Multi-layer buffering debris flow protective retaining wall and construction method thereof
The invention discloses a multi-layer buffering debris flow protective retaining wall. The multi-layer buffering debris flow protective retaining wall comprises a concrete wall body, a metal energy dissipation buffering layer and a gabion buffering layer. The concrete wall body is provided with a slope facing face facing a mountain, the metal energy dissipation buffering layer is arranged on one side of the slope facing face of the concrete wall body, and the gabion buffering layer is arranged on the side, facing the mountain of the metal energy dissipation buffering layer. The metal energy dissipation buffering layer is composed of metal pipes. The gabion buffering layer is composed of metal wire cages. The invention further discloses a construction method of the protective retaining wall. The construction method comprises the steps that firstly, surveying and setting out are conducted, and earth excavation is conducted; the concrete wall body is constructed; and then the gabion buffer layer is installed, finally the metal energy dissipation buffering layer is installed, and the concrete wall body and the buffering layers are fixed to each other. The multi-layer buffering debris flow protective retaining wall has the advantages that the metal energy dissipation buffering layer and the gabion buffering layer consume impact energy of debris flow through self-structure deformation, and the service life of the concrete wall body is prolonged advantageously; and the buffering layers and the concrete wall body are constructed in a layered mode, and installation, replacement and maintenance of the buffering layers are facilitated.
本发明公开了一种多层缓冲的泥石流防护挡墙，包括混凝土墙体、金属消能缓冲层和填石笼缓冲层。混凝土墙体设有朝向山体的迎坡面，金属消能缓冲层设于混凝土墙体的迎坡面一侧，填石笼缓冲层设于金属消能缓冲层朝向山体一侧。金属消能缓冲层由金属管构成；填石笼缓冲层由金属丝笼构成。本发明还公开了该防护挡墙的建造方法。首先测量放线、土方开挖；接着建造混凝土墙体；再安装填石笼缓冲层，最后安装金属消能缓冲层，并且将混凝土墙体和缓冲层相互固定。本发明的优点是：金属消能缓冲层和填石笼缓冲层通过自身结构的变形消耗泥石流的冲击能量，有利于延长混凝土墙体的使用寿命；缓冲层与混凝土墙体分层建造，有利于缓冲层的安装、更换、维护。
