At present at home to the reinforcing on similar basis, adopt deep mixing method or compaction grouting method mostly, but these methods of evidence also are not suitable for underpin under the deep muck foundation condition in coastal area, and possible disturbance power supply unit basis is stable, the particularly ground stabilization that disperses for this kind equipment basis of transformer station, its cost is very high, and consolidation effect is not obvious.
In a single day high voltage substation puts into effect, generally do not allow to have a power failure, and the difficult point of this transformer station's enforcement underpin is:
(1) the 220kV transformer station charged place construction operation that is in operation, safety requirements is high, and the strengthening construction operation height restriction under charging equipment is at 2.2m;
(2) various existing construction machineries are subjected to the safe construction distance limit, all can not enter site operation;
(3) can not the former basis of disturbance when underpin;
(4) because equipment and basis from heavy and light, can not utilize the counter-force that is reinforced the basis when reinforcing.
Summary of the invention
The technical problem to be solved in the present invention is at transformer station's mud or soft foundation Equipment Foundations settlement issues, under the requirement that limits safe altitude 2.2m, do not have a power failure, has proposed the reliable miniature piling machine of a kind of construction safety.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of miniature piling machine, comprise base, frame, hoist engine and pile monkey, the wire rope of hoist engine joins by the leading block and the pile monkey of upper rack, be characterized in: the high 1.50～2.20m of frame, frame front is provided with the pile monkey guiding mechanism, described pile monkey guiding mechanism comprises the ground top guide bar that is arranged on base top and is arranged on the ground lower guide rod of base bottom, be provided with a link at the top of pile monkey, what cooperate with link is provided with hook, hook is provided with a long joystick, and the middle part of the end of hoist engine wire rope and described hook coupler body is hinged.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, described ground top guide bar and ground lower guide rod are set to one, be arranged three in parallel, described pile monkey is located between three guide rods, vertically is provided with the three road slideways that cooperate with guide rod on the pile monkey accordingly.
The present invention compared with prior art, at transformer station's sea alluvial plain based device foundation settlement problem, at restriction safe altitude 2.2m, do not have a power failure the electricity requirement under, developed miniature piling machine, carried out the reinforcing experimental study, explored and under complicated soft foundation condition, adopted miniature steel pipe pile reinforced power equipment basis, to stop the effective ways of its sedimentation, broken through the forbidden zone of carrying out underpin inconvenience piling in this special construction environment of transformer station that is in operation, the stake top application that adopts in the test adds the prestressed reinforcement new technology, have remarkable effect to reducing foundation settlement, successfully solved this technical barrier.Prove that by experimental study this technology is used the pile foundation underpinning principle, adopt and squeeze into the shaped steel pile tube that declines, penetrate soft layer, can effectively stop foundation settlement.
It is simple to operate, at first prefabricated stub lifting is put in place, and hoist engine is sling pile monkey, pulls joystick downwards, and hook is thrown off with link, and then the pile monkey freely falling body is downward, precast piling is thrown into underground.Construction period does not have a power failure, and has avoided the loss of operating a switch and having a power failure and giving power supply department and cause with electric unit.This pile driving equipment volume is small and exquisite, and the space that a very important person can stand is the energy piling construction just, is subjected to the restriction of space environment hardly, and the foundation settlement reinforcement and rectification for the equipment of industrial product has good compliance equally.Can often occur as local foundation settlement during the civic building building reinforce is transformed at present, the indoor Liang Huanzhu that takes out transforms, service load strengthens various technical barriers such as needing to increase the basis, the remarkable advantages of the present invention is, its service condition is loose, the less space environment of reinforced structure that is subjected to influences, and has brilliant market developing prospect.
