[0002] Soft soil is a general term for a class of soils, including soft cohesive soil, silty soil, silt, peat soil, and peat. Soft soil is mainly composed of silt deposits with high water content, high compressibility, low bearing capacity, and a small amount of humus. It is characterized by high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor permeability, complex layered distribution, and large differences in physical and mechanical properties between layers.

[0003] Currently, in the construction of saturated soft loess foundation pit slopes, drilling equipment is required. However, when using this equipment, it is difficult to accurately control the drilling depth, easily leading to holes that are too deep or too shallow, affecting the installation effect of anchor bolts and the stability of the foundation pit slope.

[0026] This utility model provides a drilling device for anchor bolts on the slope of a saturated soft loess foundation pit. Please refer to [link / reference]. Figures 1-4The system includes a base 100 and an infrared ranging sensor 200. A fixed frame 110 is fixedly mounted on the top of the base 100. The inner wall of the fixed frame 110 has symmetrically formed grooves 120. A screw 130 is rotatably connected within the grooves 120. A first motor 140 is fixedly mounted on the top of the fixed frame 110. One end of the screw 130 is connected to the shaft of the first motor 140. A movable frame 150 is threadedly connected to the side wall of the screw 130. A second motor 160 is fixedly mounted on the top of the movable frame 150. A drill rod 170 is rotatably connected to the bottom of the movable frame 150. The shaft of the motor is connected to the top of the drill rod 170. The infrared ranging sensor 200 is fixedly mounted on the front side wall of the movable frame 150. A controller 210, a display screen 220, and a control panel 230 are fixedly mounted on the right side wall of the fixed frame 110. The infrared ranging sensor 200 and the display screen 220 are connected to the controller 210. The system is electrically connected. Specifically, the first motor 140 drives the screw 130 to rotate, thereby moving the moving frame 150 up and down. The moving frame 150 pushes the drill rod 170 into the soft soil layer. The second motor 160 drives the drill rod 170 to rotate, thus performing drilling. The positioning hole 180 facilitates the positioning of the drill rod 170 to ensure stability during drilling. As the moving frame 150 pushes downward, an infrared ranging sensor emits an infrared beam onto the base 100 to measure the distance between the base 100 and the infrared ranging sensor, thus accurately measuring the drilling depth of the drill rod 170. The detection data is displayed on the display screen 220 for easy observation of the drilling depth. According to the drilling requirements, the control panel 230 is used to control the device and thus control the drilling depth.

[0027] The top of the fixed frame 110 is provided with a handle, and the side wall of the handle is provided with an anti-slip coating. Specifically, the handle makes it easy to pick up the device and carry it.

[0028] The movable frame 150 is provided with a rotating hole, and the motor shaft is embedded in the rotating hole. Specifically, the rotating hole facilitates the connection between the motor and the drill rod 170, making installation convenient.

[0029] A bearing is provided on the top of the base 100, and the bottom end of the screw 130 is embedded in the bearing. Specifically, the bearing facilitates the support of the bottom end of the screw 130, so that the base 100 and the screw 130 are rotatably connected through the bearing.

[0030] The bottom of the drill rod 170 is pointed, which makes it easy to quickly drill into the soil and facilitates drilling.

[0031] The positioning hole 180 is provided correspondingly to the drill rod 170. The drill rod 170 is embedded in the positioning hole 180. Specifically, the positioning hole 180 facilitates the positioning of the drill rod 170 during drilling and ensures that the drill rod 170 is vertical.

[0032] Combination Figures 1-4 The specific usage process of the saturated soft loess foundation pit slope anchor drilling device according to this embodiment is as follows: During the use of the saturated soft loess foundation pit slope anchor drilling device, the first motor 140 drives the screw 130 to rotate, thereby driving the moving frame 150 to move up and down. The moving frame 150 pushes the drill rod 170 into the soft soil layer. The second motor 160 drives the drill rod 170 to rotate, thus rotating the drill rod 170 to perform drilling work. The positioning hole 180 facilitates the positioning of the drill rod 170, ensuring vertical stability during drilling. During the downward push, the infrared ranging sensor moves downward synchronously. The infrared ranging sensor emits an infrared beam that shines onto the base 100, thereby measuring the distance between the base 100 and the infrared ranging sensor. This facilitates accurate measurement of the drilling depth of the drill rod 170. The detection data is displayed on the display screen 220 for easy observation of the drilling depth. According to the drilling requirements, the control panel 230 is used to control the device to control the drilling depth, preventing the drilling from being too deep or too shallow, thus improving the installation effect of the anchor rod and the stability of the foundation pit slope.
