Abstract
The invention discloses a three-layer rock-socketed tube drill of a rotary drilling rig, which comprises a flange, an inner layer of conical tubular drill body, a middle layer of conical tubular drill body and an outer layer of conical tubular drill body. The flange is arranged at the upper ends of the inner layer of conical tubular drill body, the middle layer of conical tubular drill body and the outer layer of conical tubular drill body, and the inner layer of conical tubular drill body, the middle layer of conical tubular drill body and the outer layer of conical tubular drill body are concentrically distributed; the length of the inner layer of conical tubular drill body is larger than that of the middle layer of conical tubular drill body and the outer layer of conical tubular drill body; the length of the middle layer of conical tubular drill body is equal to that of the outer layer of conical tubular drill body; the lower end of the inner layer of conical tubular drill body extends out of the middle layer of conical tubular drill body and the outer layer of conical tubular drill body; an outer wall of the outer layer of conical tubular drill body is provided with an inclined ridge; and bullet cutter teeth are uniformly distributed on a lower end edge of the inner layer of conical tubular drill body, a lower end edge of the middle layer of conical tubular drill body and a lower end edge of the outer layer of conical tubular drill body. The tube drill has the advantages of high working efficiency and is suitable for bedrock strata with higher hardness, large boulder layer and hard perennially frozen ground.
Description
Technical field
The present invention relates to a kind of rock tube and bore, especially relate to three layers of embedding rock of a kind of rotary drilling rig tube and bore.
Background technology
Rotary drilling rig is the construction machinery of pore-forming operation in a kind of suitable building foundation engineering.It is a kind of more special drill bit that the used rock tube of rotary drilling rig bores, and major advantage is that drilling depth is very fast.For the bigger basement rock stratum of hardness, big erratic boulder layer and hard permafrost, need to go out annular groove by the drilling of rock tube earlier, cooperate augers again or revolve and dig drill bit and just can creep into, directly use short augers or revolve and dig drill bit and hole, just difficulty relatively.The cutting element that the rock tube bores can be divided into bucket tooth, pick, is applicable to soft rock and middle hard rock respectively.The main effect that the rock tube bores is to empty becoming flexible around the core in the hole, for the follow-up broken core of the short augers of embedding rock that is lowered to is created the broken scope of freedom.
But for the soil layer of some geologic structure complexity, as the frozen soil problem of Qinghai-Tibet Platean, big erratic boulder layer and competent bed etc., existing rock tube bores and lacks enough drilling abilities, and operating efficiency is lower.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the invention provides a kind of high efficiency, drilling ability is strong, is applicable to that the bigger basement rock stratum of hardness, big erratic boulder layer and three layers of embedding rock of rotary drilling rig tube of hard permafrost boring bore.
Technical scheme of the present invention is: it comprises flange, also comprise nexine cone barrel drill body, intermediate layer cone barrel drill body and outer cylindrical shape drill body, described flange is located at nexine cone barrel drill body, intermediate layer cone barrel drill body, outer cylindrical shape drill body upper end, described nexine cone barrel drill body, intermediate layer cone barrel drill body and outer cylindrical shape drill body distribute with one heart, nexine cone barrel drill body length is greater than intermediate layer cone barrel drill body, outer cylindrical shape drill body length, intermediate layer cone barrel drill body length and outer cylindrical shape drill body equal in length, intermediate layer cone barrel drill body is stretched out in nexine cone barrel drill body lower end, outside the outer cylindrical shape drill body, outer cylindrical shape drill body outer wall is provided with slanting, described nexine cone barrel drill body lower edge, intermediate layer cone barrel drill body lower edge, outer cylindrical shape drill body lower edge all is evenly distributed with the sub warhead pick.
Preferred two groups of the slanting of described outer cylindrical shape drill body outer wall, two groups of slantings are symmetrically distributed in outer cylindrical shape drill body outer wall, 5 of every group of slantings.
The cone angle of described nexine cone barrel drill body is preferably 30 ~ 45 °, and the cone angle of the cone angle of intermediate layer cone barrel drill body and nexine cone barrel drill body equates.
The interlaced arrangement of sub warhead pick of described nexine cone barrel drill body lower edge, intermediate layer cone barrel drill body lower edge, outer cylindrical shape drill body lower edge, adjacent sub warhead pick is mutually 30 ~ 45 °.
Use the present invention, revolve and dig when creeping into, because nexine cone barrel drill body length is greater than other two-layer drill body length, hometown layer cone barrel drill body contacts with soil layer earlier, owing to cone barrel face and sub warhead pick are certain angle, thereby helps reducing to creep into resistance.Along with going deep into of creeping into, intermediate layer cone barrel drill body begins to contact with soil layer with outer cylindrical drill body, creeps into area and progressively increases, and 3 layers of drill body wall also can bear bigger pressure, helps Spiral digging machine and carries bigger moment of torsion to drilling bucket, strengthens drilling ability.Outer cylindrical shape drill body helps guaranteeing the verticality and the drilling quality of holing.Along with the continuation of drill body is goed deep into, the slanting on the outer cylindrical shape drill body outer wall makes drill body creep into along the direction spiral of slanting, and more traditional vertical bar resistance is littler, and energy consumption is lower.Three layers of embedding rock of rotary drilling rig tube of the present invention bores, and is applicable to the bigger basement rock stratum of hardness, big erratic boulder layer and hard permafrost.
