Specific embodiment
In order to illustrate the embodiments of the present invention more clearly with technical solution in the prior art, Detailed description of the invention will be compareed below
A specific embodiment of the invention.It should be evident that drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, and obtain other embodiments, the present invention is not restricted to the embodiment.
Referring to Fig. 1 to Fig. 3.A kind of basement post-pouring zone anti-seepage construction method of the embodiment of the present invention, it is described
It is used in the impermeable construction method of basement post-pouring zone and arrives a kind of impermeable structure of basement post-pouring zone, the basement post-pouring zone
Impermeable structure includes: post-cast strip 1, the wall 2 of 1 two sides of post-cast strip, is formed to pour mixed mud on the post-cast strip 1
The groove body 3 of reinforced concrete layer 4 is equipped with mixed mud bed course 5 on 3 inner wall of groove body, positioned at the mixed mud pad of 3 side wall of groove body
Layer 5 is equipped with waterproof steel plate 6, and the mixed mud bed course 5 positioned at 3 bottom of groove body is equipped with bottom plate 7, vertical on the bottom plate 7
Direction be equipped with multiple isolation boards 71 that water absorption layer 9 is accommodated to form accommodating cavity 8,6 side wall of waterproof steel plate and it is described every
It is abutted against from plate 71；The water absorption layer 9 is being additionally provided between the reinforced concrete layer 4 to inhale in the accommodating cavity 8
The isolation mesh 10 in gap is provided when water layer water swelling.
Supplementary explanation, the above-mentioned effect of mixed mud bed course 5 are filling 3 inner walls of groove body, and including but not limited to ash is laid bricks wall etc.
Form exists, and can also carry out brushing waterproof material after the completion of mixed mud bed course 5；It can brushing waterproof material on waterproof steel plate 6
Or it is nested with waterproofing membrane, it is fixed on the mixed mud bed course 5 on 3 two side walls of groove body by sealant etc., is further prevented
Water penetration；Structure in the accommodating cavity 8 of the bottom plate 7 and bottom plate 7 is installed on 3 bottom of groove body, and bottom again after the completion of can arranging
The isolation board 71 at 7 two end of plate is abutted against with waterproof steel plate 6, is in particular that the thickness of waterproof steel plate 6 can be according to 3 bottom of groove body
The width or length in portion are designed, so that waterproof steel plate 6 and bottom plate 7 can fully take up 3 bottom of groove body after being installed
Area can also generate certain extruding force to mixed mud bed course 5, guarantee integrally-built stability and waterproof performance.
Referring to Fig. 1 and Fig. 2.In this example, the wall 2 is also provided with use on the two sidewalls of post-cast strip 1
With the caulking groove 12 of laterally fixed sealing rod 11, the water suction with 11 general parallel orientation of sealing rod is also poured between two caulking grooves 12
Expanding layer 13 is equipped with isolation mesh 10 between the water-swellable layer 13 and the sealing rod 11, the purpose for the arrangement is that, setting
Sealing rod 11 can one end inlay and set in caulking groove 12, one end part is stretched out, to pour completion in entire reinforced concrete layer 4
Afterwards, water-swellable prevents water penetration；The water-swellable layer 13 of setting to sealing rod 11 tentatively water suction after, if there are also water it is residual
It stays, can further absorb to it prevents from leaking；The isolation mesh 10 of setting is inhaled to sealing rod 11 and water-swellable layer 13
Water expansion.
Supplementary explanation, above-mentioned water-swellable layer 13 are first to pour water-swellable layer 13 for specific by pouring molding
The reinforced concrete layer 4 of lower section after reaching suitable condition, then pours water-swellable layer 13, then carry out isolation mesh 10 and
The installation of sealing rod 11, then pouring reinforcement mixed mud 4 complete the structure arrangement of entire post-cast strip 1；The master of the water-swellable layer 13
Acting on is that can absorb water, by and the combination of sealing rod 11 completely effectively can tentatively solve infiltration problem, a kind of implementation
Mode can pour for quick lime, it is, of course, also possible to have other modes to realize identical function and effect.
Referring to Fig. 1 and Fig. 2.It can also include the cover board 14 to close the accommodating cavity 8 in this example, it is described
Cover board 14 is equipped with the through-hole 141 to be connected to the accommodating cavity 8, the purpose for the arrangement is that, the cover board 14 of setting can be closed
Accommodating cavity 8 guarantees that mixed mud excessive will not be flow in accommodating cavity 8 when pouring, it can also be ensured that in disposed outside water absorption layer 9
When other impurities entrance；The water that the through-hole 141 of setting can facilitate access for post-cast strip is flow in accommodating cavity 8, passes through water absorption layer 9
It absorbs water.
Referring to Fig. 2.In this example, a kind of embodiment of the water absorption layer 9 can be to include set on same accommodating cavity 8
Second water absorption layer 92 of the first water absorption layer 91 of interior close cover board 14 and close bottom plate 7, the purpose for the arrangement is that, it will absorb water
Layer 9 is set as two layers of composition and is located in same accommodating cavity 8, up and down arranges that effect is more to utilize different material and carry out moisture absorption
It is good.
In this example, 9 another embodiment of water absorption layer can be include the first water suction in the different accommodating cavities 8
Layer 91 and the second water absorption layer 92, the purpose for the arrangement is that: when the first water absorption layer 91 and 92 material of the second water absorption layer of arrangement can not
It is arranged apart not only to can achieve soaking effect when compatible, but also keep function more diversified.
In this example, a kind of embodiment of first water absorption layer 91 can be high hydroscopic resin layer；Second water absorption layer
A kind of 92 embodiments can be sealing rod layer, both materials can extremely effective absorption moisture, prevent from permeating.When
So, there can also be other modes to realize identical function and effect.
In this example, the sealing rod 11 can be water expandable waterstop or steel plate waterstop strip, according to use environment demand
And cost performance is selected, and guarantees effectively water suction.
In this example, the isolation mesh 10 can be set to multilayer steel wire or fast-easy closing-up net, the purpose done so
It is that isolation mesh 10 is that multilayer steel wire or fast-easy closing-up net form, isolation mesh 10 can be changed by the setting of the number of plies
Thickness, while there are gaps between multilayer steel wire, it is swollen after absorbing water convenient for sealing rod 11 or water absorption layer 9 or water-swellable layer 13
It is swollen.
In this example, it is also provided with waterproofing membrane (not shown) between the mixed mud bed course 5 and the bottom plate 7,
The purpose for the arrangement is that on mixed mud bed course 5 can coated with waterproof material or waterproofing membrane, can also be in the mixed mud of 3 bottom of groove body
The waterproofing membrane being arranged on bed course 5, doing so can make mixed mud bed course 5 further function as impermeable effect, can also prevent into
Enter the gap outflow to the water in post-cast strip 1 between waterproof steel plate 6 and isolation board 71.
In this example, the post-cast strip 1 can be poured using slightly expanded concrete, and being poured using microdilatancy mixed mud can be so as to
It is integrally-built firm after pouring molding.
Specific embodiments of the present invention are described in detail above.It should be appreciated that those skilled in the art are without wound
The property made labour, which according to the present invention can conceive, makes many modifications and variations.Therefore, all those skilled in the art
Present inventive concept passes through the available technical solution of logical analysis, reasoning, or a limited experiment in the prior art, all
It should be in protection scope determined by the claims.
