Tubular pile post-grouting device for blocking tubular pile through air bag and grouting method of tubular pile post-grouting device
The invention relates to a pipe pile post-grouting device for blocking a pipe pile through an air bag and a grouting method thereof, and belongs to the technical field of constructional engineering grouting. The device comprises a prestressed pipe pile, a drill rod and the air bag, the drill rod is arranged in the prestressed pipe pile, a drill bit is arranged at the bottom end of the drill rod, and a drill rod grouting hole is formed in the bottom of the drill rod. The air bag is arranged outside the drill rod, the top of the air bag is connected with a high-pressure air pipe, the end of the high-pressure air pipe is connected with inflation equipment, and the air bag can block a gap between the drill rod and the inner wall of the prestressed pipe pile in an expansion state, so that grouting slurry is prevented from continuing to move upwards. When grouting is conducted in the drill rod, grout rises to the position of the air bag and is blocked by the air bag, the situation that the grout overflows the ground to pollute the environment is prevented, and when the grout is blocked, along with increase of grouting pressure, the grout cannot flow upwards and can only be forced to permeate into a lower stratum gap and a lateral stratum gap, and a better grouting effect can be achieved.
本发明的利用气囊封堵管桩的管桩后注浆装置及其注浆方法属于建筑工程注浆技术领域，该装置包括预应力管桩、钻杆和气囊，钻杆设置在预应力管桩内，钻杆的底端设有钻头，钻杆的底部设有钻杆注浆孔。气囊设置在钻杆的外部，气囊的顶部连接有高压气管，高压气管的端部与充气设备连接，气囊在膨胀状态下可将钻杆与预应力管桩内壁之间的间隙封堵，从而阻止注浆浆液继续向上运动。在向钻杆内注浆时，浆液上升至气囊位置而被气囊阻挡，防止浆液溢出地面污染环境，浆液受阻同时，随着注浆压力的增大，浆液无法向上流动，只能被迫向下部及侧向地层缝隙渗透，可实现更好的注浆效果。
