Description

Technical Field

[0001] The present application relates to the technical field of mixed treatment methods for anti-permeability membranes, and in particular to a mixed treatment method for anti-permeability membranes during construction. Background Art

[0002] The anti-permeability membrane is a special material mainly used to isolate water and dissolved pollutants, and is widely used in water treatment, waste treatment, construction and civil engineering. It can effectively prevent the penetration of liquids while allowing gases to pass through, thereby protecting the environment and structures from water damage.

[0003] The construction of anti-seepage membrane is a professional work, which requires specific steps and methods to ensure the quality of construction. The following are the basic processes and key points of construction:

[0004] Surface treatment: First, clean the surface, remove sharp objects, pumice, etc., and ensure that the surface is flat and undamaged. The surface should be dry and flat, and any damaged or uneven areas should be repaired.

[0005] Laying the isolation layer: First lay a polyethylene isolation net or sand on the wet base surface to prevent the anti-seepage membrane from directly contacting the base surface.

[0006] Laying the anti-seepage membrane: Lay the anti-seepage membrane on the isolation layer and make sure there are no folds, bubbles or other defects. When laying, extend it from the bottom to the high position, do not pull it too tight, and leave a certain margin to prepare for local sinking and stretching.

[0007] Corner treatment: The anti-seepage membrane along the corners of walls and pipes should avoid sharp corners and adopt multi-piece splicing or drilling treatment.

[0008] Connection of waterproof membrane: Use hot-melt connection tape or cold-adhesive connection tape to directly weld or bond the wide waterproof membrane. Welding processes include hot wedge welding, heat fusion welding, extrusion welding and hot air gun welding, etc. Each welding process has its applicable weld and construction parameters.

[0009] Anchor structure construction: The surrounding structure of the anti-seepage membrane is constructed. The anchor holes are made with specific equipment, the bolts are fixed with chemical anchoring agents, and nuts are used to fix the angle steel and bolts. Before construction, the foundation surface is cleaned and the uneven parts are trimmed.

[0010] During the construction of the anti-seepage membrane, especially during the connection of the anti-seepage membrane, it is difficult to achieve the connection stability of the entire anti-seepage membrane on the covered surface only by simple hot-melt welding. Furthermore, even if multiple anti-seepage membranes are tightly connected at the connection points, there will be shaking above the covered surface. In a way, the overall installation stability of the anti-seepage membrane cannot be guaranteed only by stable installation at the end corners or edges. Summary of the invention

[0011] In an exemplary embodiment of the present application, a mixing method for an impermeable membrane during construction is provided, wherein the construction and layout stability of the impermeable membrane on the base surface is improved by mixing the adhesive in the groove at the joint of the impermeable membrane.

[0012] The present application provides a mixing treatment method for an anti-permeability membrane during construction, comprising:

[0013] S1: opening a groove on the base surface and filling the groove with a binder;

[0014] S2: immersing the outer edge of the first end of the first anti-permeability membrane into the groove and contacting with the adhesive, a plurality of first through holes are provided on one side of the first end of the first anti-permeability membrane, and the plurality of first through holes are arranged at intervals along the length direction of the first end of the first anti-permeability membrane, and part of the adhesive flows from the groove to the top surface of the first end of the first anti-permeability membrane through the first through holes;

[0015] S3: placing the first end of the second anti-permeation membrane above the first end of the first anti-permeation membrane, a plurality of second through holes are arranged on one side of the first end of the first anti-permeation membrane, and the plurality of second through holes are arranged at intervals along the length direction of the first end of the second anti-permeation membrane, and when the first end of the second anti-permeation membrane is placed above the first end of the first anti-permeation membrane, the first through holes and the second through holes are arranged at intervals and staggered along the length direction of the first end of the first anti-permeation membrane;

[0016] S4: attaching the outer edge of the first end of the second anti-permeability membrane to the upper side of the first end of the first anti-permeability membrane, and hot-melt welding the outer edge of the first end of the second anti-permeability membrane to the first end of the first anti-permeability membrane;

[0017] S5: heat-melt-weld the second through hole and the surface of the first end of the first anti-permeability membrane along the length direction of the first end of the second anti-permeability membrane.

[0018] Furthermore, the groove is recessed on the base surface, and the adhesive is filled at least to the top surface of the groove in the height direction.

[0019] Further, the aperture size of the first through hole is larger than the aperture size of the second through hole.

[0020] Furthermore, a distance between two adjacent first through holes is greater than twice a diameter of the second through hole.

[0021] Furthermore, the linear distance between the center of the first through hole and the outer edge of one side of the first end of the first anti-permeability membrane ranges from 10 mm to 15 mm.

[0022] Furthermore, after hot-melt welding the outer edge of the first end of the second anti-permeability membrane to the first end of the first anti-permeability membrane, wait for 3 minutes, and then hot-melt weld the first end of the second anti-permeability membrane along its length direction with the second through hole and the surface of the first end of the first anti-permeability membrane.

[0023] Furthermore, when the first end of the second anti-permeability membrane is placed above the first end of the first anti-permeability membrane, the plurality of first through holes and the plurality of second through holes are arranged along the same straight line.

[0024] The embodiments of the present application have the following beneficial effects: by respectively setting the first through hole and the second through hole on the first anti-permeability membrane and the second anti-permeability membrane, the adhesive in the groove can flow through the first through hole and the second through hole respectively to between the first anti-permeability membrane and the second anti-permeability membrane to achieve adhesive connection, and at the same time, the mixed flow of the adhesive can be achieved through the first through hole and the second through hole set in an offset manner, so that the adhesive can be filled and attached between the first anti-permeability membrane and the second anti-permeability membrane, and the waste of adhesive material that affects the quality of hot melt welding due to excessive flow of adhesive between the first anti-permeability membrane and the second anti-permeability membrane can be avoided, thereby improving the mixing and dispersion stability of the adhesive of the anti-permeability membrane during the construction process and making full use of the adhesive guided and transported by the first through hole and the second through hole to improve the connection stability of the first anti-permeability membrane and the second anti-permeability membrane.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiment of the present application.

[0031] refer to Figure 1 As shown, the present application provides a method for mixing an anti-permeability membrane during construction, comprising:

[0032] S1: a groove 11 is formed on the base surface, and an adhesive 12 is filled into the groove 11 .

[0033] refer to Figure 3 As shown, in order to achieve the anti-seepage effect on the base surface and the isolation effect on the base surface, it is necessary to lay an anti-seepage membrane on the base surface. During the construction process of laying the anti-seepage membrane, a groove 11 must first be opened on the base surface. The groove 11 can be dug on the base surface by a grooving device or a grooving tool. The groove 11 is formed on the base surface in a concave form. Specifically, the opening position of the groove 11 can be roughly determined according to the width size of the anti-seepage membrane. The reason is that the opening of the groove 11 is used to accommodate and mix the adhesive 12 at the joint of the first anti-seepage membrane 20 and the second anti-seepage membrane 30. Therefore, the spacing distance or position of the groove 11 can be roughly set according to the width size of the first anti-seepage membrane 20 and the second anti-seepage membrane 30.

[0034] After the groove 11 is opened, the adhesive 12 is filled into the interior of the groove 11. The groove 11 is recessed on the base surface, and the adhesive 12 is filled at least to the top surface of the groove 11 in the height direction. The adhesive 12 is used to achieve bonding and fixing of the first anti-permeability membrane 20 and the second anti-permeability membrane 30. Specifically, the adhesive 12 is a gel-like material that can achieve bonding and fixing of the first anti-permeability membrane 20 and the second anti-permeability membrane 30.

[0035] S2: The outer edge of the first end of the first anti-permeability membrane 20 is immersed in the groove 11 and in contact with the adhesive 12. A plurality of first through holes 21 are arranged on one side of the first end of the first anti-permeability membrane 20. The plurality of first through holes 21 are arranged at intervals along the length direction of the first end of the first anti-permeability membrane 20. Part of the adhesive 12 flows from the groove 11 to the top surface of the first end of the first anti-permeability membrane 20 through the first through holes 21.

[0036] Specifically, refer to Figure 2 As shown, the outer edge of the first end of the first anti-permeability membrane 20 is inserted into the groove 11, so that the outer edge of the first anti-permeability membrane 20 and its first through hole 21 are in contact with the adhesive in the groove 11, and part of the adhesive can flow from the inside of the groove 11 to the surface of the first anti-permeability membrane 20 through the first through hole 21, thereby achieving the subsequent bonding of the first anti-permeability membrane 20 and the second anti-permeability membrane 30.

[0037] Specifically, the first through hole 21 is arranged in a straight line close to the first end of the first anti-permeability membrane 20 and away from the outer edge of the first end of the first anti-permeability membrane 20. The purpose of setting the first through hole 21 is to allow part of the adhesive 12 to mix and flow through the first through hole 21 to the surface of the first anti-permeability membrane 20.

[0038] refer to Figure 2 As shown, the straight-line distance L1 between the center of the first through hole 21 and the outer edge of one side of the first end of the first anti-permeability membrane 20 is in the range of 10mm-15mm, thereby ensuring that the adhesive 12 flowing out through the first through hole 21 can ensure the contact area with the second anti-permeability membrane 30 above it, thereby ensuring the connection stability between the first anti-permeability membrane 20 and the second anti-permeability membrane 30.

[0039] S3: The first end of the second anti-permeability membrane 30 is placed above the first end of the first anti-permeability membrane 20, and a plurality of second through holes 31 are arranged on one side of the first end of the first anti-permeability membrane 20. The plurality of second through holes 31 are arranged at intervals along the length direction of the first end of the second anti-permeability membrane 30. When the first end of the second anti-permeability membrane 30 is placed above the first end of the first anti-permeability membrane 20, the first through holes 21 and the second through holes 31 are arranged at intervals and staggered along the length direction of the first end of the first anti-permeability membrane 20.

[0040] Specifically, refer to Figure 2 As shown, the first end of the second anti-permeability membrane 30 is correspondingly placed above the first end of the first anti-permeability membrane 20 to achieve the subsequent bonding and laminating of the second anti-permeability membrane 30 and the first anti-permeability membrane 20. Specifically, the linear distance L2 between the center of the second through hole 31 and the outer edge of one side of the first end of the second anti-permeability membrane 30 is in the range of 10mm-15mm, so that the adhesive 12 has an effective functional connection area through the second through hole 31 and the first through hole 21, thereby ensuring the connection stability of the second anti-permeability membrane 30 and the first anti-permeability membrane 20.

[0041] Specifically, refer to Figure 2As shown, when the first end of the second anti-permeability membrane 30 is placed above the first end of the first anti-permeability membrane 20, the plurality of first through holes 21 and the plurality of second through holes 31 are arranged along the same straight line, thereby allowing part of the adhesive 12 to flow to the surface of the first anti-permeability membrane 20 through the first through holes 21, and part of the adhesive 12 to enter the surface of the second anti-permeability membrane 30 through the second through holes 31 to achieve subsequent bonding connection.

[0042] Specifically, the aperture size of the first through hole 21 is larger than the aperture size of the second through hole 31, thereby allowing part of the adhesive 12 to preferentially enter between the first anti-permeability membrane 20 and the second anti-permeability membrane 30 through the first through hole 21, and the adhesive 12 with less restriction through the second through hole 31 with a smaller spatial size flows through the second through hole 31 to the upper surface of the second anti-permeability membrane 30, thereby preventing a large amount of adhesive 12 from being discharged outward and affecting the connection stability.

[0043] Specifically, the spacing dimension between two adjacent first through holes 21 is greater than 2 times the aperture dimension of the second through hole 31. That is to say, the spacing dimension between two adjacent first through holes 21, i.e., the distance dimension between the centers of the two adjacent first through holes 21, is greater than 2 times the aperture dimension of the second through hole 31, thereby limiting the flow amount of bonding between the first and second anti-permeation membranes 20 and 30 through the positional relationship between the first and second through holes 21 and 31, ensuring the mixing of the adhesive and the dispersion stability between the first and second anti-permeation membranes 20 and 30, ensuring that the adhesive can be retained between the first and second anti-permeation membranes 20 and 30 and the second anti-permeation membrane 30 to achieve bonding between the first and second anti-permeation membranes 20 and 30, and preventing the existence of more adhesive 12 between the first and second anti-permeation membranes 20 and 30, resulting in the reduction of the two parts of the material and the stability of bonding.

[0044] S4: attaching the outer edge of the first end of the second anti-permeation membrane 30 to the upper side of the first end of the first anti-permeation membrane 20 , and heat-melting the outer edge of the first end of the second anti-permeation membrane 30 and the first end of the first anti-permeation membrane 20 .

[0045] Specifically, the outer edge of the first end of the second anti-permeation membrane 30 and the upper part of the first end of the first anti-permeation membrane 20 are heat-melted, and the heat-melting welding is to heat the outer edge of the first end of the second anti-permeation membrane 30 and the upper part of the first end of the first anti-permeation membrane 20 by using a hot melt device and realize the welding connection between the two. Thus, the connection between the second anti-permeation membrane 30 and the first anti-permeation membrane 20 is realized.

[0046] S5: The first end of the second anti-permeation membrane 30 is heat-fused to weld the second through hole 31 and the surface of the first end of the first anti-permeation membrane 20 along the length direction thereof.

[0047] Specifically, the connection stability of the second anti-permeability membrane 30 and the first anti-permeability membrane 20 is further achieved, and the adhesive flowing through the first through hole 21 and the second through hole 31 in the previous process is fully utilized to achieve the connection between the second anti-permeability membrane 30 and the first anti-permeability membrane 20, and the second anti-permeability membrane 30 is welded along the straight line direction of the setting direction of the second through hole 31, so that the part of the adhesive in and around the second through hole 31 can be used under the action of the hot melt welding equipment to achieve the second anti-permeability membrane 30 and the first anti-permeability membrane 20 in the second through hole 31. The first through hole 21 and the second through hole 31 are bonded and connected by an adhesive. Specifically, since the first through hole 21 and the second through hole 31 are staggered in a straight line direction, that is, there is no intersection or overlap between the first through hole 21 and the second through hole 31 in the height direction of the second anti-permeability membrane 30 and the first anti-permeability membrane 20 stacked, the surface of the first anti-permeability membrane 20 can be located below the second through hole 31, that is, the area between adjacent first through holes 21, so that the connection between the first anti-permeability membrane 20 and the second anti-permeability membrane 30 within the area can be achieved by an adhesive.

[0048] Specifically, after the outer edge of the first end of the second anti-permeability membrane 30 is heat-melted to the first end of the first anti-permeability membrane 20, after waiting for 3 minutes, the first end of the second anti-permeability membrane 30 is heat-melted to the surface of the second through hole 31 and the first end of the first anti-permeability membrane 20 along its length direction. The effect of waiting for 3 minutes is that after the heat-melting welding of the outer edge of the second anti-permeability membrane 30 is achieved, the heat generated in the heat-melting welding process can act on the adhesive, thereby achieving preheating of the adhesive, improving its internal flow and mixing performance, and after waiting for 3 minutes, achieving heat-melting welding processing along the straight line direction of the second through hole 31, thereby achieving local connection between the first anti-permeability membrane 20 and the second anti-permeability membrane 30 within the range of the second through hole 31.
