Technical Field

The utility model relates to a pile foundation construction equipment technical field especially relates to a flexible long lead hole pile driver device that bridge crane used.

Background

The construction of the upper structural member of the existing highway, railway, pipeline and the like viaduct increasingly adopts a method of prefabricating in factories and then transporting to a site for assembly so as to accelerate the construction progress. The bridge girder erection machine is equipment for driving on a bridge track and placing a prefabricated beam piece on a prefabricated bridge pier, and the method requires that a lower pile foundation is constructed in advance, and the pile foundation needs an independent construction scheme to be constructed in advance. If the engineering geological conditions are complex or in rivers, seas and lakes, the pile foundation construction difficulty is large, the engineering progress is slow, and the construction cost is high by adopting additional equipment such as a piling ship, a temporary trestle and the like.

In order to solve these problems, the applicant patent of the present invention is a utility model patent with CN201921824290.6, which discloses a self-supporting pile driver, the self-supporting pile driver comprises a bridge erecting mechanism, a pile driving mechanism, a folding mechanism, the pile driving mechanism mounted on the bridge erecting mechanism through the folding mechanism comprises a column tower, an amplitude guide rail, a rotary support, an amplitude cylinder fixing seat, a movable bolt, a lifting winch, a lifting steel wire rope, a lifting pulley block, a pile driving hammer and a front guide rail, and the pile driving mechanism can only hammer a common precast pile on a soft soil layer foundation. However, in practical engineering, since the engineering has a high requirement on settlement control, a soil layer below a soft soil layer is required to be used as a bearing layer, so that the precast tubular pile generally needs to penetrate through a soft soil layer and a hard soil layer above the soft soil layer, generally a sandy soil layer, and when the thickness of the sandy soil layer is large (generally more than 10m), the pile sinking of the large-diameter tubular pile is very difficult no matter the hammering and static pressure pile sinking process is adopted due to the soil plug effect, particularly for the large-diameter tubular pile. For projects which generally need to cross thicker sandy soil layers (generally more than 10m) and have longer pile lengths (generally more than 40m), pile sinking by adopting a hammering process is very difficult.

Therefore, it is required to develop a pile driving pilot device for a bridge erecting machine, which is capable of performing a self-supporting pile driving in the air and performing a pile sinking operation in a thick hard soil layer, so as to increase a construction speed.
