Description

Technical Field

[0001] The utility model belongs to the technical field of tailings dry-type piling, and in particular relates to a frame-type drainage well. Background Art

[0002] Artificial sand and gravel are sands processed by sand making machines and other auxiliary equipment. The finished products are more regular and can be processed into sands of different rules and sizes according to different process requirements. As an environmentally friendly and energy-saving building material product, artificial sand and gravel are gradually favored by the market. Therefore, the market size of the artificial sand and gravel industry has continued to grow in recent years. With the development of the artificial sand industry, a large number of dry storage yards for sand washing tailings have also appeared in various places. Because the tailings particles are extremely fine, the water content of the tailings after dehydration in industrial production is still relatively high. Strengthening drainage and consolidating the tailings as soon as possible is crucial to the stability of the tailings yard.

[0003] At present, the flood discharge facilities installed in the tailings dry storage yard are mainly drainage wells. The frame-type drainage well is the most common type in actual engineering applications due to its strong discharge capacity. During the operation of the tailings dry storage yard, as the tailings accumulation surface rises, when the previous drainage well is about to be buried, the next drainage well will be activated, and then the previous drainage well will be blocked, and the drainage well will completely lose its function. Based on the above, the cost of the drainage well is high and direct blocking is a huge waste. Utility Model Content

[0004] The utility model aims to provide a frame type drainage well to overcome the above technical defects.

[0005] In order to solve the above technical problems, the utility model provides a frame-type drainage well suitable for tailings dry storage yard, comprising:

[0006] A base, suitable for connecting a culvert or a tunnel;

[0007] A derrick is fixed on the base, and a drainage structure is arranged at the frame of the derrick, so that when tailing mud is piled up to the wellhead, crushed stones are used to fill the derrick to transform the frame-type drainage well into a three-dimensional radial drainage well.

There are multiple columns, and the multiple columns are arranged at intervals along the circumference of the ring beam, and the bottom end of the lowest column is fixed to the base;

[0011] The drainage structure is arranged at the intersection of the column and the ring beam.

[0030] The following is an explanation of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0031] It should be noted that, in the present utility model, the top, bottom, left and right in the figure are deemed to be the top, bottom, left and right of the frame-type drainage well described in this specification.

[0032] The exemplary embodiments of the present invention are now introduced with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0033] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0034] This embodiment involves a frame-type drainage well, which is mainly applicable to tailings dry storage yards. Figure 1 The frame-type drainage well includes a base 10 and a well frame 20.

[0035] The base 10 is suitable for connecting to a culvert or a tunnel, and the base 10 serves as a support body of the derrick 20 .

[0036] The derrick 20 is fixed on the base 10 , and a drainage structure is arranged at the frame of the derrick 20 , so that when tailing mud is piled up to the wellhead, the derrick 20 is filled with crushed stones to transform the frame-type drainage well into a three-dimensional radial drainage well.

[0037] Compared with the traditional buried drainage well, the utility model proposes to set a drainage structure in the well frame 20 of the frame drainage well. When the frame drainage well runs to the top of the well, gravel is used to fill the well, and finally the frame drainage well will become a three-dimensional radial drainage well. This well can effectively reduce the infiltration line in the tailing mud accumulation body and improve the stability of the tailing mud accumulation body.

[0038] In other words, the frame-type drainage well has two functions. The first function is to serve as a drainage well, through which the flood within the catchment area of ​​the tailings pond is drained and collected, and finally the flood is discharged out of the pond through the culvert or tunnel below the drainage well, so as to ensure the flood control safety of the tailings pond and avoid the risks of flooding. The second function is to serve as a three-dimensional radial drainage well, that is, filling the frame-type drainage well with gravel to transform it into a three-dimensional radial drainage well, which promotes the discharge of seepage, effectively lowers the infiltration line, and is beneficial to the drainage and consolidation of tailings mud, thereby enhancing the stability of the dam body.

[0039] In some specific embodiments, the derrick 20 includes at least a ring beam 21 and a column 22 .

[0040] There are multiple ring beams 21 , and the multiple ring beams 21 are arranged at intervals along the vertical direction, that is, the multiple ring beams 21 are coaxially arranged, and there is a distance between two adjacent ring beams 21 .

[0041] The column 22 is arranged between two adjacent ring beams 21, and both ends of the column 22 ( Figure 1 The upper and lower ends of the column 22 are respectively connected to two adjacent ring beams 21, and the columns 22 are arranged at intervals along the circumference of the ring beam 21. The bottom end of the bottom column 22 is fixed to the base 10, and finally forms Figure 1 The structure shown.

[0042] Please continue reading Figure 1 , two adjacent columns 22 and two adjacent ring beams 21 define a water inlet 30. That is, the frame grid of the frame-type drainage well is the water inlet 30, and the water in the tailings dry dump flows from the water inlet 30 into the base 10, and then flows from the base 10 into the culvert or tunnel.

[0043] The frame-type drainage well further includes an arched cover plate 40, which is disposed at the water inlet 30 to block the water inlet 30. Figure 2 As shown, the arched cover plate 40 is in a segmented manner and is closely attached to the ring beam 21 and the column 22, so that the water inlet 30 formed by the two adjacent ring beams 21 above and below and the two adjacent columns 22 on the left and right is blocked.

[0044] The drainage structure is arranged at the intersection of the column 22 and the ring beam 21. Figure 2 and Figure 3 The seepage drainage structure includes a pre-buried pipeline 51 and a seepage drainage pipe 52.

[0045] Among them, Figure 1 As shown, the pre-buried pipe 51 is buried at the intersection of the frame of the derrick 20 to connect the inside and outside of the well. Figure 2 and Figure 3 As shown, the drainage pipe 52 is connected to the outer well opening of the pre-buried pipeline 51.

[0046] When constructing a drainage well, pre-buried pipes 51 are arranged along the columns 22. The vertical spacing of the pre-buried pipes 51 is the same as the vertical spacing of two adjacent ring beams 21, and the number of the pre-buried pipes 51 is the same as the number of columns 22. When the dry pile tailings are piled to the corresponding reserved pipe interface elevation, a drainage pipe 52 is connected at each interface.

[0047] Specifically, as the dry pile tailings accumulation surface rises, the arched cover plate 40 is gradually added to block the water inlet 30. When the dry pile tailings accumulation surface rises to the pipe mouth height of the corresponding elevation pre-buried pipeline 51, the pipe mouth is connected to the drainage pipe 52, and the work is repeated as the tailings pile rises until it accumulates to a position close to the well top. When the next drainage well is activated, the inside of the drainage well is filled with crushed stones to make it a three-dimensional radial drainage well, and the seepage is discharged from the drainage pipe 52, effectively reducing the infiltration line.

[0048] In some specific implementations, the ring beam 21 and the columns 22 need to be built during the engineering construction, and the arched cover plate 40 is gradually used to block the water inlet 30 as the tailings pile surface rises during the operation of the tailings dry dump.

[0049] The utility model relates to a frame-type drainage well, which is mainly suitable for tailings dry storage yard. The frame-type drainage well is provided with a drainage structure at the intersection of the frame, and the drainage structure is composed of a pre-buried pipeline and a drainage pipe. When the frame-type drainage well runs to the top of the well, crushed stones are used to fill the well. Finally, the frame-type drainage well will become a three-dimensional radial drainage well, that is, it can still function after being buried by tailings.

[0050] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
