Problems solved by technology

It can be seen that sample removal is time-consuming and labor-intensive, and injuries often occur during this process
In addition, MBT waste needs to be filled in layers when filling samples, and the current permeameter does not have a special compaction instrument, and the use of compaction instruments with mismatched sizes and manual compaction will lead to different compaction effects in various parts. Irregularities directly affect the accuracy of experimental results
Further, conventional water storage devices use horizontal adjustment rods and pins to adjust the water tank, and taking this way to control the height of the water head makes the accuracy very poor
This series of factors makes the MBT garbage infiltration test very complicated, and brings great uncertainties to the experimental results

Abstract

The invention discloses an MBT garbage permeameter with a compaction hammer and a convenient-to-move permeation column and an adjustable water head. The bottom of the permeation column is fixed with a water inlet disc, a water inlet of the water inlet disc is connected with a water outlet of the water storage device, and two threaded holes are formed in the water inlet disc; the two permeation column straight rods fixed at the top of the permeation column and the sliding track provided with the vertical track section form a rolling friction pair; two through holes are formed in the bottom of the end, away from the vertical track section, of the track frame, and track bottom bolts are inserted into the through holes. A compaction device is located at the upper position between the two bottom bolts; the bottom of the bearing frame and the lifting adjusting device are hinged to the lever at different positions. A gland assembly is fixed to the top of the bearing frame and located over the permeation column. The permeation column can be lifted and moved along the sliding track, and time and labor are saved during sample filling and dismounting; the compaction device freely falls to prepare a sample, so that the sample is uniform; the height of the fixed fulcrum of the lever is adjustable, so that the gland assembly can always compact the sample in the permeation column.

Description

technical field [0001] The invention belongs to the technical field of geotechnical tests, and in particular relates to an MBT garbage infiltration instrument with a compaction hammer, which is easy to move and has an adjustable water head, and a permeation column for measuring the relationship among compression, stress and infiltration of MBT garbage. Background technique [0002] With the acceleration of urbanization in China, many cities have been surrounded by garbage, and the treatment and volume reduction of garbage is imminent. Mechanical-biological treatment (Mechanical and Biological Treatment, MBT) has attracted people's attention as an advanced domestic waste treatment method. MBT can not only reduce the volume of waste, but also use methane generated after domestic waste treatment for power generation and heating . However, the relationship between the seepage fluid generated after MBT landfill and compression and stress is still a difficult engineering problem,...
