Description
Technical field
The present invention relates to building pile foundation technical field, more particularly to a kind of interior rig and its construction method.
Background technology
With the continuous development of industry, all kinds of high-rises and complicated structure type are emerged in an endless stream, and pile foundation is wanted
Also more and more higher is sought, various new technologies, the Prefabricated hollow pile of new material gradually substitute traditional pile foundation form, also therefore increasingly
It is obvious to find in many engineering projects at home, using existing construction equipment (such as static pressure equipment, hammering equipment) prefabricated
It is difficult to during hollow sunk pile through thicker dense sand stratum geology, pile body damages or do not reached design stake when constructing often
It is long, lead to not the requirement for meeting engineering.Also there are some other engineering methods at present to solve the Prefabricated hollow pile construction problem occurred,
Such as the methods of drawing hole construction, stirring lock pin, although solving above-mentioned produced problem to a certain extent, need on construction ground
More construction equipments are additionally launched, cost is higher, and efficiency of construction is more general, have impact on the cycle of engineering.
Patent " drawing hole static pressure enters rock construction technology certainly at hugging pressure type PHC pipe piles end " (CN200610124487.X) is to pass through
High-Pressure Water and high pressure draught impact and crushed the hard gravel layer in pile top front end, successively form hole, side punching press.It is this
High-pressure rotary-spray (no drilling rod) draws the structure for entering rock construction method, destroying original pile-end soil in hole, and the bearing capacity at stake end is lost
Greatly.
Patent application " pipe inside spin draws hole and the progressive static pressure pile-sinking construction technology of static pressure pile-sinking alternatively, sectionally "
(CN200910186602.X) a kind of, patent application " dug in static pressure and pressing pile construction method dug in pile press machine and static pressure "
(CN201010278241.4), patent " drawing cellular type Static pressure pile driver " (CN201220548408.9) is on existing static pressure machine
Fixed frame is installed, drawing hole construction is promoted by hydraulically extensible, first draws pitching pile, the constructing operation of piling behind hole, belongs to Contiuum type
Or monoblock type stake machine, this have impact on original machine structure and the use in later stage, the easily collapse hole, and can not accomplish to draw in construction
Hole is carried out simultaneously with piling, and does not carry out gas injection construction, need to be installed bigger power set, low construction efficiency, can not be ensured stake
The bearing capacity and pile sinking quality at end.
The content of the invention
To overcome problem above, the present invention provides a kind of split type interior rig and its construction method, can effectively solved pre-
The technical problem that hollow pile processed runs into when layer of sand is constructed.
The present invention adopts the following technical scheme that：
A kind of interior rig, including digging-drilling machine, the digging-drilling machine include reductor, fixture, drive device and drilling tool, and fixture is set
