Steel wire brush drill rotor rotor rotor and solve the method of buried drills, drilling, and stuck drills

Abstract

The invention belongs to the technical fields of basic engineering such as transportation, municipal administration, water conservancy, and construction. A wire brush drill bit rotary drilling rig and a method for solving buried drills, dropped drills, and stuck drills, including auxiliary walking and transportation equipment, a drill frame, a rotary well frame, a power mechanism, a hollow drill pipe, and a wire brush drill bit. The brush drill bit includes a solid drill rod and wire brushes fixedly distributed on the solid drill rod. The wire brush includes a wire brush body fixedly connected with the solid drill rod and steel wires embedded in the wire brush body. According to the drilling depth, the wear, deformation and bending of the wire brush drill bit during the drilling process, the present invention can effectively analyze and draw the offset and reverse direction of the drill bit accurately, which is convenient for lifting and fishing, and greatly improves the overall The salvage efficiency greatly reduces the difficulty of salvage, and can be applied to the occurrence of various accident situations, which has good promotional significance.

Description

technical field [0001] The invention belongs to the technical fields of basic engineering such as transportation, municipal administration, water conservancy, construction, etc., and specifically relates to a rotary drilling rig with a wire brush drill bit and a method for solving buried drill, dropped drill and stuck drill. Background technique [0002] Foundation piles are widely used as the foundation of buildings, especially in building structures such as bridges and houses. They are famous for their high quality, low price, flexibility, simplicity, and strong adaptability. As a foundation project, foundation piles have many hole-forming methods, mainly including drilling, punching, and rotary digging. The choice of hole-forming scheme directly determines the effectiveness of engineering construction, and how to choose a good hole-forming scheme for foundation piles must consider the geological conditions at the bridge site. [0003] However, no matter what construction...

Problems solved by technology

At that time, an 85-ton crane was first used, which not only could not be lifted, but almost caused the crane to overturn; later, two 20-ton hoists were used to pull at the same time, but failed; and then four 200-ton jacks were used to borrow steel bracket When it was jacked up, the 45# I-beam was deformed, and the steel wire rope was broken for a few wires and did not move, only a huge ear-piercing sound!

[0007] (2) At that time, the rotary drilling rig was installed again for pump suction reverse circulation slurry change and hole cleaning, trying to reduce the mud specific gravity, reduce the sediment deposited on the drill bit and its adsorption force, but to no avail!

[0009] (4) The underwater blasting plan was drawn up, but it was not sure how to deliver the explosives, etc., and it also failed
