Embodiment 1

[0025] see Figure 1~4 , in an embodiment of the present invention, a drilling device for geotechnical engineering investigation includes a fixed frame body, a drill rod 8 and a lifting mechanism for driving the drill bit to drill, and the fixed frame body is composed of three supporting vertical rods 1 in a triangular distribution. It consists of a side connecting rod 2 for connecting and fixing three support vertical rods 1 to each other. The upper side of the side connecting rod 2 is provided with a fixed platform 5 and a mounting frame 6. The lifting mechanism includes a screw rod 7 and a drilling motor 14 , the fixed platen 5 is installed on the fixed frame body, the mounting frame 6 is fixed on the fixed platen 5, the central part of the fixed platen 5 is provided with a screw hole 26, and the screw rod 7 passes through the screw hole 26 and is screwed with it, The top of the screw mandrel 7 is fixed with a driving vertical rod 28 in the same direction, and the outer sid...

Embodiment 2

[0030] The difference between this embodiment of the present invention and Embodiment 1 is that: each side connecting rod 2 is provided with a connecting socket 9 on the rod wall, and the fixed platen 5 has a triangular structure and each side of the fixed platen 5 The sides are fixed with convex plates 12 corresponding to the three inserting rods 3, and the bottom of the convex plates 12 is fixed to be inserted into the connection socket 9 and fixed by fastening nuts 11. Since the triangle can increase the firmness, the device is stable. Strong and the drilling parts are detachable from the holder body for easy use.

Abstract

The invention discloses a drilling device for geotechnical engineering investigation, relates to the technical field of geotechnical construction, and mainly aims to solve the problem that the depth of drilling rock and soil is not prone to being controlled. The drilling device comprises a fixing frame, a drill pipe and a lifting mechanism for driving a drill bit to drill, the fixing frame is composed of three supporting vertical rods in triangular distribution and side connecting rods allowing the three supporting vertical rods to be connected and fixed to one another, a fixing table plate and an installation frame are arranged on the upper sides of the side connecting rods, the lifting mechanism comprises a screw and a drilling motor, an adjusting screw is further arranged on the installation frame, an installation plate is arranged on the adjusting screw, a pressure sensor is arranged at the upper end of the installation plate, a pressing plate is arranged on the bottom wall of theadjusting screw, and the edge side of the installation plate is slidably connected to the rod wall of the installation frame. According to the drilling device for geotechnical engineering investigation, the structure is simple, stable and firm, the drilling depth can be adjusted and accurately controlled, the simpleness, convenience and rapidness are achieved, disassembly can be achieved, carryingis convenient, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of geotechnical construction, in particular to a drilling device for geotechnical engineering investigation. Background technique [0002] Drilling or prospecting is the use of deep drilling mechanical engineering technology to mine underground or seabed natural resources, or to take real-time stratum sections and take physical samples to provide experiments to obtain relevant data, etc. Drilling methods are basically auger method, flushing method, percussion method, rotary method, core method, no core method, rotary percussion method, hand drill, rotary vane drill, water punch drill and clay cutting pipe and so on. According to different terrains, environments and actual conditions, through detailed planning such as observation and evaluation, coupled with judgment and limitations (including human resources and equipment, etc.), decide which drilling method to adopt; [0003] And many drilling devices that...
