The casing is hoisted by lifting equipment and vibrating hammers are used to apply vibration force to the steel casing to make it sink. After a period of vibration sinking, the sinking operation needs to be stopped and soil excavation operation is carried out. After the soil excavation is completed, the vibrating sinking operation is carried out again. This method leads to low construction efficiency and inability to synchronize the sinking and soil excavation operations.

[0019] The present invention proposes a construction method for a vibration force transmission structure for large-diameter steel casing construction. In step 1, during the sinking operation of the steel casing, the hook of the lifting equipment is connected to the hanging ear on the top of the arc-shaped protective cover to drive the device to lift, and then the gripper is used to clamp the steel casing. During the sinking, the vibration sinking device works to control the vibration drive motor to work, driving the power drive shaft to rotate, thereby controlling the rotation of the first pulley at one end, and the first belt connected to the surface transmission cooperates to drive the corresponding rotating shaft at the bottom to rotate. The rotation of the rotating shaft controls the top vibration cam and the top driving gear on the surface to work, and the two top driving gears mesh and work to synchronously control the synchronous rotation of the two rotating shafts at the top, driving the top vibration cam on the surface to rotate and generate vibration force. At the same time, the second pulley rotates and cooperates with the second belt to control the rotation of another corresponding rotating shaft at the bottom, thereby controlling the rotation of the bottom vibration cam at the bottom to generate vibration force, and the vibration force at the top and the vibration force at the bottom are combined to cooperate with the vibration steel casing sinking operation.

[0020] Step 2. When the vibration amplitude needs to be adjusted according to the sinking state, the vibration drive motor stops working, and its multiple rotating shafts stop rotating. Because a one-way bearing is installed inside the adjusting gear, while the rotating shaft rotates to generate vibration force, one end of the rotating shaft idles with the adjusting gear through the one-way bearing. When the adjusting gear is stationary, the rotating shaft rotates. When adjusting the amplitude, the adjusting motor drives the adjusting shaft to rotate, thereby driving the active gear to rotate. Under engagement, the adjusting gear is controlled to reverse, and then under the unidirectional action of the one-way bearing, the adjusting gear and the rotating shaft are locked to form a whole, controlling the reverse of the rotating shaft, driving the rotating shaft to rotate, and controlling the angle of the bottom vibration cam on the surface to adjust. After the adjustment, the adjusting motor stops working, and the vibration drive motor works in the air to control the rotation of the top vibration cam and the bottom vibration cam inside the vibration frame to generate adjusted vibration force to drive the steel casing to sink.

[0021] Step 3: When the steel casing is sinking, the lifting drive motor on the top is controlled to drive the soil-taking shaft to rotate, and the small sprocket is controlled to rotate. The four soil-taking shafts are controlled to move synchronously under the chain transmission, thereby driving the spiral lifting piece to rotate, and performing a spiral lifting operation on the mixed soil generated during the sinking of the steel casing.

[0022] Step 4. During the spiral lifting operation, the lifted soil is controlled to enter the interior of the L-shaped driving tube, and the vibration force transmission device is used to operate. The vibration frame vibrates while driving the bottom plate to apply vibration force to the bottom driving ring, thereby controlling the four telescopic driving shafts to reciprocate in the vertical direction, driving the bottom driving piston to reciprocate, and the sealing ball arranged on the top of the discharge pipe squeezes the sealing gasket and the spirally lifted soil and water inside the vertical soil taking pipe to form a closed control, thereby controlling the suction and thrust inside the L-shaped driving tube. The suction force extracts the lifted soil inside the vertical soil taking pipe, and the thrust pushes the top sealing ball to leave the sealing gasket so that the extracted soil can be discharged; until the steel casing finishes sinking, the vertical sliding block is pulled out through the vertical sliding groove for removal, leaving the steel casing.

[0023] The beneficial effects of the present invention are:

[0024] By arranging a sinking and earth-taking device, a vibrating sinking device, an automatic amplitude adjustment device and a vibration force transmission device, it is achieved that the steel casing can be simultaneously earth-taken during the sinking process, thereby improving the earth-taking efficiency and shortening the construction period; the automatic amplitude adjustment device can automatically adjust the amplitude according to construction requirements, thereby improving the accuracy and flexibility of construction; the vibration force transmission device transmits the vibration force of the vibrating sinking device to the sinking and earth-taking device, thereby realizing the vibration-force-driven earth-taking action and improving the earth-taking efficiency; the design of these devices realizes the automated construction during the sinking process of the steel casing, reduces the need for manual operation, and reduces labor intensity; through the simultaneous vibration and earth-taking, the disturbance of the surrounding soil by the single earth-taking operation is reduced, thereby maintaining the stability of the soil.

[0041] The top of the gripper 2 is respectively provided with a vibration sinking device 4, an amplitude automatic adjustment device 5 and a vibration force transmission device 6. In order to realize the action of providing a vibration driving force during the sinking of the steel casing 1, a vibration sinking device 4 is provided, including a vibration frame 41 installed on the top of the gripper 2. Guide sleeves 42 are fixedly installed on the tops of both ends of the vibration frame 41. Guide columns 43 are slidably inserted into the inner wall of the guide sleeves 42.

The tops of the four guide columns 43 are fixedly installed with arc-shaped protective covers 46, and the top hanging ears of the arc-shaped protective covers 46 are connected to the hooks of the lifting equipment.

[0042] Specifically implemented in this way, the design of the vibration frame 41 and the vibration spring 45 can provide continuous vibration power for the sinking of the steel casing 1, help overcome soil resistance, and accelerate the sinking speed; because guide sleeves 42 and guide columns 43 are installed at both ends of the vibration frame 41, and vibration springs 45 are installed on the bottom plate 44, this symmetrical design ensures that the vibration effect on the steel casing 1 is evenly distributed, which helps the steel casing 1 to sink smoothly.

The inner sides of the vibration frame 41 are rotatably connected to the inner walls via bearings with rotating shafts 410. The four rotating shafts 410 are grouped in pairs, and the two groups of rotating shafts 410 are arranged in parallel up and down.

[0044] Specifically, through the design of the power drive shaft 48 and the first pulley 49, the vibration can be evenly transmitted to the two sets of rotating shafts 410, ensuring that the vibration around the steel casing 1 is uniform, which helps the steel casing 1 to sink smoothly; through the upper and lower parallel arrangement of the two sets of rotating shafts 410, the stability of the entire vibrating sinking device 4 can be enhanced and the shaking during the vibration process can be reduced.

The four bottom vibration cams 415 are arranged crosswise, and a third pulley 417 is also fixedly installed at one end of one of the rotating shafts 410. The groove of the third pulley 417 and the groove of the second pulley 413 are both transmission-connected with a second belt 418.

[0048] Specifically implemented in this way, the top and bottom vibration cams work together to form a two-way vibration, which can more effectively break the adhesion and friction of the soil and improve the efficiency of the sinking of the steel casing 1; the coordinated use of the bottom vibration cam 415 and the top vibration cam 411 can enhance the effect of the vibration transmitted from the vibration frame 41 to the steel casing 1, making the sinking process smoother; through the two-stage belt transmission system, the first belt 414 and the second belt 418, the power of the vibration drive motor 47 can be more efficiently transmitted to the top and bottom rotating shafts 410.

[0049] In order to realize the action of automatic amplitude adjustment of the vibrating sinking device 4, an amplitude automatic adjustment device 5 is provided, which includes an L-shaped connecting seat 51 installed on the surface of one side of the vibration frame 41.

An adjusting gear 53 is fixedly installed on the outer arc surface of the one-way bearing 52.

[0050] Specifically, by adjusting the coordination between the gear 53 and the one-way bearing 52, the amplitude of the vibration sinking device 4 can be automatically adjusted to adapt to different construction requirements and environmental conditions; the automatic adjustment of the amplitude can quickly adapt to different soil conditions without stopping work for manual adjustment, thereby improving construction efficiency; by automatically adjusting the amplitude, the stability of the vibration sinking process can be maintained to avoid unstable sinking caused by excessive or small amplitude.

The bottom end of the telescopic driving shaft 63 penetrates and extends into the interior of the L-shaped driving tube 39, and a driving piston 64 is fixedly installed at the bottom end of the telescopic driving shaft 63. The surface of the driving piston 64 is slidably inserted with the inner wall of the L-shaped driving tube 39 through a sealing ring, and the tops of the four telescopic driving shafts 63 are fixedly installed with the bottom of the driving ring 62.

[0054] Specifically, the vibration force of the vibration sinking device 4 is converted into soil-extracting power through the vibration force transmission device 6, so that the vibration and soil-extracting can be carried out simultaneously, and the construction efficiency is improved; under the action of the vibration force, the driving piston 64 forms suction through the sliding connection between the sealing ring and the inner wall of the L-shaped driving tube 39, and cooperates with the spiral lifting piece 36 to more efficiently lift and transport the soil; the cooperation between the spiral lifting piece 36 and the driving piston 64 can realize the continuous lifting and transportation of the soil, avoiding the influence of the sinking efficiency due to the accumulation of soil.

[0055] A limiting sealing ring 65 is fixedly installed on the inner bottom side wall of the top end of the discharge pipe 310, a sealing gasket 66 is fixedly installed on the top end of the limiting sealing ring 65, a compression spring 67 is fixedly installed on the inner top side wall of the top end of the discharge pipe 310, a sealing ball 68 is fixedly installed on one end of the compression spring 67, and the surface of the sealing ball 68 is in extrusion contact with the surface of the sealing gasket 66.

[0056] Specifically implemented in this way, the compression spring 67 can maintain the continuous pressure of the sealing ball 68 on the sealing gasket 66, and maintain a good sealing effect even in the case of vibration or movement; through the cooperation of the compression spring 67 and the sealing ball 68, the internal space of the L-shaped drive tube 39 is sealed, ensuring the closed operation during the soil taking and discharge process, reducing the flying of soil and water loss; under the action of thrust, the sealing ball 68 leaves the sealing gasket 66, so that the soil can be discharged, while avoiding the backfilling of the soil into the discharge pipe 310, maintaining the continuity of the soil taking process; the compression spring 67 controls the sealing ball 68 to squeeze the sealing gasket 66 to seal, and cooperates with the spiral lifting plate 36 to achieve efficient soil discharge and speed up the construction progress.

[0057] By arranging the sinking soil-taking device 3, the vibrating sinking device 4, the automatic amplitude adjustment device 5 and the vibration force transmission device 6, the steel casing 1 can synchronously take soil during the sinking process, thereby improving the soil-taking efficiency and shortening the construction period; the automatic amplitude adjustment device 5 can automatically adjust the amplitude according to the construction requirements, thereby improving the accuracy and flexibility of the construction; the vibration force transmission device 6 transmits the vibration force of the vibrating sinking device 4 to the sinking soil-taking device 3, thereby realizing the vibration-force-driven soil-taking action and improving the soil-taking efficiency; the design of these devices realizes the automated construction during the sinking process of the steel casing 1, reduces the need for manual operation, and reduces labor intensity; through the synchronous vibration and soil taking, the disturbance of the surrounding soil by the single soil taking operation is reduced, thereby maintaining the stability of the soil.

[0058] Embodiment 2

[0059] Reference Figure 1-Figure 6 , a construction method for a vibration force transmission structure for large-diameter steel casing construction, step 1, during the sinking operation of the steel casing 1, the hook of the lifting equipment is connected to the hanging ear on the top of the arc-shaped protective cover 46 to drive the device to lift, and then the gripper 2 is used to clamp the steel casing 1. During the sinking, the vibration sinking device 4 works to control the vibration drive motor 47 to work, drive the power drive shaft 48 to rotate, thereby controlling the first pulley 49 at one end to rotate, and the first belt 414 connected to the surface transmission cooperates to drive the corresponding rotating shaft 410 at the bottom to rotate, and the rotating shaft The rotational motion of 410 controls the top vibration cam 411 and the top driving gear 412 on the surface to work, and the two top driving gears 412 mesh and work to synchronously control the two rotating shafts 410 on the top to rotate synchronously, driving the top vibration cam 411 on the surface to rotate and generate vibration force. At the same time, the second pulley 413 rotates and cooperates with the second belt 418 to control the rotational motion of the other corresponding rotating shaft 410 at the bottom, thereby controlling the rotational motion of the bottom vibration cam 415 to generate vibration force. The vibration force at the top and the vibration force at the bottom are combined to cooperate with the vibration steel casing 1 to sink.

[0060] Step 2: When the vibration amplitude needs to be adjusted according to the state of sinking, the vibration drive motor 47 stops working, so that the multiple rotating shafts 410 stop rotating. Because the adjusting gear 53 is internally installed with a one-way bearing 52, while the rotating shaft 410 rotates to generate vibration force, one end of the rotating shaft 410 performs idling motion with the adjusting gear 53 through the one-way bearing 52. When the adjusting gear 53 is stationary, the rotating shaft 410 rotates. When adjusting the amplitude, the adjusting motor 54 drives the adjusting shaft 55 to rotate, thereby driving the driving gear 56. Rotate, control the adjusting gear 53 to reverse under meshing, and then under the unidirectional action of the one-way bearing 52, the adjusting gear 53 and the rotating shaft 410 are locked to form a whole, control the rotating shaft 410 to reverse, drive the rotating shaft 410 to rotate, and control the angle of the bottom vibration cam 415 on the surface to adjust, and after the adjustment, the adjusting motor 54 stops working, and the vibration driving motor 47 works in the air, controlling the top vibration cam 411 and the bottom vibration cam 415 inside the vibration frame 41 to rotate, and generate the adjusted vibration force to drive the steel casing 1 to sink.

[0061] Step 3. When the steel casing 1 is sinking, the lifting drive motor 312 at the top is controlled to drive the soil-taking shaft 35 to rotate, and the small sprocket 37 is controlled to rotate. The four soil-taking shafts 35 are controlled to move synchronously under the transmission of the chain 38, thereby driving the spiral lifting piece 36 to rotate, and performing a spiral lifting operation on the mixed soil generated during the sinking of the steel casing 1.

[0062] Step 4, during the spiral lifting operation, the lifted soil is controlled to enter the interior of the L-shaped driving tube 39, and the vibration force transmission device 6 is used to operate. The vibration frame 41 vibrates while driving the bottom plate 44 to apply vibration force to the bottom driving ring 62, thereby controlling the four telescopic driving shafts 63 to reciprocate in the vertical direction, driving the bottom driving piston 64 to reciprocate, and the sealing ball 68 arranged on the top of the discharge pipe 310 squeezes the sealing pad 66 and the vertical soil extraction pipe 33 The spirally lifted soil and water are blocked to form a closed control, thereby controlling the L-shaped driving tube 39 to generate suction and thrust. The suction force extracts the soil lifted inside the vertical soil extraction pipe 33, and the thrust pushes the top sealing ball 68 to leave the sealing pad 66 so that the extracted soil is discharged; until the steel casing 1 sinks completely, the vertical sliding block 32 is pulled out through the vertical sliding groove 31 for removal, leaving the steel casing 1.

During the sinking, the vibration sinking device (4) works to control the vibration drive motor (47) to work, drive the power drive shaft (48) to rotate, thereby controlling the rotation of the first pulley (49) at one end, and the first belt (414) connected to the surface transmission cooperates to drive the corresponding rotation shaft (410) at the bottom to rotate, and the rotation of the rotation shaft (410) controls the surface The top vibration cam (411) and the top driving gear (412) work, and the two top driving gears (412) mesh and work to synchronously control the two rotating shafts (410) at the top to rotate synchronously, thereby driving the top vibration cam (411) on the surface to rotate and generate vibration force.

The vibration force at the top and the vibration force at the bottom are combined to cooperate with the vibration steel casing (1) to sink. Step 2: When the vibration amplitude needs to be adjusted according to the state of sinking, the vibration driving motor (47) stops working, so that the multiple rotating shafts (410) stop rotating. Since the adjusting gear (53) is internally installed with a one-way bearing (52), when the rotating shaft (410) rotates to generate vibration force, one end of the rotating shaft (410) performs idling motion with the adjusting gear (53) through the one-way bearing (52). When the adjusting gear (53) is stationary, the rotating shaft (410) rotates.

After the adjustment is completed, the adjusting motor (54) stops working, and the vibration driving motor (47) in the air works to control the top vibration cam (411) and the bottom vibration cam (415) inside the vibration frame (41) to rotate, thereby generating an adjusted vibration force to drive the steel casing (1) to sink; Step 3: When the steel casing (1) is sinking, the lifting drive motor (312) at the top is controlled to work to drive the soil taking shaft (35) to rotate, and the small sprocket (37) is controlled to rotate. The four soil taking shafts (35) are synchronously controlled to move synchronously under the transmission of the chain (38), thereby driving the spiral lifting piece (36) to rotate, and performing a spiral lifting operation on the mixed soil generated during the sinking of the steel casing (1); Step 4: During the spiral lifting operation, the lifted soil is controlled to enter the interior of the L-shaped driving tube (39), and the vibration force transmission device (6) is operated to drive the bottom plate (44) to apply vibration force to the bottom driving ring (62) through the vibration of the vibration frame (41), thereby controlling the four telescopic driving shafts (63) to reciprocate in the vertical direction, driving the bottom driving piston (64) to reciprocate, and the sealing ball (68) provided at the top of the discharge tube (310) squeezes the sealing pad (66 ) and the vertical soil taking pipe (33) to block the soil and water lifted by the spiral, forming a closed control, thereby controlling the suction and thrust inside the L-shaped driving pipe (39), the suction extracts the soil lifted inside the vertical soil taking pipe (33), and the thrust pushes the sealing ball (68) at the top to leave the sealing pad (66) so that the extracted soil can be discharged; until the steel casing (1) sinks completely, the vertical sliding block (32) is pulled out through the vertical sliding groove (31) for removal, leaving the steel casing (1).
