Description
Technical field
The utility model relates to pile driving equipment technical field, is specifically related to a kind of pile driver.
Background technology
Pile driver is made up of pile monkey, pile frame and ancillary service etc.Pile monkey is attached to the parallel vertical guide rod in two, pile frame front portion, is commonly called as between gantry, hangs liter with lifting hook.Pile frame is a steelwork tower truss, is provided with hoist engine at its rear portion, in order to lift by crane stake and pile monkey.The leading truck be made up of two guide rods before pile frame, in order to control piling direction, makes stake according to design injection stratum exactly, orientation.Pile monkey by motion power resources can be divided into drop hammer, steam hammer, diesel hammer, hydraulic hammer etc.Pile driver utilizes impact force by the piling machinery on stake injection stratum.Pylon and leading truck can together with deflection, in order to batter piling.Pile frame can rotate, and also can divide a word with a hyphen at the end of a line.
Pile driver is divided into following a few class: drop hammer pile monkey is a steel pouring weight, by hoist engine hook, drives piles after unhook along leading truck free-falling.The pile monkey of ram steam pile driver is made up of tup and hammer seat, with steam or compressed air for power, has single-acting steam hammer and double acting steam hammer two kinds.The main body of diesel hammer pile driver is also made up of cylinder and plunger, and its operating principle is similar with single-cylinder double stroke diesel engine, utilizes the atomized diesel fuel spraying into combusted cylinder indoor to drive tup to work by firing produced crunch after high pressure-temperature.Hydraulic hammer pile driver is diesel oil tape starting, take oil liquid pressure as power, can by stratum soil property difference adjustment hydraulic pressure, and driving piles to reach suitable impact force, is a kind of novel piling machine.Screw pile driver is a kind of by the pile driving equipment of unit head drive rod bit to drifter drill for underground pore-forming.Screw pile driver can be divided into two parts: pile frame and creep into part.
In sum, no matter how type changes traditional pile driver, is all to utilize piling power source to be driven underground by pile body, and pile body is remained into the plant equipment of underground.This piling mode needs the more resource of waste and equipment.When piling work, be subject to the restriction of pile body diameter, after an operation that falls completes, pile body stays underground, and pile body diameter is unchanged, and stress point is all made up of pile body, and pile body accepts uneven from top to bottom, affects building of superstructure.Pile body stays the reservation member of underground as necessity, can not have enough to meet the need Reusability, waste resource.Further, easily there is Defect Piles in traditional pile driver in use, and traditional processing method has the multiple stake of expansion cushion cap, original position, pile extension, the sinking shaft of the stake heart, piling, boring to strengthen, change construction method or Amending design scheme.Some great pile accident difficult treatment, costly.Once there is Defect Piles, take above-mentioned examination & verification one method all can cause added cost, increase expenditure, and the defect problem after global design may be caused to change.Therefore, adopt traditional pile driver to reserve inconvenience that the mode of pile body in underground easily causes construction, once there is Defect Piles, can give and to produce and the duration bring delayed, and bring huge economic loss to construction party, bring potential safety hazard to superstructure.
Therefore, a kind of structure is produced simple, easy to operate, construction and operational efficiency high, energy-conserving and environment-protective, safety factor is high, firmly stable, pile body pile rate is high, save cost, piling mode novel and high-efficiency, pile-driving method breaks through traditional approach, the pouring type pile driver of efficient quick, has wide market prospects.
