Construction method of damaged foam concrete repairing structure of active retaining wall
The invention relates to a construction method of a damaged foam concrete repairing structure of an active retaining wall. The construction method comprises the following steps of: 1) excavating a working face; 2) constructing a post-reinforced foundation; 3) constructing a reinforced anchor rod; 4) excavating a step; 5) constructing a drainage system; 6) mounting a claw-shaped anchor frame; 7) pouring foam concrete; 8) constructing a foam concrete core-filled retaining wall; 9) constructing a supporting wall; and 10) constructing post-poured concrete. The construction method has the beneficial effects that a steel bar framework is arranged in the post-reinforced foundation of the retaining wall so that the whole bearing capability of the foundation of the retaining wall can be improved; the claw-shaped anchor frame is arranged in the foam concrete, so that the foam concrete and original soil have a common effect, the friction force between the foam concrete and the original soil is improved and the side pressure on the retaining wall is reduced; and a stud plate is arranged in the foam concrete core-filled retaining wall so that the integrity of the foam concrete core-filled retaining wall and an original retaining wall is improved.
本发明涉及现役挡墙病害泡沫混凝土修复结构的施工方法，包括步骤：1)工作面开挖；2)后加固基础施工；3)加固锚杆施工；4)开挖台阶；5)排水体系施工；6)安装爪型锚架；7)泡沫混凝土浇筑；8)泡沫混凝土灌芯挡墙施工；9)支撑墙施工；10)后浇混凝土施工。本发明的有益效果是：挡墙后加固基础内设置钢筋骨架，可提高挡墙基础的整体承载力；在换填泡沫混凝土内设置爪型锚架，可使泡沫混凝土与原土共同作用，提高两者间的摩擦力，减少对挡墙的侧压力；在泡沫混凝土灌芯挡墙内设置栓钉板，提高泡沫混凝土灌芯挡墙与原挡墙的整体性。
