Description

Integrated soil body module manufacturing device

Technical Field

The invention belongs to the technical field of geotechnical tests, and particularly relates to an integrated soil body module manufacturing device.

Background

In the current geotechnical test, the soil mass module is not only used for measuring the water content of the soil mass, but also can be applied to various aspects such as soil mass salt swelling, subsidence and the like. However, the existing geotechnical test module manufacturing instrument has single specification, so that a required module test piece cannot be manufactured accurately and efficiently. On the basis of the water and soil mixing device, a tester can stir and mix water and soil manually, but the water and soil at each place cannot be uniformly mixed due to manual errors and the like, so that a certain error is generated in the test.

At present, in the geotechnical test, in the proportioning process of most of test soil, errors are easily generated by manually proportioning water and soil, so that the water in the soil cannot be fully stirred; meanwhile, the compaction device is not only used for measuring the water content of the soil body in the compaction process, but also widely applied to a salt leaching test and a salt swelling test of the salty soil. However, the existing 5KG standard manual light compaction instrument and hydraulic vibration compaction instrument can not compact the salted soil in the material containing barrel. The 5KG standard manual light compaction device is characterized in that a solid hammer in the compaction device is manually pulled up, so that the compaction device can freely fall to the ground to compact soil in a cylinder wall through self gravity, the compaction times of the soil in each layer of the compaction device are 25 times when the soil is required to be divided into three times in the test process, the method is simple to operate, errors caused by personnel operation in the test process cannot be avoided, the compaction degree of the soil at the same interface in the compaction process is inconsistent, and a certain test error is caused. Another hydraulic vibratory compactor is a heavy compaction machine in which a pattern of 4-10kg is divided into 5 layers, each layer being 56 hits, and if divided into 3 layers, each layer being 94 hits. The hydraulic vibration compaction instrument can effectively avoid the problem of different compaction degrees of the same soil layer caused by manual operation in the compaction process, but has a certain specification of the vibration compaction platform, larger compaction weight, ideal consolidation effect of cylinder walls with different specifications and weaker hardness under compaction, and higher price of the hydraulic vibration compaction instrument, which is difficult to bear in a common laboratory. Therefore, it is important to find a compact instrument that is simple, reasonable and efficient.

A large number of experiments prove that when an indoor civil engineering experiment is carried out, the manual compaction error is one of main factors causing the experiment error, and then a certain data error is caused in the subsequent experiment.

At present, an indoor geotechnical test compaction device mainly adopts a 5KG standard manual light compaction device and a hydraulic vibration compaction device, but the compaction device and the hydraulic vibration compaction device have obvious defects. The 5KG standard manual light compaction device can not achieve even compaction effect on soil in the compaction process due to manual operation, and can not achieve even stress effect at each point in the descending compaction process due to the fact that the compaction hammer is required to be lifted manually. The other method is to fix the compaction cylinder on the hydraulic vibration compaction instrument and to compact the soil structure through the hydraulic hammer on the hydraulic vibration compaction instrument, but the equipment has a certain limitation in the process of testing in different places due to high price and large volume, and can not perform test work in the field and other conditions.

When the gear teeth of the semicircular conical gear 23 are meshed with the gear teeth of the duplex gear 26, the gear teeth of the semicircular conical gear 23 are separated from the gear teeth of the duplex gear 26 at the other end, the lifting column 27 is lifted to the highest point at the moment, and then the lifting column 27 moves downwards under the action of gravity, so that the compaction effect is achieved. Since there is a phase difference of 90 degrees between the duplex gears 26, when the semicircular transmission gear contacts the duplex gears 26, the right elevating column 27 of the gear is in an elevated state, and the opposite elevating column 27 is elevated to the top end and then in a lowered state. When the movement between the lifting columns 27 is a cyclic movement, the four lifting columns 27 are driven by the semicircular bevel gears 23 to lift up in sequence to perform compaction movement on the ground. By varying the mass of lifting column 27 and compaction hammer 30, the soil in compaction drum 34 can be compacted with accuracy.

And the lower cylinder cover 302 is opened and evenly distributed in the compaction cylinder 34 during the ascending of the compaction hammer 30. One section of steel wire 303 in the compaction hammer 30 is connected with the opening of the lower cylinder cover 302, the other end of the steel wire 303 is connected with the edge of the feed inlet 25 at the top of the upper supporting sleeve 31, when the compaction hammer 30 is positioned at the bottom of the compaction cylinder 34, the steel wire 303 is in a straightened state, the lower cylinder cover is closed tightly, when the compaction hammer 30 is lifted, the steel wire 303 is loosened, the lower cylinder cover 302 can be opened in the lifting process of the compaction hammer 30, and experimental soil body fully vibrated in the compaction cylinder 34 is poured. Meanwhile, the compaction hammer 30 is made of steel, so that the overall mass of a compaction system can be fully increased, and the phenomenon of overturning of the equipment caused by overlarge mass of upper materials can be prevented, so that safety accidents can be prevented.

The integrated soil body module manufacturing device comprises the following steps:

preparing a test piece: the compaction drum 34 used in the test is a cylindrical cylinder with a geometric dimension of phi 152mm x 152mm, and is used for preparing soil materials with maximum dry density and optimal water content determined by the indoor compaction test and then preparing test pieces by adopting a static compaction method. A representative soil sample with natural water content of 20kg (heavy weight of 50 kg) is taken, crushed, screened by a 5mm sieve (heavy weight of 20mm or 40 mm), the screened soil sample is uniformly mixed, and the natural water content of the soil sample is measured. According to the plastic limit of the soil sample, the optimal water content is estimated, at least 5 soil samples with water content are selected, and the soil samples with natural water content are respectively air-dried or water-added for preparation, so that the water content of the prepared soil samples is uniformly distributed.

And (3) equipment control: firstly, the compaction cylinder 34 is fixed with the base, the prepared soil body is poured into the compaction cylinder 34 through the top feed inlet 25 of the upper supporting sleeve 31 three times, then the transitional steel ring is sleeved on the compaction cylinder 34, and the upper supporting sleeve 31 is arranged on the compaction cylinder 34, so that vibration is reduced.

When the semicircular bevel gear 23 leaves the lifting column 27, the lifting column 27 loses braking and descends, the soil is hammered by the compaction hammer 30 connected with the compaction hammer 30 through the fixing screw, and the compaction hammer 30 is lifted up to compact the soil 27 times. The heights of the samples of each layer are preferably equal, and the soil surface at the junction of the two layers should be shaved. At the completion of compaction, the height of the sample above the top of the compaction drum 34 should be less than 6mm.
