Abstract：
The heat supply pipeline mined tunnel project on Chaoyang North Road of Beijing is located on an area where underground water is rich and underground water level is high, and ground dewatering is infeasible, so full-face grouting water stop technique shall be adopted. Five road stretches having different hydrogeological conditions are tested and soil is sampled on field for mixing proportion test before construction of each test stretch. A set of parameters applicable to grouting water stop construction in water-rich stratum are studied to guarantee that heat supply pipeline mined tunnel construction satisfies the requirements of green urban construction.
