Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical testing equipment, in particular to a highway engineering geological survey rock and soil testing device. Background Art

[0002] The geotechnical ball meter is a powerful engineering testing equipment, especially suitable for engineering fields such as highways and railways. It mainly measures the rebound performance of materials after being stressed to indirectly derive key indicators such as the material's modulus of resilience. These indicators are crucial for evaluating the bearing capacity and deformation characteristics of the roadbed.

[0003] Therefore, in the inspection of roadbed rock and soil, the use of a geotechnical falling ball instrument can quickly test the soil rebound performance at multiple locations and provide practical data support. Through these data, engineers can more accurately understand the mechanical properties of roadbed materials, thereby judging the stability and safety of the roadbed. For example, the Chinese utility model patent disclosed by publication number CN111521496B: Field testing system for mechanical properties of falling ball geotechnical materials, when inspecting the roadbed, its metal rigid ball will fall freely and hit the roadbed, thereby detecting the mechanical properties of the roadbed material. However, when the metal rigid ball is dropped and hit, a bracket is usually used to ensure the verticality of the operating handle connected to the metal rigid ball, thereby ensuring the stable fall of the metal rigid connected ball. However, when assembling the entire falling ball instrument, the components of the bracket need to be installed in sequence, and the metal rigid ball and the operating handle need to be assembled, which makes the disassembly and assembly process of the falling ball instrument complicated, and the convenient disassembly and assembly of the falling ball instrument cannot be achieved.

[0024] like Figure 1-Figure 3As shown, two first fixed shafts 13 are fixedly installed on both sides of the first connecting block 4, two swing grooves 10 are provided on the outer side of the semicircular bottom plate 1, and a first ball groove 11 is provided in the middle of the inner side of the swing groove 10, and two first connecting grooves 12 are respectively provided on the opposite sides of the two semicircular bottom plates 1, and the two first connecting grooves 12 on one side of the two semicircular bottom plates 1 are respectively rotatably connected to the corresponding side of the first connecting block 4 through two first fixed shafts 13. The opening of the first ball groove 11 can provide conditions for the movable installation of one end of the support rod 7, and the two semicircular bottom plates 1 are rotatably connected to the first fixed shaft 13 through the first connecting block 4, so that the two semicircular bottom plates 1 can be folded and stored.

[0025] like Figure 1-Figure 4 As shown, first embedding grooves 14 are provided on both sides of the two second connecting blocks 6, two second fixed shafts 15 are fixedly installed on the side of the second connecting block 6 away from the rod sleeve 5, a semicircular cover 16 is fixedly installed in the middle of the semicircular top plate 2, a second connecting groove 17 is provided at the lower end of the semicircular top plate 2, two second embedding grooves 18 are provided at the top of the second connecting groove 17, and a fixing seat 19 is also fixedly installed on the semicircular top plate 2 located above the second embedding groove 18, and a communicating second ball groove 20 is provided in the fixing seat 19 and the semicircular top plate 2, and the semicircular top plate 2 is rotatably installed between the two second connecting blocks 6 through the second connecting groove 17 and the second fixed shaft 15. By setting the rod sleeve 5, the vertical guiding movement of the operating handle 8 can be facilitated, and the two groups of second connecting blocks 6 and the second fixed shaft 15 arranged on the outside of the rod sleeve 5 are conducive to the rotational connection and folding storage of the two semicircular top plates 2. Rotating balls 21 are fixedly installed at both ends of the support rod 7. The rotating ball 21 at one end of the support rod 7 is rotatably installed in the corresponding first ball groove 11, and the rotating ball 21 at the other end of the support rod 7 is rotatably installed in the corresponding second ball groove 20.

[0026] It should be noted that the utility model is a geotechnical detection device for highway engineering geological survey. When detecting the roadbed of the highway, the two semicircular top plates 2 can be directly carried by hand and the entire device can be moved to the desired position. Then, the two semicircular top plates 2 can be manually separated and unfolded, so that the semicircular top plates 2 can be rotated on the second fixed axis 15 on one side of the two second connecting blocks 6 with the axial hole in the second connecting groove 17 as the axis.

Then, the data analyzer 3 is placed flat on the roadbed and connected to one end of the operating handle 8 through a connecting line, so that the data analyzer 3 is electrically connected to the acceleration sensor in the ball crown 9. When testing the roadbed, it is only necessary to hold the operating handle 8 to lift the ball crown 9 to a certain height, and then release the operating handle 8 to allow the ball crown 9 to fall freely and hit the roadbed. The collision process between the ball crown 9 and the roadbed soil is divided into a compression process and a rebound process. By testing the contact time of the compression process of the roadbed soil, its deformation modulus can be calculated, and then by testing the contact time of the rebound process of the soil, its rebound modulus can be calculated. At the same time, according to the elasticity theory and relevant empirical formulas, the base bed coefficient, Beckmann deflection, and the dry density, compaction degree, relative density, etc. of the soil base can also be calculated.
