Abstract

The utility model relates to an ecological mat made of palm fiber, which comprises a plurality of three-dimensional space frames made of palm fiber, wherein one layer or a plurality of layers of polymer grids or glass fiber grids are arranged in the three-dimensional space frames which are mutually cemented to form a mat-shaped structure. The utility model has the strong function of earth protection under the conditions of steep slopes, bank slopes with the function of current scour, etc., and thus the utility model supports plant growth; on the other hand, a plurality of years later, when vegetation is retrieved and the root system gets strong, the palm fiber gradually used as natural material rots to become fertilizer with little environment pollution; at this time, the polymer grids or the glass fiber grids arranged in the palm mat still reinforce the anti-scour ability of the vegetation.

Description

Ecological pad

Technical field

The utility model relates to a kind of brown fiber ecological pad, relates in particular to a kind ofly to have an ecological pad that shore protection is protected sloping function by what monofilament and polymer grid or the gluing of glass grid formed.

Background technology

Need take artificial measures's shore protection Bao Po in abrupt slope and the place that the soil such as bank slope that the current scour effect is arranged are vulnerable to corrode.Modes such as the stone masonry bank protection of Cai Yonging, concrete revetment, grey scholar's bank protection were owing to can not support plant growing in the past, and cost is higher, just progressively can be supported the novel protective slope structure of plant growing to replace by geotechnical grid grassed slope, geotechnological gauze pad grassed slope etc. under non-extreme case.But also there are certain defective in geotechnical grid grassed slope and geotechnological gauze pad grassed slope, vegetation recovery needs the time more than 2 years usually, in the vegetation recovery process, its root system is shallow, branches and leaves are dense inadequately, need slop protection material to have stronger solid native effect, and the space, lattice chamber of geotechnical grid is bigger than normal, the three-D space structure of geotechnique's gauze pad is relatively poor, can not and have on the abrupt slope and play the strong soil effect of protecting under the environment such as bank slope of current scour effect, on the other hand, after vegetation recovery, its well developed root system, vegetation structure is reasonable, itself had very strong bank protection ability, only need carry out artificial appropriateness to it and strengthen getting final product, protection is excessive again at this moment for geotechnical grid and geotechnological gauze pad, cause the waste on the material, and in soil, imbed great variety of organic and can pollute the environment generation.

Summary of the invention

The utility model be overcome geotechnical grid and the above-mentioned defective of geotechnological gauze pad design a kind of simple in structure, shore protection is effective has an ecological pad that shore protection is protected sloping function by what monofilament and polymer grid or the gluing of glass grid formed.

The utility model provides a kind of ecological pad, it is characterized in that:

Described ecological pad is made of some three dimensions skeletons and one or more layers polymer grid or the glass grid in described three dimensions skeleton inside that brown fiber constitutes, and described three dimensions skeleton is glued mutually, constitutes the structure of similar pad.Palm fibre mat thickness and the big I of internal voids are adjusted as required, support plant growing after inserting soil.The glue that adopts is natural gum.

The utlity model has following advantage:

1. the utility model is arranged by brown fiber process is formed three dimensions, make the space palm fibre pad different more as required with thickness, after inserting soil extremely strong solid native effect is arranged, can and have under the mal-conditions such as bank slope of current scour effect on the abrupt slope and avoid soil losses, support plant growing.

2. in vegetation recovery early stage, root system is shallow, branches and leaves are dense inadequately, and the utility model can and have on the abrupt slope to play under the conditions such as bank slope of current scour effect and strongly protects the soil effect, thereby supports plant growing; On the other hand, vegetation recovers after the several years, and during well developed root system, brown fiber is as the natural materials fertilizer that rots gradually to become, environmental pollution is little, and is laid in the polymer grid of palm fibre pad inside or the effect that the glass grid still can play reinforcement vegetation erosion resistibility this moment.

3. lay simply efficiently, manually-operated does not need heavy mechanical equipment.

4. the used main material palm fibre of this utility model fiber is a natural materials, low price and pollution-free.

5. polymer grid or glass grid are not subjected to solar radiation owing to be laid in palm fibre pad inside, and long service life is treated still can play the effect of strengthening the vegetation erosion resistibility muchly after brown fiber rots.

Can with other protective slope structure flexible combination.

The specific embodiment

Brown fiber 1 is processed to form three dimensions arranges also glued one-tenth pad, laying one or more layers mesh in inside is polymer grid or the glass grid 2 of 1cm * 1cm, makes thick 5cm, the coiled material of wide 2m or sheet material.

On the abrupt slope with have that soil is easy to be etched under the mal-conditions such as bank slope of current scour effect, thereby plant can't be grown, utilize the utility model both can prevent erosion, but restore vegetation again.To plant the immature soil additive during installation and mix, make the dense mud that contains grass-seed, pour in the ecological pad, be fixed on abrupt slope or the bank slope with the timber 3 of living then with mortar pump with grass-seed with when ground surface soil.Plant immature soil additive and include water-loss reducer and multiple fertilizer, support the plant rudiment and the growth needs in 4 early stages, behind the plant survival, its root system can be tied in the soil below the ecological pad deeply.

The staggered band in the land and water that the current scour effect is arranged, also ecological pad can be bundled at the scene diameter is the 50cm volume, in the process of tying up, insert the table soil and the reed rhizome of living, with diameter is 4 centimetres, the willow bar alive that length is 90 centimetres is fixed on the waterside, then both can play the unrestrained shore protection effect that disappears, can recover the aquatic vegetation of the staggered band in land and water simultaneously again.

Claims

1. ecological pad, it is characterized in that: described ecological pad comprises some three dimensions skeletons that brown fiber constitutes, have one or more layers polymer grid or glass grid in described three dimensions skeleton inside, described three dimensions skeleton is glued mutually, constitutes the cushion structure.

2. ecological pad according to claim 1 is characterized in that: the thickness of described ecological pad and its internal voids size are adjustable.

3. ecological pad according to claim 1 is characterized in that: glued described brown fibre three-dimensional glue that adopt in the space is natural gum.
