Description
Technical field
The utility model relates to a kind of debris flow drainage guide structure.Be applicable to Hydraulic and Hydro-Power Engineering, mining engineering.
Background technology
Domestic in engineering construction processes such as western water power, mining, owing to limited by the high mountain gorge orographic condition, seek in smooth open slag place difficulty, and therefore utilizing the relative open area heap in the natural cheuch exit or entrance of a clitch to abandon the engineering construction waste is the engineering reality that can't avoid.Because the slag field that waste forms has changed primitive groove degree of lip-rounding attitude, makes former cheuch streamflow condition change.For solving the primitive groove water problems, facility drainings such as necessary engineering measure such as culvert, drainage tunnel, flood discharging groove need be set usually.General; For slag field homeostasis and downstream safety thereof; Construction period and permanent runtime are according to the natural incoming flow situation in gully and combine aspect factors such as slag field layout, surrounding terrain condition and design flood standard to confirm that concrete row leads measure, simultaneously slag field upstream and downstream are carried out water and soil conservation.
The exit or entrance of a clitch at the western mud-rock flow cheuch of China is provided with the slag tip that blocks cheuch fully; In case basin, slag tip upper reaches heavy rain causes mud-rock flow; Mud-rock flow is held solids such as the mud wrapped up in, piece stone, trees under the arm and is descended along the gully; For solving the drainage tunnel of common scale that former river course ditch-water is arranged on the equal elevation of original bed because slow possibly can't the row fully of tunnel base slope led mud-rock flow; Thereby probably cause before the drainage tunnel or closely and stop up in the section of hole; Cause flood, mud, solids etc. all alluvial make follow-up flood level constantly raise and finally bypass the dam site so that burst in the slag field at the upper reaches, slag field, thus the relevant building in downstream, personnel, river course etc. are caused serious threat.In a single day therefore, the slag field is set, except that considering conventional drainage, in the time of also must considering mud-rock flow what plug to take place, studies corresponding mud-rock flow and handle prediction scheme, rational engineering measure is set at the exit or entrance of a clitch of western debris flow gully.
Summary of the invention
The technical problem that the utility model will solve is: according to the problem of above-mentioned existence, provide a kind of safe and reliable, building to arrange debris flow drainage guide structure simple, that construction investment is saved.
The technical scheme that the utility model adopted is: the debris flow drainage guide structure; Position, the exit or entrance of a clitch at natural cheuch is provided with slag tip; The waste heap-shaped becomes slag dam in the slag tip; Form storage capacity in slag dam and the cheuch; It is characterized in that: high and low two elevations and level are set to high-order import of the drainage tunnel that staggers and the import of drainage tunnel low level in the storehouse, the slag dam upper reaches, both are connected an end of shared barrel section respectively with low level drainage tunnel barrel section through high-order drainage tunnel barrel section, and the shared barrel section other end is connected with the drainage tunnel outlet.
The high-order import floor elevation of drainage tunnel is higher than sedimentation elevation and leaves the margin of safety of 1 ~ 2m.
Said high-order drainage tunnel barrel section and low level drainage tunnel barrel section and shared barrel section tie point are positioned at the import of drainage tunnel low level and silt up outside the influence basin.
Said slag tip upstream and downstream is provided with the gradient of 1:1.5 ~ 2.0.
The scarfing cinder passage is laid in the bank slope position in the domatic or storehouse, the said slag dam upper reaches.
The beneficial effect of the utility model is: through combining slag tip, the dragon new line formula drainage tunnel of high and low different elevation imports is set, can effectively handles the mud-rock flow in the cheuch of the slag tip upper reaches; Guarantee that the row who realizes flood and rare property muddy water leads ability, the mud-rock flow solids is then formed " row, retaining, clear " integrated treatment measure, both made full use of slag tip; Simplifying engineering again arranges; Save engineering quantity and investment, guarantee slag tip self and safety of downstream thereof, operation is very simple.
Description of drawings
Fig. 1 is the plan view of the utility model.
Fig. 2 is the sectional side elevation of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2; Present embodiment is a kind of row's guide structure of mud-rock flow; Position, the exit or entrance of a clitch at natural cheuch is provided with slag tip, and the storage capacity that utilizes slag tip and cheuch to form is reserved alluvial storage capacity as the mud-rock flow solids, and artificial waste is piled up the slag dam that forms in the slag tip; In storehouse, the slag dam upper reaches, select suitable position to drain rare property muddy water or flood through the drainage tunnel that high and low two elevation imports are set; Said high and low import is high-order import 2 of drainage tunnel and drainage tunnel low level import 1, and not only elevation is different in these two imports, and the certain distance (as shown in Figure 1) that also staggers in the horizontal direction; Two imports are connected an end of shared barrel section 5 respectively with low level drainage tunnel barrel section 3 through high-order drainage tunnel barrel section 4, shared barrel section 5 other ends are provided with drainage tunnel outlet 6.
Said slag tip generally is arranged in the open relatively position, the exit or entrance of a clitch of natural cheuch, so that waste and guarantee the solid-holding amount.Stablize the gradient of its upstream and downstream operated by rotary motion 1:1.5 ~ 2.0, the storage capacity that takes on a certain scale in slag dam that artificial waste accumulation forms and the upper reaches cheuch simultaneously for the self structure that guarantees the slag field.
Drainage tunnel low level import 1 is that flood is a purpose with diluted debris flow in the conventional cheuch realize to drain, can be by general Diversion Tunnel or drainage tunnel design, but the tunnel base slope can suitably strengthen according to concrete orographic condition, is beneficial to the drainage of small-scale or diluted debris flow.The imperial new line form that adopts is arranged in the high-order import 2 of drainage tunnel; In case unconventional mud-rock flow (considering that mud-rock flow has unpredictability) takes place; And the mud-rock flow solid stops up drainage tunnel low level import 1, and pushing off the slag and the sediment effect of then utilizing slag tip to form precipitate the entrained solid deposit of disposable mud-rock flow in storehouse, the upper reaches, slag field; After realizing mud-water separation; After treating that follow-up flood rises to the high-order import 2 of drainage tunnel, utilize high-order import 2 safety of drainage tunnel to get rid of top layer flood or muddy water, avoid flood to cross slag body generation slag dam and burst and cause major accident.
The setting of high-order import 2 floor elevations of drainage tunnel; Can confirm according to the sedimentation elevation that a mud-rock flow solids all deposits in the storehouse; Floor elevation should be higher than sedimentation elevation, because a mud-rock flow macroanalysis usually can't be accurate, therefore still need leave the margin of safety of 1 ~ 2m.Said high-order drainage tunnel barrel section 4 should be positioned at drainage tunnel low level import 1 with low level drainage tunnel barrel section 3 and shared barrel section 5 tie points and silt up outside the influence basin.
Bank slope suitable location in the domatic or storehouse is laid special mud-rock flow deposit scarfing cinder passage at the slag dam upper reaches, guarantees that the scarfing cinder vehicle can get in the storehouse.When a mud-rock flow stops up at Ku Nei and draining hole, should behind flood, in time clear up deposit, recover the conveyance capacity of low level drainage tunnel, and vacate mud-rock flow solid deposit alluvial effective storage, guarantee to tackle possible mud-rock flow next time.
