The pile drilling machine consists of pile hammer, pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guides ( commonly known as gantry ) at the front of the pile frame and lifted by lifting hooks. The pile frame is a steel structure tower with a winch at the back to lift the pile and pile hammer. In front of the pile frame, there are two guiding rods composed of guide rods to control the piling direction, so that the pile can accurately penetrate the formation according to the design orientation. The basic technical parameters of the pile driver are the impact part weight, impact kinetic energy and impact frequency. The power source of the pile hammer can be divided into drop hammer, steam hammer, diesel hammer, hydraulic hammer and so on.
Classify of Pile Drilling Machine
The pile driving machine is mainly divided into screw pile driver and rotary pile driver, mainly including caterpillar rotary drilling rig, wheel rotary drilling rig, caterpillar pile driver, wheel pile driver, walking pile driver, screw pile driver, solar photovoltaic power station special pile driver, 360-degree rotary pile driver and other pile machinery.
Features of Pile Drilling Machine
The vehicle can be used for both power generation and external power supply. It is suitable for piling works such as building foundation construction, road foundation reinforcement, railway power facilities, wind power plants, solar photovoltaic power plants and soft soil treatment reinforcement, etc.
Screw Pile Driver
The screw pile driver is a kind of pile driving equipment which drives the drill pipe bit through the power head to make holes in the underground drilling machine. The screw pile driver can be divided into two parts: the pile frame and the drilling part.
Working Principle of The Screw Pile Driver
The pile frame of the screw pile driver machine is mainly composed of top pulley group, vertical column, diagonal strut, chassis, traveling mechanism, rotary mechanism, hoist mechanism, control room, hydraulic system and electrical system. The column is folded, adopting a box-shaped structure and flange connection. Round and square slides are provided on both sides of the column as the guide head and anti-twist for the power head and the up and down movement of the drill pipe. The box-shaped collapsible column equipped with this kind of drilling rig can take off and land by means of hydraulic cylinder, which is convenient and quick, and does not need to be disassembled during transportation. The lower part of the column is hinged with the upper plate, the middle and rear of the column is hinged with the oblique brace, and the top of the column has a block of pulleys, which is used to complete the take-off and landing of the power head, the steel cage and the grouting conduit, etc. The power head can slide up and down along the slide and can be removed when carrying.
Rotary Pile Driver
The rotary drilling pipe driver with the characteristics of fast hole formation, less pollution and strong maneuverability is a comprehensive drilling machine, which can use a variety of bottom layers, has the characteristics of fast hole formation, less pollution and strong maneuverability. The short auger bit is used for dry excavation work, or the rotary digging bit can also be used for wet excavation in the case of mud retaining wall. The rotary digging pile driver can perform the digging operation after drilling the hard ground with the hammer. If the head drill is enlarged, the hole can be reamed at the bottom of the hole. The rotary excavation pile driver adopts multi-layer telescopic drill pipe, which has less drilling assistance time and quick hole formation. It is suitable for various formations.with the features of low labor intensity, no need for mud circulation slag discharge, cost saving and less pollution, the machine is especially suitable for basic construction of urban construction.
The Main Performance Characteristics of Rotary Pile Driver
1.High mobility and quick transfer.
2.The drilling tools are various in variety and light, which can be quickly loaded and unloaded.
3.Adapt to a variety of formations and the speed is fast, about 80% faster than the impact drill.
4.It is less polluting to the environment and does not require recycling.
5.Multiple types of piles can be corresponding.
Compared with the rotary drilling rig, the rotary drilling rig has less mud and less pollution to the environment. At the same time, it can reduce the transportation cost of the mud, and has good economic and environmental benefits. In the construction of rotary drilling rig, there are few quality problems, such as reaming, shrinkage, collapse and so on, which have good social benefits. Compared with the percussion drilling rig, the rotary drilling rig saves a lot of time and does not produce a lot of noise, so it has good social and economic benefits.
Guardrail Pile Driver
The guardrail pile driving machine is a kind of highway guardrail steel pipe pressing equipment, which adopts diesel power, full hydraulic mechanical transmission. It has the characteristics of light driving, high piling precision, durability, energy saving and environmental protection. It is especially suitable for highway guardrail installation, maintenance and field repair construction for repairs.
Characteristics of Guardrail Pile Driver
