Abstract：
During the construction of Chaoyang Park Bridge across East Fourth Ring Road, the heat pipeline of Nongzhan South Road is located in Chaoyang Park Bridge. The strata are silt, fine sand, stagnant water and submersible strata. To ensure the safety of the surrounding roads, sand flow, collapse and loss of work surface are avoided stability and other endanger the construction safety situation, the construction of underground tunnel excavation and slurry balance pipe jacking two kinds of laying way, receiving pipe jacking in the tunnel construction of the whole section of the strata using full-face waterproof grouting, local graded cross section, dynamic monitoring, to ensure the safety of the heat pipe through.
