Embodiment 1

[0022] Embodiment one, refer to figure 1 , the bottom surface of the top plate 7 is welded with a jack 4, the jack 4 is provided with a lever plug 8, the piston rod 10 of the jack 4 runs through the second through hole 3 provided in the middle of the upper surface of the core tube 12 and extends to the inner cavity of the core tube 12 One end of the piston rod 10 located in the inner cavity of the coring tube 12 is welded with a top plate 11 , and the top plate 11 is slidably connected with the inner wall of the core tube 12 .

[0023] When the stem is stuck in the coring tube 12, the plunger can be inserted into the lever plug 8 to adjust the piston rod 10 of the jack 4, and the stem is pushed out by the cooperation of the piston rod 10 and the top plate 11, and the core When the head of the column is exposed to the outside of the core tube 12, the core column can be taken out by hand or clips, which is more convenient to use and improves the efficiency of coring. After the c...

Embodiment 2

[0024] Embodiment two, refer to figure 2 , the middle part of the upper surface of the coring tube 12 is provided with a threaded tube 16 communicating with its inner cavity, the threaded tube 16 is internally threaded with a threaded post 17, and the threaded post 17 is welded with a top plate 11 at one end of the inner cavity of the coring tube 12, and The top plate 11 is slidably connected with the core pipe 12 , the top end of the threaded column 17 is welded with a turning handle 14 , and one end of the turning handle 14 is covered with a sleeve 15 .

[0025] When the stem is stuck in the coring tube 12, the handle 14 can be turned to drive the top plate 11 to move down, so that the stem is ejected, which facilitates the separation of the stem and the coring tube 12. When the stem and the coring tube When the 12 cards were tighter, the sleeve pipe 15 could be placed on the rotary handle 14 to increase the arm of force, to achieve the purpose of labor saving, to facilitat...

Abstract

The invention discloses a core drill bit for road surface survey which is convenient for core removal, which comprises a core tube, the top of the side of the core tube is provided with a first through hole, and the bottom of the core tube is provided with a diamond cutter head. The bottom of the diamond cutter head is surrounded equidistantly with chip removal gaps. A bracket is installed on the outside of the top of the core tube. The top of the bracket is welded with a top plate. There are four mounting holes around equidistantly. The coring bit for pavement investigation which is convenient to remove the coring facilitates the detachment of the coring pipe and the core column, improves the coring efficiency, facilitates the survey work, and solves the problem of using the coring bit of the coring machine for coring. The core column is easily stuck in the coring tube, and it is very inconvenient to take it out, which brings some troubles to the coring work, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of surveying and surveying, in particular to a coring drill bit for road surface surveying which is convenient for removing cores. Background technique [0002] With the continuous development of social economy and the continuous improvement of people's living standards, people's travel is becoming more and more convenient, and many families have private cars; Therefore, the road management department is vigorously building roads. At present, most roads are made of asphalt pouring or cement masonry. After the road construction is completed, it is necessary to use a coring machine to conduct a core survey on the road to evaluate the porosity and thickness of the road. Currently, the quality evaluation of the road , but when utilizing the coring bit of the coring machine to take the core, the core column is easily stuck in the coring tube, and it is very inconvenient to take out, which brings certain troubles...
