How the hook net is handled in quicksand. Plastic-coated mesh to inhibit the phenomenon of sand: excavation drainage, assuming direct surface drainage, the soil will be upward momentum, can produce the phenomenon of sand. Then the bottom dug earth gusher water, can not remove the deposition or other means, straight row 9 well point precipitation, precipitation of various methods of artificial way to drop the groundwater table well point precipitation, it not only adds the pressure gradient.
Can also change tendency of groundwater activity event, though there are many sedimentary method, engineering properties should be considered, the excavation depth, soil characteristics and economic and other elements in consideration, shallow foundation pit, less than 4 per cent shallow light well point of economy, deep foundation pit should consider radiation well point, large deep foundation pit precipitation should be considered, and the deep well point.
Comparison of irrigation Wells and light as well as various kinds of unsuitable schemes, it is acknowledged that the seepage curtain of the seepage curtain of the useful precipitation scheme is used to prevent or bind the groundwater seepage into the pit, and the use of hook flower mesh stone curtain; Sometimes it is also necessary to precipitation in the curtain or outside the water and soil mixing pile, continuous a circle of water and soil mixing pile, hanging net is a commonly used anti-seepage and water sealing structure, water and soil retaining wall can also carry forward the results, in the stalemate and sealing, bored pile, pile retaining soil, water and soil mixing pile water sealing.
The principle of the hook mesh is similar to the surface layer slope protection system such as spray anchor and soil nail wall. Features of the hook network system: its flexible characteristics can make the system will be part of the converge load to all around the uniform transfer to give full play to the protection of the whole system, that is, part of the load, the whole role, so that the hook network system can accept a larger load and reduce the single bolt anchorage force requirements.
