What should be paid attention to in the construction of concrete engineering

During the rainy season, it contacted the meteorological department during the construction period and made short-term weather forecast. Before pouring concrete, we should know the weather forecast in time, make full use of sunny days to organize construction, and rain when pouring concrete. We should take immediate measures to cover it with plastic cloth, so as to prevent fresh concrete from being washed by rainwater. Because of the engineering work must be concrete, should take measures to cover scaffolding.

Due to the use of commodity concrete, before the opening requirement of the commercial concrete mixing station according to the moisture content in sand and stone construction adjustment mix, strict control of commercial concrete slump, meet the requirements of construction period. Concrete is strictly forbidden in heavy rain.

When the concrete has not reached the initial setting, it should be covered with plastic cloth in time to prevent rain if it rains.

Mechanical and electrical equipment maintenance and material stacking:

For outdoor mechanical and electrical equipment, it is necessary to prevent rain and dampproof. The mechanical bolts and bearing parts should be constantly refueling and rotated to prevent rust. All electrical and mechanical equipment must be installed to prevent leakage protectors.

At the construction site of electromechanical equipment is relatively fixed, such as electric welding machine to take defensive canopy or motor with protective cover, do not allow the use of plastic bags, the electrical equipment must have reliable grounding measures for welding wire, cable, rubber line should check whether the aging and damage, unqualified glue line should be changed and repair, prevent leakage accident.

If all kinds of high and low voltage lines in the field should be checked in accordance with the requirements of safety operation regulations, ordinary rubber line and ordinary plastic line are not allowed to be towed anywhere.

The electrical and mechanical switches of various mechanical mechanical and electrical equipment should have rain proof and moisture-proof facilities.

After rain, check and inspect all kinds of electromechanical equipment and temporary lines. If there are signs of leakage and other signs, danger warning should be immediately marked and timely repaired and maintained, and there is a serious safety hazard to stop immediately.
