Description
Technical field
The invention belongs to stake technical field is planted in dykes and dams crevasse, particularly to a kind of dykes and dams crevasse fast rapid fire stake machine and penetrate stake side
Method.
Background technology
The Emergency Tool that piling machine is commonly used as emergency flood fighting is widely used, often the anxious place of the big flow velocity of dykes and dams crevasse
Need first to drive piles and contain again.
A kind of form of existing piling equipment is hammer piling equipment.Hammer piling equipment includes hammer, and hammer is used for weight
Free-falling, on the upper end of stake, stake is impacted into ground again.Hammer is installed in upright steelframe and utilizes liquid
Pressure lifting assembly lifts in steelframe.Described steelframe can be mounted directly the position that expectation on the ground is hammered to stake
Place.Alternatively, steelframe may be mounted on the chassis of truck, in order to provide mobility for device.Hammer piling equipment
The cost efficiency manufacturing and using is higher, and in the case that hammer piling equipment is movable, then can be relatively easily in piling
Move between place.One major defect of hammer piling equipment is that the repeated impact noise of the upper end to stake for the hammer is very big.Real
On border, hammer can produce ground vibration to the repeated impact of stake, and not only noise is unpleasant for ground vibration, and can result in
Adjacent Buildings and the structural failure of other structures.During piling, the thrust of peening hammer and itself downward inertia cannot fully be released
Put, thus the hitting dynamics of peening hammer is less, piling machine can produce larger vibrations, and operation comfort is poor, and is easily damaged
Part.In addition monkey driver needs the support mechanism of stake, but in dykes and dams crevasse Water discharge flow speed urgency, the equipment of piling and support
Mechanism is difficult to operation.
Another kind of form of existing piling equipment is drilling equipment.It is not to beat stake in ground, but on the ground
Hole to the depth needing, subsequently stake is placed in hole.Drilling equipment combines rotary reamer directed downwardly, this rotary reamer
It is rotatably installed in bracing members frame.This drill is made to rotate by the rotating mechanism of appropriate structuring.This bracing members frame is permissible
It is mounted directly at the position of expectation boring on the ground.Alternatively, bracing members frame, rotary reamer and rotating mechanism are permissible
It is arranged on truck chassis, in order to provide mobility device.
The benefit of drilling equipment is to produce less noise and less not pleasant feeling, and the area around drill site
Less potential damageability vibration is produced in domain.Use in extensive piling operation for the drilling equipment is also efficient.Use
The shortcoming of drilling equipment is: compared with hammer piling equipment, drilling equipment generally has higher running cost.Carry out with to stake
Hammering is compared, and boring is also required to expend more times.Also must reserved area be nearby temporarily set, to place backfill stake holes
The soil being used.For the piling of dykes and dams dam breach position, to race against time be unfavorable for this.
The overall shortcoming of existing piling equipment is that to move to another piling place from a piling place more time-consuming, at present
Piling equipment need closely to drive piles, this is all unpractical in the piling of dykes and dams crevasse, and the frequently movement of piling machine can be made
Become waste of time, inefficiency, this is totally unfavorable to the timely repairing of dykes and dams crevasse.Flood-fighting work as you know
Needs strive point more than second, often lose one minute and be likely to cause huge loss.It is badly in need of exploitation one kind can continuously drive piles for this,
And the piling machine that can drive piles at a distance.
Content of the invention
In order to solve the deficiency of above-mentioned prior art, the purpose of the present invention is: provides a kind of dykes and dams crevasse fast rapid fire stake machine
And penetrate piling method, fast and effectively drive piles, many piles once can be conveniently installed, because its trigger mechanism is mounted in
It is possible to by the length of adjustment telescopic arm, realize continuous piling, without every dozen of piles on the support base of telescopic arm
Just stop work and move piling machine, be that valuable time has been striven in flood-fighting.
