Description
Technical field
The invention belongs to underwater construction field, a kind of underwater works rubble-mound foundation more particularly in the field is in high precision
Closely knit apparatus for leveling and closely knit flatening method.
Background technology
Country's underwater works closely knit major way of rubble-mound foundation has at present：Vibratory compaction, hammer are rammed, three kinds of modes of quick-fried rammer；
Underwater bed leveling major way has：Artificial leveling, frame-type evener, seat bottom type leveling ship, platform boat form leveling ship, stride
Formula evener.
The closely knit mode brief introduction of bedding：Hammer rammer is to realize that bedding is closely knit using tension weight churning, and which is long in time limit, expense
Height, it is difficult to meet the requirement of quick and large area compacting；Quick-fried rammer short time limit, instant effect, and low cost, quality can also be protected
Card, but the earthquake sheet produced to surrounding enviroment is substantially, therefore restricted by surrounding enviroment；Vibratory compaction is a kind of new side
Method, the method short time limit, expense are low, low cost, and effect on environment is small, are the trend of current development.
Base bed flattening mode brief introduction：Artificial leveling under water：Manually but low labour intensity of input cost of leveling is big,
Security risk is big, low construction efficiency；Frame-type evener：Cutting mode falls behind, and lower discharge position is inaccurate, it is impossible to realize automation
Work continuously；Seat bottom type leveling ship：Limited by the depth of water；Platform boat form leveling ship：Involve great expense；Walking evener：To construction
Condition is more harsh, and accommodation is smaller.
The content of the invention
The technical problems to be solved by the invention be just to provide a kind of closely knit apparatus for leveling of underwater works rubble-mound foundation and
Closely knit flatening method.
The present invention is adopted the following technical scheme that：
A kind of closely knit apparatus for leveling of underwater works rubble-mound foundation high accuracy, the device is connected by shift mechanism with hull
Connect, the device includes stretching out steel pipe, stretch out steel pipe bottom connection vibration hammer, the top for stretching out steel pipe is provided with GPS absolute altitude observing and controlling
System, stretches out steel pipe outer cover Constrained sleeve pipe, the lifting of vibration hammer lifting mechanism control vibration hammer.
Further, stretch out between steel pipe and confinement sleeve by positioning finger setting.
A kind of closely knit flatening method of underwater works rubble-mound foundation high accuracy, uses above-mentioned underwater works rubble-mound foundation
Closely knit apparatus for leveling, comprises the following steps in high precision：
(1) positional information of vibration hammer and bedding is obtained in real time by GPS absolute altitudes TT＆C system；
(2) angle that vibration hammer stretches out steel pipe is adjusted by adjusting confinement sleeve, to ensure vibration hammer and base
Perpendicularity between bed；
(3) alignment pin is extracted, vibration hammer is dropped down onto on bedding, open vibration hammer work；
(4) when GPS absolute altitude TT＆C systems detect base bed flattening reaches predetermined elevation, vibration hammer is automatically stopped work
Make；After carrying vibration hammer to predetermined absolute altitude and plug alignment pin again, vibration hammer hoisting mechanism is closed；
(5) vibration hammer is carried to predetermined absolute altitude by vibration hammer hoisting mechanism, and by vibration leveling mechanism shift mechanism
Vibration hammer is moved into subsequent work position.
The beneficial effects of the invention are as follows：
The closely knit apparatus for leveling of underwater works rubble-mound foundation disclosed in this invention, low cost, vibration leveling precision reach
± 5cm, can be used in off-lying sea profundal zone, in phytal zone compared to relatively artificial leveling low cost.
The closely knit flatening method of underwater works rubble-mound foundation disclosed in this invention, be with leveling function collection by bedding is closely knit
Integrally, realize underwater works rubble-mound foundation it is closely knit, leveling operation unite two into one, be remarkably improved rubble-mound foundation it is closely knit, leveling
Efficiency.
