The drainage pipe of the drainage system in the prior art is usually arranged as a steel pipe or a ceramic pipe, so that the weight is large, and the installation and the laying are inconvenient. Therefore, in order to solve the problem of heavy weight of the drainage pipe in the prior art and achieve the effect of reducing the weight of the drainage pipe, the embodiment of the utility model provides a drainage system.

The drainage system provided in the embodiment of the present utility model is described below with reference to fig. 1 to 4.

Specifically, the drainage system is used for draining the tailings dam 4. The tailings dam 4 is a dam built for forming a reservoir for piling various ore tailings, i.e. one side of the tailings dam 4 is a tailings reservoir for piling tailings. For example, taking the tailings dam 4 shown in fig. 1 as an example, the right side of the tailings dam 4 is a tailings pond for piling tailings.

The drainage system comprises a drainage pipe 1 for embedding in a tailing dam 4. The seepage-proofing pipe 1 is arranged as a foam metal pipe body so as to form a porous structure on the pipe wall of the seepage-proofing pipe 1. The porous structure is communicated with the inner side and the outer side of the seepage drainage pipe 1 so that liquid in the dam body can flow through the pipe wall of the seepage drainage pipe 1 and enter the seepage drainage pipe 1. It should be noted that, the foam metal is a special metal material containing foam air holes, which belongs to the material in the prior art, the application only sets the seepage drainage pipe 1 as a foam metal pipe body, and the foam metal is not repeated because the weight of the seepage drainage pipe 1 is reduced on the premise of ensuring that water can enter the seepage drainage pipe 1 from the outside by utilizing the porous structure of the foam metal, so that the foam metal is not improved.

According to the drainage system provided by the embodiment of the utility model, the drainage pipe 1 is formed by the foam metal pipe body and is buried in the tailing dam 4, the pipe wall of the drainage pipe 1 is provided with a porous structure, and the porous structure is communicated with the inner side and the outer side of the drainage pipe 1. In the use process, the moisture in the dam body of the tailing dam 4 enters the seepage drainage pipe 1 through the porous structure on the pipe wall of the seepage drainage pipe 1 and is discharged through the seepage drainage pipe 1.

By the arrangement, the seepage drainage pipe 1 is arranged to be the foam metal pipe body, so that the pipe wall of the seepage drainage pipe 1 is of a porous structure, and compared with the seepage drainage pipe 1 with the same specification in the prior art, the seepage drainage pipe 1 in the embodiment of the utility model has smaller density and lighter weight, thereby achieving the effect of reducing the weight of the seepage drainage pipe 1 and further reducing the laying difficulty of the seepage drainage pipe 1.

In some embodiments of the utility model, the drain tube 1 is provided as a foam aluminium tube. The foamed aluminum is a porous structure formed by adding an additive into aluminum or aluminum alloy and foaming the porous structure, and the foamed aluminum belongs to the material in the prior art. The foam aluminum material has better compressive strength and bending strength, so that the seepage drainage pipe 1 made of the foam aluminum material can bear the pressure in the dam body. In addition, even in a moist environment, the foamed aluminum material is not easy to rust, so that the service life of the seepage drainage pipe 1 can be prolonged.

In some embodiments provided by the present utility model, the number of the drainage pipes 1 includes a plurality of prefabricated pipes 101 connected in sequence, and each prefabricated pipe 101 is configured as a foam metal pipe body. Because the drainage system generally needs a longer length of the drainage pipe 1, if the drainage pipe 1 is configured as an integral structure, the drainage pipe 1 as a whole is inconvenient to transport, and in the embodiment of the utility model, the drainage pipe 1 includes a plurality of prefabricated pipes 101 connected in sequence, and the length of the prefabricated pipes 101 is smaller than that of the drainage pipe 1, so that the difficulty of transporting the drainage pipe 1 in units of the prefabricated pipes 101 is smaller than that of transporting the drainage pipe 1 as a whole. In addition, since the length of the preformed tube 101 is relatively short, production in preformed tube 101 units is less difficult than overall production of the drainage tube 1.

Referring to fig. 2-3, in some embodiments of the present utility model, the drainage tube 1 further comprises a first connector 102 and a second connector 103 for connecting with the first connector 102. One of any adjacent two preformed tubes 101 is provided with a first connector 102 and the other is provided with a second connector 103.

For example, as shown in fig. 2, the first connecting member 102 is provided with an internal thread, and the second connecting member 103 is provided with an external thread, although the reverse is also possible. So set up, the connection structure between first connecting piece 102 and the second connecting piece 103 is simple, the dismouting of being convenient for.

Specifically, the first connection member 102 and the second connection member 103 may each be provided in a sleeve structure. As shown in fig. 2, the sleeve structures are fitted at the mouths of the respective prefabricated tubes 101, for example, the sleeve structures may be fitted inside or outside the mouths. Wherein the overlap of the sleeve structure with the preformed tube 101 should be as small as possible (i.e. the depth of insertion of the sleeve structure into the preformed tube or the depth of insertion of the preformed tube into the sleeve structure should be as small as possible) to reduce the impeding effect of the sleeve structure on the water flow. Alternatively, the preformed tube 101 may be formed directly on the outside or inside of the sleeve structure, such that the preformed tube 101 forms a coupling structure with the sleeve structure after being formed.

Of course, the first and second connection members 102 and 103 are not limited to threaded connections. For example, in other embodiments provided by the present utility model, the first connector 102 and the second connector 103 are connected by fasteners. Specifically, each of the first and second connection members 102 and 103 may include a flange, the flange of the first connection member 102 and the flange of the second connection member 103 are butted, and a fastener is passed through the flange of the first connection member 102 and the flange of the second connection member 103, thereby connecting the first connection member 102 and the second connection member 103.

Alternatively, the fastener may be provided as a threaded fastener, such as a bolt or screw. In this way, the first connector 102 and the second connector 103 are easily detached.

Alternatively, the flange may be sleeved on the outer side of the preformed tube 101 or attached to the end surface of the preformed tube 101. Further, in order to improve the connection strength between the flange and the prefabricated pipe 101, the first connecting piece 102 and the second connecting piece 103 each include a connecting sleeve connected with the flange, and the connecting sleeve may be welded with the flange or be integrally formed. The connecting sleeve is sleeved on the inner side or the outer side of the pipe orifice of the prefabricated pipe 101, namely, the prefabricated pipe 101 is formed on the outer side or the inner side of the connecting sleeve, and the prefabricated pipe 101 and the connecting sleeve form a connecting structure after being formed. The connection area of the connection sleeve and the prefabricated pipe 101 is large, so that the connection strength is large, and the connection strength between the flange plate and the prefabricated pipe 101 can be increased.

Of course, the first connector 102 and the connector are not limited to being connected by fasteners, and for example, in some embodiments provided by the present utility model, the first connector 102 and the second connector 103 may be adhesively connected or welded connected.

The water guide pipe 3 and the seepage drainage pipe 1 are connected with the water collecting pipe 2, and the water guide pipe 3 and the seepage drainage pipe 1 are arranged on one side, far away from the tailing pond, of the water collecting pipe 2. The height of the water guide pipe 3 near one end of the water collecting pipe 2 is higher than that of the water guide pipe 3 far from one end of the water collecting pipe 2. The height of the position of the seepage drainage pipe 1 close to the end of the water collection pipe 2 is lower than the height of the position of the seepage drainage pipe 1 away from the end of the water collection pipe 2.

In the actual operation process, water in the tailing dam 4 flows into the water collecting pipe 2 through the seepage drainage pipe 1, and water in the water collecting pipe 2 is drained through the water guide pipe 3.
