About hook mesh think we are now very understand, so tell us what is the role of hook mesh in the field of application. Today to tell us about hook net in quicksand is how to deal with. Plastic coated hook mesh to inhibit sand flow phenomenon: excavation drainage, assuming direct surface drainage, soil will be up the power, can produce sand flow phenomenon. Then the bottom of the earth gushing water, can not remove the deposition or other methods, straight row 9 well point precipitation, precipitation of all kinds of artificial way to lower the groundwater table well point precipitation, it not only adds 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.
The comparison of irrigation well and light and all kinds of unsuitable schemes, admit that the seepage curtain of the seepage curtain of the useful precipitation scheme, used to prevent or constrain his groundwater seepage into the pit, the use of hook stone curtain; Sometimes also need in the curtain or outside of the water soil mixing pile, a circle of water soil mixing pile, hook net is a commonly used waterproof structure, water soil retaining wall can also carry forward the results, in the holding and sealing, bored pile, pile retaining, water soil mixing pile sealing.
The function principle of hook mesh is similar to the slope protection system of spray anchor and soil nail wall. Hook mesh system characteristics: its flexible characteristics can make the system will be part of the uniform transfer of load around to give full play to the protection of the whole system, that is, part of the load, all the role, so that the hook mesh system can accept a larger load and reduce the anchorage force requirements of a single bolt.
