Description

A kind of soil-slope reinforcement means
Technical field
The invention belongs to slope reinforcement, the engineering fields of restoration of the ecosystem, and in particular to a kind of soil-slope reinforcement means.
Background technology
Existing soil-slope protection is main to consider slope protection, slope greening.Side slope internal stability is reinforced and deep Layer sluices, and consideration is less, and slope surface is serious by rain drop erosion.Using traditional bank structure, slope stability is poor, and deformation is larger.
Invention content
The purpose of the present invention is to solve defects in the prior art, and slope stability can be ensured by providing one kind Reinforcement means.
In order to achieve the above object, a kind of soil-slope reinforcement means of the present invention, by setting drain hole and anchor in side slope Bar, slope surface setting grid beams, and planting plants progress slope soil consolidates in the grid of grid beams.
Include the following steps:
(1)Soil bolt reinforcing body is set:Edge is uniformly beaten perpendicular to side slope surface direction, on side slope surface into side slope If more anchor poles, then slip casting twice is carried out to Grouting Pipe of the binding on anchor pole;
(2)It constructs on side slope surface grid beams:In grid beams insertion slope surface, upper surface is equal with slope surface;
(3)Connect grid beams and anchor pole:Anchor pole is stretched out into one end of side slope and grid beams are welded;
(4)Drain hole is set:Drain hole is set into side slope at each grid of grid beams;
(5)Construction ecological slope protection structure:The planting plants in the grid of grid beams.
Wherein, the step(2)Middle grid beams include more transverse features beams and Duo Gen longitudinal directions feature beam;Transverse features beam It is vertically connected to form the grid beams with reticular structure with longitudinal feature beam;Transverse features beam is equipped with lateral drain tank;Longitudinal direction Feature beam is equipped with longitudinal drain tank;Lateral drain tank is connected with the longitudinal drain tank being connected on longitudinal feature beam;Drain hole Water outlet one end be located above corresponding lateral drain tank.Side slope deep layer draining is carried out, and let out using lateral by drain hole Sink, longitudinal drain tank flow fast through water, prevent flow is excessive from causing soil erosion.
Transverse features beam and longitudinal feature beam use reinforced concrete structure;Anchor pole stretches out bank protection slope surface one end and carries out 90 ° It is L-shaped after bending, it is connected with the main reinforcement of grid beams.
Lateral drain tank, longitudinal drain tank protrude slope surface and set outward, are connected to form reticular structure;The bottom of lateral drain tank Portion is equipped with weeper.Trickle irrigation is carried out by the plant of weeper downwards.
Step(4)It is middle setting drain hole the specific steps are:In each grid element center of grid beams, in the horizontal direction to side slope Interior punching sets pvc pipe in hole, forms drain hole;Pvc pipe stretches into one end in side slope equipped with filtration, and the other end is stretched Go out the water outlet that slope surface forms above-mentioned drain hole.
The filtration of pvc pipe one end includes non-woven geotextile, metal mesh and sandstone filtering layer;Non-woven geotextile closing is set on One end of pvc pipe, metal mesh are coated on the outside of the non-woven geotextile, sandstone filtering layer be set on non-woven geotextile and metal mesh it Between.Soil layer filtering is carried out using filtration, only plays deep layer drain function.
Step(5)Middle plant uses the plant of the root prosperity suitable for local growth, and can arrange in pairs or groups in different grids The plant of different colours plays the role of ornamental beautify the environment.
Carrying out step(1)Anchor pole set before, first slope surface is modified according to certain ratio of slope.
Meanwhile repair intercepting ditch in side slope top of the slope;In side slope slope foot, barricade and gutter are set.
The present invention has the following advantages compared with prior art:The present invention is by reinforcing, and to slope surface deep layer side slope Take measures preventing rain wash, while acts on side slope shallow layer reinforcement using plant root whisker water suction and plant transpiration, improves the soil body Shearing strength.Water concentration is discharged under slope foot in gutter using lateral drain tank and longitudinal drain tank, both reduces water pair Slope surface and vegetation are washed away, and can carry out trickle irrigation to plant by the weeper of lateral sluicing trench bottom.
The present invention realizes artificial reinforced side slope and is combined with biological bank protection, prevention soil and water loss, restores and improve ecology, Quadruple of beautifying the environment acts on.

Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, soil-slope reinforcement means of the present invention, is as follows:
(1)Slope surface is modified by certain ratio of slope(It is whole to slope surface equating according to the original slope of side slope).
(2)Adverse grade intercepting ditch 4 is repaiied in top of the slope.
(3)The anchor pole 1 of depth 5-15m under being set along vertical line of slope by design spacing 2.0-3.0m across sliding surface, Slip casing by pressure twice is carried out to Grouting Pipe of the binding on anchor pole, forms soil bolt reinforcing body.
(4)The construction grid beams 3 in slope surface:Grid beams 3 are embedded in slope surface, and upper surface is highly consistent with slope surface;With reference to figure 2, grid beams 3 include more transverse features beams 31 and Duo Gen longitudinal directions feature beam 32, and transverse features beam 31 and longitudinal feature beam 32 hang down Directly it is connected to form the grid beams with reticular structure.Transverse features beam and longitudinal feature beam use reinforced concrete structure.With reference to Fig. 4,31 lower end of transverse features beam are arranged in the prominent part of U-shaped lateral drain tank 33, longitudinal 32 left and right ends of feature beam difference outside slope surface Longitudinal drain tank 34 is arranged in the prominent part of outside slope surface, lateral drain tank 33 is connected with the longitudinal drain tank 34 being connected, and is formed netted Discharge structure.The thickness of longitudinal drain tank 34 is 5cm, inner width 10cm.With reference to Fig. 5, the thickness of lateral drain tank 33 For 5cm, inner width 20cm, the bottom of lateral drain tank 33 sets that there are one weepers 35 at interval of 50cm.
