[0026] EMBODIMENT
[0027] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the technical scheme in the embodiment of the application effectively solves the technical problem that the probe is inserted downward through the probe rod, the probe rod and the measuring device are subjected to upward reverse force and vertical reverse force, the connecting end of the measuring device and the ground is easily loosened, the probe rod shakes and deviates during the downward insertion of the probe, and the verticality and uniformity of penetration are affected, and the overall idea is as follows:
[0028] To address the problems existing in the prior art, this utility model provides a bearing capacity measuring device, including a static cone penetrometer 11, a probe 12, and a sensor 13. Two upwardly deflecting lateral auxiliary plates 14 are rotatably mounted on both sides of the static cone penetrometer 11. Each lateral auxiliary plate 14 has a fixedly installed stabilizing plate 17 for connection and support. Each stabilizing plate 17 has a fixedly installed soil insertion plate 18 at its bottom for inserting and positioning the static cone penetrometer 11. Two horizontally rotating rotatable plates 19 are rotatably mounted on the top of each soil insertion plate 18. By flipping the rotatable plates 19, the top of the rotatable plates 19... The rotating shaft is connected to the soil insertion plate 18, and the stabilizing plate 17 and the soil insertion plate 18 are inserted into the soil. The soil insertion plate 18 drives the rotatable plate 19 into the soil. By deflecting the rotatable plate 19, the two rotatable plates 19 are deflected to one side synchronously. The two rotatable plates 19 unfold at the side end of the soil insertion plate 18, increasing the force-bearing area. When the rotatable plate 19 is subjected to an upward pulling force or a horizontal sliding force, the rotatable plate 19 can provide additional resistance, improve the stability and load-bearing capacity of the plate, and provide a certain lateral support to resist these lateral forces, which helps to keep the probe 13 inserted in the vertical direction.
[0029] By installing probe 13 at the bottom of probe 12 and ensuring a secure connection, probe 12 is connected to static cone penetrometer 11 to prepare for penetration. Static cone penetrometer 11 is started, allowing probe 13 to penetrate the soil layer at a constant speed. During the penetration process, the data acquisition system records the changes in probe tip resistance and sidewall friction with depth in real time, and also records the penetration depth. The data acquisition system begins to record the changes in probe tip resistance and sidewall friction with depth and then processes the collected data.
[0030] At least two positioning cones 15 are fixedly installed at the bottom of each side auxiliary plate 14 to lock the position of the static cone penetrometer 11. Two support diagonal rods 16 for fixed support are rotatably installed at the top of each side auxiliary plate 14. A rotatable leaf plate is installed at the top of the support diagonal rods 16. At the same time, a groove is opened at the top of the side auxiliary plate 14. The support diagonal rods 16 can be flipped to one side to enter the top of the side auxiliary plate 14. Then, by flipping the side auxiliary plate 14 downward, the side auxiliary plate 14 is bent towards the side of the static cone penetrometer 11, reducing storage space and making it easy to carry.
[0031] Two magnetic plates 26 made of magnetic material are fixedly installed on both sides of the static cone penetrometer 11. The magnetic plates 26 attract the upward-flipping side auxiliary plate 14, so that the side auxiliary plate 14 is fixed to the side of the static cone penetrometer 11.
[0032] Two freely rotating push rods 21 are rotatably installed inside each stabilizing plate 17. Two locking sleeves 22 for locking the position of the push rods 21 are fixedly installed at the bottom of each stabilizing plate 17. By pressing down on the push rods 21, the push rods 21 slide inside the stabilizing plate 17. The push rods 21 drive the support ring 24 to slide down, and the support ring 24 drives the protrusion 23 to slide down inside the locking sleeve 22, thereby releasing the fixed state of the push rods 21.
[0033] Each push rod 21 has a support ring 24 fixedly installed at its bottom end. Each support ring 24 has at least two protruding rods 23 fixedly installed at its top end, which are connected to the locking sleeve 22. Each support ring 24 has a synchronous rotating sleeve 25 with both ends compressed fixedly installed at its bottom end. By rotating the push rod 21, the end of the push rod 21 drives the synchronous rotating sleeve 25 to rotate. At the same time, the end of the synchronous rotating sleeve 25 is connected to the rotatable plate 19. The push rod 21 can not only push the rotatable plate 19 to deflect, but also the vertical sliding of the push rod 21 inside the stabilizing plate 17 can fix the angle of the rotatable plate 19.
[0034] Working principle:
[0035] The first step involves installing probe 13 at the bottom of probe 12 and ensuring a secure connection. Probe 12 is then connected to the static cone penetration tester 11 in preparation for penetration. The static cone penetration tester 11 is started, allowing probe 13 to penetrate the soil layer at a constant speed. During penetration, the data acquisition system records the changes in probe tip resistance and sidewall friction with depth in real time, while also recording the penetration depth. The data acquisition system then begins recording the changes in probe tip resistance and sidewall friction with depth and organizes the collected data.
[0036] The second step involves flipping the rotatable plate 19, whose top end is connected to the soil insertion plate 18 via a pivot. This inserts the stabilizing plate 17 and the soil insertion plate 18 into the soil. The soil insertion plate 18 then drives the rotatable plate 19 into the soil. By deflecting the rotatable plate 19, both plates rotate synchronously to one side. The two rotatable plates 19 unfold at the side end of the soil insertion plate 18, increasing the contact area. When the rotatable plate 19 is subjected to upward pulling force or horizontal sliding force, it provides additional resistance, improving the stability and load-bearing capacity of the plate. It also provides some lateral support to resist these lateral forces, helping to protect the soil. Insert the probe 13 in the vertical direction, and press down on the push rod 21 to make it slide inside the stabilizing plate 17. The push rod 21 drives the support ring 24 to slide downward, and the support ring 24 drives the protrusion 23 to slide downward inside the locking sleeve 22, releasing the fixed state of the push rod 21. By rotating the push rod 21, the end of the push rod 21 drives the synchronous rotating sleeve 25 to rotate. At the same time, the end of the synchronous rotating sleeve 25 is connected to the rotatable plate 19. The push rod 21 can not only push the rotatable plate 19 to deflect, but also fix the angle of the rotatable plate 19 by sliding vertically inside the stabilizing plate 17.
[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
