Connected to the upper end of the concrete cushion 2, the concrete waterproof protective layer 4 is laid on the upper end of the asphalt membrane 3, the lower end of the anchor rod anchoring steel bar 5 passes through the concrete waterproof protection layer 4, the asphalt membrane 3 and the concrete cushion 2 in turn, and is inserted into the self-base In the rock 1, the lower end of the grouting pipe 6 extends from the bedrock 1, the asphalt caulking grease 7 is fixed on the annular side of the bolt anchoring steel bar 5, and the water stop strip 9 is wound around the annular side of the bolt anchoring steel bar 5, and is arranged on the On the lower side of the asphalt caulking paste 7, the temporary reinforcement system 10 is bundled on the anchor rod anchoring reinforcement 5, and the loose soil, stones and sundries in the pouring cushion part are cleaned up. When the concrete cushion layer is 2, make a control line to ensure that the thickness of the concrete layer should not be less than 100mm, and use ordinary shale bricks for the enclosure at the 5 nodes of the anti-floating bolt anchoring steel bar. The diameter of the enclosure is 500mm to prevent the cushion concrete from flowing. In the shortlisted block, after the concrete cushion layer 2 is poured, the shale bricks surrounded by the 5 anti-floating anchor rod anchoring steel bars shall be cleaned. The slurry on the anchor rod 5 is shaved. The size of the chisel is 500mm for the upper port, 200mm for the bottom port, and 400mm for the height. After shaving and chiseling, clean the upper sand and gravel of the cushion in time, and the anchor rod anchors the 5 nodes of the steel rod. After the sand, gravel and slurry are cleaned according to the requirements, the pre-processed iron cup groove mold is inserted along the top of the anchor rod anchoring steel bar 5 into the anchor rod anchorage steel bar 5 node, and the iron cup groove mold is made of C15 concrete. Fill the gap between the outer side and the gravel. After the concrete reaches the strength, take out the mold. After the iron cup groove mold is taken out, use cement mortar to smooth out the unevenness inside the cup groove. Check whether the bottom of the cup groove is leveled. The water-swelling water-stop strip 9 is tightly wound on the anti-floating anchor rod anchoring steel bar 5, and the winding height is greater than 100mm, and finally the water-stopping strip 9 is fixed with cement nails. After the water stop strip 9 is wound, the building waterproof asphalt caulking ointment 7 should be poured between the BW water-swelling water stop strip 9 and the anchor rod anchoring steel bar 5 immediately. Fill the BW water-swellable water-stop strip 9 tightly without leaving any gaps. After the first time of building waterproof asphalt caulking ointment 7 is poured for 10 minutes, the second time of asphalt caulking ointment 7 is poured to ensure that the BW meets the requirements. The compactness between the water-swelling water stop strip 9 and the anchoring steel bar 5, the 5 nodes of the anchoring steel bar at the top of the construction cup groove are sealed with ointment, and the sealing height of the ointment is 100mm. 5 After the waterproof construction at the node is completed, the cup groove should be sealed with C15 concrete immediately. , After the cup-shaped groove concrete is closed, the upper mouth of the cup-shaped groove should be polished with concrete raw slurry immediately. When SBS modified bitumen waterproof coating is used, the anti-floating anchor anchoring steel bar 5 is the center, and the radius is greater than 550mm. The thickness of the coating is 1.5mm thick. When it is uneven or the pit is large, use 1:2.5 cement mortar to smooth it. The corners such as the inner corners and other inner and outer corners connected to the base layer and the pipeline should be plastered into uniform, flat and smooth rounded corners, and the radius of the arc should not be less than 50mm, the yin and yang corners, pipe roots and other complex parts must be cleaned carefully and carefully. If there are oil stains, rust, etc., they should be cleaned with sandpaper, wire brushes, solvents, etc., and foreign objects protruding from the surface of the base must be removed. Sand and mortar lumps, etc. Remove, use high-pressure air to clean up the dust and debris, and when the moisture content of the base layer is below 9%, apply two coats of cold base oil to the base layer treatment agent. The next process can be carried out after the feet. For the yin and yang corners, construction joints and other parts, before laying the coil, do reinforcement treatment, the paste must be firm, the yin and yang corners are firmly glued with additional coils, and the waterproof layer of the coil is added at the corners. One layer, each side ≥ 250mm, when laying, the coil can be laid naturally without wrinkles, without tension, so as not to affect the quality of the additional layer, the distance between the flame nozzle and the coil is moderately controlled, and the width is heated within the width. Evenly, the surface of the coil is melted to bright black, and the coil is not heated too much. After the surface of the coil is hot-melted, the construction personnel should immediately roll the coil. When rolling, the air under the coil should be removed to make it flat and smooth. The sticking is firm, and the coils are overlapped with each other by 100mm to meet the requirements of waterproof specifications. When laying the coils, it should be flat and straight, the overlap size is accurate, and not twisted. The coil should be cut in a straight line, and a small triangular gap should be cut around the anchoring steel bar 5 for hot-melt paving. After the coil layer is paved, add a coil reinforcement layer 8 on the upper part of the coil, and finally pour it. 50mm thick C20 fine stone concrete protective layer, when pouring concrete, do not damage the plane of the membrane waterproof layer, use the characteristics of various waterproof materials, in the order of the anchor rods in the concrete cup grooves that have been constructed Anchor steel bars 5 Wind the BW water-swellable water-stop strip 9 on top, pour the building asphalt caulking ointment 7, seal the cup-shaped groove with concrete and apply the water-emulsion SBS waterproof coating on the concrete surface, and finally pave a large area with 4mm thick waterproof membrane , Overlap construction of various waterproof materials, so that the characteristics of various waterproof materials are optimal in the construction, avoiding the leakage phenomenon of the anti-floating anchor rod anchoring steel bar 5 and the concrete at the node due to the occurrence and development of the capillary channel phenomenon, Ensure that the waterproofing of the 5 nodes of the anchoring steel bar achieves the effect of combining internal and external and complementing each other, so that the waterproof quality of the 5 nodes of the anchoring steel bar meets the requirements of the construction specification. Finally, the anchoring steel bar 5 is bent and bent by a portable hydraulic bending machine. The folding angle is 90°, and the anchor rod is clamped between the anchoring steel bars 5 The angle is 120°, and then the steel bar 7 with a diameter of C12 or C14 is bound at the horizontal part of the anchoring steel bar 5 after bending, and is arranged in one direction, and part of the main bar acts as a temporary support for the horizontal structure, forming a complete temporary support system Therefore, it is convenient to use. By bending the projecting part of the anchoring steel bar 5, the steel material is saved, the material cost and construction time are reduced, and it is also conducive to green construction and has a good waterproof effect.
止水条9为BW遇水膨胀止水条，缠绕高度大于100mm，并用水泥钉固定牢固。The water stop strip 9 is a BW water-swellable water stop strip, the winding height is greater than 100mm, and it is firmly fixed with cement nails.
沥青卷材3为4mm厚SBS聚酯胎 -25°Ⅱ型改性沥青卷材，且沥青卷材3上端铺设卷材加强层8。The asphalt coil 3 is a 4mm thick SBS polyester tire -25° type II modified asphalt coil, and a coil reinforcement layer 8 is laid on the upper end of the asphalt coil 3 .
