Embodiment

[0018] Embodiment: certain weathered rock slope ecological slope greening method is as follows,

[0019] ① For a weathered rock slope with a height of 6 meters, a slope ratio of 1:1, and a length of 30 meters, carry out surface ecological greening;

[0020] ② Prepare 150m 3 Local loam, prepare 1.6m 3 Sodium aluminate, 3.2m 3 Polyacrylamide, 1.6m 3 Polyacrylic resin, 4.8m 3 Four kinds of powders of sodium silicate were mixed and stirred evenly, and then mixed with 150m 3 Stir the local loam, configure it as improved loose soil, and mix 7.5kg of ryegrass, tall fescue, bermudagrass, magnolia multiflora, torch fruit, black locust and the prepared improved loose soil evenly for later use;

[0021] ③Excavate the side slope, brush the slope, set out the line, tidy up the slope surface, set up drainage ditches at the top and the foot of the slope, and dig holes on the surface of the slope with a depth of 5cm and a spacing of 15cm;

[0022] ④Wedge the vertical slope of bamboo pil...

Abstract

The invention relates to a novel ecological side slope greening protective technology for solving the issue of ecological greening of a soil side slope and a rock side slope. The technology is characterized in that bamboo stakes and bamboo chips are used to protect the surface layer of the side slope; in addition, a modified soil is used to carry out culture greening; the modified soil consists of local soil and modifying agent; the modifying agent comprises sodium aluminate, polyacrylamide, polyacrylic resin and sodium silicate which are matched with soil according to the mass ratio of 1:2:1;3:93; the bamboo stakes are made of grown bamboos the ends of which enter the earth are cut sharp; the bamboo chips are made of bamboos with a diameter of 6-8 cm; the bamboos are cut open from the middle and made into bamboo chips with a length of 200-250cm; grass seeds are selected from ryegrass, festuca arundinacea and bushes are selected from indigofers amblyatha craib, fortune firethorn fruit and robinia pseudoacacia.

Description

technical field [0001] The invention relates to a side slope greening protection method, which belongs to the field of civil engineering design and construction. Background technique [0002] With the large-scale investment in national infrastructure, a large number of expressway projects and provincial highway projects have been started in my country. The route selection of the highway crosses the green belt, forming a large number of exposed slopes, and the vegetation is destroyed or even degraded. The slope protection design scheme of highway engineering often adopts cement concrete structure. Although the purpose of engineering protection is achieved, the performance in ecological protection is not good, especially for rocky slopes, and ecological protection is a big problem. The purpose of the present invention is based on the consideration of environmental protection and greening, adopts non-polluting and ecological protection technology, carries out greening protectio...
