Description

Reinforced plastic weeper drain

Technical field

The utility model relates to a kind of civil engineering adrainage material, refers to a kind of weeper drain especially.

Background technology

Chinese patent 00227008 and 00219661 all provides a kind of " water drainage plastics french drain material ", form by a draining filter core and the outside geotextiles filter membrane that wraps thereof, the draining filter core is made of some thermoplastic tow, be the random distribution of sponge gourd grain shape, it may be molded to square or cylindrical shape, because the filter core of this kind plastics french drain material is the plastics tow body that is the random distribution of sponge gourd grain shape, the internal clearance is big, surface area that can be permeable is also big, so there are good water permeability, the french drain that thermoplastic is made also to make product have good toughness and flexibility, random bonding mutually between the plastics tow of formation filter core, has certain anti-pressure ability, the deficiency that exists is: 1, as pure above-mentioned french drain insufficient rigidity of moulding goods, in the permanent load process, easy deformation influences drainability; 2, filter cloth is wrapped in the filter core outside, staves easily in the construction, influences filtering function, and on the other hand, in use, filter cloth stops up drain hole after being adhered to by foreign material, influences seepage speed; 3, use singlely, only be applicable to draining, can not waterproof, in the civil engineering, also need can draining again can antiseepage french drain.

Summary of the invention

The utility model is on the basis of background technology, by setting up rigidity liner skeleton to obtain enough rigidity in the filtering layer that constitutes at the plastics tow, filter cloth is overlying on outward on the rigidity liner skeleton, overcome the easily blocked situation of drain hole, also avoided simultaneously the damaging problem of filter cloth in the construction, the utility model also can be set up waterproofing course, make weeper drain can draining again can antiseepage, diversify, enlarge range of application.The utility model is achieved in that a kind of Reinforced plastic weeper drain, comprises the filtering layer that is sponge gourd grain shape lack of alignment that is made of the thermoplastic tow, it is characterized in that filtering layer is built-in with rigidity liner skeleton, and described rigidity liner skeleton is covered with filter cloth outward.Generally speaking, rigidity liner skeleton can be a metal spring, also can be other similar material, because of it has superpower anti-pressure ability, not yielding under long-term condition of loading, overcome the problem of simple plastic products rigidity deficiency, guarantee water source rapid osmotic discharging.From financial cost, the used filter cloth of the utility model is generally nonwoven fabric of long fibers, also can be other and similarly filter cloth, because filter cloth directly is wrapped in rigidity liner skeleton appearance, can filter and not stop up the filter drain hole to the foreign material in the infiltration, not influence seepage speed simultaneously again.The plastics tow surface that the utility model constitutes filtering layer can be smooth smooth, but better should be the dry tow of surface hair, because the dry tow of surface hair, also there is the space in its tie point place, more helps permeable.

Metal spring as rigidity liner skeleton, it can be one group, also can be two groups or two groups of above assemblys, the determining of group number requires to select according to the required size of construction and the pressure that bears, if rigidity liner skeleton is selected one group of spring, reinforcing rib then can be set with fixing and enhancing rigidity in the spring, if rigidity liner skeleton is many group metal springs, then be filled with the thermoplastic tow that is sponge gourd grain shape lack of alignment between groups of springs, to guarantee the spring marshalling, at interval evenly, the rigidity liner skeleton periphery that constitutes at many group springs wraps tightly one deck filter cloth, further the fixing metal spring is not loosening, guarantees that simultaneously the infiltration between spring is unobstructed.In order to prolong the application life of product, in the stable performance of the medium-term and long-term maintenance of engineering, prevent the erosion of acid, alkali etc., metal spring of the present utility model is through plastic antiseptic metal spring circle.

According to the different field requirement, the utility model can be made into different shape, as cylindrical shape, semicircle, square, rectangle, ellipse, change is circular or its combination etc.

If need can draining again can waterproof french drain, also can on the part outer peripheral face of french drain filtering layer, set up waterproofing course.

The specific embodiment

Embodiment 1, a kind of plastic-steel draining blind pipe, once plastic antiseptic, in be provided with outside the high duty metal spring (1) of reinforcing rib (6) and covered nonwoven fabric of long fibers (2), secure bond is cylindrical shape filtering layer (3) outside the nonwoven (2), filtering layer is the cylinder by the thermoplastic wire-beam forming, it is that random sponge gourd grain shape distributes that tow after the moulding distributes, and is formed with infiltration gap not of uniform size all around.This kind blind pipe can be realized omnibearing infiltration, can be used for the use of refuse landfill, Coal Stack Yard, engineering such as soft soil roadbed.

Embodiment 2, a kind of plastic-steel draining blind pipe, reference example 1, rigidity liner skeleton rearranges through plastic antiseptic high duty metal spring (1) equilateral triangle by three groups, the thermoplastic tow of the random distribution of filling between spring, the skin of whole liner skeleton covers nonwoven fabric of long fibers (2).This kind draining blind pipe has superpower crushing resistance.

Embodiment 3, a kind of semicircle single face Permeable blind pipe, by filtering layer (3), in establish reinforcing rib (6) non-corrosive metal (NCM) spring (1) at interval nonwoven (2) make, the top of filtering layer is rectangle, the bottom is semicircle, by the plastics wire-beam forming, tow be distributed as random sponge gourd grain shape, strong bond one splash guard (4) on the two sides of filtering layer and the semicircle bottom surface, the blind pipe of permeable three waterproof of this single face can thoroughly solve the constuction joint percolating water phenomenon in the continuous construction of various engineerings, prevent the not problem of enduring hardships of the rubber sealing rod (joint) that in the past adopted, guaranteed the engineering quality of owing property forever.

Embodiment 4; a kind of Reinforced plastic weeper drain; be sponge gourd grain shape by the random arranged tow distribution square or rectangle filtering layer (3) of the identical thread plastics of diameter; two sides are connected with the lonely shape of last lower plane; there are some infiltration holes not of uniform size at the four sides; the outer rigidity liner skeleton that covers filter cloth in the filtering layer (3) is made of four groups of non-corrosive metal (NCM) springs (1); four groups of springs pass through the filling of plastics tow; marshalling; at interval even non-loosening; this weeper drain with many group metal springs as the liner skeleton; have superpower load, not yielding under the situation of permanent load, omnibearing pervious function; strengthen infiltration ability and drainability, can be widely used in building; traffic; water conservancy; worker China Democratic National Construction Association; the underground water supply and drainage engineering of building projects such as environmental protection.
