Why is it important to pay attention to underground concealed works and obstacles during ground-breaking work?
When digging approaches underground concealed facilities, appropriate tools should be used to avoid damaging them. If cables, pipelines, or unidentified items are exposed during excavation, work must be stopped immediately; they should be properly protected and reported to the authority that approved the excavation. Work can resume only after appropriate measures have been taken.
During ground-breaking work, care must be taken to avoid damaging underground gas pipelines, which could lead to explosions or fires; damaged cables and optical fibers can also catch fire and cause electric shocks
Because it may affect the normal operation or use of underground equipment and facilities. First, dig the trench manually, and then choose mechanical excavation based on the actual conditions; in principle, mechanical excavation is not allowed within the factory.
With a grateful heart and a sense of thanks in one’s heart, no grand words are needed – just a simple wish.
Same as the opinion above; wait for a collection of Q&A
Carry a heart full of gratitude, keep a sense of thanks in your heart; no need for grand words, just a simple wish
Sharing materials of gratitude is an expression of the heart: Gratitude is a manifestation of emotions: Gratitude comes from a sincere heart
Trembling, as if walking on thin ice. Underground cables, optical fibers, gas pipelines, water supply pipes, etc. – careful handling ensures longevity.
The underground concealed works in hazardous chemical enterprises mainly include pipelines and cables laid underground. Pipelines include circulating water pipelines, fresh water pipelines, fire protection water pipelines, foam pipelines, sewage pipelines, and process medium pipelines, etc. Cables include power cables, lighting cables, communication cables, network optical fibers, etc. If construction begins without first investigating the possible existence of hidden structures underground at the site, it may cause damage to those hidden structures, leading to leaks of flammable and toxic substances and resulting in fires, explosions, and poisoning of people. This can also cause power outages as well as disruptions to networks and communications in the enterprise
Thank you to the teacher for sharing! I hope the teacher can compile these practical knowledge points related to production and construction into a single collection.
