Construction method for pile head secondary forming waterproof construction
The invention discloses a construction method for pile head secondary forming waterproof construction, and relates to the technical field of waterproof construction of a cast-in-place concrete pile head. The construction method comprises the steps of breaking a pile head; assembling a pile head secondary forming tool type mold; arranging the mold; carrying out pile head secondary forming and cushion layer concrete pouring; dismantling the mold; arranging expansion water stop strips; sealing waterproof mortar; carrying out bottom plate waterproof construction; brushing cement-based capillary crystallization on to the pile head; and arranging pile head exposed steel bars and a plastic sleeve factice crack pouring tool type mold and the like. One pile head secondary forming tool type mold andthe plastic factice crack pouring tool type mold are designed in a targeted mode, through the implantation of the technical scheme, the technical problem that the leakage risk exists at waterproof cross positions between the pile head and a bottom plate can be effectively solved, so that the leakage risk and hidden danger existing in pile head waterproof construction are prevented, the secondaryrepairing cost caused by leakage of the waterproof pile head is reduced, resources are saved, and the secondary forming construction efficiency of the pile head and the waterproof construction qualityof the pile head are improved.
本发明公开了一种用于桩头二次成型防水施工的施工方法，涉及混凝土灌注桩桩头防水施工技术领域；该施工方法包括以下步骤：桩头破除‑桩头二次成型工具式模具拼装‑模具安装‑桩头二次成型及垫层砼浇筑‑拆除模具‑安装膨胀止水条‑防水砂浆封闭‑底板防水施工‑桩头涂刷水泥基渗透结晶‑安装桩头外露钢筋塑料套管油膏灌缝工具式模具等，由此针对性设计了一套桩头二次成型工具式模具、塑料油膏灌缝工具式模具，通过实施本技术方案，可有效解决桩头与底板防水交叉位置存在渗漏风险的技术问题，防止桩头防水施工存在的渗漏风险和隐患，减少了桩头防水因渗漏而产生二次修补费用，节约了资源，提高了桩头二次成型施工工效与桩头防水施工质量。
