Description

Technical Field

[0001] This invention relates to the field of mine protection technology, and in particular to an ecological slope protection structure and its construction method. Background Technology

[0002] Limestone, as an important resource and building material, is a primary target in mining operations. Large-scale open-pit mining has resulted in numerous exposed limestone mining slopes. Limestone mining typically involves a large mining area, causing significant damage to the natural ecological environment. As the scale of mining increases, slope protection becomes essential, and traditional slope engineering methods are generally used for slope protection.

[0003] Existing ecological protection structures for mine slopes include a cleared slope, a steel rope net covering the slope, a ring net covering the steel rope net, and fixing components to secure the steel rope net and the ring net to the slope. During slope protection, debris and loose rocks are cleared from the mined slope, the steel rope net and the ring net are covered, and then the fixing components are used to anchor the steel rope net and the ring net to the slope. The existing technical solutions described above have the following drawbacks:

[0004] (1): Steel rope nets and ring nets are mesh-like protective structures. In the protection of limestone slopes, due to the risk of limestone fracturing and falling, the mesh-like protective structures are difficult to block sufficiently, resulting in a large amount of gravel still easily sliding out of the protective structure.

[0005] (2): The installation of steel rope nets and ring nets requires manual winding and threading of various nets, which is quite complicated and requires a lot of manpower and resources.

[0006] Therefore, this invention proposes an ecological slope protection structure and its construction method to solve the problems existing in the prior art. Summary of the Invention

[0007] To address the aforementioned problems, this invention proposes an ecological slope protection structure and its construction method. This ecological slope protection structure and its construction method utilize mud slurry to bond and stabilize the limestone slope surface, and each layer of stepped slabs plays a supporting role, effectively preventing various types of gravel from sliding down.

[0008] To achieve the objectives of this invention, the following technical solution is provided: a slope ecological protection structure, comprising a bottom baffle, side baffles, and stepped plates. Multiple sets of side baffles are provided. The bottom baffle is connected to the lower end between two adjacent sets of side baffles. Multiple sets of stepped plates are connected between two adjacent sets of side baffles and are equidistantly arranged. Both sides of each stepped plate are fixed to the side baffles on both sides via quick-connect assemblies. A shotcrete pipe with shotcrete holes is located below one end of each stepped plate. One end of the shotcrete pipe is connected to a guide pipe. A frame is provided above the area between two adjacent sets of stepped plates, and both sides of the frame are fixed to the side baffles on both sides via quick-connect assemblies.

[0009] The side baffles and step plates are fixed to the mine slope, and a filling space is formed between the side baffles, step plates and the upper frame, and the interior of the filling space is used to fill mud.

[0010] A further improvement is that the quick-connect assembly includes quick-connect rods and quick-connect slots, and the quick-connect slots are provided on both sides of the side baffle, and multiple sets of quick-connect slots are provided at equal intervals. The quick-connect rods are provided on both sides of the step plate and both sides of the frame, and the quick-connect rods are adapted to the quick-connect slots.

[0011] A further improvement is that the quick-connect rod is a T-shaped rod, the quick-connect slot is a T-shaped slot, and a pressure plate is provided at the top of the quick-connect rod, with the bottom area of ​​the pressure plate being larger than the insertion area of ​​the quick-connect slot.

[0012] A further improvement is that an anchor rod is inserted into the clamping plate, and the anchor rod passes through the quick-connect rod, with the lower end of the anchor rod inserted into the mine slope.

[0013] A further improvement is that the frame is provided with planting frames inside, and multiple sets of planting frames are provided. The planting frames are used for planting plants after the mud inside the filling space has been shaped.

[0014] A further improvement is that: both sides of one end of the planting frame are provided with clearance grooves, the conduit extends out of the planting space through the clearance grooves, and the conduit is used to connect to the mud pump to introduce mud into the spray pipe.

[0015] A further improvement is that hooks are provided at the lower ends of both sides of the bottom baffle, and springs are provided on both sides of the bottom baffle, with the bottom baffle connected to the hooks via the springs.

[0016] A construction method for an ecological slope protection structure includes the following steps:

[0017] Step 1: Select a suitable location on the mine slope and plan the spacing between adjacent side panels;

[0018] Step 2: Place the side baffle in the selected position and anchor it into the interior of the mine slope from both ends to achieve pre-positioning;

[0019] Step 3: Install the step plate between two adjacent sets of side baffles, insert the quick-connect rods on both sides of the step plate into the quick slot, so that the clamping plate presses against the quick slot;

[0020] Step 4: Drive anchor bolts into the clamping plate and drive the anchor bolts into the mine slope to fix the step plate;

[0021] Step 5: Install the frame between two adjacent sets of step plates, insert the quick-connect rods on both sides of the frame into the quick-connect slots, drive the anchor rods into the mine slope, and fix the frame.

[0022] Step 6: Pull the guide pipe out of the clearance groove, connect the guide pipe to the mud pump, and input mud into the spray pipe. The mud will be sprayed out from the spray hole and fill the filling space.

[0023] Step 7: Remove the mud pump and wait for the mud in the filling space to solidify before sowing plant seeds into the mud through the planting frame.
