Tips for construction safety in rainy season in Southeast Asia it is rainy all year round in Southeast Asia, especially in rainy season in other countries
. 
How to do a good job of prevention in advance is a common issue faced by all construction enterprises in this region
. 
Today we collect and sort out some super practical rainy season construction protection measures, let’s take a look together
.
1 rain prevention materials preparation (1) every construction site should have sufficient flood control equipment and materials, including raincoats, rain shoes, shovel, straw bags, water pumps, etc., so as to ensure the personnel equipment is neat, effective and effective
.
(2) Build necessary shelter, set up relevant health facilities, etc
.

.
Technical preparation (1) prepare the operation instruction for rainy season construction, which shall be strictly implemented as the mandatory specification document for rainy season construction
.
(2) Before the rainy season, conduct a comprehensive inspection, focusing on the flood control, waterlogging prevention, electric leakage prevention, lightning protection and gale prevention of temporary buildings, construction roads, drainage system and temporary power supply, and take protective measures in advance
.
3
.
Drainage measures at the construction site (1) during the construction in rainy season, the accumulated water shall be removed in time at the construction site, and the inspection of supports, scaffolds and earthwork shall be strengthened to prevent dumping and collapse
.
(2) Preventive measures shall be taken for the mechanical equipment and materials in the area where the flood may inundate, and the construction personnel shall be prepared for safe evacuation
.
(3) For projects that work in rainy season for a long time, rain proof shed shall be set up according to the conditions
.
Construction will be suspended in case of storm
.
4
.
Equipment protection and raw material storage (1) the mechanical and electrical equipment and its switch box shall be protected from rain and moisture, and the grounding protection device shall be installed
.
(2) To set up a warehouse, do a good job in the rain proof work of the warehouse and moisture-proof work of the ground
.
Other materials shall be stacked according to their properties
.
(3) Rain proof measures shall be taken for raw materials and semi-finished products such as steel, wood, fly ash, cement, etc., which shall be placed in the shed or house, piled up and well ventilated, especially for the cement warehouse
.
5
.
Lightning protection (1) during outdoor construction, in case of lightning weather, the construction shall be suspended
.
Stay away from iron fence, overhead metal body, lakes, pools, isolated trees and other conductive objects, and find buildings (structures) with lightning protection in time
.
(2) During indoor construction, the design of air termination, down lead and grounding body of new buildings shall meet relevant protection requirements and pass the acceptance of lightning protection department
.

.
Foundation pit support (1) before the flood season, the excess spoil should be removed to reduce the pressure on the top of the slope
.
(2) After rain, the pit, groove, ditch slope and solid wall supporting structure shall be inspected in time, and special personnel shall be assigned to measure the deep foundation pit and observe the slope condition
.
If any dangerous signs such as cracks, looseness, broken supporting structure and walking are found on the slope, measures shall be taken immediately to solve them
.
(3) Strengthen the monitoring around the foundation pit, especially the projects adjacent to inland rivers or rivers and lakes should be equipped with sufficient submersible pumps and other drainage facilities to ensure timely drainage and prevent foundation pit collapse
.
7
.
Reinforcement works (1) when the reinforcement cage is stored, its lower part shall be padded empty, and the top and side parts shall be covered to prevent rain, fog, etc
.
from causing or causing rust
.
(2) The formed reinforcement cage shall be placed firmly on the solid and flat ground, and the stacking height shall not exceed 2m, so as to prevent deformation or collapse due to rain wash
.
(3) Welding and butt joint of steel bars are not allowed when it rains
.
If necessary, the construction work should be moved indoors
.
(4) Hoisting operation is strictly prohibited in Thunderstorm and gale (above level 6)
.
8
.
Scaffold Engineering (1) in case of heavy rain, high temperature, lightning strike, strong wind and other bad weather, stop scaffold erection and demolition
.
(2) After strong wind, heavy rain and other weather, organize personnel to check whether there is shaking and deformation of the scaffold
.
In case of inclination, sinking, loosening of wall connecting parts, displacement of joint connection, falling off of safety net, rope opening and other phenomena, timely handle them
.
(3) The scaffold must be erected according to the load calculation, and the management personnel must inspect it from time to time
.
If any potential safety hazard is found, it must be solved immediately
.
9
.
Concrete engineering (1) before concrete construction, check whether there is water in the formwork
.
If there is water, clean it before pouring concrete
.
(2) It is necessary to strengthen the measurement of moisture content of coarse and fine aggregate, pay attention to the change of slump, and adjust the water consumption in time
.
(3) Sufficient rainproof materials shall be prepared at the concrete pouring site
.
In case of heavy rain, concrete pouring shall be stopped immediately and the poured parts shall be covered in time
.
10
.
Bridge and culvert works (1) during the construction of bridge and culvert foundation works in rainy season, the rain water back irrigation measures shall be taken; the temporary water collecting well shall be set around the foundation pit to regularly remove the accumulated water, so as to ensure that the base will not be soaked, and the reinforcement will not be affected by moisture and corrosion, and the formwork and support will not be deformed and sunk
.
(2) After the completion of bridge foundation construction, the construction site at the bridge site shall be leveled
.
After the foundation pit is backfilled, temporary drainage facilities shall be provided in time to ensure that there is no ponding near the foundation pit
.
Remember to take safety measures before the storm.
