A road structure reconstructed from large-scale independent underground garage and a construction method, which solves the problem of a newly constructed urban expressway passing through large underground space. The technical point is a construction method for the road structure reconstructed from large-scale independent underground garage, including the following steps: S100: segmentation for the garage, S200: preparation before construction: the materials and equipment required for construction are transported to the site, and the construction site is cleaned, S300: reconstruction for the front section, S400: reconstruction for the middle section, S500: reconstruction for the rear section. The inventiveness of the present disclosure is the application of segmentation construction, the front section is completely obsoleted, a transition section is provided at the middle, and the design of the rear section adopts a double-deck road, thus the original underground garage structure is fully utilized.

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.
