Description

Technical Field

[0001] The present invention relates to the technical field of geotechnical engineering, and in particular to a supporting and protecting device for geotechnical engineering construction. Background Art

[0002] All kinds of projects on the ground, underground and in water are collectively referred to as civil engineering. The part of civil engineering involving rock, soil, underground and water is called geotechnical engineering. During the construction process, it is generally necessary to support and protect the inner wall of the construction to avoid construction accidents.

[0003] In the existing technology, when the common support and protection devices for geotechnical engineering construction are in use, most of the equipment are not extensible when supporting and protecting the vertical surface of the construction, resulting in a small support and protection range of the equipment. In addition, most of the existing equipment cannot be spliced between multiple devices when in use, and the equipment is not convenient to transport. Summary of the Invention

[0004] The purpose of the present invention is to provide a support and protection device for geotechnical engineering construction, which solves the above-mentioned technical problems.

[0006] Preferably, a T-shaped plug-in block 1 and a T-shaped plug-in block 2 are fixedly installed on the end of the baffle, and the T-shaped plug-in block 1 and the T-shaped plug-in block 2 are respectively slidably plugged into the inner wall of the T-shaped socket.

[0007] The cam is fixedly mounted on the inner wall of the sliding door, and the sliding door is fixedly mounted on the inner wall of the sliding door, and the sliding door is fixedly mounted on the outer wall of the sliding door.

[0008] Preferably, the mounting head is arranged in a symmetrical structure with the rotating shaft as the center.

[0009] Preferably, a T-shaped slot is formed in the end of the bottom plate, a T-shaped bar is inserted into the inner wall of the T-shaped slot, and the T-shaped bar is fixedly installed on the bottom of the support plate.

[0010] Preferably, a lower support hole is recessed into the side wall of the bottom plate, and an upper support hole is recessed into the side wall of the support plate. A support rod is installed between the lower support hole and the upper support hole, and support blocks are fixedly installed at both ends of the support rod. The two support blocks are respectively inserted into the inner walls of the lower support hole and the upper support hole.

[0011] Preferably, the base plate and the support plate are rotatably connected via a hinge rod.

[0012] Compared with related technologies, the support and protection device for geotechnical engineering construction provided by the present invention has the following beneficial effects:

[0013] The present invention provides a support and protection device for geotechnical engineering construction, which realizes support and protection of the rock wall by the support plate by assembling the bottom plate and the support plate and nailing the nails into the ground, and connects the plug one and the socket one and the socket two and the plug two on the side wall of the other bottom plate to each other, thereby realizing the splicing of the two bottom plates, thereby increasing the number of support plates according to the length of the rock wall, realizing support and protection for rock walls of different lengths, and installing a baffle on the top of the support plate to shield the upper end of the rock mass, effectively preventing the occurrence of rock blocks falling from the upper end of the rock wall and injuring workers.

[0014] The present invention provides a support and protection device for geotechnical engineering construction. The handle is rotated to drive the second bevel gear to rotate through the rotating shaft, and the meshing of the second bevel gear and the first bevel gear drives the screw to rotate. The sliding of the slider on the inner wall of the slide groove plays a limiting role, so that the installation head slides on the inner wall of the installation groove. When the installation head slides out from the surface of the stop block and inserts into the inner wall of the installation groove, the support plate is stably installed on the inner wall of the observation port, and the rock wall is supported by the support plate and the stop block together. When the installation head slides and shrinks from the inner wall of the installation groove to the inside of the storage cavity, the stop block can be taken out from the inside of the observation port, so that the staff can observe the condition of the rock wall through the observation port, so that the staff can adjust the construction plan according to the condition of the rock wall.

[0026] A T-shaped plug-in block 1 41 and a T-shaped plug-in block 2 42 are fixedly installed at the end of the baffle 4. The T-shaped plug-in block 1 41 and the T-shaped plug-in block 2 42 are respectively slidably plugged into the inner wall of the T-shaped socket 33;

[0027] When the T-shaped plug 1 41 is inserted into the inner wall of the T-shaped socket 33, the baffle 4 and the support plate 19 remain in a vertical state, thereby effectively shielding and protecting the top of the rock mass to prevent gravel from falling. When the T-shaped plug 2 42 is inserted into the inner wall of the T-shaped socket 33, the baffle 4 and the support plate 19 remain in a parallel state, thereby effectively reducing space occupancy and effectively increasing construction space.

[0028] The support plate 19 is provided with an observation port 32 on the surface of the support plate 19, and a mounting groove 35 is formed in the inner wall of the observation port 32.
