Group hole grouting lifting control method under underwater condition
The invention provides an underwater condition group hole grouting lifting control method. The underwater condition group hole grouting lifting control method comprises the following steps that the maximum lifting force threshold value Fmax capable of being borne by rock mass cracks under the underwater condition is calculated; the rock mass fracture group grouting hole lifting force Fup is calculated; before grouting operation, the construction number of the grouting holes is adjusted according to the numerical value relation between Fmax and Fup, so that the total lifting force Fup'lt of the grouting holes is constructed while the cracks are penetrated; and Fmax. According to the underwater condition group hole grouting lifting control method, the construction number of grouting holes is adjusted according to the numerical value relation between Fmax and Fup, so that the total lifting force Fup'lt of the grouting holes is constructed while cracks are penetrated; precise control over grouting lifting is achieved, building damage caused by too large rock mass lifting can be avoided, the shutdown accident rate caused by lifting is greatly reduced, it is guaranteed that underwater grouting engineering is safely conducted, and meanwhile the construction period of the underwater grouting engineering is guaranteed.
本发明提供了一种水下条件群孔灌浆抬动控制方法，包括以下步骤：计算出水下条件岩体裂隙可承受的最大抬动力阈值Fmax；计算出岩体裂隙群体灌浆孔抬动力Fup；灌浆作业前，根据Fmax、Fup之间的数值大小关系来调整灌浆孔施工数量，使得穿过裂隙的同时，施工灌浆孔总抬动力Fup’
