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.
