Deformation joint waterproof structure and method
The invention discloses a deformation joint waterproof structure and method, and belongs to the technical field of building waterproofing, the deformation joint waterproof structure comprises a first concrete plate and a second concrete plate, when the first concrete plate and the second concrete plate are poured, an XPS template of not less than 45 kg/m<3> is pre-buried at a deformation joint, and the deformation joint is formed between the first concrete plate and the second concrete plate; an M-shaped rubber and plastic foam water-stop belt is arranged in the deformation joint, the lower portion of the M-shaped rubber and plastic foam water-stop belt is made to be tightly attached to the pre-buried XPS template, and the two sides of the M-shaped rubber and plastic foam water-stop belt are fixedly bonded to the side wall of the deformation joint through a waterproof adhesive; after the adhesive reaches the strength, the M-shaped rubber and plastic foam water stop belt is covered with a high-density polyethylene protection plate so as to protect the water stop belt; and a channel steel gland which is as long as the deformation joint is arranged on a roulette on the high-density polyethylene protection plate, and the two sides of the channel steel gland are anchored in a sliding mode through anti-pulling anchor bolts. Chemical sealing is adopted for anti-seepage sealing, perforation channel steel is adopted for resisting hydrostatic pressure, angle steel anchoring is additionally arranged on the two sides, and the chemical sealing and the perforation channel steel are combined to form a sealing compression-resistant structure.
本发明公开了一种变形缝防水构造和方法，属于建筑防水技术领域，包含：第一砼板和第二砼板，第一砼板和第二砼板浇筑时在变形缝处预埋不小于45kg/m3之XPS模板，第一砼板和第二砼板之间形成变形缝；在变形缝内设置M形橡塑泡沫止水带，使M形橡塑泡沫止水带的下方紧贴预埋的XPS模板，M形橡塑泡沫止水带的两侧通过耐水粘合剂与变形缝的侧壁粘固；粘合剂达到强度之后在所述M形橡塑泡沫止水带的上方覆盖高密度聚乙烯保护板以保护止水带；高密度聚乙烯保护板之上骑缝设置与变形缝通长的槽钢压盖，并在所述槽钢压盖的两侧以抗拔锚栓可滑移锚固。本发明防渗密封采用化学密封，抵抗静水压选用骑缝槽钢，两侧加设角钢锚固，二者结合形成密封抗压构造。
