Slip form construction method for bridge anti-collision guardrail
The invention discloses a slip-form construction method for a bridge anti-collision guardrail, which is used for a slip-form machine and comprises the following steps: measuring and positioning a construction road on a precast beam to form a construction lead; the slip form machine is aligned in place according to the construction wire; concrete is added into the slip form machine; wherein the actual slump of the concrete is A, the standard slump of the concrete is B, and A is smaller than or equal to B +/-1cm; bridge anti-collision guardrail slip form construction is conducted along the construction guide line, and the bridge anti-collision guardrail is formed; and a deformation joint and a construction joint are formed in the bridge anti-collision guardrail. By limiting the slump of the concrete used during slip form construction of the bridge anti-collision guardrail, the compactness of the concrete after vibration is ensured while the fluidity of the concrete is ensured, the slip form construction efficiency of the bridge anti-collision guardrail is improved, the one-time slip form forming quality of the bridge anti-collision guardrail is also improved, and the construction efficiency of the bridge anti-collision guardrail is improved. And the bridge anti-collision guardrail formed by the slip form mold is prevented from generating voids and pitted surfaces.
本发明公开了一种桥梁防撞护栏的滑模施工方法，用于滑模机，所述方法包括：在预制梁上的施工道路进行测量定位，形成施工导线；根据所述施工导线将所述滑模机就位对正；向所述滑模机中添加混凝土；其中，所述混凝土的实际坍落度为A，所述混凝土的标准坍落度为B，A≤B±1cm；沿所述施工导线进行桥梁防撞护栏滑模施工，形成所述桥梁防撞护栏；在所述桥梁防撞护栏形成变形缝和施工缝。本发明通过限定桥梁防撞护栏的滑模施工时所用混凝土的坍落度，在确保混凝土具有流动性的同时，保证了混凝土经振捣后的密实度，既提高了桥梁防撞护栏的滑模施工效率，也提高了桥梁防撞护栏一次性滑模成型的质量，避免经滑模模具成型的桥梁防撞护栏产生蜂窝麻面。
