Detailed Embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0030] Embodiment 1: The purpose of this embodiment is to propose a transformed seepage water collection well for the drainage culvert of the tailings pond.

[0031] As From Figure 1 to Figure 2 shown, it includes the base soil layer 1.

[0032] On the base soil layer 1, a vertically extending collection well 2 is provided. At the wellhead of the collection well 2, an inclined intercepting grille 5 is detachably connected. The left and right ends of the intercepting grille 5 are installed at the wellhead of the collection well 2 through installation bolts, and the left end of the intercepting grille 5 is lower than the right end. On the left side of the collection well 2, a sedimentation tank 6 with an upper opening structure is provided. The top of the sedimentation tank 6 is flush with the left end of the intercepting grille 5. A filter screen is detachably connected inside the sedimentation tank 6. Hooks are provided inside the sedimentation tank 6, and the filter screen is hung on the hooks. At the bottom of the collection well 2, a sump well base 202 is provided, and a waterproof layer 203 is provided on the sump well base 202. In this embodiment, the waterproof layer 203 can be selected as polyurethane waterproof coating.

[0033] A drain pipe 10 is provided inside the collection well 2. The drain pipe 10 extends in the left-right direction and passes through the drainage culvert to be connected to the external drainage system. The drain pipe 10 is located in the upper part of the collection well 2. When the seepage water level in the collection well 2 is higher than the position where the drain pipe 10 is located, the seepage water flows into the drain pipe 10, thereby preventing the seepage water from overflowing the collection well 2 when it is collected intensively.

[0034] Seepage holes 201 are provided on the inner side wall of the collection well 2. The seepage water flowing into the collection well 2 penetrates into the collection well 2 through the seepage holes 201.

[0035] The outside of the collection well 2 is wrapped with a filter layer. The filter layer includes a first gravel layer 3 and a second gravel layer 4. The first gravel layer 3 is wrapped on the outer side surface of the collection well 2, and the second gravel layer 4 is wrapped on the outer side of the first gravel layer 3. The gravel particle size in the first gravel layer 3 is larger than the gravel particle size in the second gravel layer 4. The seepage water seeping out from the seepage holes 201 flows into the first gravel layer 3 and then into the second gravel layer 4. After being filtered by the two gravel layers, the seepage water is preliminarily filtered and finally infiltrates into the base soil layer 1.

[0036] A backfill soil layer 9 is laid on the right side of the collection well 2. The backfill soil layer 9 is laid on the upper sides of the filter layer and the base soil layer 1, and the backfill soil layer 9 is flush with the right end of the collection well 2, so that the right part of the culvert is higher than the left part and the right part is flush with the right side of the collection well 2.

[0037] A rope receiver 8 is provided at the wellhead of the collection well 2. A lifting rope is fixedly connected to the rope receiver 8. The lifting rope passes through the intercepting grille 5 and hangs down into the collection well 2. The lower end of the lifting rope is fixedly connected with a silt scraper 7. The silt scraper 7 includes a silt collection frame 701. The silt collection frame 701 fills the radial gap of the collection well 2, and an upper-opening silt collection groove is formed inside the silt collection frame 701. A lifting rope connecting frame 704 is fixedly connected inside the silt collection frame 701, and the lower end of the lifting rope is fixedly connected with the lifting rope connecting frame 704.

[0038] The upper surface of the sludge collection frame 701 is fixedly connected with a scraper 703. The scraper 703 is of an annular structure, and the outer side surface of the scraper 703 abuts against the inner wall of the collection well 2, and an inclined surface is provided at the top of the scraper 703.

[0039] A bottom plate 702 is provided at the bottom of the sludge collection frame 701, and a plurality of water through holes penetrating up and down are provided on the bottom plate 702.

[0040] Working principle: The seepage water flows into the culvert, flows inward along the culvert, and finally flows through the backfill soil layer 9, flows into the collection well 2 through the intercepting grille 5, and the seepage water flows into the collection well 2 for collection.

[0041] The sundries in the seepage water are blocked by the intercepting grille 5, and the blocked sundries accumulate on the intercepting grille 5. Since the intercepting grille 5 is inclined, and at the same time the seepage water continuously flushes on the intercepting grille 5, the sundries slowly fall into the sedimentation tank 6, and thus fall into the filter screen of the sedimentation tank 6, thereby preventing the sundries from accumulating on the intercepting grille 5.

[0042] When the collection well 2 is used for a long time, sludge will be generated on the well wall. In order to prevent the sludge from corroding the well wall and also to prevent the sludge from blocking the seepage holes 201, the handle on the rope winder 8 is rotated to drive the rope of the lifting rope to wind, and the winding of the lifting rope drives the sludge scraper 7 to move upward. When the sludge scraper 7 moves upward, the scraper 703 peels the sludge from the well wall, and the sludge falls into the sludge collection frame 701. Then the staff removes the intercepting grille 5, and then pulls out the sludge collection frame 701 from the collection well 2 to collect the sludge.

[0043] Thus, the sundries can be washed into the sedimentation tank 6 through the inclined intercepting grille 5, so as to collect the sundries uniformly, and also prevent the sundries from accumulating on the intercepting grille 5 and affecting the seepage water from entering the collection well 2. At the same time, the sludge on the well wall can be peeled off and collected by pulling the sludge scraper 7, making the sludge cleaning more convenient.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
