Abstract

The invention discloses a porous medium penetration slip-casting multi-parameter monitoring device and a test method thereof. The monitoring device comprises a slip-casting apparatus, which his connected to an inlet cabin. The inlet cabin is connected to one end of a connection steel pipe through connecting pieces, and the other end of the steel pipe is connected to an outlet cabin through connecting pieces. A joint position of the inlet cabin and the steel pipe and a joint position of the outlet cabin and the steel pipe are both provided with filter plates. The steel pipe is provided with a press measuring device. Slurry discharge pipes are connected at the bottom of the steel pipe, and a volume measuring apparatus is disposed below each slurry discharge pipe and positioned above a weighing apparatus. The filter plate of the outlet cabin is connected with a screw, and the screw is provided with a lower packing box. The outlet cabin is equipped with a flow measuring apparatus. The monitoring device helps to solve the problem of monitoring key parameters during porous medium penetration slip-casting. Compared with conventional research, the monitoring device has the advantages that various parameters can be monitored, the monitoring precision is high, the boundary effect of the device can be eliminated, and the device is adjustable in dimension and simple to operate.

Description

technical field [0001] The invention relates to a porous medium permeation grouting multi-parameter monitoring device and a test method thereof. Background technique [0002] With the in-depth development of my country's infrastructure construction, there are more and more underground engineering projects, and the geological conditions are becoming more and more complex. Among them, the weak sandy soil layer has become a common unfavorable geological problem due to its loose and broken structure, poor self-supporting capacity, and strong water richness, which seriously affects the construction and operation of underground projects. [0003] As a relatively mature technical means, the grouting method has been widely used and developed in various fields. The core problem of using grouting method to treat weak sandy soil layer is the effective diffusion and filling of grout. Since the permeability coefficient of pore medium is generally small, higher requirements are put forwa...
