Abstract
A kind of dry feature that fetches earth energy-conservation down-hole hammer castinplace pile is: stake footpath 500-1000mm, the long <90m of stake, pile body upper soil horizon is completed by pipeline sinking pile machine or long-spiral drilling machine or the two collocation, pile body bottom hard rock, by energy-conservation down-hole hammer rig rock drilling pore-forming, then place the reinforced concrete pile of reinforcing cage and concrete perfusion.Its apparatus characteristic is in down-hole hammer impactor upper end, to be provided with permeable rock dust ballast aggregate bin, and drilling rod is polished rod under polished rod or upper spiral.Compare with existing down-hole hammer, no matter the tens of rice of hole depth also only needs 2 25m
3/ minute air compressor machine, whole pile Energy Consumption of Construction reduces by 50%, and equipment continuous productive process improves one times of work efficiency; Compare with percussive drill, mud-less pollution not only, more importantly work efficiency improves 8-10 doubly, completes a pile from several days, develops into and within one day, completes 5-10 pile.
Description
Technology neck city
Utility model relates to building foundation field, relates in particular to a kind of dry energy-conservation down-hole hammer castinplace pile and equipment thereof of fetching earth.
Background technology
At home in pile foundation engineering, common seashore, Bian Huo hilly ground, mountain, pile foundation top is tens meters to tens meters thick sandy soil layers or Soft Soil Layer, and end is hard rock more than 50MPa, and as bearing stratum, design specifications requires into rock 1-3d, or more.At present, the conventional percussive drill construction of this class engineering, must take one to three day time in order to enter rock.
Down-hole hammer rig belongs to high energy consumption; Depth of pore forming 10-25m, needs 20-25m
3/ minute, 2 of the air compressor machines of 180kw power, add unit head 90-110kw on a machine, lower unit head 180-220kw, needs 630-670kw altogether.And the every increase of hole depth 10m, increases 20-25m
31 of/minute air compressor machine, therefore, hole depth surpasses 35m, in China, is to be constructed by percussive drill with several tons of weight heads substantially.
Utility model content
The purpose of this utility model is to provide a kind of dry energy-conservation down-hole hammer castinplace pile and equipment thereof of fetching earth, can be by pile body upper soil horizon pore-forming, the pipeline sinking pile machine of fast, the dry operation of, speed low by construction cost or long-spiral drilling machine or the two collocation complete, the pore-forming of pile body end hard rock, is completed by energy-conservation down-hole hammer rig.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of dry feature that fetches earth energy-conservation down-hole hammer castinplace pile is: stake footpath 500-1000mm, the long <90m of stake, pile body upper soil horizon is completed by pipeline sinking pile machine or long-spiral drilling machine or the two collocation, pile body bottom hard rock, by energy-conservation down-hole hammer rig rock drilling pore-forming, then place the reinforced concrete pile of reinforcing cage and concrete perfusion.
A kind of equipment of the dry energy-conservation down-hole hammer castinplace pile that fetches earth like the prior art, all there is air compressor machine, high pressure airline hose, unit head, drilling rod, impactor and chisel head, it is characterized in that: in down-hole hammer impactor upper end, be provided with permeable rock dust ballast aggregate bin, aggregate bin bottom or side are established discharging switch, and drilling rod is polished rod under polished rod or upper spiral.Aggregate bin number is depending on muck removal amount, and aggregate bin back cut diameter equals or is not equal to diameter at the bottom of lower bucket.
No matter domestic abroad, existing down-the-hole hammer drill machine technology only considers ballast to go out the tap of ground at the bottom of tens meters of dark holes, so power, wind speed, air quantity can constantly increase along with the increase of the degree of depth.In Code For Design of Building regulation: entering rock stake is end bearing pile, its draw ratio≤80, so 0.6-0.8m be take as main in the stake footpath of China's wide geographic area architectural design, enter rock 1-3d (stake footpath), and rock dust ballast volume is 0.3-1.3m only
3, in fact, after rock drilling pore-forming, muck removal again while proposing drilling tool.With 2 air compressor machines, drive downhole hammer rocks like this, then ballast is blown to high several meters, and to fall into aggregate bin be energy-conserving product.When the water yield is larger in hole, above aggregate bin, establishes minor diameter submersible pump and draw water.
The utility model is compared with existing down-hole hammer, no matter the tens of rice of hole depth also only needs 2 25m
3/ minute air compressor machine, whole pile Energy Consumption of Construction reduces by 50%, and equipment continuous productive process improves one times of work efficiency; Compare with percussive drill, mud-less pollution not only, more importantly work efficiency improves 8-10 doubly, completes a pile from several days, develops into and within one day, completes 5-10 pile.
Accompanying drawing explanation
Fig. 1 is the embodiment generalized section of the utility model castinplace pile.
In Fig. 1: 1. basement bottom board, 2. layer of sand, 3. cushion cap, 4. goes up pile body, 5. mud, 6. argillic horizon, 7. descends pile body, 8. granite.
Fig. 2 is the generalized section of the utility model aggregate bin and down-hole hammer part.
9. the drilling rod of central airway, 10. aggregate bin, 11. impactors, 12. chisel heads.
The specific embodiment
As Fig. 1 and Fig. 2, the construction sequence of an exemplary embodiments of the utility model is as follows:
1. according to Fig. 1, embodiment geology is weak soil, if do not allowed soil compaction, two case pile machines are stood on stake position, shake heavy two sleeve pipes through layer of sand (2) and mud (5), extremely compared with hard viscosity layer (6), quiet pull out interior tube vibration unload soil or open folding inner tube pin unload soil outside hole, stay outer tube guard aperture; As allow soil compaction, and single pipeline sinking pile machine is stood on to stake position upper, immersed tube lower ending opening, and be placed in low grade element concrete pile top, the heavy single immersed tube that shakes, to compared with hard viscosity layer (), stays steel immersed tube guard aperture, and pipeline sinking pile machine moves to next position and continues construction;
2. long-spiral drilling machine is stood on to a limit, hole, from steel immersed tube bottom compared with hard viscosity layer (6), creep into granite (8) face, mention drilling tool, rig moves next position construction (without weak soil by the direct pore-forming of long-spiral drilling machine);
3. energy-conservation down-hole hammer rig is stood on to a limit, hole, the down-hole hammer of band chisel head (12) and impactor (11) is put into bedrock surface from steel immersed tube, start air compressor machine, compressed air acts on impactor (11), drive again chisel head (12) that granite (8) is cut a hole broken, the compressed air of discharging is upwards blown into aggregate bin (10) by rock dust ballast, until cut a hole to design elevation;
4. mention aggregate bin (10), impactor (11) and chisel head (12) that rock dust ballast is housed and unload quarrel outside stake hole, then move to next position construction;
5. by existing technology to install reinforcing cage in hole with fill with concrete, complete the construction of a basic utility model castinplace pile, go round and begin again, complete the construction of all the utility model castinplace piles.
