Advanced reinforcement construction method of construction of water-rich weak surrounding rock tunnel

The invention relates to an advanced reinforcement construction method of construction of a water-rich weak surrounding rock tunnel. The advanced reinforcement construction method includes the following steps that S1, a contour line is excavated; S2, a tunnel face is sealed and first grouting reinforcement is carried out; S3, second grouting reinforcement is carried out; S4, an isolation layer anda waterproof layer are constructed; S5, a protection cement surface layer I is constructed; S6, a carbon fiber reinforced layer I is laid; S7, a steel arched frame is erected; S8, a protection cementlayer II is constructed; S9, a carbon fiber reinforced layer II is laid; and S10, a protection cement layer III is constructed. According to the advanced reinforcement construction method, the technology of combining secondary grouting is adopted for advanced reinforcement, and the technology of laying two layers of cement surface layers plus carbon fibers is adopted to form a reinforcing layer after the advanced reinforc
