Producing concrete culverts is a manufacturing process that contains many safety hazards, so equipping yourself with preventive knowledge is very important.
1. What is a Concrete Culvert?
- Concrete is an artificial compound formed by bonding granular components (mainly: sand, stone, gravel…) with a binder (cement, additives, water, etc.)
- A concrete culvert refers to products such as round, box, or square culverts in general. It is a concrete structural component, including concrete and reinforcement steel, mainly used in drainage infrastructure projects.
- Precast concrete pipes are products manufactured at factories specializing in concrete structural components.
2. Concrete Culvert Production Process
- Steel cage fabrication is the process where workers use electric welding to connect steel rods together, forming a steel frame in the shape of the culvert.
- Mold preparation is the step where workers install the steel frame into the culvert mold. The mold components are assembled together, then moved to the location ready for concrete pouring.
- Concrete mixing is the process of preparing and blending components in the correct proportions to create concrete, which is then ready to be poured into the culvert mold.
- Centrifugal spinning follows after the concrete is poured into the culvert mold. This step removes air pockets and increases concrete density within the mold.
- Curing tank is a method of applying high-temperature steam under normal pressure. Concrete components become strong, solid, and durable through this process.
- Mold removal is the step of opening the mold after the concrete has reached sufficient hardness and quality standards.
- Transporting to the storage yard is the final step where finished culverts are moved using mechanical equipment to the concrete culvert storage area.
3. Hazards and Risks in Production
- Sparks from electric welding of the steel cage can cause fires if they contact flammable materials, and can also injure skin or eyes.
- Electrical equipment leakage may electrify exposed parts, handles, or cables if not properly insulated.
- Mechanical components of machines such as cranes, centrifuges, or other machinery can fall, crush, or entangle workers.
- Chemical additives in concrete can cause skin irritation, burns, or respiratory and internal organ damage.
- Prolonged use of bolt fastening machines can cause shoulder pain and joint injuries.
- Loud noise from high-powered industrial machines can lead to hearing loss.
4. Causes of Accidents in Production
- Poor organization, management, and labor arrangement in production
- No established procedures for operation, maintenance, or repair
- Design, planning, and layout of the project site
- Workers not physically or mentally fit
- Failure to conduct regular safety training for workers
- Workers’ awareness and behavior regarding occupational safety and hygiene
- Worksite and equipment that pose potential accident risks
- Work position relative to installed equipment
- Equipment or component failures causing accidents
- Lack of protective devices, warnings, instructions, or signs
- Using unverified equipment, materials, or chemicals
- Inadequate or improper personal protective equipment for workers
5. Safety Measures and Accident Prevention in Concrete Culvert Production
- Ensure workers are physically and mentally fit for work
- Workers must have sufficient expertise in operating and handling machinery
- Only use lifting equipment according to its specifications and technical characteristics
- Do not lift loads exceeding the equipment’s rated capacity
- Transport loads via lifting equipment only through factories, homes, or areas with people present
- Using two or more lifting devices for a single load is only allowed in special cases with approved safety solutions
- Load distribution per lifting device must not exceed rated capacity
- Ensure safe walkways for operators controlling equipment from the ground or platform
Important: Workers must receive occupational safety training before starting work
