Problems solved by technology

[0005] 1. Because limestone will gradually dissolve and collapse under the action of long-term water, and the slag itself has certain pores when it is accumulated, and nutrients are easy to lose, so it is difficult to maintain the long-term stability of the limestone waste slag yard;
[0006] 2. Since the soil environment of the limestone waste dump is alkaline, it is difficult to ensure the stable growth of plants

Embodiment 1

[0040] An ecological protection system of limestone slag, such as figure 1As shown, it includes a slag layer 1 , a water guide cloth 2 and a functional layer 3 arranged in sequence from bottom to top, and several anchor rods 4 for fixing the water guide cloth 2 and the functional layer 3 on the slag layer 1 . Wherein, the anchor rod 4 adopts threaded steel with a diameter of 12 cm and a length of 35 cm.

[0041] The gravel layer 1 includes a bottom layer 5, and a transition layer 6 above the bottom layer 5 and poured with a stabilizer. Wherein, the thickness of the transition layer 6 is 100 cm, and the thickness of the bottom layer 5 is 80 cm. The stabilizer comprises 10 parts of bacillus pasteurian culture liquid filtrate, 2 parts of urea aqueous solution with a mass concentration of 10%, and 3 parts of ferrous sulfate aqueous solution with a mass concentration of 10%, in parts by weight.

Abstract

The invention relates to the technical field of stone slag protection, and discloses an ecological protection system for a waste limestone slag yard. The ecological protection system comprises a stoneslag layer, water guide cloth and a functional layer which are sequentially arranged from bottom to top, and further comprises a plurality of anchor rods for fixing the water guide cloth and the functional layer on the stone slag layer, wherein the stone slag layer comprises a bottom layer and a transition layer which is positioned above the bottom layer and is poured with a stabilizer; and the functional layer comprises a substrate layer and functional nets arranged on the upper side and the lower side of the substrate layer respectively. According to the characteristics of the waste limestone slag yard, a functional microorganism-plant synergistic protection system is established, synergistic stability of the waste limestone slag yard is achieved, ecological protection effect on the waste limestone slag yard is improved, and the problems of water erosion collapse of a limestone area and stable growth of plants under an alkaline condition of a traditional ecological protection structure are solved.

Description

technical field [0001] The invention relates to the technical field of ecological protection of waste slag yards, in particular to an ecological protection system for limestone waste slag yards. Background technique [0002] Karst landforms are not only widely distributed in the world, but also occupy an important position in China. Karst landform is a landform type with a relatively wide distribution area in China, especially in the southwest region of China, where the development of karst landform is particularly typical. Limestone is the main rock for the development of karst landforms, and its mineral composition is mainly calcite, accompanied by dolomite, magnesite and other carbonate minerals. [0003] Most of the long-distance natural gas pipeline projects require the excavation and backfilling of pipe trenches, which resulted in the emergence of a large number of limestone slag dumps in the southwest karst area. Because limestone is easily eroded under favorable co...
