Inclined throwing support system with prestress capable of being compensated on line and construction method of inclined throwing support system
The invention discloses an inclined throwing support system with prestress capable of being compensated online and a construction method of the inclined throwing support system, and belongs to the technical field of inclined throwing supports. The device comprises an H-shaped steel inclined strut system, a bearing platform foundation and a fender post, the H-shaped steel inclined strut system is obliquely arranged between the bearing platform foundation and the fender post, the lower portion of the H-shaped steel inclined strut system is connected with the bearing platform foundation, and a back pressure connecting assembly is arranged on the upper portion of the H-shaped steel inclined strut system. The back pressure connecting assembly comprises a back pressure bracket, a supporting bracket and an H-shaped steel enclosing purlin. According to the inclined throwing and supporting system, downward constraining force is provided through the back pressure bracket, so that it is ensured that the joint of the H-shaped steel inclined supporting system and the fender post does not deviate, and then the overall stability of the inclined throwing and supporting system is ensured; prestress on-line adjustment can be conducted through the prestress on-line compensation component, the component has a self-locking function, the supporting force of the H-shaped steel inclined strut system can adapt to changes of temperature stress and the like caused by temperature changes, and therefore a guarantee is provided for supporting safety of a foundation pit.
本发明公开了一种预应力可在线补偿的斜抛撑系统及其施工方法，属于斜抛撑技术领域。本发明包括H型钢斜撑系统、承台基础和围护桩，所述的H型钢斜撑系统在承台基础和围护桩之间倾斜设置，H型钢斜撑系统的下部与承台基础连接，所述的H型钢斜撑系统的上部设置有反压连接组件，反压连接组件包括反压牛腿、支撑牛腿和H型钢围檩。本发明的斜抛撑系统，通过反压牛腿提供向下的约束力，从而确保H型钢斜撑系统与围护桩的连接处不会产生偏移，进而保证斜抛撑系统的整体稳定性；通过预应力在线补偿构件能够进行预应力在线调整，该构件具有自锁功能，H型钢斜撑系统的支撑力能够适应气温变化带来的温度应力等的变化，从而为基坑的支护安全提供保障。
