Tunnel support construction structure and method under loose accumulation body abrupt slope condition
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 line to serve as a supporting structure, the earthwork sliding force of the side slope lateral main sliding face can be effectively solved, and the influence of bias on the tunnel lining structure is reduced.
本发明公开了一种松散堆积体陡坡条件下的隧道支护施工结构，包括被动防护网、临时防护栏板和侧向微型桩；所述被动防护网安装松散堆积型山体的坡顶处，所述临时防护栏板安装在隧道本体的洞口处，所述侧向微型桩设置在松散堆积型山体与隧道本体之间，在隧道本体上方指定区域安装钢花管，在隧道本体附近还安装有偏压支护结构。本申请的偏压支护结构能有效解决隧道本体的偏压问题，通过于隧道本体右侧平行于隧道本体中线和垂直于地表等高线设置锚索型钢微型桩作为支挡结构，能有效解决边坡侧向主滑动面土方下滑力，减少偏压对隧道衬砌结构的影响。
