The present invention further comprises an underwater camera (not shown in the figure); the structure of the underwater camera is prior art and will not be described again here. The underwater camera is arranged at the bottom of the leveling mechanism 1 .

[0062] The construction method of the present invention comprises the following steps:

[0063] 1). The lifting mechanism hoists the leveling mechanism to one of the base beds to be leveled in the construction area;

[0064] 2). The first material distribution port is connected to the slide pipe; the leveling telescopic device drives the lower material distribution pipe away from the leveling frame; the leveling limit piece is installed;

[0065] 3). The first material distribution member swings toward the locking feed channel; the feed channel is leveled and connected to the first material distribution port;

[0066] 4). The feeding mechanism outputs the stone, and the stone falls from the leveling feeding channel through the first material distribution port; the leveling moving part drives the leveling frame to move; the base bed to be leveled is leveled along the moving direction of the leveling moving part, and after the base bed is leveled, step 5 is performed);

[0067] 5). The feeding mechanism stops feeding the stone, and the leveling limiter is removed; the leveling moving member drives the leveling frame to reset, and the leveling telescopic device 144 drives the lower feeding pipe 143 close to the leveling frame; the first material distribution port 131 is separated from the slide pipe; the lifting mechanism lifts the leveling mechanism away from the leveled base bed; after lifting, proceed to step 6);

[0068] 6). The lifting mechanism lifts the pipeline onto the leveled base bed, and then the lifting mechanism lifts the leveling mechanism onto the base bed. The pipeline locking and material distribution channels are located on both sides of the pipeline; the first material distribution port 131 is connected to the slide pipe;

[0069] 7). The first material distribution member 161 swings toward the leveling feed channel; the feed channel 153 is locked and connected to the first material distribution port 131;

[0070] 8). The feeding mechanism outputs the stone, and the stone passes through the first material distribution port, the locked material feeding channel, and then falls from the two locked material distribution channels; the leveling moving part drives the leveling frame to move; the pipeline is locked along the moving direction of the leveling moving part; after the pipeline is locked, the feeding mechanism stops outputting the stone, and the first material distribution port is separated from the chute; proceed to step 9);

[0071] 9). The lifting mechanism hoists the leveling mechanism to the next base bed to be leveled in the construction area; the first material distribution port is connected to the slide pipe; the leveling telescopic device drives the lower material distribution pipe away from the leveling frame; the leveling limiter is installed; and then step 3 is repeated); when all pipelines in the construction area are locked, step 10 is performed);

[0072] 10). The lifting mechanism lifts the leveling mechanism onto the hull; the feeding mechanism outputs the stone; the stone falls from the chute to the construction area for burial.

[0073] The above construction method; in step 4), step 5), step 8); the slide pipe and the leveling moving member move synchronously; the slide pipe 222 and the unloading trolley are driven to move by the lifting moving member 312;

[0074] In step 1), when the leveling mechanism moves toward the base bed to be leveled, the support extends, and the support drives the support foot away from the leveling bracket. By setting the support, the distance between the support foot and the leveling bracket can be adjusted, thereby adjusting the distance between the leveling bracket and the support surface, which is convenient for construction. Also, when the leveling mechanism is above the base bed, the lower feeding pipe is away from the leveling frame, and the distance between the leveling bracket and the support surface is extended by the support, so that the distance between the lower feeding pipe and the support surface is also extended, thus avoiding the collision between the lower feeding pipe and the support surface. At the same time, when the leveling mechanism moves toward the base bed to be leveled, the support extends, thus achieving distance adjustment before the support foot contacts the support surface, saving construction time.

[0075] Step 2) specifically includes: installing a leveling stopper 147 between the leveling stopper 146 and the leveling stopper 2. When the leveling mechanism moves toward the hull, the support member retracts, and the support member drives the support leg to approach the leveling bracket, so as to achieve the reset of the support leg.

[0076] Step 3) specifically includes: extending the first material distribution driving device, driving the first material distribution member to swing toward the locking feed channel; and leveling the feed channel to communicate with the first material distribution opening. The first material distribution member is driven to swing by the first material distribution driving device, and the structure is simple.

[0077] Step 5) specifically includes: removing the leveling limiter 147 between the leveling limiter 1 146 and the leveling limiter 2 148 .

[0078] Step 6) is specifically as follows: placing the pipeline on the pipeline support; and then hoisting the pipeline support with a lifting device, so that the pipeline support and the pipeline are hoisted onto the leveled base bed.

[0079] Step 7) specifically includes: the first material distribution drive device is retracted, and the first material distribution drive device drives the first material distribution piece to swing toward the leveling feed channel; the feed channel is locked and connected to the first material distribution port. The first material distribution drive device drives the first material distribution piece to swing, and the structure is simple.

[0080] Step 8) is specifically as follows: lock the stones that fall from the material distribution channel to lock the pipe and the pipe support. In the construction area, when the next pipe is not placed, the end of the pipe will not be locked. Specifically: preset a locking stop distance according to the length between the leveling moving part and the end of the pipe; and use the underwater camera to determine whether the currently locked pipe is the last pipe in the construction area. The last pipe is the last pipe connected end to end in the construction area;

[0081] If not: start locking from the end of the previous pipeline locking; the leveling moving part moves; when the length between the leveling moving part and the end of the current pipeline matches the locking stop distance; the leveling moving part stops moving; at this time, after the pipeline is locked, the feeding mechanism stops outputting stones, and the first material distribution port is separated from the chute; proceed to step 9)

[0082] If: start locking from the end of the previous pipeline locking; the leveling moving part drives the leveling frame to move; lock the entire pipeline along the moving direction of the leveling moving part; after the pipeline locking is completed, the feeding mechanism stops outputting stones, and the first material distribution port is separated from the chute; proceed to step 9); this makes it convenient to connect the pipelines in the construction area.

[0083] Step 9) is specifically as follows: the lifting mechanism hoists the leveling mechanism to the next base bed to be leveled in the construction area; the first material distribution port is connected to the slide pipe; the leveling telescopic device drives the lower material distribution pipe away from the leveling frame; the leveling limiter 147 is installed between the leveling limiter 146 and the leveling limiter 2; then repeat steps 3)-5); then proceed to step 9.1);

[0084] 9.1). The lifting mechanism lifts the pipe to the leveled base bed;

[0085] 9.2). The pipeline to be locked is connected to the locked pipeline;

[0086] 9.3). The lifting mechanism then lifts the leveling mechanism onto the base bed of the locked pipeline; the pipeline locking and material distribution channels are located on both sides of the pipeline; the first material distribution port is connected to the slide pipe;

[0087] 9.4). The first material distribution piece swings toward the leveling feed channel; the feed channel is locked and connected to the first material distribution port; then repeat step 8); when all pipelines in the construction area are locked, proceed to step 10).

[0088] Step 10) is specifically as follows: determine whether all pipelines in all construction areas have been locked; if so, the lifting mechanism lifts the leveling mechanism onto the hull; the material conveying mechanism outputs the stone; the stone falls from the slide pipe to the construction area for burial. If not; the lifting mechanism lifts the leveling mechanism to the next construction area and repeats step 1).

[0089] The specific steps for burying are:

[0090] (10.1). The lifting drive motor drives; the lifting moving member 312 drives the slide pipe 222 to move to the starting end of the construction area;

[0091] (10.2). The conveying mechanism outputs the stone;

[0092] (10.3). The lifting moving member 312 moves along the guide direction of the lifting guide rail 311;

[0093] (10.4). The lifting moving member 312 drives the slide pipe 222 to move to the end of the construction area; the feeding mechanism stops outputting stones; and the burial of one construction area is completed;

[0094] (10.5). Use the underwater camera to determine whether all construction areas have been buried; if so, the construction is completed; if not, the hull moves to the lower construction area and then repeats step (10.1).

[0095] The above method is connected with the slide pipe through the first material distribution port, so that the conveying mechanism can provide stones for the leveling mechanism; the lower material distribution pipe is driven away from the leveling frame by the leveling telescopic device; so that the lower material distribution pipe is connected with the upper material distribution pipe; at the same time, because it is necessary to level the seabed first when laying pipelines on the seabed, and then place the pipelines, and then lock the pipelines; finally bury them; by controlling the swing direction of the first material distribution part, the leveling feeding channel is connected with the first material distribution port; then the conveying mechanism outputs the stones again, and at this time the stones output from the first material distribution port can enter the leveling feeding channel; then the leveling moving part drives the leveling frame to move, and in the moving The base bed is leveled during the process; when a base bed is leveled, the leveling moving part drives the leveling frame to reset, so that it is convenient for the locking device to lock the pipe body when it moves from the beginning to the end of the leveled base bed; at the same time, the lower feeding pipe approaches the leveling frame; because when locking the pipe, the leveling device and the locking device need to move along the moving direction of the leveling moving device, and the locking of the pipe is carried out after the pipe body is placed; and because the pipe body is placed above the leveled stone, that is, the moving direction of the pipe body and the leveling feeding pipe is consistent; in order to avoid the collision between the moving leveling feeding pipe and the pipe body; the lower feeding pipe is driven by the leveling telescopic device The drop pipe is retracted, which is safer. At the same time, it avoids the contact between the lower drop pipe and the pipe body, which makes it impossible for the leveling moving part to move. The leveling mechanism is hoisted away from the leveled base bed. This makes it convenient to place the pipeline. When the pipeline is placed, the leveling mechanism is hoisted above the pipeline. Then, by controlling the swing direction of the first material dividing piece, the locking feed channel is connected to the first material dividing port. Then the conveying mechanism outputs the stone again, and the stone output from the first material dividing port can enter the locking feed channel. Then the leveling moving part drives the leveling frame to move, and the pipeline is locked during the movement. When the pipeline on a base bed is locked, the whole The leveling mechanism is hoisted to the top of the next base bed to be leveled to continue leveling the base bed at that location, and then the steps of placing and locking the pipes are repeated; when all the pipes in the construction area are locked, the first material distribution port is separated from the slide pipe, and the leveling mechanism is hoisted onto the hull; in this way, when constructing the construction area, it is only necessary to hoist the leveling mechanism from the hull to the construction area twice, thus avoiding frequent hoisting of the leveling frame from the hull to the construction area, saving construction time, and then using the lifting mechanism to move the slide pipe to bury the pipeline. Since the lifting mechanism is arranged above the leveling mechanism, the lifting mechanism will not be affected when moving on the ship.
