Ground-breaking workers should standardize safety operation analysis?

Digging, piling, drilling, ground anchor penetration depth is more than .5m, and ground stacking load is more than 5kg/㎡, which can generally be regarded as ground breaking operation. In fact, all ground operations that affect the safety of underground cables, pipelines and other facilities are included in the scope of ground-breaking operations. Such as greening plants, setting up large placards, publicizing galleries and discharging a large amount of sewage, which affect underground facilities; Use bulldozers, road rollers and other construction machinery to fill the soil or level the site; Stacking heavy objects on the site outside the regulations or transporting heavy materials in the boundary area outside the regular roads, and the total carrying weight of articles including means of transport is above the limit value. These ground-breaking operations may lead to safety accidents due to improper operation, so it is necessary to standardize the operation behavior of operators. Let's learn about the safety operation of ground-breaking operators.

Safety management requirements for ground-breaking operations

Ground-breaking operations should be handled with the Ground-breaking Safety Operation Certificate (hereinafter referred to as the Work Certificate), and ground-breaking operations are strictly prohibited without the Work Certificate. The Work Permit shall be countersigned by the relevant water, electricity, steam, technology, equipment, fire protection, safety, engineering and other departments of the unit, and shall be examined and approved by the competent department of ground-breaking operation of the unit. It is strictly forbidden to alter or lend the Work Permit, and it is not allowed to change the content of ground-breaking work, expand the scope of work or transfer the work site without authorization. Before operation, the person in charge of the project shall conduct safety education for the operators. Operators should dress according to regulations and wear appropriate personal protective equipment. The construction unit shall identify the hazards on the construction site, implement the safety measures one by one, check whether the tools and on-site supports are firm and intact, and handle the problems in time when found.

guardrails, cover plates and warning signs should be set up at the construction site for ground-breaking operation, and red lights should be hung at night to warn. When the ground is near the underground hidden facilities, appropriate tools should be used for excavation to avoid damaging the underground hidden facilities. If cables, pipelines and unrecognizable items are exposed in the ground breaking, the operation should be stopped immediately, properly protected and reported to the ground breaking for approval, and the ground breaking operation can be continued only after taking measures.

excavation points such as pits, troughs, wells and ditches

operations such as digging pits, troughs, wells and ditches should be strictly observed. Earthwork excavation shall be carried out from top to bottom, and the method of digging foundation is not allowed. The excavated soil stacking place and materials shall be at least .8m away from the edge of pits, troughs, wells and ditches, and the height shall not exceed 1.5m It is forbidden to block sewers and pits. When digging deep pits, grooves, wells and ditches, it is forbidden to dig holes in the soil wall for climbing. When using portable wooden ladders or portable metal ladders, it should comply with the Safety Requirements for Portable Wooden Ladders and Portable Metal Ladders. People are not allowed to stand or walk on the wall edge of pits, grooves and ditches.

when excavating, it is necessary to set up safety slope or solid wall support according to soil properties, humidity and excavation depth. The slopes of pits, grooves, wells and ditches or solid-wall supports shall be inspected at any time, especially after rain and snow and during thawing. If cracks and looseness are found in the slopes or abnormal danger signs such as broken or displaced supports, the work shall be stopped immediately and reliable safety measures shall be taken. When placing machinery, laying tracks and passing vehicles at the edges of pits, troughs, wells and ditches, an appropriate distance should be kept, and effective wall-fixing measures should be taken to ensure safety. When removing the solid wall support, it should be done from bottom to top. When replacing the support, the new one should be installed first, and then the old one should be removed.

In addition, the job site should be well ventilated, and the areas where toxic and harmful substances may exist should be monitored. When toxic and harmful gases are found, the operation should be stopped immediately, and the operation can only be started after reliable safety measures are taken.

when many people dig at the same time, the operations should be more than 2m apart to prevent tools from hurting people. When operators find any abnormality, they should leave the job site immediately. At the construction site, all personnel are not allowed to rest in grooves, wells and ditches. After the construction, backfill soil in time and restore the ground facilities.

I believe that after the above introduction, everyone has a certain understanding of the safety operation of ground-breaking workers. Welcome to visit Zhongda Consulting for more information.
