Prestressed pipe pile long spiral guide hole grouting and self-weight type pile planting construction method
The invention relates to the technical field of prestressed pipe piles, and discloses a prestressed pipe pile long spiral guide hole grouting and self-weight type pile planting construction method which comprises the following construction steps that (1) forward drilling is conducted in a soil layer through a long spiral drill rod, a pile hole is formed, and the bottom of the pile hole is a bearing layer; in the process of reversely lifting the long spiral drill rod from the pile hole, grouting the pile hole until the pile hole is filled with slurry to a set height; (2) the prestressed pipe pile is hoisted to the position above the pile hole through a crane; (3) the prestressed pipe pile is sleeved with a hoisting structure, after a bucket of an excavator is connected with the hoisting structure, the crane is separated from the prestressed pipe pile, the bucket is connected with the hoisting structure, and the prestressed pipe pile is made to be in a vertical shape; the bucket moves downwards, and the prestressed pipe pile is planted into the pile hole through the gravity of the prestressed pipe pile; and (4) the prestressed pipe pile is vibrated and pressed from top to bottom through a vibration hammer till the lower portion of the prestressed pipe pile is embedded into the bearing stratum. The construction quality requirement is ensured, and the efficient, reliable and economical effects are achieved.
本发明涉及预应力管桩的技术领域，公开了预应力管桩长螺旋引孔注浆与自重式植桩施工方法，包括以下施工步骤：1)、通过长螺旋钻杆在土层中正向钻进，形成桩孔，桩孔的底部为持力层；将长螺旋钻杆从桩孔中反向提升的过程中，往桩孔中注浆，直至浆体填充至设定高度；2)、利用吊机将预应力管桩吊至桩孔的上方；3)、在预应力管桩上套设吊装结构，利用挖掘机的铲斗与吊装结构连接后，吊机与预应力管桩脱离，利用铲斗与吊装结构连接，将预应力管桩呈竖直状；铲斗朝下移动，预应力管桩利用自身重力植入桩孔中；4)、利用振动锤自上而下振压预应力管桩，直至预应力管桩的下部嵌入持力层中。确保施工质量要求，达到了高效、可靠、经济的效果。
