Blocking and protecting structure for inner and outer sheet-pile walls in abrupt slope terrain and construction method
The invention provides an abrupt slope terrain inner and outer pile-slab wall retaining and protecting structure which comprises an anti-slide pile body, the anti-slide pile body comprises multiple sets of inner anti-slide piles evenly distributed on the side close to a mountain and multiple sets of outer anti-slide piles evenly distributed on the side away from the mountain, and the multiple sets of inner anti-slide piles correspond to the multiple sets of outer anti-slide piles; the two sets of inter-pile baffles are located between the multiple sets of inner anti-slide piles and the multiple sets of outer anti-slide piles and abut against the multiple sets of inner anti-slide piles and the multiple sets of outer anti-slide piles correspondingly; the multiple sets of greening tables are evenly distributed between every two outer anti-slide piles, and at least two sets of greening tables are evenly distributed between every two outer anti-slide piles. Mountains on the two sides of a tunnel are supported through two rows of anti-slide piles, the stability of the mountains is guaranteed, excavation of the mountains is reduced, damage to the tunnel caused by slope instability is avoided, meanwhile, the anti-slide piles are excavated at multiple points, namely, a plurality of pile holes are excavated in the two sides of the mountains of the preset tunnel for pouring the anti-slide piles, and the mountains are supported in a multi-point plane forming mode. Therefore, disturbance damage to the slope is reduced, and the problem that in a conventional method, when a bias retaining wall is arranged on an abrupt slope on the outer side of a mountain, a pull groove is too large, and consequently the slope of the mountain is unstable is solved.
本发明提供了一种陡坡地形内外桩板墙挡护结构，包括抗滑桩本体，包括多组均布在靠近山体一侧的内抗滑桩，与多组均布在远离山体一侧的外抗滑桩，其中，多组内抗滑桩与多组外抗滑桩对应；桩间挡板，为两组，均位于多组内抗滑桩与多组外抗滑桩之间，且分别与多组内抗滑桩与多组外抗滑桩抵接；绿化台，为多组，且均布在两两外抗滑桩之间，两两外抗滑桩之间至少均布两组绿化台。通过两排抗滑桩对隧道两侧的山体进行支护，保证山体稳定性，减少山体开挖，避免边坡失稳对隧道造成毁坏，同时抗滑桩为多个点开挖，即在预设隧道的山体两侧挖掘多个桩孔进行浇筑抗滑桩，形成多点成面的形式对山体进行支护，以减小对边坡的扰动破坏，避免了常规做法中对山体外侧陡坡设置偏压挡墙时拉槽过大，导致山体边坡失稳的问题。
