Principle about pile pulling is as follows:
1. broken cushion cap is with being exposed by 26 of pile pullings that need are pulled out;
2. imbedded the steel casing of establishing greater than sleeve pipe 17 diameters by the position of 26 of pile pullings, and with all backfills of soil, compacting around the steel casing, I type extractor does not sink when guaranteeing to construct;
3. be welded into greater than the sleeve pipe of being grown by pile pulling 26 17 with helix tube, several surface holes 23 have been cut on every joint sleeve pipe 17 surfaces, every joint sleeve pipe 17 joint areas steel plate 27 of putting more energy into of burn-oning, sleeve pipe 17 diameters surpass by pile pulling 26 diameters, as the time being caused hole enlargement in construction, then need select much larger than by the sleeve pipe in 26 footpaths of pile pulling (17) by pile pulling 26;
4. at sleeve pipe 17 outside four qi of chong channel ascending adversely pipes 12 and four jet water spouts 13 arranged, wherein each is one group with a qi of chong channel ascending adversely pipe 12 and a jet water spout 13, and outside coated with protective sleeve 11, protective sleeve 11 is symmetrically distributed in sleeve pipe 17 outside one-tenth cruciform shape; Four qi of chong channel ascending adversely pipes 12 at four protective sleeve 11 tops are connected with jet water spout 13 with four qi of chong channel ascending adversely pipes 12 of outside respectively by hollow bolt with jet water spout 13, are connected with air compressor machine 10, storage tank 7 respectively by air compressor machine four-way connection 29, storage tank four-way connection 28 then;
5. be close to the bottommost of protective sleeve 11, four the coaxial injection apparatus 25 of gas-vapor mix of burn-oning respectively in sleeve pipe 17 outsides, wherein the end face of the coaxial injection apparatus 25 of gas-vapor mix by hollow bolt respectively with protective sleeve 11 in qi of chong channel ascending adversely pipe 12, jet water spout 13 couple together, three water under high pressure air-flow spouts 32 on the medial surface of the coaxial injection apparatus 25 of gas-vapor mix then dock with three apertures on the sleeve pipe 17;
6. couple together with sleeve pipe 17 at the bottommost of sleeve pipe 17 protection ring 24 of burn-oning, and by the steel plate 27 of putting more energy into;
7. select vibrating hammer 14, by vibrating hammer clamp 15 cannula system and vibrator sunk pile machine system are coupled together, open control cabinet 20, hang cannula system extremely by pile pulling 26 pile crowns with hoist engine 21, adjust hoist engine 21, guarantee sleeve pipe 17 center lines with by pile pulling 26 center lines on same straight line;
8. open control cabinet 20, start vibrating hammer 14, the resistance of the exciting force of guaranteeing vibrating hammer 14 during greater than sinking sleeve (17) down sinks sleeve pipe 17;
9. be sink in protection ring 24 bottoms from being begun to open air compressor machine 10 and high-pressure pump 6 at the bottom of 26 of the pile pullings at 1/3 o'clock, spraying 12 strands of water under high pressure air-flows 33 by the spout 32 in four coaxial injection apparatus 25 of gas-vapor mix in sleeve pipe 17 carries out while the operation of descending sinking sleeve 17, spraying water under high pressure air-flow 33, until following sinking sleeve 17 to by the position at the bottom of 26 of the pile pullings, resistance is bigger during following sinking sleeve 17, can promote sleeve pipe 17,3-4m, descend sinking sleeve 17 again, the resistance that repeats when descending sinking sleeve 17 is very little, the resistance in the time of also can reducing pile pulling;
10. open control cabinet 20, extract sleeve pipe 17 with hoist engine 21 after, move on another velamen pile pulling 26 pile crowns or the ground;
On by pile pulling 26 pile crowns, will be extracted steel wire loop by pile pulling 26 with crane 31.
The utility model extractor has following characteristics:
Adopt the utility model, reduced by pile pulling and the resistance between the soil on every side, handle is not pulled off by pile pulling in the time of not only can not having caused pulling out, and makes extensive pile pulling become possibility.
