Foot-operated formula three position four-way directional control valve a61 also exports direction for controlling the fluid power of rotary motor a14, and the 2nd equilibrium valve a9 ground arranges time position phenomenon being possible to prevent to turn round after putting in place.
Foot-operated formula three position four-way directional control valve a61 ground is selected, being convenient to officer operate in wheel house 15, convenient control, relatively electromagnetic type reversing valve is low for its cost simultaneously, can also using electromagnetic type reversing valve in practice, it is identical with the foot-operated formula three position four-way directional control valve a61 essence in the present embodiment.
The oil outlet of described oil pump a2 is connected with fuel-displaced tensimeter a4 by oil pipe, and described oil return filter core a11 is connected with oil return tensimeter a16 by pipeline, and the pipeline that the oil-in of described oil pump a2 is connected with fuel tank a1 is provided with ball valve 17.
The spiral rig of the present embodiment is in use, first should be in place, subsequently location work is carried out in the place needing boring, then fuselage 1 is driven to turn round by traversing mechanism 7, and the translational movement of fuselage 1, drilling rod 5 is moved to predetermined position by these two kinds of actions, and namely the long ship oil cylinder a13 and rotary motor a14 in hydraulic efficiency system enters working order, stops work after adjusting to the right place. Then starting unit head 4, unit head 4 rotates gear reducing motor usually as propulsion source, drives the rotary motion of drilling rod 5. And hydraulic control system so that hoist motor a18 enters working order, drives pressurization winch 8 to provide power to the axial action of drilling rod 5. Simultaneously after creeping into, when drilling rod 5 gos up, drilling rod 5 and drill bit 51 are cleared up by the blade 661 on Scraping device, after cleaning out.Can again enter above-mentioned workflow, until operation is complete.
When holing, it is also possible to follow following technique. Long-spiral drilling machine is in place → and boring (according to whether geological condition pressurizes) → get into clears up → pulls out at the bottom of the design degree of depth → hole and bore concrete perfusion → shifting drilling machine → put Steel Reinforcement Cage → vibration → pile simultaneously.
Long-spiral drilling machine is in place: when long-spiral drilling machine is in place, it is necessary to held stationary, do not tilt, displacement, for accurately controlling drilling depth, or should make the scale of control in frame on machine pipe, so as to carry out observing in construction, record.
Boring: straightening column 3, to good stake position (using contraposition circle), machine creep into, be unearthed, according to geological condition open pressurization system. Stop boring after reaching the design degree of depth.
Hole subsoil cleaning. After getting into the predetermined degree of depth, it is necessary to carry out dallying soil clearly in bottom, hole, then stops rotating; Carry drilling rod 5, drilling rod 5 must not be turned by song. Enter in drill-through journey the soil being scattered on ground, it is necessary to remove at any time and transport.
Winter, Pluvial construction:
(1) teletostage is when temperature is lower than less than 0 DEG C casting concrete, should take heating and thermal insulation measure. When building, concrete temperature is executed scheme regulation by the winter and is performed. Must not endure cold before stake top does not reach design strength 50%. When temperature is higher than 30 DEG C, according to particular case, concrete should be taked slow setting measure.
(2) Pluvial strict adherence is with boring the regulation with casting concrete, in case chance rain Cheng Konghou pours water causes collapse hole. Rainy day can not carry out drilling construction. The on-the-spot various measures that must have draining, prevent the surface water from flowing in groove, in order to avoid causing slope collapse or base soil depression, drilling machine inclination etc.
The above embodiment of the present invention is only the use that technical solution of the present invention is described simultaneously, is only enumerating of technical solution of the present invention, is not limited to technical scheme and the protection domain thereof of the present invention. Adopt equivalent technologies means, equivalent apparatus etc. that the improvement of the technical scheme disclosed in claims of the present invention and specification sheets is considered to be the scope not exceeded disclosed in claims of the present invention and specification sheets.
