[0002] At present, the general method for basement waterproof construction is to set a concrete cushion and cement mortar on the plain soil layer, then paste asphalt waterproof coiled material, then set a concrete protective layer, and finally pour a waterproof reinforced concrete floor slab and a building surface layer. Through the double waterproofing of the asphalt waterproof coiled material and the waterproof reinforced concrete floor slab, however, in the traditional construction method, the waterproof coiled material is often pasted or laid empty on the base layer, and the gap between the waterproof layer and the structure body causes the separation of the waterproof layer and the structure. Once the waterproof layer is damaged, water flows around, and it is not easy to find the leakage point, and the repair is very difficult, and even may cause the overall failure of the waterproof layer. Summary of the Invention

[0006] By adopting the above technical solutions, an auxiliary waterproof layer is provided between the additional waterproof layer and the internal corner detail. By using the matching structure of the grouting hole on the auxiliary waterproof layer and the groove on the base layer, the filling space of the cement mortar is fixed, so that the filling amount of the cement mortar is easier to control and the construction difficulty is reduced, avoiding the situation that the cement mortar is laid unevenly, the additional waterproof layer is skew, wrinkled or even bulged after being pasted; at the same time, a section of waterproof coiled material is accommodated inside the first inner cavity of the first positioning groove, which has a certain positioning effect on the waterproof coiled material, and can prevent the waterproof coiled material from being deformed, misaligned, wrinkled, etc. caused by workers walking on the waterproof coiled material or dragging building materials during construction. The reserved expansion space enables the waterproof coiled material to have higher adaptability to the expansion or cracking deformation of the building layer. Compared with traditional gluing, the waterproof coiled material can be leveled after being pasted, avoiding wrinkles and bulges. At the same time, the detachable structure makes the waterproof coiled material easier to adjust, improving the constructability.

[0007] Preferably, the upper surface of the waterproof coiled material is provided with an upper adhesive surface, the upper adhesive surface is provided with a separation layer, and a first easy tear line is provided at a position of the separation layer close to the first positioning groove.

[0008] By adopting the above technical solution, an upper adhesive surface is arranged on the upper surface of the waterproof coiled material, so that the waterproof coiled material is integrated with the upper cast-in-place concrete surface, avoiding the hidden danger of water seepage in the middle. At the same time, due to the arrangement of the first easy tear line, the separation layer can be reserved during construction and then torn off according to the construction situation.

[0014] By adopting the above technical solution, the anti-adhesive layer is composed of an adhesive film and a bottom layer, and the puncture-resistant layer is adhesively bonded to the upper surface of the bottom layer. The puncture-resistant layer can reduce the damage to the waterproof coiled material that is easily caused due to the lack of a protective layer during construction.

[0015] Preferably, the waterproof coiled material at least includes a first waterproof coiled material sheet and a second waterproof coiled material sheet. An overlapping lapping portion is arranged between the first waterproof coiled material sheet and the second waterproof coiled material sheet. A second positioning groove is arranged in the base layer below the lapping portion, a second positioning strip is arranged in the second positioning groove, the second positioning strip is provided with a second inner cavity, and the space of the second inner cavity is larger than that of the first inner cavity.

[0018] By adopting the above technical solution, the annular auxiliary waterproof layer can be directly sleeved on the pile head for waterproofing the pile head internal corner.

[0019] Preferably, a third positioning groove is provided between two adjacent first positioning grooves.

[0020] By adopting the above technical solution, the cooperation of the first positioning groove and the third positioning groove strengthens the positioning of the waterproof coiled material.

[0021] Preferably, the first positioning strip is a magnetic metal strip.

[0022] By adopting the above technical solution, the magnetic metal strip cooperates with the magnet, which can be used to determine the position of the positioning groove, facilitating the subsequent pressing of the waterproof coiled material into the positioning strip.

[0026] Prepare waterproof coating: Use polymer emulsion and cement as the main raw materials, and add additives to make a water-based building waterproof coating.

[0027] Snap the reference line: According to the paving direction of the waterproof coiled material, snap the control line of the waterproof coiled material on the base, and lay the waterproof coiled material from low to high along the water flow direction.

[0029] Coiled material paving: When paving the vertical coiled material, use a connecting block and a pull rope to connect and fix the upper part of the coiled material to the wall or the set bracket on the upper adhesive surface of the coiled material close to the wall; use a soft rubber plate or roller to scrape and press from the middle to the other side of the coiled material lap direction to discharge the air, so that the coiled material is fully adhered to the base surface; when lapping and paving the next coiled material, lift the release paper at the lap part of the coiled material located at the lower layer, align the upper coiled material with the lap control line and paste it flat on the lower coiled material, scrape and press to discharge the air, and fully adhere.

[0030] When laying flat coiled materials, after placing the first positioning strip in the first positioning groove, first cut the coiled materials to be laid, and lay the single-sided reaction adhesive waterproof coiled material with the adhesive side facing up on the base surface; then use a rolling equipment to press the waterproof coiled material above the first positioning groove into the first positioning groove and heat-press a first easy-to-tear line near the first positioning groove; after tying the steel bars, gradually peel off the release paper of the coiled material at the corresponding part.

[0031] Lap sealing: Tear off the release film at the lap of the upper and lower coiled materials, scrape and apply neat cement slurry at the lap edge and lap them together, directly seal the end with neat cement slurry, the lap widths of the long side and the short side are both not less than 100 mm, and finally level and seal with neat cement slurry.

[0032] By adopting the above technical solutions, the reaction adhesive polymer waterproof coiled material is used, the non-bonding surface is laid empty on the foundation cushion layer, the bonding surface faces upward and is combined with the cast-in-place concrete surface as a whole, and there is no hidden danger of water channeling in the middle; even if the coiled material is locally damaged, the water will be limited within a very small range, greatly improving the reliability of the waterproof layer. At the same time, with the setting of the auxiliary waterproof layer and the positioning groove, the construction is more convenient, the position of the waterproof coiled material after pre-laying is more fixed, and it is not easy to be misaligned to generate leakage joints, ensuring the waterproof construction quality.
