5, hoist engine:
Two 5 tons of slow-speed hoist engines are set to be laid on the pontoon top board.The wire rope of hoist engine passes fixed pulley earlier by transfer and passes movable pulley again and twine in this way at last one of wire rope is connected with the auxiliary hanger that is provided with on the i iron.
6, submersible pump:
2 on submersible pump is set is used to regulate the pontoon underwater penetration.Submersible pump is 4 cun submersible pumps, and this pump displacement is 100 cubic metres/hour.Submersible pump is arranged at the pontoon rear end.
7, link between the pontoon:
Link adopts No. 20 channel-section steels to become the truss system with 10 bugle steel spellings, adopts welding manner to link to each other between the shaped steel, and totally three groups of truss adopt horizon bar to connect between truss, at last link and two pontoons are connected as one with φ 22mm bolt.
(2) construction technology:
1, preparation before the pile pulling:
1). utilize two submersible pumps about 40 centimetres height of water filling in the water tank that two pontoon front ends are provided with simultaneously, make pontoon keep anterior-posterior balance.
2). water filling makes pontoon sinking certain depth in pontoon again, the pontoon submerged degree of depth at the bottom of according to pile pulling frame apex distance steel case beam on the pontoon the safe altitude apart from 10-20 centimetre and decide.Maximum submergence depth is 150 centimetres, and minimum submergence depth is 80 centimetres.
3). before the pile pulling steel pipe pile is cut to 20 centimeters more than the water surface in advance.
4). at the bottom of putting pontoon under bridge, be located in pre-pile pulling position (pontoon is established link one side in bridge).
2, carry out the pile pulling construction:
1) utilize hoist engine will shake hammer and hang on the steel pipe pile top, and the unlatching oil pump makes the shake hammer clamp the steel pipe pile tube wall.
2) start the shake hammer and shake, after utilizing the high frequency of shake hammer to hit brisance to make about 10-20 centimetre of steel pipe pile sinking, starting the hoist engine traction provides pile pulling power.
3) along with the raising of hoist engine tractive force, pontoon because of stressed will be to sinking, will stop substantially after about 60 centimetres when pontoon sinks, the buoyancy that this moment, pontoon offered can satisfy the requirement of 40 tons of the required uplift forces of pile pulling.
4) stop traction when steel pipe pile is pulled out after support height allows length, loosen the shake hammer.This moment, pontoon upwards floated because of stressed reducing, and was removable pontoon after the lifting of shake hammer goes out the pipe height.
5) pontoon is left to carry out pile pulling with the next pre-pile pulling position of row and will have enough to meet the need cargo ship simultaneously and sail into, with gas cutting pipe is excised 20 centimetres of positions at surface of water at steel pipe pile with cutting equipment on the turnover cargo ship, the pipe after will cutting off with the Unwinding chain is transported to turnover cargo ship transportation disembarkation.
