Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0023] Please see Figures 1 to 5 The highway engineering inorganic binder stabilized material erosion test device in this embodiment includes a main body box 1. A partition 2 is fixedly installed inside the main body box 1. The partition 2 divides the space of the main body box 1 into a drive chamber 3 and a test chamber 4. A sliding plate mechanism 5 is fixedly installed inside the test chamber 4. A test cylinder 6 is placed on the top of the sliding plate mechanism 5. A compaction component 7 is provided on the top of the partition 2 and inside the drive chamber 3. A control cabinet 8 is installed on the left side of the main body box 1.
[0024] The main body box 1 has three hinged doors on its front, with one door in the drive cavity 3 and two doors in the test cavity 4. A removable cover plate 9 is provided on the main body box 1, corresponding to the right half of the test cavity 4.
[0025] The slide mechanism 5 includes a bracket 501 fixedly connected to the inner wall of the main body box 1. A slide rail 502 is fixedly installed on the top of the bracket 501. A placement platform 503 is slidably connected to the top of the slide rail 502. The test cylinder 6 is located above the placement platform 503. Four rollers are fixedly installed at the bottom of the placement platform 503. The rollers are located at the four corners of the bottom and inside the slide rail 502.
[0026] By opening the door of the test chamber 4, the placement platform 503 is first moved to the right side via the slide rail 502. Since the main body 1 has a removable cover plate 9, it is easy to open the cover plate 9 to add test material to the test cylinder 6 on the placement platform 503. After adding the material, the placement platform 503 is slid under the compaction component 7, and then the compaction component 7 is controlled to perform the test on the test cylinder 6. This facilitates use and improves work efficiency.
[0027] The compaction assembly 7 includes a connecting frame 701 fixedly connected to the top of the partition 2. A connecting plate 702 is fixedly connected to the surface of the connecting frame 701. A first motor 703 is fixedly mounted on the top of the connecting plate 702. A lead screw 704 is fixedly connected to the output shaft of the first motor 703. The lead screw 704 is parallel to the connecting frame 701, and its bottom end is movably connected to the top of the partition 2. A limiting rail 705 is fixedly mounted on the surface of the connecting plate 702. A mounting bracket 706 is slidably connected to the surface of the limiting rail 705. The mounting bracket 706 and the lead screw 704 are connected to the top of the partition 2. The rod 704 is threaded. The surface of the mounting bracket 706 is fixedly connected to the second motor 707. The output shaft of the second motor 707 is fixedly connected to the turntable 708. The surface of the turntable 708 is fixedly connected to the eccentric rod 709. The surface of the eccentric rod 709 is rotatably connected to the transmission rod 710. The end of the transmission rod 710 away from the eccentric rod 709 is rotatably connected to the compaction element 711. The compaction element 711 extends through the partition 2 into the interior of the test chamber 4. A sleeve is fixedly installed on the partition 2. The compaction element 711 extends through the sleeve to the bottom of the partition 2.
[0028] The connecting plate 702 has scale lines on the side facing the door, and the bracket 501 has a limit sensor installed on the side facing the door. The limit sensor is used to control the movement of the mounting bracket 706.
[0029] The first motor 703 drives the lead screw 704 to rotate. The lead screw 704 is threadedly connected to the mounting bracket 706. Under the action of the limit rail 705, the mounting bracket 706 can move. After moving downwards to a certain stroke, the second motor 707 works, driving the turntable 708 to rotate. Due to the eccentric design of the eccentric rod 709 on the turntable 708, the eccentric rod 709 can drive the compaction component 711 to move up and down reciprocally through the transmission rod 710, thereby compacting the water-added sample. After compaction, it is convenient for subsequent measurements.
[0030] It should be noted that subsequent tests include erosion tests, which are crucial for evaluating the erosion resistance of inorganic binder stabilized materials. These tests simulate the stability and erosion resistance of the material structure when the pavement is subjected to the erosion effects of rainwater or other fluids during use. The test results are essential for understanding the water stability of the material and designing more durable pavement structures.
[0031] Specifically, place the prepared specimen into the rinsing tank. Secure the specimen to the bottom of the rinsing tank using clamps (to protect the specimen from damage by the clamps, place a rubber pad radially between the specimen and the clamps), then firmly place the rinsing tank containing the specimen onto the rinsing testing machine. Pour clean water into the rinsing tank, ensuring the water level is 5mm above the top surface of the specimen. Place a rubber pad with longitudinal and transverse holes on the specimen. Adjust the force of the rinsing testing machine to a peak impact force of 0.5MPa, a rinsing frequency of 10Hz, and a rinsing time of 30min. After rinsing, remove the rinsing tank from the base plate of the rinsing testing machine and carefully pour the turbid water and rinsing material into a metal basin for sedimentation. After 12 hours of sedimentation, carefully pour out the clear water from the top of the basin, and dry the remaining sediment in an oven. Then weigh the sediment to obtain the cumulative rinsing amount for 30min.
[0032] Erosion testing can assess the stability and durability of inorganic binder stabilized materials when subjected to water erosion. This is crucial for ensuring that materials maintain their structural integrity during rainy seasons or humid environments. Through erosion testing, engineers can understand the differences in erosion resistance among different materials and proportions, thereby optimizing material design and selection to improve the service life and performance of highways.
[0033] The working principle of the above embodiments is as follows:
[0034] By opening the door of the test chamber 4, the placement platform 503 is first moved to the right side via the slide rail 502. Since the main body box 1 is equipped with a detachable cover plate 9, it is convenient to open the cover plate 9 to add test material to the test cylinder 6 on the placement platform 503. After adding, the placement platform 503 is slid under the compaction component 7, and the first motor 703 is turned on. The first motor 703 drives the lead screw 704 to rotate. The lead screw 704 is threadedly connected to the mounting bracket 706. Under the action of the limit rail 705, the mounting bracket 706 can move. After moving down to a certain stroke, the second motor 707 works, driving the turntable 708 to rotate. Due to the eccentric design of the eccentric rod 709 on the turntable 708, the eccentric rod 709 can drive the compaction component 711 to move up and down through the transmission rod 710, thereby compacting the sample after water addition. After compaction, it is convenient for subsequent measurement.
