Description
Technical field
The present invention relates to the dedicated stake field of foundation engineering, the processing unit of specially a kind of cast-in-situ bored pile stone and its
Application method.
Background technique
In pile foundation engineering bored pile construction, since the characteristics of its construction method, is bored using drilling machine drilling and forming hole
Head rotation will stir into mud after soil body chopping, friction plus water, make drill bit be able to continue to bore using slush pump extraction stake holes
Into.But in the more complex place of certain geology, native stone mixing is mingled with more crushed stone, sundries, will affect the drilling of drill bit, and
And stone can not be bored by drill bit it is broken can only be as drill bit the more bores the more deep, until last stone is all deposited on a bottom, until final
Cause drill bit that can not creep into, designing pile length deficiency, influences a substrate amount.Therefore it needs in drilling construction to the stone in stake position
It is handled.Since traditional rotary drilling rig boring extracting soil is whole soil, stone and the water taken out in stake position, lead to nothing in stake holes
Slime water can be supported protection to stake holes hole wall, therefore this method is unfavorable for the construction of cast-in-situ bored pile in weak soil.
Summary of the invention
In order to overcome the drawbacks of the prior art, a kind of easy to operate, adaptable, safe and reliable foundation structure structure is provided
Part, the invention discloses the processing units and its application method of a kind of cast-in-situ bored pile stone.
The present invention reaches goal of the invention by following technical solution:
A kind of processing unit of cast-in-situ bored pile stone, including drilling rod, it is characterized in that: further including spinner handle and compression bar, spinner handle is by each
Stock spinner handle unit successively join end to end composition and it is wavy, spinner handle is fitted on the lateral surface of drilling rod bottom with central axis, bore
The two sides of bar are the wave crest and trough of spinner handle respectively, and each compression bar is successively fitted on the central axis of spinner handle and is fixed on spinner handle
On the lateral surface of drilling rod.
The processing unit of the cast-in-situ bored pile stone, it is characterized in that:
Spinner handle selects wirerope, and the outer diameter of wirerope bends wirerope by stock in 20mm~40mm, and every bending is primary to form one
Stock spinner handle unit；
Compression bar selects reinforcing bar, and the spinner handle unit number of share of stock of every compression bar fitting is not less than ten strands, and the outer diameter of compression bar is in 6mm~8mm.
The application method of the processing unit of the cast-in-situ bored pile stone, it is characterized in that: successively implementing as follows:
Drilling rod with spinner handle as last root drilling rod of drilling machine and is set at the bore position of bored concrete pile, starts drilling machine, makes to bore
Bar drives spinner handle to drill out priming concrete pile hole, and drilling rod bores soil and directly passes through rotation by spinner handle at the stone to leak down in drilling rod when priming concrete pile hole
It is expressed into the soil body of priming concrete pile hole surrounding side wall, the synchronous decline of the propulsion without drilling with drilling rod avoids bored concrete pile
Hole the more is bored the more deep and stone is gradually accumulated in hole.
The application method of the processing unit of the cast-in-situ bored pile stone, it is characterized in that: the height of spinner handle, that is, wave crest peak
Top each point links to 1.2~1.5 times that the distance between trough the lowest point each point line is priming concrete pile hole aperture.
The invention has the following beneficial effects:
1. solving the problems, such as to drill through priming concrete pile hole inner concrete block, stone influence pile foundation construction and quality；
2. material is easy to get, wirerope can be using discarded wirerope, and wirerope should have certain stiffness and strength, so as to energy
Enough push stone；
3. it is easily manufactured, it is easy-to-use, it is adaptable.
Detailed description of the invention
Fig. 1 is main view of the invention；
Fig. 2 is the sectional view along A-A in Fig. 1.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
Embodiment 1
A kind of processing unit of cast-in-situ bored pile stone, including drilling rod 1, spinner handle 2 and compression bar 3 are as depicted in figs. 1 and 2, specific to tie
Structure is:
Spinner handle 2 is successively joined end to end by each stock spinner handle unit 21 to be constituted and wavy, and spinner handle 2 is fitted in drilling rod 1 with central axis
On the lateral surface of bottom, the two sides of drilling rod 1 are the wave crest and trough of spinner handle 2 respectively, and each compression bar 3 is successively fitted in spinner handle 2
Spinner handle 2 is weldingly fixed on the lateral surface of drilling rod 1 on central axis.
In the present embodiment:
Spinner handle 2 selects wirerope, and the outer diameter of wirerope bends wirerope by stock in 20mm~40mm, and every bending is primary to be formed
One spinner handle unit 21, the height of spinner handle 2, i.e. wave crest summit each point link to the distance between trough the lowest point each point line, such as
It is 1.2~1.5 times of priming concrete pile hole aperture in Fig. 1 shown in a.；
Compression bar 3 selects reinforcing bar, and 21 number of share of stock of spinner handle unit of every compression bar 3 fitting is not less than ten strands, the outer diameter of compression bar 3 6mm~
8mm。
The present embodiment in use, as follows successively implement: by with spinner handle 2 drilling rod 1 as drilling machine last
Root drilling rod is simultaneously set at the bore position of bored concrete pile, starts drilling machine, makes drilling rod 1 that spinner handle 2 be driven to drill out priming concrete pile hole, and drilling rod 1 bores
Soil at the stone to leak down in drilling rod 1 when priming concrete pile hole directly by spinner handle 2 by rotary squeezing to priming concrete pile hole surrounding side wall
In the soil body, without the synchronous decline of the propulsion that drills with drilling rod 1, priming concrete pile hole is avoided the more to bore the more deep and stone gradually heap in hole
Product.
