In the method, the first material dividing port is connected with the chute, so that the conveying mechanism can provide stones for the leveling mechanism; the lower blanking pipe is driven to be far away from the leveling machine frame through the leveling telescopic device; so that the lower blanking pipe is communicated with the upper blanking pipe; meanwhile, when the pipeline is laid on the seabed, the seabed foundation bed needs to be leveled first, then the pipeline is placed, and then the pipeline is locked; finally, burying; the leveling feeding channel is communicated with the first distributing port by controlling the swinging direction of the first distributing part; then the conveying mechanism outputs stone, and at the moment, the stone output from the first material distribution port can enter the leveling material feeding channel; then, the leveling moving piece drives the leveling machine frame to move, and the leveling of the foundation bed is realized in the moving process; when the leveling of one foundation bed is finished, the leveling moving piece drives the leveling rack to reset, so that the locking device can conveniently lock the pipe body when moving from the initial end to the tail end of the leveled foundation bed; meanwhile, the blanking pipe at the lower part is close to the leveling frame; when the pipeline is locked, the leveling device and the locking device both need to move along the moving direction of the leveling moving device, and the pipeline is locked after the pipe body is placed; the pipe body is placed above the stone material which is leveled, namely the moving directions of the pipe body and the leveling blanking pipe are consistent; the impact between the movement of the leveling blanking pipe and the pipe body is avoided; the leveling telescopic device drives the blanking pipe at the lower part to retract, so that the safety is high; meanwhile, the phenomenon that the leveling moving piece cannot move due to the fact that the blanking pipe at the lower part is contacted with the pipe body is avoided; hoisting the leveling mechanism to be far away from the foundation bed which is leveled; thus being convenient for placing the pipeline; after the pipeline is placed, hoisting the leveling mechanism to the position above the pipeline; then, communicating and locking a feeding channel to communicate with a first material distributing opening by controlling the swinging direction of the first material distributing part; then the conveying mechanism outputs stone, and the stone output from the first material distribution port can enter the locking feeding channel at the moment; then, the leveling moving piece drives the leveling rack to move, and the pipeline is locked in the moving process; after the pipeline on one foundation bed is locked; hoisting the leveling mechanism to the position above the next foundation bed to be leveled, continuously leveling the foundation bed at the position, and then repeatedly placing the pipeline and locking the pipeline; after all pipelines in the construction area are locked, the first material distribution port is separated from the chute, and the leveling mechanism is hoisted to the ship body; when the construction area is constructed, the leveling mechanism is only required to be hoisted twice from the ship body to the construction area, so that the leveling frame is prevented from being hoisted to the construction area frequently from the ship body; save the engineering time, it is efficient.
Further, the chute and the leveling moving member move synchronously.
Through the arrangement, the chute and the leveling moving piece can move synchronously; when the leveling moving member moves to backfill and lock the lock, the chute can also supply materials for the leveling mechanism.
Furthermore, the supporting piece and the first material distribution driving device are oil cylinders.
Above setting, support piece and first branch material drive arrangement's simple structure, convenient control.
Further, in the step 1), when the leveling mechanism moves towards the foundation bed to be leveled, the supporting piece stretches out, and the supporting piece drives the supporting foot to be far away from the leveling support. By arranging the supporting piece, the distance between the supporting foot and the leveling bracket can be adjusted; thereby adjusting the distance between the leveling bracket and the supporting surface; thus facilitating construction; when the leveling mechanism reaches the upper part of the base bed, the lower blanking pipe is far away from the leveling machine frame; the distance between the leveling bracket and the supporting surface is prolonged through the supporting piece, so that the distance between the blanking pipe at the lower part and the supporting surface is also prolonged; thus avoiding the impact between the blanking pipe at the lower part and the supporting surface; meanwhile, when the leveling mechanism moves towards the foundation bed to be leveled, the supporting piece extends out; in this way, the distance adjustment is effected before the foot comes into contact with the support surface; the construction time is saved.
Further, in step 10), when the leveling mechanism moves towards the ship body, the supporting piece retracts, and the supporting piece drives the supporting foot to be close to the leveling support. Thus, the resetting of the arm brace is realized.
Further, in step 3): the first material distribution driving device extends out and drives the first material distribution piece to swing towards the locking feeding channel; the leveling feeding channel is communicated with the first material distributing opening. The first material distributing driving device drives the first material distributing part to swing, and the structure is simple.
Further, step 7): the first material distribution driving device retracts, and drives the first material distribution piece to swing towards the leveling material feeding channel; the locking feeding channel is communicated with the first material distributing opening. The first material distributing driving device drives the first material distributing part to swing, and the structure is simple.
Further, the embedding in step 10) includes the following specific steps:
(10.1) driving a hoisting driving motor; hoisting the moving piece to drive the chute to move to the starting end of the construction area;
(10.2) outputting stones by the material conveying mechanism;
(10.3) moving the hoisting moving piece along the guide direction of the hoisting guide rail;
(10.4) hoisting the moving piece to drive the chute to move to a finishing end of a construction area; the material conveying mechanism stops outputting stones; burying a construction area;
(10.5) judging whether all construction areas are buried completely; if so, completing construction; if not, the ship body moves to the downward movement construction area, and then the step (10.1) is repeated.
According to the method, the movable piece is lifted to drive the chute to move so as to realize burying, and the operation is convenient.

(10.3) moving the hoisting moving piece along the guide direction of the hoisting guide rail;
(10.4) hoisting the moving piece to drive the chute to move to a finishing end of a construction area; the material conveying mechanism stops outputting stones; burying a construction area;
(10.5) judging whether all construction areas are buried completely; if so, completing construction; if not, the ship body moves to the downward movement construction area, and then the step (10.1) is repeated.
