Description
Technical field
The utility model is related to a kind of piling machinery for architectural engineering foundation construction more particularly to a kind of hydraulic-drivens
Guide rod type pile hammer.
Background technology
Pile foundation is a kind of basic shape for being widely used in the architectural engineerings such as ocean engineering, skyscraper, bridge and high ferro
Formula, pile foundation is generally made of the stake being set in soil and the cushion cap of undertaking superstructure, and the effect of stake is to build on top
The load for building object is transmitted on the larger soil layer of depths bearing capacity or squeezes soft layer, to improve the bearing capacity of soil
And compactness, so as to ensure the stability of building and reduce settlement of foundation.
Piling machinery is then to strengthen the necessary equipment of foundation capability by stake injection stratum.Guide rod type diesel pile hammer
One of piling machinery is important, operation principle is similar to single-cylinder double stroke diesel engine, it is pressed in pile cover by hammer seat of plunger
On, it being lifted using cylinder as tup along two guide rods, stake plug is relatively motionless during piling, and then opposite plunger makees spring up and down to cylinder hammer, when
When cylinder hammer moves downward and so that its cylinder holes cover is entered the plunger with plunger ring, then the gas in cylinder chamber is by piston ring packing, cylinder hammer
More moving downward, the gas pressure in cylinder chamber is bigger, gas temperature raising, when reaching certain pressure and temperature, high pressure fuel
