Description
Technical field
The utility model is related to a kind of water sealing structure, and in particular to a kind of water-stop curtain.
Background technology
Tunneling and underground engineering is built in down town city at present, does not possess the condition of open-cut, and open cut substantially
Method early stage tear down and reconstruct it is costly, the duration because early stage tear down and reconstruct enforcement difficulty it is big can not pre-control.Relatively enriched in underground water and water level is higher
Downtown area construction bored tunnel, generally first use dewatering construction.And when the section of heavy traffic is constructed, due to
Scene does not possess precipitation condition, causes precipitation to carry out, and construction is difficult to advance.
In this regard, there is a kind of water sealing consolidation technology in the prior art, such as《Water rich strata shallow buried covered excavation water sealing consolidation technology》
A kind of water sealing structure of water rich strata construction for disclosing, its Full-face pouring that excavation face is carried out by the way of conduit slip casting,
To form complete injecting cement paste, carry out excavation face again after slip casting is finished draws digging.This kind of water-stop body has water-stagnating effect, favorably
In the development of construction.However, the water-stop body of this kind of structure needs the more slurries of consumption so that construction cost is higher.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome water-stop body in the prior art relatively costly, structure
Complicated defect, so as to provide a kind of water-stop curtain.
A kind of water-stop curtain, including：
First injecting cement paste, surround the outside for being arranged at and treating excavation face；
Second injecting cement paste, around the outside for being arranged at first injecting cement paste；
Non- injecting cement paste, is the original soil body, between first injecting cement paste and the second injecting cement paste, for buffering described
The soil deformation that one injecting cement paste and the second injecting cement paste are produced in slip casting.
Further, thickness of the thickness of first injecting cement paste less than second injecting cement paste.
Further, the thickness of second injecting cement paste is equal with the thickness of the non-injecting cement paste.
Further, the bottom of second injecting cement paste is provided with drainage arrangement, is oozed through second injecting cement paste for excluding
The water of leakage.
Further, the drainage arrangement is discharge outlet, and the discharge outlet is provided with double-edged fine-toothed comb.
Further, water plug is provided with the discharge outlet, for excluding the ponding in the discharge outlet.
Further, the water plug is vavuum pump, and the vavuum pump is provided with pipeline and leads to ground.
The utility model at least has advantages below relative to prior art：
1. the water-stop curtain that the utility model is provided, only including the first injecting cement paste and the second injecting cement paste, the second injecting cement paste is used
In sealing, the first injecting cement paste is used to reinforce the sealing performance of the second injecting cement paste, you can reach preferable water-stagnating effect, because
And slurries have been saved, reduce construction cost.
2. the utility model is additionally provided with non-injecting cement paste between the first injecting cement paste and the second injecting cement paste, because slip casting can be right
The soil body produces very big squeezing action, causes soil deformation；The setting of non-injecting cement paste has buffered the pressure produced during slip casting well
Power, reduces the deformation of the soil body.
3. the utility model is provided with drainage arrangement in the bottom of the second injecting cement paste, timely discharges through the second injecting cement paste seepage
Water, prevent to the first injecting cement paste produce water pressure, it is ensured that the water-less environment of construction.
Brief description of the drawings
In order to illustrate more clearly of the utility model specific embodiment or technical scheme of the prior art, below will be right
The accompanying drawing to be used needed for specific embodiment or description of the prior art is briefly described, it should be apparent that, describe below
In accompanying drawing be some implementation methods of the present utility model, for those of ordinary skill in the art, do not paying creativeness
On the premise of work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional view of the utility model water-stop curtain；
Description of reference numerals：
1. the second injecting cement paste；2. the first injecting cement paste；3. non-injecting cement paste；4. pumping equipment；5. excavation face is treated.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing.
Embodiment shown in Figure 1, a kind of water-stop curtain, including：First injecting cement paste 2, excavation face 5 is treated around being arranged at
Outside；Second injecting cement paste 1, around the outside for being arranged at first injecting cement paste 2；Non- injecting cement paste 3, is the original soil body, located at institute
State between the first injecting cement paste 2 and the second injecting cement paste 1, produced in slip casting for buffering the injecting cement paste 1 of first injecting cement paste 2 and second
Raw soil deformation.In this way, due to only setting the first injecting cement paste, the second injecting cement paste, therefore, slurries amount has been saved, reduce and apply
Work cost；Simultaneously as slip casting can produce very big squeezing action to the soil body, cause soil deformation；The setting of non-injecting cement paste is very
The good deformation for having buffered the pressure produced during slip casting, having reduced the soil body.
The thickness of first injecting cement paste 2 is less than the thickness of second injecting cement paste 1, the thickness of second injecting cement paste 1
Thickness with the non-injecting cement paste 3 is equal.In the present embodiment, the thickness of the first injecting cement paste 2 is the thickness of second injecting cement paste 1
Half；Treat the outermost of excavation face 5 because the second injecting cement paste is located at, therefore, its as main dash facility, what it bore
Hydraulic pressure is larger；And the first injecting cement paste 2 is located at the inner side of the second injecting cement paste 1, its Main Function is the water-stagnating effect to water-stop curtain
Further strengthen, the hydraulic pressure that it bears is smaller, therefore the thickness of the second injecting cement paste 1 is less than the first injecting cement paste 2.
The bottom of second injecting cement paste is provided with drainage arrangement 4, for excluding the water through the seepage of the second injecting cement paste 1；
In the present embodiment, the drainage arrangement 4 is discharge outlet, and the discharge outlet is provided with double-edged fine-toothed comb；For stopping that debris enter discharge outlet
It is interior, and then water plug is resulted in blockage；Water plug is provided with the discharge outlet, for excluding the product in the discharge outlet
Water；The setting of water plug causes that the ponding of discharge outlet is excluded quickly, it ensure that construction environment is anhydrous；Taken out described in excluding
Water installations are vavuum pump, and the vavuum pump is provided with pipeline and leads to ground.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of implementation method.It is right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need and unable to be exhaustive to all of implementation method.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
