Description

Technical Field

[0001] The present invention relates to the field of ecological restoration engineering for rocky slopes such as mines and highways, and particularly relates to a rock - soil - plant - microorganism slope ecological restoration system and a construction method thereof. Background Art

[0002] The development of social economy is inseparable from various development and construction projects. While promoting the rapid development of regional economy, development and construction projects also cause damage to the natural ecological environment in the construction area and its surrounding areas. High - fill and deep - cut in engineering construction such as railways, highways, water conservancy, and mines directly damage the ground surface, generating a large area of exposed high and steep slopes, leading to the deterioration of the ecological environment around the project area. Especially the newly increased large - area exposed slopes cause landscape disharmony and soil erosion, and even trigger secondary geological disasters such as landslides and collapses; mainly manifested as changing the topography and geomorphology, disturbing the soil structure, destroying the plant community, reducing biodiversity, affecting the regional climate, causing and intensifying soil erosion, etc. Therefore, the ecological restoration and reconstruction of exposed slopes (also known as slope greening) is extremely urgent.

[0003] At present, the slope greening treatment technologies for some special slopes at home and abroad are still relatively weak. For example, for high and steep rocky slopes dozens of meters or even hundreds of meters high, mainly slope cutting, setting up steps, spraying and sowing with net hanging and other greening technologies are used for treatment. There are still the following problems in using these technologies for greening: (1) Since the geocell serves as the root soil skeleton of the greening plants and has a large bearing capacity, it is easy to slide on large - area high and steep rocky slopes, and it is relatively difficult to install and fix; (2) Although traditional technologies also set up multi - level slope - cutting platforms, the platforms lack effective longitudinal drainage ditches for timely water diversion and collection, which is likely to cause two problems: ① Rainwater flushes the backfilled planting soil layer in the geocell, resulting in the washing away of a large amount of nutrient soil for plant growth; ② A large amount of collected water is contained in the geocell planting soil layer, increasing the load weight of the geocell, and seriously tearing the geocell when severe. (3) The installation efficiency at the splicing joints of each geocell is low, and the connection is not firm; (4) Only using plants to conduct ecological restoration on the exposed slope, the plant survival rate is low, the growth rate is slow, the greening efficiency is low, and it is difficult to restore the original plant community structure and ecosystem function.

[0004] Therefore, how to improve the installation efficiency and fixity of geocells on large - area high and steep rocky slopes, reduce the washing of nutrient soil in the geocell by rainwater, reduce the load weight of the geocell, use new ecological restoration technologies to conduct ecological restoration on the exposed slope, improve the plant survival rate and growth rate, and quickly restore the original plant community structure and ecosystem function is the main problem to be solved currently.

[0038] As Figures 1 - 10 described above, the present invention provides a rock mass - soil - plant - microorganism slope ecological restoration system and construction method, including the following steps:

[0039] Step 1. Slope cleaning: Familiarize with the requirements of the design drawings and relevant documents, prepare the construction plan for the rock mass - soil - plant - microorganism slope ecological restoration system and the special safety plan for high - altitude operations. Clean the loose stones on the rock slope 1, and on - site measure and set out the driving positions of each anchor rod 4, the excavation line of the slope - cutting bench 16, the excavation line of the bottom pit 19 of the slope, and the construction red line of the toe - slide wall 21. Determine the number of blocks of the geocell 13 and the dimensions of each block according to the size and slope of the rock slope 1.

[0040] Step 2. Excavate the bench and the pit: Use an excavator to carry out graded excavation of the slope - cutting bench 16 from the top of the slope to the bottom according to the excavation line of the slope - cutting bench 16. Excavate the longitudinal drainage ditch 18 on each slope - cutting bench 16, and lay a layer of permeable geotextile 17 on the top of the longitudinal drainage ditch 18 on the bench.

[0041] Step 3. Construction of the toe - slide wall and the drainage ditch: Excavate the bottom pit 19 of the slope according to the excavation line of the bottom pit 19 of the slope. Excavate three longitudinal drainage ditches 25 at the bottom of the bottom pit 19 of the slope, and excavate transverse drainage ditches 20 at uniform intervals at the bottom. The longitudinal drainage ditches 25 at the bottom and the transverse drainage ditches 20 at the bottom intersect with each other, and lay a layer of permeable geotextile 17 on the upper part of the longitudinal and transverse drainage ditches at the bottom. Build the toe - slide wall 21 according to the construction red line of the toe - slide wall 21, install a PVC pipe 22 inside the toe - slide wall 21, connect the PVC pipe 22 with the transverse drainage ditch 20 at the bottom, and pour a drainage ditch 23 outside the toe - slide wall 21 to overlap with the natural ground 24.

[0042] Step 4: Install anchor bolts: Drill anchor bolt holes 2 according to the positioning line of the anchor bolts 4, install the anchor bolts 4, and inject cement slurry 3 for anchoring. After the slope top is trimmed, set up the slope top anchor bolt guardrail 5. Lay a steel mesh 6 on the rock slope 1. The steel mesh 6 is laid in three layers. The top of the steel mesh 6 is wound around the slope top anchor bolt guardrail 5. Each anchor bolt 4 passes through the grid of the steel mesh 6. Install steel backing plates 9 on the anchor bolts 4 to press the steel mesh 6 tightly to prevent it from rebounding and bulging.

[0043] Step 5: Pour ecological concrete: Pour the ecological concrete layer 7 from the bottom of the slope to the top of the slope. The ecological concrete layer 7 completely covers the steel mesh 6. The ecological concrete layer 7 is poured in sections and subsections, and the pouring thickness on the rock slope 1, the trimmed slope bench 16, and the bottom pit 19 is the same.

[0044] Step 6: Install tie bars: Install anchor fittings 10 on the anchor bolts 4, fix multiple tie bars 11 on the anchor fittings 10. The multiple tie bars 11 are evenly and dispersedly arranged, and a threaded enlarged head 28 is provided at the end of each tie bar 11.

After the tie bars 11 pass through the cells of the geocells 13, put a cross-shaped clamping bar 12 on the threaded enlarged head 28 at the end of the tie bar 11, and install a nut 26 and a gasket 27. After the cross-shaped clamping bar 12 is clamped on the cells of the geocells 13, adjust the tightness of the nut 26 to make the cross-shaped clamping bar 12 press the geocells 13 tightly, so as to realize the function of fixing the geocells 13 by the anchor bolt - tie bar - cross-shaped clamping bar structure. U-shaped steel nails 14 are installed between adjacent geocell blocks, such as between block A1 and block B1, and between block A1 and block A2, for connection. At the same time, vertical bench nails 15 are driven at the trimmed slope bench 16 for enhanced locking. Both the U-shaped steel nails 14 and the bench nails 15 need to be driven into the rock slope 1 to a certain depth.

[0046] Step 8: Prepare the nutrient soil layer: Prepare nutrient soil by mixing local fertile soil, microbial organic fertilizer, compound fertilizer, water retention agent, soil conditioner and other materials in a certain proportion. After the nutrient soil is evenly stirred, it needs to pass through a 1 cm sieve to keep the prepared nutrient soil layer delicate and uniform.

[0047] Step 9: Screen plants and microorganisms: Cultivate different kinds of microbial strains in the laboratory in combination with the local climate conditions, and select the strains with high activity and strong vitality through relevant tests; at the same time, mix plant seeds according to the local meteorological conditions and the surrounding environment, and select plant seeds that can promote the growth of each other with the microorganisms.

[0048] Step Ten: Spraying the nutrient soil layer: The prepared nutrient soil layer is evenly sprayed from the top of the slope to the bottom of the slope by a spraying machine to fill the geocell 13. The thickness of the sprayed nutrient soil layer must be uniform, which is 15 cm - 20 cm.

[0049] Step Eleven: Spraying the soil-plant-microorganism integrated matrix: The selected plant seeds, microorganisms, and nutrients are evenly mixed into an integrated matrix, and the soil-plant-microorganism integrated matrix is sprayed onto the surface layer of the geocell 13 to cover the nutrient soil layer, and a metal mesh is laid on the soil-plant-microorganism integrated matrix.

[0050] Step Twelve: Spraying water for maintenance: A sprayer is used to spray and maintain the soil-plant-microorganism integrated matrix on the geocell 13. After the seeds germinate, water is used for maintenance. Under the interaction of plants and microorganisms, rapid revegetation of the slope is achieved.
