Description

Technical Field

[0001] The utility model relates to the technical field of waterproof materials, in particular to an anti-seepage waterproof cushion layer combining rigid waterproofing with flexible waterproofing. Background Art

[0002] The existing concrete waterproofing pad has a cement mixture on the upper layer and a waterproof layer on the lower layer. After contacting with water, the cement mixture can solidify quickly to form a rigid waterproof. If water penetrates the cement mixture and reaches the waterproof layer, the waterproof layer can further prevent the water from flowing to the base below.

[0003] However, waterproof cushions are generally used in ditches, slope protection, ponds, reservoirs, wetlands and other places. If the concrete waterproof cushion is always in water or a humid environment, the viscosity of the glue will decrease, causing the waterproof layer to fall off, affecting the service life and use effect of the product. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an anti-seepage waterproof cushion layer which combines rigid waterproofness with flexible waterproofness, which not only ensures the waterproof effect, but also prevents the waterproof layer from falling off.

[0005] The technical solution of this utility model is as follows:

[0006] An anti-seepage waterproof cushion layer combining rigid waterproof and flexible waterproof, comprising:

[0007] The permeable layer, located at the top, is filled with a cement mixture;

[0008] The anti-adhesive layer, located below the permeable layer, is reactive sand, or reactive coating, or water-soluble film;

[0009] A healing layer, including an adhesive, is applied below the anti-adhesive layer;

[0010] A waterproof layer, pasted under the healing layer;

[0011] The penetration layer, the anti-adhesive layer, the healing layer and the waterproof layer are punctured and sutured into an integral structure by using a needle puncture technique.

[0012] in,

[0013] The permeable layer includes a 3D mesh fiber fabric with a thickness of 3mm-30mm. The upper surface is a base fabric for water infiltration and preventing cement mixture from flowing out, and the lower surface is a mesh for filling cement mixture, and the middle is connected by fiber lines.

[0014] The cement mixture includes cement, aggregate and solidifying agent, and a vibrating device is used to make the cement mixture be filled evenly in the permeable layer.

[0015] The reactive sand includes silicon dioxide. The reactive coating includes acrylic emulsion. The water-soluble film includes polyvinyl alcohol.

[0016] The thickness of the anti-adhesive layer is between 0.01mm and 0.5mm.

[0017] The healing layer material is one of pressure-sensitive adhesive, butyl adhesive or asphalt adhesive. When the needle pierces the waterproof layer, it can tightly wrap the fiber line, thereby preventing water droplets from seeping along the fiber line during the hydration process, thereby offsetting the water seepage problem that may be caused by the waterproof layer being pierced by needles.

[0018] The waterproof layer is made of polymer waterproof materials, such as HDPE, LDPE, LLDPE, PVC, EPDM, TPO, etc.

[0019] Through the above design, the utility model combines rigid waterproofing with flexible waterproofing and adopts overall acupuncture technology to puncture and sew the penetration layer, cement mixture, anti-adhesive layer, healing layer and waterproof layer into an integral structure, which effectively solves the problem of waterproof layer falling off.

[0020] When in use, the cement mixture solidifies when it comes into contact with water and reacts with the anti-adhesive layer. After the anti-adhesive layer reacts with the cement mixture, it can fill the tiny pores in the cement to prevent water penetration, thereby promoting cement solidification and forming rigid waterproofing.

[0021] The healing layer will tightly wrap the fiber lines that pass vertically through it, thereby preventing water from seeping downward along the fiber lines. The waterproof layer below can further ensure the waterproof effect and form flexible waterproofing.

[0022] In this way, the combination of rigid waterproofing and flexible waterproofing not only ensures the waterproof effect, but also prevents the waterproof layer from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1 As shown, this embodiment provides an anti-seepage waterproof cushion layer combining rigid waterproofing and flexible waterproofing, including a permeable layer-cement mixture-anti-adhesive layer-healing layer-waterproof layer.

[0028] Specifically, from top to bottom:

[0029] A permeable layer 1, located at the uppermost layer, which is filled with a cement mixture 2;

[0030] The anti-adhesive layer 3 is located below the permeable layer 1 and is reactive sand, or reactive coating, or water-soluble film;

[0031] A healing layer 4, comprising an adhesive, is coated below the anti-adhesive layer 3;

[0032] A waterproof layer 5 is pasted under the healing layer 4;

[0033] The permeable layer 1, the anti-adhesive layer 3, the healing layer 4 and the waterproof layer 5 are punctured and sewn into an integral structure by needle puncture technology, thereby preventing the bottom backing from falling off and improving the service life and use effect of the anti-seepage and waterproof cushion layer.

[0034] in,

[0035] The permeable layer 1 adopts 3D mesh fiber fabric, which is not only water-permeable but also provides good support.

[0036] Specifically, the thickness of the permeable layer 1 is between 3mm and 30mm, the upper surface of which is a base fabric for water infiltration and preventing the cement mixture from flowing out, and the lower surface is a mesh for filling the cement mixture, and the middle is connected by fiber lines. The base fabric material can be PET and other materials, and the mesh aperture is between 4mm and 10mm.

[0037] The cement mixture 2 includes cement, aggregate and coagulant, and a vibration device is used to uniformly fill the cement mixture 2 in the permeable layer 1. The specific composition ratio can be appropriately adjusted as needed, which is a prior art and will not be described in detail.

[0038] The function of the anti-adhesive layer 3 is that when the cement mixture solidifies in water, it reacts chemically with the concrete and firmly adheres together. A variety of materials can be selected. The thickness can be between 0.01mm and 0.5mm.

[0039] When reactive sand is used, silica may be used.

[0040] When reactive coatings are used, acrylic emulsions may be used.

[0041] When a water-soluble film is used, polyvinyl alcohol can be used.

[0042] The material of the healing layer 4 is one of pressure-sensitive adhesive, butyl adhesive or asphalt adhesive. Since the present invention adopts the integral needle-punching technology, the permeable layer-cement mixture-anti-adhesive layer-healing layer-waterproof layer are firmly sewn together to prevent the backing from falling off. When the waterproof layer is punctured, the waterproof effect will inevitably be affected. The use of the healing layer can tightly wrap the fiber line when the needle punctures the waterproof layer 5, thereby preventing water droplets from seeping along the fiber line during the hydration process, thereby offsetting the water seepage problem that may be caused by the waterproof layer 5 being punctured.

[0043] The thickness of the healing layer is between 0.01mm and 1mm.

[0044] The waterproof layer 5 is made of polymer waterproof material, such as HDPE, LDPE, LLDPE, PVC, EPDM, TPO, etc. It can effectively prevent water from penetrating out of the waterproof cushion layer during the hydration process, affecting the hydration effect and timeliness. It is also convenient for welding, reducing the damage to the healing layer and the waterproof layer caused by the use of self-tapping screws.

[0045] The anti-seepage and waterproof cushion provided in this embodiment is a multi-layer structure. The anti-adhesive layer and the cement mixture are firmly adhered together after encountering water, and the healing layer is adhered between the anti-adhesive layer and the waterproof layer, so that the multi-layer structure forms a complete waterproof cushion product after solidification, realizing the perfect combination of rigid waterproof and flexible waterproof, and better ensuring the timeliness and effect of waterproof and anti-seepage. The backing will not fall off and has a longer service life.
