Real-time control method for displacement of a protected object during pipe roofing method construction
The invention relates to a real-time control method for displacement of a protected object during pipe roofing method construction, and belongs to the field of pipe roofing method construction in thecivil engineering field. The method comprises the following steps of a) marking an isolation area (1) between a construction surface and the protected object (4); b) placing a bag (2) in a soil body in the isolation area (1); c) containing a fluid (3) in the bag (2); d) applying stress to the soil body on the outer side of the bag (2) through the fluid (3) in the bag (2) to compensate stress lossgenerated by construction; e) controlling the displacement of the protected object (4) by compensating the stress loss of the soil body on one side of the protected object (4); and f) replacing or partially replacing the fluid (3) in the bag (2) with solids. The displacement of the protected object (4) can be controlled in real time, construction influence can be completely eliminated, zero-displacement pipe roofing method construction is achieved, the cost is low, the quality is controllable, and the safety and reliability are high.
本发明涉及土木工程领域的管幕法施工领域中的一种管幕法施工时被保护对象位移实时控制方法，包括以下步骤：a)在施工面与被保护对象(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，f)用固体置换或部分置换袋子(2)内的流体(3)，本发明可对被保护对象(4)的位移进行实时控制，可完全消除施工影响，达到零位移管幕法施工，且造价低，质量可控，安全度、可靠度高。
