The adjustment cylinder 392 adjusts the installation casing 391 according to the variable amount of altitude measured by the height measuring device 393 to correct the installation height.

That is, when the altitude falls from the height measuring device 393, it is possible to determine that the aggregate laying height of the seabed ground is lowered, thereby driving the adjustment cylinder 392 with the lowered altitude to raise the adjustment casing 391 to correct the laying height. At this time, the accuracy can be compensated in units of 5mm, and for this purpose, the adjustment cylinder 392 is provided with a scale capable of precise length measurement.

In addition, the height sensing sensor can measure the submarine ground at the position to be installed during installation, and if the difference between the installation height is generated, the driving speed of the first driving member 340 and the second driving member 350 can be controlled. 510 is provided.

Therefore, if the subsea ground at the position to be installed has a large difference between the installation height, at that position, the speed of the first driving member 340 and the second driving member 350 is decelerated in proportion to a variable amount to increase the amount of aggregate installed. If the difference is small, the speed of the first driving member 340 and the second driving member 350 is increased to reduce the amount of aggregates to be installed.

In addition, the tremi tube 360 is provided with a first aggregate sensor 363 and the second aggregate sensor 364 for detecting the amount of aggregate injected therein. Here, the operation of the aggregate transport unit 400 is determined according to the signal detected by the first aggregate sensor 363 and the second sensor.

That is, when the aggregate is detected by the second aggregate detection sensor 364 by installing the first aggregate detection sensor 363 and the second aggregate detection sensor 364 on the upper portion of the aggregate transport unit 400 When the aggregate supply is stopped and aggregate is not detected by the first aggregate sensor 364, the aggregate supply of the aggregate transfer unit 400 is resumed.

And a hopper 440 for supplying aggregates to the first conveyor 410 by a predetermined amount and a transfer conveyor 430 for supplying the aggregates supplied from the hopper 440 to the first conveyor 410.

Here, the aggregate should be injected into the tremic tube 360 which is moved along the first frame 310 and the second frame 320 so that the dropping position of the first conveyor 410 and the second conveyor 420 may be moved. Prepared. That is, by providing a moving means not shown in the conveyor itself, it is possible to adjust the first conveyor 410 and the second conveyor 420 in the longitudinal direction and the width direction according to the position of the tremi tube (360).

However, in the present invention, each of the first conveyor 410 and the second conveyor 420 is provided with a first drop position variable member 411 and a second drop position variable member 421 having a predetermined inclination. The first dropping position variable member 411 and the second dropping position variable member 421 are moved along the first conveyor 410 and the second conveyor 420.

That is, the first dropping position variable member 411 is positioned below the belt of the first conveyor 410 and moves along the conveyor to form a slanting path of the belt to be dropped onto the second conveyor 420.

In addition, the second drop position variable member 421 is positioned under the belt of the second conveyor 420 and moves along the conveyor to form an inclined path of the belt so as to be dropped onto the tremi tube 360 of the installation device 300. do.
