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

[0017] Step 1, measuring and laying out

[0018] According to the construction drawing, the excavation boundary line is laid out, two end wedges are taken every 10 meters, a measuring rope is fixed and straightened in the middle, and lime is chipped along the edge of the measuring rope and is scattered while knocking;

[0019] Step 2, earthwork excavation

[0020] The earthwork excavation is carried out in a coordinated manner of earthwork machinery; the earthwork excavation is carried out in a segmented and zoned manner as a whole.

[0021] The earthwork excavation sequence and method must be consistent with the design requirements and comply with the principles of “slotting first, supporting first, excavating later, layering excavation, and strictly prohibiting over-excavation”; the excavation sequence is in accordance with the segmented and zoned excavation of the earthwork excavation construction drawing.

[0022] The earthwork excavation depth is 2-5 meters, and the excavation is carried out in 2-3 layers.

[0023] When multiple excavators are adopted to organize construction in multiple working faces, the width of each working face should be greater than 20m;

[0024] During the excavation process, the measurement personnel use RTK to measure the excavation depth at any time to avoid over-excavation, and after the excavation reaches the specified depth, 100-150mm of artificial finishing is reserved;

[0025] Step 3, acceptance

[0026] After the artificial finishing is completed, self-inspection is carried out, and after the self-inspection is qualified, the construction unit reports the supervision unit to organize relevant acceptance work;

[0027] Step 4, installation of snowflake vegetation protection slope network

[0028] When the first block is installed, the column is aligned with the ground along the flat land surface, the top of the vegetation protection slope network is hit by using a wooden hammer and a rubber hammer, and the vegetation protection slope network penetrates into the soil body due to the inertia of the hammering;

[0029] By adjusting the adjusting screw on the inner column, the anchor rod body is moved upwards by a small distance, and the end of the anchor rod body away from the nut is moved above the bottom of the stop piece. The adjusting screw is adjusted in the opposite direction to move the anchor rod body downwards. In the process of moving the anchor rod body downwards, the stop piece is expanded, so that the anchor rod body is anchored in the soil layer through the axial slot;

[0030] The remaining snowflake branch pipes are installed on the outer side of the first block, the corresponding connecting blocks one are connected by using the connecting block two, and finally the snowflake vegetation protection slope network is formed;

[0031] Step 5, soil attachment

[0032] After the slope protection network is formed, the surface is covered with a layer of planting soil, and water is sprayed for maintenance. During the maintenance period, the water in the soil slowly flows into the column through the water collecting hole. The water is guided upwards by capillary action through the water absorbing cotton, and the water is sent to the seed pipe in the snowflake branch pipe through the water absorbing cotton strip. The grass seeds are nourished by the nutrient soil, and grow downwards and upwards to form a vegetation protection slope.

[0033] When the seed pipe is short of water, heat will accumulate inside. The heat is transmitted to the memory metal wire through the heat conducting metal wire. The memory metal wire expands and drives the piston to move upwards in the vertical branch pipe. Through the meshing of the transmission rack and the gear, the rotating cylinder is rotated. The rotating cylinder can only rotate the extrusion piece in one direction under the action of the ratchet and tooth structure. The rotating direction is towards the seed pipe. At the same time, the water absorbing cotton strip is extruded towards the seed pipe to prevent the water in the seed pipe from being seriously depleted.

[0034] Compared with the prior art, the present application has the following advantages:

[0035] 1. By increasing the water absorption cotton stick in the column and the water absorption cotton stick in the snowflake branch pipe, the water absorption cotton stick and the water absorption cotton stick are connected to guide the moisture capillary to the seed pipe, which is used for maintenance and long-term support of vegetation.

[0036] 2. The active water feeding assembly is additionally arranged between the seed pipe and the snowflake branch pipe, when the temperature accumulation of the seed pipe affects the growth conditions of the 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 water absorption cotton stick is fed to the side of the seed pipe, and the vegetation or grass seed in the seed pipe is supplied to grow, so that the premature death is avoided.

[0037] 3. The column is arranged as an inner column and an outer column, the inner column is used to realize the outward movement of the anchor rod body and then is anchored in the soil layer, the stability of the snowflake slope protection is improved, the connecting block one of the adjacent two snowflake slope protection structures is connected and fixed through the connecting block two, and then the formation of the snowflake slope protection network and the stability and reliability of the network structure are realized.

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

[0061] Step 1, measuring and laying out

[0062] According to the construction drawing, lay out the excavation boundary line, take two end wedges every 10 meters, use a measuring rope to fix and straighten in the middle, and use a shovel to shovel lime along the edge of the measuring rope and knock and sprinkle the lime line;

[0063] Step 2, earthwork excavation

[0064] The earthwork excavation is carried out in a coordinated manner of earthwork machinery; the earthwork excavation is carried out in sections and zones;

[0065] The earthwork excavation sequence and method must be consistent with the design requirements and comply with the principles of "supporting before trenching, digging after supporting, layer-by-layer excavation, and strictly prohibiting over-excavation"; the excavation sequence is carried out in sections and zones according to the earthwork excavation construction drawing;

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

[0067] When multiple excavators and multiple working faces are used to organize construction in different regions, the width of each working face should be greater than 20m;

[0068] During the excavation process, the measurement personnel use RTK to measure the excavation depth at any time to avoid over-excavation, and after excavating to the specified depth, 100-150mm of artificial finishing is reserved;

[0069] Step 3, acceptance

[0070] After the artificial finishing is completed, self-inspection is carried out, and after the self-inspection is qualified, the construction unit reports to the supervision unit to organize relevant acceptance work;

[0071] Step 4, install the snowflakes vegetation protection slope network

[0072] When installing the first block, align the column 10 with the ground along the flat land surface, and use a wooden hammer or rubber hammer to hit the top of the vegetation protection slope network, so that the vegetation protection slope network penetrates into the soil body due to the inertia of the hammering;

[0073] By adjusting the adjusting screw 104 on the inner column 101, the anchor rod body 105 is moved a small distance upwards, and the end of the anchor rod body 105 away from the nut 103 is moved above the bottom of the stop plate 107.

The grass seeds are nourished by the nutrient soil, and grow downward and upward to form a vegetation protection slope;

[0077] When the seed pipe 20 lacks water, heat will accumulate inside. The heat is transferred to the memory metal wire 22 through the heat conducting metal wire 21.
