Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of geotechnical compaction test, in particular to a geotechnical compaction test compaction cylinder. Background Art
[0002] Geotechnical compaction test refers to a method of using a hammer to compact soil samples to understand the compaction characteristics of the soil. This method uses different compaction work (hammer weight × drop distance × number of hammer blows) to hammer soil samples with different water contents, and measures the corresponding dry bulk density to obtain the maximum dry bulk density, which generally refers to the aggregate stacking or compact density and the optimal water content, providing a basis for the design and construction of fill projects.
[0003] Announcement No. CN211784656U discloses a geotechnical compaction test compaction cylinder, including a square base plate, the upper surface of which is provided with two parallel first concave dovetail grooves and two first pin positioning grooves; it also includes a compaction cylinder composed of a left half cylinder and a right half cylinder, and an annular step composed of a left half ring and a right half ring is also provided on the outer circumference of the bottom of the compaction cylinder, and a first dovetail groove-shaped protrusion is provided on the lower surface of the annular step; the left half cylinder is provided with a second dovetail groove-shaped protrusion on the contact surface with the right half cylinder, and the right half cylinder is provided with a second concave dovetail groove.
[0004] However, this technical solution has the following defects:
[0005] 1. After the compaction and weighing are completed, the soil sample needs to be taken out from the compaction cylinder. The current conventional method is to use manual layered excavation to dig out the soil sample with simple tools, which is time-consuming, labor-intensive and inefficient. Alternatively, the demolding is performed mechanically with the help of a demolding device, which has high demolding efficiency. However, the cost of the specially configured equipment for the demolding device is high and the equipment utilization rate is low.
[0006] 2. During the compaction test using a compaction cylinder, a measuring device is required to measure the compaction height of the soil in the compaction cylinder. However, the compaction cylinder itself does not have a measuring device, and additional measuring tools are required for measurement, which is relatively cumbersome and not convenient enough. For this reason, we propose a geotechnical compaction test compaction cylinder to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] See also Figure 1-7 , the utility model provides an embodiment: a geotechnical compaction test compaction cylinder, comprising a compaction cylinder 1;
[0032] A sleeve 2 is installed on the compaction cylinder 1, and ear plates 3 are fixedly installed on the left and right sides of the sleeve 2. Through holes 4 are opened in the two sets of ear plates 3. A layered component is movably installed on the compaction cylinder 1. A chassis 9 is installed at the lower end of the compaction cylinder 1. A fixed component 10 is provided at the connection between the chassis 9 and the fixed component 10. A measuring component is installed on the ear plate 3 at the left end of the sleeve 2. This device is installed in the compaction cylinder 1 through the layered component, so that when the compaction cylinder 1 is subjected to a compaction test, it is convenient to separate and take out the compacted soil, and the layered compacted soil is measured by the measuring component.
[0033] Furthermore, the diameter of the inner wall at the upper end of the compaction cylinder 1 is the same as the diameter of the outer wall at the lower end of the sleeve 2, and the outer wall at the lower end of the compaction cylinder 1 is the same as the inner wall at the upper end of the chassis 9. This structure is based on the size of the inner wall diameter at the upper end of the compaction cylinder 1 and the outer wall at the lower end of the sleeve 2 and the outer wall at the lower end of the compaction cylinder 1 and the inner wall at the upper end of the chassis 9, so that the upper and lower ends of the compaction cylinder 1 are tightly connected with the sleeve 2 and the chassis 9.
[0034] Furthermore, the layered component includes multiple groups of slots 5, which are annularly arranged on the inner wall of the compaction cylinder 1, and a first side edge 6 and a second side plate 7 are movably inserted in the compaction cylinder 1. Multiple groups of plug blocks 8 are arranged on the outer walls of the first side edge 6 and the second side plate 7, and the multiple groups of plug blocks 8 are movably inserted in the multiple groups of slots 5. This structure inserts the first side edge 6 and the second side plate 7 in the multiple groups of slots 5 through the multiple groups of plug blocks 8, thereby separating the inner wall of the compaction cylinder 1 from the soil, making it convenient to remove and separate the soil from the compaction cylinder 1 after compaction.
[0035] Furthermore, the multiple groups of plug-in blocks 8 and the inner walls of the multiple groups of slots 5 are both dovetail-shaped, and the multiple groups of plug-in blocks 8 are adapted to the inner walls of the multiple groups of slots 5. This structure is based on the shapes of the multiple groups of plug-in blocks 8 and the inner walls of the multiple groups of slots 5, so that when the multiple groups of plug-in blocks 8 are inserted into the multiple groups of slots 5, the multiple groups of plug-in blocks 8 can only slide up and down in the multiple groups of slots 5.
[0036] Furthermore, the measuring assembly includes a fixed rod 11, which is fixedly mounted on the ear plate 3 at the left end of the sleeve 2. A rotating plate 12 is rotatably mounted on the upper end of the fixed rod 11. A measuring rod 13 is movably inserted in the rear end of the rotating plate 12. A spring 14 is sleeved between the upper end of the measuring rod 13 and the upper side of the rotating plate 12. The upper end of the spring 14 is fixedly connected to the upper end of the measuring rod 13, and the lower end of the spring 14 is fixedly connected to the upper side of the rotating plate 12. When the soil in the compaction cylinder 1 is compacted in layers, this structure can measure the soil height in the compaction cylinder 1 by pulling the measuring rod 13 to move it into the compaction cylinder 1, and by the action of the restoring elastic force of the spring 14, the lower end of the measuring rod 13 is fitted with the upper side of the soil in the compaction cylinder 1.
[0037] Furthermore, the outer wall of the measuring rod 13 is provided with scale values, and the scale values on the outer wall of the measuring rod 13 are arranged from bottom to top. This structure increases the accuracy of soil measurement when the measuring rod 13 measures the soil in the compaction cylinder 1 according to the scale values on the outer wall of the measuring rod 13.
[0038] Furthermore, the inner wall diameter of the sleeve 2 is the same as the inner wall diameter between the first side edge 6 and the second side plate 7. This structure is based on the inner wall diameters of the sleeve 2 and the inner walls of the first side edge 6 and the second side plate 7, so that after the soil enters the first side edge 6 and the second side plate 7 from the sleeve 2, the inner walls remain the same from bottom to top.
[0039] Furthermore, the measuring rod 13 is made of steel, and an anti-corrosion coating is provided on the surface of the measuring rod 13. This structure enables the measuring rod 13 to have certain wear resistance and durability according to the material of the measuring rod 13.
[0040] Furthermore, the length of the rotating plate 12 is greater than the length between the fixed rod 11 and the inner wall of the sleeve 2. According to the length of the rotating plate 12, the measuring rod 13 at the rear end of the rotating plate 12 is moved into the compaction cylinder 1 to measure the soil.
[0041] Embodiment 1:

The multiple groups of card blocks 1001 are movably inserted in the multiple groups of card slots 1002. When this structure sleeves the chassis 9 on the lower end of the compaction cylinder 1, the multiple groups of card blocks 1001 are inserted in the multiple groups of card slots 1002, so that the chassis 9 and the compaction cylinder 1 can be fixedly connected, and the soil in the compaction cylinder 1 can be prevented from falling off and scattering when the compaction cylinder 1 is taken.
[0043] Embodiment 2:
[0044] The fixing assembly 10 includes a threaded ring 1003, which is provided on the outer wall of the lower end of the compaction cylinder 1 and the inner wall of the upper end of the chassis 9. When the chassis 9 is installed on the lower end of the compaction cylinder 1, the threaded ring 1003 on the chassis 9 is sleeved on the lower end of the compaction cylinder 1, so that the chassis 9 and the lower end of the compaction cylinder 1 can be fixed together, so that when the soil compaction test is carried out in the compaction cylinder 1, the soil can be prevented from overflowing from the bottom of the compaction cylinder 1.
[0045] Embodiment three:
[0046] The fixing assembly 10 includes a magnet 1004, which is fixedly mounted on the upper side of the chassis 9. The upper side of the magnet 1004 is adjacent to the lower end of the compaction cylinder 1. When the chassis 9 is sleeved on the lower end of the compaction cylinder 1, the magnet 1004 adsorbs the chassis 9 and the lower end of the compaction cylinder 1 together, so that the chassis 9 can be quickly removed from the lower end of the compaction cylinder 1 after the compaction test of the soil in the compaction cylinder 1 is completed.
[0047] Working principle: When conducting a geotechnical compaction test, Figure 2 , Figure 3 and Figure 7 As shown, first, the chassis 9 is installed on the lower end of the compaction cylinder 1 through the fixing assembly 10, and then the compaction cylinder 1 and the chassis 9 are placed on the experimental table, and the first side 6 and the second side plate 7 are inserted into the multiple groups of slots 5 through the multiple groups of plug blocks 8, so that the first side 6 and the second side plate 7 can be fitted with the inner wall of the compaction cylinder 1, and then the sleeve 2 is inserted into the upper end of the compaction cylinder 1, and the screw and nut on the experimental table are inserted into the through hole 4 to fix the sleeve 2, so that after the soil compaction test in the compaction cylinder 1 is completed, the compaction cylinder 1 can be removed from the first The side plate 6 and the second side plate 7 are removed, and then the first side plate 6 and the second side plate 7 are separated, so that the soil that has completed the compaction test can be quickly separated. During the compaction test, the spring 14 is extended upward by pulling the measuring rod 13, and then the measuring rod 13 is rotated and moved on the fixed rod 11 through the rotating plate 12 in the compaction cylinder 1, and the measuring rod 13 is loosened. The measuring rod 13 is inserted into the compaction cylinder 1 under the action of the restoring elastic force of the spring 14, and the compaction height of the soil in the compaction cylinder 1 can be measured. The above is the entire working principle of the utility model.
