Stabilizing method of decomposing classifier tank basic in backfilling earth and structure thereof

Abstract

The invention discloses an antihunt means of dissociation grading tank base in backfill soil and structure, which is characterized by the following: substituting pile type structure base with box type individual base; increasing touched area of the base and bearing stratum under nature floor; improving stability of the dissociation grading tank base; setting the middle of the box type individual base as hollow; decreasing the quantities of the backfill soil; setting the structure as box type individual base poured with steel concrete; comprising plan base (2); touching with earth surface bearing stratum (1); arranging one or above one back plate (3)on the plan base (2); forming cavity between the back plate (3); arranging foundation pace (5)upper the back plate (3). This invention can intensify stability and safety of dissociation grading tank base and can shorten construction period.

Description

technical field [0001] The invention relates to a foundation construction method and structure, in particular to a method and structure for stabilizing the decomposition and classification groove foundation in the backfill soil of an alumina factory. Background technique [0002] The decomposition and grading process of alumina needs to build two or more decomposition and grading tanks on the floor with a length of 300 meters, a width of 40 meters and a slope of 3%. The first-level operating surface is 9 meters above the natural ground, and now the foundation of the decomposition and grading tank is generally designed as a pile type, such as image 3 , Figure 4 As shown, the concrete pile 9 as the main support will be poured with reinforced concrete from the bearing layer 1 below the natural ground 6 to keep the stability of the foundation, and the part above the natural ground will be filled with backfill soil 8 to be flush with the foundation surface. The highest level o...

Problems solved by technology

When the bearing layer 1 is shallower than the natural ground 6 and the backfill 8 is deep, most of the pile body is in the backfill area, and the backfill is relatively loose, and because the ground has a 3% slope 7 and the upper part of the decomposition and classification groove The load of the pile is relatively large, and the lateral stability of the pile body in the backfill soil is poor, and there are certain safety hazards

In addition, a large amount of backfill soil needs to be filled in the gaps between the piles under the decomposed graded groove foundation, which will take a long time and will also affect the construction period of the project.
