Description
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 body module is not only used for measuring the water content of the soil body, but also can be applied to various aspects such as soil body salt swelling, dissolution and sinking and the like. However, the existing geotechnical test module manufacturing instrument has a single specification, so that the required module test piece cannot be accurately and efficiently manufactured. On the basis, the testing personnel stir and the water and soil are matched, but due to manual errors and other reasons, the uniform proportion of water and soil at each position cannot be achieved, and a certain error is generated in the test.
At present, in the soil engineering test, errors are easily generated in the process of proportioning most of soil for the test by manpower, so that the water in the soil body cannot be fully stirred; meanwhile, the compaction instrument is not only used for measuring the water content of the soil body in the compaction process, but also has wide application in a dissolution test and a salt swelling test of the saline soil. But the existing 5KG standard manual light compaction instrument and hydraulic vibration compaction instrument can not compact the saline soil body in the material containing barrel. The 5KG standard manual light compaction instrument is pulled up by a solid iron hammer in the compaction instrument manually, so that the soil in the cylinder wall is compacted by freely falling through the self gravity, in the test process, the compaction times of compacting each layer of the soil are 25 times by dividing the soil into three times, the method is simple to operate, and the inconsistency of the soil compaction degrees of the same interface in the compaction process due to the error caused by personnel operation in the test process can not be avoided, so that certain test errors are caused. Another type of hydraulic vibrocompactor is a heavy duty compactor, in which the pattern is divided into 5 layers of 4-10kg, each layer 56 is struck, and in the case of 3 layers, each layer 94 is struck. The hydraulic vibration compactor can effectively avoid the error problem of different compaction degrees of the same soil layer caused by manual operation in the compaction process, but because the vibration compaction table has certain specification and large compaction weight, the cylinder walls with different specifications and weaker hardness achieve ideal consolidation effect in the compaction process, and meanwhile, the hydraulic vibration compactor is expensive and cannot be born in a common laboratory. Therefore, it is important to find a simple, reasonable and efficient compaction device.
A large number of tests prove that when indoor civil engineering tests are carried out, manual compaction errors are one of main factors causing test errors, and certain data errors are caused in the subsequent tests.
At present, the indoor soil test compaction instrument mainly adopts a 5KG standard manual light compaction instrument and a hydraulic vibration compaction instrument, but the instruments have obvious defects. The 5KG standard manual light compaction instrument can not achieve the uniform compaction effect on the soil body in the compaction process due to manual operation, and meanwhile, the compaction hammer can not achieve the uniform stress effect at each point in the descending compaction process due to the fact that the compaction hammer needs to be lifted manually. The other method is that the compaction cylinder is fixed on a hydraulic vibration compactor, and a hydraulic hammer on the hydraulic vibration compactor is used for compacting the soil body structure, but the equipment has high price and large volume, so that the device has certain limitation when being tested in different places, and cannot be used for testing in the field and other conditions.
