Description
Technical Field
[0001] This utility model relates to the field of geotechnical surveying technology, and in particular to a geotechnical engineering surveying device. Background Technology
[0002] Soil and rock are a general term for rocks and soil. In terms of rocks, they are the main materials that make up the Earth's crust. According to their formation, they can be divided into igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks are formed by the cooling and solidification of magma, such as granite. They have relatively coarse grains and come in various colors. Due to their hardness, they are often used as decorative stone and foundation materials in construction. Sedimentary rocks are formed at relatively shallow depths of the Earth's surface by the weathering products of other rocks and some volcanic ejecta, which are transported, deposited, and diagenetic by water or glaciers. For example, limestone is mainly composed of calcium carbonate. It is the main raw material for making lime and cement and is also an important source of building stone.
[0003] Geotechnical engineering surveying equipment is a series of specialized devices used for investigating, testing, and analyzing soil and rock masses. In the field phase of geotechnical engineering surveys, drilling equipment, such as rotary drilling rigs, is used to cut through the soil and rock to obtain core samples. This allows engineers to intuitively understand the stratification and lithology of soil and rock at different depths, which is crucial for determining the structure of underground soil and rock. Previously, geotechnical engineering surveying equipment was large and inconvenient for use in confined environments. However, modern geotechnical engineering surveying equipment is available in various types and sizes to suit different working environments. Existing geotechnical engineering surveying equipment has a fixed mechanism integrated with the outer frame, which can cause the equipment to tilt in uneven environments, affecting the surveying work.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 2 and Figure 4This utility model provides an embodiment of a geotechnical engineering surveying device, comprising a soil-collecting shell 1, with multiple fixing plates 3 equidistantly fixed around the outer wall of the soil-collecting shell 1, rotating blocks 4 rotatably connected to adjacent sides of the multiple fixing plates 3, connecting rods 5 fixedly connected to the outer sides of the multiple rotating blocks 4, fixing plates 3 fixing the position of connecting rods 5 through rotating blocks 4, fixing rings 6 fixedly connected to the ends of the multiple connecting rods 5, fixing columns 7 slidably connected to the inner sides of the multiple fixing rings 6, fixing bolts 8 slidably connected to the middle right side of the multiple fixing rings 6, fixing rings 6 cooperating with fixing bolts 8 to fix the fixing columns 7 inserted in the fixing rings 6, multiple ground spikes 9 equidistantly fixed to the bottom of the multiple fixing columns 7, a soil drilling and collection mechanism 2 installed on the inner side of the soil-collecting shell 1, the soil drilling and collection mechanism 2 being used to collect soil and rock for exploration, pull rings 10 fixedly connected to the right side of the multiple fixing bolts 8, the pull rings 10 being used to pull the fixing bolts 8, and nuts 12 threadedly connected to the left end of the outer wall of the multiple fixing bolts 8, the nuts 12 being used to stabilize the position of the fixing bolts 8;
[0032] Specifically, firstly, the multiple connecting rods 5 fixed to the outside of the soil shell 1 by the fixing plate 3 are rotated open by the cooperating rotating block 4. After the multiple connecting rods 5 are fully extended, the multiple fixing posts 7 are inserted into the fixing rings 6 fixed at the end of each connecting rod 5. Then, each fixing post 7 is pressed down forcefully, so that the ground spikes 9 fixed under the fixing post 7 are driven into the ground, thereby fixing the geotechnical engineering survey device. The balance of the geotechnical engineering survey device is maintained by adjusting each fixing post 7 individually. Then, the fixing bolts 8 are inserted into the corresponding holes on the fixing rings 6 and fixing posts 7 to fix the fixing posts 7. The fixing bolts 8 can be pulled out more easily by the pull ring 10, and the nut 12 is put on the end of the fixing bolts 8 to prevent them from falling off.
[0033] Reference Figure 3 and Figure 5 The soil drilling and collection mechanism 2 includes a threaded rod 201. The outer side of the threaded rod 201 is threadedly connected to the middle of the top wall of the soil collection shell 1. A limiting plate 202 is fixedly connected to the top of the threaded rod 201. The limiting plate 202 is used to limit the position of the threaded rod 201. A rocker arm 203 is fixedly connected to the top of the limiting plate 202. The rocker arm 203 drives the threaded rod 201 to rotate through the limiting plate 202. A soil collection drill bit 204 is fixedly connected to the bottom of the threaded rod 201. The threaded rod 201 drives the soil collection drill bit 204 to rotate. Sliding grooves 205 are equidistantly opened on the outer side of the soil collection shell 1. A fixing frame 206 is slidably connected to the inner side of multiple sliding grooves 205. The fixing frame 206 is fixed to the outside of the soil collection shell 1 through the sliding grooves 205. A rubber sleeve 13 is fixedly connected to the outer wall of the rocker arm 203. The rubber sleeve 13 is used to improve the grip of the rocker arm 203.
[0034] Specifically, the rocker arm 203 is rocked to rotate the limiting plate 202. As the limiting plate 202 rotates, the threaded rod 201 fixed below it also rotates synchronously. When the threaded rod 201 rotates, it drives the soil extraction drill bit 204 fixed below it to start rotating. The rotation of the soil extraction drill bit 204 digs out the soil and rock to be surveyed. The excavated soil and rock will be carried into the soil receiving shell 1 by the soil extraction drill bit 204 in sequence. The fixing frame 206 fixed to the outside of the soil receiving shell 1 by the sliding groove 205 works with the limiting plate 202 and the soil receiving shell 1 to limit the survey depth of the soil extraction drill bit 204. The rubber sleeve 13 fixed to the outside of the rocker arm 203 can improve its grip.
[0035] Reference Figure 1 and Figure 4 Each of the tops of the fixed columns 7 is fixedly connected to a limiting block 11, which limits the downward pressure range of the fixed column 7. The outer wall of the rubber sleeve 13 is provided with anti-slip texture 14, which improves the anti-slip properties of the rubber sleeve 13. The front side of the soil shell 1 is provided with a scale groove 15, which is used to observe the survey depth.
[0036] Specifically, the limiting block 11 fixed on the fixing column 7 can prevent it from falling off the fixing ring 6, the anti-slip texture 14 opened on the outside of the rubber sleeve 13 can improve its anti-slip performance, and the scale groove 15 opened on the outside of the soil shell 1 makes it easy to observe the survey depth.
[0037] Working principle: When fixing the geotechnical engineering surveying device in an uneven environment, firstly, the multiple connecting rods 5 fixed to the outside of the soil shell 1 by the fixing plate 3 are rotated open by the cooperating rotating block 4. After the multiple connecting rods 5 are fully extended, the multiple fixing posts 7 are inserted into the fixing rings 6 fixed at the end of each connecting rod 5. Then, each fixing post 7 is pressed down forcefully, so that the ground spikes 9 fixed under the fixing post 7 are driven into the ground, thereby fixing the geotechnical engineering surveying device. The balance of the geotechnical engineering surveying device is maintained by adjusting each fixing post 7 individually. Then, the fixing bolts 8 are inserted into the corresponding holes on the fixing rings 6 and fixing posts 7 to fix the fixing posts 7. This achieves the effect of avoiding tilting when fixing the geotechnical engineering surveying device, thereby avoiding its impact on the exploration work.
[0038] Once the geotechnical engineering surveying device is fixed in place, the rocker arm 203 is cranked to rotate the limiting plate 202. As the limiting plate 202 rotates, the threaded rod 201 fixed below it also rotates synchronously. When the threaded rod 201 rotates, it drives the soil extraction drill bit 204 fixed below it to start rotating. The rotation of the soil extraction drill bit 204 excavates the soil and rock to be surveyed, and the excavated soil and rock are carried into the soil receiving shell 1 by the soil extraction drill bit 204. The fixing frame 206, which is fixed to the outside of the soil receiving shell 1 by the sliding groove 205, works with the limiting plate 202 and the soil receiving shell 1 to limit the surveying depth of the soil extraction drill bit 204, thereby achieving the effect of collecting and surveying the soil and rock to be surveyed.
