However, the patent does not provide a technical solution or idea for transforming saline-alkali grassland into fertile farmland and doubling precipitation in arid areas. Contents of the invention

[0003] One of the objects of the present invention is to provide a method for constructing a water management area.

[0004] The method of constructing a water management area of ​​the present invention is as follows: a target area is demarcated in a natural area, and water-proof materials are laid on at least part of the land in the target area to form a water-proof layer to transform it into a water-proof area, and the water-proof area includes water-proof farmland; the remaining untransformed land in the target area is the original area; the combination of the water-proof area and the original area is called the water management area. The water management area includes cities, villages, fields, wilderness, highlands, surface waters and deserts; the area and proportion of the water-proof area in the water management area are not limited, including an area greater than or equal to 10,000 m 2 , especially greater than or equal to 5km 2and accounts for more than 50%; the waterproof material divides the land into the cultivated layer above and the foundation below. The waterproof material blocks the water from moving between the cultivated layer and the foundation, so that most of the rainwater in the waterproof farmland re-enters the atmosphere through transpiration; the thickness of the cultivated layer is not limited, including the range of 0.1 to 2 meters; preferably in the range of 0.5 to 1 meter. Water-proof materials include but are not limited to agricultural mulch, geotextiles and waterproof mud and sand bag paving layers; there is no limit to the laying method of water-proof materials, including continuous laying and fragmented laying; continuous laying includes connected laying and non-connected laying; connected laying refers to the connection between the laid water-proof materials, including but not limited to bonding, heat welding, ultrasonic welding, seaming and nailing with nails; non-connected laying includes simply overlapping or approaching the edges of two paving materials; fragmented laying does not interfere with specific objects on the site, including trees, rocks and structures; on the basis of the above-mentioned laying of water-proof materials to construct a water-proof area, it also includes superimposing one of the following three points and their combination: 1) leveling and cleaning the cultivated layer of the water-proof farmland to remove stones, and cleaning to remove salt and alkali and other harmful substances, including but not limited to arsenic-containing substances; 2) equipping the water management area with a rain enhancement system, taking advantage of the characteristics of low rainwater leakage and low temperature in the early morning of the continental climate, which is easy to increase rainfall, to continuously increase rainfall through rain enhancement. For relevant content, please refer to existing technologies; 3) Supporting water conservancy facilities in the water management area include the construction of reservoirs and artificial rivers, and the rational use of groundwater and surface water.

[0005] Beneficial Effects: The method of constructing a water management area provides a technical means for transforming saline-alkali land and dry land into high-yield arable land, and provides a water management area, a water-insulated farmland, and a sustainable means of rainwater enhancement and water extraction. Define a model plot: area 5 to 100 km 2 The arid and semi-arid land, continental climate, and early morning temperatures during the planting season that are often below the dew point are suitable for rain enhancement. External influences on the model plot include wind and increased water vapor. The vast majority of rainwater in the water-removed farmland re-enters the atmosphere through evaporation, laying the foundation for sustainable rain enhancement to increase crop yields and the use of water conservancy facilities to extract water from the air to supply daily life and production. Sustainable rain enhancement involves implementing rain enhancement in the early morning hours, increasing rainfall during the planting season from 120 mm to over 1,400 mm. At the beginning of the planting season, a small amount of groundwater is extracted for irrigation in the water-removed farmland, and sustainable rain enhancement is initiated to amplify precipitation; when necessary, recharge is used to balance the groundwater level. The adverse effects of wind on rain enhancement are minimized by designing a rain enhancement plan that optimizes the entire water vapor transmission pathway. The water-removed farmland is desalinated by flooding the fields and draining water.

[0019] Implementation Method

[0020] Figure 1 shows Example 1. An excavation-type compost turning and laying system is manufactured, comprising an excavator 1, a laying machine 2, and a control system. The excavator comprises two mechanical arms 3 and two buckets 4. The laying machine comprises a housing 5. The housing adopts a modular design, with a full-length output port 6 oriented in the same direction as its centerline, several closers 7 evenly spaced along the inner side of the output port, and a roller conveyor array 8 at the bottom of the housing. The width of a single housing ranges from 2 to 6 meters. The working surface width can be increased, including up to 60 meters, by connecting the flange end faces 9 at both ends of the housing. The bottom edge 10 of the housing, viewed from the front, may be a straight or curved waveform. The amplitude of the waveform is not limited, including 0 to 900 mm, and the length of the waveform is not limited. The bottom edge of the housing in Figure 1.5 is a V-shaped triangular waveform, and its waveform length is equal to the width of the housing. The waveform of the laying machine bottom determines the cross-sectional shape of the waterproof material. The control system includes a leveling detector installed on each laying machine to provide real-time leveling information to the control system host. For relevant information, please refer to the prior art. At least one set of drive wheels 11 is evenly distributed across the bottom of the housing. A shovel plate 12 is positioned in front of the drive wheels. The shovel plate scrapes away the soil in front of the paving machine, improving the dimensional accuracy of the foundation surface. In one possible design, the drive wheels of Example 1 are replaced with spiral drive wheels. For more information, refer to existing sled technology.

[0021] The roller conveyor array consists of several rollers, each connected to the base via a rotating sub-mechanism, including an electric roller 13 with a drive motor. These electric rollers propel the stacks of water-blocking material 14 atop them forward. The water-blocking material is stacked and placed on the roller conveyor array, where it is subsequently pulled out layer by layer from top to bottom during installation. This is the default placement and delivery method for the water-blocking material. One side of the water-blocking material is reinforced with a side 15, facilitating insertion and insertion of the material through the gap between the upper and lower rollers of the closer during installation. A housing contains one or more closers, mounted inside the outlet port. These closers comprise one or more airbags 16, a spring 17, a transmission element, an upper roller 18, and a lower roller 19. A gap of 1 to 100 mm is permitted between adjacent closers. The airbags are connected to a positive pressure source, a negative pressure source, or the atmosphere via control valves. The transmission element consists of a top plate 20 and a pushpin-like transmission rod 21, which is connected to the top plate. The upper and lower surfaces of the top plate contact an airbag and the upper end of a spring, respectively. The drive rod is connected to the upper roller via a one-dimensional rotational pair. The closer has two stable states: open and closed. When the closer is open, the airbag is connected to a negative pressure source or the atmosphere, causing internal pressure to be lost. The spring extends, pulling the drive rod upward (as shown in the solid line in Figure 1.4), widening the gap between the upper and lower rollers and facilitating the passage of waterproof material. When the closer is closed, the airbag is connected to a positive pressure source, expanding, compressing the spring, and moving the upper roller downward (as shown in the dashed line in Figure 1.4). This narrows the gap between the upper and lower rollers, preventing the ingress of mud. The lower roller is connected to the housing via a one-dimensional rotational pair. The upper and lower rollers may or may not have a drive mechanism. Both rollers have sealing strips to the housing's output port to prevent dust and mud. An auger head 22 is located at each end of the front of the paving machine. The auger head consists of a drive shaft 23 and a spiral blade 24 located in front of the drive shaft. The auger bit has the functions of both a drill bit and a spiral propulsion, providing partial or full forward driving force for the paving system and crushing the soil, making the working state of the paving system more stable. The horizontal inclination angle of the auger bit can swing slightly, and the swing includes using a servo or connecting the free end of a hydraulic device on the side of the drive shaft through a one-dimensional rotation pair mechanism to achieve, which is used to change the horizontal inclination angle of the paving system during advancement, and to achieve control of the operating depth of the paving system and the degree of undulation along the forward direction. Considering the shell width of 5 meters, the drive shaft diameter of 25mm, and the range of 50mm on both sides of the drive shaft where the bucket is not allowed to intrude, the operating range of the bucket is slightly reduced. The use of a auger bit to pre-crush the soil improves excavation efficiency. The design of the auger bit refers to the existing technology.

[0022] Example 1: Working process: Each excavator is in place, digging a transverse trench to the foundation. The laying machine is unloaded from the vehicle, including lifting and unloading with the excavator. Each laying machine housing is widened by connecting the flange end faces on both sides to form an excavator laying system and then placed into the transverse trench. A 40-90 degree arc-shaped additional channel 25 is installed on the left side of the housing. The closer is switched to the open position. A whole stack of waterproofing material is hoisted into the housing through the upper port of the additional channel and into each housing through the side port. The electric rollers of the roller conveyor array are activated, including manually passing the reinforced edge of the waterproofing material through the gap between the upper and lower rollers and the output port, and synchronously advancing to the end. The additional channel is then removed and the closing side panels or amplifying splicers are installed. The waterproofing material is then pulled back to a sufficient amount. The closer is switched to the closed position. The pulled waterproofing material is pressed with soil. The excavator is then activated to dig soil and cover the newly laid waterproofing material to form a tillage layer 26. The waterproofing material divides the land into a foundation 27 below the waterproofing material and a tillage layer above the waterproofing material. The longitudinal waveforms of the water-blocking material formed by excavation include those shown in the upper curve of Figure 1.1. In Example 1, two buckets are used, with one bucket providing support for the other bucket as it extends forward to unload material, as shown in Figure 1.1. Similarly, using the left bucket to unload material to the right front, as shown in the right excavator in Figure 1.2, the right bucket provides support, improving the excavator's operating conditions. Using two buckets can significantly reduce the weight of the excavator.

[0023] Beneficial effects of Example 1: The excavation-type paving system of the present invention provides a special device for constructing water-proof areas. The excavator has high reliability after aging; the use of dual mechanical arms and dual buckets allows for rapid progress. Excavation also has a deep plowing effect. The parallelogram shell has a compact structure, making full use of the slope of the soil behind and being friendly to bucket operations. With a paving operation width of 60 meters and an average paving speed of 0.1 meters per second, 21,600 meters of paving can be achieved per hour. 2 Total area is 2.16 hectares.

[0024] In one possible design, Example 1 uses an electric excavator instead of an internal combustion engine-driven excavator. In one possible design, the additional channel in Example 1 is equipped with a roller conveyor array to facilitate the loading of waterproofing materials. In one possible design, the excavator arm of Example 1 includes a laser alignment signal receiver 28 for receiving laser alignment signals emitted by an external base station in real time to position the laying system, including making the longitudinal cross-section of the waterproofing material appear as the waveform shown in the upper part of Figure 1.1. The non-linear waveform of the longitudinal cross-section of the waterproofing material superimposed on the non-linear waveform of the cross-section allows the waterproofing material to be evenly distributed with pits for easy water storage, which helps to maintain good soil moisture, improve the drought resistance of waterproof farmland, and make the waterproofing material less sensitive to damage. In one possible design, the forward speed of the roller conveyor array in Example 1 is gradually increased from front to back. This can produce axial compression of the entire stack of waterproofing materials, including shortening it from 68 meters to 66 meters, making the laid waterproofing materials loose. The spiral drill bit in Example 1 can be omitted; its spiral drive wheel can also be replaced with other wheel sets.

[0025] Figure 2 illustrates Example 2. The edges 29 of two adjacent waterproofing materials 14 laid down two times overlap, achieving a non-connected joint. The gap between the two edges is located higher than the rest of the waterproofing material. The overlap, including the projected area of ​​the two edges, is shown in Figure 2. This non-connected joint still effectively reduces leakage, but omitting the connection operation helps reduce renovation costs. The joint is higher than the rest of the waterproofing material, allowing the cultivated layer to retain more water and improve moisture retention. The gap at the joint allows excessive rainwater to seep into the ground, mitigating waterlogging and replenishing groundwater.

[0026] In a possible design, the projected areas of the edges of the two adjacent water-blocking materials in Example 2 do not overlap. If the projected areas of the edges of the two adjacent water-blocking materials in the drainage area do not overlap, for example, the average area is 60*500m 2 The waterproof material has a 0.1-meter splicing gap between one 60-meter side and one 500-meter side and the adjacent waterproof material. The area of ​​this gap accounts for less than 0.19% of the water management area, and the leakage increase it brings can be ignored in terms of rainfall enhancement and salt and alkali return.

[0027] Figure 3 shows Example 3. A water-insulating area 30 is constructed in a water-scarce area, including an urban area 31 and surrounding suburban farmland. Water-insulating materials are laid underground in the suburban farmland to form water-insulating farmland, and each aerial rain-increasing operation area is designed as shown in the dotted line diagram. The area, shape, position and height of the rain-increasing operation area vary according to the on-site conditions, including changes in wind speed and direction. Beneficial effects of Example 3: The construction of a water-insulating area and the superposition of rain-increasing technology can increase rainfall in the water-insulated farmland and improve soil moisture conditions. It can also bring rainwater to urban roads, buildings and green spaces, making the air fresh, and can also obtain water for living and production through the rainwater collection system.

[0028] FIG4 shows Example 4. A milling-type turning and paving system is manufactured, comprising a paving machine 2, an array of milling screw conveyors, a rear soil conveyor 32, a forward horizontally mounted spiral drill head 22, a spiral drive wheel 11 at the bottom of the paving machine, and a control system. The paving system is dragged forward by a cable 33. The control system includes a horizontal state detector provided on each paving machine. The screw conveyor is a general bulk material conveying equipment, comprising a spiral blade and a conveying trough; when the spiral blade rotates, the material is pushed to move in the conveying trough. The milling screw conveyor array includes a number of milling screw conveyors 34 evenly distributed on the entire working surface. The milling screw conveyor includes a spiral conveying milling cutter and a conveying trough. The spiral conveying milling cutter is obtained by arranging dense cutting edges on the edge of the spiral blade, which has both milling function and spiral blade pushing function; the rear soil conveyor includes but is not limited to the use of a screw conveyor or a conveyor belt.

[0029] Working process of Example 4: Each tractor is pulled into position, digging a transverse trench to the foundation 27, unloading the milling screw conveyor array and the paving machine to enter the transverse trench, including the paving machine shells being widened in parallel, and multiple milling screw conveyor arrays being evenly distributed on each paving machine to form the paving system; loading the water-proof material and then pulling the water-proof material out from the paving machine output port and pressing it with soil. Then, the tractor pulls the paving system through the cable, milling and lifting the soil while moving forward. The soil is transported to the water-proof material 14 laid at the rear through the rear soil conveyor to build the tillage layer 26. Beneficial effects of Example 4: The milling-type composting paving system uses a milling screw conveyor array to mill the soil, which has a compact structure, high reliability, and the turned soil is evenly dispersed.

[0030] Figures 5 and 6 illustrate Example 5. A mud pump turning and laying system is constructed for constructing water-insulated paddy fields 35. The system includes a beater array, a mud pump 36, a mud pipe array, an underwater laying machine 2 comprising an elbow laying machine 37, a blower 38, a first manipulator 39, a second manipulator 40, a height rudder, and a control system. The control system includes a monitor 42 and level detectors installed on each laying machine. An artificial river 43 and dam 44 connect to the field ridge 45 and also serve as a mechanized farming road. A splicing trench 46 is dug on both sides of the field to prevent soil 47 from rolling off. A box dam 48 is placed end-to-end in the splicing trench and filled with water to increase weight, forming a temporary dam for supporting water-insulating materials. Each box dam is connected by cables for pulling. The box dam's body 49 is enclosed and equipped with a mounting interface, anti-sticking steel plates, and a material clamp. The connection interface includes several recessed through-holes to facilitate connection of specialized equipment and water injection. Inside the box, a pumping pipe 50, a segmented main pipe 51, a power supply, and a box dam control system are installed. The lower end of the pumping pipe leads to the bottom of the box dam, and the upper end is connected to the segmented main pipe within the box dam. An external water pump can pump water out of each box dam through the segmented main pipes and the pumping pipe. The box dam control system includes a wireless communication module for intercommunication. The material clamp includes a pressure plate 52 connected to the box via a one-dimensional rotational pair and connected to the electric mechanism. The pressure plate has three stable operating states: 1) outward-turned state, 2) inward-closed state without pressure, and 3) inward-closed state with pressure. In the outward-turned and inward-closed states, the pressure plate has no effect on the outside world; in the inward-closed state with pressure, the pressure plate compresses the waterproof material below it. The beater array includes several beaters 53 and a rear fairing 54, which serves as the input port for the mud pump. The beater combines the functions of milling and beating the soil; the beaten soil can be easily pumped. The beater includes a self-injecting water-filled end mill, which includes a spindle and a water-injected cutting edge. The water-injected cutting edge features a porous water-injected surface structure. The porous water-injected surface structure includes several output holes connected to a water source through waterways of equal length and resistance. For relevant details, please refer to the prior art. The mud pipe array includes several mud pipes 55 and one or more groups of two propellers 56, each group including a screw propeller. Each mud pipe is relatively centralized at its outlet by a cable. Each group of two propellers is located on either side of the mud pipe outlet and is connected to the mud pipe to drive the mud pipe outlet to maintain the appropriate position. The elbow laying machine includes a machine housing, an output port, and internal components machined and arranged in a 40- to 90-degree arc. A fan 38 and a rubber pusher 57 are provided at the first end of the laying machine. The rubber pusher is used to adjust the water-blocking material on the box dam. At the second end, a rubber push handle and an electric heating turntable 58 or glue applicator are provided. The height rudder is connected to the laying machine using a rudder bar 59 to control the working state of the laying system, including turning upward or downward.The beater array, mud pump, mud pipe array, laying machine and elbow laying machine, horizontal status detector, monitor, fan, first manipulator, second manipulator, elevation rudder, and propeller are connected to the control system host signal via their own interface circuits; their status changes according to the changes in the host state. The laying process of Example 5: Each traction device, including a hauling or hoisting machine, is in place, the laying machine is placed in the transverse trench, the laying machine is widened in parallel and connected to two elbow laying machines, the waterproof material 14 is installed, and the beater array, mud pump, mud pipe array, fan, two manipulators, and elevation rudder are installed to form a mud pump laying system. Pull out the waterproof material from the output port and place both sides of it on the box dams on both sides, which are the first layer of waterproof material on the box dam in Figure 6.1 and the second layer of waterproof material on the box dam in Figure 6.3 respectively. Then, start the fan to blow the waterproof material output near the top onto the box dam, start the first and second manipulators to adjust the waterproof material, press it and achieve heat welding; then press the remaining waterproof material with soil. Then, pull the laying system by cable 33 to lay the waterproof material. The monitor monitors the site. During laying, the beater array includes milling and beating the soil by swinging back and forth for dozens of degrees. The mud output from the mud pipe forms a mud highland, and the low-lying area 61 between the highland and the temporary dam retains the water separated from the mud. After the laying is completed, the water in each box is pumped out through the segmented main pipe and the pumping pipe, the water level of the on-site splicing ditch is controlled to float the box dam, and the space between the welded waterproof material and the splicing ditch is blown to make it swell as shown by the dotted arch in Figure 6.3, and the box dam is continuously pulled out and removed. Finally, the water and air in the splicing ditch are pumped out, and the waterproof material is submerged in the splicing ditch in an orderly manner. The laying is completed. Example 5 Beneficial Effect: The mud pump paving system of the present invention uses a beater array to mill the soil for slurry and a mud pump to pump the soil, and has the advantages of compact structure, high reliability, light equipment weight, low cost and low energy consumption.

[0031] In one possible design, the box dam in Example 5 is replaced with a ridge to separate strips of land. In one possible design, Example 5 uses multiple sets of propellers to carry and transport the mud pipes. In one possible design, the mud pipes in Example 5 deliver mud to adjacent plots. In one possible design, Example 5 uses a rigid mud pipe output array and omits the propellers.

[0032] FIG7 shows Example 6. A tractor underground paving system is manufactured, comprising a tractor 62, a paving machine 2, a connecting rod assembly 63, a moldboard 64, and a paving control system. The connecting rod assembly connects the tractor and the paving machine; the working state of the connecting rod assembly is controlled by a hydraulic device 65, including cutting the paving machine into the ground and pulling the paving machine out and lifting it. The paving machine is controlled to flip up or down by a hydraulic device 66. The paving machine has a streamlined cross-section and includes a housing 5, a full-length output port, a closer, and a roller transmission array. The moldboard is optional and is mounted on the connecting rod assembly with a horizontal tilt angle to chop and lift the soil in the tillage layer 26 and increase the sinking force of the paving machine. The horizontal tilt angle T ranges from -5 to -30 degrees. The working process of Example 6: Each tractor is in place, each paving machine is unloaded and connected to the connecting rod assembly of the corresponding tractor and lifted. Each housing is connected and widened by its flange end faces on both sides to form a tractor paving system. Then load the waterproof material; pull the waterproof material back far enough and press the waterproof material with soil; adjust the hydraulic device of each tractor to make the shell cut into the ground and drag the shell forward to lay the waterproof material.

[0033] Beneficial Effects of Example 6: The traction-type underground paving system of the present invention provides specialized equipment for laying water-blocking materials to construct drainage areas. This system eliminates the need for extensive soil turning, minimally altering the soil structure of the original cultivated layer, and conserves energy. In one possible design, a moldboard angle screw adjustment device 67 is employed between the moldboard and the connecting rod assembly of Example 6. This device comprises a paired screw and nut, one end of which is connected to the connecting rod assembly and the moldboard via a rotating joint. The moldboard is also connected to the connecting rod assembly via a rotating joint. This adjustable moldboard angle ensures that the system is always operating at its optimal state.

[0034] FIG8 shows Example 7. A traction-type underground laying system is constructed, comprising a tractor 62 and an underground laying machine 2 towed by a cable 34 of a winch 68 on the tractor. The laying machine comprises a housing, a cable connection interface mast 69, and a control system. The working process of Example 7 is as follows: the tractor is in position and a transverse trench 70 is dug; the laying machine 2 enters the transverse trench; the laser receiving device on the laying machine receives the laser beam emitted by the base station for measurement and positioning. For relevant content, reference can be made to the prior art. The housings of multiple laying machines working in parallel are connected in series to increase the working width, a whole stack of waterproofing material is loaded, waterproofing material 14 is pulled out from the output port of the housing onto the foundation, and soil is covered on the pulled waterproofing material to press it down. The winch on the tractor and the mast of the laying machine are connected by a cable 33. The tractor is started to pull the laying machine to lay the waterproofing material. The soil passing over the laying machine 2 falls on the laying material behind the laying machine to form a tillage layer 26. Beneficial Effects: The traction-type underground paving system of the present invention provides a technical means for laying water-proof materials to construct water-proof areas or water-proof farmland. The use of a winch for traction can achieve more complex and precise traction control and a faster paving speed.

[0035] Figure 8 illustrates Example 8. Based on Example 7, a front-row tractor 71 is added, employing two rows of tractors, which relay-tow the paving machine 2. Definitions: 1) Switching point 1 is defined as the moment when the front-row tractor is far from the paving machine, the rear-row tractor is close to it, and the front-row tractor begins relay traction. The distance and proximity include, but are not limited to, 30 meters and 8 meters, respectively. Definition 2) Switching point 2 is defined as the moment when the rear-row tractor is close to the front-row tractor and the rear-row tractor begins relay traction. The proximity includes, but is not limited to, 4 meters. Example 8 operation process: At Switching point 1, the front-row tractor stops and tows the paving machine, while the rear-row tractor advances until Switching point 2. The rear-row tractor stops and tows the paving machine, while the front-row tractor advances to Switching point 1. This cycle continues. Advantages of Example 8: When the tractor is stationary, the static friction between it and the ground is significantly greater than the kinetic friction when it is in motion. Therefore, a lighter and smaller tractor can be used to achieve the same traction force, which helps reduce equipment cost. The winch traction control has high precision. Using a model with front and rear tractors, the tractors can independently complete different tasks, including cleaning and leveling, for nearly half of the time. For scenarios where related operations must be performed, twice the result with half the effort. In one possible design, the generator equipped with the tractor of Example 8 supplies power to the paving machine. The paving machine has an additional power supply option. In one possible design, the paving system of Example 8 includes a hydraulic top plate 72, which uses the resistance generated by the top plate to increase the traction force on the paving machine behind. In one possible design, all possible embodiments of the present invention are improved: a vibrator is equipped to part of the shell of the paving machine, including a vibration generator used for a concrete vibrator to reduce the resistance and energy of the paving machine.

[0036] FIG8 also illustrates Example 9. Based on Example 7 or 8, a new operating module 73 is added to the tractor, including a detection module for 3D terrain modeling, an earthmoving module for trenching, ridge building, and leveling, and a harvesting and weeding module. The detection module includes an ultrasonic detection device to facilitate 3D modeling; the earthmoving module includes a bucket. For related technologies, reference can be made to existing technologies.

[0037] FIG9 shows Example 10. An underground paving machine is manufactured, comprising a housing 5, quick-release screw conveyor cutters 74 evenly distributed on the front side of the housing, a laser receiving device 28, three rows of screw conveyors (front row 75, middle row 76, and rear row 77) evenly distributed on the upper side of the housing, each row relaying conveyors, a mast 69 connected to the housing, a roller conveyor array 8 within the housing, a synchronous pusher 78 for water-blocking materials, a closer and water-blocking material extension splicer 79, and a widening splicer located outside the housing for splicing adjacent water-blocking materials. The housing is designed and manufactured in a modular manner, utilizing special-shaped flange end plates at both ends to achieve connection and widening. The wedge-shaped front end of the housing includes a lower wedge surface 80 and an upper wedge surface 81. The wedge is suitable for wedging into soil. The lower wedge surface has a horizontal angle 82 ranging from 1 to 7 degrees. The quick-install spiral conveyor milling cutter includes a cutter for milling, chopping and lifting earth, and moving the earth upward to the top of the paving machine housing; while lifting the earth, its reaction force provides a downward thrust to the paving machine; the thrust changes with the change of the rotation speed of the quick-install spiral conveyor milling cutter, so it can help adjust the operating state of the paving machine by changing the quick-install spiral conveyor milling cutter; the functions of each row of spiral propulsion conveyors include providing horizontal propulsion for the paving machine and generating relative displacement between the paving machine and the soil above it; the inclined spiral propulsion conveyor will generate a vertical component force. In Figure 9, the three front-to-back connected spiral propulsion conveyors 74 to 76 are equipped with a conveying trough. Each spiral propulsion conveyor is equipped with a power head 83 to drive independently, or a power head plus one or more universal joints 84 to drive in combination;

[0038] The synchronous pushers are evenly distributed along the inside of the shell. The synchronous pushers include a pushing robot arm 85, a driving roller 87 arranged at the free end of the pushing robot arm, and a monitor. The speed of the driving roller is adjustable, and it acts on the top of each stack of waterproofing materials 14 to help the waterproofing materials to move and output synchronously as a whole, including relying on the built-in monitor to monitor the site. This can avoid the disorder caused by the adhesion of two adjacent layers of waterproofing materials. The pushing robot arm maintains the appropriate pressure of the driving roller on the waterproofing material; the surface linear speed of the driving roller is the same as the laying speed and can be adjusted. The extended splicer is used to connect extended waterproofing materials.

[0039] Working process of Example 10: The tractor drives the laying machine forward and supplies power to the laying machine via a cable; the quick-install auger milling cutter shreds and lifts the soil; the three rows of auger conveyors relay the soil backward to form a tillage layer 26 and provide forward thrust for the laying machine; and the water-blocking material is discharged from the output port. Beneficial effects of Example 10: The laying machine utilizes a mast to connect to the cable 33 on the tractor, giving the tractor more degrees of freedom; the tractor directly pulls the laying machine, eliminating the need for turning the soil and simplifying the process; the three rows of auger conveyors relay the soil backward and provide forward thrust for the laying machine, reducing the cable drive load. In one possible design, Example 10 is modified to include a smaller diameter upper portion of the quick-install auger milling cutter. The smaller diameter reduces driving force. In one possible design, the auger conveyors relaying the soil on the upper side of the housing of Example 19 are designed other than the three rows. In one possible design, a portion of the housing of Example 10 utilizes a porous water-injected surface structure. The porous water-injected surface structure forms a slurry that provides lubrication, helping to reduce the drive energy required for the laying machine. In one possible design, the laying machine of Example 10 includes a moldboard 64 and a moldboard angle screw adjustment device 67. Cable tension combined with the buoyancy of the reduced water-blocking material in the laying machine causes the laying machine to move upward and off its designated track. The moldboard provides a downward reaction force, resolving this issue and allowing the laying machine to operate freely underground.

[0040] Figures 8 and 10 illustrate Example 11. A multifunctional tractor 62 is manufactured, comprising tracks, a chassis, an engine, a bucket, and a transversely mounted screw conveyor 86; its uses include combining a leveling machine and a towing paving machine. The screw conveyor is connected to the tractor via a hydraulic device 65 and can rotate clockwise or counterclockwise. The transverse screw conveyor includes an open conveying trough 88 with a baffle, screw blades 24 disposed within the conveying trough, widening baffles 89 disposed along the edge of the conveying trough, hydraulic bypass covers 90 disposed on the outer side of the conveying trough, hydraulic end valves 91 disposed at both ends of the conveying trough, a power head 82, and a conveyor control system. The power head includes both electric and hydraulic power heads. The screw blades can rotate in both directions. When the bypass cover is opened or closed, material in the screw conveyor can or cannot flow out of the bypass channel 92 of the conveying trough. The bucket 4 can pour soil from above the widening baffle of the transverse screw conveyor into the conveying trough. The hydraulic end valve has two stable states: open and closed. When the hydraulic end valve is in the open state, this end is switched to the output end; when the hydraulic end valve is in the closed state, this end is switched to the input end. Working process of Example 11: Use multiple tractors to level the ground in parallel, and connect the transverse screw conveyors on these tractors end to end in a relay conveying state. When the input end of one of the two adjacent transverse screw conveyors is just below the output end of the other screw conveyor, the two transverse screw conveyors are said to be in a relay conveying state, and materials can be transferred between the two screw conveyors in the relay conveying state. When the two transversely arranged screw conveyors need to change the conveying direction, the tractors carrying the two screw conveyors are staggered front and back, and then the states of the two transverse screw conveyors are adjusted, including switching their input and output ends. Then, the two tractors carrying the two transverse screw conveyors are aligned and enter a new relay conveying state. Advantages of Example 11: When tractors equipped with transversely mounted augers and bucket-type working modules are arranged in rows, they can simultaneously complete tasks such as leveling large plots of land, up to 60 meters wide, and on-site material transport, including the transfer of soil from and to vehicles on ridges. The soil is used for soil improvement. In one possible design, Example 11 employs tractors equipped with transverse augers in both the front and rear rows.

[0041] FIG11 shows Example 12. A device for lengthening waterproof material of a laying machine is manufactured, comprising a panel 93 and a control system, equipped with an upper air blowing pipe row 94, a lower air blowing pipe row 95 and a waterproof material status detector, for thermally welding and lengthening the final section 96 of the waterproof material and the initial section 97 of the newly installed waterproof material. The width of the panel is the same as the width of the shell; the height dimension of the panel along the forward direction, i.e., the length direction, ranges from 90 to 500 mm; the panel is arranged above the output port in the laying machine shell 5. A plurality of electromagnets 98, air holes 99 and electric heat welders 100 are evenly distributed on the panel. The electromagnets include strip electromagnets, and the length direction of the strip electromagnets is the same as the width of the panel. The air holes are connected to the positive pressure source and the negative pressure source through an automatic control valve. When the air holes are connected to the negative pressure source, the front and rear sides of the initial section of the waterproof material near the front of the panel are pressed against the end section in front of the panel due to the pressure difference between the atmospheric pressure and the negative pressure source. When the air holes are connected to the positive pressure source, a blowing force is generated on the end section in front of it. The air hole edges include processed chamfers. The port styles of the air holes include but are not limited to dots and short oblique lines. The oblique short line-shaped air hole ports can suck air from a larger area. Typically, the air holes on the panel are grouped, and each group uses a scanning method to connect to the negative pressure source for suction. This helps to reduce interference. When the electric thermal welder is in operation, the temperature of its working surface increases, which can heat and weld the two layers of waterproof material adjacent to it together. The shape of the surface of the electric thermal welder is the trace pattern generated by the welding, including but not limited to dots, lines, and meshes. The upper and lower air blowing pipe rows are arranged above and below the output port, respectively. The upper and lower air blowing pipe rows are connected to a positive pressure source via an automatic valve, and their air outlet states are adjustable. The lower air blowing pipe row is used to blow the final and initial sections of the waterproof material upwards and close to the panel. In order to fine-tune the position of the final section on the panel, the upper air blowing pipe row is used. The upper air blowing pipe row is connected to the positive pressure source via an automatic valve. For a final section blown by the lower air blowing pipe row, the air blown by the upper air blowing pipe row can blow the final section into a downward-bulging arc section, which acts to pull the final section down from the panel. In other words, the final state of the final section on the panel changes according to the state of the upper air blowing pipe row when it floats upward. This phenomenon is used to adjust the displacement of the final section on the panel. Several small holes 101 are evenly distributed on the final section and contain paramagnetic material. Paramagnetic material itself does not have magnetic attraction ability but can be attracted by magnets, and therefore will not absorb mud and sand. The final segment includes a plastic sheet doped with paramagnetic material powder that is connected to the panel without interfering with heat fusion. The paramagnetic material can be arranged in any manner, including a strip of paramagnetic material 102. The length of the strip of paramagnetic material is aligned with the axis of the housing; the center distance between two adjacent strips of paramagnetic material is equal to the center distance between two adjacent strips of electromagnet surfaces on the panel. This helps reduce the discreteness of the final segment's final magnetic attraction position on the panel and improves the accuracy of the final segment's position on the panel, including ensuring that the strip of paramagnetic material is attracted to the electromagnet surface with an accuracy error of less than or equal to ±3 mm.The small hole is as close as possible to the air hole on the panel when it is sucked by the electromagnet; the diameters of the small hole and the air hole are both 1 to 3 mm; the negative pressure source sucks the initial section through the air hole on the panel and the small hole on the final section so that the initial section is close to the final section.

[0042] Working process of Example 12: When the detector reports that the waterproof material is about to run out and needs to be lengthened, the main machine stops the laying machine, exhausts the air from the upper and lower air pipes, and estimates the possible magnetic attraction state based on the detector report and adjusts the state of the upper and lower air pipes accordingly; then the air holes of the relevant groups are connected to the negative pressure source in sequence, and the electromagnet is switched to the magnetic attraction state; this causes the last section to be magnetically attracted to the panel under the multiple effects of exhausting air from the upper and lower air pipes, negative pressure suction of the air holes, and magnetic attraction of the electromagnet. Maintain the electromagnet's magnetic attraction, turn off the negative pressure source and the upper and lower air pipes. The laying machine inserts 14 waterproof materials into place, as shown by the dotted trapezoid in Figure 11.5. The detector reports that the newly installed waterproof material is in good condition. The main machine sequentially activates the lower air pipe to exhaust air, preheats the electric heat welder, and connects each set of air holes, from bottom to top, to the negative pressure source for negative pressure suction. This causes the initial section of the newly installed waterproof material to be attracted to the front end of the panel by the dual action of the lower air pipe exhaust and the air hole negative pressure suction. The electric heat welder is then turned on to initiate the heat welding operation. After the two layers of waterproof material on the surface of the electric heat welder are heat-fused, the electric heat welder and the negative pressure source are turned off. The air holes are then connected to the positive pressure source in a scanning manner to blow the waterproof material away from the surface of the electric heat welder. Finally, the electromagnet is turned off, and the heat welding extension process is complete. Restart the waterproof material laying operation. The heat-melting seam on the water-insulating material is consistent with the pattern formed by the surface of the electric heat welder. The electric heat welder and its heating surface include but are not limited to point, line segment and mesh shapes.

[0043] In one possible design, the end section contains ultrasonic reflective material, including aluminum foil with a protective layer. In another possible design, the surface of the electric heat welder in Example 12 has a non-planar shape, including a slightly outwardly smooth convexity in the middle, as seen in cross-section; the convexity has a height ranging from 0.3 to 1.4 mm. This can improve the quality of the heat weld. In one possible design, the monitor is mounted on the drive roller 86 shown in Figure 9, and the movement path of the pusher arm 85, which is connected to the drive roller, is confined to a narrow space near the symmetry plane of the shell. This provides a wide field of view and is less likely to be obstructed by the end section. In Example 12, the multi-layer welding mechanism remains effective even when the panel's inclination angle varies. Advantageous Effects of Example 12: The waterproof material extension device for a laying machine of the present invention provides a method for mechanically extending waterproof material, with the advantages of clear physical significance and simple implementation. The use of an upper air pipe row allows the position of the end section on the panel to be adjusted. The greater the air blow from the upper air pipe row, the more the end section bulges downward, and the lower the end section moves on the panel. The use of an electromagnet to magnetically attract the end section avoids the impact on the installation of waterproof materials.

[0044] Figure 12 illustrates Example 13. A manually assisted extended waterproofing material laying machine is constructed, comprising a housing 5, a slide rail 103 arranged along and connected to the housing's output port, an electric scooter 104 associated with the slide rail, and an electric sewing machine 105. The electric scooter is connected to the slide rail via a rolling connection interface 106 and can freely move forward and backward on the rail. The working process of Example 13: When the monitor within the laying machine indicates that the waterproofing material is about to run out, the laying machine's laying system enters earthwork avoidance mode, directing the excavator, rearward screw conveyor, or mud pump pipe to move the soil 47 away from the laying machine, ensuring that the laying machine's output port 6 is not buried by the soil. A worker lies on the electric scooter to pull out the waterproofing material end 96, cutting off some of it if it is too long. New waterproofing material is then loaded, and the reinforcing edge 15 is manually advanced to the end. The end section and the reinforcing edge are then manually sewn together by the electric sewing machine. Laying can then continue. The beneficial effect of Example 13: Construction of water-insulating farmland can begin several months earlier, eliminating the need to wait for the development of an extended splicer. With minimal equipment changes, construction of water-insulating farmland can begin several months earlier. Figure 13 illustrates Example 14. A device for horizontally widening and splicing water-insulating material is manufactured, comprising a housing 107, a space within the housing for storing the welded portion of the water-insulating material, a stretching and cleaning assembly, a roller connection assembly, and a control system. The device is mounted on the exterior of a laying machine 2 and is used to splice newly laid water-insulating material with previously laid water-insulating material. The stretching and cleaning assembly includes one or more sets of two spiral roller brushes 108, each set consisting of two upper and lower spiral roller brushes working in conjunction with each other, and a vacuum cleaner 109 mounted on one side of the spiral roller brushes. The upper and lower spiral roller brushes are positioned on either side of the water-insulating material 14, each with spirally arranged bristles. As the water-insulating material passes between the rotating upper and lower spiral roller brushes, it is scraped and pulled along the direction of rotation by the spiral roller brushes, and stretched and widened along the axial direction of the spiral roller brushes. This scraping action cleans the surface of the water-insulating material. The vacuum cleaner includes a suction nozzle, which approaches and cleans the spiral roller brush. The roller connection assembly includes a set of two electric hot-melt welding rollers 110 that work together; the two layers of water-insulating material passing between the two electric hot-melt welding rollers are welded. The working principle of Example 14: Each time a row of water-insulating material is added to the side of the already laid water-insulating material, it includes clearing the site on one side of the laying machine, loading the water-insulating material into the laying machine, installing the transverse widening and splicing device, and then manually loading the already laid water-insulating material into the stretching and cleaning assembly and the roller connection assembly; then loading the side of the current water-insulating material into the roller connection assembly, and finally closing the cover. Then, the electric hot-melt welding assembly is activated and the laying machine is started to lay the water-insulating material. As the laying machine moves forward, the cover of the widening and splicing device lifts the soil in front, and the stretching and cleaning assembly in the cover pulls up the edge of the previously laid water-insulating material and cleans it, and welds it with the edge of the currently laid water-insulating material.Beneficial effects of Example 14: The device for lateral widening and splicing of waterproof materials of the present invention can use a spiral roller brush to complete the picking up, cleaning, stretching and widening of the waterproof material laid previously and the heat-melting of two layers of waterproof materials at one time during movement. The use of two or more sets of spiral roller brushes can increase the cleaning margin. In one possible design, the heat-melting in Example 14 is changed to ultrasonic welding, bonding or sewing. In one possible design, Example 14 is changed to non-connected stacking splicing, including using only one set of spiral roller brushes to pull outward and clean the edges of the waterproof material laid this time.

[0045] Figure 14 shows Example 15. A waterproof material axial compression platform is manufactured, comprising a plurality of electric rollers 13, the center line of which is perpendicular to the drawing, and at least one end of the electric rollers at both ends can be rotated upward as a whole at a large inclination angle. The working process of Example 15: After the roll / stack of waterproof material 15 is placed on the axial compression platform, at least one of the electric rollers at both ends is rotated upward as a whole at a large inclination angle and there is a transition arc segment with the middle part, so that the electric rollers are rotated to push the waterproof material to the middle, and the waterproof material is compressed along its axial direction and its length is shortened. Beneficial effects of Example 15: The waterproof material axial compression platform can perform axial compression on waterproof materials in stacks with a length of more than 60 meters, and the compression effect is intuitive and controllable. The roll / stack of waterproof material that has undergone axial compression has a tendency to recover its original length, and is adaptable to various subsequent lateral elongation situations, including not being easily damaged when pulled due to an uneven base surface. In one possible design, axial compression of the stack of waterproofing materials is achieved when loading them into the laying machine. This involves giving the electric rollers of the roller conveyor array in Figure 1.5 a linear speed gradient along the conveying direction, with the speed decreasing as the stack moves forward, thus compressing the entire stack of waterproofing materials. This approach is simpler and has better practical effects.

[0046] FIG15 illustrates Example 16. A self-propelled dry paving machine 2 is manufactured, comprising a paving machine and front and rear propellers 111 mounted approximately horizontally on a paving machine housing 5. The propellers are capable of swinging up and down, left and right, and are driven by a two-dimensional servo and two-dimensional hydraulic device to advance and lay water-blocking material 14. The paving machine comprises a modular housing, which is connected by flanges at both ends to increase the width of the working surface; the housing is provided with an output port arranged along its centerline; a roller conveyor array is provided at the bottom of the housing; and water-blocking material is stacked on the roller conveyor array and can be discharged from the output port. Example 16 is used to lay water-blocking material underground, dividing the land into an upper arable layer and a lower foundation. The water-blocking material prevents water from migrating between the arable layer and the foundation, allowing most rainwater in the water-blocked farmland to re-enter the atmosphere through evaporation. In one possible design, a tractor is used to assist in towing the paving machine 2 via a cable 33 and a mast 69. Beneficial effects of Example 16: The self-propelled dry paving machine of the present invention is propelled by a front-row screw propeller and a rear-row screw propeller, has a simple structure, and is suitable for laying water-insulating materials in the desert.

[0047] FIG16 illustrates Example 17. An artificial river with an aquiclude is constructed in a desert. An excavator 1 is used to excavate the desert to a sufficient depth. The excavated earth is screened and separated into rocks 113, pebbles 114, and soil 47 using a screening device 112. This earth is then transported to dams 44 on both sides of the artificial river 43 using a screw conveyor 87. The remaining rocks, pebbles, and soil are then filled upwards in descending order of volume to form a riverbed foundation 27. Waterproof material 14 is then laid on the riverbed foundation, including the slopes 115 on both sides, to form an aquiclude. Earth bags 116 are then stacked on top of the earth bag. The earth bags are made of geotextile and filled with soil. The earth bag and the earth bag form an aquiclude. The aquiclude separates the desert into a riverbed above the aquiclude and a foundation below it, preventing water from flowing between the riverbed and foundation. Sediment remains on the riverbed and on the earth bag. The bottom sludge is included as part of the river self-cleaning system. The content of the screening device refers to the existing technology.

[0048] In a possible design, the river channel slope is arranged in a stepped shape 117, so that the stacked earth bags are more neat and stable. In a possible design, Example 17 sets a water main 118 at the bottom of the artificial river 43, including a device for conveying saline waste water. In a possible design, the water-blocking material of the artificial river of Example 17 adopts an aerial laying machine 2 reinforced with a grid structure 119, and the laying machine relies on the vehicles above the dam 44 and the engineering machinery in the artificial river under construction to load and move forward. In a possible design, the water-blocking material in Example 17 is laid at a small horizontal inclination angle below the slope as shown by the double dotted line in Figure 16.3. This method of moving the water-blocking material downward and leveling it avoids the problem that large-angle water-blocking materials may cause landslides. In a possible design, land is reclaimed from the sea, and terraces are built at the dam ridge as shown by the thick dotted line in Figure 16.3.

[0049] Figure 17 illustrates Example 18. A screening screw conveyor is manufactured, comprising a screw blade 24, a conveying trough 87, a screen 120, and a power head. The screw blade comprises a screw conveying milling cutter; the screw blades are available in both shafted and shaftless versions, with the latter being less prone to clogging. The conveying trough accommodates one or more screw blades and comprises a rear plate 121 and side plates 122. The screen comprises various steel screens, some of which are integrally formed with the conveying trough. The power head comprises a reduction motor and a hydraulic motor. The operating process of Example 18: Whether in a desert, dry land, or swamp, the screw conveyor mills / beats and lifts soil as it travels. As the soil passes through the screen, the vast majority of it is screened through the mesh. A small amount of oversize material is sent to a designated location for disposal. The screen comprises a gradient screen, i.e., a screen with mesh openings that monotonically increase in size along the direction of the soil's movement. The screened soil is distributed via a dedicated channel 123. The dedicated channel comprises a classification container or a chute leading to the classification container, and the material conveyor comprises a screw conveyor. Advantageous Effects of Example 18: The sieve of Example 18 is connected to a vibration source to improve the separation efficiency.

[0050] FIG18 illustrates Example 19. An excavator 1 equipped with an integrated vibrating screen bucket is manufactured, comprising a crawler chassis, a mechanical arm, and an integrated vibrating screen bucket. The integrated vibrating screen bucket comprises a bucket 4, one or more vibrating screen meshes 120 disposed within the bucket, a vibration source 124, an oversize bypass channel 92, and a cover plate 90. The vibration source comprises a vibrating device such as a concrete vibrator. The operating process of Example 19 is as follows: After each excavation, the integrated vibrating screen bucket is moved to the oversize placement position. The bottom cover is opened to accumulate the screened soil as a tillage layer 26. The oversize material 125 from each layer of the integrated vibrating screen bucket is then transferred to another location and poured into the excavated pit, with the smaller the particle size, the higher the position. The oversize material is then laid in layers to form a foundation 27, as shown in FIG18.4. Each layer is leveled and compacted, as shown in FIG18.2. Simultaneously with the laying of the oversize material and each layer of oversize material, a laying machine is used to lay one or more layers of water-blocking material 14. Beneficial Effects: The vibrating screen-integrated bucket provides a technical means for transforming deserts into fertile farmland. It takes only seconds longer than conventional buckets to separate and lay out various types of desert components, including simultaneous separation during digging, transfer, unloading, and laying. In one possible design, Example 19 includes two paving machines 2, a bulldozer 126, and a movable sorting platform. The two paving machines 2 are connected to the bulldozer via a drive shaft 23 and can be driven by the bulldozer. The paving machines' front shovel molds 12 push the soil in front of them. A laser receiver 28 is configured to receive collimation signals from a base station for spatial positioning. The movable sorting platform includes a crawler chassis, a bulldozer bucket and a self-unloading vibrating screen 127. The self-unloading vibrating screen includes one or more layers of screen 121, a vibration source, a sieve storage space, a sieve bypass channel 92 and a cover plate. The self-unloading vibrating screen is connected to the crawler chassis through one or more hydraulic adjustment devices, and its horizontal inclination angle can be adjusted for inclined materials. The movable sorting platform is used to further subdivide the sieve transferred by the bucket into fine soil and screen material. The screen material is first dumped between the front and rear rows of paving machines. Then the cover plate is opened to dump the fine soil onto the upper layer of water-proof material as a tillage layer. Its beneficial effects include providing layered paving of sand and gravel to form a new foundation and its leveling and compaction, and providing filling between two layers of water-proof material by separation. In a possible design, the vibrating screen-integrated bucket and self-unloading vibrating screen of Example 19 and its improved version are both equipped with strain gauges and force sensors. To record the weight of various components of the material each time. In one possible design, both the front and rear rows of the paving machines in Example 19 and its improved versions are equipped with strain gauges and force sensors to provide real-time information on the density of the underlying foundation during paving. In another possible design, Example 19 uses a sand maker to make sand from the sorted stones and use it as a new foundation. In another possible design, Example 19 uses planting pots for planting, addressing the problem of insufficient arable soil.

[0051] Figure 19 shows Example 20. A system for turning and laying inflatable tubes is manufactured, including a drive device, a laying machine, and an elbow laying machine 37. The drive device includes a tractor or winch and a cable. At the first end, a water trough excavator 128, a plate manipulator, an auxiliary water-blocking material spool 129 and / or a plastic film tube spool 130, an electric heating turntable or glue applicator, and a water level control assembly are provided. The water trough excavator is connected to the laying machine via a drive shaft 23 and excavates a water trough 131. The cross-section of the water trough comprises an isosceles quadrilateral with a depth and long sides of several centimeters. The auxiliary water-blocking material spool and the plastic film tube spool respectively hold the auxiliary water-blocking material and the plastic film tube. The water pipe cleaner includes a vacuum nozzle template 132. The surface shapes of the upper and lower suction interfaces of the vacuum nozzle template match the surfaces of the water-blocking material and inflatable tube 133, respectively. For relevant details, reference can be made to the prior art. The electric heating turntable 58 is used for heat welding of the water-isolating material and the inflation tube. The glue applicator is used to apply the adhesive material between the water-isolating material and the inflation tube, which includes a glue injection interface and a pressure roller 134. The water level control assembly ensures that water is stored inside the inflation tube before the water-isolating material is laid to prevent it from being blown away by the wind, and is responsible for sucking the inflation tube deflated after the water-isolating material is laid. At the second end, a water pipe cleaner, a second electric heating turntable or a second glue applicator is provided; the water pipe cleaner includes an overlapping area suction nozzle template. The working process of Example 20 includes a first end and a second end: at the first end, the water-isolating material with the inflation tube is laid: the laying system is driven to move forward, while digging a water sump and laying the water-isolating material with the inflation tube. The laying of the waterproof material with the inflation tube includes one of the following four methods or a combination thereof: 1) heat-melting a piece of auxiliary waterproof material 135 on the lower side of the edge of the waterproof material, including producing two heat-melting seams on both sides of the auxiliary waterproof material and forming an inflation tube; the inflation tube is placed in a water sink when laying the waterproof material; 2) heat-melting a piece of auxiliary waterproof material on the lower side of the edge of the waterproof material, including producing two heat-melting seams on both sides of the auxiliary waterproof material and placing a plastic film tube 136 in the inflation tube, 1) Form a double-layer inflation tube, including an inner plastic film tube and an outer tube formed by heat-fusing a waterproofing material and an auxiliary waterproofing material; the double-layer inflation tube is placed in a water sump when laying the waterproofing material; 2) Connect a plastic film tube at the edge of the waterproofing material, including heat-fusing or gluing; the plastic film tube is placed in a water sump when laying the waterproofing material; 3) Place or connect a inflation tube on the edge of the waterproofing material, including heat-fusing or splicing; the inflation tube is placed in a water sump when laying. When covering easily laid waterproofing material with soil, it is required to keep the area several tens of centimeters from the edge of the water sump, where adjacent waterproofing materials overlap, as free of soil as possible. Fill the inflation tube with water to increase its weight and prevent it from being blown around by the wind.At the second end, the inflatable tube is covered with waterproof material to complete the splicing of the two layers of waterproof material. This is shown in Figure 19.1. Depending on the situation, the following procedures may be used: First, clean the surface of the inflatable tube with a pipe cleaner, including using a vacuum nozzle template to dry the surface of the tube, as indicated by the two rows of arrows in Figure 19.1. Then, glue is applied to the joints between the two layers of waterproof material and pressed together using a pressure roller, or an electric rotary welding machine is used to weld the two layers of waterproof material. To prevent the inflatable tube from slipping, a pressure roller is used to restrain the inflatable tube. Soil is then covered over the two layers of waterproof material, and the tube is deflated after installation. Clearly, this splicing process can meet stringent waterproofing requirements. Even if a small amount of moisture remains in the inflatable tube, it still acts as a seal, preventing water from flowing between the base 27 below the waterproof material 14 and the cultivated layer 26 above. The double-dashed circle in Figure 19.2 indicates that the plastic film water pipe reel box has been moved to the front of the laying machine, allowing the inflatable tube to be placed on the waterproof material. The width of the water-blocking material should be such that the resulting inflatable tube has a diameter of several centimeters. The diameter of the inflatable tube should be such that it stretches straight and does not roll in the water settling tank. Advantageous Effects of Example 20: Multiple splicing options for two adjacent pieces of water-blocking material are possible, requiring only excavation of the water settling tank, soil turning without disturbing the tank, and minimal equipment changes.

[0052] Figure 20 illustrates Example 21. A paving system utilizing a water trough to retain mud and water for overlapping joints is constructed, comprising a drive device and a paving machine 2. A water trough excavator and a protective plate manipulator 137 are located at the first end; an overlapping area suction nozzle template 138 is located at the second end. The drive device comprises a tractor or winch and a cable. The water trough excavator is connected to the paving machine via a drive shaft to excavate a water trough 131. The cross-section of the water trough is an isosceles quadrilateral with a depth and long sides of several centimeters. The protective plate manipulator comprises a steel plate approximately one meter long and 0.5 to 0.8 meters wide, and a large plastering knife, used to compact and smooth the piled soil 47 on the edge of the water trough to maintain its shape. The outer shape of the bottom of the suction nozzle template in the overlapping area matches the shape of the ground at the water sump, and contains suction holes, which are connected to a negative pressure source; it is used to lift the waterproof material laid below when laying the waterproof material above the splicing part, and scrape the waterproof material below at an angle of 30 to 60 degrees with its plane normal relative to the forward direction to remove the mud on the waterproof material. The working process of Example 21 is divided into two parts: the first end and the second end; the first end includes digging out the water sump, placing the waterproof material into the water sump and pressing the waterproof material with water and / or mud to prevent wind; the second end includes cleaning the upper surface of the first layer of waterproof material at the overlap and covering it with part of the second layer of waterproof material 14 to achieve overlapping splicing. Beneficial effect of Example 21: At the cost of turning over the mud without interfering with the water sump, adding slope protection boards and suction nozzle templates in the overlapping area, overlapping splicing with a width of more than 0.5 meters is achieved.
