Eyeholes are formed in the barrel wall of the lower barrel all around, a cylindrical filter screen is mounted in the lower barrel, an upper cross guide plate and a lower cross guide plate are horizontally arranged near the barrel bottom and the upper port of the lower barrel, each end of the upper guide plate and the lower guide plate is connected with the inner wall of the lower barrel, two holes are formed in crossed positions, a vertical guide rod penetrates through the two holes loosely, the upper end of the rod is connected with a horizontal water sealing cover plate, the filter material is buried under a trench bottom lining layer, the lower barrel is embedded into the filter material, the upper barrel is located above the trench bottom lining layer, and a horizontal sealing coat is laid surrounding the upper port of the outer wall of the lower barrel by a circle. The controllable non-return drainer can be opened and closed automatically according to water level and water pressure of an underground water accumulation layer, drains automatically and is simple in structure and high in practicality.
Description
Technical field
Controlled inverse-stopping type water trap of the present utility model belongs to the water conservancy project field, relates in particular to a kind of apparatus for draining subsurface water.
Background technology
When phreatic high building or canal for water conveyance ground are aquitard, underground water can not smooth and easy drainage and is produced osmotic pressure, when building surface infrastructure or canal for water conveyance liner structure deadweight during less than osmotic pressure, the phenomenon that it produces the distortion protuberance is referred to as water swelling.At this moment, need to discharge the ponding in the water layer, generally be in this layer bottom gutter and collecting well to be set, extract ground out with water pump, can cause the increasing of high water level displacement or canal for water conveyance to strengthen to underground osmotic pressure again, and limited by the geographical conditions of ponding layer, and construction, the draining cost is higher, and not easy care easily blocks up.The existing method that bottom building ground line or canal for water conveyance, installs the inverse-stopping type water trap additional that adopts more, because this water trap adopts hyoplastron or the draining of water seal control check more, easy care not after the installation, easily stopped up by the silt foreign material and ineffective, and can't regulate the pressure of underground water layer, effect is unsatisfactory.
Summary of the invention
The reversible water trap that the purpose of this utility model is to propose a kind of effectively draining and can regulates underground water stressor layer as required.
The purpose of this utility model is achieved in that controlled inverse-stopping type water trap is made up of ladle body and filter material two parts, ladle body is T shape, the uncovered bucket of two cavity cylinders by upper and lower different-diameter differing heights is connected to form, the bucket bucket end, be provided with the water seal circle on the ring, last bucket upper port is connected with top cover, the top cover center drilling connects flexible pipe is housed; Following bucket bucket wall time perforate eye, installing cylinder type filter net in the bucket, the nearly barrel end and a bucket upper port have been horizontally disposed with the upper and lower guide strip of cross, its each end links to each other with the tube inwall, right-angled intersection place perforate, vertical active two holes of passing of guide peg, the bar upper end is connected with horizontal water shutoff cover plate.Be embedded with filter material under canal end liner course, following bucket embeds in the filter material, and last bucket is positioned at canal end liner course top.Encircle following barrel of one week of outer wall upper port, be equipped with horizontal sealing layer.
Since implement technique scheme, but the lifting automatic open and close of ponding layer water level hydraulic pressure under this water trap base area, draining automatically, structure is simple relatively, and is practical.
Description of drawings: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is controlled inverse-stopping type water trap structural representation;
Fig. 2 is controlled inverse-stopping type water trap installing view;
Fig. 3 is the cap structure schematic diagram.
Legend: 1, flexible pipe, 2, top cover, 3, cover plate, 4, bolt, 5, the water seal circle, 6, the sealing layer, 7, go up guide strip, 8, eyelet, 9, ladle body, 10, guide peg, 11, lower guide plate, 12, filter material, 13, the lining cutting layer, 14, undisturbed soil, 15, the flexible pipe hole.
The specific embodiment: the utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: shown in Fig. 1-3, controlled inverse-stopping type water trap is made up of ladle body 9 and filter material 12 two parts, ladle body 9 is T shape, the uncovered bucket of two cavity cylinders by upper and lower different-diameter differing heights is connected to form, the bucket bucket end, be provided with robber cement seal 5 on the ring, last bucket upper port is connected with top cover 2, and top cover 2 centers have flexible pipe hole 15, connect in the hole flexible pipe 1 is housed; Following bucket bucket wall time perforate eye 8, installing cylindrical metal filter screen in the bucket, the nearly barrel end and a bucket upper port have been horizontally disposed with the upper and lower guide strip 7 of cross, 11, its each end links to each other with the tube inwall, right-angled intersection place perforate, vertical guide peg 10 active two holes of passing, the bar upper end is connected with horizontal cover plate 3.Be embedded with filter material 12 13 times at canal end liner course, it is made up of medium and small gravel, and following bucket embeds in the filter material 12, and last bucket is positioned at canal end liner course 13 tops.Encircle following barrel of one week of outer wall upper port, be equipped with horizontal sealing layer 6, it is fluid-tight polyethylene film, and this film connects by bolt 4 and is contained on the outer wall of barrel going to the bottom.
Underground water from undisturbed soil 14 soil layers filters through filter material 12, eyelet on following barrel of bucket wall enters in the bucket, again through strainer filtering, treat the rising of inner bucket water position, when hydraulic pressure reached certain numerical value, namely pushing tow cover plate 3 rose, and separates with water seal 5, underground water gushes on 5 of cover plates 3, water seal, and the flexible pipe 1 from the top cover 2 drains at the bottom of the canal; When groundwater table, the hydraulic pressure decline of undisturbed soil 14 soil layers, inner bucket water position, hydraulic pressure descend thereupon, and cover plate 3 falls naturally, is pressed in the water seal 5, and cover plate 3 tops are anhydrous, and water trap stops draining.Flexible pipe 1 can be difficult for by the husky obstruction of canal bed mud with current shifting in water when draining at the bottom of canal.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
