Protective structure for repairing unstable expansive soil side slope and construction method thereof
The invention relates to a protective structure for repairing an unstable expansive soil slope, and belongs to the field of geotechnical engineering. The protective structure is composed of a rigid protective system, a flexible protective system and a drainage system, wherein the rigid protective system comprises a repaired retaining wall formed after cracks of an original retaining wall are filled, a gravity retaining wall arranged in front of the repaired original retaining wall and a plurality of prestressed pipe piles inserted into a soil body at certain intervals, the flexible protection system comprises backfill soil, a waterproof geomembrane and vegetation, the backfill soil is used for replacing expansive soil and forming a plurality of slope and platform combinations in a layering mode, the waterproof geomembrane is laid on a backfill soil platform, and the vegetation is planted on the slope face of the backfill soil, and the drainage system comprises branch drainage ditches arranged on the backfill soil platform, a main drainage ditch arranged at the toe of the backfill soil slope, drainage capillary tubes installed in grooves formed in the surface of the backfill soil slope and water drainage pipes penetrating through the repair retaining wall and the gravity retaining wall, the drainage capillary tubes introduce water into the branch drainage ditches, and the water drainage pipes introduce water into the main drainage ditch. According to the protective structure, the construction period is shortened, and the manufacturing cost is reduced.
本发明涉及一种修复失稳膨胀土边坡的防护结构，属于岩土工程领域，由刚性防护系统、柔性防护系统和排水系统组成；其中刚性防护系统包括原挡土墙填补裂隙后形成的修复挡土墙、设置在修复的原挡土墙前的重力式挡土墙和多根间隔一定距离地插入土体内预应力管桩；柔性防护系统包括替换膨胀土并分层形成多个坡面与平台组合的回填土、铺设在回填土平台上的防水土工膜和种植在回填土坡面上的植被；排水系统包括设置在回填土平台上的分排水沟、设置在回填土坡脚的总排水沟、在回填土坡面开设的沟槽中安装的排水毛细管以及贯穿修复挡土墙和重力式挡土墙的泄水管，排水毛细管将水引入分排水沟，泄水管将水引入总排水沟。本发明有利于缩短工期，降低造价。
