[0040] The present invention also includes 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.

[0041] The present invention is used in combination with a riprap ship, which is provided with a crane, a conveying mechanism for conveying stones, and a chute for conveying stones (not shown in the figure). The method of use includes the following steps:

[0042] 1). Use a crane to hoist the leveling mechanism to a base bed to be leveled in the construction area;

[0043] 2). The first material distribution port is connected to the chute of the riprap ship; the leveling telescopic device drives the lower material distribution pipe away from the leveling frame; and the leveling limit piece is installed;

[0044] 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;

[0045] 4). The riprap ship outputs stones, and the stones fall 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);

[0046] 5). The riprap ship stops discharging stones and removes the leveling limiter; the leveling moving part 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 chute of the riprap ship; the crane on the riprap ship hoists the leveling mechanism away from the leveled bed; after the hoisting is completed, proceed to step 6);

[0047] 6). The crane on the riprap ship hoists the pipe onto the leveled base bed, and then the crane hoists the leveling mechanism onto the base bed. The pipe locking and material distribution channels are located on both sides of the pipe; the first material distribution port 131 is connected to the slide pipe;

[0048] 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;

[0049] 8). The riprap ship outputs stones, and the stones pass through the first material distribution port, the locked material feeding channel, and then fall 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 riprap ship stops outputting stones, and the first material distribution port is separated from the chute of the riprap ship; proceed to step 9);

[0050] 9). The crane on the riprap ship 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 chute of the riprap ship; the leveling telescopic device drives the lower material distribution pipe away from the leveling frame; the leveling limit piece is installed; and then step 3 is repeated); all pipelines in the construction area are locked.

[0051] The above method;

[0052] 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.

[0053] 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 riprap ship, 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.

[0054] 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.

[0055] Step 5) specifically includes: removing the leveling limiter 147 between the leveling limiter 1 146 and the leveling limiter 2 148 .

[0056] Step 6) is specifically as follows: placing the pipeline on the pipeline support; and then hoisting the pipeline support with a crane, so that the pipeline support and the pipeline are hoisted onto the leveled base bed.

[0057] 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.

[0058] Step 8) is specifically: lock the stones that fall from the material distribution channel to lock the pipes and pipe supports. In the construction area, when the next pipe is not placed, the end of the pipe is not 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;

[0059] 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 riprap ship stops outputting stones, and the first material distribution port is separated from the chute of the riprap ship; proceed to step 9)

[0060] 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 riprap ship stops outputting stones, and the first material distribution port is separated from the chute of the riprap ship; proceed to step 9); this makes it convenient to connect the pipelines in the construction area.

[0061] Step 9) is specifically as follows: the crane 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 chute of the riprap ship; 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) to 5); then proceed to step 9.1);

[0062] 9.1). The crane hoists the pipe to the leveled base bed;

[0063] 9.2). The pipeline to be locked is connected to the locked pipeline;

[0064] 9.3). The crane then hoists 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 chute of the riprap ship;
