Embodiment 1
[0213] Embodiment 1: certain railway construction.
[0214] Construction started in August 2019 and was completed on December 20, 2019. The angle between the project and the railway is 42°, the total length is 190.72m, and the span is set as 1-32mT beam + 1-108m steel truss beam 1+1-32mT beam. The second hole is located at DK5+397.53, DK5+449.67, and DK5+457.13 mileage respectively. There are single-line and double-line, and the steel truss beam 1 structure with a span of 108m is adopted.
[0215] The invention effectively shortens the construction period, saves the construction cost, ensures the safety of railway operation and improves the engineering quality.
