Three-main-truss steel truss girder small-distance double-sliding-block pushing control method
The invention discloses a small-distance double-slider pushing control method for a steel truss girder with three main trusses. The method comprises the following steps of: adjusting the height of a supporting point pad to optimize pushing reaction force, performing multi-stroke pushing by using double sliders, and eliminating the adverse effect of horizontal traction force in a single-slider state during pushing; according to the small-distance double-sliding-block pushing control method for the three-main-truss steel truss girder, the pushing reaction technology is optimized by adjusting the height of a supporting point pad, the reaction force of a pier-side support in the pushing process can be effectively reduced, the amplitude of the reaction force of a pier body is reduced and controlled to be not smaller than 10%-15%, the double-sliding-block multiple-stroke pushing technology is used, construction is simple, and the construction efficiency is high. Compared with the prior art, the method has the advantages that the cost is not required to be increased, the risk of steel truss girder pushing construction is reduced, and the risk of the pier body in the pushing process is controllable, so that the eccentric bending moment of the pier on which the pier-side bracket is positioned is reduced, the construction difficulty is reduced, the construction cost is saved, and the engineering construction safety is guaranteed.
本发明公开了一种三主桁钢桁梁小布距双滑块顶推控制方法，调整支点抄垫高度优化顶推支反力技术，使用双滑块进行多次行程顶推技术，顶推时单滑块状态下水平牵引力不利影响消除技术；该三主桁钢桁梁小布距双滑块顶推控制方法，通过调整支点抄垫高度优化顶推支反力技术，可以有效降低墩旁支架在顶推过程中的支反力，降低墩身支反力幅度控制不小于10％‑15％，使用双滑块进行多次行程顶推技术，施工简单，无需增加成本，降低了钢桁梁顶推施工的风险，使得顶推过程中墩身风险可控，因此本申请的技术方案减小了墩旁支架所在墩的偏心弯矩，降低了施工难度，节约了施工成本，保障了工程施工安全性。
