What is the stone cage net retaining wall? The stone cage net retaining wall is a new type of flexible retaining structure that fills the rock material with the particle size requirements into a flexible stone cage net to achieve a certain porosity and is layered by layer. It is mostly used in areas where water is washed by heavy winds and waves, and in riverside slope protection projects. The installation process of the stone cage net as the retaining wall 1. The masonry should be leveled. When laying the same level, it should be roughly flat. The height difference of adjacent stone cage nets should not be larger than 35cm. The stone filled on the top surface of the retaining wall should be higher than the cage of the stone cage net, and it must be dense. The small crushed stones are filled, and at the same time, the packings are uniformly filled into the respective boxes of the same layer. It is strictly forbidden to fill the single-grid nets at one time. Generally, the one-meter-high gabion net cage is preferably fed in four times. 2. Stone installation should be stable. The installation of the stone itself must be stable, with the face down, properly rocking or knocking to ensure it is stable. The volume and weight of the filling material should be not less than 1.70 tons/m3. Exposed filler stone, the surface should be leveled by artificial or mechanical masonry, and the stones should be overlapped with each other. After each layer of stone cage net is constructed, the geotextile should be hung on the back side, and then backfilled and compacted to ensure the stability of the stone cage net, and the design requirements must be met. After the construction of a layer of stone cage net, the site will be inspected first and then the second process can be carried out. 3, the connection should be reliable. The upper and lower left and right anchorage connections of the gabion net cage should be reliable. In particular, it is necessary to connect natural, and two 8-shaped pull-knots are added in the middle. 4, the wrong seam is very important. In the same masonry layer, adjacent stone cage nets shall be staggered and masonry, and there shall be no forward seams. The upper and lower adjacent stone cage nets should also be overlapped by mistake to avoid vertical joints. When carrying out the construction of the second layer of cages, the stacking of the upper and lower cages is carried out in accordance with the slope of the design drawings, and the upper cage and the lower mesh cover are tied and tied according to the design requirements, and The filling of the stone can be carried out only by fixing the position of the cage and the lower cabinet. 5, the cover has requirements. The gabion net cage cover must be carried out on the basis of the top stone blockage. The caps must be used to fix the adjacent joints at each end, and then tied, and the intersection of the cover and the cage frame should be Tied together 25cm apart.
