Description
Technical field
The present invention relates to a kind of civil engineering draining and handle material and production method thereof, especially relevant with high flow soil engineering composite drainage network and production method thereof.
Background technology
Civil engineerings such as refuse landfill usually, tunnel, highway and railway all need to carry out draining to be handled, and the draining processing requirements of this class engineering is: structure can keep very high plane handling capacity; Discharge structure has good resistance to compression; Can bear long-term heavy load; Discharge structure has enough shearing resistance stability.The material choice relation of drainage system is to the stable and success of engineering.At present, alternative adrainage material has two kinds: a kind of is natural sand or gravel adrainage material; Another kind is that flame sprays the composite earthwork composite drainage network in a narrow margin.Natural sand or gravel adrainage material may owing to the construction or the material instability can cause certain problem, and required engineering quantity is very big, the laying that surpasses the local material of certain angle in side slope just becomes very big problem, and the exploitation of sand and gravel simultaneously also can cause very big environmental disruption.Flame sprays compound soil engineering composite drainage network in a narrow margin; at first its fabric is owing to adopt the flame injection compound; usually can cause fabric to burn attenuation; the intensity of fabric is subjected to very big influence; the anti-filter buffer action of fabric reduces greatly; even may produce object and pierce through fabric and enter drainage channel; reduce the hydraulic conductivity of adrainage material, even stop up, the hydraulic conductivity of therefore general this kind material is lower; the stability of product itself is not high; and the fabric width of product own is narrower, is generally about 2m, and the lapping construction amount is bigger; loss in the engineering is big, and cost is higher.
Summary of the invention
The objective of the invention is deficiency at existing adrainage material existence, provide that a kind of drainage effect is good, safety factor is high, economic environmental protection, than having higher relatively hydraulic conductivity under the top load, take into account draining, isolation, instead filtered, reinforced multiple function, be applicable to the high flow soil engineering composite drainage network and the production method thereof of different application scenarios.
For achieving the above object, the present invention is achieved by the following technical solutions.High flow soil engineering composite drainage network, comprise geotextiles and geotechnological web-roll core, be compounded with one deck geotextiles at geotechnological web-roll core single or double, geotechnological web-roll core adopts two ribs or the staggered net structure of three ribs, and geotextiles is spun-bonded needle punched non-woven geotextile of PFY or long filament woven geotextile.
Described high flow soil engineering composite drainage network, the staggered cancellated geotechnological web-roll core of its pair rib comprise rib and rib down, last rib and the parallel separately distribution of following rib, and between rib and the following rib interlaced arrangement be connected.
Described high flow soil engineering composite drainage network, the staggered cancellated geotechnological web-roll core of its three rib comprises rib, following rib and middle guide groove supporting rib, last rib, rib and the parallel separately distribution of middle guide groove supporting rib down, middle guide groove supporting rib is located between rib and the following rib, and last rib is with following rib interlaced arrangement and be connected with middle guide groove supporting rib respectively.
The per 100 kilogram weights formula rate of the geotechnological web-roll core of described high flow soil engineering composite drainage network is: 97～98 kilograms of high density polyethylenes, 2～3 kilograms of carbon blacks.
A kind of method of producing high flow soil engineering composite drainage network is: earlier high density polyethylene, carbon black are mixed in proportion, under uniform temperature control, make two ribs or the staggered cancellated geotechnological web-roll core of three ribs by disposable extrusion way extrusion modling, one or both sides at geotechnological web-roll core adopt the compound or glue bond method of surperficial infrared heat again, the geotextiles of the anti-filter of compound one deck isolation.
The present invention compared with prior art has the following advantages.(1) be design science of the present invention, simple and reasonable for structure, it with have drain function respectively, the anti-materials with function of filtering is combined into one, making the construction becomes more simple, solved some special engineering problems.This high flow soil engineering composite drainage network has very high tensile strength and anti-compression properties, and staggered net structure has high rigidity, and rib can prevent that the geotextile embedding from causing drainage channel to stop up, and its drainability is fabulous, and stability is higher.It can select the compound or non-composite drainage network of high flow capacity of corresponding specification and structure according to the construction needs for use: 1, draining web-roll core.Only needing can be used for the civil works of single water; 2, the geosynthetics net of single face composite earthwork cloth only needing can be used for single face to isolate the civil works of anti-filter, draining; 3, the geosynthetics net of two-sided composite earthwork cloth can be used for the two-sided civil works that needs to isolate anti-filter, draining.This high flow soil engineering composite drainage network has been taken into account draining, isolation, has instead been filtered, reinforced multiple function, is applicable to different application scenarios.(2) be every index of the present invention generally than prior art product height, particularly on the hydraulic conductivity of the most important index of adrainage material, to exceed one times nearly.(3) be compared with prior art, what the present invention adopted is that the infrared rays heating is compound or viscose glue is compound, to geotextile and all not damages of geotechnological web-roll core, and the combined strength bination height, meets and above the industry standard requirement, does not influence hydraulic conductivity.(4) be that fabric width of the present invention arrives 4.0m～5.1m, exceed more than one times that the construction loss significantly reduces, and reduces cost than like product.(5) be the function that two rib net structure web-roll cores have double drainage, three rib net structure web-roll cores have the single slope drainage function of higher hydraulic conductivity.But geotechnique's web-roll core single or double employing infrared heat is compound or adopt the compound one deck of viscose glue as isolating anti-geotextiles of filtering.It with have drain function respectively, isolate anti-filter function, the reinforcement materials with function is combined into one, and greatly facilitates construction, has reduced cost.This high flow soil engineering composite drainage network has very high tensile strength and anti-compression properties, and staggered web-roll core rib can prevent that geotextile from embedding, and avoids drainage channel to stop up, and its drainability is fabulous.
Following table 1 is that high flow soil engineering composite drainage network of the present invention and general type product compare (is that the 5mm composite drainage network is an example with web-roll core thickness):
