Detailed description of the invention
Being that a kind of speed of application that this utility model provides is fast as shown in Figure 1 and Figure 2, good seepage-proof property, construction cost is relative
The relatively low compound impervious wall for water conservancy project coffering.Compound impervious wall include concrete cut body 1, soft have
Machine barrier film 2 and anti-seepage linkage 3, described concrete cut body 1 is positioned in the cubic metre of earth and stone basis 4 of bottom, institute
In weir, the soft organic barrier film 2 superposed landfill cofferdam body 5 stated, described anti-seepage linkage 3 is positioned at described soil
Cubic meter of stone basis 4 and the junction of weir, described landfill cofferdam body 5, described concrete cut body 1 is soft organic with described
Barrier film 2 is an entirety by the connection of described anti-seepage linkage 3 antiseepage.A set of containing antiseepage connection by arranging
The compound impervious wall of structure 3, owing to the concrete cut body 1 being positioned in the cubic metre of earth and stone basis 4 of bottom is with superposed
Soft organic barrier film 2 in weir, landfill cofferdam body 5 be by the connection of described anti-seepage linkage 3 antiseepage be one whole
Body, such that it is able to be effectively accomplished the purpose improving anti-seepage effect, and then reach to ensure the mesh of the safety of whole engineering simultaneously
's.
In reference prior art, composite geo-membrane is often as the technology of the impervious core of earth rock cofferdam, and the application's is soft
Organic barrier film 2 preferentially selects composite geo-membrane, and requires that cutting out folding forms according to design.In conjunction with prior art pour mixed
During solidifying soil cut-pff wall body, need to pour first pouring concrete gathering sill 6 in advance, and postorder needs pouring concrete block after employing
The impervious core that described composite geo-membrane is constituted is poured into feature together, anti-seepage linkage 3 described herein by 7
Just include first pouring concrete gathering sill 6, rear pouring concrete block 7 and soft organic antiseepage transition thin film 8, now described soft
Organic antiseepage transition thin film 8, it is of course possible to be composite geo-membrane, can also be the organic film of other tension antiseepage equally, institute
The first pouring concrete gathering sill 6 stated is one-body molded with described concrete cut body 1, described soft organic antiseepage transition
Thin film 8 is structure as a whole with described soft organic barrier film 2, and described first pouring concrete gathering sill 6 is soft with described
Organic antiseepage transition thin film 8 is an entirety by the connection of described rear pouring concrete block 7 antiseepage.So, due to described
Anti-seepage linkage 3 in contain first pouring concrete gathering sill 6 and the rear pouring concrete block 7 that must have, thus realize
The first pouring concrete gathering sill 6 at original concrete cut body 1 top reused with and after water in landfill cofferdam
Connecting of rear pouring concrete block 7 antiseepage in weir body 5 is the most overall cut-pff wall, removes elder generation's pouring concrete to reach to reduce
Gathering sill 6 working procedure, and again with described first pouring concrete gathering sill 6 as the mesh of a part for compound impervious wall
's.So, due in the work progress in cofferdam, it is not necessary to remove first pouring concrete gathering sill 6, and take full advantage of described elder generation
Pouring concrete gathering sill 6 constitutes described compound impervious wall, thus is possible not only to accelerate the construction speed in cofferdam, but also can
To effectively reduce the construction cost building described cofferdam, simultaneously as concrete cut body 1 is thin with soft organic antiseepage
Between film 2 be by the connection of described anti-seepage linkage 3 antiseepage be one overall, it is also possible to effective improve antiseepage effect
The best, reach to ensure the security purpose of whole engineering.
Further, due to described soft organic antiseepage transition thin film 8, i.e. composite geo-membrane quality is softer, in order to protect
Demonstrate,prove it to shape and when rear pouring concrete block 7, occur without big extruding dislocation even cannot be poured into described after water mixed
Solidifying earth mulch cap 7, anti-seepage linkage 3 described herein also includes setting bracket 9, described soft organic antiseepage transition thin film 8
The one end being positioned at junction be hook-shaped structure 10, described hook-shaped structure 10 is supported on described by described setting bracket 9
In rear pouring concrete block 7 in first pouring concrete gathering sill 6.Now, the preferred structure of described setting bracket 9 is by more than one piece M
The reinforcing bar of shape bends little frame 11 and constitutes, and makes the reinforcing bar described in each part bend little frame 11 along described first pouring concrete gathering sill 6
Groove is in the rear pouring concrete block 7 being distributed in this elder generation's pouring concrete gathering sill 6.So, both can ensure that composite geo-membrane
Soft organic antiseepage transition thin film 8 of quality forms the connection of hook-shaped structure 10 in described rear pouring concrete block 7, in case
Only pulled from rear pouring concrete block 7 easily when landfill cofferdam weir body 5 and pull out and lose connection.Meanwhile, in order to
Prevent above-mentioned situation to greatest extent, and when ensureing when at landfill cofferdam weir body 5 extruding within the specific limits not
Can go out to damage soft organic antiseepage transition thin film 8 of composite geo-membrane quality, in described soft organic antiseepage transition thin film 8 and institute
The transition position stating soft organic barrier film 2 is additionally provided with the telescopic joint 12 of folding.
According to the compound impervious wall of said structure, relend the construction method of weir, the cofferdam body used in mirror prior art, this
Application just can use following construction method to construct, and i.e. described construction method is completed by following sequence of construction, first
Smooth qualified cubic metre of earth and stone basis 4 pours first pouring concrete gathering sill 6, with this elder generation's pouring concrete gathering sill 6 is the most again
Foundation excavation concrete cut body pour groove, then described pour groove in pour described concrete cut this
Body 1, the composition surface dabbing more described first pouring concrete gathering sill 6 being connected with described rear pouring concrete block 7, and will
The most prefabricated setting bracket 9 is arranged in described first pouring concrete gathering sill 6, then described soft by hook-shaped structure 10
Matter organic antiseepage transition thin film 8 supports on described setting bracket 9, finally pours described rear pouring concrete block 7 maintenance
Qualified, complete the construction working of the most described compound impervious wall.Use above-mentioned construction method, both can save clear
Except the work step of first pouring concrete gathering sill 6, can ensure that the antiseepage of described compound impervious wall connects by the operation of dabbing again, reach
To accelerating efficiency of construction, improve the purpose of anti-seepage effect.According to the structure of the above-mentioned compound impervious wall that the application provides, now institute
The telescopic joint 12 stated uses the method simultaneously folded when the landfill cofferdam weir body 5 described in landfill.Meanwhile, according to construction
Practical situation, when underproof concrete is arranged at concrete cut body 1 top, at pouring concrete gathering sill first described in dabbing
Cut while 6 composition surfaces being connected with described rear pouring concrete block 7.As such, it is possible to ensure the application institute to greatest extent
The build guality of the compound impervious wall stated.
