But in a few days, wait for the water to ease up, and plug it directly with earth rockIs there no way directly to seal the breach?
The width of 340 meters, so excited water, so a wide breach, the water is so deep, the boat stopped, so how long pile up? Where is the man standing? People have no place to stand. How can the pile driver be put into the wooden pile? Under such circumstances, even if there is a pile driver, what's the use? This is the changkai dike breach after there are no reasons for piling piling machine.Answer to your supplementary question:Closure of crevasse is a system engineering, it should include: pile, piling machine, operating platform, platform connection between the anchor pile, etc.. Not only one or two of them can be done.The following is the Liyang Ding Ding Mini piling equipment factory produced dragon dragon brand dam information, hoping to help answer your questions, if you do not see clearly, you can click on the map to see the original picture.First, dragon Ding card dam mapSorry, I'm only level one now. I can't upload pictures. If necessary, go to the website of the new tripod piling equipment factory in LiyangTwo, the Dragon Dingpai dam burst when the working drawing of pluggingThree, dragon card blocking effect after the burst dam closure graphWhen all of the pile are good, can seal the 90% water, finally burst all filled with debris, if there is enough manpower, also can be in front of the pile at the same time, immediately behind the embankment filling. Crevasse sealing is completed, will pull out all the repeated use of pile.
You can Liyang new micro piling equipment factory Ding directly copied to the Baidu searchIf necessary, I can forward it to you and can contact directly for details.
