If the distance of top plate to soft substrate is more than five meters or more, the setting position at the top of steel wire is from the downward 1.5m of top plate
To be suitable, and corner must have affluence, and steel wire is to increase to be attached between steel wire and side plate there are rich purpose
Add the bonding strength of steel wire Yu surrounding ore-rock.After the completion of steel wire binding, one layer of geotextiles are covered on the surface of steel wire,
Particularly geotextiles are equipped with close to the side in region to be filled in steel wire.Geotextiles, also known as geotextile, it is by synthesizing
Water penetration geosynthetics made of fiber is pierced or woven by needle, the purpose that geotextiles are arranged here is in order to subsequent
When keeping out filling slurry in region to be filled, water can be allowed to filter out, without allowing filling slurry to filter out.
The large rock mass or sharp objects that will be laid at mould bag 2 are cleaned, to prevent filling filling slurry rear mold into mould bag
Bag is punctured by object, so that filling slurry flows out.Tile first layer mould bag 21 in soft substrate after cleaning, then to mould bag
In fill up filling slurry, the water of filling slurry can overflow outward in mould bag, in order to which water to be discharged, can be catchmented with setting on the outside of stope
Water can be guided to storage area by collecting gutter 7 by ditch 7, be side of the barricade far from steel wire on the outside of stope, on the outside of stope with
Separated between region to be filled by barricade.Specifically, barricade determines barricade ruler with three width, height and thickness sizes
Very little, collecting gutter 7 is arranged along the width direction of barricade, and the water filtered out in mould bag is collected into collecting gutter as far as possible, then passes through
Diversion pipe or diversion trench discharge.
After the water discharge of filling slurry in mould bag, it will appear unsaturation in mould bag, at this moment continue to fill out into mould bag

After waiting filling slurry consolidation afterwards, the laying of third layer mould bag 23 is carried out.General entire barricade can pass through three layers of mould bag or four layers
Mould bag composition carries out the laying of the 4th layer of mould bag if the laying of third layer mould bag is not bonded with top plate also, until and top plate
It fits together.
Mould bag is successively laid with, and is because if once multilayer film bag while being laid with and being filled, when most rear mold bag
In filling slurry consolidation after, mould bag barricade can be presented a kind of both ends and stick up, the low shape in middle part so that mould bag barricade and top plate and
Side plate connection is not close, needs subsequent remedy.
And complete one layer of mould bag filling process after, then carry out next layer mould bag filling, until reach top plate because filling
The mobility of extender paste at the beginning, final mould bag and top plate and side plane contact face are close together, and keep out subsequent wait fill out
When filling the filling slurry filled in region, filling slurry will not be made to flow out from the junction of mould bag barricade and top plate and side plate.
In the present embodiment, it can be laid with one layer of mould bag in the soft substrate on the outside of stope, carry out filling material in mould bag
The filling of slurry, when can make in this way to area filling filling slurry to be filled, even if filling slurry is from the base in region to be filled
Bottom is corroded to the base lower portion on the outside of stope, as the blocking of mould bag will not leak.
After mould bag barricade is built, filling slurry can be filled into region to be filled.The advantages of mould bag barricade
It is: if traditional barricade is built in soft substrate, when the water in filling slurry erodes soft substrate, so that soft
Substrate softens, and traditional barricade will appear damage, and when the filling slurry flowed in region to be filled increases, traditional barricade may go out
Now collapse；And compared with traditional barricade, mould bag barricade can be built in soft substrate, because if soft substrate is by water erosion
Soften, that mould bag barricade can sink, and can block filling slurry in the same old way, and bottom edge and side are not in spillage
Mouthful, and top will appear the phenomenon that being detached from top plate, need subsequent filling, but not opposite area filling filling material to be filled
Slurry has an impact because only gap can occur on barricade top, and in region to be filled fill filling slurry be all from bottom to
On start to pour, finally can just reach top, can suspend during this period to region to be filled pour filling slurry, or using point
It criticizes to region to be filled and pours filling slurry, i.e., using first part filling slurry is poured to region to be filled, to the filling of this part
After slurry solidification, then to region to be filled pouring part filling slurry, until area filling to be filled is expired.Both modes are equal
The time in the gap between the filling of mould bag barricade and top plate can be given.In addition, filling filling slurry in mould bag is selected to form barricade,
It is that the moisture of filling slurry in mould bag can be made to overflow, without overflowing because mould bag has extraordinary dehydration property and block pulp
Filling slurry out, while the moisture of the filling slurry in region to be filled can also be spilled over to collecting gutter by geotextiles and mould bag,
And then it is discharged into storage area.
