[0087] The embodiment further provides a large steel reinforcement cage installation method based on the large steel reinforcement cage installation device.

[0088] Step S1: a plurality of screw clamps 30 are spaced apart in the vertical direction and arranged on the truss 3 in advance;

[0089] Step S2: the truss 3 is arranged vertically around the pile hole 1, and a docking mechanism 4 is hoisted on the top of the truss 3, the docking mechanism 4 comprising a sliding seat 41, a hoisting rope 42 and a vertical driving member 43;

[0090] Step S3: two adjacent segment steel reinforcement cages 2 are hoisted in sequence, the two segment steel reinforcement cages 2 are controlled to pass through the docking mechanism 4 and the truss 3, and are temporarily fixed on the truss 3 by corresponding screw clamp groups; each vertical driving member is controlled to drive the corresponding hoisting rope 42 below, connect each hoisting rope 42 and the segment steel reinforcement cage 2 above, and release the connection between the segment steel reinforcement cage 2 above and the corresponding screw clamp group;

[0091] Step S4: each sliding seat 41 is driven to adjust its horizontal and vertical positions according to the position of the segment steel reinforcement cage 2 above in the horizontal plane, until the segment steel reinforcement cage 2 above is aligned with the segment steel reinforcement cage 2 below;

[0092] Step S5: the segment steel reinforcement cage 2 above is connected with the segment steel reinforcement cage 2 below, and the connection between the segment steel reinforcement cage 2 below and the corresponding screw clamp group is released;

[0093] Step S6: synchronously control all vertical driving members 43 to drive two segmental reinforcement cages 2 through respective hoisting ropes 42 to be lowered into the pile hole 1.

[0094] In the step S3, the two segmental reinforcement cages 2 are hoisted in sequence; the two segmental reinforcement cages 2 pass through the butt joint mechanism 4 and the truss 3, and are temporarily fixed on the truss 3 by the corresponding screw clamps. The specific method includes:

[0095] Hoist the first segmental reinforcement cage, and control the segmental reinforcement cage 2 to pass through the butt joint mechanism 4 and the truss 3 in sequence;

[0096] Fix the first segmental reinforcement cage segmental reinforcement cage 2 on the truss 3 by the corresponding screw clamps on the truss 3;

[0097] Hoist the second segmental reinforcement cage, and control the segmental reinforcement cage 2 to pass through the butt joint mechanism 4 and the truss 3 in sequence and be located above the first segmental reinforcement cage;

[0098] Fix the second segmental reinforcement cage on the truss 3 by the corresponding screw clamps on the truss 3.

[0099] The tower crane is used to hoist the segmental reinforcement cage 2 into the installation device, the butt joint mechanism 4 in the installation device is used for alignment and lowering, the truss 3 and the screw clamps are used for temporary fixing of the segmental reinforcement cage 2, and the accurate installation of the large-size reinforcement cage can be ensured. The embodiment of the application can meet the installation requirements of the reinforcement cage with a diameter of 2.5-3.5 m and a weight of 50-100 t, and has high practicability and universality.

[0100] In addition, the embodiment of the application can solve the problem of installation of the large-size reinforcement cage by the large hoisting device (such as the tower crane), and can reliably install the reinforcement cage in a steep canyon area under the action of long-time canyon wind.

[0101] Preferably, in the process of hoisting the first segmental reinforcement cage and controlling the segmental reinforcement cage 2 to pass through the butt joint mechanism 4 and the truss 3 in sequence, the installation method further includes:

[0107] In the embodiment of the present application, the sliding seat 41 on the docking mechanism 4 can move anywhere above the lowering channel formed by the truss 3, therefore, if the segmental reinforcement cage 2 is intended to be lowered into the truss 3, the sliding rails 44 are arranged near the top of the truss 3 on both sides, and the two moving rods 45 are slid on the two sliding rails 44, so that the two moving rods 45 do not block the lowering of the segmental reinforcement cage 2.

[0108] Specifically, the segmental reinforcement cage 2 is hoisted by a tower crane. According to the lowering channel formed by the truss 3 and the pile hole 1, the segmental reinforcement cage 2 can be prevented from swinging greatly under the action of canyon wind during the lowering process, thereby reducing the construction efficiency.
