Protected object displacement real-time control method in underground engineering crossing process
The invention relates to a protected object displacement real-time control method in an underground engineering crossing process in the field of underground trenchless engineering. The method comprises the following steps that a) an isolation area (1) is drawn between an underground engineering crossing construction surface (5) and a protected object (4); b) a bag (2) is placed in a soil body of the isolation area (1); c) a fluid (3) is contained in the bag (2); d) stress is applied to a part, on the outer side of the bag (2), of the soil body through the fluid (3) in the bag (2) to compensatestress loss caused by underground engineering crossing construction; and e) displacement of the protected object (4) is controlled through compensation of soil body stress loss on one side of the protected object (4). The method can control the displacement of the protected object (4) in real time, can completely eliminate the influence of the underground engineering crossing construction, achieves zero-displacement trenchless construction, and is low in manufacturing cost, controllable in quality, and high in safety degree and reliability.
本发明涉及地下非开挖工程领域中的一种地下工程穿越过程中被保护对象位移实时控制方法，包括以下步骤：a)在地下工程穿越施工面(5)与被保护对象(4)之间划立隔离区(1)；b)在隔离区(1)的土体内置入袋子(2)；c)在袋子(2)内盛装流体(3)；d)通过袋子(2)内的流体(3)对袋子(2)外侧的土体施加应力，补偿因地下工程穿越施工产生的应力损失；e)通过被保护对象(4)一侧土体应力损失的补偿，控制被保护对象(4)的位移，本发明可对被保护对象(4)的位移进行实时控制，可完全消除地下工程穿越施工影响，达到零位移非开挖施工，且造价低，质量可控，安全度、可靠度高。
