The method;
in the step 1), when the leveling mechanism moves towards the foundation bed to be leveled, the supporting piece stretches out and drives the supporting feet to be far away from the leveling support. The distance between the support legs and the leveling support can be adjusted by arranging the supporting pieces, so that the distance between the leveling support and the supporting surface is adjusted, construction is convenient, the distance between the leveling support and the supporting surface is prolonged by extending the distance between the leveling support and the supporting surface through the supporting pieces after the leveling mechanism is arranged above the base bed, impact between the lower blanking pipe and the supporting surface is avoided, meanwhile, when the leveling mechanism moves towards the base bed to be leveled, the supporting pieces extend out, distance adjustment is achieved before the support legs are contacted with the supporting surface, and construction time is saved.
Step 2) is specifically that a leveling limiting piece 147 is arranged between the leveling limiting part I146 and the leveling limiting part II. When the leveling mechanism moves towards the stone throwing ship, the supporting piece is retracted, and the supporting piece drives the supporting feet to be close to the leveling support. This achieves a reset of the temple.
The step 3) comprises the steps that the first material distributing driving device stretches out and drives the first material distributing piece to swing towards the locking material feeding channel, and the leveling material feeding channel is communicated with the first material distributing opening. The first material distributing driving device drives the first material distributing piece to swing, and the structure is simple.
Step 5) is specifically to detach the leveling limiting piece 147 between the leveling limiting part one 146 and the leveling limiting part two 148.
Step 6) is that the pipeline is placed on the pipeline support, and then the crane is used for hoisting the pipeline support, so that the pipeline support and the pipeline are hoisted on the flattened foundation bed.
The step 7) comprises the steps that the first material distributing driving device retracts, the first material distributing driving device drives the first material distributing piece to swing towards the leveling material inlet channel, and the material inlet channel is locked and communicated with the first material distributing opening. The first material distributing driving device drives the first material distributing piece to swing, and the structure is simple.
And step 8), locking the stone falling from the material distributing channel to lock the pipeline and the pipeline support. In the construction area, the ends of the pipe are not locked when the next pipe is not placed. The method comprises the steps of presetting a locking stopping distance according to the length between a leveling moving piece and the tail end of a pipeline, judging whether the current locking pipeline is the last pipeline in a construction area or not through an underwater camera, wherein the last pipeline is the last pipeline connected end to end in the construction area;
If not, starting to lock from the end of the last pipeline locking, moving the leveling moving part, stopping moving the leveling moving part when the length between the leveling moving part and the tail end of the pipeline is consistent with the locking stopping distance, stopping outputting stones by the stone throwing ship after the pipeline is locked, separating the first material distributing opening from the chute of the stone throwing ship, and performing the step 9
If the pipeline is locked from the end of the last pipeline locking, the leveling moving part drives the leveling frame to move, the whole pipeline is locked along the moving direction of the leveling moving part, the stone throwing ship stops outputting stones after the pipeline is locked, the first material distributing opening is separated from the chute of the stone throwing ship, and the step 9) is carried out, so that the pipelines in the construction area are conveniently connected.
The step 9) comprises the steps of hoisting a leveling mechanism to a base bed to be leveled at the next position in a construction area by a crane, connecting a first material distributing opening with a chute of a stone throwing ship, driving a lower blanking pipe to be far away from a leveling frame by a leveling telescopic device, installing a leveling limiting piece 147 between a first leveling limiting part 146 and a second leveling limiting part, repeating the steps 3-5), and then performing the step 9.1);
9.1 Hoisting the pipeline to the foundation bed with the leveling completed by the crane;
9.2 Connecting the pipeline to be locked with the locked pipeline;
9.3 Hoisting the leveling mechanism on the foundation bed of the locking pipeline by the crane, wherein the pipeline locking and distributing channels are positioned at two sides of the pipeline;
9.4 And 8) swinging the first material distributing piece to the leveling material inlet channel, locking the material inlet channel to be communicated with the first material distributing opening, and then repeating the step 8), wherein locking of all the pipelines in the construction area is completed.
