Backfill regional waterproof structure of suffering from
Technical Field
The utility model relates to a backfill regional waterproof structure of suffering belongs to the deep foundation and backfills fertile groove region and low-lying hollow ground high backfill technical field.
Background
The deep foundation backfill fertilizer groove area refers to a space between a foundation outer wall or a basement outer wall and a foundation pit edge during foundation construction; the high backfill region of the low-lying hollow land refers to a storage yard region of construction waste for urban construction or excavation of various earth and stones for urban construction and a region of the low-lying hollow land which needs to be backfilled due to construction and the like.
The deep foundation backfill fertilizer tank region is required to be carried out according to design and related standard requirements during backfill construction, but if the factors of non-standard construction process, unqualified backfill materials, rich underground water in the fertilizer tank region, connection ways between the fertilizer tank region and surface water bodies and the like exist, the fertilizer tank region can form a rich water region with rich water along with the lapse of time, so that high water pressure can be generated on a foundation outer wall or a basement outer wall, the high water pressure can also be used as a supply source of underground water in a foundation slab region, accidents such as cracking and water seepage of the basement outer wall and the basement bottom slab are caused, and the safety and the use of a building are seriously influenced.
In addition, although the backfill materials in the high backfill region of the low-lying hollow land are diversified and compacted, the porosity and the permeability of the backfill region are large due to the diversity of particle sizes and types, so that the backfill region can form a water-rich or water-saturated region over time, the buildings and structures adjacent to the hollow land can be influenced, the hydrogeological characteristics of the hollow land and the periphery of the hollow land can be influenced and changed, and certain adverse effects can be caused.
The influence of water on the foundation in the foundation fertilizer tank area is generally treated by increasing the strength of a shear wall and drilling anchor rods on a basement bottom plate. If the basement is not treated during the foundation construction or the treatment process cannot meet the requirements, the basement bottom plate or the shear wall may crack, seep water or gush water. When water seepage and water burst occur, the treatment mode is to either make anti-floating and foundation again or to implement the pipe well precipitation project. In either method, the cost is high. At present, most of low-lying hollow backfill areas are filled with water and rich water, and a few areas are solved by a pipe well pumping mode in the later period, so that the cost is high.
Therefore, a backfill region waterproof structure with low cost and no damage to the original engineering is urgently needed in the prior art.
