Abstract
The invention discloses a two-cloth-one-membrane composite geo-membrane, which includes an upper geotextile layer, a middle thin membrane layer, and a lower geotextile layer, which are laminated together through a guide roller. The middle thin membrane layer is prepared from a high-molecular synthetic material. The upper geotextile layer and the lower geotextile layer are connected to each other, a bended part arranged at the connection position. A plurality of reinforcing ribs are symmetrically disposed on the inner side surfaces, which are pressed against the middle thin membrane layer, of the upper geotextile layer and the lower geotextile layer. The reinforcing ribs are in a long-bar-shaped cubic structure. The upper geotextile layer and the lower geotextile layer are connected to each other, thereby reducing production and manufacturing difficulty and cost. The middle thin membrane layer is pressed by means of the upper and lower reinforcing ribs so that displacement between the middle thin membrane layer and the upper and lower geotextile layers is avoided, thereby improving the tensile strength and anti-deformation capability of the composite geo-membrane.
Description
Technical field
The present invention relates to a kind of geomembrane, particularly relate to a kind of two cloth one membranous type composite geo-membranes.
Background technology
Composite geo-membrane is through baking oven Far-infrared Heating in the one or both sides of thin film, geotextiles and geomembrane is pressed onto through deflector roll and collectively forms composite geo-membrane, be divided into cloth one film and two cloth one films. Its wide cut 4～6m, weight is 200～1500g/m2, the physical and mechanical property index such as tension, anti tear, bursting is high. Composite geo-membrane is mainly used in antiseepage, can meet the civil engineering needs such as water conservancy, municipal administration, building, traffic, subway, tunnel. Select in macromolecular material and production technology due to it and with the addition of antiaging agent, therefore can use in unconventional temperature environment.
Existing two cloth one membranous type composite geo-membranes, its rete and be located thereon lower section layer of cloth and be easily generated displacement because of external force, cause existing tensile strength and the low deficiency of non-deformability.
Summary of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, it is provided that a kind of two cloth one membranous type composite geo-membranes.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of two cloth one membranous type composite geo-membranes, including through upper geotechnique's layer of cloth of deflector roll pressing, middle thin layer and lower geotechnique's layer of cloth, described middle thin layer is made up of high molecular synthetic material, described upper geotechnique's layer of cloth and lower geotechnique's layer of cloth are connected as a single entity, and be positioned at junction and be provided with bending section, described upper geotechnique's layer of cloth and lower geotechnique's layer of cloth are arranged in the medial surface symmetry offseted with thin layer and are equipped with some reinforcements, and described reinforcement is the cube structure of strip.
Further, described upper geotechnique's layer of cloth and lower geotechnique's layer of cloth are chopped fiber needle-punched geotextiles, and synthetic staple fibers needling nonwoven geotextiles is by carding after synthesising fibre shredding, utilizes pricker that fibre web is pierced through up and down repeatedly, makes fiber entanglement set mutually become cloth; Thickness is typically in more than 1mm, and porosity is high, and permeability is big, and anti-filter drainage performance is all good.
Further, described reinforcement is made up of high-density polyethylene material.
The invention has the beneficial effects as follows:
1, upper geotechnique's layer of cloth and lower geotechnique's layer of cloth are structure as a whole, and before pressing, reinforcement is positioned at homonymy, reduces and manufactures difficulty and cost.
2, by being equipped with a plurality of reinforcement at upper geotechnique's layer of cloth and lower geotechnique's layer of cloth medial surface symmetry, strengthen geotechnique's layer of cloth and the structural strength of lower geotechnique's layer of cloth on the one hand, make middle thin layer through the extruding of levels reinforcement on the other hand, not easily produce displacement with upper and lower geotechnique's layer of cloth, thus improve the overall tensile strength of composite geo-membrane and non-deformability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
Two cloth one membranous type composite geo-membranes described in the present embodiment, as shown in Figure 1, including through upper geotechnique's layer of cloth 1 of deflector roll pressing, middle thin layer 2 and lower geotechnique's layer of cloth 4, described middle thin layer 2 is made up of high molecular synthetic material, described upper geotechnique's layer of cloth 1 and lower geotechnique's layer of cloth 4 are connected as a single entity, and be positioned at junction and be provided with bending section 5, described upper geotechnique's layer of cloth 1 and lower geotechnique's layer of cloth 4 are arranged in the medial surface symmetry offseted with thin layer 2 and are equipped with some reinforcements 3, described reinforcement 3 is made up of high-density polyethylene material, the cube structure in strip.
Upper geotechnique's layer of cloth 1 and lower geotechnique's layer of cloth 4 are chopped fiber needle-punched geotextiles, and synthetic staple fibers needling nonwoven geotextiles is by carding after synthesising fibre shredding, utilizes pricker that fibre web is pierced through up and down repeatedly, makes fiber entanglement set mutually become cloth; Thickness is typically in more than 1mm, and porosity is high, and permeability is big, and anti-filter drainage performance is all good.
The operation principle of the present invention is:
By being arranged in the medial surface symmetry offseted with thin layer 2 be equipped with a plurality of reinforcement 3 at upper geotechnique's layer of cloth 1 and lower geotechnique's layer of cloth 4, strengthen geotechnique's layer of cloth 1 and the structural strength of lower geotechnique's layer of cloth 4 on the one hand, make middle thin layer 2 through the extruding of levels reinforcement 3 on the other hand, not easily produce displacement with upper geotechnique's layer of cloth 1 and lower geotechnique's layer of cloth 4, thus improve the overall tensile strength of composite geo-membrane and non-deformability.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
