The invention discloses a riverway ecological protection slope, and relates to the technical field of riverway nursing, the riverway ecological protection slope comprises a protection slope body which is sequentially arranged from the slope top to the slope toe, the protection slope body comprises a foundation supporting layer, an ecological structure layer and a vegetation community layer from inside to outside, and the ecological structure layer comprises a geotechnical composite material layer laid on the foundation supporting layer; the geotechnical composite material layer is of a three-dimensional net-shaped structure or a bag-type structure. Complex mechanical transmission, movable parts and sealing structures are completely omitted. The ecological niche complementary mixed planting mode of deep-rooted shrubs, shallow-rooted herbaceous plants and slope toe aquatic plants is adopted, the deep-rooted shrubs can enhance the deep stability of a slope body, the shallow-rooted herbaceous plants quickly cover a slope surface to reduce surface erosion, the aquatic plants are connected with a water and land ecological interface, and the deep-rooted shrubs, the shallow-rooted herbaceous plants and the water and land ecological interface cooperate to form a multi-layer and high-stability vegetation community; the water and soil conservation capacity of the bank slope is improved, diversified habitats are provided for animals and plants, and the natural ecological function of the river bank slope is restored.

The utility model provides electric film laying equipment applied to a high slope. The electric film laying equipment comprises a support body, a support fixing beam, support moving pulleys, support pulley limiting devices and a track support. The support fixing beam is fixedly connected with the support body, the equipment has obvious advantages in laying the geotechnical composite material on the high slope from top to bottom, after the equipment is assembled, the laying equipment can be moved through manual or mechanical traction, and the movement is convenient and fast; the to-be-lapped position of the geotechnical composite material is controlled through infrared, the placement position of equipment is accurately adjusted, and the laying precision of the subsequent geotechnical material is guaranteed; after the equipment is in place, the geotechnical composite material needing to be laid is placed on the rotating working wheel and connected with the positioning auxiliary movable rotating wheel, the switch system is started, the motor provides kinetic energy for the rotating working wheel, the geotechnical composite material is manually pulled downwards until laying is completed, operation and control are easy, the arrangement quality effect is remarkable, construction safety is guaranteed, and labor force is reduced.

A multi-directional drainage geocomposite (1, 10, 11, 12, 13) comprises at least two drainage structures (2, 3) with a surface extent which is greater than the thickness and which are shaped so as to define respective main conveying directions (H-H; K-K) of a fluid flow along the extent thereof. The drainage structures (2, 3) are adjacent to each other, with respective surfaces facing each other. They are further connected to each other in a stable manner so that at least two respective main directions are orientated differently with respect to each other.

The invention belongs to the technical field of geocomposites, and relates to an anti-damage composite flat filament with drainage and reinforcement functions and a preparation method and application thereof, the composite flat filament is a core-spun yarn, and the core yarn adopts a drainage yarn and a reinforcement yarn A; fibers of the drainage yarns are special-shaped cross-section fibers, and the covering yarns are high-modulus and high-strength flat yarns; the preparation method comprises the steps that drainage yarn and reinforced yarn A serve as core yarn, the drainage yarn and the reinforced yarn A are fed into an oval yarn guide tube with double notches at the same time, high-modulus and high-strength flat yarn serves as covering yarn, and the yarn is prepared through a full-computer yarn covering machine; according to the application, the anti-damage composite flat filaments with the drainage and reinforcement functions serve as weft insertion yarns, the reinforcement yarns B serve as warp insertion yarns, the warp insertion yarns and the weft insertion yarns are evenly laid according to the density of the warp insertion yarns and the density of the weft insertion yarns respectively, a biaxial warp knitting method is adopted, binding yarns are used for weaving forming, and the drainage and reinforcement geotextile is prepared. The composite flat filament is good in strength and not prone to damage, and the geotextile woven by the composite flat filament has drainage and reinforcement performance.

A shallow gas well for use at landfills having a gas-producing waste pile includes a lower geocomposite positioned over the gas-producing waste pile and a protective layer of soil positioned over the lower geocomposite. An upper geocomposite is positioned over the protective layer of soil such that the protective layer of soil is positioned between the lower and upper geocomposites. An impermeable geomembrane is positioned over the upper geocomposite and a shallow gas well collector is positioned within the protective layer of soil.

The invention relates to a geotechnical composite material which comprises two layers of geotechnical cloth and a geonet arranged between the two layers of geotechnical cloth. The geonet is made of fibers, such as glass fibers, where the fibers, such as glass fibers, have a polymer coating. The invention also relates to a method for preparing the geotechnical composite material, an asphalt pavement doped with the geotechnical composite material, and a construction method of the asphalt pavement.
