The invention discloses a cast-in-place pile head, relates to the technical field of civil engineering, and solves the technical problem that the sealing performance between an existing adhesive tape and a reinforcing steel bar is poor. Comprising a pile body and a reinforcement cage fixed in the pile body, a main reinforcement of the reinforcement cage is sleeved with a metal sealing sleeve fixedly connected with the main reinforcement and an isolation sleeve connected with the metal sealing sleeve from bottom to top, and the isolation sleeve is further provided with a lifting anchor; according to the cast-in-place pile head, the main reinforcement of the reinforcement cage is sleeved with the metal sealing sleeve fixedly connected with the main reinforcement and the isolation sleeve connected with the metal sealing sleeve from bottom to top, the lower end of the isolation sleeve is sealed through the metal sealing sleeve, and muddy water is effectively prevented from entering the isolation sleeve; the metal sealing sleeve comprises a metal pipe connected with the main rib in a sleeved mode and a silicone weather-proof glue layer arranged between the inner wall of the metal pipe and the main rib, silicone weather-proof glue has good sealing performance, and a sealing layer is formed between the main rib and the metal pipe to prevent muddy water from entering the isolation sleeve.
本发明公开了一种灌注桩桩头，涉及土木工程技术领域，解决现有胶带和钢筋之间密封性差的技术问题；包括桩体以及固定在所述桩体内的钢筋笼，所述钢筋笼的主筋由下至上套设有与所述主筋固接的金属密封套以及与所述金属密封套连接的隔离套管，所述隔离套管上还设有提升锚；本发明一种灌注桩桩头，钢筋笼的主筋由下至上套设有与主筋固接的金属密封套以及与金属密封套连接的隔离套管，隔离套管下端通过金属密封套进行密封，有效防止泥水进入到隔离套管内，金属密封套包括与主筋套接的金属管以及设置在金属管内壁与主筋之间的硅酮耐候胶层，硅酮耐候胶具有很好的密封性，在主筋与金属管之间形成一道密封层以防止泥水进入到隔离套管内。
