Embodiment 1
[0025] from Figure 1-3 It can be seen that a method of processing percussion drilling into a hole buried in the present embodiment includes a linear drill bit 1 and a steel casing 5, and the steps are as follows;
[0026] Step 1: Take 3m long round steel, the lower end is cut into a pointed end to make a linear drill 1, the upper end of the linear drill 1 is equipped with a lock 3, the upper part of the lock 3 is provided with a reserved hole 4, and a steel wire rope is fixed in the reserved hole 4, which is convenient for hanging Starting linear drill 1;
[0027] Step 2: The whole body of the linear drill bit 1 is evenly and symmetrically welded with round steel 2, and there are four round steel 2, and the round steel 2.5m long, the end is cut into a sharp point, attached to the body of the linear drill 1 to improve the strength and weight of the linear drill 1;
[0028] Step 3: The bottom side of the linear drill bit 1 is the steel casing 5, and the end of the orifice ...

The invention discloses a method for treating impact drill hole forming and drill burying, and belongs to the technical field of drill burying treatment. A linear drill bit and a steel protection cylinder are included. The method comprises the steps that 1, a lock catch is arranged at the upper end of the linear drill bit; 2, round steel is evenly and symmetrically welded to the periphery of the linear drill bit; 3, positioning ribs are welded to the periphery of the end portion of the orifice steel protection cylinder; 4, a steel pipe is placed at the positions of any two positioning ribs, and the positioning ribs control the position of the steel pipe and prevent the steel pipe from moving; and 5, a steel wire rope of the linear drill bit goes down to the interior of a hole through the position of a pulley to break a soil layer. According to the method, the linear structure of the linear drill bit is utilized for breaking the soil layer on the upper portion, the middle portion and the lower portion of the notch position of the drill bit, then, broken soil is brought out through circulation mud, the drill bit can be conveniently fished out, and the slag removing efficiency in thehole is improved. According to the method, hole collapse earthwork in the hole can be effectively and rapidly treated, the drill bit is vertically through, the piston effect is avoided, and safety inthe drill bit fishing process is ensured.
Description
technical field [0001] The invention relates to the technical field of buried drill processing, and more specifically, relates to a method for processing buried drills formed by percussion drilling. Background technique [0002] The conventional treatment of buried drilling can be summarized into methods and steps such as "clearing, penetrating, topping, frying, expanding, fishing, smashing, digging". Buried drilling accidents often adopt the method of pulling the hard top, but it often fails to achieve results. The method of using linear drill bits to deal with percussion drilling and buried drilling can well solve the disadvantages caused by the above-mentioned conventional construction methods, effectively improve the construction efficiency and save costs. This operation method mainly uses the linear drill bit to break the earthwork at the upper and lower parts of the buried drill bit, and the broken soil is brought out by circulating mud, so that the buried drill bit c...
