Bury the serious problems such as steel reinforcement cage.
Summary of the invention
The shortcomings that the utility model is overcome now in the art provides a kind of suitable for deep hole large diameter hole pile cages
The operating platform of construction, it is intended to improve original drilled pile reinforcing cage in aperture and connect the construction technology of decentralization section by section, make in advance
Steel reinforcement cage, steel reinforcement cage can splice in parallel in fabrication hole while drilling, may be implemented by the utility model: first is that steel
Muscle cage assembly no longer need to until drilling terminate borehole cleaning after could splice, can with drill parallel operations, accelerate construct into
Degree, ensure that the duration;Two are the reduction of the connector quantity of aperture connection after pore-forming, shorten the construction time, high degree subtracts
The small risk of collapse hole, overcomes the sediment thickness of the bottom hole problem too long and exceeded because of the steel reinforcement cage construction time, ensure that into
Quality of pile.
The technical solution of the utility model is: a kind of operating platform suitable for the construction of deep hole large diameter hole pile cages,
The round card slot type that the fan-shaped platform of steel pile casting including fabrication hole and the piecemeal by steel pile casting surrounding is arranged in forms operates flat
Platform, the sector platform are that two blocks of angle steel weld the skeleton to be formed by junction steel plate, are expired between the skeleton with crude steel silk screen
Paving;Card slot is formed between two blocks of angle steel, the card slot is stuck on steel pile casting.
Compared with prior art, the utility model has the advantages that: be greatly shortened steel reinforcement cage decentralization the time required to, and
Good condition is created for next step secondary pile hole cleaning, accelerates integrated engineering construction speed, saves labor for subsequent process
The investment of the costs such as power, machinery, material.
Traditional construction technology is to weld section by section in aperture, but the characteristics of deep hole large diameter drill hole pile is that steel reinforcement cage is long
Degree length, the quantity of merogenesis is more, and bar diameter is big to be needed using sleeve connection, and installation difficulty is big, cannot can be made as welding with multiplexing
Surface construction, sleeve connection must obtain incremental, each sleeve can only be bit by bit tight inward, time-consuming especially more, at this
Being suspended in the boring mud among mud in the process can slowly precipitate, and the time is longer, and the boring mud of precipitating is more, and the difficulty of secondary pile hole cleaning is just
It is bigger, and the risk that steel reinforcement cage is buried is higher.
The utility model mainly solves that steel reinforcement cage aperture jointing quantity is more, and consuming time is long, bottom hole sediment thickness
The problems such as being difficult to control, and the construction of steel reinforcement cage can be started while drilling, the time of each circulation is shortened, very greatly
Construction speed is accelerated in degree, is very suitable to duration tighter project.
