Anti-floating composite foundation structure of box arch-shaped corrugated steel channel and construction method
The invention discloses an anti-floating composite foundation structure of a box arch-shaped corrugated steel channel and a construction method. The composite foundation structure sequentially comprises a foundation, a reinforced concrete cushion layer and a solidified soil filling layer from bottom to top, wherein the solidified soil filling layer is formed by premixed flow state self-compacting solidified soil. Vertical reinforcing steel bars are arranged in the solidified soil filling layer, the upper ends of the vertical reinforcing steel bars are fixedly connected with a bottom plate of the box arch-shaped corrugated steel channel, and the lower ends of the vertical reinforcing steel bars are fixedly connected with a reinforcing steel bar net in the reinforced concrete cushion layer. According to the construction method of the box arch-shaped corrugated steel channel, the box arch-shaped corrugated steel channel with the composite foundation structure can be implemented, and the solidified soil filling layer and the reinforced concrete cushion layer are connected with the bottom plate of the box arch-shaped corrugated steel channel through the vertical reinforcing steel bars to form the balance weight of the box arch-shaped corrugated steel channel, upward buoyancy from underground water is resisted, meanwhile, the elevation of the ground plane in the pipe gallery formed after channel connection does not need to be changed, and the application scene of the corrugated steel structure is widened.
本发明公开了一种箱拱形波纹钢通道抗上浮的复合基础结构及施工方法，其中复合基础结构自下而上依次包括地基基础、钢筋混凝土垫层及由预拌流态自密实固化土形成的固化土充填层。固化土充填层中设有竖向钢筋，竖向钢筋的上端与箱拱形波纹钢通道的底板固定连接，竖向钢筋的下端与钢筋混凝土垫层中的钢筋网固定连接。通过本发明公开的箱拱形波纹钢通道的施工方法，可以实施出具有上述复合基础结构的箱拱形波纹钢通道，固化土充填层及钢筋混凝土垫层通过竖向钢筋与箱拱形波纹钢通道的底板连接，成为箱拱形波纹钢通道的配重，抵抗来自地下水的上浮力的同时，无需改变通道连接后形成的管廊内部的地平面标高，拓宽了波纹钢结构的应用场景。
