Adjustment adjustment pontoon sinks can also make pontoon sink with immersible pump toward water filling in pontoon water tank, and pontoon is fixed, then Water in Water Tanks discharge is mitigated into pontoon with pump carrying after sinking with steel-pipe pile, pontoon is produced buoyancy and is transferred to steel-pipe pile.
When steel-pipe pile is transferred to using shake hammer vibrations steel-pipe pile, shake loose steel-pipe pile surrounding soil, beneficial to group stake.
Embodiment 2
Steel-pipe pile pile pulling constructing device in low spatial water, including pontoon 1, shake hammer 3, frame 5 and pulley 9, pontoon 1 are made up of two hulls, have link 4 between two hulls.Each solid volume field machine 2 of each pontoon, frame 5 is installed on two pontoons 1, and pulley 9 is installed on the centre of the crossbeam 6 of frame 5, and the steel wire rope of hoist engine 2 is by pulley joint steel pipe stake 7.Pontoon 1 connects the steel-pipe pile 7 of group pile driving construction by the steel wire rope of hoist engine 7, and the contact vibrations steel-pipe piles 7 of shake hammer 3 shake loose the surrounding soil of steel-pipe pile 7, beneficial to group stake.
Steel-pipe pile pile pulling Specific construction device and construction technology describe in detail as follows in low spatial water:
(1) pile pulling device:
1st, pontoon hull structure:
1) design load:
Pontoon designs bearing load includes pile pulling power, pontoon deadweight, two hoist engines and equipment self-weight etc. pile pulling frame, while considering personnel and sundry miscellaneaus object load sum.Steel-pipe pile uplift force is designed as 40 tons, and pontoon deadweight is 27 tons, and from weighing about 6 tons, pile pulling frame is 3 tons to two hoist engines, and operating personnel and miscellaneous load are default 3 tons, adds up to load to be 79 tons.
2) structure design:
Pontoon designs two, each length 8 meters, wide 4.5 meters, high 2-2.5 meters, two 1 meter of pontoon arrangement intervals, and two pontoons are connected as into entirety using link in pontoon front end.To meet the requirement of pontoon its own rigidity in use, pontoon inner frame is using No. 20 channel-section steels of Two bors d's oeuveres are as major architectural stressed member and are equipped with No. 10 channel-section steels, 10 bugle steel as auxiliary stressed member.
3) thin portion pattern handling:
Pontoon maximum displacement is 174 cubic metres, can provide buoyancy for 69 tons/meter.Pontoon and plant equipment deadweight are 39 tons before non-pile pulling, pontoon now 56 centimetres of submerged, to ensure that stabilization of the pontoon in water is also needed to injecting a certain amount of water in pontoon, pontoon center of gravity is reduced with this, therefore in advance to about 20 cubes of water filling in pontoon, pontoon submerged minimum-depth is made to be 80 centimetres.
Because the asymmetry of pontoon this body structure and front end add the influence after link, both sides are unsymmetric structure, two parts weight difference 3.4t with respect to geometric center lines before and after pontoon.The balance overall to ensure pontoon, counterweight water tank is added in pontoon afterbody.Need to can judge water injection rate according to the equilibrium depth of pontoon submerged during water flood operations to the water filling in water tank to make pontoon both sides keep balancing.
2nd, shake hammer:
The vibration hammer of another key equipment is designed to flat to reduce its pile pulling space for being utilized in being constructed as pile pulling.Highly it is 78 centimetres, it is long 205 centimetres, it is wide 148 centimetres, it is possible to provide 90 tons of the power that impulses, 45 tons of pile pulling power.Draw-gear of three groups of running blocks of wheel as shake hammer is set in shake hammer both sides, pulley lower section sets damping spring to reduce loss of the shaking force by influence and impulse power of the wire rope transfers to pontoon.Shake hammer bottom sets clip pile device, and clip pile tool is designed as the adjustable pile pulling needs for meeting different tube diameters pipe in the range of 600mm-800mm.Vibration hammer is connected through two groups of movable and fixed pulleys and horizontal steel I-beam by steel wire rope with hoist engine.
3rd, fixed pulley:
The fixed pulley for playing steering-effecting uses two groups of special 32 tons of assembly pulleys of three-wheel.400 millimeters of height of pulley, 364 millimeters of length, 355 millimeters of width, 280 millimeters of main wheel wheel footpath.Pulley is fixed and is connected with crossbeam I-steel using welding manner, by four piece of 20 steel plate of millimeters thick and I-steel bottom surface edge of a wing plate weld on pulley.The two pairs of assembly pulleys be arranged symmetrically with crossbeam both sides, it is corresponding with the running block position on shake hammer.
4th, pile pulling frame:
Pile pulling sets up meter using φ 340mm pipes as support column, upper erection vertical, horizontal Two bors d's oeuveres I360 steel I-beams, 300 centimetres of pipe height, and I-shaped steel longitudinal beam is long 600 centimetres, crossbeam is long 300 centimetres.The pipes of φ 340 are connected with pontoon panel and longeron using flange.Local strengthening treatment is done in pipe relevant position on I-steel.Hanger is set on crossbeam being connected with fixed pulley group and be provided with auxiliary hanger is used to be connected with pulley wire rope, because fixed pulley stress is larger so relevant position should also do local strengthening on crossbeam, aids in hanger to be arranged on beside pulley.
5th, hoist engine:
Two 5 tons of slow-speed hoist engines are set to be laid on pontoon top board.The steel wire rope of hoist engine initially passes through fixed pulley and is then passed through movable pulley and winds last by steel wire rope in this way being connected with the auxiliary hanger of setting on I-steel by transfer.
6th, immersible pump:
Setting 2, immersible pump is used to adjust pontoon underwater penetration.Immersible pump is 4 cun of immersible pumps, and the pump displacement is 100 cubes ms/h.Immersible pump is arranged at pontoon rear end.
7th, link between pontoon:
Link, into girder system, is connected, three groups of truss totally between shaped steel using No. 20 channel-section steels and 10 bugle steel spellings using welding manner, is attached using horizon bar between truss, is finally integrated link with φ 22mm bolt connections with two pontoons.
(2) construction technology:
1st, preparation before pile pulling:
1) utilizes two immersible pumps while, making pontoon keep anterior-posterior balance to the cm of water filling 40 in the water tank of two pontoon front ends setting highly.
2) makes pontoon sinking certain depth to water filling in pontoon again, depending on the safe altitude apart from 10-20 centimetres of the pontoon submerged depth according to pile pulling frame apex distance steel box-girder bottom on pontoon.Maximum submergence depth is 150 centimetres, and minimum submergence depth is 80 centimetres.
3) steel-pipe pile is cut to more than the water surface 20 centimeters in advance before pile pullings.
4) puts pontoon under bridge bottom, is located in pre- pile pulling position (pontoon sets link side towards in bridge).
2nd, pile pulling construction is carried out:
1) hammer will be shaken using hoist engine and will hang on steel-pipe pile top, and opening oil pump makes shake hammer clamping steel-pipe pile tube wall into shape.
2) start shake hammer to be shaken, hit after brisance makes steel-pipe pile sinking 10-20 cms using the high frequency of shake hammer, start elevator machine travel and pile pulling power is provided.
3) with the raising of hoist engine tractive force, pontoon will will substantially stop to sinking because of stress after pontoon sinks 60 cms, and the buoyancy that now pontoon is supplied to is possible to meet the requirement of 40 tons of uplift force needed for pile pulling.
4) stop traction after steel-pipe pile is pulled out allows length to support height, loosen shake hammer.Now pontoon is floated up because stress reduces, and pontoon is may move after shake hammer lifting goes out pipe height.
5) driving to same row next pre- pile pulling position pontoon carries out pile pulling while turnover cargo ship is sailed into, with cutting equipment on turnover cargo ship, in steel-pipe pile, 20 centimetres of position gas cuttings cut off pipe at surface of water, and the pipe after being cut off with Unwinding chains is transported to turnover transport Ship Transportation disembarkation.
