Abstract
The utility model discloses a drainage piezometer tube under an anti-osmosis membrane of a dike or a dam. The drainage piezometer tube comprises a water collection tube, wherein one end of the water collection tube is opened, while the other end of the water collection tube is sealed; the wall of the water collection tube is provided with water permeation holes and the outer surface of the water collection tube is wrapped with a layer of water permeation geotextile; the opened end of the water collection tube is connected with a connecting tube; the connecting tube is connected with an effluent piezometer tube; the effluent piezometer tube is internally provided with a water pump; the water pump is connected with an effluent tube; and the effluent tube extends out of the effluent piezometer tube. Compared with the prior art, the drainage piezometer tube has the advantages of firstly being reasonable in design, simple in structure, low in cost, convenient to install, wide in application range and beneficial to popularization and utilization, and secondly effectively preventing the anti-osmosis composite membrane from being torn by back pressure after use due to the advantage of popularization and application, protecting the dam, and avoiding security incidents.
Description
Technical field
The utility model relates to the dam impervious and monitoring technology field, in particular relates to a method for preventing the reservoir water level is lowered by anti-Si film backpressure muster and tear of the device.
Background technology
In recent years, hydraulic engineering has obtained greatly developing in China, and the safety of hydraulic engineering receives increasingly extensive concern, and wherein the safety of dam is paid attention to especially.Impermeable have important status in hydraulic engineering, so also obtained in recent years using widely as the composite geo-membrane of barrier material.According to " the Hydraulic and Hydro-Power Engineering Technical code for application of geosynthetics " of Chinese Water Conservancy cloth promulgated by the ministries or commissions of the Central Government, the impermeable compound back-pressure that receives is heaved when preventing that reservoir level from reducing, and this standard has pointed out to be provided with under the film necessity of draining depressurized system.For new construction, in dam body, can pre-buried gutter be discharged by water; But for the stabilization works of getting rid of the danger of building dam; Owing to can't pass former dam body and bury underground; Gutter is often laid to dam abutment along the axis of dam direction during design by group at the bottom of the dam, and can only dig a water discharge tunnel at dam abutment respectively along massif portion, the water in the gutter is entered in the tunnel drain.Because the digging tunnel construction duration is long, the construction difficulty is big, cost is high; Thereby limited applying of impermeable composite membrane dam facing technology, some work even is not provided with the draining depressurized system, and the result causes impermeable composite membrane to be torn; Bring potential safety hazard to dam, even cause security incident.
The utility model content
The technical problem that the utility model will solve provide a kind of reasonable in design, simple in structure, cost is low is used for the draining piezometer tube under the dyke dam permeable membrane.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of draining piezometer tube that is used under the dyke dam permeable membrane is characterized in that: comprise a header, an end opening of header, other end sealing; Offer permeable hole on the tube wall of header, the header coated outside has the permeable geotextiles of one deck; The openend of header links to each other with a tube connector, and tube connector links to each other with a water outlet piezometer tube; Be provided with a water pump in the water outlet piezometer tube, water pump connects an outlet pipe, and outlet pipe extend out to water outlet piezometer tube outside.
Further, said tube connector is a hose connector, and tube connector is fixed on the header through a terminal pad.
Further, said water pump is a micro pump, and it is fixedly mounted in the water outlet piezometer tube, and perhaps activity is placed in the water outlet piezometer tube, takes which kind of mode to determine according to on-the-spot actual needs.
The utility model compared with prior art has the following advantages: the first, reasonable in design, simple in structure, cost is low, easy for installation, applied widely, help applying; The second, owing to possess the advantage of applying, can prevent effectively that after use impermeable composite membrane receives back-pressure and tears, can play a protective role to dam, avoid taking place security incident.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1 is header, and 2 is permeable geotextiles, and 3 is tube connector, and 4 are the water outlet piezometer tube, and 5 is water pump, and 6 is outlet pipe, and 7 is permeable hole, and 8 is terminal pad.
The specific embodiment
In the present embodiment, with reference to Fig. 1, the said draining piezometer tube that is used under the dyke dam permeable membrane comprises the header 1 that an employing steel pipe is processed, an end opening of header 1, other end sealing; Offer permeable hole 7 on the tube wall of header 1, header 1 coated outside has the permeable geotextiles 2 of one deck, and percolating water can be got in the header 1 through the permeable hole 7 of tube wall; The openend of header 1 links to each other with a tube connector 3, and tube connector 3 links to each other with a water outlet piezometer tube 4; Be provided with a water pump 5 in the water outlet piezometer tube 4, water pump 5 connects an outlet pipe 6, and outlet pipe 6 extend out to water outlet piezometer tube 4 outsides, so that draining.
Tube connector 3 is a hose connector, and tube connector 3 is fixed on the header 1 through a terminal pad 8.
Water pump 1 is a micro pump, and it is fixedly mounted in the water outlet piezometer tube 4, and perhaps activity is placed in the water outlet piezometer tube 4, takes which kind of mode to determine according to on-the-spot actual needs.
During use, can directly install at the scene, header 1 is passed the steel concrete teeth groove of dam abutment after; Link to each other with water outlet piezometer tube 4 through tube connector 3; Lay to dam crest height together along near massif dam facing or the dam abutment then, should lay by certain gradient during laying, be convenient to water level in the measuring tube; The caliber of water outlet piezometer tube 4 is not less than 15 centimetres, can record table hydrostatic level in the pipe with universal meter, and the average height of phreatic line under hence one can see that the impermeable composite membrane has also just been known the impermeable effect of impermeable composite membrane.When reservoir level reduces, be higher than reservoir level like water level in the pipe of measuring, then point out impermeable composite membrane to receive back-pressure, need to open water pump 5 this moment and draw water, with the reduction back-pressure, prevent that impermeable composite membrane from heaving.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
