Construction method for underneath passing of road section with heavy traffic pressure
The invention discloses a construction method for an underneath pass road in a road section with heavy traffic pressure, which comprises the following steps of: arranging a pile type ground anchor asa pile foundation; fixedly installing prestressed concrete tunnel gates at the two ends of the roadbed, holes are drilled in the roadbed side by side in the direction of the tunnel gates at equal intervals to generate reserved mud jacking holes, the roadbed and the tunnel gates are arranged on pile type ground anchors, and the bottoms of the tunnel gates are connected with the pile type ground anchors; steel pipes are arranged in the roadbed and comprise a top steel pipe and two side steel pipes, and reinforcing steel bars are arranged in the steel pipes; and grouting construction is conductedbetween the top steel pipes, between the top steel pipes and the soil body and in the top steel pipes. The method has the advantages of simple and advanced technology, reliable and stable safety, small influence degree on original road traffic, convenience in main body structure construction and the like.
本发明公开了一种用于交通压力繁重路段下穿道路的施工方法，包括以下步骤：设置桩式地锚，作为桩基础；在路基两端固装预应力混凝土洞门，在路基上等距并排沿洞门方向钻孔，生成预留压浆孔洞，路基与洞门均设置在桩式地锚上，洞门底部与桩式地锚连接；在路基内部设置钢管，钢管包括顶部钢管和两侧钢管，在钢管内部设置钢筋；在顶部钢管之间、顶部钢管与土体之间以及顶部钢管之内进行压浆施工。本发明具有技术方面简单先进、安全方面可靠稳定、对原有道路交通影响程度小、主体结构施工便捷等优点。
