Description

A kind of slope reinforcement structure and reinforcement means thereof

Technical field

The invention belongs to the ecological protection technology field, relate to a kind of slope reinforcement structure and reinforcement means thereof.

Background technology

Need excavation slope is taked the preventive works measure secondary disaster that occurs to prevent slope instability in the engineering constructions such as traffic, water conservancy and urban construction.Alien earth sparging is one of technical measures of commonly using, and key technology is that the organic substrate that will guarantee to sow grass seeds by duster on domatic is in stable state.Present technical scheme is many to be improved to reach to the performance of organic substrate own and makes it be in the effect of stable state on the body of slope, as utilizes green additive, cementing agent (cement, solidifying stone etc.) to make organic substrate have some strength and can growing plant.But such technical scheme lacks intensive consideration to the processing of slope drainage, and long-term groundwater erosion and top, slope runoff cause the domatic factors of instability still to exist, and causes that easily the Secondary Geological Hazards such as landslide, mud-rock flow occur.

Summary of the invention

The object of the invention is to overcome the defective that above-mentioned technology exists, a kind of slope reinforcement structure and reinforcement means thereof are provided, is a kind of slope reinforcement structure of Seed spraying technology, can effectively reduce domatic rain drop erosion and top, slope runoff to the erosion of organic substrate.

Its concrete technical scheme is:

A kind of slope reinforcement structure is provided with catchwater on Slope top, the domatic gutter that is provided with, and at the bottom of the slope gutter, and toe is provided with the piling and layout of stones retaining wall, and described catchwater adopts free stone masonry, and the catchwater bottom is the C15 concrete cushion.

Further preferred, the distance of described distance between drains on domatic is 3m.

A kind of reinforcement means of slope reinforcement structure comprises the following steps:

1) at first cleared up the side slope foreign material, 3m place, top grouts the gutter one with stone on the distance slope, reserves the rainwater diffluence pass, drainage grade 2～4%;

2) piling and layout of stones retaining wall construction at the bottom of the slope, the domatic 1～1.5m of retaining wall distance, with cement mortar, that stone material is cemented together, the high 6～10m of body of wall, filling soil in the piling and layout of stones space;

3) domatic galvanized wire mesh and rivet are mated formation, and wire gauze adopts the 14# galvanized wire, and mesh 5*5, anchor pole are Φ 18 screw-thread steels, the distance of the domatic maintenance of net pitch of fins 7cm;

4) soil, organic matter, vegetable seeds, fertilizer are packed into plant biological bag, and with plant biological bag with high outside and low outside form bond at the slope edges place;

The organic substrate that 5) will be mixed by soil, cement, organic matter, green additive, water-loss reducer is sowed grass seeds by duster on domatic with spray seeder, guarantees to sow grass seeds by duster thickness 〉=10cm;

6) slope drainage is constructed;

7) drainage construction at the bottom of the slope.

Compared with prior art, beneficial effect of the present invention is:

The runoff on top, slope has at utmost been collected in the setting of present technique mesoslope top catchwater, then makes it flow into gutter at the bottom of the slope by the slope drainage ditch, and top, the slope runoff that prevents from knowing clearly reaches the domatic purpose of protection to domatic washing away and corrode.

Description of drawings

Fig. 1 is the schematic diagram of slope reinforcement structure of the present invention.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in more detail.

A kind of slope reinforcement structure is provided with catchwater 1 on Slope top, the domatic gutter 2 that is provided with, and at the bottom of the slope, the gutter 3, and toe is provided with piling and layout of stones retaining wall 4, and described catchwater 1 adopts free stone masonry, and catchwater 1 bottom is the C15 concrete cushion.The distance at described 2 intervals, gutter on domatic is 3m.

A kind of reinforcement means of slope reinforcement structure comprises the following steps:

1) at first cleared up the side slope foreign material, 3m place, top grouts the gutter one with stone on the distance slope, reserves the rainwater diffluence pass, drainage grade 2～4%;

2) piling and layout of stones retaining wall construction at the bottom of the slope, the domatic 1～1.5m of retaining wall distance, with cement mortar, that stone material is cemented together, the high 6～10m of body of wall, filling soil in the piling and layout of stones space;

3) domatic galvanized wire mesh and rivet are mated formation, and wire gauze adopts the 14# galvanized wire, and mesh 5*5, anchor pole are Φ 18 screw-thread steels, the distance of the domatic maintenance of net pitch of fins 7cm;

4) soil, organic matter, vegetable seeds, fertilizer are packed into plant biological bag, and with plant biological bag with high outside and low outside form bond at the slope edges place;

The organic substrate that 5) will be mixed by soil, cement, organic matter, green additive, water-loss reducer is sowed grass seeds by duster on domatic with spray seeder, guarantees to sow grass seeds by duster thickness 〉=10cm;

6) slope drainage is constructed;

7) drainage construction at the bottom of the slope.

The above; only be the better specific embodiment of the present invention; protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses, the simple change of the technical scheme that can obtain apparently or equivalence are replaced and are all fallen within the scope of protection of the present invention.
