【正文】 l floor and in depth. Within 3m of upper side of foundation pit, piling up soil, materials and parking machines are not allowed. Workers are forbidden to jump over the railing. Set up warning signs and red light marks during the pit construction Set up safety supervisor, check the soil horizontal displacement and surface subsidence at definite time. Notice the design, construction and supervision units in time if finding problems, solve the problems together. Excavator and other construction machines are forbidden to collide piles inside the pit during the excavation. Some excavators excavate on the same working surface, the space between each other should more than 10m。 If excavate on the different working platform, the spacing between upper and lower excavators should more than 30m. Workers outside the foundation pit should not throw rubbish inside the pit, when transfer the tools into the pit should be careful. People rest should be far away from the side pit. MD3 PROJECT 16 / 17 Construction machinery should obey orders。 all vehicles driving should be in accordance with prescribed routes strictly to prevent crash. People should be far away from the construction machinery if necessary. No people are allowed to stand within the radius of gyration of excavators or doing other work. Notice the operators and can get close to after allowing if necessary. When driving the excavators and transporting cars, should be careful with the electric line. Working under the electric line is not allowed。 If working at one side of electric line, the vertical and horizontal distance should not less than and 4~6m(110~220KV) Adequate lighting facilities should be necessary during the night working. Warning signs and guardrails should be set in the danger area. Vehicles paved road must be set during the rainy season. Do the drainage work to ensure the traffic safety. 2. Environmental protection or environmental health management measures. Measures to prevent dust and air pollution Earthwork constructed by qualified transportation units and signed a contract of carriage. Mark the pany environment requirement in the contract. Arrange workers to clean wheel at site entrance. And pact the soil in car or covered tightly. The highest point of transporting soil should not exceed car 50cm, the edge not higher than the car. Reserved backfill soil used in the project should adopt the spray coverage method to prevent dust. Lay the precast concrete panels on the construction pathway, set washing bay at exit position and arrange workers. Set a sprinkler on site and arrange worker to watering according to the onsite situation to prevent dust. Measure to prevent water pollution Set septic tank of temporary toilet, the polluted water passed through septic tank, after precipitation then discharged into municipal sewage pipeline. Measure to prevent noise a sound management system to control manmade noise。 Monitoring the implementation of the noise value Construction Site Noise MD3 PROJECT 17 / 17 Measurement Methods daytime earthwork construction phase does not exceed 75 decibels at night does not exceed 55 decibels, and should be tested often (6:00 to 22:00 at daytime, 22:00 to 6: 00 at night) Onsite sanitation management Set workers responsible for keeping the onsite clean and tidy. Ensure no water on site, the vehicles without the sediment out of the site. Every day arrange workers to clean the road. Arrange workers to clean the office area, ensure no water and rubbish。 Do the supervision and inspection work of construction site environmental protection. At the beginning, middle and end of each month check 1 time of environment work. For the existed problems, we should rectify and do the preventative work, and make records and archiving. 3. Measure to prevent disturbing This project is located near the FV hospital, to ensure the proper construction, minimize the impact on the surrounding office and living, the following measure should be formulated: Civilized construction should be promoted onsite, establish a sound management system to control manmade noise, minimize human loud noise, enhance consciousness of preventing noise of all workers. Contact with the relevant department at any time, Adopt their ments and proposal reasonably. We resolve the relevant construction process arrangement and workers operating problems at the production meeting. We should inspect the noise during the earthwork regularly to ensure the noise below the threshold. For the manmade noise management system establishment, particularly, human beating, shouting must be eliminated, minimize noise nuisance.
