[0020] The construction process of the stone throwing, ramming, and leveling integrated ship with the functions of stone throwing, ramming, and leveling includes the following steps:

[0021] S1: Stone throwing process

[0022] S11: After the stone ramming integrated ship is loaded with stones, it is winched and moved above the rockfill foundation and positioned on the underwater foundation to be constructed.

[0023] S12: Turn on the automatic pressure regulating ballast system to automatically level the ship.

[0024] S13: Lower the rockfill chute device into the water, fix it below the rockfill hopper with a pin shaft, and lower the telescopic sleeve to the specified depth.

[0025] Control method for lowering the rockfill chute device:

[0026] Retract the wire rope of the second chute winch, lift the telescopic sleeve through the lifting frame, pull out the locking pin, rotate the typhoon prevention shelf so that it rotates along the shaft to the ship's side, and insert the locking pin; release the wire rope of the second chute winch until the telescopic sleeve is in a natural hanging state; release the wire rope of the small winch fixed on the boom, fix the wire clamp connected to the hook head on the wire rope of the second chute winch and lock it, use the wire rope of the small winch to retract, pull the wire rope of the second chute winch out of the groove of the single-sheave pulley, lower the wire rope of the small winch until the wire rope of the second chute winch is in a tension-free state; disassemble the wire clamp and retract the wire rope of the small winch; tighten the wire rope of the first chute winch until all the eye plates at the top of the telescopic sleeve are aligned, insert the pin shaft, and tighten the wire rope of the second chute winch.

[0027] Control method for telescoping the rockfill chute device:

[0028] Tighten the wire ropes of the first chute winch and the second chute winch, switch to the linkage synchronous control program of the two winches, and automatically fine-tune the tension of the two winches; the inner sleeve of the telescopic sleeve is fixed to the feeding port through the eye plate, pull out the pin shafts on both sides of the telescopic sleeve, and link to lower or retract the wire ropes of the first chute winch and the second chute winch, and the outer sleeve of the telescopic sleeve will be lowered or retracted accordingly.

[0029] S14: Use an excavator in the material storage cabin to dump stones into the rockfill hopper.

[0030] S15: Move the rockfill trolley structure through the cable system to complete rockfill in the specified underwater area.

[0031] When the rockfill trolley moves under the C-shaped track, after the ramming platform trolley rotates outwards from the inside to the outside together with the short track, the track is locked and the wire rope of the recovery winch is disassembled; the cable connection relationship for the movement of the rockfill trolley is: the wire rope of the first traction winch passes through the first single-sheave pulley, the second single-sheave pulley, and the third single-sheave pulley, and then passes through the bottom of the ramming platform trolley and is directly connected to the first fixed eye plate of the rockfill trolley; the wire rope of the second traction winch is directly connected to the second fixed eye plate of the rockfill trolley.

[0032] S2: Ramming process

[0033] S21: Release the anti-wind zipper of the ramming platform vehicle, remove the limit locking plate, rotate the short track through the cable system to dock and lock with the C-shaped track, and move the ramming platform vehicle to the C-shaped track;

[0034] When the ramming platform vehicle rotates outwards from the inside to the outside, the cable connection relationship is as follows: the steel wire rope of the No. 1 traction winch passes through the No. 1 single-sheave pulley, the No. 2 single-sheave pulley, the No. 1 triple-sheave pulley set, and the No. 3 triple-sheave pulley set, and then the rope end is fixed on the base of the No. 1 triple-sheave pulley set; when rotating inwards from the outside to the inside, the cable connection relationship is that the steel wire rope of the No. 1 traction winch passes through the No. 1 single-sheave pulley, the No. 2 single-sheave pulley, the No. 2 triple-sheave pulley set, and the No. 3 triple-sheave pulley set, and then the rope end is fixed on the base of the No. 2 triple-sheave pulley set;

[0035] S22: Lower the ramming conduit so that the rammer plate lands on the top surface of the dumped stones. Turn on the vibratory hammer power unit of the ramming platform vehicle structure, and adjust the exciting force of the hydraulic vibratory hammer to carry out the ramming operation;

[0036] S23: After the ramming operation of one layer is completed, move the stone-dumping trolley to carry out the stone-dumping and ramming processes for the second layer of the foundation until the levelable elevation is reached;

[0037] S3: Levelling process

[0038] S31: Move the ramming platform vehicle on the C-shaped track, and use the follow-up control technology of the ramming system program to set the pre-tightening force of the ramming winch;

[0039] Under the condition that the ramming platform vehicle moves on the C-shaped track, the cable connection relationship for the movement of the ramming platform vehicle is as follows: after the ramming platform vehicle rotates outwards from the inside to the outside together with the short track, the track is locked, the steel wire rope of the No. 1 traction winch is disassembled and retracted, and the steel wire rope of the No. 1 traction winch passes through the No. 1 single-sheave pulley, the No. 2 single-sheave pulley, the No. 3 single-sheave pulley and the No. 1 guiding pulley of the ramming platform vehicle and is then fixed on the No. 1 fixed cable ear; the steel wire rope of the No. 2 traction winch directly passes through the No. 2 guiding pulley of the ramming platform vehicle and is then fixed on the No. 2 fixed cable ear;

[0040] S32: Turn on the vibratory hammer to work with a small exciting force, and the two ramming winches release the steel wire ropes synchronously in linkage. When the ramming conduit descends to the designed elevation, the ramming winches automatically stop, so that the rammer plate is fixed at a constant elevation position;

[0041] S33: Carry out the construction of constant elevation at all points through the overlapping of the rammer plates to complete the foundation leveling and meet the construction technical standards for directly installing upper structures such as caissons;

[0042] S4: Retrieval of the stone-dumping chute device and the ramming platform vehicle

[0043] S41: Control method for retracting the stone-dumping chute device:

[0044] The chute winch 1 and the chute winch 2 are symmetrically fixed on the bottom surface of the trolley of the rock-throwing chute device from left to right. After the steel wire ropes of the two winches are wound around the corresponding universal fairleads 1 and 2, the steel wire ropes are respectively fixed on the bottom lifting lugs of the telescopic sleeve. Remove the three fixed pin shafts on the outside of the eye plate at the top of the telescopic sleeve, release the steel wire ropes of the chute winch 1 and the chute winch 2, and the telescopic sleeve is in a natural drooping state connected by one pin shaft. Release the steel wire rope of the small winch fixed on the suspension rod. The hook head of this steel wire rope is connected to the steel wire clamp, fix the steel wire clamp on the steel wire rope of the chute winch 2 and lock it. Use the steel wire rope of the small winch to recover, and tow the steel wire rope of the chute winch 2 to the single-sheave pulley fixed on the lifting bracket. Release the steel wire rope of the chute winch 1, recover the steel wire rope of the chute winch 2, and lift the telescopic sleeve to the maximum height. Pull out two locking pins and rotate the two typhoon prevention shelves outwards to the ship's side until they are limited by the limit blocks. Release the steel wire rope of the chute winch 2, place the telescopic sleeve on the typhoon prevention shelf, insert the locking pins, and fix the pipe clamp.

[0045] When the ramming platform trolley is retracted from the outside to the inside, the cable connection relationship is the same as when it is rotated out from the inside to the outside. After the ramming platform trolley is rotated into the inside together with the short track, the short track is locked, and the steel wire rope of the No. 1 traction winch is disassembled and recovered. At this time, under the condition that the rock-throwing trolley moves on the C-shaped track, its cable connection relationship is: the steel wire rope of the No. 1 traction winch passes through the No. 1 single-sheave pulley and the No. 2 single-sheave pulley, passes through the gap between the short track and the C-shaped track, and is directly connected to the No. 1 fixed eye plate of the rock-throwing trolley after passing through the No. 4 single-sheave pulley; the steel wire rope of the No. 2 traction winch is directly connected to the No. 2 fixed eye plate of the rock-throwing trolley.

[0046] The No. 1 single-sheave pulley is arranged perpendicular to the main deck surface along the direction of the steel wire rope, more than 5 m away from the No. 1 traction winch. Its function is to be not affected by the change of the rope-out angle of the steel wire rope on the drum of the No. 1 traction winch, and always limit and keep the passing steel wire rope in a parallel state; the No. 2 single-sheave pulley is arranged horizontally, 3 m away from the No. 1 single-sheave pulley. The connection line between the center line of the outer wheel groove of the No. 2 single-sheave pulley and the center line of the upper wheel groove of the No. 1 single-sheave pulley is horizontal with the main deck; both the No. 2 triple-sheave pulley group and the No. 3 triple-sheave pulley group are arranged horizontally, and the lower sheaves of the pulley groups are at the same height from the main deck as the No. 2 single-sheave pulley; the No. 1 guide pulley of the ramming platform trolley and the No. 2 guide pulley of the ramming platform trolley are both arranged at the bottom of the truss of the ramming platform trolley, and their connection line coincides with the center line of the track; the No. 3 single-sheave pulley is located 4 m outside the short track, parallel to the No. 1 and No. 2 guide pulleys of the ramming platform trolley, and at the same height from the main deck; the No. 4 single-sheave pulley is located on the center line between the tracks at the connection of the C-shaped track and the short track, and its height is lower than the No. 1 and No. 2 guide pulleys of the ramming platform trolley to prevent the ramming platform trolley from being restricted when moving; the connection line between the No. 4 single-sheave pulley and the No. 2 single-sheave pulley forms an angle less than 6° with the horizontal direction.

[0047] The follow-up control specifically adopts the following method:

[0048] When the stone-throwing trolley or the ramming platform trolley moves on the C-shaped track, the follow-up technology is applied. These two working conditions are front and back processes and do not move simultaneously. The first traction winch and the second traction winch are both driven by frequency conversion motors. In the follow-up mode, in the frequency conversion control cabinets of the first traction winch and the second traction winch, the brake brakes of the two winches are interlocked and controlled. The interlocked control is that when the frequency conversion motor of the first traction winch is powered on, the brake of the first traction winch is powered on and disengaged, and at the same time, the brake of the second traction winch is also interlocked and powered on and disengaged. The motor of the first traction winch drives the winch to operate and tow the trolley to move. At the same time, the cable of the second traction winch is passively towed and follows. For the cable of the second traction winch being passively towed and following, its frequency conversion motor rotates followingly under the external force transmission of the drum and the gearbox. When the motor of the second traction winch rotates followingly, regenerative electric energy will be generated, and energy consumption braking is carried out by installing a discharge resistor unit component on the DC side of the frequency converter. The energy consumption braking includes two parts: a braking unit and a braking resistor. The resistance of the braking cancels out part of the rotational inertia of the cable of the second traction winch being towed, preventing the drum of the second traction winch following from continuing to rotate and causing rope jamming when the first traction winch decelerates or stops. The principle of the second traction winch driving the cable to move the trolley and the first traction winch following is the same as above.

[0049] The follow-up control technology is brake interlock control. The control of the two traction winches includes individual local operation, remote single control, and remote linkage control.

[0050] A ramming and leveling integrated ship with the functions of stone throwing, ramming, and leveling of the present utility model breaks through the design deficiencies of the prior art, innovatively utilizes the drive of two winches and the conversion of the cable system, realizes the movement of the ramming platform trolley and the stone-throwing trolley on the same side track, and at the same time, only uses one winch to tow the short track and the ramming platform trolley to rotate into or out of the main deck integrally, improving the safety of the ramming platform trolley; after optimizing multiple winches, the total power configuration of the ship is reduced, effectively saving the construction cost. Most importantly, by reducing the number and layout position of the trolleys, the working length of the track is increased, the construction distance of the trolley on the underwater foundation working section is increased, and the storage area of the storage bin on the main deck of the ship is effectively increased, greatly improving the production efficiency and significantly saving the construction and maintenance costs. At the same time, the innovatively applied follow-up control technology solves the control technology problems of similar equipment in the industry and fills the gap; the present utility model only uses one ship to continuously complete all the processes of underwater foundation construction, reducing the combined input production cost of 2-3 ships for single-process construction in the past, as well as the ship towing cost. More importantly, it saves the waiting cost of multiple ships for cross-operation, effectively improves the production efficiency, and significantly improves the economy.

[0106] The following specific method is adopted for the follow-up control:

[0107] The follow-up technology is applied to the moving conditions of the stone throwing trolley 3 or the ram platform vehicle 2 on the C-shaped track 4. These two conditions are sequential processes and do not move simultaneously; the first traction winch 41 and the second traction winch 42 are both driven by frequency conversion motors. In the follow-up mode, in the frequency conversion control cabinets of the first traction winch 41 and the second traction winch 42, the brake brakes of the two winches are interlocked; the interlock control is that when the frequency conversion motor of the first traction winch 41 is powered on, the brake of the first traction winch 41 is powered on and disengaged, and at the same time, the brake of the second traction winch 42 is also interlocked and powered on and disengaged; the motor of the first traction winch 41 drives the winch to operate and tow the trolley to move, and at the same time, the cable of the second traction winch 42 is passively towed and follows; for the cable of the second traction winch 42 being passively towed and following, its frequency conversion motor rotates following due to the external force transmission of the drum and the gearbox. The follow-up rotation of the motor of the second traction winch 42 will generate regenerative electric energy, and energy consumption braking is carried out by installing a discharge resistor unit component on the DC side of the frequency converter; the energy consumption braking includes two parts: a braking unit and a braking resistor. The braking resistance offsets a part of the rotational inertia of the cable of the second traction winch 42 being towed, preventing the drum of the second traction winch 42 following from continuing to rotate and causing rope chaos when the first traction winch 41 decelerates or stops; the principle of the second traction winch 42 driving the cable to move the trolley and the first traction winch 41 following is the same as above.

[0108] The follow-up control technology is brake interlock control, and the control of two traction winches includes individual local operation, remote single control, and remote linkage control.
