Rotary drilling rig and bittern collecting method

Abstract

The invention discloses a rotary drilling rig and a bittern collecting method. The rotary drilling rid is provided with a torque transmission drill pipe and a drill bit, wherein the torque transmission drill pipe is connected with a power head of the rotary drilling rig and can transmit torque of the power heat, a slurry injection passage is arranged in the torque transmission drill pipe, and the drill bit is mounted at the bottom end of the torque transmission drill pipe. The slurry injection passage where slurry can be injected and discharged is arranged in the torque transmission drill pipe of the rotary drilling rig, and during hole forming, the slurry is injected into the slurry injection passage and can be discharged from the torque transmission drill pipe and can rise together with drill slags of the drill bit, and meanwhile, part of slurry can cover the hole wall and has a function of protection the hole wall. The rotary drilling rig has the advantages of high drilling efficiency, simple structure and capability of realizing deep-hole drilling. The bittern collecting method includes utilizing the rotary drilling rig to drill a permeable hole by the positive-circulating rotation drilling method and collecting bittern permeated into the permeable hole. By the bittern drilling method, deep-layer bittern can be extracted.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a rotary drilling rig and a method for collecting brine. Background technique [0002] Rotary drilling rig is a construction machine for taking soil and forming holes for cast-in-place piles. It has the advantages of stable power transmission and high efficiency. It is widely used in various foundation constructions such as cast-in-place piles, continuous walls, and foundation reinforcement. The rotary drilling rig is mainly composed of a chassis and a working device. The chassis includes a traveling mechanism, an underframe and a car slewing system. Working devices usually include luffing mechanism, mast assembly, main winch, auxiliary winch, power head, drill pipe and drilling tools, etc. [0003] The process of drilling a hole with a rotary drilling rig is roughly as follows: through the traveling mechanism of the drilling rig and the mast luffing mechanism, the drilling ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the existing rotary drilling rigs are: during the drilling process, the drilling tool needs to be frequently lifted out to unload the soil, the operation is cumbersome, and the drilling efficiency is low

In some areas of our country, such as Qinghai, the depth of brine is generally above 100 meters, but limited by the drilling depth of existing rotary drilling rigs, only the brine at tens of meters underground can be collected, and for deeper brine Unable to collect, resulting in a waste of resources
