Meanwhile, the result as ground evolutionary operation, floating soil 270 may increase.Therefore, the second cap unit 320 raise automatically.It is to say, the floating soil 270 owing to increasing makes to prevent the second cap unit 320 of the muddy device 300 of water It is raised above, prevent the length of the muddy device 300 of water or highly can naturally increase on the whole.In some cases, it is allowed to Capstan winch (not shown) is advanced the speed operated-slowly according to floating soil 270, thus allows capstan winch line (not shown) at leisure Upwards drag and prevent the muddy device 300 of water.

As shown in Fig. 6 f to Fig. 6 i, once excavating bar 230 and being connected to subsea floor with depth capacity, they are same rotate Shi Zaici raises at leisure.Now, rotate owing to excavation bar 230 raises at leisure simultaneously, still carry out agitation operation.

As shown in Fig. 6 j, if completing ground evolutionary operation, then when excavate bar 230 raise while, the first sheet Unit 310 is connected to the retainer 241 of conduit 240, and prevents the muddy device 300 of water from also raising.

It is therefore prevented that the floating soil 270 in the muddy device 300 of water is finally exposed to above subsea floor, but complete Become ground evolutionary operation, so that external impact is not applied to floating soil 270, thus made the ring that floating soil 270 causes Environment pollution is minimum.

Although the illustrative embodiments by reference to the present invention is specifically illustrated in and describes the water according to the present invention Lower soil improvement equipment prevent the muddy device of water, but it will be appreciated by those skilled in the art that without departing substantially from by following right In the case of requiring defined the spirit and scope of the invention, can be to make the various changes in form and details wherein. It accordingly, it is desirable to present embodiment is considered to be exemplary rather than restricted in all respects, is to appended right Require that the scope of the present invention is specified in the reference made rather than description above.
