[0002] The compaction instrument is an essential testing equipment in highway, tunnel, hydropower, railway and municipal engineering projects. It is mainly used to measure the relationship between soil moisture content and dry density, determine the optimal moisture content and maximum dry density of soil samples, and judge the compaction performance of soil. During the compaction test, a compaction hammer is required to compact each layer of soil sample multiple times and ensure that each layer of soil sample is compacted evenly, thereby ensuring the accuracy of the compaction test results. At present, during the operation, the inspector subjectively determines the falling position of each compaction hammer, resulting in over-compaction of some parts of the soil sample and under-compaction of some parts. In addition, when the inspector manually supports the outer cylinder of the compaction hammer, the soil sample will be compacted unevenly due to the tilted fall of the compaction hammer. As a result, the compaction test results deviate from the actual situation.
[0003] Therefore, how to ensure that all positions of the soil sample are evenly compressed during the compaction process is a technical problem that technical personnel in this field currently need to solve. Summary of the invention

DETAILED DESCRIPTION
[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0026] In the following description, specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] (I) Auxiliary device for manual compaction instrument, please refer to Figure 5 The manual compaction instrument comprises a base 16, on which a compaction cylinder 15 is arranged, inside which a compaction hammer 13 is arranged, and the compaction hammer 13 is longitudinally sleeved with a compaction hammer guide cylinder 14. The auxiliary device of the manual compaction instrument comprises a positioning assembly, a clamping assembly and a support rod 10; the positioning assembly comprises a first cylinder 1, on the upper surface of which an angle dividing plate 2 is arranged, and on the inner surface of which a transverse T-shaped sliding groove 5 along the circumferential rotation direction is arranged.
[0028] For further reference, Figure 1 and Figure 2 The clamping assembly includes a second cylinder 6 and two arc clamping plates 7; the inner diameter of the arc clamping plate 7 matches the outer diameter of the hammer guide cylinder 14; the outer surface of the second cylinder 6 is provided with a T-shaped slider 8 matching the T-shaped sliding groove 5, and the T-shaped slider 8 can move freely in the plane where the T-shaped sliding groove 5 is located, and the second cylinder 6 is provided with two threaded holes with the center line passing through the diameter, and the two arc clamping plates 7 are respectively connected to the inner side of the second cylinder 6 by bolts 9, and the adjusting bolts 9 can make the two arc plates 7 move relatively close to each other, so as to ensure that the two arc plates 7 are firmly clamped with the hammer guide cylinder 14.
[0029] For further reference, Figure 5 The support rod 10 is used to connect with the base 16 to ensure that the positioning assembly is directly above the base and the connection is firm, thereby ensuring the uniformity of compaction.
[0030] For further reference, Figure 1 and Figure 3 The first cylinder 1 is provided with screw rods 4 on the outer surfaces on the left and right sides respectively. There are two support rods 10, and the two support rods 10 are connected to the screw rods 4 through threaded sleeves 12, which further ensures the stability and reliability of the device.
[0031] For further reference, Figure 1 and Figure 2 A level 3 is provided on the outer surfaces of the front and rear sides of the first cylinder 1, and the direction of the level 3 is perpendicular to the direction of the screw 4.
[0032] Furthermore, the level 3 is a bubble level, which is intuitive and simple to use, and by adjusting the bubble level to make the bubble of the bubble level in the center, the positioning device is ensured to be in a horizontal state, thereby ensuring that the compacting hammer falls vertically during the compacting process.
[0033] For further reference, Figure 3 The angle precision of the angle dividing plate 2 is 10 degrees, and in practice, the precision can also be set to 1 degree. It can provide a reference for determining the falling position of each hammer strike, avoiding overpressure at some positions of the soil sample and underpressure at other positions, thereby ensuring that the soil sample is evenly compressed.
[0034] For further reference, Figure 2 A plurality of springs 11 are arranged between the second cylinder 6 and the two arc clamping pieces 7, and the bolt 9 is rotatably connected to the two arc clamping pieces 7. In practice, four springs are used on each side in this embodiment. The buffer between the springs can reduce the pressure between the arc clamping piece 7 and the second cylinder 6, thereby ensuring the stability of the clamping.
[0035] For further reference, Figure 5 , the inner diameter of the first cylinder 1 is R1, the inner diameter of the compacting cylinder 15 is R2, the inner diameter of the compacting hammer 13 is R3, R1 is equal to R2, and R3 is half of R2. By setting the inner diameter of the first cylinder equal to the inner diameter of the compacting cylinder, the compacting hammer can compact to the edge of the soil sample, ensuring that any position of the soil sample can be compacted.
[0036] (II) Reference Figure 5 The manual compactor capable of locating the compaction position is connected to the manual compactor auxiliary device.
[0037] Furthermore, a stabilizing plate 17 is provided between each support rod 10 and the compacting cylinder 15 of the manual compactor to ensure the firmness and stability of the overall structure.
[0038] In the above embodiment, the steps for using the auxiliary device of the manual compactor are as follows:
[0039] The first step is to connect the positioning assembly to the support rod through a threaded sleeve;
[0040] In the second step, the T-shaped slide block is embedded in the T-shaped sliding groove of the positioning assembly, and the support rod is connected to the base, so that the auxiliary device of the manual compaction instrument is located directly above the compaction instrument;
[0041] The third step is to adjust the bolts of the clamping assembly so that the two arc plates are relatively close to each other and move to clamp the hammer guide cylinder;
[0042] The fourth step is to adjust the positioning assembly so that the bubble of the bubble level is at the center of the bubble level, ensuring that the positioning assembly is in a horizontal state, thereby ensuring that the compacting hammer is in a vertical state during the compacting process;
[0043] Step 5: Refer to the angle scale reading of the positioning assembly to ensure that the compacting hammer drops at the same angle each time. For example, when the soil sample needs to be compacted 18 times, the compacting hammer should be released every 20° according to the angle scale reading to ensure uniform compaction at all positions of the soil sample.
[0044] Although the present invention has been described in detail in this specification by means of general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto on the basis of the present invention. Therefore, these modifications or improvements made without departing from the present invention all fall within the scope of protection claimed by the present invention.
