土方回填方案(国外英文资料)Special construction plan for land reclamationSoil requirements and water content control:The fill should meet the design requirement and ensure the strength and stability of the fill, if the design is not required, the following rules should be met:(1) gravel, sandy soil, and blasting slag (2/3 per layer), which can be used for packing under the surface.(2) a viscous soil that complies with the compacted requirements, which may be used for all layers of packing;(3) mud and silt soil, generally cannot be used as a filler, but in soft soil area, the treated water content in conformity with the requirements of the compaction can be used to fill in the secondary position.Fill the size of the soil water content, directly affect the quality of ramming (RCC), the test should be taken before ramming (RCC), in order to get conform to the requirements of the compactness under the condition of the optimal water content and the least ramming (or crush) times. If the water is too small, the compaction is not solid. If water is too large, it is easy to make rubber.The soil water content is usually held in the hand, and the ground is in the right place. When the water content is too large, the measures should be taken to loosen, air dry, air dry, refill the soil, mix in dry soil or other water-absorbing materials, etc. If the soil is dry, it should be wet in advance, and when it is water, it can also be used to increase compaction or use high power compaction.In the drying of the climate, it is necessary to accelerate the excavation of soil, soil, soil and compaction to reduce the loss of moisture in the soil.When the stuffing is gravel soil (sand and sand), the water should be wet thoroughly before crushing, to improve the compaction effect.2, the base of the foundation pit:(1) venue to backfill should be clear substrate garbage, grass, roots, excluding water, mud and debris in the foxholes, stagnant water and measures should be taken to prevent the surface into th
