[0002] Waterproof coiled materials are mainly used in building walls, roofs, tunnels, highways, landfills, etc. They are flexible building materials that can be curled into rolls and play a role in resisting external rainwater and groundwater seepage. As a leak-free connection between the project foundation and the building, they are the first barrier for the overall project waterproofing and play a crucial role in the entire project.

[0003] After retrieval, a Chinese patent with the patent publication number CN215106709U discloses a new waterproof coiled material laying and fixing device for construction engineering technology, including a working box.

A waterproof coiled material body is movably connected between the opposite sides of the two connecting rods. When moving through the handle, the exhaust fan is started, and the dust is sucked into the collection bin through the exhaust duct by the exhaust fan. Subsequently, the waterproof coiled material body is stretched through the limiting structure to start laying. The limiting structure effectively prevents the waterproof coiled material body from contacting the working box during laying. The overall structure is simple, the laying ground is cleaned, and the work efficiency is improved.

[0025] Please refer to Figures 1-4, an embodiment provided by the utility model: a waterproof coiled material laying and fixing device for construction engineering, which includes a working box 1, a transmission mechanism 8 and a leveling mechanism 9. Universal wheels 3 are installed on both sides of the bottom of the working box 1. A limiting roller 14 is rotatably arranged between the two universal wheels 3. A pull handle 2 is fixedly connected to one side of the working box 1. A transparent window 7 is fixedly arranged on the front end face of the working box 1. An installation cavity 10 is arranged inside the working box 1. A material guiding port 12 communicating with each other is opened at the bottom of the installation cavity 10. A groove 4 communicating with each other is opened at the top of the installation cavity 10. A cover plate 6 is movably arranged inside the groove 4. A handle 5 is fixedly connected to the top of the cover plate 6. A U-shaped plate 13 is fixedly connected to the bottom of the cover plate 6. A waterproof coiled material main body 11 is movably arranged inside the U-shaped plate 13. Transmission mechanisms 8 are arranged at both ends of the waterproof coiled material main body 11. The transmission mechanism 8 includes a positive and negative motor 806, and the positive and negative motor 806 is fixedly installed at the upper end inside the U-shaped plate 13. The output end of the positive and negative motor 806 is fixedly connected to a bidirectional screw rod 805. A moving block 802 is threadedly connected to the outer wall of the bidirectional screw rod 805. A limiting rod 801 penetrates through the upper end surface of the moving block 802 in an active manner. A moving plate 803 is fixedly connected to the bottom of the moving block 802. One ends of the two moving plates 803 close to each other are rotatably connected to a positioning block 804 through bearings. A blocking plate 807 is fixedly sleeved on the outer wall of the positioning block 804;

[0026] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, when in use, when a new waterproof coiled material needs to be installed after the waterproof coiled material is used up, pull up the handle 5 until the U-shaped plate 13 disengages from the installation cavity 10. Then place the new waterproof coiled material between the two positioning blocks 804 and align the positioning blocks 804 with the through holes on both sides of the waterproof coiled material. Then, the output end of the positive and negative motor 806 can be used to drive the bidirectional screw rod 805 to rotate. The rotation of the bidirectional screw rod 805 drives the two moving blocks 802 to move in the direction of approaching each other. The movement of the two moving blocks 802 drives the two positioning blocks 804 to move in the direction of approaching each other through the two moving plates 803 until the two positioning blocks 804 are respectively inserted into the through holes on both sides of the waterproof coiled material, thus completing the fixation of the waterproof coiled material. Then place the cover plate 6 directly above the groove 4 and align the U-shaped plate 13 with the installation cavity 10. Then move the cover plate 6 downward until the cover plate 6 completely enters the groove 4, thus completing the replacement of the waterproof coiled material, solving the problem that after the waterproof coiled material is used up, it is not convenient to quickly install a new waterproof coiled material, which will prolong the laying time, the laying efficiency is low, and it is difficult to well meet the usage requirements of people;

[0027] Among them: Through the setting of the limiting roller 14, it can effectively prevent the waterproof coiled material from contacting the working box 1 during laying, and in cooperation with the leveling wheel 903, it can improve the laying efficiency.

[0028] On the other side of the installation cavity 10, a leveling mechanism 9 is provided. The leveling mechanism 9 includes a fixed groove 902. An activity plate 901 is movably arranged inside the fixed groove 902. A hydraulic cylinder 904 is installed on the top of the activity plate 901, and the output end of the hydraulic cylinder 904 is fixedly connected to the top of the activity plate 901. Sliding grooves 906 are formed on both sides of the activity plate 901. A slider 905 is slidably connected to the inner wall of the sliding groove 906, and the slider 905 is fixedly connected to the activity plate 901. A leveling wheel 903 is installed at the bottom of the activity plate 901;

[0029] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, during use, during the laying process of the waterproof coiled material, the output end of the hydraulic cylinder 904 can be used to drive the activity plate 901 to move downward. The downward movement of the activity plate 901 drives the leveling wheel 903 to move downward until it contacts the upper surface of the waterproof coiled material. Then the leveling wheel 903 will continue to move downward to make the waterproof coiled material fit the ground, thereby improving the laying effect and further improving the practicability of the device.

[0030] Working principle: In this application, when a new waterproof coiled material needs to be installed after the waterproof coiled material is used up, pull the handle 5 upward until the U-shaped plate 13 disengages from the installation cavity 10. Then place the new waterproof coiled material between the two positioning blocks 804 and align the positioning blocks 804 with the through holes on both sides of the waterproof coiled material. Then the output end of the forward and reverse motor 806 can be used to drive the bidirectional screw 805 to rotate. The rotation of the bidirectional screw 805 drives the two moving blocks 802 to move in the direction of approaching each other. The movement of the two moving blocks 802 drives the two positioning blocks 804 to move in the direction of approaching each other through the two moving plates 803 until the two positioning blocks 804 are respectively inserted into the through holes on both sides of the waterproof coiled material, thereby completing the fixation of the waterproof coiled material. Then place the cover plate 6 directly above the groove 4 and align the U-shaped plate 13 with the installation cavity 10. Then move the cover plate 6 downward until the cover plate 6 completely enters the groove 4, thereby completing the replacement of the waterproof coiled material. Secondly, during the laying process of the waterproof coiled material, the output end of the hydraulic cylinder 904 can be used to drive the activity plate 901 to move downward. The downward movement of the activity plate 901 drives the leveling wheel 903 to move downward until it contacts the upper surface of the waterproof coiled material. Then the leveling wheel 903 will continue to move downward to make the waterproof coiled material fit the ground, thereby improving the laying effect and further improving the practicability of the device.
