Research on environmental protection in green and low-carbon construction of construction projects?

Abstract In order to effectively strengthen the ecological environment protection during the construction of construction projects, prevent ecological damage and environmental pollution, protect and improve the ecological environment around the project, and create a beautiful landscape that harmonizes the project and the natural environment, combined with the project construction In line with the actual work of environmental protection, we achieve civilized construction, pay attention to environmental protection, and protect the environment. This article puts forward its own opinions on environmental protection in the current green and low-carbon construction of construction projects.

1. Problem raised

With the rapid development of my country's economy, construction engineering The scale of construction continues to expand, and the waste gas, sewage, smoke, waste, etc. generated during construction and production have put tremendous pressure on the environment on which human beings live. Therefore, environmental protection issues have increasingly become an important issue in construction. Construction waste The processing and consumption of construction materials have also become a symbol of the level of construction engineering and quality management. During construction, we must pay attention to environmental protection issues, protect the environment, and reduce construction pollution.

2. What is green and low-carbon construction

Green and low-carbon construction refers to the scientific management and technological progress in engineering construction on the premise of ensuring quality, safety and other basic requirements. , construction activities that maximize resource conservation and reduce negative impacts on the environment. Achieving environmental protection includes energy saving, land saving, water saving, material saving and environmental protection.

3. The following points should be paid attention to in environmental protection in current construction projects

(1) Dust control at construction sites. Dust prevention measures for loose particulate matter: After masonry sand and other materials are brought into the site, they should be temporarily covered with dense mesh or tarpaulin to control the amount entering the site at one time. Dust-proof measures for cutting and drilling: When cutting wood with a tooth saw, set a sawdust baffle under the saw to allow the sawdust to settle inside and be recycled. Dust prevention measures for digesting lime: Lime should be stacked in open areas away from residential areas, crops, and flammable materials. Loading and unloading should not be carried out in strong winds. Loading and unloading should be carried out lightly and spread low, and plowing and rolling should be carried out in a timely manner. Sprinkle water frequently to reduce dust, and set up colored strips of cloth around the area. Reinforcement joints: Large-diameter steel bars are mechanically connected with straight threads to reduce atmospheric pollution from waste gas produced by welding. Sprinkling water and preventing dust: During normal temperature construction, a special person will be assigned to sprinkle water every day, pump the water in the sedimentation tank to the water sprinkler, and sprinkle it while walking. Vehicle transportation dust prevention: Ensure that garbage trucks, concrete mixer trucks, and large cargo transportation vehicles are in good operating condition and have clean surfaces. (2) Noise and vibration control. Specific measures to reduce noise: General equipment noise control: Steel bar processing machinery: The steel bars of the project are processed on site, and a steel bar processing shed is set up on site to minimize noise. Wood cutting noise control: Set up wood processing sheds at wood processing sites to minimize noise pollution. Concrete pump noise control: During structural construction, determine the location of the pump truck based on the actual conditions on site, arrange it in an open location away from sidewalks and other industrial areas, and use equipment with low noise. Concrete pouring: Try to arrange pouring during the day. Choose low-noise vibration equipment. (3) Exhaust gas emission control. (4) Light pollution control. Specific measures: Set up welding light booths: Set up light shading booths at the welding parts of steel structures to prevent strong light from affecting the area around the construction site. For the welding of plate steel bars, used formwork nails can be used to maintain the baffle. (5) Water pollution control. The sewage discharge at the construction site should meet the requirements of the national standard "Comprehensive Wastewater Discharge Standard" (GB8978-1996). Set up sedimentation tanks, grease traps and septic tanks. Specific measures: Rainwater: Rainwater is discharged into the municipal pipe network after passing through the sedimentation tank. Sewage discharge: flush toilets are provided in the office area. Set up a septic tank near the toilet. The sewage will settle in the septic tank and then be discharged into municipal pipes or arrange for a professional team to clean it. (6) Soil protection. Protect the surface environment and prevent soil erosion and loss. Bare soil caused by construction should be covered with sand and gravel or fast-growing grass seeds should be planted in time to reduce soil erosion; sedimentation tanks, septic tanks, etc. should not be blocked, leaked, or overflowed. Clean all kinds of sediments in the pond promptly. Toxic and hazardous wastes such as batteries, ink cartridges, paints, coatings, etc. should be recycled and handed over to qualified units for processing, and cannot be transported as construction waste; used batteries must be recycled, and the old batteries should be returned when receiving new batteries, and finally the project department Hand them over to the company for disposal to avoid contaminating soil and groundwater. (7) Classification and treatment of solid waste. Garbage is classified and processed, and wood and wooden boards among the recyclable materials are recycled and reused by plywood factories and paper mills.

Paper for non-archival documents is double-sided for printing or copying, and discarded paper is ultimately recycled and reused by paper mills along with other paper products. Recycling of scrap and unusable steel: Scrap steel collected during construction will be uniformly processed by the project department and sent to the steel plant for recycling. (8) Construction waste control. We must take the following measures in accordance with the principles of "reduction, resource utilization and harmlessness": Solid waste reduction: through reasonable cutting technical measures, accurate cutting, and minimizing construction waste. Implement management measures such as "cleaning up after work". At the end of each job, before submitting the process handover order, you are responsible for cleaning up the garbage in your own process. Make full use of floor mortar, concrete and other materials made from construction waste. Improve construction quality standards and reduce the generation of construction waste.

As the construction industry is booming today, our professionals should follow reality and formulate reasonable solutions to effectively solve the problem of environmental protection in construction projects and promote social civilization. and make their own contribution to progress.
