Description

Bentonite cloth structure

Technical field

The utility model relates to a kind of bentonite cloth structure, relates in particular to a kind of hookup mechanism that is used in the waterproof cloth blanket with bentonite interlayer, and bentonite cloth can be fixed on the soil that is covered fast, and reduces the bentonite cloth structure of bentonite cloth slip probability in the work progress.

Background technology

Bentonite cloth (having another name called bentonite liner) has the characteristics that water expands automatically and repairs of meeting, be not afraid of and pierce through, thereby be laid on quite widely on the facilities such as artificial lake, reservoir, oil storage tank in order to as fluid-tight substrate, and also be used on the facilities such as landfill, treatment tank in order to prevent that sewage from oozing out polluted underground water.

General bentonite cloth system by at least two layers of geotextile (weaving cotton cloth or adhesive-bonded fabric) be clipped in bentonite layer between these two layers of fabrics and combine and make; Usually system uses woven cloth as the basalis that covers ground, and with the covering layer of adhesive-bonded fabric as the bentonite layer, and each layer rolls a synthetic liner with this bentonite cloth to utilize tailor's cushion to pass the fiber of adhesive-bonded fabric up and down, when bentonite cloth is met the puncture broken hole, bentonite can produce automatically and mend the close usefulness of doing, and reaches the effect that waterproof blocks water.

Be layered on the fortification such as artificial lake, reservoir, oil storage tank landfill or treatment tank when this bentonite cloth after, to cover earth more usually or sandy and stony soil comes ballast.Yet, when earth and sandstone are poured in this process on bentonite cloth, on the slope just; the landing from top to bottom of the earth of this covering and sandstone, thus bentonite cloth regular meeting is along with downslide, when perhaps bentonite cloth glides because of own wt; all must lay again, otherwise waterproof effect can't be reached.

To the problem that existing bentonite cloth can meet be described by Fig. 1.Label 1 refers to an existing bentonite cloth among Fig. 1, this bentonite cloth 1 is layered on the ground, pond of a reservoir 2, this reservoir 2 comprises at the bottom of the pond 21, embankment 22 and position be on the slope 23 between 21 at the bottom of this embankment 22 and this pond, and on smooth embankment 22, dig and establish a groove 24, after this bentonite cloth 1 is finished laying, the edge 11 of this bentonite cloth 1 is inserted in this groove 24, and covering sand 3 comes ballast on this bentonite cloth 1.As shown in the figure; when this sand 3 is poured on this bentonite cloth 1; bentonite cloth 1 regular meeting on the slope 23 is stressed and glide; and cause the bentonite cloth 1 on the embankment 22 also may slip in the reservoir 2; this bentonite cloth slides and can produce fold; and the surface that covers reservoir that can't be smooth makes and has the space between bentonite cloth and this surface, and then water just can be run off by the gap.

The utility model content

Main purpose of the present utility model is, do improvement at existing bentonite cloth in the problem that the place, slope glides easily, and provide a kind of bentonite cloth structure of strengthening laying soundness, its at the scene rapid construction have expansile water resistance gasket to form one, and can in the process that covers sandstone, not produce and glide, and then guarantee the waterproof effect of this bentonite cloth.

The utility model is to adopt following technological means to realize:

The utility model constitutes bentonite cloth structure and comprises one first surface layer, one second surface layer that is divided into bentonite cloth outermost both sides and be clipped in bentonite layer between this two surface layer, this bentonite cloth further comprises plural hookup mechanism, each hookup mechanism is to be combined in first surface layer of this bentonite cloth or the rope band on second surface layer, and this hookup mechanism can combine with a keeper that can insert in the soil, after making that this bentonite cloth is layered on the soil of a facility, can utilize this hookup mechanism to help location between this bentonite cloth and soil.

This first surface layer of described bentonite cloth and this second surface layer are made of geotextile (weaving cotton cloth or adhesive-bonded fabric).

But described rope band has stitch one first end and one second end together.

Described rope band is sewn to the ring on this first surface layer or second surface layer.

Described this first surface layer is made by woven cloth, and this rope band passes the litzendraht wire of this first surface layer, and have can be for two ends of stitch.

Described this keeper has first end that can insert in the soil and can supply second end of this hookup mechanism combination; First end of this keeper is preferably formed as needle-like, and this second end is preferably formed as hook-shaped or ring-type.

The utility model compared with prior art has following remarkable advantages and beneficial effect:

The bentonite cloth structure that the utility model constitutes not only at the scene rapid construction have expansile water resistance gasket to form one, and this bentonite cloth can or not influence by other external force in covering the process of sand and produce slip, covers on the abrupt slope can effectively prevent sliding stop even if be yet.
