Abstract

The invention belongs to a wall slope greening method. In the method, soil retaining plate fixing frames are built on two sides of a planting place, the fixing frames and the soil retaining plates are made of permanent building materials such as ceramic and concrete, N chutes, of which the height increases from the inside to the outside, are formed on the fixing frames, the width and thickness of the chutes are matched with those of the soil retaining plates to ensure that the soil retaining plates can be held right in the chutes, the gap between the two soil retaining plates is used as a planting trough, the soil retaining plates can retain the soil and moisture in the hollow wall from coming out and ensure the plants can absorb water and fertilizers in and below the planting trough and receive light above, and thus, the wall slope is greened normally and permanently.

Description

The method of on the wall slope, afforesting

Technical field the invention relates to a kind of method of afforesting on the wall slope.

Background technology plant will survive too busy to get away soil, moisture content, the main problem of wall slope plantation now are exactly not solve fixing soil how and not only water conservation but also be beneficial to the method for draining.Mainly there are the following problems for the method for wall slope plantation at present: (1) container and fixture are easily aging, burn into gets rusty, and single container water retention property is poor, and summer is drought easily, and potential safety hazard is arranged, and storm wind may blow off flowerpot to hurting sb.'s feelings on the ground; (2) container capacity is little, and nutrition is easily exhausted; (3) life-span weak point, the cost height is produced the mounting process complexity, is difficult to promote.

Summary of the invention the purpose of this invention is to provide a kind of method, and with equally simple on the ground, plant easily survives and diversification of varieties this method in greening on wall or the slope, and the life-span of greening is the same with building long, and cost is low, manageability.

Characteristics of the present invention are to depend on certain building or natural main body, as construction wall, enclosure wall pillar, parapet, inclined roof, road bank protection, lake, river embankment, abandoned mine, viaduct, light pole etc., fixedly breast boards is accumulated the purpose that soil is reached plantation on aforementioned body.Its concrete grammar is: (1) bottom and draining are handled, matrix bottom in the needs plantation is provided with drainage arrangement, outside on drainpipe, smearing then with cement mortar high in the slope on ground, leave N discharge outlet that is communicated with the bottom discharge device on the slope, ramp slope (being the angle of slope and vertical plane) is 15---75 degree.(2) the both sides fixed mount is installed, the fixed mount of breast boards is installed in the both sides at plantation position, the fixed mount material is a pottery, permanent building materials such as cement, design has N high outside and low outside skewed slot on the fixed mount, the width of skewed slot, thickness specification and breast boards coincide, breast boards can be placed wherein just, the gradient of skewed slot is parallel with the bottom gradient, horizontal breadth decision after the distance of skewed slot is installed by the slump of planting soil and breast boards, the vertical height of lastblock breast boards minimum point and next piece breast boards peak is 1: 1.5 with the ratio of this breast boards horizontal breadth among the present invention.(3) water-proofing treatment need be carried out flexible water to building substrate when planting and be handled on buildings such as exterior wall, inclined roof, viaduct, prevent to plant the destruction of water to building body, will carry out careful processing to the bottom discharge mouth during waterproof construction; And when on non-buildings such as hillside, riverbank, planting, then need not waterproof, but need to reinforce matrix, prevent the landslide or cave in.(4) stopping area is set, the purpose that stopping area is set is to destroy building body after stoping root system of plant to penetrate watertight composition, so select the rubber and plastic chemistry root resistance material corrosion-resistant, that the life-span is long, root resistance material overlap joint must be tightly seamless, and the lap of splice is no less than 100mm; (5) breast boards is installed, breast boards is a key of the present invention, and breast boards adopts permanent construction materials such as pottery, reinforcement concrete; The breast boards vertical section is a parallelogram, and after the fixed mount skewed slot was injected at the breast boards two ends, the outer facade of breast boards and main body formed a plane, and projection can not be arranged; When the plantation matrix is not a plane, when having projection, depression or other irregularly shaped, require breast boards two ends and skewed slot identical outside, the centre is also consistent with the matrix profile; The breast boards Lower Half is provided with N permeable aperture, and hole diameter is 2---10mm; For alleviating the load-bearing burden of breast boards, under every breast boards, settle N " Z " type support, support is installed on the bottom ramp by cement mortar, upwards hold up bottom breast boards, the breast boards lower edge just is stuck in the terraced Kan Chu of " Z " type support, the breast boards lower edge has 50 with the plantation matrix---and the space of 200mm, this space make planting soil link up into an integral body, are beneficial to root system of plant development and soil moisture conservation.(5) feed pipe is installed, at the planting area top and other position that needs drip irrigation or filtration irrigation device are installed.(6) filling planting soil must be laid the fine anticorrosion screen cloth of multiple stratification on the bottom discharge mouth before the filling planting soil, tamp rubble, coarse sand isotonic water layer again, stops up discharge outlet to prevent earth; Planting soil is selected lightweight nutrition soil for use, and fill method is for installing behind the several piece breast boards with the bamboo bar with the soil tamping or water it is sunk naturally, and then installation several piece breast boards, adds soil, tamping, the like this circulation.(7) sealing fixed mount, soil with the fixed mount wiped clean, is fixed to the fixed mount cover plate on the fixed mount after filling and finishing, and makes breast boards insert the skewed slot part by complete closed, prevents from because of storm wind root system of plant and breast boards to be pulled out together.(8) plant setting, wall slope plant is selected lawn, flowers and low brushwood for use, is main in order to avoid prune or prune plant less, and itself and soil keeping and demand for security are complementary.(9) later stage maintenance, the survival of plant, attractive in appearance all closely related with the later stage maintenance is regularly watered, fertilising, deinsectization and emergency maintenance cooperate and just can get a desired effect.
