The key measures for green construction technology are energy saving, material saving, water saving and land saving during construction,as well as protecting environment and guaranteeing professional health.
(Mainly includes energy saving, material saving, section land, water saving, etc);3Technological innovation. 4 Conservation and utilization of resources 4.1 Energy saving 1)The application of heat insulating material: the roof plate of basement uses asbestos cement insulation board,besides,extruded polystyrene insulation panels applied in the roof and outside wall.In addition,the proper utilization of plastic-steel windows with insulating glass can improve the energy-saving effect. 2)Lighting system adopts high efficiency fluorescent lamps and energy-saving lamps.
Temporary construction should be designed reasonable,in this way the windows permit light and air entering. 4.2 water saving 1)The use of unconventional water resources:during foundation pit dewatering period,constructors should maximize the utilization of groundwater for the sake of saving water resources.For example:washing the vehicle,spraying water for road,scrubbing the toilet, watering greening plant etc.However,we all know that in the reduction of municipal water does not mean we could use groundwater resources without restrain. 2)According to the specific circumstances,constructors draw up temporary water supply scheme which can meet construction requirements.In addition, water pipe network in accordance with water quantity is necessary for reducing pipe damage. 3)The production water and living water should be respectively measured during construction.Water-saving appliances,such as self-closing flushing valve and saving-water taps,applied in the living area,besides,professional
technicians are responsible for managing and repairing the equipment and everyone should establish the conscious of saving water.Moreover,sewage discharged into the municipal pipe after through the drainage ditch to the sedimentation tank for two times. 4)The volume of the structure of raft foundation and basement is large, which belongs to the construction of large volume concrete.While large volume concrete requirements relatively high construction technology,especially to prevent the stress crack caused by hydration heat of concrete.Therefore ,the maintenance method adopts spray-type watering combination of covering can not only control the concrete’s surface temperature, but also save water resources. 4.3 material saving 1)The application of high-strength bars technology:the main structure of the construction adopts HRB400 as far as possible,which uses resistance heating method for flash butt welding operation.Through practice this innovation has proved that it can save about
This technology bring about following social and economic benefits including simplicity of operator,high construction efficiency,reliable performance,which is the key technique of the ministry to promote green construction. 6.3Curing agent using in film faced concrete technology This special curing agent is a kind of water emulsion materials with non-toxic and tasteless,which can reduce the concrete maintenance costs owing to the easy operation and water retaining effect.The water retention rate is more than 90% after 8 hours,reducing the quantity of water consumed(the water used for the curing of concrete is 2-5 times than stirring ). 6.4As-cast-finish concrete construction technology In this construction,the bottom formworks of the cast-in-place plate are made of film faced waterproof template ,which take advantages of the width,light weight and smooth surface.It can not only reduce the installation and save the labor costs,but also reduce the process of plastering. 7 Summary
