Brief Analysis of Slope Laying and Pressure Protection Method of Geotextile
The laying and pressure protection of the traditional inverted filtering layer of geotextile require close collaboration between man and ship,which causes the difficulty in coordination,the problems related to laying accuracy,pressure protection quality and efficiency.In response to short construction period,high requirements for laying,pressure protection and environmental protection,it is proposed to tie steel pipe or PVC pipe with geotextile,and then a diver provides assistance in laying geotextile.At the same time,it is proposed to use ton bags,interlocking sand bags or cover slope surface with sand and cohesive soil,which achieves the pressure protection of slope shoulder,surface and root,satisfies quality requirement,enhances the protection of inverted filtering layer of geotextile,reduces the damage caused by friction and erosion.During dredger-fill,the field observation results verify the applicability of the method,that is,it not only ensure the laying and pressure protection quality of geotextile filtering layer,but also avoid the loss of filling materials or the leakage of mud.
