Description
Technical field
The present invention relates to foundation construction field of engineering technology, more specifically to a kind of high water spray earth coagulation
Soil pressure fills the engineering method of built pile.
Background technology
In recent years, capital construction scale constantly expands, at soil such as building, water conservancy, electric power, traffic and railways
During wood engineering is built, various unfavorable foundations need to carry out basement process and could meet and build top and build (structure) and make
The requirement of thing, method for processing foundation be selected to control construction quality, reduce construction costs essential condition.
The method of basement process is varied, and wherein rotary churning pile, concrete guncreting pile (also known as CFG stake) are in recent years
Grow up and process the new method of soft subgrade, this pile-type because having excellent technical performance and economic effect,
Promote the use of at home.
Rotary churning pile belongs to Half rigid pile, and pile strength is low, and deformation modulus is little, complex ground treatment pile body pressure-bearing
Time, expansion damage easily occurs.CFG stake belongs to rigid pile, and pile strength is high, and deformation modulus is big, but at present
Composite foundation treatment typically uses paxilla footpath, at the bottom of bearing capacity of single pile, it is impossible to realizes large pile spacing and lays out pile, unit ground
Base processing area stake content is higher, and geographical processing cost can not be greatly lowered.
Summary of the invention
The technical problem to be solved is to provide a kind of high spraying cement earth concrete pressure to fill built pile
Engineering method, to solve above-mentioned technical problem.
A kind of high spraying cement earth concrete pressure that the present invention proposes fills the engineering method of built pile, comprises the steps:
After S1, multifunctional drill are in place, starting drilling machine construction, drilling tool creeps into completing drilling construction at the bottom of hole；
Start heavy jet grouting device, carry brill and start height spray, stirring concrete earth construction；High spray stirring construction is to designing position
Putting, high water spray earth pile driving construction is complete；
After high water spray earth pile driving construction completes in S2, S1, transfer drilling tool to design attitude at the bottom of hole, startup coagulation
Soil pressure filling device, starts coagulation soil pressure and fills construction, and coagulation soil pressure fills high to stake top mark, and coagulation soil pressure has filled,
The highest spraying cement earth concrete pressure fills built pile and has constructed.
Preferably, cement earth pile and concrete guncreting pile can realize combining, lower combination, many combinations and complete
The composite type of combination.
A kind of high spraying cement earth concrete pressure that the present invention proposes fills the engineering method of built pile, utilizes multifunctional drill,
Use long spire pore-forming, utilize the spray of major diameter, many head heights, agitating device, it is achieved the spray of soil cement height, stirring
Compound；High water spray earth has been constructed, and realizes coagulation soil pressure with position at the bottom of discharge hole under drilling tool and fills construction, coagulation
Soil pressure has filled, and high spraying cement earth concrete pressure fills built pile and constructed.This pile-type collection soil cement side frictional resistance
Power is big, and the big two aspect advantages of bored concrete pile rigidity, so that bearing capacity is better than cement earth pile and bored concrete pile, single pile
Bearing capacity, shearing resistance are greatly improved.Because this pile-type top is composited by CFG stake core stake and soil cement,
Stake end cross-sectional area increases, it is achieved large pile spacing lays out pile, and reduces unit basement process area king-pile content, reduces and throws
Money, cost-effective, duration can be greatly shortened simultaneously.
The present invention utilizes multifunctional drill to realize height water spray earth with cast-with-pressure concrete pile (CFG stake) by single
A machine technique pile of conversion, construction technology is simple, workable, it is simple to quality control, economic and environment-friendly,
Low cost, comprehensive benefit are notable.Unit is constructed, and equipment investment amount is few, and equipment use cost is low；Because height sprays
Using major diameter, bull shotcrete construction, speed of application is fast, and the duration is short, high efficiency；Because construction pore-creating is for long
Spiral is constructed, and the geological conditions suitability is strong, is suitable for bad ground construction；This pile-type bearing capacity is high, settles little,
Construction technology is simple, workable, it is simple to quality control, detection, properties are notable；Promote the use of
Bigger social and economic benefits will be brought.
