Variable cross-section sleeve pile supporting system and construction method thereof
The invention discloses a variable cross-section sleeve pile supporting system and a construction method thereof, and belongs to the field of rock mechanics, the supporting system comprises a large pile and a small pile which are concentrically arranged up and down, the large pile is embedded into a rock stratum, the small pile is embedded into the large pile, reinforcement cages are arranged in the large pile and the small pile, and high-strength concrete is adopted for pouring; the embedded positions of the large piles and the small piles are connected by pouring concrete; the large piles are supported by adopting steel supports within the upper large pile supporting range, and the small piles are fixed by adopting anchor cables within the lower small pile supporting range; according to the scheme, an upper-supporting and lower-anchoring mode is adopted for fixing, a rock shoulder and a fertilizer groove are omitted, and the construction land occupation can be reduced; through the adaptive construction technology, the construction procedures are effectively reduced, and construction is convenient; by combining the design of a small pile limiting device and the like, concentric stress of the upper pile body and the lower pile body is ensured, the construction difficulty of small piles in sleeve piles is overcome, construction is convenient, economic benefits are good, practical value is high, and wide popularization and application value is achieved.
本发明公开一种变截面套桩支护体系及其施工方法，属于岩土力学领域，所述支护体系包括上下同心设置的大桩和小桩，大桩嵌入岩层中，小桩嵌入大桩中，大桩和小桩的内部均设有钢筋笼并采用高强度混凝土浇筑，在大桩和小桩的嵌套处通过浇筑混凝土连接；在上部大桩支护范围内采用钢支撑对大桩进行支护，在下部小桩支护范围内，采用锚索对小桩进行固定；本方案采用上撑下锚的形式进行固定，取消了岩肩和肥槽，可减少施工占地；并通过适应性的施工工艺，有效减少了施工工序，方便施工；结合小桩限位装置等设计，确保了上下桩身同心受力，克服套桩中小桩的施工难点，施工方便，经济效益好实用价值高，具有广泛的推广及应用价值。
