土方开挖技术交底（Earthwork excavation technology） Technical disclosure records Specific date Project name Zheng Dong new tube City Village resettlement district two three building engineering group 6# Ground and foundation engineering Project Name: Earthwork excavation Work content A, construction preparation: 1, the main equipment: sharp, flat shovel, hammer, trolleys, ladders, picks, crowbar, ruler, slope ruler, small line No. 20 wire etc.. 2, the operating conditions: (1) before excavation, (2) we should find out the underground pipelines and other obstacles, (3) and should be based on the requirements of the construction program, (4) will be within the construction area of the ground, underground obstructions removed and disposed of. (5) the position or location of buildings or structures of the control line (pile), (6) (7) standard size quasi level pile and foundation gray line, (8) must be tested qualified and finished pre screening procedures (9). (10) surface clean up (11), good drainage slope, (12) in the construction area (13) to dig the temporary drainage ditch. (14) night construction, (15) the process should be reasonable arrangements (16) to prevent wrong dig or overbreak. The construction site should be based on the need to install the lighting facilities (17) should be set clearly marked on the dangerous section (18) records. (19) the excavation is below the ground level (tank) trench, (20) on the basis of local engineering geological data, (21) to take measures to reduce the groundwater level, (22) to fall below the bottom surface of the 50cm excavation, and then excavation (23). Familiar with the drawings (24), (25) technical work. Two, operation process: 1, process: To determine the order and slope excavation cutting groove edge contour along the gray line stratified excavation Trim slot bottom cleaning Sure, the slope of the 2: (1) the natural moisture in soil, excavation of the foundation pit (groove) and trench excavation, when the specified depth does
