Description

Technical Field

[0001] The invention relates to the technical field of highway foundation drilling sampling, and in particular to a highway foundation drilling sampling process. Background Art

[0002] In the vast field of highway construction and maintenance, the nature and stability of foundation soil are key factors in ensuring the safety of highway structures, driving comfort and extending service life. With the continuous improvement of highway engineering technical standards and the increasing complexity of geological conditions, the need to understand foundation soil is becoming more urgent. Boring sampling technology, with its direct, accurate and quantifiable advantages, has become an indispensable tool for evaluating foundation bearing capacity, deformation characteristics, moisture content, soil layer distribution and potential geological disaster risks. By precisely controlling the drilling position, depth and sampling method, representative samples of different depths and different soil layers can be effectively collected, providing valuable first-hand information for subsequent laboratory analysis.

[0003] For example, the Chinese patent authorization announcement number CN113047256B, a sampling system for foundation detection of water conservancy projects, includes a bracket, the inner wall of the bracket is respectively connected with a first slide groove, and the first slide groove is movably sleeved with a first slider. The present invention sets an auxiliary mechanism, and the lifting plate moves downward, so that the first sleeve can drive the sleeve rod to move downward, so that the L-shaped plate connected to the bottom end of the sleeve rod can be squeezed, and the L-shaped plate can be moved to the inner wall of the protective cover, which is convenient for the drill rod to drill the foundation. At the same time, when the lifting plate moves upward, the sleeve rod can have an upward force on the top of the L-shaped plate, which is convenient for the L-shaped plate to flip and move on the surface of the first connecting rod, so that the soil covered by the protective cover is buried inside the borehole. At the same time, the first spring prevents the sleeve rod from squeezing and damaging the L-shaped plate or the protective cover, affecting its subsequent use. However, when sampling soil, it is not possible to accurately sample the appropriate depth and soil of different depths is easily mixed during sampling. At the same time, the above device is prone to shaking and being unstable when drilling holes in the soil, thereby affecting the drilling effect. Summary of the invention

[0062] The working principle of the present invention is as follows: first, the support frame 1 is pushed, so that the support frame 1 is moved to the position where the highway foundation drilling sampling is to be carried out through the connecting plate 2 and the universal wheel 4, and the pushing plate 300 is knocked with an external tool to make the rod body 302 with the stable drill bit 303 sink into the soil of the highway foundation, and a driving motor 301 is set.

[0064] When it moves to a suitable depth, an adjusting motor 901 is set, and the output end of the adjusting motor 901 rotates along the connecting frame 900 with the screw rod 902. The screw rod 902 rotates to make the sliding block 903 move along the slide groove opened on the connecting frame 900 and the screw rod 902 to the square groove 12 set on the connecting shaft 8, so that the small gear 905 and the internal gear 907 are meshed through the square groove 12. An electric push rod 908 is set, and the electric push rod 908 extends from the protective pad 11 with the collecting block 909, and the connection When the shaft 8 rotates, it drives the connecting frame 900, the screw rod 902, the sliding block 903, the rotating shaft 904, and the pinion 905 to rotate. The pinion 905 drives the internal gear 907 and the connecting ring 906 to rotate. The connecting ring 906 drives the electric push rod 908 and the collecting block 909 to rotate. The collecting block 909 rotates to collect and sample the soil deep in the road foundation. After the collection, the electric push rod 908 is set again. The electric push rod 908 drives the soil collected in the collecting block 909 to move into the protective tube 10.

[0065] After the sampling of the highway foundation soil is completed, the drilling motor 7 is stopped so that the drilling motor 7 with the connecting shaft 8 and the drilling drill bit 13 stops rotating, and the hydraulic cylinder 5 is set. The output end of the hydraulic cylinder 5 pulls the movable plate 6, so that the movable plate 6 with the drilling motor 7, the connecting shaft 8, and the drilling drill bit 13 moves upward along the slide groove set on the inner side of the support frame 1 to remove the soil, and the electric push rod 908 is set again. The electric push rod 908 extends out with the collecting block 909 to take out the soil sample in the collecting block 909 to complete the sampling;

[0066] The user puts his hand into the protective pad 11 to rotate and disassemble the nut 15 and the bolt 14, so that the drilling drill bit 13 falls off from the connecting shaft 8, making it easier to clean the soil that has entered the protective tube 10.
