Manual digging pile construction operating procedure is simple, easy for construction, bearing capacity of single pile is high, construction quality is easily guaranteed that.But
Caisson underground work condition is poor, the security risk of bad environments, large labor intensity, single pile speed of application slowly, in construction
It is very prominent, it is necessary to take underground work, human safety issues are extremely severe, and there are many unsafe factors and hidden danger, apply
Work safety management difficulty is larger；And stake well digging process weakens slip mass drag itself, especially digs to below slider bed
When hard and steady stratum, it usually needs explosion is big to the disturbance on stratum；Especially those are in the cunning in development of deformation stage
Slope, explosion more exacerbate its unstability and construction risk, and the safety of construction personnel and periphery construction of structures is even more to be difficult to ensure.
Mechanical hole perfusion post construction efficiency is high, operator is few, risk is small, is influenced less by weather, but in square pile
There is also some technical problems when construction, and such as most rotary digging stakes use circular bite currently on the market, in addition market
The problems such as rectangular friction pile mechanical piling technique of upper appearance is immature, applicability is not strong or construction cost is excessively high exists.
Economic and Efficiency Analysis shows that (reason is to collapse although mechanical hole building increases compared with the concrete that artificial digging pile needs
Hole and fullness coefficient increase), but the steel reinforced concrete dado of artificial digging pile can be reduced simultaneously, increased costs are less, are substantially at and hold
Level state.
Construction risk can be greatly lowered with respect to manually digging hole in rectangle friction pile mechanical hole building, as collapsed during manually digging hole
The emergency situations such as hole, electric shock, gas explosion improve construction efficiency, accelerate construction progress, solve manual digging pile construction progress
Slowly, the big problem of risk has preferable market application prospect.

Execute step A.4.2~A.4.3, until the Delta Region that the adjacent drilling profile bored lower twice is surrounded with rectangle stake holes contour line
Until a quarter of the height no more than rectangle stake holes contour line bond length；
A.4.5 A.4.2 referring to step, as the drilling profile bored under first and second times cannot be enclosed with rectangle stake holes contour line
At Delta Region, then third time pile digger drill core position is located on short side center line, is particularly located in the short side for not excavating region
The center position of heart line, then execute step A.4.4~A.4.5；
Rectangle steel pile casting of the present invention is overall length casing, and steel pile casting interface size is equal with rectangle stake holes contour line,
Length is identical as rectangular pile depth.
The concrete that region pours of backbreaking on the outside of the steel pile casting uses the plain concrete of C15 grade, rapid-hardening.
Described removes the extra earthwork of side wall, the Delta Region that do not cut comprising rotary digging stake and the bottom slump soil body.
In step F, propose that steel pile casting need to carry out after the concrete final set that region of backbreaking pours using manipulator.
Construction method of the present invention has the beneficial effect that
Construction method of the present invention solves artificial digging pile and is crushed into rock inefficiency, and does not allow in the case where environment is complicated quick-fried
Digging is broken, the very big problem of drilling construction difficulty only need to not increase construction cost, and have using conventional rotary drilling machinery equipment
There are the advantages such as speed of fulfiling hole is fast, construction efficiency is high, easy to operate, security risk is low.
