Abstract
Disclosed is a positioning grouting anchor rod suitable for preventing and controlling an engineering seepage damage and a construction method thereof. The positioning anchor rod comprises an anchor rod, a grouting guide pipe and a grouting pipe. When the seepage failure occurs in the project, a water pump can be connected with a drain pipe interface to realize water drainage, and at the same time, a positioner can be used for positioning grouting in the seepage failure area to improve the accuracy of grouting reinforcement. A drainage channel and a grouting channel involved in the present application are independent of each other and do not interfere with each other, and the drainage and grouting functions are combined on the basis of retaining the original supporting function of the anchor rod.
