Embodiment 1

[0039] Example 1 as Figure 4 to Figure 12As shown, the window type drainage well in embodiment 1 is used as a seepage collection well, including a well shaft and a well seat, the well shaft is located on the top of the well seat, the well shaft is provided with a well wall 1, and the well wall 1 is provided with a drainage window 18, and the drainage window 18 The inner wall is in the shape of a truncated cone, and the inner diameter of the truncated circular inner wall is small and the outer diameter is large. Drainage window 18 is provided with different-diameter pipe 2, and the outer wall of different-diameter pipe 2 is compatible with the inner wall of drainage window 18; The inner wall of the reducing pipe 2 is matched, the filter device is filled in the cage 3, and the outside of the reducing pipe 2 (the right end of the present embodiment) is provided with a first flange 8. The outer side of the cage 3 (the right end of the cage 3 in this embodiment) is provided with ...

Embodiment 2

[0045] Example 2 as Figure 13 As shown, the first flange 8 of a window-type drainage well in Embodiment 2 is fixed with a blind flange 21 by bolts. The blind flange 21 is a flat flange without water holes, and the blind flange is used to block the drainage window. Other structures of embodiment 2 are the same as embodiment 1.

[0046] The construction and use steps of the window type drainage well in Embodiment 2 of the present invention are as follows:

[0047] (1) Excavation of the well base: Excavate to the design depth, the buried depth of the well base is generally not less than 2 / 3 of the height of the well base, and the bearing capacity of the foundation is generally not less than 200kPa.

[0048] (2) Manufacture of well base: supporting formwork, placing steel bars, pouring concrete, and curing.

[0049] (3) Manufacture of the wellbore: support the formwork, place steel bars, pour concrete, and maintain. A different-diameter pipe is placed at the position of the or...

Abstract

The invention discloses a window-type drainage well and a construction method of the window-type drainage well. The window-type drainage well comprises a well casing and a well base. The well casing is provided with a well wall. The well wall is provided with a drainage window. The inner wall of the drainage window is of a circular truncated cone shape. The drainage window is provided with a reducing pipe. The outer wall of the reducing pipe is matched with the inner wall of the drainage window. A cage is arranged in an inner cavity of the reducing pipe and matched with the inner wall of the reducing pipe, the cage is filled with a filtering device, and a first ring flange is arranged on the outer side of the reducing pipe. The first ring flange is connected with a second ring flange, and the second ring flange is connected with a seepage collection device. Or a blind ring flange is fixed on the first ring flange. The construction method of the window-type drainage well comprises the steps of excavating to form a well base foundation, manufacturing the well base, manufacturing the well casing, placing the cage, the filtering plate, coarse sand bags and gravel bags in the reducing pipe, wherein the coarse sand bags and the gravel bags are wrapped in geotechnical cloth, and connecting the first ring flange with the second ring flange or the blind ring flange. According to the window-type drainage well and the construction method of the window-type drainage well, a window can be blocked off, and the window-type drainage well can be further transformed into a seepage collection well; the window-type drainage well is flexible in use and capable of integrating two functions, thereby reducing investments.

Description

technical field [0001] The invention relates to a drainage well, in particular to a window-type drainage well for tailings pond backwater or tailings pond with small catchment area to discharge flood. Background technique [0002] Drainage well is one of the important structures of mine tailings facilities. Most of the rain and snow water and tailings clarified water falling in the catchment area of ​​tailings pond pass through it, and then are discharged out of the pond through structures such as drainage culverts or tunnels to ensure that the tailings The mine dam will not be flooded and the tailings clarified water will be returned to the concentrator for reuse. When the discharge capacity of the drainage structure required by the tailings pond is small, the window type drainage well is generally used. The window-type drainage well is built at one time, and there are drainage windows at different elevations on the well wall. The well has the advantages of good structural...
