Description

A kind of piling Technology
Technical field
The present invention relates to a kind of construction method, specially a kind of piling Technology.
Background technique
In high-building construction, before architecture construction, requires piling and do basis, then carry out Construction of High-rise again. By the pile framing of stake and connection stake top, the deep foundation of composition or the single-pile foundation being connect by column with pile foundation, abbreviation pile foundation.High level is built In building, pile foundation is widely used.Pile foundation construction, after column pile body is made with armored concrete, steel, timber etc., with pile sinking machinery It squeezes into or is pressed into stratum until being poured again after solid soil, or first pore-forming and build up concrete column shape pile body, reinforce pile framing whereby The technique of bearing capacity.The construction master operation of bored concrete pile is pore-forming and concrete perfusion.It is poor for pile foundation geological conditions, such as exist Fine sand layer in some depth is in loose condition (of surface), and serious broken (drilling is locally present in strongly weathered sand-rock and middle weathered rock formation Coring is in chunky shape or fragment shape);Fine sand layer and broken rock all belong to unfavorable geology, easily leak in boring procedure Slurry, hole wall phenomena such as collapsing, it is serious still to have the appearance of the case where a large amount of rubbles landing when two is clear, or even collapse hole occur and cause to protect Cylinder periphery surface depression.To guarantee the smooth pore-forming of pile foundation construction and pile quality, it is necessary to take measures to add pile foundation surrounding Gu.In existing building foundation construction technology, using slurry injection technique to it is flabbiness ground strengthened be a kind of relatively conventional way.For The reinforcing of pile foundation also has document to point out that the technology that can use slip casting reinforces pile foundation.
But above-mentioned construction thinking needs material resources of employing a tremendous amount of manpower, construction efficiency is lower.Especially grouting method, if right Geologic structure detection is unknown, and slip casting is uneven, and ground is made to have local change, has place not inject, increases difficulty of construction.Thus We need to design a kind of technology that supporting is quickly carried out to pile foundation hole.
Summary of the invention
The technical issues of present invention is in order to solve the construction of the pile foundation hole in soft foundation, provides a kind of pile foundation construction skill Art.
The technical scheme is that a kind of piling Technology, drills to ground using reaming bit, in reaming Casing is set on the outside of drill bit, gap is 2-4cm between the drilling diameter and casing diameter of reaming bit, is drilled down into reaming bit During, arc backplate is added in the gap between casing and ground piecewise, the arc backplate is quadrangle, described Four sides be divided into bevel edge, lower bevel edge, left bevel edge, right bevel edge, the upper bevel edge or lower bevel edge angle with horizontal plane be, The arc line shaped that the orthographic projection of the arc backplate is presented, and the circle where camber line is located at horizontal plane, camber line pair angle be 40-60 °, arc guard plate thickness 2cm, the direction of arc backplate insertion is consistent with the direction that drill bit rotates, and creeps into reaming bit In the process, casing inside is carried out using water washing away processing, and will constantly washes away mud extraction with pump, it, will after drilling Drill bit and casing extraction, arc protective board group are finally irrigated concrete construction at a complete combined fender pile hole cylinder.
Compared with prior art, conceptual design of the present invention is reasonable, is held using ceramics or plastics or tile etc. Arc backplate is made in the material of easy processing, and during drill bit drilling, arc backplate is sent into drilling section by section, forms one Spiral helicine combination casing.All arc backplates are stitched together mutually, form a cylindrical shape, mutually squeeze can be formed to The tubular article of anti-certain pressure effectively prevent drilling to collapse, and gains time for filling concrete and solidification, primary to construct Pore-forming, pile foundation construction operation can be carried out by carrying out reprocessing without device to hole, improve construction efficiency and hole quality.

Specific embodiment
As schematically shown in Figure 1, a kind of piling Technology drills to ground 1 using reaming bit 2, in reaming bit 2 Outside sets casing 3, and gap is 2-4cm between 3 diameter of drilling diameter and casing of reaming bit 2, is drilled down into reaming bit 2 During, arc backplate 4 is added piecewise in the gap between casing 3 and ground 1, as schematically shown in Figure 2, the arc protective Plate 4 is quadrangle, and four sides are divided into bevel edge a, lower bevel edge c, left bevel edge d, right bevel edge b, as schematically shown in Figure 3, described Upper bevel edge a or lower bevel edge c angle with horizontal plane be the arc line shaped that the orthographic projection of the arc backplate 4 is presented, and camber line The circle at place is located at horizontal plane, camber line pair angle be 40-60 °, arc guard plate thickness 2cm, the side of arc backplate insertion To consistent with the direction that drill bit rotates, in reaming bit drilling process, casing inside carried out using water to wash away processing, is used in combination Pump will constantly wash away mud extraction, after drilling, drill bit and casing be extracted out, as schematically shown in Figure 4, arc protective board group is at one A complete combined fender pile hole cylinder, is finally irrigated concrete construction.
