Prefabricated buttressed retaining wall assembling structure and construction method
The invention discloses a prefabricated buttressed retaining wall assembling structure and a construction method. The prefabricated buttressed retaining wall assembling structure comprises a pluralityof prefabricated bottom plates, a plurality of prefabricated vertical walls, and a plurality of prefabricated buttressed plates; vertical wall slotted holes and buttressed slotted holes are formed inthe prefabricated bottom plates and correspond to the prefabricated vertical walls and the prefabricated buttressed slotted holes respectively; every two prefabricated vertical walls are formed by assembling a groove structure and a protruding structure; a plurality of vertical wall tenons are arranged under the prefabricated vertical walls; a plurality of pairs of annular closed steel bars matched with one another are embedded at the positions where the prefabricated vertical walls and the corresponding prefabricated buttressed plates are assembled; and the lower parts of each prefabricatedvertical wall and the corresponding prefabricated buttressed plate are connected with the corresponding prefabricated bottom plates. The construction method comprises the following steps that during construction, at first, a leveling layer is manufactured, then the prefabricated bottom plates are hoisted, the prefabricated vertical walls and prefabricated buttressed plates are installed on the prefabricated bottom plates, and finally, longitudinal steel bars are inserted into the annular closed steel bars that overlap between the precast vertical walls and prefabricated buttressed plates, andare cast with high-strength non-shrinkage concrete. The prefabrication of a relatively high buttressed retaining wall filled with soil can be realized, and the construction speed is increased.
本发明公开了预制装配的扶壁式挡土墙拼装构造及施工方法，包括若干预制底板、若干预制竖墙和若干预制扶壁板；预制底板对应预制竖墙和预制扶壁板分别设有竖墙槽孔和扶壁槽孔；每两块预制竖墙均籍由凹槽结构和凸出结构拼接；预制竖墙的下面均设有多个竖墙凸榫；预制竖墙与相应的预制扶壁板拼接的位置均预埋若干对互相匹配的环形封闭钢筋；每一预制竖墙和相应的预制扶壁板的下面均与相应的预制底板连接。施工时，首先制作找平层，然后吊装预制底板，在预制底板上安装预制竖墙和预制扶壁板，最后在预制竖墙和预制扶壁板、之间重叠的环形封闭钢筋内插入纵向钢筋用高强无收缩混凝土浇筑。本发明可实现填土较高的扶壁式挡土墙的预制装配，加快施工速度。
