摘要
Abstract
The Longhekou Water Diversion Project pipeline adopts a pipe jacking scheme plan to cross the national highway,and the overlying strata are gravel layers with high groundwater levels.Currently,there are few cases of pipe jacking implementation in such environments,making the project implementation difficult.The engineering design adopts various solutions such as the transformation of the pipe jacking machine cutterhead,the improvement of the grouting system,the pre-reinforcement of the jacking stratum,and the monitoring technology of road surface settlement.The design scheme has been verified to be reasonable and effective through construction,and can provide reference for future pipe jacking design and construction under similar conditions.关键词
