Description
Technical field
The utility model is related to dewatering wells, more specifically to a kind of plugging dewatering well device.
Background technology
The deep foundation pit precipitation of building trade is more scabrous problem, currently, some deeper foundation pits, have underground water and
Rivers water system is abundant, dewatering well pours in that water is big, fireballing feature, blocks and bad generates piping and stream easily at well point
Sand generates destructive harm to foundation pit.The method for blocking used at present is to propose dewatering well after underplate concrete has been constructed
Suction pump, coarse sand, clay ball etc. in rapid back-filling in layers soil, underground flood peak is pushed down, the extra of bottom plate is and then will be above
After well casing excision, with dry cement back pressure well casing, then steel plate soldering and sealing well casing is used, and use high-strength grout is filled to base surface.The party
Complexity is cumbersome in method practical operation, it is long to expend the time, and, shove fireballing Project Realization big especially for the underground water amount of gushing is sealed
Stifled effect is bad.
Invention content
The technical problem to be solved by the present invention is to provide a kind of plugging dewatering well device, solve deep basal pit drop
Well pours in that water is big, fireballing feature, blocks the bad problem that piping and quicksand are generated easily at well point.
Technical solution adopted by the utility model to solve its technical problems is：A kind of plugging dewatering well device is constructed, is wrapped
