Abstract

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.

Description

technical field [0001] The invention relates to the field of urban road engineering, in particular to a construction method for underpassing roads in road sections with heavy traffic pressure.
