Prefabricated transformation construction method for existing anti-collision wall with planter
The invention discloses an anti-collision wall prefabricated transformation construction method with flower grooves, which comprises the following steps of: 1, dismantling an existing anti-collision wall to expose original plate beam reserved steel bars from a plate beam; secondly, a new anti-collision wall is prefabricated in a prefabrication factory, a planter integrated with the new anti-collision wall is prefabricated in the top of the new anti-collision wall, and a connecting groove is reserved in the bottom of the new anti-collision wall; thirdly, the prefabricated new anti-collision wall and the planter are hoisted to the plate beam, and the reserved connecting groove corresponds to the position of the reserved steel bar of the plate beam; and fourthly, concrete is poured into the connecting grooves, and connection of the new anti-collision wall and the plate girder is achieved. An existing anti-collision wall formwork erecting and cast-in-place replacement method is abandoned, the new anti-collision wall prefabricated in a factory in a segmented mode is adopted, and the advantages of being convenient and fast to construct, controllable in quality, small in traffic influence, small in environmental pollution caused by construction and the like are achieved; furthermore, a planter integrated with the new anti-collision wall is prefabricated at the top of the new anti-collision wall, so that the structural damage to the new anti-collision wall is avoided, and the overall attractiveness of the new anti-collision wall is also improved.
本发明公开了防撞墙的带花槽预制化改造施工方法，包括步骤一、拆除现有防撞墙，使得板梁露出原有的板梁预留钢筋；步骤二、在预制工厂预制新防撞墙，并在新防撞墙的顶部预制与新防撞墙一体的花槽，在新防撞墙的底部预留连接槽；步骤三、再将预制好的新防撞墙和花槽吊装至板梁，并使预留的连接槽与板梁预留钢筋的位置对应；步骤四、在连接槽内灌注混凝土，实现新防撞墙与板梁的连接。本发明摒弃现有防撞墙立模现浇的更换方法，采用在工厂分节段预制的新防撞墙，具有施工便捷、质量可控、对交通影响小、施工造成环境污染小等优势；进一步地，在新防撞墙的顶部预制与其一体的花槽，不仅避免了对新防撞墙的结构破坏，也提高了新防撞墙的整体美观性。
