Background technology
In July, 1994, Den Norske Stats Oljeselskap a.s. (Statoil Group) have employed a kind of novel foundation pattern---barrel base being different from traditional pile type foundation first on large jacket platform.This basis is the steel Large Diameter Cylindrical Structure of a kind of top seal, bottom opening, and it utilizes negative pressure emptying for the water in bucket, and bucket is inside and outside produces pressure differential, thus makes barrel base injection projected depth.The accreditation that since self-suction formula barrel base occurs, its cost is low, the engineering time is short, lightweight, offshore construction simple installation, the advantage such as reusable obtain world's engineering circles just gradually.
Due to the otherness of geological conditions and the uncertainty of work progress, Blade fence run-off the straight may be caused, the penetration resistance of barrel base can be increased under certain gradient state, barrel base time serious, also may be caused cannot to sink to the problem in precalculated position.
The heavy method for controlling oblique that passes through of current barrel base mainly contains three kinds: (1) Non-follow control, the inclination conditions of artificial judgement Blade fence, and then start-up operation equipment comes leveling basis, and this kind of method control accuracy is low, cannot ensure construction quality; (2) barrel base multi-cavity type method for automatically leveling, carrys out automatic leveling barrel base by the vacuum controlling different cavate, and this kind of method is higher to barrel base structural requirement; (3) there is barrel skirt end that a patented technology for nozzle is installed abroad, control barrel base by the nozzle inject high pressure water and gas controlling different angles and sink the angle of slope in the process of passing through reduce the penetration resistance of bucket skirt.
Summary of the invention
The object of the present invention is to provide a kind of vibrating type Blade fence levelling device.Adopt this device effectively can not only control the leveling of barrel base, and the frictional resistance between barrel base and the soil body can also be weakened, improve depth of penetration.
The technical solution adopted for the present invention to solve the technical problems is:
The present invention includes base plate, bung, vibrating mechanism, two-way angle sensor and solenoid valve control module; Base plate is stamped bung, is positioned at that the base plate of bung is same is circumferentially evenly equipped with multiple vibrating mechanism, the base plate being positioned at multiple vibrating mechanism has two base plate negative pressure mouths, and base plate center is provided with two-way angle sensor; Have malleation mouth, line outlet and bung negative pressure mouth above bung, malleation mouth is connected with the multiple electromagnetic valve input ports in solenoid valve control module respectively, and multiple electromagnetic valve delivery outlet is connected to respective vibrating mechanism pneumatic interface respectively; Bung negative pressure mouth is connected with two base plate negative pressure mouths through solenoid valve control module; The holding wire of two-way angle sensor is connected to programmable logic controller (PLC) by the line outlet on bung together with the control line of electromagnetic valve.
The outer ring of described base plate is same is circumferentially evenly equipped with multiple bolt hole, is connected by the bolt hole of screw with barrel base upper flanges dish outer ring.
Described multiple vibrating mechanism is pneumatic striking mechanism or vibrator, and number is four.
Above described bung, hoisting ring is installed.
Compared with background technology, the invention has the beneficial effects as follows:
(1) adopt vibrating type control method effectively can not only control the attitude of barrel base, and the frictional resistance between barrel base and the soil body can also be weakened, thus improve depth of penetration.
(2) unitary construction is simple, is easy to install, and expense is low, can reuse.
(3) barrel base inclined degree can be detected in real time and control the injection attitude of barrel base.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Fig. 1 ~ Fig. 5, the present invention includes base plate 3, bung 4, vibrating mechanism 10, two-way angle sensor 13 and solenoid valve control module 5; Base plate 3 is stamped bung 4, is positioned at that the base plate 3 of bung 4 is same is circumferentially evenly equipped with multiple vibrating mechanism 10, the base plate 3 being positioned at multiple vibrating mechanism 10 has two base plate negative pressure mouths 12, and base plate center is provided with two-way angle sensor 13; Bung 4 has malleation mouth 6, line outlet 7 and bung negative pressure mouth 8 above, and malleation mouth 6 is connected with multiple electromagnetic valves 16 input port in solenoid valve control module 5 respectively, and multiple electromagnetic valve 16 delivery outlet is connected to respective vibrating mechanism pneumatic interface 14 respectively; Bung negative pressure mouth 8 is connected with two base plate negative pressure mouths 12 through solenoid valve control module 5; The holding wire of two-way angle sensor 13 is connected to programmable logic controller (PLC) by the line outlet 7 on bung through two-way angle sensor interface together with the control line of electromagnetic valve 16.
