Protective sleeve for steel bar at pile head of cast-in-situ bored pile
The invention discloses a cast-in-situ bored pile head reinforcing steel bar protection sleeve which sleeves a reinforcing steel bar of an over-grouting part and comprises the reinforcing steel bar, a reinforcing steel bar protection sleeve body, a hollow hole pre-buried round pipe, a bottom sealing sleeve and a top protection sleeve. The bottom sealing sleeve and the reinforcing steel bar protection sleeve sequentially penetrate through the reinforcing steel bar of the over-grouting part, the bottom sealing sleeve is connected with the outer wall of the lower end of the reinforcing steel bar protection sleeve, and the top protection sleeve is connected with the outer wall of the upper end of the reinforcing steel bar protection sleeve; and the hollow pre-embedded round pipe is fixedly connected with the steel bar protection sleeve. The pile head reinforcing steel bar protection sleeve device is adopted for isolating pile head reinforcing steel bars from pile head over-pouring concrete, the function of protecting the integrity of the pile head reinforcing steel bars is achieved, and damage to pile head main reinforcing steel bars caused by chiseling away concrete after the pile head is formed is prevented; the construction method is simple and easy to operate; the method is not only suitable for large-scale pile group foundation trial, but also suitable for small-scale and low-cost pile foundation construction.
本发明公开了一种钻孔灌注桩桩头钢筋保护套管，钻孔灌注桩桩头钢筋保护套管套在超灌部分的钢筋上，包括：钢筋、钢筋保护套管、掏心孔预埋圆管、底部密封套和顶部保护套；底部密封套、钢筋保护套管依次穿入超灌部分的钢筋，底部密封套与钢筋保护套管下端外壁连接，顶部保护套与钢筋保护套管上端外壁连接；掏心孔预埋圆管与钢筋保护套管固定连接。本发明采用此桩头钢筋保护套管装置隔离桩头钢筋与桩头超灌混凝土，既起到保护桩头钢筋完整性的功能，又防止了桩头成型后凿除混凝土对桩头主筋的损伤；施工方法简单，易于操作；不仅对大规模群桩基础试用，更适用于小规模低成本的桩基础施工。
