[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The following is combined with Figure 1 Detailed description, a method for preparing water-stopping and anti-seepage concrete, the method comprising the following steps:

[0033] Step 1: Add cement, fine sand and water into the feeding pipe on the preparation device, and add coarse aggregate into the adding pipe on the preparation device. Finally, cement, fine sand, water and coarse aggregate will enter the mixing barrel on the preparation device.

[0034] Step 2: Stirring and mixing the various materials in the mixing barrel;

[0035] Step 3: Filter the stirred material;

[0036] Step 4: Extrude the filtered material to complete the preparation of water-stopping and anti-seepage concrete.

[0037] The following is combined with Figure 2-9 In detail, the preparation device includes a mixing barrel 101, an addition tube 102, a feeding tube 103, a reduction motor 1104, a stirring shaft 105, a spiral stirring plate 106, a filtering element and an extrusion element. The addition tube 102 is fixedly connected to the mixing barrel 101 by welding, the feeding tube 103 is fixedly connected to the mixing barrel 101 by welding, the reduction motor 1104 is fixedly connected to the mixing barrel 101 through a flange plate, the stirring shaft 105 is fixedly connected to the output shaft of the reduction motor 1104 by welding, the spiral stirring plate 106 is fixedly connected to the stirring shaft 105 by welding, the filtering element is fixedly connected to the mixing barrel 101 by threads, and the extrusion element is connected to the filtering element.

[0038] Furthermore, the mixing barrel 101 is placed at an angle, which is convenient for mixing various materials in the mixing barrel 101 and for discharging various material mixtures. The mixing barrel 101 can provide storage space for cement, fine sand, water and coarse aggregate, and can stir and mix various materials in the mixing barrel 101. The adding pipe 102 and the feeding pipe 103 are both connected to the mixing barrel 101. The feeding pipe 103 is provided with a cone to facilitate the addition of materials. Cement, fine sand and water are added to the feeding pipe 103. Finally, the cement, fine sand and water entering the feeding pipe 103 will enter the mixing barrel 101, and the coarse aggregate will be discharged. Aggregate is added into the adding pipe 102, and the coarse aggregate entering into the adding pipe 102 will enter into the mixing barrel 101. After the reduction motor 1104 is started, the stirring horizontal shaft 105 can be driven to rotate, and the rotating stirring horizontal shaft 105 will drive the spiral stirring plate 106 to rotate. When the spiral stirring plate 106 rotates counterclockwise, it will drive the various materials in the mixing barrel 101 to move upward, play a transposition processing of the various materials, and realize the stirring processing of the various materials. When the various materials in the mixing barrel 101 are mixed, the spiral stirring plate 106 is allowed to rotate clockwise to realize the extrusion processing of the various materials. The mixed materials are squeezed into the filter component. When multiple materials pass through the filter component, the multiple materials are filtered and removed. The gaps between the multiple materials are further reduced to ensure that the multiple materials have better water-stopping and anti-permeability properties. Finally, the multiple materials will pass through the extrusion component. In the process of multiple materials passing through the extrusion component, the multiple materials will be extruded and further reduced. Cement, fine sand, water and coarse aggregate are added to the mixing barrel 101, and the reduction motor I104 is started counterclockwise to drive the spiral The stirring plate 106 rotates counterclockwise to stir the cement, fine sand, water and coarse aggregate in the mixing barrel 101. When the various materials are mixed, the reduction motor I104 is started clockwise, and the various materials in the mixing barrel 101 are extruded by the clockwise rotating spiral stirring plate 106, so that the various materials enter the extrusion component to achieve filtering of the various materials. The various materials to be filtered enter the extrusion component to achieve extrusion of the various materials again, further reducing the gaps between the various materials, enhancing the water-stopping and anti-seepage properties of the concrete, and completing the preparation of the water-stopping and anti-seepage concrete.

[0039] The following is combined with Figure 2-5 In detail, the preparation device also includes a plurality of transverse scraping stirring plates 201 and supporting legs 202. The plurality of transverse scraping stirring plates 201 are evenly and fixedly connected to the spiral stirring plates 106 by welding, and the supporting legs 202 are fixedly connected to the mixing barrel 101 by welding.

[0040] Furthermore, multiple horizontal scraping stirring plates 201 are in contact with the inner wall of the mixing barrel 101. When the spiral stirring plates 106 rotate, the multiple horizontal scraping stirring plates 201 will scrape the inner wall of the mixing barrel 101, further preventing various materials from sticking to the inner wall of the mixing barrel 101, and can also drive various materials to move, further assisting the spiral stirring plates 106 in mixing various materials, shortening the preparation time of concrete, and the support legs 202 play a supporting and fixing role, so that the mixing barrel 101 can be placed stably on the ground.

[0041] According to the instruction manual Figure 2 , 6 As described in detail in Figures 7 and 8, the filter component includes a conical storage cavity 301, a filter plate 302 and a discharge pipe 303. The conical storage cavity 301 is fixedly connected to the mixing barrel 101 by threads, the filter plate 302 is fixedly connected to the conical storage cavity 301 by welding, and the discharge pipe 303 is fixedly connected to the conical storage cavity 301 by welding.

[0042] Furthermore, the mixed materials will enter the conical storage cavity 301. After entering the conical storage cavity 301, the materials will first contact the filter plate 302, and the filter plate 302 will be used to filter and screen the materials to remove large pieces of materials. This ensures that there are no large pieces of materials entering the conical storage cavity 301, and reduces the gaps between the materials. Finally, the materials will be discharged from the opening below the discharge pipe 303.

[0043] According to the instruction manual Figure 2 and 6 -8 is described in detail, the extrusion component includes a transverse support plate 401, a deflection plate 402 and a plurality of extrusion rotating columns 403, the transverse support plate 401 is fixedly connected to the conical storage cavity 301 by welding, the deflection plate 402 is connected to the transverse support plate 401 by axial rotation, and the plurality of extrusion rotating columns 403 are evenly fixedly connected to the deflection plate 402 by welding.

[0044] Furthermore, a reduction motor II is fixedly connected to the cross support plate 401, and the output shaft of the reduction motor II is fixedly connected to the deflection plate 402. When the reduction motor II is started, the deflection plate 402 will be driven to rotate, and the rotating deflection plate 402 will drive the multiple extrusion rotating columns 403 to rotate. When the multiple extrusion rotating columns 403 rotate, the various materials entering the discharge pipe 303 will be extruded, further reducing the gaps between the various materials and improving the water-stopping and anti-permeability of the concrete.

[0045] According to the instruction manual Figure 2 , 910, the preparation device further comprises a grinding straight cavity 501 and a grinding roller 502, the grinding straight cavity 501 is fixedly connected to the adding pipe 102 by welding and is in communication, and the grinding roller 502 is connected in the grinding straight cavity 501.

[0046] Furthermore, coarse aggregate is added into the grinding straight cavity 501, and the grinding roller 502 is rotated in the grinding straight cavity 501. The rotating grinding roller 502 can grind the coarse aggregate in the grinding straight cavity 501, further reducing the diameter of the coarse aggregate and ensuring that the coarse aggregate becomes small pieces. In this way, the diameter of the coarse aggregate can be limited from the perspective of material selection, preventing large pieces of coarse aggregate from being mixed with various materials and affecting the water-stopping and anti-permeability of the concrete. In addition, the use of finer coarse aggregate is also convenient for mixing with various materials, shortening the preparation cycle of the water-stopping and anti-permeability concrete.

[0047] According to the instruction manual Figure 2 , 9 10 is described in detail, the preparation device also includes a cross-support plate 601, a transfer support plate 602, a plurality of lifting slides 603 and a lifting screw 604, the cross-support plate 601 is fixedly connected to the grinding straight cavity 501 by welding, the transfer support plate 602 is rotatably connected to the cross-support plate 601 through a bearing hole, a plurality of lifting slides 603 are evenly fixedly connected to the transfer support plate 602 by welding, the grinding roller 502 is slidably connected to the plurality of lifting slides 603, the lifting screw 604 is rotatably connected to the transfer support plate 602 through a circular hole, and the grinding roller 502 is connected to the lifting screw 604 by threads.

[0048] Furthermore, the cross support plate 601 can provide a rotating space for the transfer support plate 602, and the transfer support plate 602 can provide a fixed space for multiple lifting slides 603. The grinding roller 502 is limited by multiple lifting slides 603, so that the grinding roller 502 can rotate along with the transfer support plate 602. When the lifting screw 604 is rotated, the grinding roller 502 will be driven to rise and fall, thereby changing the size of the gap between the grinding roller 502 and the grinding straight cavity 501, thereby changing the diameter of the coarse aggregate when being ground. According to the processing of water-stopping and anti-seepage concrete of different qualities, the lifting screw 604 is rotated to change the distance between the grinding roller 502 and the grinding straight cavity 501, thereby grinding aggregates of different diameters.

[0049] According to the instruction manual Figure 2 , 910 is described in detail, the preparation device also includes a vertical cavity 701, a transmission worm 702, a linkage gear 703 and a main rotating gear 704, the vertical cavity 701 is fixedly connected to the transfer support plate 602 by welding, the transmission worm 702 is rotatably connected to the vertical cavity 701 through a bearing hole, the lifting screw 604 is transmission-connected to the transmission worm 702, the linkage gear 703 is fixedly connected to the vertical cavity 701 by a plurality of bolts and nuts, the main rotating gear 704 is rotationally connected to the cross support plate 601 through an axis, and the linkage gear 703 is meshingly transmission-connected to the main rotating gear 704.

[0050] Furthermore, the vertical cavity 701 can provide a rotation space for the transmission worm 702. A transmission worm wheel is fixedly connected above the lifting screw 604. The transmission worm 702 is meshed and connected with the transmission worm wheel. The transmission worm 702 can be rotated to drive the lifting screw 604 to rotate through the worm wheel, thereby driving the grinding roller 502 to lift and lower. The vertical cavity 701 can be driven to rotate by the linkage gear 703. When the vertical cavity 701 rotates, it will drive the transfer support plate 602 to rotate, and finally drive the grinding roller 502 to rotate, and finally realize the grinding of coarse aggregate and turn the coarse aggregate into finer aggregate. A reduction motor III is fixedly connected to the cross support plate 601, and the output shaft of the reduction motor III is fixedly connected to the main gear 704. After starting the reduction motor III, the main gear 704 will be driven to rotate, and the rotating main gear 704 will drive the linkage gear 703 to rotate, thereby driving the vertical cavity 701 to rotate.

[0051] According to the instruction manual Figure 2 , 9 10, the preparation device further comprises a shielding cover cavity 801, and the shielding cover cavity 801 is fixedly connected to the cross support plate 601 by welding.

[0052] Furthermore, the shielding cover cavity 801 is used to shield the parts to prevent the coarse aggregate from entering the grinding straight cavity 501 and falling directly into the vertical cavity 701. If the coarse aggregate falls directly into the vertical cavity 701, it will affect the linkage between the parts.
