护坡砖的铺设方法
(1)水利护坡砖铺设之前,先对该工作面四周混凝土条带与面层反滤料间预留尺寸进行检测复核,确保在水利护坡砖铺设后与条带顶部为一平面;
(1) Before laying the hydraulic slope protection brick, check the reserved size between the concrete strip around the working face and the filter material of the surface layer to ensure that it is a plane with the top of the strip after laying the hydraulic slope protection brick.
(2)搬运时,应先从堤坡顶部条带处,在滤料往下铺设1-2道木板滑道,宽度不小于1.0m,然后依次将护坡砖顺木板滑道运至铺设面,即保证了滤料层面不被破坏,又减少了水工砖的损耗。
(2) When carrying, 1-2 wooden plank slides should be laid down from the top strips of the embankment slope with a width of not less than 1.0m, and then the slope protection bricks should be transported along the plank slideway to the paving surface in turn, which ensures that the filter layer is not destroyed and reduces the loss of hydraulic bricks.
(3)铺设平整度控制,应从横向和纵向两个平面进行挂线, 即在铺设水利护坡砖时,不可只挂纵线,从坡脚处逐排向上铺设, 同时要从坡顶先下再挂两道横向平面线,使排与排也保持同一平面,避免出现凸肚现象。
(3) Laying smoothness control should be carried out from both horizontal and vertical planes, that is, when laying hydraulic revetment bricks, not only vertical lines should be hung up, but also two horizontal lines should be hung up and down from the top of the slope, so that rows and rows can keep the same plane, so as to avoid convex belly phenomenon.
(4)边缝处理:每个护坡砖的工作面铺设完成后,与条带间不可避免存在不同程度的缝隙(尤其是弯段坡面),若边缝尺寸大于等于1/2砖时,则先用水工砖补修,再以1:1水泥砂浆填充收面;若边缝尺寸小于1/2砖时,则直接以1:1水泥砂浆填充收面即可。
(4) Side joint treatment: After each slope protection brick is laid, there will inevitably exist different mojuhdz.37ix.com.cnmojulys.37ix.com.cnresuomo.37ix.com.cnperesuomo.37ix.com.cnpvcmo.37ix.com.cn kongzhiqi.37ix.com.cndegrees of cracks between the working face and the strip (especially the curved section slope). If the size of the side joint is larger than or equal to 1/2 bricks, it will be repaired with hydraulic bricks first, and then filled with 1:1 cement mortar; if the size of the side joint is less than 1/2 bricks, it will be filled with 1:1 cement mortar directly.
