Waist beam stable construction method based on smooth support piles
The invention discloses a waist beam stable construction method based on smooth support piles. The construction method comprises the steps of measuring and positioning, construction of the support piles and the water stop piles, excavation of a first layer of earthwork, construction of the top beams, construction of the top beam connecting tie steel bars and the first pre-stressed anchor cables, excavation of a second layer of earthwork, construction of the waist beams, construction of the waist beam connecting tie steel bars and the second pre-stressed anchor cables, and fixed construction of the connecting tie steel bars. According to the construction method provided by the invention, a traditional waist beam construction mode can be changed, damage to a prestressed structure of the smooth support pile is avoided, normal exertion of a foundation pit support system is ensured, and the waist beam can be subjected to gravity, tensile force provided by the vertical steel tie bars, prestress of the second prestressed anchor cable and counter-acting force of the support pile to the waist beam; stress balance is formed, the unbalanced stress state of the waist beam is changed, and the waist beam can better play a role of a foundation pit supporting system.
本发明公开了一种基于光滑支护桩的腰梁稳固施工方法，所述施工方法包括测量定位、支护桩、止水桩施工及第一层土方开挖、冠梁、冠梁联系拉结钢筋及第一道预应力锚索施工、第二层土方开挖、腰梁、腰梁联系拉结钢筋及第二道预应力锚索施工、联系拉结钢筋固定施工。本发明的所提供的施工方法可以改变传统腰梁施工方式，避免光滑支护桩自身预应力结构的破坏，保证了基坑支护体系的正常发挥，可以使腰梁受重力、竖向拉结钢筋提供的拉力、第二道预应力锚索的预应力、支护桩对腰梁的反作用力，形成受力平衡，改变腰梁的受力不平衡状态，使腰梁更好的发挥基坑支护体系作用。
