Taping Over Different Ground Profiles

Taping Over Different Ground Profiles

Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

Pumped Concrete

Pumped Concrete

Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...

Area of Science:

Occupational Health
Ergonomics
Construction Safety

Background:

Overhead drilling in construction causes significant musculoskeletal strain.
Awkward postures and high forces lead to shoulder, neck, and back disorders.

Purpose of the Study:

To evaluate two intervention devices designed to reduce physical strain during overhead drilling.
To compare the effectiveness and usability of these devices against the conventional method.

Main Methods:

Fourteen construction workers performed overhead drilling tasks.
Two intervention devices (inverted drill press, foot lever) and the usual method were tested.
Participants provided ratings on fatigue and usability.

Main Results:

Intervention devices were rated as less fatiguing than the usual drilling method.
Usability ratings for the intervention devices were lower than the usual method.
Reduced fatigue indicates potential for improved workplace safety.

Conclusions:

Intervention devices show promise in reducing fatigue for overhead drilling tasks.
Further design modifications are needed to enhance usability and productivity.
Workplace safety devices require iterative field testing and refinement before implementation.
