High-strength prestressed concrete pipe pile
The invention provides a high-strength prestressed concrete pipe pile. The high-strength prestressed concrete pipe pile comprises a pipe pile body, and a fixing hoop is fixedly installed at the lower end of the outer surface of the pipe pile body in a surrounding mode; a plurality of soil inlet grooves are formed between the outer surface of the top side of the fixing hoop and the pipe pile body in an equally adjacent mode, and combined pipes are in communication with the positions, in the vertical direction, of the lower portions of the soil inlet grooves in a penetrating mode; an upper pipe, a middle pipe and a lower pipe are respectively arranged at the upper end, the middle end and the lower end of each combined pipe in sequence; upper sliding plates are slidably installed at the bottom ends in the upper pipes; and inner cavities of the middle pipes are filled with inert gas, and lower sliding plates are installed at the bottom ends of the interiors of the middle pipes in a sliding mode. According to the high-strength prestressed concrete pipe pile, when pile sinking equipment is used for driving the pipe pile into soil, soil around the lower end of the pile body can be fully utilized to supplement the stability of the pile body, the anti-pulling capacity of the pile body is improved, and the safety accident that the pipe pile is pulled up with the root can be avoided when disasters such as typhoons and earthquakes occur.
本发明提供一种高强预应力混凝土管桩，包括管桩桩身，管桩桩身的外表面下端位置环绕固定安装有固定箍；固定箍的顶侧外表面与管桩桩身之间等邻分列开设有若干个进土槽，进土槽的下方上下垂直向位置均贯穿连通有组合管；组合管的上端、中端和下端位置均依次分别开设有上管、中管和下管；上管的内部底端位置均滑动安装有上滑板；中管的内腔均填充有惰性气体，中管的内部底端位置均滑动安装有下滑板。本发明可以起到在使用沉桩设备将管桩打入土中时，可以充分利用桩身下端部位四周的泥土来补充桩体的稳固性能，提高桩体的抗拔能力，在遇到台风地震等灾害时，可避免发生管桩被连根拔起的安全事故的作用。
