The invention discloses a tunnel two-way out-of-hole construction method under the steep accumulation body slope condition, and the method comprises the steps: planning a single-side-wall section and a double-side-wall section on one side, close to an exit, of a tunnel hole body, and dividing the single-side-wall section and the double-side-wall section into a plurality of pilot tunnel blocks by arranging a supporting wall and a temporary inverted arch; and the pilot tunnel blocks are sequentially tunneled and communicated step by step in a bidirectional tunneling mode, anchor rods and meshes are installed on the inner side walls of the tunnel body on the corresponding pilot tunnel blocks, and concrete is sprayed to seal and reinforce the inner side walls of the tunnel body. The construction method is suitable for large-size tunnel portal exit construction under the steep accumulation body slope condition, a single-side-wall section is adopted to be converted into a double-side-wall section ...

The invention discloses a tunnel supporting construction structure under a loose accumulation body abrupt slope condition. The tunnel supporting construction structure comprises a passive protective net, a temporary protective fence plate and lateral micro piles. The passive protective net is installed at the slope crest of the loose accumulation type mountain, the temporary protective fence plate is installed at the portal of the tunnel body, the lateral micro piles are arranged between the loose accumulation type mountain and the tunnel body, the steel floral tubes are installed in a designated area above the tunnel body, and the bias supporting structure is further installed near the tunnel body. According to the bias supporting structure, the bias problem of the tunnel body can be effectively solved, the anchor cable type steel micro piles are arranged on the right side of the tunnel body and are parallel to the center line of the tunnel body and perpendicular to the earth surface contour ...
