土石方工程施工要求及质量检测(国外英文资料) The hand is in a ball, the ground is scattered; Fill the area with drains to eliminate surface water. 4, the prevention measures that are not required for backfill soil compaction: When the soil is not suitable for the requirement, the earth shall be excavated and reclaimed or added to the material of solid backfill of lime and gravel. If the water content is too large, it can be loosened, dried, dried or mixed into dry soil. Use high power compaction. Prevention of landslide: keep the slope of the slope strong enough; Try to avoid too much static and dynamic load on the top. Quality requirements and testing methods: 1, flat ground: flat area of the slope and design difference should not exceed 0.1%, drain slope of the requirements of the design and not more than 0.05%, no request in design, for not less than 2% of the gradient in the direction of the drain. 2, the floor level allows for deviation: Surface elevation: manual cleaning up plus or minus 30MM, mechanical cleaning: plus or minus 50MM. Length, width (measured by the design center) should not be small; The surface of the slope of the slope of the slope is flat, not to be steep, and the construction of mechanical construction should not be steep. Ground, surface ground: horizontal elevation 0 ~ -50mm, the level is less than 20MM. The basic processing must conform to the design requirement or the specification of the construction specification. 4, backfill soil materials must conform to the requirements of the design or construction of the norms, such as gravel soils, sand blasting and stone slag particle size is not more than two-thirds of each floor shop to fill, can be used under the surface of packing; The water content complies with the viscous soil of the compacted requirement, and can be used as the packing of all layers. Silt and silt soil, which cannot be used for stuffing. 5, backfill soil must be in accordance with the provisions, layered ram pressure dense: mechanical layer
