Construction method of special-shaped cast-in-place concrete planter anti-collision guardrail
The invention relates to a construction method of a special-shaped cast-in-place concrete planter anti-collision guardrail, which comprises the following steps of: 1, positioning and paying off, and setting out a construction side line of the planter anti-collision guardrail on a foundation; 2, implanting connecting steel bars into the foundation, bonding a steel bar net, and making PVC pipes penetrate into the steel bar net; 3, moving the movable formwork supporting frame to one side of the planter anti-collision guardrail to be poured, and adjusting the movable formwork supporting frame to be supported by the adjustable supporting feet; and 4, pouring concrete into a space formed by the inner side formwork, the outer side formwork, the U-shaped inner formwork and the end formwork, constructing a planter anti-collision guardrail, and spraying water for maintenance after vibration compaction. The method has the beneficial effects that the pouring quality of concrete is guaranteed, and the structural reliability is high; the difficulty of erecting the upper template of the viaduct is reduced, the erecting efficiency of the template is improved, and the appearance and linear straightness of the planter anti-collision guardrail are ensured; the construction efficiency of the planter anti-collision guardrail is improved, and the construction period is shortened.
本发明涉及一种异型现浇混凝土花槽防撞护栏施工方法,包括步骤:步骤1:定位放线,在基础上放样出花槽防撞护栏的施工边线;步骤2:在基础上植入联结钢筋,并绑扎钢筋网,并在钢筋网内穿入PVC管;步骤3:将移动式模板支撑架移动至待浇筑的花槽防撞护栏一侧,将移动式模板支撑架调整至由可调撑脚支撑;步骤4:向内侧模板、外侧模板、U型内模以及端模组成的空间内浇筑混凝土,施作花槽防撞护栏,振捣密实后洒水养护。本发明的有益效果是:保证混凝土的浇筑质量,结构的可靠性高;降低了高架桥上模板支设的难度,提高模板的支设效率,保证花槽防撞护栏的外观及线型顺直;提高了花槽防撞护栏的施工效率,缩短施工周期。
