Abstract
The invention discloses a high-precision compacting and leveling device and method for underwater rubble-mound foundation. The high-precision compacting and leveling device is connected with a ship body via a moving mechanism and comprises an extending steel pipe, a vibrating hammer is connected on the lower portion of the extending steel pipe, a GPS (global positioning system) elevation measuring and controlling system is mounted at the top end of the extending steel pipe, a restraint casing is sleeved outside the extending steel pipe, and a vibrating hammer lifting mechanism controls lifting of the vibrating hammer. The high-precision compacting and leveling device is low in manufacturing cost, can be used in deep water areas of open seas and is lower in cost in shallow water areas as compared with manual leveling, and vibration leveling precision can reach +/- 5cm. The high-precision compacting and leveling method integrates compacting and leveling of the rubble-mound foundation together, realizes integration of the compacting and leveling of the rubble-mound foundation and can remarkably improve compacting and leveling efficiency of the rubble-mound foundation.
Description
Technical field
The invention belongs to subaqueous construction field, particularly the closely knit apparatus for leveling of a kind of underwater works riprap foundation high accuracy and the closely knit flatening method in this field.
Background technology
The closely knit major way of current domestic underwater works riprap foundation has: vibratory compaction, hammer ram, 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, walking evener.
The closely knit mode brief introduction of bedding: it is that to utilize tension weight churning to realize bedding closely knit that hammer rams, and which is long in time limit, expense is high, is difficult to meet fast and requirement that large area is tamped; Short, instant effect of quick-fried rammer duration, and cost is low, and quality also can be guaranteed, but the earthquake sheet that surrounding enviroment are produced is obvious, is therefore subject to the restriction of surrounding enviroment; Vibratory compaction is a kind of new method, and the method duration is short, expense is low, cost is low, and little to ambient influnence, is the trend developing at present.
Base bed flattening mode brief introduction: manually leveling under water: low labour intensity of input cost is large, security risk is large, efficiency of construction is low but manually flatten; Frame type evener: cutting mode falls behind, and blanking position is inaccurate, cannot realize automation and work continuously; Seat bottom type leveling ship: limited by the depth of water; Platform boat form leveling ship: involve great expense; Walking evener: comparatively harsh to execution conditions, accommodation is less.
Summary of the invention
Technical problem to be solved by this invention is just to provide the closely knit apparatus for leveling of a kind of underwater works riprap foundation and closely knit flatening method.
The present invention adopts following technical scheme:
The closely knit apparatus for leveling of a kind of underwater works riprap foundation high accuracy, this device is connected with hull by shift mechanism, this device comprises and stretches out steel pipe, stretch out steel pipe bottom and connect vibrating hammer, the top of stretching out steel pipe is provided with GPS absolute altitude TT&C system, stretch out steel pipe outer cover Constrained sleeve pipe, the lifting of vibrating hammer lifting mechanism control vibrating hammer.
Further, stretch out between steel pipe and confinement sleeve and locate by alignment pin.
The closely knit flatening method of a kind of underwater works riprap foundation high accuracy, right to use requires the closely knit apparatus for leveling described in 2, comprises the steps:
(1) obtain in real time the positional information of vibrating hammer and bedding by GPS absolute altitude TT&C system;
(2) angle of adjusting vibrating hammer and stretching out steel pipe by adjusting confinement sleeve, to ensure the verticality between vibrating hammer and bedding;
(3) extract alignment pin, vibrating hammer is dropped down onto on bedding, open vibrating hammer work;
(4) in the time that GPS absolute altitude TT&C system detects that base bed flattening reaches predetermined elevation, vibrating hammer quits work automatically; Vibrating hammer is carried to predetermined absolute altitude and again plugged after alignment pin, close vibrating hammer hoisting mechanism;
(5) by vibrating hammer hoisting mechanism, vibrating hammer is carried to predetermined absolute altitude, and by vibration leveling mechanism shift mechanism, vibrating hammer is moved to next operating position.
The invention has the beneficial effects as follows:
The closely knit apparatus for leveling of underwater works riprap foundation disclosed in this invention, cost is low, reach ± 5cm of vibration leveling precision, can use in profundal zone, off-lying sea, and the artificial leveling cost of comparing in phytal zone is low.
