Bridge abutment rear bumping disease combined treatment method
The invention provides a bridge abutment rear bumping disease combined treatment method which comprises the following steps: digging out building materials in a replacement area and digging out a broken stone sand cushion layer; maintaining building materials of a conventional soil filling area; laying an anti-seepage geomembrane between the replacement filling area and the conventional soil filling area; filling the replacement area with bubble mixed light soil; laying plain concrete on the bubble mixed light soil; laying a butt strap on the plain concrete; and laying asphalt concrete laid onthe butt strap. The foamed mixed light soil used in the replacement area is a novel light material which is light in weight, smaller than water in capacity, capable of standing upright after being solidified and free of side pressure on the abutment back of the bridge, and the side pressure of the abutment back is reduced; reinforcing steel bars of the butt strap are enlarged and thickened, structure thickness is increased, construction is convenient, and manufacturing cost is low; post-construction settlement of the abutment back is effectively reduced, and driving safety and comfort are improved.
本发明提供了一种桥梁台后跳车病害组合处治方法，包括：挖除换填区的建筑材料，并且挖除到碎石砂垫层；保持常规填土区的建筑材料；在所述换填区和所述常规填土区之间铺设防渗土工膜；往所述换填区填充气泡混合轻质土；在所述气泡混合轻质土上铺设素混凝土；在所述素混凝土上铺设搭板；在所述搭板上铺设沥青混凝土。在换填区所使用的起泡混合轻质土是一种质量轻、容量小于水重、固化后可直立，对桥梁台背无侧压力的新型轻质材料，减小台背的侧方压力；搭板的钢筋加大加粗、构造厚度加厚，施工方便、造价经济；有效减少桥台台背的工后沉降，提高行车的安全舒适性。
