水下边坡防护设计与施工

实际工程中常遇到需要水下边坡防护的问题,为此,介绍两种新型的边坡防护方法——模袋混凝土边坡防护和铰接式水工垫防护。模袋混凝土技术采用织物模袋做软模具,通过混凝土泵将砂浆或混凝土充灌进模袋成型,起到护坡、护底、防渗等作用。铰接式水工垫是采用高性能、绿色混凝土制成形状一致的块体,块体之间通过特殊的连接形成一个整体,来抵抗水流的冲刷,块体之间允许适当的位移和变形,从而使该种铺面维护系统具有高度的地形适应性。

Design and Construction of Underwater Side Slope Protection

IIn the actual projects there is a problem of underwater side slope protection. Therefore, the paper introduces two kinds of new type side slope protection methods - side protection of molded sack concrete and protection of hinged hydraulic cushion. The molded sack of fabric is used as soft mold in molded sack concrete technology. Mortar or concrete are filled into the molded sacks to be formed by concrete pump so as to play the action of side protection, bottom protection and anti-seepage etc. The blocks with the same form are made of high performance and green concrete. These blocks are used for the hinged hydraulic cushion. An integral is formed by a special connection between blocks to resist the erosion of water flow. An appropriate displacement and deformation is allowed between blocks so that this kind of paving maintenance systems has high adaptability for the topography.
