Abstract
The invention is a kind of half pore-forming and half-spiral drill rocker and the pore forming method, it refers to a kind of drill rocker for rock and soil engineering drill machine. The drill rocker is made up of non-spiral part, spiral part and drill head which has a material outlet. The drill rocker and the drill head are hollow. When using the drill rocker to carry on pore-forming, it is connected to the long spiral drill machine power mechanism, the head drills in downwards. The lower part of the drill head drills into the soil, the spiral pole guides the soil to the upper part, the soil is in free state after being guided to the upper part, it will not rotate with the drill rocker, friction between the soil and the smooth part of non-spiral part is small, it reduces the power consumption, and it can reduces the soil discharging quantity. When pulling out the drill rocker, the soil on it is squeezed to around. The invention has a low power consumption, and high efficiency.
Description
Technical field the present invention relates to a kind of drilling rod used on the geotechnical engineering rig that is used for, particularly a kind of drilling rod that can be used for substituting long spiral dry pore-forming pressure filling technology.
The drilling rod that the existing long-spiral drilling machine of background technology adopts is a long screw drill rod, all is arranged with blade from top to bottom continuously, can carry out dried pore-forming operation, also can be used for the pressure filling technology that hollow is done carrier pipe, the discharging of drill bit valve.The long screw drill rod of this continuous blade because of it needs than high pulling torque, then must be equipped with big power in creeping into soil the time, and the amount of being unearthed is big, especially in southern soft clay area, measures big because of being unearthed, not only remove soil compaction expense height, and very easily cause the ground filling, so become a harm greatly.Existing short thread segments drilling rod, the spiral number that auger stem section 2 is arranged is 2-3, generally is no more than 5, it is mainly used in wet pore-forming operation, needs the special mud of making during its operation, is with drilling mud practice, and environment is polluted.
Summary of the invention the objective of the invention is at above-mentioned deficiency, aims to provide the dried pore-forming semi-spiral drilling rod that a kind of energy consumption is low, casting is few, efficient is high.
The implementation of the object of the invention is, dried pore-forming semi-spiral drilling rod, by drilling rod and under the drill bit 1 of band discharging opening constitute.Drilling rod, drill bit hollow.Drilling rod top is no auger stem section 3, and the bottom is for there being auger stem section 2.
Hole forming method with dried pore-forming semi-spiral drilling rod, drilling rod is connected with the long screw auger mechanism of ocean, drill bit 1 creeps into downwards, drilling rod bottom drill bit incision soil layer, spiral section does not have spiral section with the soil top of leading, and wants the degree of depth until being drilled into, and upwards carries brill, soil of being taken out of by spiral section and top do not have around the part of loosening the soil around the spiral section is pressed against, and form boring.
Drilling rod of the present invention is by drill bit 1, by continuous helical section 2 with do not have spiral section 3 drilling rods three parts and form, drilling rod and drill bit hollow, and as the transport flow material conduit, the valve that drill bit is provided with is a discharging opening, and soil, water enter in the drilling rod in the time of also can preventing to creep into.When using the boring of this drilling rod, drilling rod is connected with the long screw auger mechanism of ocean, drill bit creeps into downwards.When creeping into, because drilling rod bottom drill bit incision soil layer, spiral section is with the soil top of leading, after can realizing creeping into the no spiral section of regolith importing, free state, no longer rotate with drilling tool and move, smooth no spiral section drilling-rod external wall is very limited to power consumption with the frictional force that soil forms, and disappears thereby can reduce power.Soil is not all derived yet simultaneously, can significantly reduce the casting amount.Carry when boring, the part spiral of drilling rod bottom can guarantee to form a stake hole, reaches the purpose of dried pore-forming, and soil of being taken out of by spiral section and top do not have around spiral section loosening the soil on every side partly be pressed against, and pile hole forming is good.
Adopt drilling rod of the present invention and hole forming method, the soil body motion of spiral section is only arranged, more about 30% than there being conventional long-spiral drilling machine to reduce power, energy consumption is low; Long screw drill rod can reduce casting amount 50～90%, thereby avoid a large amount of castings to clear work relatively continuously, has the excellent economy and the value of environmental protection; Rate of penetration than conventional long-spiral drilling machine doubles, the efficient height, and when especially creeping in weak soil, its efficient is higher.
Description of drawings
The caliber that Fig. 1 the present invention does not have a spiral section drilling rod hollow tube equals to have the caliber structural representation of spiral section hollow tube
Fig. 2 the present invention does not have the external diameter of spiral section drilling rod hollow tube greater than the external diameter structural representation that the spiral section hollow tube is arranged
Also has the actuating unit that constitutes by adpting flange 4, reducer 5, motor 6 etc. among the figure.
The specific embodiment
Drilling rod of the present invention is by drill bit 1, by continuous helical section 2 with do not have spiral section 3 three parts and form, drilling rod and drill bit hollow, and as the transport flow material conduit, the valve that drill bit is provided with also is a discharging opening.
Drilling rod of the present invention has the spiral number of auger stem section 2 to be no less than 5.Have the auger stem section changeable, be 2-5m, its length is no more than half of embedded depth usually.In the darker soil of weak weak soil layer, it is good with 3～5m spiral section being arranged, mould firmly with hard soil layer and layer of sand in, be good with 2～3m.Drill bit 1 can have dark fishing tail drill bit usually, also can select the drill bit that has blade row for use, is equipped with according to the soil layer situation, and the external diameter of the no spiral section drilling rod hollow tube 〉=external diameter of spiral section hollow tube is arranged only need satisfy the requirement of hollow continuous.
During boring, drill bit 1 creeps into downwards, drilling rod bottom drill bit incision soil layer, spiral section does not have spiral section with the soil top of leading, and wants the degree of depth until being drilled into, and upwards carries brill, soil of being taken out of by spiral section and top do not have around the part of loosening the soil around the spiral section is pressed against, and form boring.
