Description
Technical field
The present invention relates to a kind of construction method, be specially a kind of piling Technology.
Background technology
In high-building construction, before architecture construction, it is required for piling and does basis, carry out Construction of High-rise the most again.
By stake and the pile framing that connects stake top, the deep foundation of composition or the single-pile foundation being connected with pile foundation by post, abbreviation pile foundation.High level is built
In building, pile foundation is widely used.Pile foundation construction, after making column pile body with armored concrete, steel, timber etc., with pile sinking machinery
Until watering again after solid soil, or first pore-forming and building up concrete column shape pile body in squeezing into or being pressed into stratum, strengthen pile framing whereby
The technique of bearing capacity.The construction master operation of bored concrete pile is pore-forming and concrete perfusion.Poor for pile foundation geological conditions, as
Fine sand layer in some degree of depth is loose condition (of surface), and strongly weathered sand-rock and middle weathered rock formation locally lie in serious broken (boring
Coring is chunky shape or fragment shape)；Fine sand layer and broken rock all belong to unfavorable geology, easily occur seepage in boring procedure
The phenomenons such as slurry, hole wall collapse, serious still has the situation of a large amount of rubble landing to occur when two is clear, even occurs that collapse hole causes protecting
Cylinder periphery surface depression.For ensureing the smooth pore-forming of pile foundation construction and pile quality, it is necessary to take measures pile foundation surrounding is added
Gu.In existing building foundation construction technology, utilize slurry injection technique to flabbiness ground strengthened be a kind of relatively conventional way.For
The reinforcing of pile foundation, pile foundation is reinforced by the technology that can utilize slip casting also to have document to point out.
But above-mentioned construction thinking needs material resources of employing a tremendous amount of manpower, and efficiency of construction is relatively low.Especially grouting method, if right
Geologic structure detection is not clear, and slip casting is uneven, makes ground have local change, has place not inject, add difficulty of construction.For this
We need to design a kind of technology that pile foundation hole quickly carries out supporting.
Summary of the invention
The present invention is to solve the technical problem that the pile foundation hole in soft foundation is constructed, it is provided that a kind of pile foundation construction skill
Art.
The technical scheme is that a kind of piling Technology uses reaming bit to hole ground, in reaming
Setting casing outside drill bit, between drilling diameter and the casing diameter of reaming bit, gap is 2-4cm, is drilled down at reaming bit
During, adding arc backplate in the space between casing and ground piecewise, described arc backplate is tetragon, described
Four limits be divided into hypotenuse, lower hypotenuse, left hypotenuse, the right hypotenuse, described upper hypotenuse or lower hypotenuse with horizontal plane angle to be,
The arc line shaped that the orthographic projection of described arc backplate presents, and the circle at camber line place is positioned at horizontal plane, camber line to angle be
40-60 °, arc protective plate thickness 2cm, the direction that arc backplate inserts is consistent with the direction that drill bit rotates, and creeps at reaming bit
During, use water that casing inside is washed away process, and constantly will wash away mud extraction with pump, after creeping into end, will
Drill bit and casing are extracted out, arc backplate one complete combined fender pile hole cylinder of composition, are finally irrigated concrete construction.
Compared with prior art, conceptual design of the present invention is reasonable, uses pottery or plastics or tile etc. to hold
Easily arc backplate made by the material of processing, during drill bit creeps into, is sent in boring by arc backplate section by section, forms one
Spiral helicine combination casing.All of arc backplate is stitched together mutually, forms a cylindrical shape, mutually extruding can be formed to
The tubular article of anti-certain pressure, effectively prevents boring from collapsing, gains time for filling concrete and solidification, once construct
Pore-forming, it is not necessary to hole is carried out reprocessing and can carry out pile foundation construction operation, improve efficiency of construction and hole quality.

Fig. 4 is the cut-away view after pore-forming
In figure: 1-ground, 2-reaming bit, 3-casing, 4-arc backplate.
Detailed description of the invention
As schematically shown in Figure 1, a kind of piling Technology, use reaming bit 2 ground 1 to be holed, at reaming bit 2
Outside sets casing 3, and between drilling diameter and casing 3 diameter of reaming bit 2, gap is 2-4cm, is drilled down at reaming bit 2
During, add arc backplate 4, as schematically shown in Figure 2, described arc protective in the space between casing 3 and ground 1 piecewise
Plate 4 is tetragon, and four described limits are divided into hypotenuse a, lower hypotenuse c, left hypotenuse d, right hypotenuse b, as schematically shown in Figure 3, described
Upper hypotenuse a or lower hypotenuse c with horizontal plane angle be, the arc line shaped that the orthographic projection of described arc backplate 4 presents, and camber line
The circle at place is positioned at horizontal plane, camber line to angle be 40-60 °, arc protective plate thickness 2cm, arc backplate insert side
To consistent with the direction that drill bit rotates, in reaming bit drilling process, use water that casing inside is washed away process, and use
Pump constantly will wash away mud and extract out, after creeping into end, drill bit and casing be extracted out, as schematically shown in Figure 4, and arc backplate composition one
Individual complete combined fender pile hole cylinder, is finally irrigated concrete construction.
Claims (2)
1. a piling Technology, uses reaming bit to hole ground, sets casing, reamer outside reaming bit
