Embodiment 2
The present embodiment provides the construction methods that one kind is lauched water-separating film sealing device on a large scale, include the following steps:
S100: assembling obtains multiple water proof film units, opencut earth's surface by water proof membrane body, rectangular card slot and T
Snap-gauge is assembled into water proof film unit；
S200: slotting is opened up in the subterranean zone that curtain need to be arranged and slip casting forms curtain, is specifically included: the depth of slotting
Degree selection 3m below water-bearing layer；
Step 1: after groove milling obtains current water proof film unit setting area, a water proof film unit is set to current water proof
Film unit is arranged inside area, and the frame in water proof film unit is placed in current water-separating film body regions, Xiang Dangqian water proof film unit
Frame in inject slurry；Because water proof film unit includes the joint area of 5000mm water-separating film body regions and a 200mm,
Therefore it can choose 5200mm as unit in charge of construction.The width of joint area is 500mm, and the width of water-separating film body regions is
100mm, therefore the width in most of region is all very little in slotting, greatly reduces the thickness of curtain, reduces note
Slurry amount.
Step 2: after groove milling obtains adjacent water proof film unit setting area, a water proof film unit is set to adjacent water proof
Film unit is arranged inside area, and the frame in water proof film unit is placed in adjacent water-separating film body regions, in current water proof film unit
T-type snap-gauge be embedded in the square card slot in adjacent water proof film unit formed seal nipple, the seal nipple, which is set to, currently to be connect
In head region；Slurry is injected into the frame of current water proof film unit；In this step, noise is copied by rectangular simultaneously using large-scale crane
It is put into slotting with T-type snap-gauge along earth's surface, the T-type snap-gauge of previous water proof film unit need to be included by rectangular card slot,
Due to size design, T-type snap-gauge can be close to rectangular card slot inner wall.In the process of water-separating film body regions slip casting are as follows: adopt
With two Grouting Pipes, slip casting is recycled back and forth according to same uniform velocity along slotting length direction, and two Grouting Pipe injection speeds are
0.4m3/min, two Grouting Pipes are adjacent to the rock inner wall of water-separating film body regions two sides, and the nozzle of two Grouting Pipes is in slurries
Ullage, between 0-0.2m.
Step 3: after using adjacent water proof film unit as current water proof film unit, return step two.
It preferably, in the step 2 further include injecting slurry in the joint area of Xiang Dangqian water proof film unit.Connector
The process of region slip casting are as follows: in T-type snap-gauge and the slip casting of the rectangular card slot other side, slip casting is up carried out from bottom, guarantees grouting port
The 0.5m or more below Starch Level always passes through the pressure and cohesive force of slurries in this way, guarantees the leakproofness of connector.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
