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

Embodiment 1

[0040] Embodiment one: see Figure 1-Figure 4 , a wire brush drill bit rotary drilling rig according to the present invention, comprising auxiliary walking and transportation equipment 1, a power mechanism 4 is arranged on the auxiliary walking and transportation equipment 1, a drill frame 2 is arranged corresponding to the well hole, a rotary Well frame 3, hollow drill pipe 5 and wire brush drill bit 6, described auxiliary walking and transportation equipment 1 is automobile or power tricycle, and described wire brush drill bit length is 4m~6m, and described wire brush drill bit 6 includes Solid drill rod 7 and the steel wire brush 8 that is fixedly distributed on the solid drill rod 7, described steel wire brush 8 comprises the steel wire brush body 9 that is fixedly connected with solid drill rod 7 and the steel wire 10 that implants steel wire brush body 9, so The steel wire brush body 9 described above is a multi-strand twisted steel wire rope with a certain rigidity, and...

Embodiment 2

[0042] Embodiment two: see Figure 1-Figure 4 , a method for solving buried, dropped, and stuck drills using the wire brush drill bit rotary drilling rig described in Embodiment 1, for the situation of buried drills, dropped drills, or stuck drills in the drill bit of the drilling rig during the construction process, carry out the salvage of the drill bit Operation, first check the design drawings, find out the hydrogeological conditions, check the construction hole records, ask and investigate the operators, determine the cause of the accident and the corresponding depth of the drill bit, and carry out the following salvage steps:

[0043] ① Put the wire brush drill bit rotary drilling rig in place in the well hole, connect the drill pipe and the wire brush bit until it reaches the accident location, and then slowly drill in to observe the resistance, difficulty, and amount of footage received by the drilling rig, until until the footage cannot be continued;

[0044] ② Lift ...

Abstract

The invention belongs to the technical field of foundation engineering such as traffic engineering, municipal engineering, hydraulic engineering and building engineering and relates to a wire-brush-bit rotary drilling jig and a method for solving bit burying, falling and jamming. The wire-brush-bit rotary drilling jig comprises auxiliary travelling and transporting equipment, a drill stand, a rotary well template frame, a power mechanism, a hollow drill stem and a wire brush bit. The wire brush bit comprises a solid drill stem and a wire brush fixedly distributed on the solid drill stem. The wire brush comprises a wire brush body fixedly connected with the solid drill stem and wires embedded in the wire brush body. By aiming at drilling depth and abrasion, deformation and bending of the wire brush bit during a drilling process, deviation and reverse of the bit can be effectively analyzed and drawn precisely to facilitate lifting and fishing, overall fishing efficiency is greatly improved, fishing difficulty is greatly decreased, the drilling rig and the method are applicable to various different accidents and are of great popularization 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...
