A kind of combined water-drainage well and Tailings Dam
The utility model belongs to mining industry technical field, and in particular to a kind of combined water-drainage well, more particularly to it is a kind of applicable
In the combined water-drainage well of flat type Tailings Dam.
In the area such as Plain, Gobi desert because available without enough mountain valleys, usually on level land, surrounding builds a dam and builds Tailings Dam heap
Tailing is deposited, the form of one gully connection drainpipe of flat type Tailings Dam generally use is drained off floodwaters.
Flat type Tailings Dam is smaller compared with mountain valley-type Tailings Dam catchment area, and especially its reservoir capacity for flood control of initial operating stage is larger,
Substantially without requirement of drainning off floodwaters, drainage system, which meets, at this time arranges tailing clearing rinsing requirement.
After tailing accumulation absolute altitude is more than initial dam top mark height, the reservoir capacity for flood control of Tailings Dam is obviously reduced, and needs large-size
Drainage system could meet requirement of drainning off floodwaters.
The flood discharge capacity of usual frame-type gully is larger, but relative to the globality of window type gully its structure compared with
Difference, strcture safety is relatively low, and the load that derrick bottom is born is maximum.
If Tailings Dam initial stage tailing water is stored in library not outer row, tailings cannot be preferably classified before dam, and bottom storehouse tailings is difficult
With consolidation, cause the mechanics index of physics of the region tailings relatively low, it is very unfavorable to the stabilization in tailing dam later stage.
How effectively to solve in the case that flat type Tailings Dam only arranges a gully, both to have can guarantee initial stage clarification
Water discharges in time, accelerates the consolidation of tailings, and can meet the requirement of later stage Tailings Dam flood control safety, while improving draining well construction
Safety and dam body stabilization safety, be still the insoluble problem of industry.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, the utility model is intended to provide a kind of structural strength
Combined water-drainage well high, safety is good, to meet draining, the flood control demand in Tailings Dam each period.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of combined water-drainage well, including it is hollow
Well seat, be equipped with the window type draining section of connection successively from the bottom to top at the top of well seat and frame-type drain section, the window type
Draining section is connected to well seat inner cavity.
In the utility model, window type draining section can be used and the existing same or similar structure of window type gully；Frame
Posture draining section can be used and the same or similar structure of available frame formula gully.
Further, the window type draining section and frame-type drain section integrally connected.
Further, the window type draining section and well seat integrally connected.
Further, further include the drainpipe being connected to well seat inner cavity.
Based on same inventive concept, the utility model also provides a kind of Tailings Dam, is equipped in the Tailings Dam as described above
Combined water-drainage well.
The utility model is particularly suitable for the excretion of tailing clearing rinsing and flood in flat type Tailings Dam.
The combined water-drainage well of the utility model is the frame-combined draining well construction of window-, is particularly suitable for flat type
Tailings Dam is only capable of the case where one gully of arrangement.Gully can be divided into two parts according to initial dam top mark height, bottom is window
Mouth formula drains section, largely enhances the globality of draining well construction, improves the degree of safety of draining well construction；On gully
Portion drains section using frame-type, considerably increases its flood discharge capacity, it is ensured that the flood control safety of Tailings Dam；Can according to return water, drain off floodwaters
The size of design gully hatch section and frame section is calculated separately with requirements such as structures.
At flat type Tailings Dam initial stage, tailing water can be discharged by the window of gully outside library in time, be accelerated with reaching
The purpose of the intensity and increase safety of dam body stability of bottom storehouse fine grain tailings before consolidation bottom storehouse tailings, raising dam, to later stage heap
It is high highly beneficial；As tailing rises, gradually uses armored concrete closure to fill in row and block window type draining section, improve draining
The safety of structure that well blocks reduces the risk that gully collapses caused by blocking the reasons such as failure；Tailing accumulates absolute altitude
After initial stage dam crest, tailing clearing rinsing and flood can pass through outside frame-type draining section discharge library, ensure the flood control of Tailings Dam
The combined water-drainage well of the utility model can ensure that Tailings Dam initial operating stage tailing clearing rinsing is discharged outside library in time,
Meet the return water requirement for selecting factory, while window type draining section is filled in row using closure and blocked convenient for construction, is conducive to raising and blocks
Safety of structure, reduce because blocking the risk that gully collapses caused by reasons such as failure.
The use of the combined water-drainage well of the utility model can accelerate the classification of bottom storehouse region tailing and consolidation before initial dam,
The mechanics index of physics of the region tailings is improved, and then improves the stability against sliding of dam body, it is high to be conducive to later stage heap.

There are the window type draining section 1 and frame-type draining section 2 of connection, the window type draining section 1 to be connected to 3 inner cavity of well seat.
Wherein, the window type draining section 1 and frame-type drain 2 integrally connected of section；The window type draining section and well seat
Integrally connected, to improve the globality of combined water-drainage well.
It further include the drainpipe 4 being connected to 3 inner cavity of well seat.
When building the combined water-drainage well of the utility model, first, position, window type draining section and the frame of gully are determined
