| description | The invention relates to the technical field of stratum reinforcement, in particular to a tunnel top miscellaneous fill area cap-shaped reinforcement construction method which specifically comprises the steps that area division is conducted according to a tunnel top miscellaneous fill area; carrying out partition edge sealing on the divided areas; and grouting slurry is injected into the subareas after edge sealing. According to the reinforcing construction method, the reinforcing areas in the original area are arranged in a partitioned mode, grouting is carried out according to different reinforcing areas and different grouting liquid and grouting heights, meanwhile, partitioned edge sealing is carried out according to the strong reinforcing areas, the supporting capacity of the reinforcing body surrounding rock is further guaranteed, and therefore the working procedure is reasonably arranged, and the construction efficiency is improved. On the premise that normal excavation and support of the tunnel are not |
