Deepwater ground anchor grouting method
The invention discloses a deepwater ground anchor grouting method. The deepwater ground anchor grouting method comprises the following steps that S1, a water-proof casing pipe is installed in an anchor hole, a grout inlet pipe and a grout return pipe are fixed to a cable body, a grout stopping bag is installed on the cable body, an outlet of the grout inlet pipe is close to the bottom of the anchor hole, a lower opening of the grout return pipe is located below the grout stopping bag, an upper opening of the grout return pipe is located above a cable joint, and an underwater detector is installed over the upper opening of the grout return pipe; S2, an anchor cable is placed in the water-proof casing pipe and placed in the anchor hole; S3, grouting grout prepared on site is injected into the anchor hole through the grout inlet pipe; and S4, when the underwater detector monitors that grout starts to return from the upper opening of the grout return pipe, the theoretical grouting amount which is 0.6-1.4 times that of the grout is injected continuously, and the theoretical grouting amount is the theoretical grout amount needed for filling the anchor hole. According to the deepwater ground anchor grouting method, the requirements that an underwater anchoring grouting solidified body is early in strength, high in strength, micro-expanded, good in groutability, free of corrosion to steel strands and the like can be met while the compactness of the grout is guaranteed.
本发明公开了一种深水地锚注浆方法，包括以下步骤：S1、在锚孔中安装隔水套管，将进浆管、回浆管分别与索体固定，并在索体上安装止浆包，进浆管的出口临近所述锚孔底部，回浆管的下口位于所述止浆包下方，回浆管的上口位于索节上方，回浆管的上口正上方安装有水下探测器；S2、将锚索放入隔水套管内，将锚索下入锚孔内；S3、利用进浆管将现场配置的注浆浆液注入锚孔；S4、当水下探测器监测到回浆管上口开始返浆时，再继续注入0.6～1.4倍理论注浆量，理论注浆量为填满锚孔所需的理论浆液量。本发明保证浆液密实度的同时，可满足水下锚固注浆固化体早强、高强、微膨胀、可灌性好、对钢绞线不产生腐蚀等要求。
