Gravity type retaining wall Construction process and technical requirements
This data is the construction process and technical requirements of gravity retaining wall, 20 pages in total. Introduction: The retaining wall foundation shall be excavated by machinery in cooperation with manual work and by sections. The embankment retaining wall is generally constructed before the subgrade filling, but the height difference between the filling surface and the top surface of the wall shall not exceed 1.0m. The construction of cutting wall excavation shall be carried out after the foundation bearing capacity of the cutting retaining wall meets the requirements. When the embankment wall foundation is located on a slope along the line direction, the longitudinal slope of the base shall not be steeper than 5%. If it is steeper than 5%, the base shall be stepped. The foundation of cutting retaining wall shall be no less than 1.2 m below the road shoulder or side ditch platform, and no less than 0.2 m below the bottom of side ditch.
