[0028] As shown in Figure 5 A river regulation ecological revetment, comprising a gabion revetment 3 laid on the surface of a slope body, and a gabion foundation 1 connected to the lower end of the gabion revetment 3, the gabion foundation 1 being embedded at the junction of the slope body and the riverbed, characterized in that the gabion foundation 1 is connected with a gabion foot 2 laid on the riverbed, and a plurality of reinforced anchor rods 4 are arranged between the gabion revetment 3 and the riverbed.

[0029] A construction method of a river regulation ecological revetment, comprising the following steps:

[0030] A. Excavating a pre-embedded pit at the junction of the slope body and the riverbed and on both sides of the riverbed, and backfilling the pre-embedded pit with the gabion foundation 1;

[0031] B. Laying the gabion revetment 3 on the surface of the slope body and the gabion foot 2 on the riverbed, and binding and connecting the gabion revetment 3 and the gabion foot 2 with the gabion foundation 1 respectively;

[0032] C. Inserting a plurality of reinforced anchor rods 4 through the gabion revetment 3 and into the slope body, and during the insertion, first rotating the rotating rod 512 counterclockwise to make the insertion rod 62 completely inside the anchor rod body 41, then rotating the advancing disc 42 to make the drill bit 511 and the anchor rod body 41 extend into the soil of the slope body, then loosening the rotating rod 512, and the insertion rod 62 extends into the soil through the vertical slot 411 to limit the anchor rod body 41, and then filling stones into the gabion revetment 3 to complete the installation of the reinforced anchor rod 4;

[0033] D. When the moisture of the soil around the drill bit 511 increases, the supporting effect of the soil decreases, at this time the drill bit 511 rotates under the elastic force of the torsional spring 514 and continues to drill into the deeper soil, and during the downward rotation of the drill bit 511, the insertion rod 62 synchronously shrinks into the anchor rod body 41, and under the pulling action of the connecting spring 81, the insertion rod 62 moves downward with the drill bit 511, and when the drill bit 511 stops drilling, the insertion rod 62 synchronously expands into the soil under the elastic force of the reset spring 65, thereby ensuring that the supporting strength of the anchor rod body 41 to the gabion revetment 3 does not change.

[0034] The length of the gabion protection foot 2 is greater than twice the maximum scouring depth of the riverbed, and when the maximum scouring depth is reached, the scouring depth of the riverbed has an approximate 1:2.0 slope with the horizontal direction to reach a stable state.

[0035] When the rotating rod 512 is rotated counterclockwise, the ratchet wheel 71 can be driven to rotate counterclockwise through the engagement of the pawl 73 and the ratchet wheel 71, and then the rotating disc 64 is rotated, and when the rotating disc 64 is rotated, the T-shaped buckle 63 is driven to move along the arc-shaped slot 641 to the center of the rotating disc 64 against the damping force of the return spring 65, so that the insertion rod 62 is retracted into the anchor rod body 41, and the drilling of the drill bit 511 is not hindered.

[0036] During the drilling process of the anchor rod body 41 with the drill bit 511, the torsion spring 514 is always in a compressed state and is inclined.

[0037] When the moisture content of the soil around the drill bit 511 increases, the damping of the soil on the drill bit 511 is less than the elastic force of the torsion spring 514, at this time, the torsion spring 514 will push the drill bit 511 to rotate and move downward during the resetting process, so that the drill bit 511 automatically drills, and when the drill bit 511 drills into the soil with lower moisture content, the resistance of the soil to the drill bit 511 is equal to the elastic force of the torsion spring 514, and the drill bit 511 stops drilling. Thus, the drill bit 511 is in a deeper layer of soil, and the supporting strength of the gabion protection slope 3 does not change, preventing the gabion protection slope 3 from moving and failing.

[0038] When the drill bit 511 just starts to rotate downward, the rotating rod 512 just starts to rotate, and the insertion rod 62 has not been completely retracted into the anchor rod body 41, so the entire second reinforcing assembly does not immediately move downward, when the insertion rod 62 is completely retracted into the anchor rod body 41, the insertion rod 62 is released from the limit, and under the pulling action of the connecting spring 81, the sliding rod 522 drives multiple insertion rods 62 to move downward, when the drill bit 511 stops rotating, the rotating rod 512 remains stationary, and under the elastic force of the return spring 65, the rotating disc 64 rotates clockwise, driving the T-shaped buckle 63 to move along the arc-shaped slot 641 to the edge of the rotating disc 64, the insertion rod 62 expands outward and inserts into the soil through the vertical slot 411. Thus, the multiple insertion rods 62 are limited in a direction perpendicular to the drill bit 511, preventing the anchor rod body 41 from moving in the drilling direction, ensuring the supporting stability of the anchor rod body 41 and preventing the gabion protection slope 3 from moving.

[0039] The gabion protection slope 3 will generate a certain shear force on the anchor rod body 41, and the extrusion between the multiple insertion rods 62 and the soil can share part of the shear force of the anchor rod body 41, thereby avoiding deformation of the anchor rod body 41 and further enhancing the supporting strength of the anchor rod body 41.

[0040] When filling the gabion revetment 3 with stones, the pressing disc 91 is tightly attached to the upper surface of the gabion, and the pressing disc 91 can keep the stones filled in the gabion revetment 3 in close contact by the pressure spring 92, preventing the stones from moving.
