Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of construction facilities for pool-filled dams, and specifically relates to an overflow water diversion device for pool-filled dams. Background Technology
[0002] The centerline method for dam construction, with the secondary dike constructed using the pool-filling method, is a conventional dam construction method in mines. However, with the optimization of mineral processing technology, the particle size of tailings entering the reservoir has become finer. When constructing the secondary dike using the pool-filling method, the water in the slurry cannot completely infiltrate (the uninfiltrated water is called pool overflow). This water needs to be naturally diverted to the dam's front tailings barrier. Currently, the diversion operation involves siphoning the overflow generated from pool filling to the next level secondary dike via a siphon pipe, then flowing through a simple drainage ditch on the secondary dike to drainage ditches on both banks, and finally flowing into the tailings barrier. This method allows the overflow to flow directly on the secondary dike, carrying a large amount of tailings during its flow, resulting in an increased sand content in the overflow entering the tailings barrier and increasing dredging costs. Therefore, it is essential to develop a pool-filling dam overflow diversion device that can solve the above problems. Utility Model Content
[0003] The purpose of this utility model is to provide a device for diverting overflow water from a dam in a pool filling project.
[0004] The purpose of this utility model is achieved as follows: it includes a drainage channel, a base, a slide rail, a support platform, a support rod, and a handle. The drainage channel is a semi-circular channel. Slide rails are fixedly provided on both sides of the outer surface of the drainage channel along the circumference. The base is provided with a sliding groove and is located at the bottom of the drainage channel. The sliding groove of the base slides in cooperation with the slide rail. One slide rail corresponds to one base. Support platforms are symmetrically fixed on the upper part of the outer surface of the drainage channel. There are at least two support platforms. The support platforms are provided with slots. The support rod is inserted obliquely into the slots. A handle is fixedly provided on the side of the support platform.
[0005] It should be noted that it is common knowledge in the field that the slide rail and the slide groove are matched. Since the slide rail is arc-shaped, the slide rail is also arc-shaped.
[0006] The drainage channel can be made of PE.
[0007] Preferably, the overflow diversion device of the pool filling dam has multiple diversion channels connected end to end, and an anti-seepage layer can be pasted at the connection point; during use, the appropriate length of the diversion channel and the appropriate number of diversion devices are selected according to the required diversion distance on site.
[0008] Preferably, the inner diameter of the drainage channel is 200mm~400mm.
[0009] Preferably, the base is a counterweight base, specifically a stainless steel base, to increase weight and improve stability.
[0010] Preferably, the slide rail is an anti-slip slide rail and the slide groove is an anti-slip slide groove. Both the anti-slip slide rail and the anti-slip slide groove are anti-slip structures well known to those skilled in the art. For example, the slide rail can be designed as a common I-shaped slide rail, and the slide groove can also be designed as an I-shaped slide rail, so that the slide rail can slide stably in the slide groove. In this way, when the drainage groove is lifted, the base is also suspended and taken away together. Alternatively, common limiting members can be set at both ends of the slide rail. When the end of the slide rail slides into the slide groove, it is blocked by the limiting members to prevent the slide rail from falling out of the slide groove.
[0011] The beneficial effects of this utility model are as follows: This utility model diverts overflow water from the ore-filled pool through a diversion channel, which can reduce the accumulation of tailings in the slag-blocking dam; This utility model is easy to install and disassemble, and can be advanced and deployed towards the top of the dam as the ore is filled in the pool, making it flexible in its deployment; This utility model effectively reinforces the diversion channel through a support structure composed of support rods and support platforms, resisting the impact of flowing water and ensuring the stability of the diversion channel; This utility model, through the sliding structure of the base and the diversion channel, can slide the diversion channel up to one side facing down, making it easy to pour out residual water and tailings, which is easier to operate than lifting and inverting the diversion channel.

[0016] The present invention will be further described below with reference to the embodiments and accompanying drawings, but this does not limit the present invention in any way. Any changes or substitutions made based on the teachings of the present invention shall fall within the protection scope of the present invention.
[0017] Example 1
[0018] As attached Figures 1-3As shown, the overflow diversion device for the dam filling in this embodiment includes a diversion channel 1, a base 2, a slide rail 3, a support platform 4, a support rod 5, and a handle 6. The diversion channel 1 is a semi-circular channel with an inner diameter of 300mm and is made of PE. Slide rails 3 are fixedly installed on both sides of the outer surface of the diversion channel 1 along the circumference. The base 2 is provided with a sliding groove and is located at the bottom of the diversion channel 1. The sliding groove of the base 2 is slidably engaged with the slide rail 3. One slide rail 3 corresponds to one base 2. Support platforms 4 are symmetrically fixed on the upper part of the outer surface of the diversion channel 1. There are at least two support platforms 4. The support platform 4 is provided with a slot. The support rod 5 is inserted obliquely into the slot. A handle 6 is fixedly installed on the side of the support platform 4.
[0019] The working principle and process of this utility model are as follows: During the dam construction process, an overflow diversion device is horizontally arranged along the sub-dike below the ore filling in the dam. The base 2 serves to support the diversion channel 1. A support rod 5 is installed, which is obliquely supported on the diversion channel 1 to reinforce it. The overflow water generated during the ore filling process flows into the diversion channel 1 and is diverted to the drainage facilities on both banks (such as flowing into the sedimentation tank through a drainage pipe), preventing the overflow water from flowing on the sub-dike. After being diverted by this device, the accumulation of tailings in the dam is effectively reduced, thus reducing the cost of tailings removal from the dam.
[0020] As the ore filling in the pool continues to advance towards the top of the dam, the overflow diversion device of the dam in this layer is removed and installed and diverted in the next layer above. During removal, first remove the support rod 5, then remove the connecting part of the adjacent diversion channel 1, and then hold the handle 6 to lift one side of the diversion channel 1 upwards. The slide rail 3 of the diversion channel 1 slides along the base 2. The residual water and tailings in the diversion channel 1 are then poured out.
