Linked guide rod diesel oil pile driving hammer and pile driving method thereof

Abstract

The invention discloses a linked guide rod diesel oil pile driving hammer and a pile driving method thereof. The linked guide rod diesel oil pile driving hammer comprises an extensible working mechanism, a lifting mechanism and a connecting mechanism; the working mechanism determines the number of connected guide rod type diesel oil pile driving hammers according to the diameter of a pile to be driven; the lifting mechanism comprises a winch, a steel wire rope, a pulley bracket with a single pulley, and a plurality of pulley brackets with four pulleys; the connecting mechanism is adaptive to the structure of the pile to be driven, and comprises a linked support frame, a cylinder hammer fixed connecting plate and a piston fixed connecting plate; synchronous lifting of cylinder hammers of all guide rod type diesel oil hammers is controlled, and superposed huge impact for driving the pile is generated, so that the problem that the conventional pile driving hammer cannot be used for driving a steel tube pile, a steel projecting canister, a steel sleeve box and a concrete prefabricated tubular pile and the problem of construction of large circular or square piles or piles of other shapes are solved; and the components of the pile driving hammer are detachably assembled, so the pile driving hammer has the characteristic of flexibility.

Description

technical field [0001] The invention relates to a diesel piling hammer, in particular to a linked-type guide rod diesel piling hammer and a piling method thereof. Background technique [0002] Single guide rod diesel piling hammer has been widely used as a foundation piling equipment in the construction of bridges, embankments, house construction and general construction projects. However, in some large-scale engineering projects such as the construction of cross-sea bridges, due to the large diameter and heavy weight of steel piles, a single guide rod type diesel piling hammer cannot work. The largest existing diesel piling hammer can only produce 6000~ The disadvantages of the impact force of 10000KN are: firstly, piles with large diameters cannot be driven; secondly, piles with larger tonnages cannot be moved at all. [0003] Other piling hammer equipment such as linked hydraulic vibratory hammer has certain feasibility in the construction of large steel piles. The linke...

Problems solved by technology

However, in some large-scale engineering projects such as the construction of cross-sea bridges, due to the large diameter and heavy weight of steel piles, a single guide rod type diesel piling hammer cannot work. The largest existing diesel piling hammer can only produce 6000~ The disadvantages of the impact force of 10000KN are: firstly, piles with large diameter cannot be driven; secondly, piles with larger tonnage cannot be moved at all.

[0003] Other piling hammer equipment such as linked hydraulic vibratory hammer has certain feasibility in the construction of large steel piles. The linked hydraulic vibratory hammer produced by American APE Company can produce a maximum shock force of 48000KN, but it still cannot meet the construction requirements of some piles. , such as when constructing a steel pile with a diameter of 29 meters and a weight of 700 tons, the impact force is insufficient, the efficiency is low, and the cost is high
