Abstract

The invention discloses a pre-disintegrating mudstone wetting deformation testing device achieving air tightness. The device comprises a loading system, a water and gas circulation system, a measurement system and a pressure chamber. The loading system is a pressure lever fixed to a base plate through two metal stand columns, the water and gas circulation system comprises a water inlet, a drain pipe and a vent pipe, the measurement system comprises a pressurized bar with scales and a water pressure sensor, the pressure chamber comprises an inner cylinder and an outer cylinder, the inner cylinder is composed of two semi-circular rings with drilled holes, the two semi-circular rings are fixed through nuts, and the outer cylinder and a cover plate are sealed through the base. The device has the advantages of being good in air tightness, convenient for sample loading, easy for measuring operation, accurate and reliable in test result and the like.

Description

technical field [0001] The invention belongs to the technical field of test devices, and relates to a simple test device for the wetting deformation of pre-disintegrated mudstone with airtightness. deformation characteristics. Background technique [0002] The concept of wetting deformation originated from water conservancy projects such as earth-rock dams. It refers to the fact that the earth-rock filling body is soaked in water under a certain stress state. Due to the softening and breaking of some particles in water and the contact of water-lubricated particles, the particles will slip, break and collide with each other. rearrangement, resulting in deformation and redistribution of stress in the soil. [0003] At present, my country's expressway and railway network are developing rapidly, and mudstone is widely distributed in the southern region. Highway construction will inevitably pass through the mudstone distribution area. In order to protect the environment and redu...
