Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, those of ordinary skill in the art obtained under not making creative work premise all other
Embodiment, broadly falls into the scope of protection of the invention.
In describing the invention, it is to be understood that term " perforate ", " on ", D score, " thickness ", " top ", " in ",
Indicating position or the position relationship such as " length ", " interior ", " surrounding ", be for only for ease of the description present invention and simplify description, and not
It is to indicate or imply that the assembly of indication or element must have specific orientation, with specific azimuth configuration and operation, the most not
It is understood that as limitation of the present invention.
As it is shown in figure 1, the invention provides a kind of composite air-permeable antiseepage geotechnical grid, including geotechnical grid cell board 1,
Connector 2 and Peng Run soil pad 3, geotechnical grid cell board 1 is mutually perpendicular to be staggered, adjacent four geotechnical grid cell boards 1 it
Between connected by connector 2, bentonite pad 3 is compounded in geotechnical grid cell board 1 and connector 2 top by bonding agent.
As in figure 2 it is shown, geotechnical grid cell board 1 is HDPE rectangular slab, its two ends have T-shaped connecting portion 101, are positioned at T-shaped
Connecting portion 101 one end has four screws.
As it is shown on figure 3, connector 2 includes rectangle fixture block 201, connect below fixture block 201 and have alignment pin 202, alignment pin 202
One end has tip, is used for inserting ground and positions during laying.
Fixture block 201 surrounding side all has a T-slot mouth 203, and T-slot mouth 203 cooperates with T-shaped connecting portion 101, position
Four screws are had on T-slot mouth 203 outer wall.During connection, the T-shaped connecting portion 101 of geotechnical grid cell board 1 is inserted connection
In the T-slot mouth 203 of part 2, it is bolted fixing, sound construction, easy for installation, meanwhile, can be by geotechnical grid limit
Edge arbitrarily increases geotechnical grid cell board 1 and connector 2, extends the length and width of whole geotechnical grid, and autgmentability is strong.
As illustrated in figures 4-5, bentonite pad 3 includes geotextile 301 and the sodium bentonite being filled in geotextile 301
Granulosa 302, in the ordinary course of things, bentonite particle is loose shape, good permeability, and expands when bentonite particle meets water,
Form it into uniform colloid system, under the effect of geotextile, make Peng Run soil be become orderly expansion from unordered, lasting
Imbibition result is to expand soil layer self to reach closely knit, thus has waterproof action, has the ventilation anti-seepage performance of excellence.
The upper and lower surface of geotextile 301 is respectively provided with the most corresponding junction point 303, and junction point 303 is arranged in arrays,
