Unloading type combined retaining structure and construction method thereof
The invention relates to an unloading type combined retaining structure and a construction method thereof. The unloading type combined retaining structure is divided into two types, wherein one type is a combined retaining structure jointly formed by supporting piles, unloading plate supporting piles, supporting pile top connecting beams, unloading plates, longitudinal connecting beams, transversesupporting beams, plate top backfill soil and other members; and the second structure is a combined retaining structure jointly formed by the supporting piles, the supporting pile top connecting beams, the unloading plates, the longitudinal connecting beams, ribbed beams or ribbed plates, the longitudinal supporting beams, reinforcing waist beams, the plate top backfill soil and other members. According to the unloading type combined retaining structure, the unloading effect of the unloading plates is fully utilized, the soil pressure acting on the supporting structure is effectively reduced,and the foundation pit supporting structure can be formed without occupying the space outside a red line, without implementing an anchor rod on the outer side of a foundation pit and without arranging a support inside the foundation pit. The unloading type combined retaining structure is clear and definite in stress, reliable in quality and high in construction speed, can greatly wide the application range of the supporting and retaining type supporting and retaining structure, and can replace an inner supporting and retaining structure under partial conditions.
本申请涉及卸荷式组合支挡结构及其施工方法。卸荷式组合支挡结构分为两种型式：一种是由支护桩、卸荷板支撑桩、支护桩顶连梁、卸荷板、纵向连接梁、横向支撑梁、板顶回填土及其他构件共同形成组合支挡结构；第二种是由支护桩、支护桩顶连梁、卸荷板、纵向连接梁、肋梁或肋板、纵向支撑梁、加强腰梁、板顶回填土及其他构件共同形成组合支挡结构。该支挡结构充分利用了卸荷板的卸荷作用，有效减小了作用在支护结构上的土压力，是一种不占用红线外空间、不在基坑外侧实施锚杆及不在基坑内部设置支撑即可形成的基坑支护结构。该支挡结构受力清晰明确，质量可靠，施工速度快，大幅增加支挡式支护结构的应用范围，部分情况下可替代内支撑支护结构。
