Description
Technical Field
The invention relates to a pile driver, in particular to a pneumatic pile driving construction structure with a soil clearing function, and also relates to a pile driver construction method, in particular to a pneumatic pile driving construction structure with a soil clearing function, belonging to the technical field of pile drivers.
Background
The pile driver consists of a pile hammer, a pile frame and accessory equipment, wherein the pile hammer is attached between two parallel vertical guide rods (commonly called a gantry) at the front part of the pile frame and is lifted by a lifting hook, the pile frame is a steel structure tower frame, a winch is arranged at the rear part of the pile frame and is used for lifting the pile and the pile hammer, a guide frame consisting of two guide rods is arranged in front of the pile frame and is used for controlling the pile driving direction so that the pile accurately penetrates into the stratum according to the design direction, the basic technical parameters of the pile driver are the weight of an impact part, the impact kinetic energy and the impact frequency, and the pile hammer can be divided into a drop hammer, a steam hammer, a diesel hammer, a hydraulic hammer and the like according to the power.
The steam hammer pile driver, the pile hammer is made up of hammer head and hammer seat, regard steam or compressed air as the motive force, there are single-acting steam hammer and double-acting steam hammer two kinds, the single-acting steam hammer regards force plunger or air cylinder as the hammer head, the steam drives the hammer head to rise, then let it fall and pile along the guide arm of the hammer seat, the double-acting steam hammer is generally regarded as the hammer head by the weighted force plunger, regard air cylinder as the hammer seat, the steam drives the hammer head to rise, and then drive the hammer head to impact the pile downwards, the speed of reciprocating from top to bottom is fast, the frequency is high, make the pile shake while penetrating the stratum, can reduce the frictional resistance, pile the effectual, the differential steam hammer of the acting force of two-way inequality, its hammer seat weight is light, the effective impact weight can increase relatively, the. The reversing of the steam inlet and outlet rotary valve of the steam hammer can be controlled manually or automatically by a flange operating lever which is arranged at one side of the hammer head and can lift along with the hammer head, and the impact stroke of the steam hammer can be adjusted by the two modes.
The diesel pile driver has main body comprising cylinder and plunger, and operating principle similar to that of single-cylinder two-stroke diesel engine, and has atomized diesel oil sprayed into the combustion chamber of the cylinder to produce strong pressure to drive the hammer head to work, the diesel hammer is divided into guide rod type and cylinder type, the guide rod type diesel hammer is pressed onto the pile cap with the plunger as the hammer seat and lifted along two guide rods with the cylinder as the hammer head, during piling, the pile is first lifted to the pile frame gantry, the diesel hammer is then set on the pile top, the cylinder is lifted with the lifting hook and separated from the lifting hook to let the cylinder fall and sleeve the plunger, the air inside the cylinder is compressed, the cylinder falls continuously until the pressing pin outside the cylinder pushes the rocker of the fuel pump on the hammer seat, the fuel pump sprays oil mist into the cylinder, and the oil mist burns when encountering high temperature gas above the burning point, the blasting force impacts downwards to make the pile fall, pushing upwards to lift the cylinder, and starting the second impacting cycle when the cylinder falls along the guide rod again. The cylinder diesel hammer uses the cylinder as the hammer seat and directly uses the lengthened inner wall of the cylinder for guiding, two guide rods are omitted, and the plunger is a hammer head and can move up and down in the cylinder. When piling, the pile cap at the lower part of the hammer seat is pressed on the pile top, the plunger is lifted by the hook, and then the hook is unhooked to impact downwards, so that air sealed in the cylinder is compressed. The diesel hammer is started by compression ignition diesel oil, so that closed gas in a cylinder must be ensured to reach a certain compression ratio, and sometimes when piling in a soft soil stratum, the hammer can not be ignited and detonated due to small reaction force and insufficient compression amount, and can be started by lifting the hammer head for multiple times by using a lifting hook to unhook and impact. The hammer seat of the diesel hammer is attached with a fuel injection pump, an oil tank, a cooling water tank and a pile cap. The movable gap between the plunger and the cylinder is sealed by an elastic plunger ring.
The hydraulic pile driver is started by a diesel oil belt, can adjust hydraulic pressure according to different soil qualities of a stratum by taking the oil hydraulic pressure as power to achieve proper impact force for piling, is a novel pile driver, is a small and medium-sized hydraulic pile driver, is commonly used for piling of highway guardrails, is used for constructing the highway guardrails, and similar piling equipment is provided with: compared with a diesel pile driver, the energy transfer efficiency of the hydraulic hammer pile driver can reach 70% -95%, the energy transfer efficiency of the diesel hammer pile driver is only 20% -30%, the pile driving control amount of the hydraulic hammer pile driver is accurate, and pile driving operation of different stratums can be achieved.
Wherein the screw pile driver is a pile driving device which drives a drill rod drill bit to form a hole on an underground drill rig through a power head, and the screw pile driver can be divided into two parts: a pile frame and a drilling section.
The hydraulic pile driver, the diesel pile driver and the pneumatic hammer pile driver adopt the hammer body to impact the pile driving rod for driving the pile, although the hydraulic pile driver, the diesel pile driver and the pneumatic pile driver are commonly used for piling, certain defects still exist, the impact of the hammer body is staged, so that the piling efficiency is not high-efficient, the lifting of the centrum is separated from the driving mechanism for driving the pile rod, the occupied space is large, and the hammer body impacts to realize piling, so that the danger is too high, the turned-out soil cannot be cleaned when the middle hydraulic pile driver, the diesel pile driver, the steam hammer pile driver and the spiral pile driver are used for piling, so that the turned-out soil is buried outside the pile driving rod under the action of gravity and vibration force, and the piling efficiency is improved, so that the pneumatic type piling construction structure with the soil clearing function and the construction method are provided for optimizing the problems.
