Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled material processing, and in particular to a water-leakage-proof pre-laid waterproof coiled material and processing equipment thereof. Background Art

[0002] Waterproof membrane is a flexible building material product that can be rolled into a roll. Due to its excellent waterproof performance, it is often used in building walls, roofs, tunnels, roads, landfills and other places. It can resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] Waterproofing membrane processing equipment is a kind of equipment specially used for manufacturing, processing and producing various types of waterproofing membranes. These equipments play a key role in the waterproofing industry, and are used to process different materials into rolled waterproofing materials for application in various places such as building roofs, basements, and floors.

[0004] In the existing anti-leakage pre-laid waterproof membrane processing equipment, in order to ensure that the waterproof membrane can be well connected when it is laid, when processing the waterproof membrane, it is necessary to apply adhesive to the waterproof membrane through the waterproof membrane processing equipment, so as to ensure the waterproof performance and sealing performance of the waterproof membrane. However, in the process of processing and production, only by applying adhesive to the waterproof membrane alone and then bonding them together through the adhesive, the sealing performance between the waterproof membranes cannot be effectively guaranteed, because the adhesion performance between the adhesive and the waterproof membrane will be affected by various factors, such as: the temperature is too high or too low, and the flatness of the surface of the waterproof membrane, which will cause the adhesion performance between the waterproof membrane and the adhesive to be poor and uneven coating, thereby reducing the sealing performance between the waterproof membranes, which is easy to cause the waterproof membrane to leak.

[0005] In view of this, in order to solve the above-mentioned shortcomings, the present invention has developed a water-leakage-proof pre-laid waterproofing membrane and a processing equipment thereof. Summary of the invention

[0006] The technical problem to be solved by the present invention is as follows: In the existing anti-leakage pre-laid waterproof membrane processing equipment, the adhesive is only applied to the waterproof membrane alone, and the adhesion performance between the waterproof membrane and the adhesive is poor and the application is uneven, which leads to reduced sealing performance between the waterproof membranes and easily causes leakage of the waterproof membrane.

[0007] The present invention provides the following technical solutions: a water-leakage-proof pre-laid waterproof coiled material processing equipment, comprising a base, a coiled material drum, a film pressing drum and a winding drum; the base is rotatably mounted with a coiled material drum, the base is rotatably mounted with a film pressing drum, the base is rotatably mounted with a winding drum, and also comprises a plastic connection mechanism, the plastic connection mechanism is fixedly mounted on the base, the plastic connection mechanism rotates and plastically bonds the material to the waterproof coiled material through spiral rotation and extrusion, and is bonded and formed as a whole with the waterproof coiled material.

[0008] When processing the pre-laid waterproof membrane, the waterproof membrane needs to be placed on the membrane drum, and then the waterproof membrane passes through the plastic joint mechanism, the material is heated and melted, and the waterproof membrane is bonded, and small cylindrical protrusions arranged in an array are bonded on both sides of the waterproof membrane, and are shaped and cooled, and then the film cylinder is pressed, and a layer of protective film is covered on both sides of the waterproof membrane to protect the cylindrical protrusions on both sides of the waterproof membrane, and finally reaches the winding drum, and the waterproof membrane is stored and packaged, thereby completing the bonding and forming of the waterproof membrane, so that the waterproof membrane has better sealing performance after bonding and splicing, and prevents leakage at the joints of the waterproof membrane.

[0009] The plastic joining mechanism includes an upper pressing roller, a lower pressing roller, a rotating drum, a limiting roller and a shaping roller; the upper pressing roller is rotatably installed on a base, the lower pressing roller is rotatably installed below the upper pressing roller, the lower pressing roller rotates to evenly extrude the material and shapes and adheres it to the two ends of the coil, a rotating drum is rotatably installed inside the lower pressing roller, the rotating drum transports the material to the two ends of the lower pressing roller through bidirectional spiral rotation; the limiting roller is rotatably installed on one side of the lower pressing roller, and the shaping roller is rotatably installed on one side of the limiting roller.

[0010] In order to ensure that the waterproof membrane can fit with the lower pressure roller, an upper pressure roller and a limiting roller are installed on the top and side of the lower pressure roller respectively, so that the waterproof membrane passes through the upper pressure roller and the lower pressure roller and between the limiting roller and the lower pressure roller respectively, and the internal material is transported and squeezed onto the waterproof membrane through the rotating drum. The material is melted after heating to form a relatively flowing liquid, and the autonomous fluidity is low. It needs to be squeezed and pushed to make the material flow. The material can be polyethylene, or other plastic materials that can adhere to the waterproof membrane. The lower pressure roller is used to extrude small cylindrical protrusions on both sides of the waterproof membrane, and then the waterproof membrane is cooled by the shaping roller, so that the cylindrical protrusion and the waterproof membrane form a whole, so that the subsequent waterproof membrane can fit more tightly during the bonding and splicing process, so as to improve the sealing performance and waterproof performance of the waterproof membrane, and prevent water leakage at the joints of the waterproof membrane.

[0011] The interior of the lower pressure roller is a hollow structure, and a plurality of circular through holes are opened in a circular array with the axis as the center at both ends of the lower pressure roller. Circular holes are opened axially at both ends of the lower pressure roller, and a cylinder is fixedly installed in the circular through hole on the lower pressure roller. The cylinder is rotated by the lower pressure roller, and the radial inward pressure applied to it opens the circular through hole and provides an opening for material extrusion for the plastic connection mechanism.

[0012] When the lower pressure roller is rotating, the waterproof membrane roll will rotate along with it. At this time, due to the small distance between the upper pressure roller, the limiting roller and the lower pressure roller, and the thickness of the waterproof membrane itself, the cylinder on the lower pressure roller will be subjected to radial pressure and slightly displaced inward, so that the material inside the two ends of the lower pressure roller is squeezed out of the cylinder, and the internal material will be discharged due to the centrifugal extrusion force. After the waterproof membrane is separated from the outer surface of the lower pressure roller, it will not be subjected to pressure, so that the internal material will not be squeezed out, thereby preventing material waste.

[0013] An opening is provided at the bottom of the outer side of the cylinder, a limiting ring is provided on the outer side around the top of the cylinder, and an annular cylinder is fixedly installed on the outer side of the bottom of the cylinder. A pressure spring is clamped between the inside of the annular cylinder and the limiting ring. The cylinder moves radially inward by external pressure and moves the opening to below the bottom of the annular cylinder, so that the material passes through the cylinder and the coiled material and adheres to each other, so that the plastic connection mechanism can evenly adhere the material to the coiled material.

[0014] As the cylinder is under pressure, it will move inward. After it is separated from the waterproof membrane, the pressure will decrease. Due to the elastic potential energy of the pressure spring and the extrusion force of the internal material, the cylinder will move radially outward, thereby preventing the material from being squeezed out from the inside of the cylinder, avoiding the material on the ground that is not in contact with the waterproof membrane from being squeezed out, and preventing material waste. At the same time, when the waterproof membrane moves, it will drive the cylindrical protrusion formed inside the cylinder to separate from the cylinder, thereby bonding to the waterproof membrane and becoming a whole with the waterproof membrane.

[0015] Rotating disks are fixedly mounted at both ends of the rotating drum, arc-shaped blades are fixedly mounted on the rotating disks, and a plurality of discharge holes are opened on the rotating disks. The arc-shaped blades extrude the materials into shape through the centrifugal force generated by the rotation, and the plastic connection mechanism is quickly bonded.

[0016] The rotating disk on the rotating drum rotates to rotate the arc-shaped blades and squeeze the material flowing out of the discharge hole. The material is thrown into the inner walls of both ends of the lower pressure roller through centrifugal pressure, and the extrusion force generated by the rotating disk squeezes the material through the cylinder, so that it adheres to the waterproof membrane, thereby forming an array of small cylindrical protrusions on the membrane, thereby achieving adhesion of the waterproof membrane.

[0017] A spiral rod is rotatably installed inside the rotating drum, and both ends of the spiral rod are fixedly installed on the inner side of the rotating disk. The spiral directions of the two ends of the spiral rod are opposite. A material feeding hole is opened inside the spiral rod. The spiral rod transports the material to both sides of the rotating disk through spiral rotation, and extrude the material into shape through centrifugal extrusion, so as to provide a steady supply of material for the plastic connection mechanism.

[0018] In order to continuously bond the material to the waterproof membrane, the material must be transported to the inside of the drum through the feed hole in the middle of the spiral rod. The material entering the drum is generally in a heated fluid state with low fluidity. The spiral rotation pushes the material to flow to both ends of the spiral rod and is extruded from the discharge hole on the rotating disk, thereby achieving continuous transportation of the material and continuous bonding to both sides of the waterproof membrane.

[0019] The interior of the shaping roller is a hollow structure, and a spiral pipe is fixedly installed on the inner wall of the shaping roller. The spiral pipe cools and shapes the extruded material through a spiral water flow, thereby accelerating the adhesion speed of the plastic connection mechanism.

[0020] After an array of small circular protrusions are formed on both sides of the waterproof membrane, the cylindrical protrusions need to be cooled and formed by a forming roller so that the cylindrical protrusions adhered to both sides of the waterproof membrane can form a whole with the waterproof membrane, thereby ensuring the sealing performance during the subsequent bonding and splicing of the waterproof membrane and improving the waterproof performance of the waterproof membrane.

[0021] A water-leakage-proof pre-laid waterproofing membrane, comprising a protective layer, a waterproof layer, a self-adhesive layer, a granular layer and a cylindrical protrusion; the waterproof layer is fixedly mounted on the protective layer, the self-adhesive layer is fixedly mounted on the waterproof layer, the granular layer is fixedly mounted on the self-adhesive layer, and cylindrical protrusions are fixedly mounted on both sides of the self-adhesive layer, the cylindrical protrusions are closely cross-fitted with each other to form a sealing structure, and the two sides of the water-leakage-proof pre-laid waterproofing membrane are sealed and fastened by static friction and viscosity.

[0022] In order to make the waterproof membrane fit tightly, the cylindrical protrusions on the two waterproof membranes cooperate with each other so that the cylindrical protrusions can cross and fit tightly against each other. The static friction between the cylindrical protrusions makes the connection between the waterproof membranes more secure. At the same time, the cylindrical protrusions on the waterproof membranes are fixed by the glue on the cylindrical protrusions, making the connection between the waterproof membranes fit more tightly and improving the sealing performance between the joints of the waterproof membranes, thereby ensuring that the waterproof membranes will not leak.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention provides a plastic connection mechanism on the base. The spiral extrusion force generated by the rotation of the plastic connection mechanism adheres the material to the two sides of the roll material and forms a whole with the waterproof roll material, so that the waterproof roll material processing equipment not only adheres the waterproof roll material by applying adhesive, but also the static friction and viscosity between the cylindrical protrusions connect the two waterproof roll materials to each other, tightly fit to form a sealing structure, thereby improving the sealing performance between the waterproof roll materials and preventing water leakage of the waterproof roll materials.

[0025] 2. The present invention provides a rotating drum and a cylinder on the plastic connection mechanism. Through the cooperation between the rotating drum and the cylinder, the material is continuously extruded and evenly adhered to both sides of the waterproof membrane through the cylinder, so that the two waterproof membranes can be closely fitted to each other through the material of the adhesive, thereby improving the sealing performance between the waterproof membranes and, at the same time, improving the efficiency of adhesion.

[0026] 3. The present invention provides a shaping roller on the plastic-joining mechanism. Through the rotation of the shaping roller, the small cylindrical protrusion formed by adhesion can be quickly shaped on the shaping roller and form a whole with the waterproof membrane, thereby improving the strength and sealing performance of the waterproof membrane during adhesion and splicing, and preventing the waterproof membrane from detaching or leaking at the connection.

DETAILED DESCRIPTION

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1 As shown, a water-leakage-proof pre-laid waterproofing coiled material processing equipment comprises a base 1, a coiled material drum 2, a film pressing drum 3 and a winding drum 4; the coiled material drum 2 is rotatably mounted on the base 1, the film pressing drum 3 is rotatably mounted on the base 1, the winding drum 4 is rotatably mounted on the base 1, and also comprises a plastic connection mechanism 5, the plastic connection mechanism 5 is fixedly mounted on the base 1, and the plastic connection mechanism 5 rotates and extrudes the material by spiral rotation to plastically bond the material to the waterproofing coiled material, and is bonded and formed as a whole with the waterproofing coiled material.

[0041] When the leak-proof pre-laid waterproof membrane is being bonded, it first needs to be rotated by the membrane drum 2, and then pass through the plastic bonding mechanism 5, and the joints on both sides of the waterproof membrane are bonded to the small cylindrical protrusions 91 arranged in an array by the plastic bonding mechanism 5, and quickly cooled and formed. After the bonding is completed, a film is covered on both sides of the waterproof membrane by the film pressing drum 3, and finally the processed waterproof membrane is packaged and rolled up by the winding drum 4, so as to improve the sealing and waterproof performance of the joints of the waterproof membrane when the waterproof membrane is bonded and spliced.

[0042] like Figure 1 and Figure 2As shown, the plastic connection mechanism 5 includes an upper pressing roller 51, a lower pressing roller 52, a rotating drum 53, a limiting roller 54 and a shaping roller 55; the upper pressing roller 51 is rotatably installed on the base 1, and the lower pressing roller 52 is rotatably installed below the upper pressing roller 51. The lower pressing roller 52 rotates to uniformly extrude the material and form and adhere it to the two ends of the coil. The rotating drum 53 is rotatably installed in the lower pressing roller 52. The rotating drum 53 transports the material to the two ends of the lower pressing roller 52 through bidirectional spiral rotation; the limiting roller 54 is rotatably installed on one side of the lower pressing roller 52, and the shaping roller 55 is rotatably installed on one side of the limiting roller 54.

[0043] When the pre-laid waterproof coiled material is being processed, after the pre-laid waterproof coiled material enters the upper pressing roller 51 and the lower pressing roller 52 on the plastic connection mechanism 5, as the upper pressing roller 51 and the lower pressing roller 52 rotate in opposite directions, the waterproof coiled material will pass between the upper pressing roller 51 and the lower pressing roller 52. When the waterproof coiled material passes through, it will be subjected to the pressure of the upper pressing roller 51 and the limiting roller 54, so that the waterproof coiled material is always in close contact with the lower pressing roller 52, and the two sides of the waterproof coiled material are adhered by the lower pressing roller 52, and the material inside the lower pressing roller 52 is squeezed and adhered to the two sides of the waterproof coiled material, forming an array of small cylindrical protrusions 91, and passing through the limiting roller 54, and finally passing through the bottom of the limiting roller 54 to the shaping roller 55, thereby realizing the adhesion of the waterproof coiled material.

[0044] like Figure 2 and Figure 3 As shown, the interior of the lower pressing roller 52 is a hollow structure, and a plurality of circular through holes 521 are provided in a ring array centered on the axis at both ends of the lower pressing roller 52, and circular holes 522 are axially provided at both ends of the lower pressing roller 52. A cylinder 523 is fixedly installed in the circular through hole 521 on the lower pressing roller 52, and the cylinder 523 is subjected to radial inward pressure when the lower pressing roller 52 rotates, thereby opening the circular through hole 521 and providing an opening for material extrusion for the plastic connection mechanism 5.

[0045] During the rotation of the lower pressing roller 52, the waterproofing coil passes between the upper pressing roller 51 and the lower pressing roller 52, and finally comes out from between the lower pressing roller 52 and the limiting roller 54. The waterproofing coil covers the area of ​​the lower pressing roller 52. Due to the radial pressure, radial pressure is applied to the cylinder 523, causing the cylinder 523 to move inward, and causing the material inside the lower pressing roller 52 to be squeezed out through the cylinder 523, thereby adhering to both sides of the waterproofing coil and forming small cylindrical protrusions 91. As the lower pressing roller 52 rotates, the cylindrical protrusions 91 will detach from the cylinder 523, and the cylinder 523 detached from the waterproofing coil will move outward and prevent the material inside the lower pressing roller 52 from flowing out.

[0046] like Figure 8 and Fig. 9As shown, an opening 524 is provided at the bottom of the outer side of the cylinder 523, a limiting ring 525 is provided on the outer side around the top of the cylinder 523, and an annular cylinder 526 is fixedly installed on the outer side of the bottom of the cylinder 523. A pressure spring 527 is clamped between the inside of the annular cylinder 526 and the limiting ring 525. The cylinder 523 moves radially inward due to external pressure and moves the opening 524 to below the bottom of the annular cylinder 526, so that the material passes through the cylinder 523 and adheres to the coil, so that the plastic connection mechanism 5 can evenly adhere the material to the coil.

[0047] The lower pressure roller 52 rotates, thereby driving the waterproof membrane to rotate. The outer surfaces of both ends of the lower pressure roller 52 will be subjected to pressure, so that the cylinder 523 moves inward, and the limit ring 525 on the top of the cylinder 523 will compress the pressure spring 527. The opening 524 on the side of the cylinder 523 will move to the bottom of the annular cylinder 526 and exceed the bottom of the annular cylinder 526. Therefore, the material at the bottom of the annular cylinder 526 will be squeezed out through the opening 524 and flow out of the cylinder 523, thereby adhering the material to both sides of the waterproof membrane and forming an array of small cylindrical protrusions 91 on the waterproof membrane, so that the two pieces of waterproof membrane can cooperate with each other through the small cylindrical protrusions 91 and fit tightly, so that the sealing performance of the waterproof membrane sealing part is improved, and water leakage at the joint of the waterproof membrane is prevented.

[0048] like Figure 3 , Figure 4 and Figure 6 As shown, rotating disks 531 are fixedly installed at both ends of the rotating drum 53, and arc-shaped blades 532 are fixedly installed on the rotating disk 531. The rotating disk 531 is provided with a plurality of discharge holes 533. The arc-shaped blades 532 generate centrifugal force through rotation, and extrude the material into shape, and make the plastic connection mechanism 5 adhere quickly.

[0049] As the lower pressure roller 52 rotates, the rotating drum 53 will rotate along with the lower pressure roller 52, and the rotating disks 531 at both ends of the rotating drum 53 will rotate faster than the lower pressure roller 52, and will squeeze the material extruded from the discharge hole 533 on the rotating disk 531, so that the material is squeezed out through the arc-shaped blades 532 on the rotating disk 531, thereby achieving the extrusion and removal of the material.

[0050] like Figures 3 to 5 As shown, a screw rod 534 is rotatably installed inside the rotating drum 53, and the two ends of the screw rod 534 are fixedly installed on the inner side of the rotating disk 531. The spiral directions of the two ends of the screw rod 534 are opposite. A material feeding hole 535 is opened inside the screw rod 534. The screw rod 534 conveys the material to the two sides of the rotating disk 531 through spiral rotation, and extrude the material into shape through centrifugal extrusion, thereby providing a continuous supply of material for the plastic connection mechanism 5.

[0051] During the bonding process, the material will flow out from the feed hole 535 on the middle part of the screw rod 534 inside the drum 53, and the material after flowing out will accumulate inside the drum 53. As the screw rod 534 rotates, the material will be squeezed by the rotation of the screw rod 534, squeezed from the middle part of the screw rod 534 to both sides, and finally squeezed to the other side of the rotating disk 531 through the discharge hole 533 on the rotating disk 531, thereby realizing continuous transportation of the material and providing bonding material for the plastic connection mechanism 5.

[0052] like Figure 7 As shown, the interior of the shaping roller 55 is a hollow structure, and a spiral pipe 551 is fixedly installed on the inner wall of the shaping roller 55. The spiral pipe 551 cools and shapes the extruded material through a spiral water flow, thereby accelerating the adhesion speed of the plastic connection mechanism 5.

[0053] After the adhesion is completed, after the waterproof membrane moves from the lower pressure roller 52 to the limiting roller 54, the cylindrical protrusions 91 on both sides of the waterproof membrane will be quickly separated from the lower pressure roller 52 and moved to the shaping roller 55, and the water flow will pass through the spiral pipe 551 inside the shaping roller 55, and cool the waterproof membrane on the shaping roller 55, so that the small cylindrical protrusions 91 on both sides of the waterproof membrane are quickly cooled and shaped, so that the cylindrical protrusions 91 and the waterproof membrane form a whole, and finally, the cylindrical protrusions 91 of the waterproof membrane are covered with a protective film on one side through the film pressing cylinder 3, and then the waterproof membrane is stored and packaged through the winding cylinder 4, thereby completing the processing of the waterproof membrane.

[0054] like Fig.10 As shown, a leakproof pre-laid waterproof membrane comprises a protective layer 6, a waterproof layer 7, a self-adhesive layer 8, a granular layer 9 and a cylindrical protrusion 91; the waterproof layer 7 is fixedly mounted on the protective layer 6, the self-adhesive layer 8 is fixedly mounted on the waterproof layer 7, the granular layer 9 is fixedly mounted on the self-adhesive layer 8, and cylindrical protrusions 91 are fixedly mounted on both sides of the self-adhesive layer 8, respectively, and the cylindrical protrusions 91 are closely cross-fitted with each other to form a sealing structure, and the two sides of the leakproof pre-laid waterproof membrane are sealed and fastened by static friction and viscosity.

[0055] The connecting edges of the two waterproof membranes are aligned through the connecting edges on both sides of the leakproof pre-laid waterproof membrane, and then the protective films on both sides of the waterproof membrane are torn off, and the upper waterproof membrane is pressed down onto the bottom waterproof membrane. The cylindrical protrusions 91 on the waterproof membrane cross-fit with each other and are bonded by the adhesive on the cylindrical protrusions 91, thereby ensuring that the two sides of the leakproof pre-laid waterproof membrane are sealed and fastened, and preventing leakage and the like from occurring at the connecting points on both sides of the leakproof pre-laid waterproof membrane.

[0056] During operation, when the water leakage-proof pre-laid waterproofing roll is being bonded, it first needs to rotate the roll drum 2, and then pass through the plastic connection mechanism 5. After the pre-laid waterproofing roll enters the upper pressing roller 51 and the lower pressing roller 52 on the plastic connection mechanism 5, as the upper pressing roller 51 and the lower pressing roller 52 rotate in opposite directions, the waterproofing roll will pass between the upper pressing roller 51 and the lower pressing roller 52. When the waterproofing roll passes, it will be subjected to the pressure of the upper pressing roller 51 and the limiting roller 54, so that the waterproofing roll is always in close contact with the lower pressing roller 52, and the waterproofing roll covers the area of ​​the lower pressing roller 52. The pressure in the radial direction will apply radial pressure to the cylinder 523, causing the cylinder 523 to move inward, and the limit ring 525 on the top of the cylinder 523 will compress the pressure spring 527, and the opening 524 on the side of the cylinder 523 will move to the bottom of the annular cylinder 526 and exceed the bottom of the annular cylinder 526, so that the material at the bottom of the annular cylinder 526 will be squeezed out through the opening 524 and flow out of the cylinder 523, thereby adhering the material to both sides of the waterproof membrane and forming an array of small cylindrical protrusions 91 on the waterproof membrane, thereby making the two pieces of waterproof membrane.

[0057] At the same time, as the lower pressure roller 52 rotates, the rotating drum 53 will rotate with the lower pressure roller 52, and the rotating disks 531 at both ends of the rotating drum 53 will rotate faster than the lower pressure roller 52, and the material will flow out from the feeding hole 535 on the middle part of the screw rod 534 inside the rotating drum 53, and the material after flowing out will accumulate inside the rotating drum 53. As the screw rod 534 rotates, the material will be squeezed by the rotation of the screw rod 534, squeezed from the middle part of the screw rod 534 to both sides, and finally squeezed to the other side of the rotating disk 531 through the discharge hole 533 on the rotating disk 531, and the material extruded from the discharge hole 533 on the rotating disk 531 will be squeezed, so that the material is squeezed into the inside of the cylinder 523 through the arc-shaped blades 532 on the rotating disk 531, and is extruded through the cylinder 523 and adhered to the waterproof membrane to form a cylindrical protrusion 91.

[0058] After the adhesion is completed, after the waterproof coiled material moves from the lower pressure roller 52 to the limiting roller 54, the cylindrical protrusions 91 on both sides of the waterproof coiled material will be quickly separated from the cylinder 523 on the lower pressure roller 52 and move to the shaping roller 55, and the water flow will pass through the spiral pipe 551 inside the shaping roller 55, and cool the waterproof coiled material on the shaping roller 55, so that the small cylindrical protrusions 91 on both sides of the waterproof coiled material are quickly cooled and shaped, so that the cylindrical protrusions 91 and the waterproof coiled material form a whole, and finally, the cylindrical protrusions 91 of the waterproof coiled material are covered with a protective film on one side through the film pressing roller 3, and then the waterproof coiled material is stored and packaged through the winding roller 4, thereby completing the processing of the waterproof coiled material.

[0059] The connecting edges of the two waterproof membranes are aligned through the connecting edges on both sides of the leakproof pre-laid waterproof membrane, and then the protective films on both sides of the waterproof membrane are torn off, and the upper waterproof membrane is pressed down onto the bottom waterproof membrane. The cylindrical protrusions 91 on the waterproof membrane cross-fit with each other and are bonded by the adhesive on the cylindrical protrusions 91, thereby ensuring that the two sides of the leakproof pre-laid waterproof membrane are sealed and fastened, and preventing leakage and the like from occurring at the connecting points on both sides of the leakproof pre-laid waterproof membrane.
