| titleOfInvention | A kind of dewatering well that can be separated with well casing looks for middle environmental protecting device |
| abstract | It the utility model is related to a kind of dewatering well that can be separated with well casing and look for middle environmental protecting device, it is characterised in that：At least three are arranged outside downcast well pipe and looks for middle structure, described at least three look for middle structure setting in the different height of filter correspondence position；Described to look for middle structure to have at least three bulge-structures, each bulge-structure is vertically arranged, and is evenly arranged in around well casing；At the radial protrusion maximum position of the bulge-structure, apart from being smaller than or equal to the gap between well casing and dewatering well perforate for well casing outer wall.The utility model dewatering well looks for middle environmental protecting device dewatering well perforate accurate, and aperture can be without excessive；After dewatering well perforate, well casing can be properly inserted the centre of perforate, and centering is accurate, look for middle structure to be made up of environmental-protecting material, and well casing can remove from dewatering well.Filtrate, sealing material, the dispensing substep that bankets are uniform, improve construction quality and property easy for construction. |
