Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a clear away drill bit soon of useless stake, includes and bores a section of thick bamboo 1, the bottom of boring a section of thick bamboo 1 is equipped with the opening, and the opening part is equipped with bottom cutter 3, and bottom cutter 3 detachable sets up on boring a bottom opening of section of thick bamboo 1 to in select specific cutter according to different geological conditions, and change when bottom cutter 3 seriously loses. The opening at the bottom of the drilling cylinder 1 is covered at the upper end of the waste pile, and the soil around the drilling cylinder is drilled through the bottom cutter 3, so that the preparation before cutting is realized. The top of the inner cavity of the drill barrel 1 is provided with a top drill bit 6, and the bottom of the inner cavity of the drill barrel 1 is provided with a bottom drill bit 5. The top drill bit 6 and the bottom drill bit 5 are arranged in the direction opposite to the drilling direction of the drill barrel 1 and are used for cutting and reaming the waste pile entering the drill barrel 1. The top 6 and bottom 5 cutters may be triangular ribs, so that the pile head in the drill barrel 1 is completely broken when the drill bit is twisted.
The top of the drilling barrel 1 is provided with a drill rod joint 2 used for installing the drilling barrel 1 at the lower end of a drill rod of the rotary drilling rig, so that the whole drilling barrel 1 is driven to drill.
The top and the lateral wall of the drill barrel 1 are both provided with an exhaust and slurry discharge hole 4, gas and slurry can be discharged into or out of the drill barrel 1 through the exhaust and slurry discharge hole 4 in the process of lowering and lifting the drill bit, and in addition, the waste pile 8 in the drill barrel 1 can be cleaned up to ensure smooth construction.
The outer side wall of the drill cylinder 1 is provided with the protective ribs 7 and the spiral strips, so that abrasion to the drill cylinder 1 in the drilling process is reduced, and the integral strength of the drill cylinder 1 is guaranteed.
The working principle is as follows: in the preparation work, the rotary drilling bit is firstly installed at the lower end of a drill rod of the rotary drilling rig through a drill rod joint 2, and the size of the selected drill bit is selected to ensure that the inner diameter of a drilling barrel 1 of the drill bit is slightly larger than the diameter of the waste pile to be cleaned. And then, the equipment is shifted to a target pile position, and the drill bit and the drill rod are vertically erected on the target pile position. After the target pile position is confirmed, the rotary drilling rig is controlled to lower and rotate the follow-up drill rod, and the rotary drilling bit tool cuts the target waste pile out of soil by means of the huge torque and the downward pressure of the rotary drilling rig.
The rotary drilling bit continuously rotates and falls until the pile head penetrates into the top of the drilling cylinder 1 of the drilling bit, and the top reamer 6 and the bottom reamer 5 are used for reaming the waste pile. If the continuous rotation cannot smoothly hinge the waste pile, the rotary drilling bit is rotated repeatedly in the forward direction or the reverse direction, so that the top reamer 6 and the bottom reamer 5 are twisted into the target waste pile, the reinforced concrete is completely hinged and broken, and the waste pile cutting is completed. The bottom reamer 5 can keep the broken waste pile inside the drilling barrel 1, the waste pile is lifted upwards to the ground along with the drilling barrel 1, the rotary vibration rotary drilling bit is repeatedly rotated to enable the waste pile to fall off from the drilling barrel 1, and a part of waste pile removal is completed. And (5) shifting the drilling machine to the position of the waste pile, and repeating the process to complete the removal of all the waste piles.
The utility model discloses still provide another kind of technical scheme: the top 6 and bottom 5 drill bits are cutting tools, the remaining features being unchanged.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
