Pipe pile core concrete pouring leakage-proof device and using method
The invention discloses a pipe pile core concrete pouring anti-leakage device and a using method thereof. The pipe pile core concrete pouring anti-leakage device comprises a pile core which is inserted into a prefabricated pipe pile from top to bottom; the pile core steel supporting plate is mounted at the lower end of the pile core; the leakage-proof ring is arranged between the pile core steel supporting plate and the inner side wall of the prefabricated pipe pile, the whole leakage-proof ring is of a structure with the outer side higher than the inner side, a first conical surface is arranged between the outer side edge of the leakage-proof ring and a central folded edge of the leakage-proof ring, a second conical surface is arranged between the central folded edge and a bottom folded edge of the leakage-proof ring, and the first conical surface is a conical surface. The inner side of the bottom folded edge extends to form a horizontal part which is connected with a pile core steel supporting plate, and the included angle between the first conical surface and the second conical surface is larger than 90 degrees. The problem that concrete leaks from a gap between the supporting plate and the inner wall of the prefabricated pipe pile when concrete is poured into the pile core of the prefabricated hollow pipe pile can be solved.
本发明公开了一种管桩桩芯灌注混凝土防漏装置及其使用方法，包括桩芯，由上至下插入设置在预制管桩的内部；桩芯钢托板，安装在桩芯的下端；防漏环，设置在桩芯钢托板与预制管桩的内侧壁之间，所述的防漏环整体呈外侧高内侧低的结构，所述的防漏环的外侧边缘与防漏环的中心折边之间为第一锥面，所述的中心折边与防漏环的底部折边之间为第二锥面，所述的底部折边的内侧延伸为水平部与桩芯钢托板相连，所述的第一锥面与第二锥面之间的夹角大于90°。本发明可以解决预制空心管桩桩芯灌注混凝土时托板和预制管桩内壁的空隙渗漏混凝土问题。
