Waterproof construction method for precast pile head
The invention relates to the technical field of building construction, in particular to a precast pile head waterproof construction method which comprises precast pile foundation construction and peripheral concrete cushion construction. A reinforcement cage is placed in a pile core of the precast pile foundation, and pile core concrete is poured to the position 200 mm below the pile top elevation; after pile core concrete is finally set, cement-based permeable crystals are brushed, and after the cement-based permeable crystals are dried, water-swelling water stopping strips are placed around the pile core; pile core concrete is poured to the pile top elevation; after pile core concrete is finally set, the pile top, the pile side and the pile periphery are coated with cement-based permeable crystals; after the cement-based permeable crystals are dried, non-cured rubber asphalt is coated in a blade mode, a waterproof coiled material is pasted, and after the waterproof coiled material is laid, the reinforcing steel bars are sleeved with water-swelling water stop rings. Effective waterproof treatment is carried out on the precast pile core and the pile head, the effectiveness of a flexible waterproof system is guaranteed, and the hidden danger of basement leakage is reduced.
本发明涉及建筑施工技术领域，具体为一种预制桩桩头防水施工方法，预制桩基础施工及周边混凝土垫层施工；预制桩基础的桩芯放置钢筋笼，浇筑桩芯混凝土至桩顶标高下200mm；桩芯混凝土终凝后涂刷水泥基渗透结晶，水泥基渗透结晶干燥后沿桩芯周围放置遇水膨胀止水条；浇筑桩芯混凝土至桩顶标高；桩芯混凝土终凝后在桩顶、桩侧和桩周边涂刷水泥基渗透结晶；水泥基渗透结晶干燥后刮涂非固化橡胶沥青并粘贴防水卷材，防水卷材铺贴完成后在钢筋处套入遇水膨胀止水环即可。本发明对预制桩桩芯和桩头有效防水处理，保证柔性防水系统的有效性，减小地下室渗漏隐患。
