The hottest southcar rotary drill opened the life

the CSR rotary drill opened the life channel in 2 hours. The 2-year-old child was saved.

China Construction Machinery information.

at about 19:00 on May 21, near a community of the space base in the southern suburbs of Xi'an, a two-year-old boy accidentally fell into an abandoned deep well with a diameter of only 40 cm and a depth of more than 30 meters

after receiving the report, after the analysis and comparison of the on-site command forces, the Shaanxi fire site command determined that two sets of rescue plans should be carried out at the same time: one plan is that the on-site excavator should continue to dig a big pit on one side. The second plan is to drill another shaft next to the well, drill to the same depth as the child, and then drill an inclined hole to carry out rescue. After the analysis and comparison of the on-site command forces, CSR rotary drilling rig was finally selected to participate in the rescue

when President Wang of Xi'an Jianshan engineering company learned the news, he immediately put down all his work, mobilized CSR tr180 rotary drilling rig to rush to the site, and discussed the best solution with the on-site headquarters

at 23:05 on the 21st, the plan has been determined. A rotary drilling rig is used to drill another shaft 2 meters next to the boy's falling shaft. The depth of the shaft is the same as that of the boy falling into the shaft. The shaft is manually lowered and the shaft wall is horizontally broken by professional equipment for rescue

president Wang said that the rotary drilling rig has short hole forming time, accurate alignment and high verticality. The rotary drill of CSR in my hand should have no problem drilling in 3 hours. Considering the heavy rain and the muddy and slippery ground, a distance of 2 meters is a safe and relatively short suitable choice

at 00:32 on the 22nd, the rotary drilling rig began to work. Wang Lun, a technician from Jianshan company, operates the rotary drilling rig. It is very important to ensure the verticality of the rig. Once there is a slight deviation above, if you go down more than 30 meters, the error may be very large, so it will also affect the safety of children

at 1:23 on the 22nd, the rotary drilling rig has reached a depth of 25 meters. According to the rescue plan, the rotary drilling rig will be driven into a depth of 33.5 meters underground, which is about 2 meters below the position of the trapped child. From this position, the rescuers will also learn to dig laterally and drag the trapped children out of the trapped position

at 1:40 on the 22nd, the rotary drilling rig is close to the depth of the child! The search and rescue officers and soldiers are on standby and waiting for the drill to dig a little deeper than the child's position

at 02:15 on the 22nd, the drilling operation of the rotary drilling rig has been completed, with a hole diameter of 1 meter and a depth of 35 meters, taking 1 hour and 43 minutes. The hole forming deviation is less than 30cm. The fire fighters have gone down the well to rescue. A thin firefighter went down to the well with equipment on his back, ready to use an electric drill to break down the well wall

3:57, the child has been trapped underground for nearly ten hours. A fire fighter has just risen from the underground to the ground, and no one knows the following situation until now. After the firefighter rose to the ground, another fire war development data diagnosis technician went down to the well with tools to continue the rescue work

at 6:28, the rotary drilling rig began to evacuate from the site and was ready to use manpower to pull the rescuers and children underground to the ground. The rescue workers on the ground shouted down to ask where the people below were, but they didn't get to the place where the child was trapped. Soon, there was a faint "here! Here!" Response of

after 18 hours of hard rescue by on-site rescue personnel, the child was successfully rescued and rushed to the hospital

in this rescue, CSR rotary drilling rig drilled a 35 meter deep shaft within 2 hours, and the verticality deviation was less than 30cm. It ensured the smooth progress of the rescue. Successfully saved the life of a 2-year-old boy

at the same time, CSR kindly reminded the majority of construction units: standardize the management of the construction process, set up fences, warning signs and other protective measures during construction, and prohibit non staff from entering the site. Care for society, we work together

special thanks to President Wang of Xi'an Jianshan engineering company for providing CSR tr180 rotary drilling rig and rescue plan
