Hollow slab bridge dismantling construction method for preserving hollow slabs
The invention relates to a hollow slab bridge dismantling construction method for preserving hollow slabs, and belongs to the technical field of bridge construction. At present, a large amount of manpower is needed for dismantling hollow slabs, the hollow slabs are prone to being damaged, and the dismantled hollow slabs cannot be used again. The method comprises the following steps: firstly, removing mortar in a horseshoe part seam at the lower part of a hinge joint from a bridge floor by using an air pick, then removing hinge joint concrete above a horseshoe by using a high-pressure water jet cutter, then cutting downwards on the bridge floor close to a hollow slab to be dismantled, chiseling a plurality of grooves along a cutting seam, putting a hydraulic splitting clamp, splitting from one end of a bridge span to the other end, and finally removing the hinge joint concrete from the hollow slab to be dismantled. And the hollow slab to be dismantled is separated from the hinge joint concrete. According to the scheme, operation under the bridge is little, tools are simple, it can be guaranteed that the disassembled hollow slabs are complete, the overhanging steel bars of the hollow slabs can be preserved, the hollow slabs can be conveniently reused after being trimmed, resource waste is avoided, and the double-carbon target can be achieved easily.
本发明涉及一种保全空心板的空心板桥拆除施工方法，属于桥梁施工技术领域。目前的空心板拆除需要大量人工，容易破坏空心板，使拆下来的空心板不能被再次使用。本发明首先从桥面下，用风镐清除铰缝下部马蹄部位缝中的砂浆，再用高压水刀清除马蹄上方的铰缝混凝土，随后在桥面上靠近将要拆除的空心板向下切割，再沿切割缝凿出多个凹槽，放入液压劈裂钳，从桥跨的一端向另一端劈裂，将要拆除的空心板就会脱离铰缝混凝土。本方案桥下作业少且工具简单，可确保拆下来的空心板完整，且能保全空心板的外伸钢筋，便于修整后再次使用，避免资源浪费，有助于实现“双碳”目标。
