Abstract
The series filling piles using internal auger drilling include filling pile, pedstal pile and ribbed pile, and technically features that twist drill is used to drill hole and a spiral conveying system for discharging earth has an external tube (sleeve tube) in which there is an auger stem. It is suitable for long pile with big diameter.
Description
The present invention relates to the foundation pile and the band flank stake that is used for pattern foundation pit supporting structure of construction work.
Existing auger boring equipment has advantages such as speed of fulfiling hole is fast, noiselessness, friction, mud-less pollution.But because equipment dynamic restriction, the long and stake footpath of the stake of augered pile is very limited.The present invention will add upper exterior tube and adopt the major diameter drill bit to address this problem at the minor diameter auger stem.The pattern foundation pit supporting structure and the antiseepage problem of existing building are more and more important.The present invention loads onto high compression set spray apparatus on the outer tube of inside spin drilling equipment, can make flank on the band of castinplace pile side.Band flank soldier pile not only can reduce cost but also can reach anti-seepage effect.In order further to improve the bearing capacity of foundation pile, the present invention can be provided with enlarged body on castinplace pile, and together constitutes the expansion stake with castinplace pile, thereby further improves the supporting capacity of foundation pile.
The objective of the invention is to propose inside spin drill-pouring pile series and job practices thereof and construction equipment.
Inside spin drill-pouring pile series of the present invention comprises that inside spin bored pile, inside spin boring enlarge stake and the stake of inside spin boring band flank.
The inside spin bored pile comprises non-solid wall stake and solid wall stake.
The non-solid wall stake of inside spin bored pile is identical with the structure of existing castinplace pile, and solid wall stake is the composite pile that is made of jointly solid parietal layer of hole wall and inner pile body.Gu parietal layer can or distribute one section at least along the distribution of boring total length.
It is that the enlarged body that pile body and high-pressure injection by auger boring pouring pile form constitutes jointly that inside spin boring enlarges stake, and contains an enlarged body at least.
The stake of inside spin boring band flank is to be made of jointly the pile body of inside spin bored pile and the mixture that adopts high compression set spray on this pile body side, its pile body is made up of a kind of material at least, be made up of concrete than epimere pile body in sending out, the hypomere pile body is made up of the mixture of clay and cement.
The pile body hole forming method of inside spin drill-pouring pile series is to fetch earth with augers, fails soil with auger stem and the helical conveyer system that is enclosed within its outer outer tube composition.
The one-tenth holes protecting wall mode of inside spin drill-pouring pile series is divided into no retaining wall pore-forming and the retaining wall pore-forming is arranged
When soil layer need not retaining wall, the direct pore-forming of available inside spin drilling equipment
There is the retaining wall pore-forming to be divided into slurries retaining wall pore-forming, pillar retaining wall pore-forming and solid wall retaining wall pore-forming
Slurries are meant mud or stabilizing solution, have sealing to be meant between the bottom of inside spin drilling equipment and the hole wall and are sealed.Not having sealing is meant between the bottom of inside spin drilling equipment and the hole wall and does not establish sealing.
Pillar retaining wall pore-forming be outside auger stem or the inside spin drilling equipment outside have pillar, this pillar directly contacts with the soil body, to prevent the soil body hole of collapsing
Gu wall retaining wall pore-forming is in the inside spin boring procedure, and is with cementing material that drill hole wall is fixed, to prevent the hole of collapsing.
After finishing boring, concrete method for filling can be divided into: 1, directly the concrete example is gone in the boring.2, concrete perfusion in pillar.3, with conduit concrete perfusion or concrete is pressed in the boring by rigidity or flexible conduit in boring with pump.4, carry drilling rod to boring inner edge compressed water slurry limit, after after proposing drilling rod, in boring, pouring stone into or pour stone into, be pressed into mortar in the boring with the mortar conduit again and put and draw out cement paste, or the limit pours stone into, mortar is injected with the mortar conduit of band vibrating device in the limit.
Gu the job practices of wall retaining wall: but from the churning mouth of outside of sleeve or have grouting port and telescopic stirring vane or sleeve pipe outside, in soil layer or hole, inject at least a cementing material, the rapidly solidified hole wall of this cementing material energy among then the grouting port.
The job practices of enlarged body: but one of method is with the high-pressure injection cementing material, but the soil body is mixed with cementing material, mix enlarged body thereby constitute.Two of method be with high-pressure spray cut soil and the native sucking-off hole that will be cut with pump outside, thereby constitute expansion space.This expansion space promptly constitutes the perfusion enlarged body after being filled by concrete.Three of method is because loosened soil or sediment are often arranged at the bottom of perfusion enlarged body, thereby influences bearing capacity.This method is to spray cementing material among loosened soil or sediment, and this part soil body is mixed with cementing material.Its top is still expansion space, mixes enlarged body thereby constitute perfusion.
The job practices of band flank stake: in the inside spin boring procedure, spray slurry with the high compression set spray shower nozzle that is located at sleeve bottom in the soil body, thereby make the slurry and the soil body constitute mixture, this mixture is the flank of band flank stake, after treating that pore-forming is finished, can carry out the pile body construction of castinplace pile.
The construction equipment of inside spin drill-pouring pile series: have pile frame, running gear, control system and have a cover jacking system and a dynamical system at least.It is characterized in that drilling equipment is to have outer tube in the auger stem outside and its outer tube can be sleeve pipe or pillar, auger stem can be latus rectum or reducing, outer tube all is set or is provided with one section at least along auger stem is elongated, when outer tube did not contact with the unit head part, outer tube should be fixed together with auger stem.
When need are more constructed the solid wall stake of inside spin boring or inside spin boring expansion stake or the stake of inside spin boring band flank, a medium channel should be set at least on the inside spin drilling equipment then
With accompanying drawing some embodiment among the present invention are described:
