Abstract
At present, pipe jacking adopts injected resistance reduction, so frictional resistance of outer tube wall mainly depends on the injection effect. Unfulfillment of resistance reduction brings out disadvantages of project. Factors in layers of rich water sand and gravel, such as jacking injection grouting resistance reduction for long distance and large diameter pipe, reinforcement of receiving well, and portal sealing are analyzed, and feasible methods are carried out. Finally, a success practice of once top through in sand layer is realized, indicating referential significance for similar projects afterwards.关键词
