Description
Technical field
Bored the present invention relates to the realm of building construction, in specifically efficient pile tube soil, piling, dust, whitewash all-in-one and its
Construction technology.
Background technology
Static pressure pile driver is widely used in China's construction foundation working, due to its using the static pressure of the oil cylinder that pressurizes by coagulation
Native pile tube has the advantages that without friction, noiselessness, speed of application are fast in being directly vertically pressed into stratum, therefore work progress.However,
Geological conditions is not quite similar in construction, often due to the reason such as geology layer of sand is thicker, packing is high, causes stake to reach and set
Meter absolute altitude, or even cut stake.Additionally, the factor such as muck soil moisture content is high, bearing capacity of single pile is low, cohesive soil soil extrusion in construction effect is big
Also the development prospect of Static pressure pile driver is seriously constrained.
Accordingly, it would be desirable to a kind of efficient pile tube in bore soil, piling, dust, all-in-one of whitewashing.
The content of the invention
To solve above-mentioned problem, it is an object of the invention to provide brill soil, piling, spray in a kind of efficient pile tube
Powder, whitewashing all-in-one and its construction technology.Bore in efficient pile tube of the present invention soil, piling, dust, all-in-one of whitewashing, tie
Rationally, easy construction realizes the function of a tractor serves several purposes to structure, reduces machine cost, improves the service efficiency of machine, has
Field is widely applied, and only needs the working procedure can just to reach design and construction depth, both improve efficiency of construction, and
Ensure that bearing capacity of single pile, and the pile body periphery soil body and stake bottom are dusted, after spray operation, a footpath and formation is expanded
Stake bottom enlarged footing, it is to avoid produce differential settlement, reliable in quality, security performance is high.
To reach above-mentioned purpose, the technical scheme is that：
Bored in efficient pile tube soil, piling, dust, all-in-one of whitewashing, including：
Static pressure pile driver：The Static pressure pile driver includes Static pressure pile driver base, and Static pressure pile driver base top is provided with microscope carrier, Static pressure pile driver
