The utility model is characterized in that the horizontal hole drilling device also comprises a hole expanding machine, a reduction joint and a guide machine, wherein the hole expanding machine is arranged between the drilling head and the rock core pipe; the outer diameter of the hole expanding machine is the same as the outer diameter of the drilling head, and the surface of the hole expanding machine is provided with a cutting edge; the back end of the rock core pipe is connected with the reduction joint which is connected with the drilling rod, and the guide machine is sheathed on the drilling rod; the reduction joint and the surface of the guide machine are provided with grooves along an axial direction, and the outer diameter of the guide machine is the same as the outer diameter of the drilling head. The utility model can improve the straightness and the horizontal accuracy of a horizontal hole with a wide span.
Description
(1) technical field
The utility model relates to the concrete foundation high-precision horizontal drilling device that carries out high-precision horizontal drilling on bases such as concrete.
(2) background technology
At present, diamond rope saw cutting is one of advanced construction technology such as the maintenance, transformation, dismounting etc. of building etc.The diamond rope saw cutting must get out pilot hole.Boring for high accuracy, the horizontal pilot hole of large span, adopt common drilling tool in the level that reaches tens of meters is crept into, because the gravity sag of drilling tool in the boring annular gap, boring produces unmanageable straight line precision and horizontal direction changes, the skew of horizontal pilot hole causes the distortion of cutting section, so that follow-up construction and dyscalculia, needization expense plenty of time and energy are repaired, and cause construction period to prolong.Therefore the high-precision horizontal drilling device is the key that gets out pilot hole.The Japan Patent spy opens 2000-59109 and Te Kai 2000-87677 discloses a kind of high-precision horizontal drilling device.
(3) summary of the invention
The purpose of this utility model is to provide a kind of concrete foundation high-precision horizontal drilling device, and this drilling equipment can improve large span lateral aperture glacing flatness and horizontal accuracy.
The utility model is achieved in that a kind of concrete foundation high-precision horizontal drilling device, comprise drill bit, basket, drilling rod, drilling rod connects the drive unit output shaft, it is characterized in that described horizontal drilling device also comprises reamer, reducer union, guider, between drill bit and basket, reamer is housed, the reamer external diameter is identical with outside diameter, the reamer surface has cutting edge, termination reducer union behind the basket, the reducer union stacks, guider is sleeved on the drilling rod, and reducer union and guider surface have groove vertically, and the guider external diameter is identical with outside diameter.
Above-mentioned concrete foundation high-precision horizontal drilling device, described guider is fixedly connected on the drilling rod by screw thread; Perhaps guider embeds to be connected on the drilling rod and also can rotate around drilling rod.
Above-mentioned concrete foundation high-precision horizontal drilling device, described guider surface is made by high-abrasive material.
The utility model guarantees that by install guider additional on drilling tool drill bit creeps into along the design axis direction.Guider generally must be equipped with in per 3 meters on drilling rod and be no less than 1, to realize the high accuracy correcting of full hole.The utility model can improve large span lateral aperture glacing flatness and horizontal accuracy.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model concrete foundation high-precision horizontal drilling apparatus structure schematic diagram;
Fig. 2 is guider and drilling rod connection diagram.
Among the figure: 1 drill bit, 2 reamers, 3 baskets, 4 reducer unions, 5 drilling rods, 6 guiders, 7 guider external surfaces.
(5) specific embodiment
Referring to Fig. 1, Fig. 2, a kind of concrete foundation high-precision horizontal drilling device comprises drill bit 1, basket 3, drilling rod 5, reamer 2, reducer union 4, guider 6.Drill bit 1 is made according to concrete strength, and drill bit 1 is a diamond bit, has sharp, high accuracy, high drilling speed characteristic.At drill bit 1 and 3 of baskets reamer 2 is housed, reamer 2 external diameters are identical with drill bit 1 external diameter, and reamer 2 surfaces have cutting edge, and reamer 2 guarantees that the guider 6 on the follow-up drilling rod 5 can enter in the boring.Basket 3 adopts the high-strength light material to make, basket 3 back termination reducer unions 4.Reducer union 4 stacks 5, guider 6 is sleeved on the drilling rod 5, drilling rod 5 external Pump keeper for undergroud drilling, drilling rod 5 external drive unit output shafts drive drilling rod 5 rotations by drive unit, thereby drill bit 1 are pushed ahead.Reducer union 4 and guider 6 surfaces have groove vertically, and this groove is a tank, and external Pump keeper for undergroud drilling is sent into water in the boring drill bit 1 is cooled off.Guider 6 external diameters are identical with drill bit 1 external diameter, creep into along the design axis direction to guarantee drill bit 1.Guider 6 can be fixedly connected on the drilling rod 5, referring to Fig. 2 by screw thread; Or guider 6 embedded be connected on the drilling rod 5 and can move ahead with drilling rod 5 around drilling rod 5 rotations.Guider external surface 7 is made by high-abrasive material, and high-abrasive material is the W-Co cermet, makes guider external surface 7 be difficult for being worn and torn by concrete foundation, thereby influences borehole accuracy.Must be equipped with in per 3 meters on the general drilling rod 5 and be no less than 1 guider 6, to realize the high accuracy correcting of full hole.
Claims (4)
