Amphibious pile driver

Abstract

The invention relates to the technical field of a pile driver and discloses an amphibious pile driver. The amphibious pile driver comprises a base, a working device arranged on the base, an elevated buoyancy tank. The base comprises an internal weight, a powerplant, a gearing device and a control device. The amphibious pile driver also comprises two sets of crawler units respectively arranged on both sides of the base bottom, with each comprising two parallel caterpillar belt mechanisms connected by a binding mechanism; and stretchable outriggers to adjust the height of the elevated buoyancy tank for different working depth. The stretchable outriggers are connected to the binding mechanism and the elevated buoyancy tank and transfer the power to the gearing device to drive the crawler units. This amphibious pile driver of invention can carry out the piling work in the offshore area safe and fast.

Description

technical field [0001] The invention relates to the technical field of piling equipment, in particular to an amphibious pile driver. Background technique [0002] With the increasingly severe energy situation, the wind power industry has maintained rapid development in recent years, and the wind resources in coastal tidal flats have been effectively utilized, but it is still in the initial development stage. One of the difficulties is the lack of maneuverability in the construction of wind farms in coastal tidal flats. There are two types of existing pile drivers: land pile drivers and offshore pile drivers. [0003] Among them, for land-based piling equipment, such as crawler pile drivers and static pile drivers, although they have good maneuverability and simple construction, they require high ground bearing capacity (MPa level) when driving and piling. When the tidal flat area is at low tide, construction cannot be done directly on the tidal flat (the bearing capacity of...

Problems solved by technology

[0003] Among them, for land-based piling equipment, such as crawler pile drivers and static pile drivers, although they have good maneuverability and simple construction, they require high ground bearing capacity (MPa level) when driving and piling. When the tidal flat area is at low tide, construction cannot be done directly on the tidal flat (the ground bearing capacity of the tidal flat is less than 50KPa), and the equipment is prone to subsidence and overturning; It has strong maneuverability and can realize fast transportation at sea, but it has a large tonnage and a deep draft, and it cannot be stranded, and it is not suitable for the intertidal zone

In addition, coastal tidal flats have a vast area, complex geology, low bearing capacity and uneven distribution, shallow water level, two tides a day, and unpredictable sea weather. The above two kinds of lifting and piling equipment cannot be used well, so piling construction is carried out. It is a major problem in the construction work in coastal tidal flat areas
