Abstract
The utility model relates to a warp-knitted composite geotextile with great longitudinal strength, which consists of binder yarn, warp, weft and geotextile, wherein, the warp, the weft and the geotextile are composited together by the binder yarn; the warp is made from glass fiber and has a linear density of 4,000-4,800 tex and a warp density of 5-6 yarns/mesh; the weft is made from glass fiber and has a linear density of 1,500-1,700tex and a warp density of 1-3 yarns/mesh; and the linear density of the bunker yard is 200-230 dtex. In the embankment engineering that muck foundation is paved, the warp-knitted composite geotextile can be laid on the spiled muck foundation as the reinforcement layer to improve the bearing capacity and stability of the muck foundation, and the embankment engineering can be completed with sandbags directly laid on the reinforcement layer for reinforced slope.
Description
Technical field
The present invention relates to a kind of through compiling composite earthwork cloth.
Background technology
Enclose Hai Jiangang, fill at sea is to build one of important content of harbor work's journey.Building a harbour or extending harbor district needs marine fill approximately, if the seafloor foundation of the sea wall of building is the reasonable basis of sand base formula, embanking project is finished in the direct making fill of the sand that can be packed in bag.If seafloor foundation is a muck foundation, how to reach the stable of dykes and dams, the fill difficulty is just bigger.Up to the present, fill is to adopt " method that silt fill block stone is squeezed in explosion " on muck foundation, and it is slow that this method need consume a large amount of stone material construction speeds, and investment is big, and construction costs high-quality leak is difficult to control, and is bigger to the environment damage influence.
Through compiling composite earthwork cloth is to utilize through compiling lashing wire at warp, walk repeatedly between the fibrage of weft yarn and geotextiles, make geo-grid and geotextiles woollen yarn knitting be the material of one, both had high-tensile, the characteristics of low elongation, have the performance of geotextiles again concurrently, therefore can be used for reinforcement enhancing, isolating and protecting through compiling composite earthwork cloth.Through theoretical designing and calculating, if adopt longitudinal strength be not less than 240KN/m through compiling composite earthwork cloth, when being used for the embanking project of making muck foundation, can saving stone material and consume, solve the difficult problem of the uneven subsidence of packed sand fill, strengthen the stability of dykes and dams.But the present longitudinal strength through compiling composite earthwork cloth is difficult to meet above-mentioned requirements generally less than 100KN/m.
The utility model content
It is a kind of through compiling composite earthwork cloth that the utility model provides, and longitudinal strength is very high.
Described through compiling composite earthwork cloth, comprise bundled yarn, warp thread, weft yarn and geotextiles, by bundled yarn with warp thread and weft yarn, geotextiles is compound is one, described warp thread is a glass fibre, and line density is 4000-4800tex, and warp count is 5-6 root/order, weft yarn is a glass fibre, line density is 1500-1700tex, and weft count is 1-3 root/order, and the line density of bundled yarn is 200-230dtex.
Bundled yarn adopts high-strength polyester fibers, and this is the common practise of this area.
As preferred version of the present utility model, described geotextiles is a filament non-woven fabric.
As another preferred version of the present utility model, described grammes per square metre through compiling composite earthwork cloth is 1050-1310g/m
2
As improvement of the present utility model, describedly also be provided with dope layer through compiling the composite earthwork cloth surface.Described dope layer can be the mixture of modified pitch and adhesive, impregnated in the coating solution through compiling composite earthwork cloth by weaving gained, and oven dry obtains then.Modified pitch can be selected according to concrete engine request, generally can adopt conventional AH-70 bi tumenf orr oad.Described dipping, oven dry are this area conventional method.Temperature during oven dry is unsuitable too high, and general baking oven is divided into and is A, B, four zones of C, D, and temperature is set to 100 ℃, 105 ℃, 120 ℃, 130 ℃ respectively, and temperature is provided with too high meeting has damage to the intensity of product.
Longitudinal strength of the present utility model is higher than 240KN/m.When the utility model is used for the embanking project of making muck foundation, underwater operation by the sea, be laid on through inserting on the muck foundation of pulling processing as the reinforcement layer, improve the bearing capacity and the stability of muck foundation, direct reinforcement slope bag bag sand on the reinforcement layer, finish embanking project, be a muck foundation fill at sea new technology, new technology, new method, it has saved a large amount of stone materials and has consumed, and has filled up the put more energy into blank of material manufacturer of domestic big intensity, extra strength; Can effectively solve the great difficult problem of the uneven subsidence of packed sand fill, strengthen the stability of dykes and dams; Accomplish that the sea gets yarn and dash a bag fill, construction quality is under control and improves, and engineering can advance by multiple spot, has accelerated construction speed and has shortened the duration, has reduced construction costs; Help protecting society ecological simultaneously, improve social bad border quality.The utility model product has been successfully applied to Lianyun Harbour and has built harbor work's journey.
