Safe production and civilized construction measures?

Safety production is the top priority of the enterprise and is an important part of the work to ensure that the project is completed on time and with high quality. Civilized construction is the key to solving the problem of dirty, messy and poor construction sites. It is a powerful measure to ensure the completion of various production indicators, ensure safe production, ensure project quality, save materials, change the appearance of the construction site, and reduce project costs. Below are the sample essays I recommend for everyone, welcome to read.

3. Scaffolding system

The building uses double rows of steel pipe frames as protective frames, and dense-mesh safety nets are used for fully enclosed construction in both horizontal and vertical directions. Every other layer in the horizontal direction is covered with bamboo springboards or bamboo plywood, and a dense safety net is laid at the bottom to prevent high-altitude objects from falling vertically and garbage and dust from scattering in the sky. The beam-column structure adopts fastener-type scaffolding. Protective fences are erected at the "four entrances" of each floor and the periphery, and horizontal protective frames are erected at the entrances of the passages. ***Detailed scaffolding and protective frame erection plan***.

In order to strengthen the environmental management of the construction site and control the dust, noise, water pollution and other factors that affect the environment during the construction process, in accordance with the environmental protection regulations and standards promulgated by the country and Beijing, combined with this project department Based on the actual situation, construction environmental protection measures have been formulated:

1. Transportation vehicles on site can make large circles, all main roads have been hardened, other areas where materials are piled are covered with gravel and hardened, and full-time clean-up personnel are assigned to sprinkle water every day. Four inspections can be carried out according to weather conditions to suppress dust. Fine particles and flying materials entering the site are promptly stored in the warehouse. Transport vehicles entering and exiting the site must be flushed with circulating water to ensure that the environment near the site is not affected.

2. In order to prevent noise pollution during construction, the site must abide by the "Noise Limits for Construction Site Boundaries of the People's Republic of China" ***GB12523-90***. All construction equipment, electric saws, electric planers, etc. will be closed, and the operation time will be scheduled before 22.00 to minimize the impact of construction site noise on the lives of nearby residents. At the same time, we will do a good job in ideological work for local neighborhood committees, units, and the masses. Do noise testing twice a month. The outside of the outer scaffolding is covered with sound insulation protection nets. When loading and unloading materials, handle them with care and do not throw or pick them up randomly to avoid unnecessary noise. During construction, vibrating workers must master the position of the vibrating rods to minimize contact with the steel bars for a long time. touch.

3. Two closed garbage stations for construction and domestic use are set up on site. Construction waste is separated from domestic waste and is removed in time every day to ensure a clean site environment. Full-time cleaning personnel are set up on site to be responsible for daily tracking around the site. Clean and sprinkle water at any time to reduce dust.
