The present disclosure relates to the technical field of geotechnical engineering. An embodiment of the present disclosure provides a geotechnical engineering drilling device, including a base platform. A support is fixedly installed on the top of the base platform. A moving plate is movably installed inside the support. A first motor is fixedly installed on the top of the moving plate. A drill pipe is rotatably installed at the bottom of the moving plate. In the present utility model, through the rotation of the rotating plate, the reinforcement pile is drilled into the soil. Then, through the rotation of the rotating rod, the casing is displaced downward. The downward displacement of the casing will squeeze the reinforcement block into the soil through the slope surface of the reinforcement block, completing secondary reinforcement. Compared with traditional devices, this device can fix the base platform through the reinforcement pile and can also increase the contact area between the reinforcement pile and the soil through four groups of reinforcement blocks. Through the above technical solution, the technical problems of poor fixing effect and easy deviation of the drill pipe in the prior art are solved.

This invention relates to the field of deep foundation pit support construction technology, specifically a recyclable sheet pile construction device and method for deep foundation pit support. It includes two sheet pile walls, with four cylinders installed at the center of each adjacent side of the two sheet pile walls. Two baffles are fixedly connected to the telescopic ends of the eight cylinders. Three limiting sleeves are symmetrically fixed to each adjacent side of the two baffles. Three support rods are inserted between the six limiting sleeves. This invention features a fully modular, plug-in assembly system, requiring no welding or cutting. It remains intact after dismantling and can be reused repeatedly, significantly reducing construction costs and construction waste. Synchronous control of multiple cylinders allows for real-time adjustment of the top support force based on the soil pressure in the foundation pit, adapting to different depths and soil conditions. The support stability is extremely strong. The limiting rods and through-hole guide structure ensure coaxial support of the baffles, preventing misalignment. The sleeves and support rods distribute force evenly, eliminating stress concentration and preventing pile tilting.

Advantageous effects: the utility model has adopted concave frame and mounting shaft, through setting concave frame and mounting shaft, possesses multiple cutting structure, can realize the multistage cutting of wood board fast, has improved the working efficiency of cutting device for wood board processing.

The invention discloses an engineering van rear protective fence assembly and a production detection device thereof, and relates to the technical field of engineering van rear protective fence production, the engineering van rear protective fence assembly comprises a rigidity detection assembly, the rigidity detection assembly comprises a control cylinder, a communicating pipe, an upper cavity, an upper piston, an abutting block, a lower cavity, a lower piston, a reset spring, an adjusting screw rod and a contact switch, the output end of the control air cylinder is fixedly connected with a communicating pipe. In the using process, the adjusting screw rod is in threaded connection with the tail end of the lower cavity, the distance between the contact switch and the lower piston is adjusted by rotating the adjusting screw rod, and then control over continuous force application of the air cylinder is stopped when the lower piston makes contact with the contact switch at the tail end of the adjusting screw rod; according to the invention, the swing arms at the two sides are both provided with the rigidity detection assemblies, so that rigidity testing can be synchronously carried out on the welding joints of the two ends of the rod piece and the wing plate, and the detection efficiency is improved.

The application discloses a micro switch and a car gauge level connector, and belongs to the electrical technical field, wherein the micro switch comprises a fixed seat, a movable seat, a driving part and a normally open contact component; at least two wiring terminals are arranged on the fixed seat; the movable seat is used for abutting against an external part and is movably arranged in the fixed seat through the driving part; and the normally open contact component is moved through the movable seat to complete closure and conduct each wiring terminal. The fixed seat can limit and guide the movable seat, thereby preventing the movable seat from shaking during movement, effectively avoiding deviation and dislocation of the normally open contact component during closure or opening, and enabling each contact to stably abut against each other, so that the reliability and stability of circuit conduction are remarkably improved. The application reduces the number of parts, simplifies the overall structure, is simple to assemble, saves time and labor, improves production efficiency, and is convenient for repair and maintenance.
