套井回填技术方案(国外英文资料) Filling quality inspection: when backfill material, often should check the soil condition of earth material, water content and soil thickness meets the design requirements, and the compacted dry density, water content and permeability sampling test, reflect the filling quality of all kinds of representative data. 5, check the method For project quality control, sampling inspection for engineering construction system, including the self-check and sample review, to review the qualified rate as the evaluation standard of construction quality of the sample. The check method has: On-site inspection, construction process, each hole each sample a set of backfilling depth of 3 m, to test the water content, dry density at the scene, and can not meet the requirement to rework processing, complete, every 10 hole, each a set of 5 m sampling, in the field water content, dry density, permeability coefficient test. Sampling review: group headquarters quality inspection and random sampling along the axis sets of well location, determination of water content, dry density and permeability coefficient, the reasonable measure set well the quality of backfill. The proof of construction strength According to the amount of design drawings, clay sets of 4679.1 m, the well according to the previous construction experience and the project design, a drill footage every day 35 m, plan 2 months to complete, plan construction period beginning on March 26, 2012 to May 2012 at the end of month end. It also arranges for two excavators, one for excavators and one for agricultural tractors (5m3) for transporting clay from clay materials. Third, safety measures Construction electricity safety guarantee measures The temporary use of electricity in construction site shall be implemented strictly in accordance with the provisions of jgj6-88 of the construction site temporary electricity safety technology. The installation, repair and demolition of temporary electrical power projects sha
