Safety analysis of gas pipeline crossing Xiaozuo River Ferry
The current situation of Xiaozuo River Aqueduct is a rectangular single channel structure,and the lower structure of the river channel is a pile column integrated support structure.The cast-in-place piles penetrate 1m deep into the weakly weathered rock,and 5m below the ground is composed of pebbles.The newly-built Luquan to Jingxing gas pipeline crosses the aqueduct in one go,using the top-down method to pass through the gravel layer between the foundation cast-in-place piles.From the aspects of horizontal distance and burial depth,it is analyzed and demonstrated that the calculated scouring depth is 2.68m,and the burial depth of the pipe top and the spacing between the pipe walls meet the requirements of the specifications.The crossing plan is reasonable.
