Description

A kind of row's selvage guide interposed structure of debris flow gully

Technical field

The utility model relates to a kind of row's selvage guide interposed structure of debris flow gully.Be applicable at the exit or entrance of a clitch that mud-rock flow is easily sent out and arrange that road traffic reaches the engineering of the drainage that combines with traffic.

Background technology

In most of engineerings, the exit or entrance of a clitch of easily sending out at mud-rock flow does not generally arrange road traffic, and the thing source of mud-rock flow moves down the drainage system of the bottom that may block the road on the one hand, avoids the road that destroys by rush of water that moves down of mud-rock flow on the other hand, and influence is normally current.

Yet for some engineering, because some special requirement of shelter are arranged, in the time of must road traffic being set at the exit or entrance of a clitch that mud-rock flow is easily sent out, the designer need take all factors into consideration design scheme, and the risk that its mud-rock flow that may let out is down brought drops to minimum.

Summary of the invention

The technical problems to be solved in the utility model is: at the problem of above-mentioned existence, a kind of row's selvage guide interposed structure of debris flow gully is provided, lead problem to solve the mud-rock flow exit or entrance of a clitch and the ditch water treatment of traffic route binding site and debris flow drainage preferably, mud-rock flow may be let out the risk of bringing down be reduced to minimum.

The technical scheme that the utility model adopts is: a kind of row's selvage guide interposed structure of debris flow gully, the exit or entrance of a clitch of easily sending out at mud-rock flow is furnished with traffic route, comprise roadbed and Irish bridge, it is characterized in that: the traffic route downstream is concrete guard wall, concrete guard wall upstream backfill rock ballast material forms roadbed, and the roadbed end face arranges Irish bridge; Position, exit or entrance of a clitch excavation is useful on dredges down the current of letting out the exit or entrance of a clitch, the open channel of mud-rock flow, and open channel arranges downwards along physical features and the concrete box culvert through the traffic route bottom passes traffic route.

Described open channel side has been built and has been led wall, and this is led wall and is arranged at the lower side of exit or entrance of a clitch physical features, leads the wall base plate and is fixed on the basement rock through dowel.

Described open channel and concrete box culvert connecting portion arrange the steel trashrack.

Concrete floor has been built in described open channel bottom, and this concrete floor is connected with the concrete box culvert base plate is smooth-going.

The Irish bridge at concrete box culvert top is the high funnel-forms in middle low both sides.

The beneficial effects of the utility model are: box culvert and traffic route structure combining arrangement form that the utility model row leads mud-rock flow have overcome the problem of easily sending out mud-rock flow exit or entrance of a clitch layout road traffic difficulty, solve the mud-rock flow exit or entrance of a clitch and the ditch water treatment of traffic route binding site and debris flow drainage preferably and lead problem, mud-rock flow may be let out the risk of bringing down be reduced to minimumly, take into account debris flow gully internal drainage facility simultaneously.

The specific embodiment

As Fig. 1 ~ shown in Figure 3, present embodiment is led situation about combining at current guide in the debris flow gully with debris flow drainage, proposes box culvert and traffic route structure combining arrangement form that a kind of row leads mud-rock flow.The exit or entrance of a clitch of easily sending out at mud-rock flow is furnished with the traffic route that comprises roadbed 2 and Irish bridge 3, the traffic route downstream is concrete guard wall 1, concrete guard wall upstream backfill rock ballast material forms roadbed 2, roadbed upstream side concreting spats 9, and roadbed 2 end faces arrange Irish bridge 3.

The traffic route bottom is provided with concrete box culvert 4, and this box culvert is horizontally through traffic route, the water source in the main guide ditch.Concrete box culvert 4 front ends excavations open channel 5, open channel are mainly dredged down the current of letting out the exit or entrance of a clitch, mud-rock flow etc., make it concentrated and let out under smooth-going.Open channel 5 sides are provided with leads wall 7, and this is led wall and mainly is arranged on the lower side of exit or entrance of a clitch physical features, leads wall 7 base plates and is fixed on the basement rock through dowel, covers open channel 5 when preventing from letting out under the mud-rock flow to the exit or entrance of a clitch, flows into the low position of physical features, this position important building of crisis.

At concrete box culvert 4 position that is connected with open channel 5 steel trashrack 8 is set in the present embodiment, its major function be prevent in the ditch flushing cinder, float wood etc. and enter box culvert it is stopped up.The Irish bridge 3 at concrete box culvert 4 tops is the high funnel-forms in middle low both sides; when its major function is stopped up the bottom box culvert for the mud-rock flow of letting out instantly; alluvial can be concentrated from this position at this mud-rock flow drain to the downstream, thus the safety of not crisis important building.

Open channel 5 is difficult for excavating dark in this example, and its concrete floor 6 must get final product with smooth-going joining of box culvert base plate.The structure section of concrete guard wall 1 must satisfy homeostasis and guarantee that the mud-rock flow of letting out down can not overflow the top and get final product.The physical dimension of concrete box culvert 4 should be calculated definite according to amount of water to be discharged in the ditch, does big under the situation of having ready conditions as far as possible.The requirement that the recessed degree of depth of Irish bridge 3 must satisfy unobstructed, the concentrated row down of mud-rock flow and be open to traffic safely.

The concrete job practices of present embodiment:

1), by in-site measurement, determine the position, control point of each several part structure, carry out the excavation of 5 sections of open channels earlier, open channel 5 is difficult for excavating dark, guarantees that its base plate must get final product with smooth-going joining of box culvert base plate;

2), carry out open channel 5 sides and lead the construction of wall 7, lead wall 7 bases and must be located on the basement rock, for guaranteeing to lead the stable of wall under the mud-rock flow effect, lead the wall base plate and dowel can be set be fixed on the basement rock;

3), carry out the construction of concrete box culvert 4, the physical dimension of box culvert should be calculated definite according to amount of water to be discharged in the ditch, does big under the situation of having ready conditions as far as possible;

4), be connected with the open channel 5 steel trashrack 8 at position of box culvert is installed, stablize for guaranteeing it, at steel trashrack 8 trailing edges enough stressed braced structuress must be set;

5), carry out the construction of Irish bridge 3; this road surface is middle low, when the funnel-form that both sides are high, its major function are stopped up the bottom box culvert for the mud-rock flow of letting out instantly; alluvial can be concentrated from this position at this mud-rock flow drain to the downstream, thus the safety of not crisis important building.
