[0016] A construction method for a snowflake vegetation slope protection network, comprising steaming:

[0017] Step 1: Measure and lay out

[0018] Lay out the excavation line according to the construction drawings, nail wooden wedges at both ends every 10 meters, use a measuring rope to fix and straighten the middle, use a shovel to shovel lime along the edge of the measuring rope and spread the lime line while knocking;

[0019] Step 2: Earth excavation

[0020] The method of coordinated operation of earth-moving machinery; the overall earthwork excavation is carried out in sections and zones;

[0021] The excavation sequence and method must be consistent with the design requirements and follow the principle of "supporting before trenching, excavating in layers, and strictly prohibiting over-excavation". The excavation sequence should be carried out in sections and zones according to the construction drawings of the excavation operation.

[0027] Step 4: Install the snowflake vegetation slope protection network

[0028] When installing the first piece, level the ground surface, align the column with the ground, and use a wooden hammer or rubber hammer to hit the top of the vegetation slope protection net. The vegetation slope protection net will penetrate into the soil due to the inertia of the hammer.

[0029] The bolt body is moved upward a short distance by adjusting the adjusting screw on the inner column until the end of the bolt body away from the nut moves above the bottom of the baffle. The bolt body is moved downward by adjusting the adjusting screw in the opposite direction. During the downward movement of the bolt body, the baffle is extended outward, causing the bolt body to pass through the axial groove and be anchored in the soil layer.

[0030] Install the remaining snowflake branches on the outside of the first block, and use the connection block 2 to connect and adapt the corresponding connection block 1, and finally form a snowflake vegetation slope protection network;

[0031] Step 5: Attach soil

[0032] After the slope protection net is formed, a layer of planting soil is covered on the surface and watered for maintenance. During the maintenance period, the water in the soil slowly flows into the column through the water collection holes, and the water is drained upward through the absorbent cotton. The water is sent to the seed tube on the snowflake branch pipe through the absorbent cotton strip. The grass seeds take root downward and grow upward under the nourishment of the nutrient soil to form a vegetation slope protection;

[0033] When there is a lack of water in the seed tube, heat will accumulate inside. The heat is transferred to the memory wire through the heat conduction wire. The memory wire expands due to the heat and drives the piston upward in the vertical branch pipe. The transmission rack and the gear mesh together to drive the rotating cylinder to rotate. Under the action of the ratchet structure, the rotating cylinder can only rotate the extrusion part in one direction, and the rotation direction is toward the seed tube. At the same time, the absorbent cotton strip is squeezed to transport water into the seed tube to prevent serious water loss in the seed tube.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. By adding absorbent cotton swabs in the column and absorbent cotton strips in the snowflake branch tube, the absorbent cotton strips and the absorbent cotton swabs are connected to drain water into the seed tube through capillary drainage, which is used for maintenance and long-term support of vegetation.

[0036] 2. An active water supply component is added between the seed tube and the snowflake branch pipe. When the temperature accumulation of the seed tube affects the growth conditions of vegetation, the reciprocating motion of the piston is realized through the memory alloy wire, and then the rotating cylinder is driven to rotate through the transmission rack and gear, so that the absorbent cotton strip is sent to one side of the seed tube to supply water to the growth of vegetation or grass seeds in the seed tube to avoid premature death.

[0037] 3. Set the column as inner and outer columns, use the inner column to realize the outward movement of the anchor rod body and then anchor it in the soil layer, improve the stability of the snowflake slope protection, use the connecting block 2 to connect and fix the connecting block 1 of the two adjacent snowflake slope protection structures, thereby realizing the formation of the snowflake slope protection network and the stability and reliability of the network structure.

[0060] A construction method for a snowflake vegetation slope protection network, comprising steaming:

[0061] Step 1: Measure and lay out

[0062] Lay out the excavation line according to the construction drawings, nail wooden wedges at both ends every 10 meters, use a measuring rope to fix and straighten the middle, use a shovel to shovel lime along the edge of the measuring rope and spread the lime line while knocking;

[0063] Step 2: Earth excavation

[0064] The method of coordinated operation of earth-moving machinery; the overall earthwork excavation is carried out in sections and zones;

[0065] The excavation sequence and method must be consistent with the design requirements and follow the principle of "supporting before trenching, excavating in layers, and strictly prohibiting over-excavation". The excavation sequence should be carried out in sections and zones according to the construction drawings of the excavation operation.

[0066] The excavation depth is 2-5 meters, and the excavation is carried out layer by layer in 2-3 layers.

[0067] When multiple excavators and multiple working surfaces are used for construction in different areas, the width of each working surface should be greater than 20m;

[0068] During the excavation process, surveyors use RTK to measure the excavation depth at any time to avoid over-excavation. After excavation to the specified depth, 100-150mm is reserved for manual trimming;

[0069] Step 3, Acceptance

[0070] After the manual repair is completed, self-inspection will be carried out. If the self-inspection is qualified, the construction unit will report it to the supervision unit to organize relevant acceptance work;

[0071] Step 4: Install the snowflake vegetation slope protection network

[0072] When installing the first piece, level the ground surface, align the column 10 with the ground, and use a wooden hammer or a rubber hammer to hit the top of the vegetation slope protection net. The vegetation slope protection net penetrates downward into the soil due to the inertia of the hammer.

[0073] The adjusting screw 104 on the inner column 101 is adjusted to move the anchor rod 105 upward for a short distance until the end of the anchor rod 105 away from the nut 103 is moved above the bottom of the baffle 107, and the adjusting screw 104 is adjusted in the reverse direction to move the anchor rod 105 downward.

During the maintenance period, the water in the soil slowly flows into the column 10 through the water collection hole 16, and the water is drained upward by the water-absorbing cotton. The water is sent to the seed tube 20 on the snowflake branch pipe 11 through the water-absorbing cotton strip 14. The grass seeds take root downward and grow upward under the nourishment of the nutrient soil to form a vegetation slope protection;

[0077] When there is a lack of water in the seed tube 20, heat will accumulate inside. The heat is transferred to the memory wire 22 through the heat conduction wire 21. The memory wire 22 expands due to the heat and drives the piston 24 to move upward in the vertical branch pipe 23.

Under the action of the ratchet structure, the rotating cylinder 26 can only rotate the extrusion piece 28 in one direction, and the rotation direction is toward the seed tube 20. At the same time, the absorbent cotton strip 14 is squeezed to transport water into the seed tube 20 to prevent serious loss of water in the seed tube 20.
