Description
Technical field
The utility model relates to the used rig of drilling construction of slope protection pile in a kind of deep foundation pit support engineering, particularly a kind of long-spiral replaceable and extruded borehole rig.
Background technology
Along with the continuous development of urban architecture, the bodily form of building is also constantly developing to super largeization, superelevationization, super in-depth.Because the progressively intensification of the excavation of foundation pit degree of depth, the difficulty of its pattern foundation pit supporting structure is also increasing, especially at the west of Beijing area half ubiquity one deck sand pebble layer, be characterized in that thickness is big, density is high, particle diameter is big, the big difficulty of bringing for the pore-forming of long-spiral drilling machine, make many engineerings can't adopt long-spiral drilling machine to carry out pore-forming, have to adopt other hole forming method.How to improve the pore-forming technique of long-spiral drilling machine, the application that makes it in sand pebble layer is expanded, and is the key that improves the long-spiral drilling machine function of use.
From early eighties, the drilling construction of slope protection pile generally adopts hand excavated pile in the deep foundation pit support engineering of Beijing area, as long as the quality control on construction of retaining wall is good, pore-forming is no problem in sand pebble layer when running into sand pebble layer.Because soil body landslide in the hole often takes place in hand excavated pile in work progress, retaining wall caves in, accidents such as thing, toxic gas are weighed down in the aperture, in view of there being more problem aspect the construction safety, Beijing relevant department has taked the hand excavated pile license granting mechanisms in the early 1990s, begin to limit the construction of hand excavated pile, encourage to adopt mechanical hole building.
The job practices of long spiral pore-forming begins progressively to promote in the nineties, easy construction, speed are fast because long-spiral drilling machine construction has, friction, noiselessness, characteristics such as pollution-free, have therefore obtained using more widely in the foundation pit supporting project construction.But continuous intensification along with the Beijing area excavation of foundation pit degree of depth, it is more and more darker that the long-spiral drilling machine pore-forming enters the degree of depth of sand pebble layer, therefore the density and the particle diameter of cobble is also increasing in the sand pebble layer, makes that long-spiral drilling machine difficulty of pore-forming in sand pebble layer is more and more higher.Concrete distribution situation is that relatively difficulty of long spiral pore-forming is adopted usually because the buried depth of sand pebble layer is superficial, and the density of cobble and size ratio are bigger in the sand pebble layer in area to the west of the Wu Ke Song, generally adopts modes such as manually digging hole, impact holing.The Wu Ke Song is with in this zone to the west of the street, Xidan, the buried depth of sand pebble layer is generally about 10.00～15.00M, some local still sand pebble layer and argillic horizon are mutual, there is the multilayer sand pebble layer, after long spiral depth of pore forming surpasses 15.00～20.00M (counting) from natural ground, the penetration rate of rig drilling construction is more and more slower, and the difficulty of pore-forming is more and more higher.The long-spiral drilling machine subject matter that pore-forming runs in sand pebble layer has:
1, the content of cobble is higher in the sand pebble layer, and drilling tool is drilling depth not;
2, when cobble particle diameter in the sand pebble layer was big, the cobble band of big particle diameter did not come up in the pore forming process, often causes bit bouncing, bit freezing phenomenon;
3, when sand pebble layer is thicker, relatively poor because of its self-support, it is serious to put forward the hole phenomenon of collapsing behind the brill;
4, when containing a small amount of backwater or residual water in the sand pebble layer, very easily form quicksand, the stake hole hole phenomenon of collapsing is serious, and the slope protection pile drilling construction is difficulty very.
Summary of the invention
The purpose of this utility model is deficiency and the defective that solves the drilling construction method of slope protection pile in the domestic existing deep foundation pit support engineering, propose a kind of can be by large diameter cobble being extruded into both sides and being discharged from, and guarantee that hole wall is stable, slick and sly, be not prone to phenomenons such as the hole of collapsing, bulge, reduce construction cost, reduced the long-spiral replaceable and the extruded borehole rig that in sand pebble layer, adopt the potential safety hazard of manual digging pile construction in the past.
