Description

A New Surface Vibration Compactor

technical field

The utility model relates to the technical field of indoor geotechnical test equipment, in particular to a novel surface vibration compactor.

Background technique

The surface vibration compaction test is an important soil engineering test. The surface vibration compaction test can obtain the maximum compactness that the soil sample can achieve after receiving the vibration compaction of a fixed frequency on the surface. The test was carried out with a surface vibratory compactor equipped with vibrating hammers and sample barrels of two different sizes, which can be used to vibrate soil samples with two different gradations of thickness and fineness respectively. However, since the diameter of the vibrating hammer is slightly smaller than the inner diameter of the sample barrel, many fine particles often escape through the gap between the two during the test. When the moisture content of the soil sample is small, the escaping soil particles are easily in Diffusion in the air will cause environmental pollution and endanger the health of test personnel. Moreover, for some tests that need to compare the gradation changes of soil samples before and after compaction, the continuous escape of fine particles will inevitably lead to a decrease in the total mass of the soil sample and the content of fine particles after the test. From the perspective of ensuring the reliability of the test results, it is necessary to consider Collection of escaping fine particles is necessary. In addition, since the bottom of the sample barrel is on the same level as the upper surface of the vibrator base, the vibration power of the vibrator is relatively large, and it often occurs that the sample barrel deviates horizontally to a certain side during the vibration process, which cannot effectively control The sample bucket is fixed. Moreover, after the test, it is necessary to measure the distance from the soil surface in the barrel to the mouth of the barrel, so as to convert the volume of the soil in the barrel. However, there is no corresponding setting in the sample barrels circulating in the market today, and the operation is inconvenient.

The vibrating hammer connecting part 6 is fixed on the lower end of the connecting rod 4. The vibrating hammer connecting part 6 is connected with the large vibrating hammer or The small vibrating hammer 4 is connected.

The large sample bucket includes a large sample bucket base, a large sample bucket body and an upper fixing ring A. The inner wall of the large sample bucket body is provided with 8 scale lines A along the axial direction, and the 8 scale lines A are along the large sample bucket body. Evenly distributed in the circumferential direction, the 0 scales of the eight scale lines A are all located at the mouth of the large sample barrel.

The measuring ranges of scale line A and scale line B14 are the barrel depths of the large sample barrel and small sample barrel 2 respectively, and the division value is 1mm. The scale lines are marked with white paint that is significantly different from the color of the sample barrel. The purpose of setting 8 scale lines evenly along the circumference of the sample barrel is to obtain the distance from the mouth of the sample barrel at different positions on the sample surface after the test is over, and take the average value of the readings on the 8 scale lines It is the final value involved in the calculation.

As shown in Figure 3, a large groove 12 and a small groove 13 are provided in the center of the vibrator base 1, the large groove 12 is the same shape and size as the large sample bucket base, and the small groove 13 is the same as the small sample bucket base. 8 have the same shape and size, and the axes of the large groove and the small groove coincide. The effect of setting the size (diameter and depth) of the groove to be the same as the size of the sample bucket base has two aspects: on the one hand, the diameter of the groove is the same as the diameter of the sample bucket base, and the side wall of the groove will be opposite to the sample bucket. It plays a fixed role to prevent the sample barrel from laterally shifting during the vibration process; after placing the large sample barrel in the large groove, the top surface of the base of the large sample bucket is aligned with the top surface of the vibrator base After the small sample bucket is placed in the small groove, the top surface of the base of the small sample bucket is flush with the bottom of the large groove, so that it is convenient to use the fixing parts to fix the sample bucket again.

As shown in FIG. 4 , the sample barrel fixture includes three pressing blocks 15 and three bolts 16 . The briquetting block is an elongated metal block with an oblong hole in the center, and the size of the oblong hole is greater than the size of the threaded rod in the bolt 16 and smaller than the size of the nut of the bolt 16 .

The inner diameter of the connecting ring sleeve 7 of the dust cover is the same as that of the connecting rod 4, and its material is aluminum alloy. The aluminum alloy is selected because the aluminum alloy is light and hard, which is easy to fix, and will not affect the vibration machine due to excessive mass. power. As shown in FIG. 1 , the dust cover connecting ring 7 is fixedly fitted on the connecting rod 4 , and the dust cover connecting ring 7 is located between the vibrator 5 and the vibrating hammer connecting piece 6 . As shown in FIG. 5 , an annular groove 11 is formed on the side wall of the dust cover connecting ring 7 along the circumferential direction.

The method of using the novel surface vibration compactor provided by the utility model is as follows:

When the vibration compaction test needs to use a small sample barrel and a small vibrating hammer, as shown in Figure 1 and Figure 4, first install the small vibrating hammer 3 on the vibrating hammer connector 6, and then install the small sample barrel base 8 Place it in the small groove 13 of the vibrating instrument base 1, and then fix three pressing blocks 15 on the vibrating instrument base 1 through bolts 16, and at the same time make the three pressing blocks 15 press the small sample bucket base 8, thereby Firmly fix the small sample bucket to the base of the vibrator.

When the vibration compaction test needs to use a large sample barrel and a large vibrating hammer, first install the large vibrating hammer on the connecting piece of the vibrating hammer, and then place the base of the large sample barrel in the large groove of the vibrator base, Then fix the three pressing blocks on the base of the vibrating instrument through bolts, and at the same time make the three pressing blocks press the base of the large sample bucket, thereby firmly fixing the large sample bucket on the base of the vibrating instrument.

During the test, an annular plastic film with openings at both ends can be used to cover the outside of the vibrating hammer and the sample barrel, the upper open end of the film is tied in the groove of the connecting ring of the dust cover, and the lower open end is tied to the test chamber. The junction of the fixed ring on the upper part of the sample barrel and the body of the sample barrel can effectively avoid the environmental pollution caused by the escape of fine particles; when it is necessary to collect the escaped particles, the annular plastic film can be removed after the test and used The brush collects the fine particles scattered in the coverage of the film, which effectively improves the test accuracy.

After the test, read the scale values directly from the 8 scale lines on the inner wall of the sample barrel, and take the average value as the final distance from the sample surface to the mouth of the sample barrel to participate in subsequent calculations.
