Through the knowledge collation of the architectural knowledge column of this website, Zhong Da Consulting found that the tunnel safety management measures of construction enterprises mainly include:
There are many working procedures and many people in tunnel construction, which involve not only initiating explosive devices, but also aerial work and interchange work. Therefore, we must attach great importance to construction safety. On the premise that safety is benefit, safety is not only related to the vital interests of each of our construction workers, but also related to the purpose of our construction and the happiness of our family. Without security, there is nothing. Every construction worker and construction safety manager must put safety in the first place, strictly abide by safety construction regulations and safety operation procedures.
In order to help construction enterprises further understand the relevant contents of tunnel safety management, the basic situation of tunnel excavation safety technical measures includes:
1. Personnel participating in the construction must receive safety technology education and take safety examinations regularly. Only after passing the qualification can you work at your post.
2, into the tunnel construction personnel, must wear safety protection articles in accordance with the provisions, ZunZhangShouJi, obey the command, it is strictly prohibited to drink, sick people into the hole.
3. After the driller arrives at the work site, he should first check whether the working face is in a safe state, such as shotcrete and bolt support, and whether the top of the excavation face and two groups of bedrock are stable. If there are loose rocks, they should be supported or removed immediately.
4, drilling personnel before each working procedure operation, should check whether the pneumatic drill, feng shui pipe joint is firm, it is forbidden to dry drilling, drilling and charging.
5. When drilling with a pneumatic drill with a bracket, the bracket should be firmly placed. When drilling holes in ballast piles, attention should be paid to the stability of ballast to prevent people from falling and sliding during operation. It is forbidden to continue drilling in the residual eye.
6. For smooth blasting, explosives with low density, low strength, low detonation velocity or high explosive force should be selected, and other explosives should be modified.
7, hole blasting operations, must be unified command. During blasting, all personnel should be evacuated to a place free from harmful gas vibration and flying stones, with a safe distance of more than 200 meters.
8, after blasting, must go through ventilation and smoke exhaust, construction personnel are allowed to enter the working face, and the interval shall not be less than 15 minutes.
9. After blasting into the working face, inspectors should pay attention to the presence of misfire. When the misfire is found, the original blaster must deal with it according to the regulations; Whether there are residual explosives or detonators, whether there are loose rocks, and whether the bolting and shotcreting support is damaged or deformed.
10, drilling and charging are generally not allowed to work equally. In order to prevent the lighting from going out suddenly in the middle of the gun, the blaster should carry a flashlight.
1 1, when the working face is close to the breakthrough, we should strengthen the contact between the two ends and unify the command. When the distance between two working faces is eight times of the circulation size (not less than15m), stop working at one end, evacuate personnel and machines, and set warning signs at a safe distance.
12, the processing of blasting equipment is carried out in the processing room 50 meters away from the hole. Personnel who process blasting equipment and carry out blasting operations are prohibited from wearing chemical fiber clothing.
13. Construction personnel shall abide by the relevant regulations and standards of the state, the Ministry of Railways and the Ministry of Construction in addition to this regulation.
