Scope

Scope: In order to standardize the engineering application of milling type equal-thickness cement-soil mixing walls, ensure advanced technology, reliable quality, economic rationality, and safety and environmental protection, this specification is formulated. This specification applies to the design, construction, quality inspection, and acceptance of milling type equal-thickness cement-soil mixing walls in foundation pit projects, soil reinforcement projects, and other isolation and seepage prevention projects. The design and construction of milling type equal-thickness cement-soil mixing walls should comprehensively consider factors such as the surrounding environment of the site, engineering geology and hydrogeology conditions, project characteristics and requirements, performance of construction machinery and equipment, material properties, and construction conditions. Emphasis should be placed on local experience, adaptation to local conditions, meticulous design, and fine construction. For the design, construction, and quality inspection and acceptance of milling type equal-thickness cement-soil mixing walls, in addition to complying with this specification, they shall also comply with the provisions of relevant national and local standards currently in force. Main technical contents: Milling type equal-thickness cement-soil mixing walls are suitable for fill soils, clay soils, silt and silt-like soils, sands, gravels, crushed rocks, extremely soft rocks, and soft rocks. The applicability of milling type equal-thickness cement-soil mixing walls in the following strata shall be determined through testing: 1. Humic soils, peat soils, organic soils, and contaminated soils; 2. Gravel soils with particle sizes greater than 200mm; 3. Rock strata with uniaxial saturated compressive strength greater than 15MPa; 4. Construction waste landfill soils and non-compacted fill soils. Milling type equal-thickness cement-soil mixing walls can be used for wate
