Tubular pile structure used in upper-soft lower-hard stratum and reinforcing method
The invention discloses a tubular pile structure used in an upper-soft lower-hard stratum and a reinforcing method. The tubular pile structure mainly comprises a drill hole, a first preformed hole, a second preformed hole, a prestressed tubular pile and a reinforcement cage. The first preformed hole and the second preformed hole are both located in the drill hole; the first preformed hole and the drill hole are concentrically arranged, and the axis of the second preformed hole is parallel to the drill hole; the prestressed pipe pile sinks into the drill hole, and the bottom of the prestressed pipe pile extends below the soft and hard soil interface; the reinforcement cage is placed in the preformed hole, and the top of the reinforcement cage is higher than the soft and hard soil interface; and a concrete layer is poured in the prestressed pipe pile. The reinforcing method mainly comprises the steps that a hole used for pile sinking is vertically and downwards drilled, and a drilled hole is formed; a first reserved hole is drilled in the drill hole along the axis of the drill hole, and a second reserved hole is drilled parallel to the axis of the drill hole; a prestressed pipe pile is sunk into the drilled hole, and a reinforcement cage is placed in the two kinds of reserved holes; and concrete grout is injected into the prestressed pipe pile and the two reserved holes. The device has the advantages of being simple in structure, convenient to operate and easy to implement.
本发明公开了一种用于上软下硬地层中的管桩结构及加固方法，管桩结构主要包括钻孔、第一预留孔、第二预留孔、预应力管桩和钢筋笼；第一预留孔和第二预留孔均位于钻孔内；第一预留孔与钻孔同心设置，第二预留孔的轴线与钻孔平行；预应力管桩沉入钻孔内，其底部延伸至软硬土交界面之下；钢筋笼放入预留孔内，钢筋笼的顶部高于软硬土交界面；预应力管桩内浇筑混凝土层。加固方法主要包括：竖直向下钻挖用于沉桩的孔，形成钻孔；沿着钻孔轴线在钻孔内钻挖第一预留孔，平行于钻孔轴线钻挖第二预留孔；在钻孔中沉入预应力管桩，在两种预留孔中放人钢筋笼；向预应力管桩和两种预留孔内注入混凝土浆液。本发明还具有结构简单、操作方便、容易实施的优点。
