motor, which has multiple output shafts, and the output shafts correspond one-to-one with the corresponding leveling frame 41; or a driving component integrating three driving motors can be used, with the output shafts of the three driving motors facing the three inner sides of the U-shaped plate 31 respectively.

[0089] The fixing component 4 provided in this embodiment has a simple structure and uses few parts. The driving body 42 drives the rotating rod 421 to rotate. The rotating rod 421 is a screw, which drives the transmission rod 43 to move closer to or away from the driving body 42 through the lead screw principle. The limiting protrusion 432 and the limiting groove 423 are inserted and matched, so that the transmission rod 43 will not rotate, ensuring that the leveling frame 41 can stably connect to the U-shaped plate 31 and ensuring the adsorption effect. The fixing component 4 does not have a complicated mating structure, which reduces the cost of use.

[0090] In practice, the leveling frame 41 includes a leveling body and multiple leveling supports. The multiple leveling supports are radially and evenly distributed around the leveling body, with the leveling supports 412 fitting against the inner surface of the U-shaped plate 31. Reinforcing ribs are provided between the leveling supports and the leveling body.

[0091] In practice, the leveling frame 41 is adsorbed and connected to the inner surface of the U-shaped plate 31. A vacuum suction cup is provided on the side of the leveling frame 41 away from the transmission rod 43. When the leveling frame 41 is pressed against the inner surface of the U-shaped plate 31, the vacuum suction cup discharges the internal air and presses the U-shaped plate 31 tightly, so that the leveling frame 41 and the U-shaped plate 31 are fixedly connected together.

[0092] As another embodiment of the assembly of the leveling frame 41 and the U-shaped plate 31, the leveling frame 41 is provided with a leveling hole that runs through its own thickness direction, and the inner wall of the U-shaped plate 31 is provided with a leveling groove corresponding to the leveling hole. The leveling hole and the leveling groove are connected by bolts in sequence and threaded to the leveling groove so that the leveling frame 41 and the U-shaped plate 31 are connected together.

[0093] As another implementation of the fixed component 4, see [link to documentation]. Figure 13 The fixing component 4 includes a winch 44, a lifting rope 45, and a hook 46. The two ends of the lifting rope 45 are connected to the winch 44 and the hook 46. The inner surface of the U-shaped plate 31 is provided with a plurality of spaced lifting rings 316. The hooks 46 correspond one-to-one with the lifting rings 316. The winch 44 is provided with a plurality of hooks, which are connected to the corresponding hooks 46 through the lifting ropes 45.

[0094] In practice, the fixing components are set up in 4 groups, with 4 lifting rings set in pairs on the inner wall of the U-shaped plate 31, and the winch is connected to the lifting rings through the hooks on the lifting rope.

[0095] In some embodiments, see Figure 12 One end face of the U-shaped plate 31 forms a snap-fit ​​protrusion 311, and the other end face forms a snap-fit ​​groove 312. The snap-fit ​​groove 312 and the snap-fit ​​protrusion 311 in the adjacent prefabricated component 3 are inserted into each other. The insertion and engagement of the snap-fit ​​protrusion 311 and the snap-fit ​​groove 312 makes the gap between adjacent U-shaped plates 31 form a curved path, which greatly improves the assembly effect between U-shaped plates 31. The gap between adjacent U-shaped plates 31 has a strong sealing effect, which improves the use effect of the prefabricated water channel.

[0096] In practice, the snap-fit ​​protrusion 311 and the snap-fit ​​groove 312 form a labyrinth sealing structure, changing the gap path between adjacent prefabricated parts 31.

[0097] In some embodiments, a water-stop sealing layer is filled between the snap-fit ​​groove 312 and the corresponding snap-fit ​​protrusion 311. The water-stop sealing layer can further improve the sealing effect between the snap-fit ​​groove 312 and the corresponding snap-fit ​​protrusion 311, ensuring that water will not flow out from the gap between the snap-fit ​​groove 312 and the snap-fit ​​protrusion 311.

[0098] Optionally, asphalt can be used as the waterproof sealing layer.

[0099] Optionally, a rubber sealing layer can be used as the water-stopping sealing layer.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
