Abstract
The utility model discloses a big yield precipitation well plugging device belongs to precipitation well shutoff equipment technical field. Its technical scheme is a big yield precipitation well plugging device, including setting up the non -sand cement pipe on the former soil of basement, wherein the non -sand cement pipe top sets gradually seal ring I from bottom to top, vertical steel pipe, and interior stagnant water steel sheet and ring flange seal the circumference of vertical steel pipe sets gradually sand -gravel cushion and bottom plate concrete layer from bottom to top, sets up at bottom plate concrete layer to center on the waterproofing membrane layer and the ferrule of vertical steel pipe, the top of vertical steel pipe sets up seals the layer, lieing in in the former soil of sand -gravel cushion and basement be it 25 to set up the particle diameter in the vertical steel pipe 40mm's stone layer. The beneficial effects of the utility model are that: simple structure, the firm soil body of big yield precipitation well circumference makes the circumference of big yield precipitation well firm, and the shutoff is solid, has improved the stability of big yield precipitation well.
Description
Technical field
This utility model relates to plugging dewatering well equipment technical field, particularly to a kind of big yield plugging dewatering well device.
Background technology
Construction site is not also for the plugging device of big yield dewatering well at present, causes the soil body pine of dewatering well circumference to split, harm of running off and cave in when running into big yield by dewatering well.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of big yield plugging dewatering well device.
Invention thought of the present utility model is: first discharging the water in the above soil body in leakage point surrounding splash guard top；By connecting vertical steel pipe on former well casing, in making leakage point well, water level keeps static；In the case of not destroying former well casing structure, former discarded suction pump is extracted；By connecting vertical steel pipe top, utilize the tremie placing grouting material inserted at the bottom of pipe, pour absolute altitude and control in 26.00m position, close and weld former flange outer rim；After grouting material intensity reaches design requirement, the unnecessary vertical steel pipe in excision top, steel plate for sealing water in vertical steel pipe welded top；Digging out reserved well head surrounding soil, dabbing place where troops were originally stationed bottom plate top surface also implants reinforcing bar, and colligation increases the reinforcing bar at concrete cap position, and casting concrete newly.
A kind of big yield plugging dewatering well device, including the sand-free concrete tube being arranged on substrate original soil, wherein, at described sand-free concrete tube top, set gradually seal ring I, vertical steel pipe from bottom to top, interior steel plate for sealing water and ring flange sealing, circumference at described vertical steel pipe sets gradually sand-gravel cushion and underplate concrete layer from bottom to top, arranges the waterproof roll layer around described vertical steel pipe and pipe collar at institute's underplate concrete layer, and the top of described vertical steel pipe arranges sealing layer；
Described vertical steel pipe in being positioned at described sand-gravel cushion and substrate original soil arranges stone layer.
Along the circumference of described vertical steel pipe, reinforcing bar is set at described underplate concrete layer.
Described waterproof roll layer is that polyurethane water-proof paint is made.
Described sealing layer is that polyurethane is constituted.
The beneficial effects of the utility model are: simple in construction, the soil body of firm big yield dewatering well circumference, make the circumference of big yield dewatering well consolidate, block solid, improve the stability of big yield dewatering well.
