Description

Technical Field

[0001] The utility model belongs to the field of basement waterproofing, and more specifically, relates to a non-tear-film type waterproofing coiled material composite pre-laid waterproofing system. Background Art

[0002] With the fierce development and construction of cities and the scarcity of land resources, civil buildings, industrial buildings and integrated pipelines are all extended underground. However, basement waterproofing has always been a problem of waterproofing. After the building is built, it is difficult to repair it after leakage occurs, and the normal use of the basement cannot be guaranteed. There are many choices for waterproofing solutions for underground leakage. The most widely used solution is to use SBS modified asphalt waterproof membrane. In response to the current serious leakage situation, the waterproofing industry has also made further improvements and adopted the pre-laid reverse bonding method for construction.

[0003] The pre-laid reverse-adhesive method is to first lay the pre-laid reverse-adhesive waterproofing membrane in the construction project, and then pour concrete on the surface of the membrane, so that the membrane and the solidified post-cast concrete structure form a tightly attached and bonded bonding effect. The selection of materials can be divided into three types according to the standard of GB / T23457-2017 "Pre-laid Waterproofing Membrane", namely plastic (P), polyester tire modified asphalt (PY), and rubber (R). Before 2023, according to the requirements of GB 50108-2008 "Technical Specifications for Waterproofing of Underground Engineering", when the baseboard waterproofing is level one and the pre-laid reverse-adhesive method is used for construction, a 1.2mm thick high-density polyethylene self-adhesive film HDPE can meet the waterproofing requirements. The waterproofing effect of the pre-laid reverse-adhesive method has been improved, but it is not ideal, so there are still certain disadvantages as a single-channel waterproofing implementation.

[0004] According to the "General Specifications for Waterproofing of Buildings and Municipal Engineering" implemented on April 1, 2023, when the basement waterproofing is level one, a single layer of 1.2mm thick HDPE cannot meet the requirements, and an additional layer of other compatible waterproof materials is required.

[0005] At present, the combination of basement floor waterproofing methods is mostly conventional SBS combination scheme, that is, SBS and modified asphalt self-adhesive membrane combination scheme, and this combination scheme is easy for customers to accept. The method has been used for many years and is mature and stable, but it has the following disadvantages:

[0006] ① The waterproof layer and the base layer need to be fully bonded, which is labor-intensive and material-intensive;

[0007] ②It is necessary to design an isolation layer and a protective layer, which takes a long time to complete;

[0008] ③ The overall approach is relatively costly and has the potential for water leakage, which cannot be cured after leakage in the later stage;

[0009] Therefore, most basements are currently using the pre-paved anti-adhesive construction process. According to the new strong requirements, whether it is a polymer pre-paved anti-adhesive material or an asphalt pre-paved anti-adhesive material, two layers are required. The polymer pre-paved anti-adhesive product has a high cost-effectiveness. Its material is plastic or rubber. It can be buried underground for a hundred years without rotting. It can meet the same lifespan requirements as the building and can also ensure the waterproof effect. However, according to the current market situation, in order to ensure its construction convenience and meet the requirements of material compatibility, adhesive-backed polymer waterproofing membranes are used. During actual construction, the isolation film on the back can be torn off for construction. It meets the normal construction techniques of workers and solves the problem of material incompatibility when using membranes of different materials. It solves the waterproofing problem to a certain extent. At the same time, when asphalt membranes are combined with polymer pre-paved waterproof membranes, the advantages and disadvantages can be complementary. To maximize the waterproof effect of the waterproof system. The waterproof combination scheme is as follows:

[0010] ①Polymer pre-laid waterproofing membrane (adhesive type) + tireless self-adhesive modified asphalt waterproofing membrane;

[0011] ②Polymer pre-laid waterproofing membrane (adhesive type) + SBS modified asphalt waterproofing membrane;

[0012] The above two solutions can meet the requirements of strong bars and on-site construction, but have the following disadvantages:

[0013] (1) When compounded with SBS modified asphalt waterproofing membrane, the isolation film on the surface of SBS modified asphalt waterproofing membrane is PE film, and the peeling strength with the adhesive-backed polymer pre-laid waterproofing membrane is slightly lower. The experimental data are shown in Table 1:

[0014] Table 1

[0015]

[0016]

[0017] Note: The two values ​​before and after the peel strength represent the maximum peel value and the average peel value respectively.

[0018] (2) When compounded with tireless self-adhesive modified asphalt waterproofing membrane, the tireless self-adhesive modified asphalt waterproofing membrane is a tireless membrane. In actual construction, the first membrane of the base plate (tireless self-adhesive modified asphalt waterproofing membrane) needs to be laid empty, but the base layer often fails to meet the ideal flatness requirements, which will cause the risk of being broken;

[0019] (3) When compounded with tireless self-adhesive modified asphalt waterproofing membrane, the tireless self-adhesive modified asphalt waterproofing membrane is a tireless membrane, so the tension and the risk of resistance to damage become greater;

[0020] (4) When compounding with the tireless self-adhesive modified asphalt waterproof membrane, when the self-adhesive surface of the tireless self-adhesive modified asphalt waterproof membrane faces upward and the isolation film of the tireless self-adhesive modified asphalt waterproof membrane is not torn off, the tireless self-adhesive modified asphalt waterproof membrane and the polymer pre-laid waterproof membrane cannot be completely compounded, resulting in the risk of water leakage between the membrane layers.

[0021] Therefore, a new waterproof system is urgently needed to be proposed. Utility Model Content

[0022] The purpose of the utility model is to address the deficiencies of the prior art and propose a non-tearable waterproof membrane composite pre-laid waterproof system. After the non-tearable fiber-reinforced polymer membrane composite waterproof membrane layer and the adhesive-backed polymer pre-laid waterproof membrane layer are bonded together, water leakage between the membrane layers is not likely to occur, and the utility model can be applied to basement waterproofing.

[0023] In order to achieve the above-mentioned purpose, the utility model provides a non-tearing type waterproofing membrane composite pre-laid waterproofing system, the system comprises a plain soil ramming layer, a concrete cushion layer, a non-tearing type fiber-reinforced polymer membrane composite waterproofing membrane layer, a back-adhesive polymer pre-laid waterproofing membrane layer and a reinforced concrete bottom plate layer arranged in sequence from bottom to top;

[0024] The non-tearing fiber-reinforced polymer film composite waterproof coiled material layer is a multi-layer structure, and the upper surface layer of the non-tearing fiber-reinforced polymer film composite waterproof coiled material layer is a non-tearing polymer film layer.

[0025] Preferably, the non-tearable fiber-reinforced polymer film composite waterproof coiled material layer is obtained by extrusion compounding.

[0026] Preferably, the non-tear polymer film layer is made of PE cross-laminated film or PET film.

[0027] Preferably, the non-tearable fiber-reinforced polymer film composite waterproof roll material layer and the adhesive-backed polymer pre-laid waterproof roll material layer are fully adhered.

[0028] Preferably, the non-tear polymer film layer of the non-tear film type fiber-reinforced polymer film composite waterproof coiled material layer is fully adhered to the adhesive surface of the adhesive type polymer pre-laid waterproof coiled material layer.

[0029] Preferably, the reaction bonding surface of the adhesive-backed polymer pre-laid waterproof membrane layer is bonded to the reinforced concrete base plate layer.

[0030] Preferably, the lower surface layer of the non-tearable fiber-reinforced polymer film composite waterproof coiled material layer is a fiber-reinforced layer.

[0031] Preferably, the fiber reinforcement layer is made of non-woven fabric.

[0032] Preferably, the non-tearable fiber-reinforced polymer film composite waterproof coiled material layer comprises a fiber-reinforced layer, a lower self-adhesive asphalt layer, a middle polymer film layer, an upper self-adhesive asphalt layer and a non-tearable polymer film layer arranged in sequence from bottom to top.

[0033] Preferably, the material of the intermediate polymer film layer is PE cross-laminated film or PET film.

[0034] The beneficial effects of the technical solution of the utility model are as follows:

[0035] The non-tearable polymer film layer (made of PE cross-laminated film or PET film) of the non-tearable fiber-reinforced polymer film composite waterproof roll layer of the utility model is a film layer composited on the non-tearable fiber-reinforced polymer film-based waterproof roll, and is not a tearable isolation film, which is different from the isolation film on the surface of the existing waterproof roll that can be easily torn off. Therefore, after the non-tearable fiber-reinforced polymer film composite waterproof roll layer of the utility model is bonded with the adhesive-backed polymer pre-laid waterproof roll layer, it is not easy to cause water leakage between the roll layers, and can be used for basement waterproofing;

[0036] The non-tear film type fiber-reinforced polymer film composite waterproofing roll layer of the utility model is made of a PE cross-laminated film or a PET film. Therefore, the peeling strength between the non-tear film type fiber-reinforced polymer film composite waterproofing roll layer of the utility model and the adhesive-backed polymer pre-laid waterproofing roll layer is improved;

[0037] When the non-tearable fiber-reinforced polymer film composite waterproofing coiled material layer of the utility model is laid on an empty bottom plate, the fiber reinforcement layer of the non-tearable fiber-reinforced polymer film composite waterproofing coiled material layer can ensure the non-tearable fiber-reinforced polymer film composite waterproofing coiled material layer has the advantages of being resistant to rubbing and tensile strength;

[0038] The utility model adopts adhesive-backed polymer pre-laid waterproofing coiled material, which can ensure compatibility with non-tearable fiber-reinforced polymer film composite waterproofing coiled material when pasted;

[0039] The adhesive-backed polymer pre-laid waterproofing membrane and the non-tearable fiber-reinforced polymer film composite waterproofing membrane of the utility model are fully bonded, thereby retaining the working principle of the pre-laid reverse-adhesive system, while improving the durability of the entire waterproofing system, and making the mechanical properties between the membranes complementary, thereby improving the reliability of the waterproofing system.
