Pile-breaking-free pile head reinforcing steel bar protection device and construction method and dismantling method thereof
The invention discloses a pile-breaking-free pile head reinforcing steel bar protection device, a construction method and a dismantling method. The pile-breaking-free pile head reinforcing steel bar protection device comprises a steel mold and reinforcing steel bar sleeves arranged on pile head reinforcing steel bars in a sleeving mode. When the reinforcement sleeve sleeves the pile head reinforcement, a certain gap is reserved between the outer wall of the reinforcement sleeve and the outer wall of the steel mold; the internal space of the steel mold is a pouring space, and over-pouring concrete is poured in the pouring space; and the upper end of the steel mould is used as an elevation indicating surface of the over-poured concrete. According to the protection device, concrete and steel bars are isolated through the steel die and the steel bar sleeve to achieve the purpose of protecting the steel bars, pile head steel bars and concrete of an over-grouting part are prevented from making contact with surrounding soil, then the pile breaking-free purpose is achieved, meanwhile, the steel die is used for marking the elevation of the over-grouting part, the problem of ultrahigh pouring is avoided, resources are saved, and the construction cost is reduced. And construction and dismantling are convenient.
本发明公开了一种免破桩桩头钢筋保护装置及施工方法和拆除方法，包括钢模以及套设于每根桩头钢筋的钢筋套筒；钢筋套筒套设于桩头钢筋时，钢筋套筒外壁与钢模的外壁之间预留一定空隙；钢模内部空间为浇筑空间，浇筑空间内浇筑超灌混凝土；钢模的上端作为超灌混凝土的标高指示面。本发明的保护装置通过钢模和钢筋套筒隔离混凝土和钢筋以达到保护钢筋的目的，避免桩头钢筋和超灌部分混凝土和周围土体接触，进而实现免破桩的目的，同时利用钢模标识超灌部分的标高，避免浇筑超高的问题，节约资源，方便施工和拆除。
