The Application Study Of The Wall Grouting Behind Technique At Manage The Inclined Well Of Dafosi Coal Mine

A new realm that grouting technique to be the engineering technique is already the history of more than 100 years.It is an important applied technique of geotechnical engineering, its theories research development is quick very.But at move under condition of water carry on the inclined well(well tube, tunnel etc. the concrete structure) wall after still note the application study that grouting blocks up the water and manages the water to harm the aspect not mature.For promoting grouting technique betterly and ising a wall particularly to grouting technical development behind, and improve the safe homework condition of the mine and alleviate the mineral well to drain the pressure, contact the actual premise in the theories under carry on its application study's is necessary and meaningful.This text first according to the Dafosi coal mine actual engineering geology and the hydrology geology conditions, flow out the reason of water to carry on the analysis to the well tube; Then set out from the actual circumstance, in contrasting the excellent foundation for turn, grouting technique project to carry on blocking up the water to the well tube after making sure the wall; The next in order at start construction the spot carries on to injection material to experiment the research, controling the CS to strach coagulation time of the liquid and solid knot strength variety regulation, thus chose the spot the syrup liquid of the reasonable matches with the ratio and grouting parameter and grouting craft; Draw lessons from people of the past's experience and the engineering fulfillment again, carry on the research to the equipments kit, grouting the wall behind of seal the bore instrument, a liquid admixture instrument to carry on the improvement, become a set of kit equipments for suit; The end notes the well tube after transform monitor the technique to apply to the wall grouting behind construction in the safe control, passing to monitor the data to reflect the well wall to be subjected to the dint appearance, getting to the grouting process in the well wall transform the circumstance and it transforms the regulation, for the grouting result and the grouting engineering construction safety to provide the assurance.Engineering practice make it logical , which the wall grouting behind technique at manage the inclined well of Dafosi coal mine to flow out the water is feasible, the grouting result to prominence.
