Construction scheme of slurry block stone retaining wall;
(1) mortar masonry adopts mortar masonry method. Mortar consistency is 30-50 mm, when the temperature changes, make appropriate adjustments. Before laying mortar, the soil on the stone surface should be cleaned up and moistened with water, so that the surface can fully collect water, but no water remains. The thickness of mortar joint is generally 20-30 mm, and the formed masonry requires smoothness, stability, compactness and staggered joints.
2 The mixture ratio of masonry mortar shall be determined through trial matching, and reported to the supervisor for review before use. Because there are many construction sites, the masonry mortar is stirred by a 350L drum mixer at each masonry working face and transported by dump trucks. Mortar test blocks shall be reserved according to the specification requirements.
(3) When the concrete floor is used, in the process of concrete pouring, some exposed rubble should be buried according to the requirements of the specification, and the concrete floor should be chiseled and washed before laying.
(4) Layered mortar masonry, horizontal stone masonry, staggered joints from top to bottom, overlapping inside and outside, stable masonry, each layer in turn.
