The municipal education park (phase I) project is a comprehensive vocational education park integrating teaching, office, business and hotel, which is developed by a municipal education investment limited company and invested by an investment construction limited company.The project is located in Bishan Village, Maya Town, on the east side of the East Outer Ring Road of a city. The site is trapezoidal in shape and covers an area of 1007 mu. The original site is surrounded by hills, paddy fields and mountains.The project covers a large area, and there are many on-site transportation. The original paddy field surface dredging and mountain shrub surface clearing are heavy tasks, so many large-scale excavation and clearing machines must be organized for site leveling and transportation.To this end, the project department has specially set up a mechanical construction team to give unified command and work together to complete the site clearing and transportation work.
When crossing retaining walls or structures, construction shall be carried out before wall foundation, and effective measures shall be taken to protect existing pipelines;When the fire pipe of the water supply pipe crosses with the drainage pipe, the fire pipe of the water supply pipe bends to avoid collision.
During the handover and completion of the project, in addition to submitting inspection and acceptance data to the relevant departments of the owner as required, the project management department shall handle the handover and acceptance procedures for water supply and drainage and other sub divisional works to the owner until the owner is satisfied.
Most of the project is located in farmland. In order to facilitate the access of construction machinery and the transportation of materials, construction access roads are set along the construction line. The width of access roads is 4m. The structure adopts 20cm block stones and 20cm three slag.
The project tasks are scattered and distributed in a long strip along the line. After the construction team enters the site, first strengthen the team organization and construction management project monitoring;Secondly, we should do a good job in practical construction organization design, organize construction by sections, and arrange construction by parallel operation method.
