Description

Technical Field

[0001] The present invention relates to the technical field of waterproof construction, and in particular to waterproof engineering construction equipment and a construction method for high-speed railway tracks. Background Art

[0002] Ballastless track on high-speed railways refers to a track structure that uses a concrete, asphalt mixture, or other materials as a base instead of a granular gravel roadbed. It is currently the most advanced track technology in the world. Ballastless tracks on high-speed railways typically consist of two parallel tracks, and waterproofing is required between the two ballastless tracks and the high-speed railway viaduct deck.

[0003] The traditional construction method involves applying a layer of waterproof coating to the base layer, then using a hot-melt method to bake the coiled material. This process involves compacting the material while baking. This method relies entirely on manual skill, making it difficult to achieve consistent and stable quality, and ensuring quality is difficult. This cumbersome construction process also requires a specific number of coatings to be applied to the upper and lower edges of each internal corner on the high-speed rail ballastless track. These internal corners often require manual work, significantly slowing down the overall construction process and extending the construction period. Summary of the Invention

The feeding device includes a coating head 105, which is slidably mounted on the feeding rail 103. The compacting device includes a compacting roller assembly, which is slidably mounted on the compacting rail 104. During construction, the vehicle body moves forward, and the coating head 105 sprays coating onto the ground or between the coiled material and the ground, then covers the coiled material with the coating. As the vehicle body moves forward, the compacting roller assembly compacts the coiled material.

[0089] The coating head 105 is provided with a feeding bracket 106, and the feeding bracket 106 is provided with a slider adapted to the feeding slide rail. The coating head 105 is slidably connected to the feeding slide rail 103 through the feeding bracket 106. The frame 101 is provided with a feeding electric push rod 107. The piston rod of the feeding electric push rod 107 is connected to the coating head 105 and drives the coating head 105 to slide up and down along the feeding slide rail 103 to adapt to actual construction requirements. Preferably, the left and right ends of the coating head 105 are respectively hinged to the piston rod ends of the two feeding electric push rods, and the two feeding electric push rods 107 can adjust the left and right ends of the coating head to the upper left, lower left, upper right, and lower right respectively to adapt to the height requirements of the high-speed railway track surface.

[0090] The coating head includes a housing 151, which is provided with a feed port 110 and a discharge slit 112. The discharge slit 112 is located at the bottom of the housing 151 and extends along the length of the housing 151. An electric heating tube 114 is disposed within the housing 151. In the present invention, the paint enters through the feed port 110, is heated by the electric heating tube 114, and is extruded from the discharge slit 112. The paint is sprayed evenly and stably.

The discharge seam is slender and uniform, and the coating spraying effect is good.

[0096] The lining 152 is formed by two inner half shells mating together, and a second sealing groove is correspondingly provided on the mating surface of the inner half shells. A second sealing strip is provided in the second sealing groove. The second sealing groove is distributed around the mating surfaces of the two inner half shells and around the paint flow channel 109 to prevent the paint from leaking from places other than the discharge port and the feed port.

[0097] A feed seat is provided at the feed port 110 of the shell 151, and a threaded pipe connected to the waterproof paint pump is provided on the feed seat. The paint needs to be connected to the threaded pipe through the waterproof paint pump, and the paint is pumped into the coating head 105, and then heated and sprayed.

[0098] Sealing rings are respectively provided at the feed port 110 between the feed seat and the outer shell 151 and between the outer shell 151 and the liner 152 to improve the sealing performance of the device and prevent paint leakage.

[0103] In the present invention, two overlapping edge compaction roller sets are preferably arranged symmetrically at both ends of the intermediate compaction roller set. In the present invention, the intermediate compaction roller set and the overlapping edge compaction roller set are arranged in parallel and can move independently of each other to adapt to uneven road surfaces or differences in the overlapping height of the coiled material, thereby improving the coiled material compaction effect.

[0104] The compacting roller group is provided with a compacting bracket, and the compacting bracket is provided with a slider adapted to the compacting slide rail 104. The compacting roller group is slidingly connected to the compacting slide rail 104 through the compacting bracket. A compacting electric push rod is provided on the frame 101, and the compacting bracket is provided with a shock absorber. The compacting electric push rod drives the compacting roller group to slide up and down along the compacting slide rail 104 through the shock absorber.

[0105] The compaction support includes a first compaction support 116 and a second compaction support 117. The first compaction support 116 is provided with a first shock absorber 120, and the second compaction support 117 is provided with a second shock absorber 121. The compaction electric push rod includes a first compaction electric push rod 118 and a second compaction electric push rod 119. The first compaction electric push rod 118 pushes the middle compaction roller group to slide up and down along the compaction slide rail 104 through the first shock absorber 120, and the second compaction electric push rod 119 pushes the overlapping edge compaction roller group to slide up and down along the compaction slide rail 104 through the second shock absorber 121. In the present invention, the compaction roller group is arranged in sections, and the compaction electric push rod and the shock absorber cooperate to make the compaction roller group move up and down according to the height of the construction road surface or the overlapping edge of the coiled material, thereby improving the compaction effect of the coiled material.

[0106] The lower end of the first shock absorber 120 is connected to the first compaction bracket 116 through the support rod 122, and the upper end of the first shock absorber 120 is connected to the piston rod end of the first compaction electric push rod 118; the lower end of the second shock absorber 121 is connected to the second compaction bracket 117 through the support rod 122, and the upper end of the second shock absorber 108 is connected to the piston rod end of the second compaction electric push rod 119.

[0107] The upper ends of the first and second shock absorbers 120, 121 at the same end of the compaction roller group are connected via a pressure rod 123. The piston rod ends of the first and second compaction electric push rods 118, 119 are connected to the pressure rod 123. In other words, the electric push rods at the same end of the compaction roller group can drive the corresponding compaction roller group separately, or they can simultaneously drive the compaction roller group up and down through the pressure rod 110.

[0108] When the piston rod of the compacting electric push rod moves upward, the shock absorber is not under pressure and is at its natural length. At this time, the shock absorber plays the role of a pull rod, lifting the middle compacting roller group and the overlapping side compacting roller group together with the piston rod of the compacting electric push rod; when the piston rod of the compacting electric push rod moves downward, when the compacting roller does not touch the ground, the shock absorber still plays the role of a pull rod, lowering the middle compacting roller group and the overlapping side compacting roller group together with the piston rod of the compacting electric push rod; after the compacting roller touches the ground, the shock absorber begins to be under pressure, and at this time the piston rod of the compacting electric push rod continues to descend, and the shock absorber continues to be compressed, so that the middle compacting roller group and the overlapping side compacting roller group can move up and down independently with the terrain, thereby adapting to the height difference of the overlapping edge of the coil and the uneven road surface.

[0109] The intermediate compacting roller group includes a long compacting roller 124 and two or more first short compacting rollers 125. In this embodiment, two first short compacting rollers 124 are preferably provided. The two first short compacting rollers 125 are provided at both ends of the long compacting roller 124. The first compacting bracket 116 is provided between the long compacting roller 124 and the first short compacting roller 125. The long compacting roller 124 and the first short compacting roller 125 are provided on the first compacting bracket 116 via a bearing shaft 126.

[0110] The middle compacting roller group has only one long compacting roller, and compacting supports are provided at both ends of the long compacting roller.

[0111] The intermediate compacting roller group consists of a long compacting roller and a first short compacting roller, and the compacting bracket is arranged between the long compacting roller and the first short compacting roller.

[0112] The overlapping edge compacting roller group includes two second short compacting rollers 127 , and the two second short compacting rollers 127 are arranged on both sides of the second compacting bracket 117 through bearing shafts 126 .

[0113] The compacting roller group of the present invention adopts a segmented side-shaft-free design (bearing shaft), which can achieve construction close to the wall corner and improve work efficiency.

[0114] The structure of the compacting roller group in the present invention is not limited to the above-mentioned segmentation and combination methods, as long as the compacting rollers can be segmented and move independently of each other and adapt to the height of the road surface.

[0115] The frame 101 is provided with a coil rack 102. A guide roller 128 and an adjusting roller 129 are provided at the rear of the coil rack 102. Both ends of the adjusting roller 129 are connected to the coil rack 102 via springs 130. The adjusting roller 129 can be manually tightened or released to adjust the tension of the coil. After the coil passes through the adjusting roller 129 to adjust its tension, it then passes around the guide roller 128, passes between the feeding device and the compacting device, and is laid on the ground.

[0116] The coil material placement rack 102 includes two relatively arranged coil material supports 137, which can be trapezoidal, rectangular or other structures, and can be equipped with a coil material threading rod 138. The two coil material supports 137 are symmetrically provided with unwinding mechanisms for mounting the coil material threading rod 138. The unwinding mechanism includes two unwinding bearings 139 arranged in parallel. The coil material threading rod 138 is rollingly mounted between the two unwinding bearings 139, and the coil material threading rod 138 can be rolled on the unwinding bearings 139 to rewind or release the coil material.

[0117] The unwinding mechanism can be arranged above or inside the coil support 137. The present invention is preferably arranged inside the coil support so that the coil rod 138 can fall directly onto the unwinding mechanism when rolling along the coil support 137, saving the staff's physical strength and reducing labor intensity.

[0118] The coil support 137 is a tubular structure with a hollow interior. The unwinding bearing 139 is rotatably arranged in the coil support 137 through a bearing rod 140. A placement opening for the coil rod 138 is opened at a position corresponding to the two unwinding bearings 139 on the coil support 137.

[0119] The two ends of the bearing rod 140 are provided with baffles 141, and the two baffles 141 are located outside the two side walls of the coil support 137. After the bolt passes through the baffles 141 and the bearing rod 140, the bearing rod 140 is fixed to the coil support 137 through a nut, which can prevent the bearing rod 140 from shaking on the coil support 137 and ensure the stable operation of the entire device.

[0120] The bearing rod 140 is provided with two bearing rings 142 symmetrically arranged on both sides of the unwinding bearing 139 and located between the two baffles 141 , abutting against the two baffles 141 , thereby ensuring that the position of the unwinding bearing 139 is stable and does not shake.

[0121] A guiding mechanism is correspondingly provided on the inner side walls opposite to each other of the two coil supports 137. The guiding mechanism is located on one side of the unwinding mechanism. The distance between the two guiding mechanisms gradually decreases as the coil approaches the unwinding mechanism. When the coil approaches the unwinding mechanism from the outside, the distance between the two guiding mechanisms gradually decreases, so that the coil can be guided to be roughly centered when it is placed.

[0122] The guide mechanism is a wedge plate 143, which can be a steel plate with a wedge angle. The wider end of the wedge plate 143 is close to the unwinding mechanism, that is, the wedge plate 143 gradually widens from the outside to the inside, and the distance between the two wedge plates 143 gradually decreases.

[0123] Positioning mechanisms for limiting the left and right swing of the coil are correspondingly provided on the opposite inner walls of the two coil supports 37. The positioning mechanisms are located on the other side of the unwinding mechanism. The distance between the two positioning mechanisms is slightly larger than the width of the coil, so that the coil can be accurately positioned on the unwinding device.

[0124] The positioning mechanism includes a fixing frame 145 arranged on the inner wall of the coil support 137. A positioning bearing 144 is provided on the fixing frame 145. During the coil unwinding process, the positioning bearing 144 can roll in contact with the coil retaining ring 146 to reduce the unwinding resistance.

[0125] Coil retaining rings 146 are provided at both ends of the coiled material through-rod 138 to fix, clamp and position the coiled material.

[0126] Threaded sleeves 147 are provided at both ends of the coiled material threading rod 138, and a matching knurled nut 148 is provided on the coiled material retaining ring 146. The coiled material retaining ring 146 is threadedly connected to the coiled material threading rod 138, and the thread facilitates quick disassembly and installation; the knurled nut 148 is used to increase the friction with the hand, making it easy to rotate manually.

[0127] A retaining ring step is further provided on the inner side of the threaded sleeve 147 , and the coil retaining ring 146 stops when the thread rotates to the retaining ring step, thereby limiting the position of the coil retaining ring 146 .

[0128] When the present invention is used, the coil is passed through the coil threading rod, and the coil is placed on the coil support from the side where the guide mechanism is provided and slowly moved inward. The guide mechanism guides the coil so that it is roughly centered when it is placed in. As the coil continues to be placed in, the coil threading rod gradually leaves the constraint of the guide mechanism, and the coil threading rod gradually contacts the positioning device until it completely falls into the unwinding mechanism, thereby achieving the purpose of precise positioning, and the coil can be accurately pulled and unwound on the unwinding mechanism.

[0129] The left and right walls of the vehicle frame 101 are provided with guide wheels 131 that abut against the side walls of the track plate. The guide wheels 131 are provided so that the vehicle body can closely adhere to the side walls of the ballastless track plate and move along the high-speed railway ballastless track.

[0130] It also includes a four-wheel drive system, which is arranged below the frame 101 and is used to drive the vehicle body to move; the four-wheel drive system includes four groups of drive mechanisms arranged below the frame 101, and the drive mechanisms include a motor 132, a reducer 133 and wheels 134. The output end of the motor 132 is transmission-connected to the input end of the reducer 133, and the output end of the reducer 133 is connected to the wheels 134.

[0131] The four-wheel drive system of this invention consists of four independently controlled wheel hubs, each bolted directly to the vehicle body, facilitating assembly, disassembly, inspection, and maintenance. Each wheel hub is driven by a stepper motor and a reducer, and the wheel is connected to the hub shaft via an electromagnetic clutch. When the brushes are energized, the electromagnetic clutch engages, driving the wheel to move. When the brushes are de-energized, the electromagnetic clutch disengages, disconnecting the wheel and allowing manual propulsion of the vehicle. The four stepper motors independently control the four wheels, driving the vehicle for movement, steering, and U-turns.

[0132] It also includes an electronic control system, which is arranged on the frame 101 and is used to control the construction of the vehicle body. The electronic control system includes an electronic control box 135 and a control console 136 that are electrically connected to the frame 101. The electronic control box is installed in the middle of the frame and controls all electrical components through cable connections, that is, the electronic control box 135 controls the connection motor 132, the feeding electric push rod 107, the compacting electric push rod, the electric heating tube 114 and the temperature control probe 110, etc.; the control console 136 is located at the rear end of the frame, and is provided with a touch screen, buttons, a temperature controller and a power switch, etc.

[0133] The four corners of the frame 101 are also provided with lifting rings for lifting the frame.

[0134] The present invention is mainly aimed at the design of ballastless track for high-speed railway bridges. The ballastless track for high-speed railway bridges is generally composed of two tracks. The working surface of the coating and rolling machine is between the two tracks and the high-speed railway bridge, and the track plate is installed on the track plate base. The distance between the two track plate bases is 2.1 meters, and the height of the track plate base is generally 0.2 meters. In conjunction with the new 1.1-meter waterproof membrane specially designed for high-speed railways, two new 1.1-meter waterproof membranes specially designed for high-speed railways are overlapped and laid on the 2.1-meter-wide working surface, with an overlap width of 0.1 meters. Among them, during construction, the guide wheel on one side of the railway track plate special waterproof coating and membrane composite construction machine first clings to the corner of the railway track plate base on one side to lay the first new 1.1-meter waterproof membrane specially designed for high-speed railways; the guide wheel on the other side then clings to the corner of the railway track plate base on the other side to lay the second new 1.1-meter waterproof membrane specially designed for high-speed railways. See the attached. Figure 20-25 The frame 212 of the spray composite paving vehicle is provided with a coiled material through shaft 213 and a handrail 214, a pressure roller 215 is provided at the front of the bottom of the frame 212, and a wheel 216 is provided at the rear of the bottom of the frame 212. A spraying device 217 is provided in front of the pressure roller (215), and a limiting shaft 218 parallel to the coiled material through shaft (213) is also provided on the frame 212.

[0135] The control method of the coating and rolling machine of the present invention comprises the following steps:

[0136] Prepare well, connect the power supply, ensure the ground wire is well connected, the non-curing sprayer pipe and the coating and roll-coating machine feed port are correctly connected, the temperature is set correctly, and the non-curing sprayer and transfer vehicle are correctly connected.

[0137] S1. Click the power button on the device to turn on the power of the whole device;

[0138] S2. Press the start button on the remote control to activate the remote control;

[0139] S3. Long press the button on the pressure roller on the remote control to raise the compaction roller to the top.

[0140] S4. Install the coil on the installation position of the machine body, pass the coil along the specified path, pass the coil around the compacting roller, and lay it on the ground;

[0141] S5. Press and hold the roller down button on the remote control, and the compaction roller moves downward to the bottom.

[0142] S6. Press and hold the start button on the remote control for 2 seconds to start the machine at the set base speed. At the same time, start the non-curing sprayer and adjust the speed knob. The pipe spraying state provides paint to the material silo of the machine body. At this time, the machine moves forward at the base speed. At the same time, the non-curing paint is sprayed onto the ground, and the coiled material is laid onto the waterproof surface by the compaction roller.

[0143] S7. Click the power off button on the machine to turn off the power of the whole machine, unplug the aviation plug power input terminal, tidy up the cables, pipes and machine body, and this construction is completed. Wait for the next construction arrangement.

[0144] After the construction is stopped, the vehicle will be parked at a suitable location as needed, and the remaining rolls will be laid manually. Generally, before stopping the construction, the paint port will stop spraying the paint first to prevent the paint spraying range on the ground from exceeding the length of the roll laying. The compaction roller will press on the paint and be covered with paint, making it inconvenient to clean the compaction roller.

[0145] Click the stop button on the remote control to stop the whole machine. At the same time, the non-curing sprayer should also be stopped. The non-curing sprayer and the coating and roll-coating machine run synchronously.

[0146] The remote control has two control modes: manual mode and automatic mode. Press the start button on the remote control once to activate the remote control, and the remote control is in manual mode; press and hold the start button on the remote control for 2 seconds to put the remote control in automatic mode.

[0147] In manual mode, long press the front and rear buttons on the remote control to move the machine forward and backward respectively, and release to stop. In automatic mode, the front and rear buttons on the remote control are disabled to prevent accidental operation.

[0148] In manual mode, press and hold the left or right button on the remote control to make the aircraft turn left or right. Press and hold the left or right button on the remote control and click the plus or minus button to accelerate or decelerate at the set acceleration or deceleration value when turning left or right.

[0149] During the movement, if you need to move the car to the left, click the left button of the remote control. At this time, the left wheel will slow down, the speed of the right wheel will remain unchanged, and the body will move to the left. If you need to return to the center and move in a straight line, click the right button of the remote control. At this time, the right wheel will slow down, and the speed of the left wheel will remain unchanged. At this time, the speeds of the left and right wheels are equal, and the body moves in a straight line.

[0150] During the movement, if you need to move the car to the right, click the right button on the remote control. At this time, the right wheel will slow down, the left wheel speed will remain unchanged, and the body will move to the right. If you need to return to the center and move in a straight line, click the left button on the remote control. At this time, the left wheel will slow down, and the right wheel speed will remain unchanged. At this time, the speeds of the left and right wheels are equal, and the body moves in a straight line.

[0151] During the movement, if you need to accelerate, press the acceleration button on the remote control once, and the machine will accelerate once at the set speed. Press it twice, and it will accelerate twice at the set speed, and so on. During the movement, if you need to decelerate, press the deceleration button on the remote control once, and the machine will decelerate once at the set speed. Press it twice, and it will decelerate twice at the set speed, and so on.

[0152] Click the feed port up, feed port down, pressure roller up, and pressure roller down buttons on the remote control, and the feed port and pressure roller will move up and down accordingly.

[0153] The machine body is equipped with a touch screen, which can be used to set parameters and operate the machine. The control method of the touch screen is the same as that of the remote control. The parameter settings include the initial speed after the machine is started, acceleration and deceleration values, left and right speeds, etc.

[0154] The touch screen can also be used to fine-tune the discharge port of the silo, for example: upper left, lower left, upper right, lower right.

[0155] The working interface of the touch screen is also provided with an alarm page. During normal operation, if a fault indication occurs, the user enters the alarm page, checks the alarm code, handles the fault in a targeted manner, and then clicks the corresponding clear fault button.

[0156] The pressure roller 215 includes a fixed roller 201 and an adjusting roller 202. The adjusting roller 202 is arranged at both ends of the fixed roller 201. A rotating shaft 203 is provided between the fixed roller 201 and the adjusting roller 202. The rotating shaft 203 is rotatably connected to the shaft sleeve 204, and the shaft sleeve 204 is fixed to the connecting frame 205. A groove 208 is provided on one side of the center of the adjusting roller 202, and a stepped hole is provided on the other side. One end of the rotating shaft 203 is fixedly connected to the fixed roller, and the other end is located in the groove 208. A bolt 206 is provided in the stepped hole. A threaded groove 209 is provided on the rotating shaft 203. The bolt 206 is located in the threaded groove 209 and is threadedly connected to the rotating shaft 203. A spring outside the bolt 206 is located in the groove 208. One end of the spring is fixedly connected to the rotating shaft 203, and the other end is fixed to the bottom of the groove 208. During the movement of the vehicle body, the connecting frame 205 and the shaft sleeve 204 remain stationary relative to the vehicle body, and the rotating shaft 203 rotates in the shaft sleeve 204 under the action of thrust, while the fixed roller 201 and the adjusting roller 202 rotate under the drive of the rotating shaft 203. The fixed roller 201 and the adjusting roller 202 are equivalent to the wheels of the vehicle body rolling forward.

[0157] Spring 207, under its restoring force, pushes against adjusting roller 202, causing the distance between adjusting roller 202 and the fixed roller to change with the axis length, thus adjusting pressure roller 215 in its axial direction. Because the two side portions 406 of the high-speed rail track slab have three grooves of varying widths, waterproofing is performed using a spray-coated composite paving vehicle with adjustable pressure roller length.

[0158] The rotating shaft 203 is connected with the groove 208 by a clearance fit. After the rotating shaft 203 is assembled in the adjusting roller 202, the rotating shaft 203 can be extended and retracted in the groove 208 to achieve the distance adjustment of the pressure roller.

[0159] A bearing 211 is provided between the rotating shaft 203 and the shaft sleeve 204 , and the bearing 211 makes the rotation between the rotating shaft 203 and the shaft sleeve 204 smoother.

[0160] A retaining ring 210 is provided on the outside of the bearing 211. The bolt 206 is a hexagon socket bolt, whose cylindrical head and body respectively match the stepped diameter of the stepped hole. The hexagon socket makes it easy to use tools to rotate the bolt.

[0161] The head of bolt 206 is restricted in displacement by the stepped hole, allowing it to rotate within the stepped hole. When bolt 206 is rotated, it does not move horizontally relative to the adjusting roller. The threads allow shaft 203 to extend in and out of groove 208, while the spring's restoring force keeps adjusting roller 202 pressed to its outermost position. Spring 207 prevents the adjusting roller from sliding freely between the shaft and bolt.

[0162] The limiting shaft 218 includes an adjusting shaft 219 and a fixed shaft 220. The adjusting shaft is disposed at both ends of the fixed shaft 219. A screw 221 and a fixing bracket 222 are disposed between the adjusting shaft 219 and the fixed shaft 220. One end of the screw 221 passes through the fixed shaft 220 and is coaxially welded to the fixed shaft, while the other end passes through the adjusting shaft 219 and is threadedly connected to the adjusting shaft 219. The fixing bracket 222 is sleeved on the screw 221, and a bearing 223 is also disposed between the fixing bracket 222 and the screw 221. The bearing 223 ensures smooth rotation of the fixing bracket 222 relative to the limiting shaft 218. A retaining spring 225 is disposed on the outer side of the bearing 223.

[0163] The limiting shaft 218 is located at the front end of the coiled material through shaft 213, and the height of the limiting shaft 218 is less than the height of the coiled material through shaft 213. The coiled material through shaft 213 is fixed to the frame 212 through a column 224. A groove is provided on the top of the column, and the coiled material through shaft 213 is located in the groove.

[0164] The fixing frame 222 is rotatably connected to the limiting shaft 218 , and the coil slides on the surface of the limiting shaft 218 . The rotatable limiting shaft 218 reduces the friction of the coil during sliding.

[0165] The adjusting shaft 219 is rotated. Under the action of the threaded assembly, the adjusting shaft 219 rotates back and forth on the screw rod 221, thereby changing the length of the limiting shaft 218 to be suitable for coils of different specifications and models.

[0166] The end of the screw rod 221 is provided with a screw 226, which is used to fix the position of the adjusting shaft 219 relative to the screw rod 221 after the adjusting shaft 219 is rotated and changed. When the limit shaft 218 is rotated, the adjusting shaft 219 is prevented from moving back and forth, affecting the construction.

[0167] A limiting ring 227 is provided on the outside of the adjusting shaft 219. The outer diameter of the limiting ring 227 is larger than the outer diameter of the adjusting shaft 219. The limiting ring 227 is used to limit the coil during the rotation of the limiting shaft 218 to prevent the coil from escaping from the limiting shaft 218.

[0168] The spraying device 217 includes a spraying bracket 228 and a spraying pipe 229. The spraying bracket 228 has a spraying pipe 229 at one end and is fixed to a U-shaped pipe 232 at the other end. The U-shaped pipe 232 is fixed to the fixing frame 222. The spraying pipe 229 is provided with a nozzle 226 and a paint inlet 231. Two nozzles 226 are provided, located at both ends of the spraying pipe.

[0169] A heating pipe is provided inside the spray pipe 229. A cylindrical barrel is provided at the center of the spray pipe 229. The cylindrical barrel forms a ring structure with the paint bin of the spray pipe 229. One end of the cylindrical barrel is fixed to the spray pipe 229, and the other end is open and connected to the outside. The heating pipe is located inside the cylindrical barrel. The heating pipe is connected to a temperature control device to heat and control the temperature of the paint. Baffles 233 are provided on both sides of the spray pipe 229. The baffles 233 are fixed on the U-shaped tube 232 and are located at both ends of the U-shaped tube 232. The baffles 233 limit the spraying of the sprayed paint to prevent the paint from splashing everywhere. Two nozzles 226 are provided, evenly distributed on the spray pipe 224.

[0170] Paint inlet 231 is connected to the sprayer via a pipe, which feeds the coating tube. U-shaped tube 232 is fixed to mounting bracket 222. The width of U-shaped tube 222 is greater than the maximum width of limiting shaft 218. While U-shaped tube 222 securely connects spraying device 217 to limiting shaft 218, it also creates a space between them for the coiled material to pass through. After being redirected by limiting shaft 218, the coiled material passes through the central space of the U-shaped tube, where it is sprayed with paint by the sprayer and spread on the ground.

[0171] See attached Figures 26-29The frame 301 of the spray edge banding vehicle 3 is provided with a limit box 303 in front, which is equipped with a spray window 306. The paint in the spray pipe 302 passes through the spray window 306 and is then applied to the internal corner. The spray window 306 defines the position, shape, and direction of the paint spray. The size of the spray window 306 matches the required waterproofing dimensions of the internal corner. After the waterproofing paint is sprayed out of the spray pipe 302 and passes through the spray window 306, it is restricted by the spray window 306 and sprayed into the specified shape, thus waterproofing the internal corner.

[0172] The spray window 306 is composed of two mutually perpendicular through holes, one of which is perpendicular to the horizontal plane. When the vehicle is moving, the through hole at the horizontal end is close to the bottom surface, and the through hole at the vertical end is close to the wall. The spray window 306 fits the inner corner, and the shape of the spray window 306 is the shape of the inner corner waterproof edge sealing. Waterproof coating is sprayed through the spray window 306 for waterproof edge sealing. The height and width of the spray window 306 are the height and width of the sealed inner corner. When the vehicle is moving, a long row of inner corners can be waterproofed by spraying. The height a of the spray window 306 is 5-10 cm, and the width b of the spray window 306 is 5-10 cm.

[0173] The spray pipe 302 includes an adapter 307 and a nozzle 309. One end of the adapter 301 is connected to the feed pipe of the sprayer through a thread. The other end of the adapter 307 is provided with an elbow 310, and the elbow 310 is connected to the nozzle 309. An adjustable angle joint 308 is added between the elbow 310 and the nozzle 309. The spray pipe 302 is provided with a heating rod and a temperature control device.

[0174] When the paint is sprayed out, it flows through the sprayer, the feed pipe, the adapter 307, the elbow 310, the adjustable angle joint

[0175] 308, nozzle 309. The adapter 307 is fixed to the vehicle body via a bracket and serves as an intermediate piece to connect the sprayer to the elbow 310. After one end of the elbow 310 is connected to the adapter 307, the other end faces the spray window, limiting the spray direction. The elbow is connected to the nozzle 309 via an adjustable angle joint 308, which adjusts the direction of the nozzle 309. The adjustable angle joint 8 is a ZSPJ15 type universal joint.

[0176] The top of the bracket features two interlocking fixed shells, which encase the adapter 307 and secure it in place. The fixed shells are provided with a cylindrical hole 311, housing a heater rod connected to a temperature control device enclosed by a protective cover. The connectors are all made of metal, a good conductor of heat. Heat from the heater rod is transferred through the metal components, heating the paint within the adapter 307. When the heater rod reaches a certain temperature, the temperature control device deactivates the heater rod, thereby regulating the paint's discharge temperature. The heater rod heats the adapter, and the heat source is very close to the nozzle, minimizing heat loss.

[0177] The side walls of the vehicle 301 are provided with two to three horizontal guide wheels 305. During vehicle movement, the guide wheels 305 closely follow the wall and control the direction of travel. If one or more guide wheels 305 are not in close contact with the wall, it indicates that the vehicle 301 is skewed and requires prompt adjustment. The vehicle 301 is provided with a handrail 304 and four casters at the bottom for easy propulsion.

[0178] The waterproof engineering construction method of the present invention comprises the following steps:

[0179] a. Base surface treatment: including base surface flatness treatment, drainage hole treatment, base surface moisture content treatment, and base surface cleanliness treatment;

[0180] b. Install the drainage pipe on the base layer and bond the reinforcement layer around the drainage pipe;

[0181] c. Waterproof layer structure: Waterproof membranes are laid on the base surface of the middle part and both sides of the track base.

[0182] While laying the coiled material, spray the waterproof coating between the coiled material and the base surface, and vent the coiled material during the spraying and laying process;

[0183] d. Internal corner waterproof layer construction: spray waterproof coating on the internal corner of the waterproof layer;

[0184] e. Protective layer construction: pouring concrete protective layer on the surface of waterproof layer;

[0185] f. Construction of secondary inner corner waterproof layer, spraying waterproof coating on the inner corner of the protective layer.

[0186] During the base leveling treatment in step a, the specific manifestation of local convexity of the base surface is the presence of steel bar heads, stones, debris, foreign objects, etc. on the base surface. Exposed steel bar heads should be cut, stones, debris and foreign objects should be knocked off, and small areas should be polished with an angle grinder, while large areas should be polished with an electric grinder. The manifestation of local depression of the base surface is the presence of local low-lying areas on the base surface, which should be repaired and leveled with polymer-modified cement mortar after roughening and cleaning. When the base surface is not dense, it may manifest as the presence of honeycombs, rough surfaces, peeling, looseness, and floating slurry on the base surface. Honeycombs and rough surfaces should be filled and locally repaired with polymer-modified cement mortar; floating slurry should be polished, and peeling and loose areas should be knocked off to expose a solid base surface of the concrete bridge deck.

[0187] In the treatment of the base drainage holes in step a, an angle grinder is used to grind the periphery of the drainage holes, with the outer grinding range being 35cm*35cm. At the same time, the floating slurry inside the drainage holes is removed, and then cement mortar is used to repair the periphery of the holes.

[0188] During the moisture content treatment of the base layer in step a, the surface moisture content of the damp base surface should be ≤10%. Random testing should be conducted on-site using a surface moisture meter. If the base surface has been submerged in water for a long time or has accumulated water, causing it to be saturated with water, it should be air-dried or dried using drying equipment.

[0189] In the base cleanliness treatment of step a, use a broom to sweep away powder, residue and debris on the base surface, then clean it with an industrial vacuum cleaner or blower, or rinse it with a high-pressure water gun and then blow it dry. There should be no obvious dust on the base surface when touched by hand.

[0190] In the installation of the drainage pipe in step b, the reinforcement layer should be bonded around the drainage pipe and flanged before the waterproof layer is laid. The reinforcement layer should be made of non-woven fabric or mesh impregnated with hot-adhesive modified asphalt coating.

[0191] During the waterproofing layer construction in step c, the ambient temperature should be above -20°C. Outdoor work should not be conducted on rainy, snowy days, or in wind speeds above level 4. Construction should not be conducted if there is accumulated water, snow, or ice on the base surface. The beams should not be contaminated during waterproofing.

[0192] The sprayed waterproof coating is hot-adhesive modified asphalt.

[0193] The waterproof membrane should be laid from low to high in the direction of the water flow, and the rolling and exhausting should be done during the laying process. The weight of the rolling steel roller should not be less than 15kg and the diameter should be 15cm.

[0194] Hot-adhesive modified asphalt waterproofing membrane should be laid to the base of the ballast wall, protective wall, base plate and water retaining platform. After rolling the edge of the membrane, there should be natural overflow of asphalt coating and the edge should be smoothed and sealed with a scraper. Hot-melt rubber asphalt coating should be used for reliable bonding at the longitudinal and transverse overlaps of the membrane. There should be natural overflow of asphalt coating at the overlap seams, and the overlap width should not be less than 10cm.

[0195] In step e, the protective layer should be poured after 0.5-1 hour after the waterproof layer is constructed. The waterproof layer should not be subjected to vehicle or heavy object rolling before the protective layer is constructed.

[0196] In steps c, d, and f, the viscous modified asphalt waterproof coating should be discharged until the asphalt is nearly flowing and glossy black. Application should be done by scraping or spraying. During spraying, the heating temperature for the viscous modified asphalt waterproof coating should be between 175°C and 190°C, and the discharge temperature should be between 170°C and 180°C.

[0197] When spraying, first heat the paint to the desired temperature, then start the dedicated spray equipment and check that the spray gun and nozzle are operating properly. Start the spray gun for a test spray. Once the spray gun is operating normally, proceed to spraying over a large area. When spraying over a large area, adjust the distance between the nozzle and the base surface and the spray pressure. Apply half the paint to the bottom of the waterproofing membrane and half to the concrete base. Ensure a uniform coating thickness of at least 1.5 mm. Each spraying surface should be 20 mm wider than the membrane to ensure full adhesion. The overlap width of the same coating layer should be 20 to 30 mm.

[0198] When spreading the waterproofing membrane, the membrane should be laid straight, flat and without wrinkles, with an overlap width of a, a≥100mm, and the height of the hot-adhesive modified asphalt waterproofing coating overflowing from the edge of the joint should be no less than 10mm.

[0199] See attached Figure 30-32 The waterproof system after construction consists of a waterproof membrane layer 401, a waterproof coating layer, and a protective layer 403. The protective layer 403 is located above the waterproof membrane layer 401. A first coating edge sealing layer 402 is located at the edge between the waterproof membrane layer 401 and the protective layer 403. A second coating edge sealing layer 404 is located at the upper edge of the protective layer 403. The first coating edge sealing layer 402 is 150 mm wide and 30 mm high, while the second coating edge sealing layer 404 is 80 mm wide and 80 mm high.
