Description

A kind of equipment by decompression drainage quick blocking precipitation pipe well
Technical field
The utility model relates to a kind of equipment by decompression drainage quick blocking precipitation pipe well.
Background technology
Foundation pit dewater design generally adopts " sand-free concrete tube " tube well dewatering, the shutoff that its General Requirements Main Underground body structure completes or agent structure carries out precipitation pipe well again after binding on the ground, simultaneously, well domestic demand backfill sandstone during shutoff, the steel plate supporting plate welding required operation deadline of conventional design precipitation pipe well shutoff needs 20 ~ 30 minutes, more cannot to complete before the shutoff of precipitation pipe well sandstone backfilling working in well.
Summary of the invention
The utility model provides a kind of equipment by decompression drainage quick blocking precipitation pipe well for the deficiencies in the prior art, object needs 20 ~ 30 minutes at the steel plate supporting plate welding required operation deadline solving the shutoff of conventional design precipitation pipe well, more cannot complete the technical problem of sandstone backfilling working in well before the shutoff of precipitation pipe well.
The utility model is for realizing above object, adopt following scheme: a kind of equipment by decompression drainage quick blocking precipitation pipe well, comprise non-fine concrete downcomer and sleeve pipe, described cannula tip is provided with cover plate, described sleeve outer wall is provided with water-proof wing-ring, described sleeve outer wall bottom even distributes four anchor pin, described sleeve bottom socket non-fine concrete downcomer top, described sleeve pipe is cylindrical steel pipe box, its inwall is provided with supporting plate, described supporting plate center is evenly provided with 2 or 3 circular holes, described circular hole is welded with internal thread short piece.
Preferably, described internal thread short piece is steel hollow section, and its screw top spins blocking cap.
The beneficial effects of the utility model: the utility model structure is simple, rational in infrastructure, easy-to-use, supporting plate arranges the conduction hole and batching hole that are made up of circular hole and outer silk short piece, by drainage, effectively control water level elevation in precipitation pipe well, ensure supporting plate welding required time.
Accompanying drawing explanation
Fig. 1 is the utility model section of structure;
Fig. 2 is the utility model supporting plate and outer silk short piece welding figure;
Fig. 3 is the utility model support board structure schematic diagram;
Fig. 4 is the outer silk short piece structural representation of the utility model.
Detailed description of the invention
A kind of equipment by decompression drainage quick blocking precipitation pipe well as illustrated in the drawing, comprise non-fine concrete downcomer and sleeve pipe 1, described sleeve pipe 1 top is provided with cover plate 2, described sleeve pipe 1 outer wall is provided with water-proof wing-ring 3, described sleeve pipe 1 outer wall bottom even distributes four anchor pin 8, non-fine concrete downcomer top is socketed bottom described sleeve pipe 1, it is characterized in that, described sleeve pipe 1 is cylindrical steel pipe box, its inwall is provided with supporting plate 4, described supporting plate 4 center is evenly provided with 2 or 3 circular holes 5, described circular hole 5 is welded with internal thread short piece 6, described internal thread short piece 6 is steel hollow section, its screw top spins blocking cap 7.
Embodiment, the making of supporting plate: water-proof wing-ring 3 cuts and forms on a monoblock steel plate, the disk of its middle cut away, as supporting plate 4, carries out even punching to supporting plate 4 center, and weld internal thread short piece 6 respectively on supporting plate hole; Wherein first carry out shutoff 4/5 non-fine concrete downcomer make " holes supporting plate ", after carry out shutoff 1/5 non-fine concrete downcomer make " 3 hole steel plate supporting plate ", during 2 supporting plate holes, one is done conduction hole, and another does batching hole, during 3 hole, drainage is done in two holes, and a hole feeds intake;
The installation of supporting plate: the installation carrying out supporting plate 4 after self priming pump installs, supporting plate 4 keeps flat and is arranged in sleeve pipe 1, supporting plate 4 surrounding and sleeve pipe 1 gap weldig, after having welded, the internal thread short piece 6 of conduction hole is wrapped with unsintered tape;
The installation of blocking cap: after sand refills and completes into, first carries out shutoff to batching hole, and silk short piece 6 mouth places are wrapped with unsintered tape outside, then by using blocking cap 7 to be screwed in outer silk short piece 6; During the shutoff of conduction hole, first the suction water pipe of self priming pump is extracted, silk short piece 6 mouth places are wrapped with unsintered tape outside, then by using blocking cap 7 to be screwed in outer silk short piece 6, if conduction hole has water to overflow, then the sponge block of the suitable size of the interior filling of silk short piece 6 outside, when guaranteeing in pipe well, water sand mixture to gush, only have water to release, release without sand), complete " blocking cap " and install.
