ZHOU HAIFENG / LI CHEN / YU DONGHE / HONG JIXIANG

The invention discloses a single-side formwork supporting system for a pile-plate retaining wall and a construction method. The single-side formwork supporting system comprises a plurality of slide-resistant piles arranged at preset positions of a side slope, retaining wall formworks arranged between the adjacent slide-resistant piles and formwork supporting structures arranged on the free sides of the retaining wall formworks. The formwork supporting structure is used for transmitting acting force of a retaining wall formwork to an anti-slide pile and comprises a supporting assembly arranged on the free side of the retaining wall formwork and an adjusting assembly arranged between the supporting assembly and the retaining wall formwork. The adjusting assembly is used for adjusting the levelness and perpendicularity of the retaining wall formwork and transmitting the acting force of the retaining wall formwork to the supporting assembly, and the supporting assembly is connected with the anti-slide pile and then transmits the acting force of the adjusting assembly to the anti-slide pile; the method is not limited to site conditions, formwork supporting frames do not need to be independently erected, and meanwhile the method is not affected by the plane relative position relation of the retaining wall and the anti-slide pile.

本发明公开了一种用于桩板式挡土墙的单侧支模体系及施工方法，包括若干个设置于边坡预设位置的抗滑桩、设置于相邻抗滑桩之间的挡土墙模板以及设置在挡土墙模板临空侧的支模结构，所述支模结构用于将挡土墙模板作用力传递给抗滑桩，所述支模结构包括设置在挡土墙模板临空侧的支撑组件和设置在支撑组件与挡土墙模板之间的调节组件，所述调节组件用于调节挡土墙模板的水平度和垂直度并用于将挡土墙模板的作用力传递给支撑组件，所述支撑组件与抗滑桩连接后将接收调节组件的作用力传递给抗滑桩；本发明可不局限于场地条件，无需单独搭设模板支撑架，同时不受挡土墙与抗滑桩平面相对位置关系影响。
