Retaining pile plate type retaining wall for widening and expanding existing slide-resistant piles on road and construction method
The invention relates to a reserved pile plate type retaining wall for widening and expanding existing anti-slide piles on a road and a construction method. The construction method comprises the following steps that the anti-slide piles are constructed above anti-slide pile prefabricated lock catches through door-shaped square steel supports; driving Larsen steel sheet piles, and fixedly connecting the Larsen steel sheet piles with the existing anti-slide piles and the newly-added anti-slide piles through supporting rods; prefabricated assembly type cross beams are mounted at the tops of the existing anti-slide piles and the newly-added anti-slide piles; and carrying out highway pavement widening construction. The method has the beneficial effects that the steel bar hoisting and adjusting support is formed through the prefabricated lock catches and the door-shaped square steel support by adopting a rectangular anti-slide pile mechanical rapid hole forming technology, and the construction quality and the construction efficiency of the newly-added anti-slide pile are improved; the existing anti-slide pile reinforcing technology is adopted, an existing structure is reutilized, the existing anti-slide piles are reinforced, the strength of the retaining wall is improved, and the construction cost is greatly reduced.
本发明涉及一种公路加宽扩建既有抗滑桩留用桩板式挡墙及施工方法，包括以下步骤：抗滑桩预制锁扣上方通过门形方钢支架施工抗滑桩；打设拉森钢板桩，通过支撑杆与既有抗滑桩和新增抗滑桩连接固定；在既有抗滑桩和新增抗滑桩顶部安装预制装配式横梁；进行公路路面拓宽施工。本发明的有益效果是：采用矩形抗滑桩机械快速成孔技术通过预制锁扣及门形方钢支架形成钢筋吊放调整支架，提高了新增抗滑桩的施工质量、施工效率；采用既有抗滑桩补强加固技术，对已有结构二次利用，通过对既有抗滑桩进行补强，提升挡墙的强度，极大程度地降低了施工成本。
