Pile cap waterproof structure and construction method
The invention belongs to the technical field of building construction, and particularly relates to a pile cap waterproof structure and a construction method.The waterproof structure comprises a concrete cushion layer, and a modified asphalt waterproof coiled material layer is laid on the concrete cushion layer; the modified asphalt waterproof coiled material layer is provided with a bottleneck-shaped closing opening at the bottom of the pile head of the cast-in-place pile; an annular formwork is arranged on the periphery of the bottom of a pile head of the cast-in-place pile, and non-cured asphalt factice is poured into the annular formwork. The method has the advantages that the non-cured asphalt factice is used for conducting waterproof sealing on the closing opening, and the non-cured asphalt factice is poured into the annular formwork; according to the method, the situation that non-curing asphalt factice is directly smeared on the closing opening, so that the non-curing asphalt factice possibly exists or is missed to be smeared is avoided, the non-curing asphalt factice can be evenly made to make contact with the pile head, a gap between the modified asphalt waterproof coiled material and the pile head is effectively blocked, deformation at the closing opening can be resisted to a certain degree, and the service life of the pile head is prolonged. And possible water leakage at the closing position caused by overhigh water pressure at a certain position of the pile head is avoided.
本发明属于建筑施工技术领域，具体涉及一种桩承台防水构造和施工方法，防水构造包括混凝土垫层，混凝土垫层上方铺贴改性沥青防水卷材层；改性沥青防水卷材层在灌注桩的桩头底部处存在瓶颈形的收口；灌注桩的桩头底部外周围有环形模板，环形模板内灌注有非固化沥青油膏；本发明的优点和积极效果在于：采用非固化沥青油膏对收口进行防水密封，而且将非固化沥青油膏灌注到环形模板内；避免了直接在收口涂抹非固化沥青油膏可能存在的涂抹不均匀或漏涂的情况，可以均匀地使非固化沥青油膏与桩头接触，有效地将改性沥青防水卷材与桩头之间的缝隙封堵住，且能够抵抗一定程度的收口处形变，避免因桩头某处水压过大，导致可能出现的收口处漏水。
