Description

Technical Field

[0001] The utility model relates to the technical field of housing building waterproof construction, in particular to a basement side wall waterproof structure. Background Art

[0002] Currently, there are two common approaches to waterproofing basement side walls: one is the combined use of non-curing asphalt coating and asphalt-based membranes; the other is the direct dry application of self-adhesive polymer waterproofing membranes. Both approaches have their drawbacks. In the summer, the surface temperature of the side walls can reach as high as 80°C, and the tensile stress of non-curing asphalt coatings is very low, making the membranes laid on top prone to slippage. Furthermore, the chemical and construction processes of non-curing asphalt coatings generate large amounts of fumes, which pollute the environment. The base of the side walls often suffers from quality defects such as dust, sand, and roughness, making it difficult to ensure adhesion when dry-applying self-adhesive polymer waterproofing membranes. Consequently, there is currently no optimal waterproofing solution for basement side walls.

[0003] With the implementation of the "General Specification for Waterproofing of Buildings and Municipal Engineering," it is clearly required that open-cut underground projects have at least two waterproof layers. Currently, a single waterproof layer structure can no longer meet the basic requirements of first-level waterproofing. To prevent water leakage between the two waterproof layers, the waterproof layers must be effectively bonded together. To ensure the durability of the waterproof layers, the materials of the two waterproof layers must also be compatible. Therefore, a reasonable, new waterproof structure is urgently needed to address the waterproofing issues of basement side walls under the new regulations. Utility Model Content

[0004] The purpose of the present invention is to provide a waterproof structure for basement side walls in order to address the deficiencies in the prior art.

[0005] The utility model provides a waterproof structure for basement side walls, which adopts the following technical solutions:

[0006] A basement side wall waterproof structure, characterized by comprising a side wall structure layer, a base treatment agent layer, an anti-slip waterproof coating layer and a self-adhesive polymer waterproof membrane layer stacked in sequence from the inside to the outside;

[0007] Preferably, the base treatment agent layer is any one of acrylic polymer emulsion, styrene acrylic polymer emulsion, and cement floor hardener.

[0008] Preferably, the anti-slip waterproof coating layer is any one of a high-viscosity anti-slip non-asphalt-based non-curing waterproof coating, a high-viscosity anti-water-skidding asphalt-based waterproof coating, a cement-based waterproof coating, and a cement-based waterproof material.

[0009] Preferably, the self-adhesive polymer waterproof roll material layer includes a polymer base material layer and a self-adhesive layer, and the self-adhesive layer is located between the polymer base material layer and the anti-slip waterproof coating layer.

[0010] Preferably, the anti-skid waterproof coating layer is a high-viscosity anti-skid non-asphalt-based non-curing waterproof coating, the self-adhesive layer is a non-asphalt-based self-adhesive layer, selected from any one of pressure-sensitive adhesive or butyl adhesive, the self-adhesive polymer waterproof roll layer is a non-asphalt-based waterproof roll, and the polymer substrate layer is any one of HDPE sheet layer, TPO sheet layer, TPR sheet layer, PVC sheet layer, PET film layer, strong cross film layer or fluorocarbon film layer; the anti-skid waterproof coating layer is a high-viscosity anti-skid In the case of an asphalt-based waterproof coating, the self-adhesive layer is an asphalt-based self-adhesive layer, the self-adhesive polymer waterproof roll layer is an asphalt-based waterproof roll, and the polymer substrate layer is any one of a PET film layer, a strong cross film layer, a polyester non-woven fabric layer or a fluorocarbon film layer; in the case of an anti-slip waterproof coating layer being a cement-based waterproof coating or a cement-based waterproof material, the self-adhesive layer is any one of a non-asphalt-based self-adhesive layer or an asphalt-based self-adhesive layer, and the polymer substrate layer is consistent with the above two cases.

[0011] Furthermore, the waterproof structure is characterized in that the amount of the base treatment agent is 50-300g / m 2 ;

[0012] When the anti-slip waterproof coating layer is selected from a high-viscosity anti-slip non-asphalt-based non-curing waterproof coating, a high-viscosity anti-water-skidding asphalt-based waterproof coating or a cement-based waterproof coating, its thickness is 1.5-3.0 mm; when selected from a cement-based waterproof material, its thickness is 6-18 mm;

[0013] The thickness of the self-adhesive polymer waterproof membrane is 1.2-4.0 mm, the thickness of the self-adhesive layer is 0.3-2.0 mm, and the thickness of the polymer substrate layer is 0.05-2.0 mm.

[0014] Furthermore, the construction method of the basement side wall waterproof structure includes the following steps:

[0015] Step 1: Clean the base: remove foreign objects, mortar lumps and other dust and debris protruding from the surface of the base of the basement side wall. Conduct concealed engineering inspection and acceptance of wall-penetrating pipes, expansion joints, etc.

[0016] Step 2: Apply the base treatment agent on the side wall structure layer: The base treatment agent should be fully stirred before use, and should be applied evenly without any leakage or bottom exposure, and without accumulation or flow. The next step can be carried out only after the application is completed and the coating is dry.

Apply or spray anti-skid waterproof coating on the base treatment agent layer: When using high-viscosity anti-skid non-asphalt-based non-curing waterproof coating, the coating should be heated to 130-160°C, applied or sprayed onto the base surface, and applied or sprayed multiple times to the required thickness; when using high-viscosity anti-skid asphalt-based waterproof coating, cement-based waterproof coating or cement-based waterproof material, it should be fully stirred or the powder and liquid should be mixed evenly in proportion and then applied or sprayed onto the base surface, and applied or sprayed multiple times to the required thickness, with each layer being about 0.5mm thick. After the previous coating is cured, apply or spray the next layer of coating on its surface. The scraping or spraying method is the same as the first layer, and the scraping or spraying direction must be perpendicular to the direction of the previous layer. After the anti-skid waterproof coating layer is dry and passed the acceptance inspection, the next process can be carried out;

[0018] Step 4: Lay self-adhesive polymer waterproofing membrane over the anti-slip waterproof coating: First, lay an additional layer of membrane in detailed structural areas, such as the intersection of side walls and facades, through-wall pipes, and horizontal construction joints, and then lay the larger membrane. The long edges of the membrane should be overlapped using hot air welding or self-adhesive bonding.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) By setting a base treatment agent layer on the side wall of the basement, the base treatment agent forms a thin film after drying, which can block the capillary pores in the concrete and harden the floating sand of the base layer to achieve the purpose of surface cleaning and surface hardening, thereby improving the bonding strength between the wall and the waterproof layer.

[0021] (2) By setting an anti-slip waterproof coating layer on the side wall of the basement, taking advantage of its high bonding strength with the base layer, strong resistance to vertical slippage, simple and environmentally friendly construction, after it is compounded with the self-adhesive polymer waterproof membrane, the two waterproof layers are fully bonded, so that the overall waterproof layer does not slip, and the overlapping parts of the waterproof membrane will not come off. The full bonding effect prevents water leakage and improves the reliability of the waterproof system.

[0022] (3) The two waterproof layer structures composed of the anti-slip waterproof coating layer and the self-adhesive polymer waterproof membrane follow the compatibility principle. The durability of the polymer base material is guaranteed, meeting the requirements of the first-level waterproofing for underground areas in the "General Specifications for Waterproofing of Buildings and Municipal Engineering", and ensuring the waterproof quality.
