Abstract
The utility model relates to a debris flow drainage structure combining an open channel and a box culvert, and aims to solve the problem of high jamming rate at a tunnel entrance position in an open channel and road box culvert connecting project. The debris flow drainage structure combining the open channel and the box culvert is simple in structure and convenient to construct. According to the technical scheme, a road is constructed at a ditch opening position with high debris flow occurrence rate, the box culvert traversing the road is arranged on the lower part of the road, and the open channel is connected to the front end of the box culvert. The debris flow drainage structure combining the open channel and the box culvert is characterized in that embankment slope concrete is arranged on the two sides of the open channel, is fixedly arranged on slopes on the two sides of the open channel through anchor bars, and is smoothly connected with the tunnel wall of the box culvert; and a bottom plate of the open channel is smoothly connected with a bottom plate of the box culvert.
Description
Technical field
The utility model relates to the debris flow drainage guide structure that a kind of open channel combines with box culvert.
Background technology
As shown in Figure 1 and Figure 2, in the debris flow drainage guide structure that most open channels combine with box culvert, box culvert 2 ' is positioned at road 1 ' bottom and crosses road 1 ', box culvert 2 ' front end connects open channel 3 ', open channel 3 ' both sides are the slope, slope and box culvert 2 ' advance hole shape in an angle, stay free face 4 ' so advance about the hole end at box culvert 2 ', this free face will be for the ratchel that is displaced downwardly to the hole, float the support that wood etc. provides downslide, thereby block the hole and stop up box culvert, dangerous situation when mud-rock flow or mountain torrents take place, occurs.
Summary of the invention
The technical problems to be solved in the utility model is: at the problem of above-mentioned existence, the debris flow drainage guide structure that provides a kind of open channel simple in structure, easy construction to combine with box culvert blocking problem occurs usually to solve in the engineering that open channel and highway box culvert join advancing openings position.
The technical scheme that the utility model adopts is: the debris flow drainage guide structure that a kind of open channel combines with box culvert, the position of easily sending out at mud-rock flow, the exit or entrance of a clitch is provided with road, the road bottom is provided with the box culvert that crosses road, the box culvert front end connects open channel, it is characterized in that: described open channel both sides are provided with pastes sloping concrete and is fixed in open channel two side slopes through dowel, pastes sloping concrete and box culvert hole smooth-going connection of wall; Described open channel base plate is connected with the box culvert base plate is smooth-going.
Upright slope is excavated in described open channel both sides.
The sloping concrete of described subsides is made upright slope.
The beneficial effects of the utility model are: open channel has solved preferably in the conventional engineering with the smooth-going structural arrangement form that is connected of box culvert and has advanced the situation that obstruction appears in the place, hole, investigation obtains this mentality of designing according to on-site actual situations, have certain practicality and novelty, for similar engineering provides a kind of new thinking.

The specific embodiment
As shown in Figure 3, Figure 4, present embodiment is the debris flow drainage guide structure that a kind of open channel combines with box culvert, the position of easily sending out at mud-rock flow, the exit or entrance of a clitch is provided with road 1, and road 1 bottom is provided with the box culvert 2 that crosses road 1, box culvert 2 be mainly used in the guide ditch water source, the mud-rock flow of letting out down, float wood etc.Box culvert 2 front ends connect open channel 3, and this open channel is mainly used in dredging down current, the mud-rock flow of letting out the exit or entrance of a clitch, float in the smooth-going inflow box culvert such as wood.Upright slope is excavated in these routine open channel 3 both sides, and obedient slope is built and is pasted sloping concrete 4 domatic, pastes sloping concrete 4 and also makes vertical surface, and adopt mode such as dowel be fixed in domatic on, open channel two side slopes are protected, guarantee runtime open channel both sides slope stability.Stay free face for avoiding advancing about the hole end at box culvert 2, pasting sloping concrete 4 must smooth-going the connection with box culvert 2 hole walls.Open channel 3 base plates also must with box culvert 2 base plates smooth-going linking.
The structure section of open channel 3 is led ability according to row and is calculated.The thickness that pastes sloping concrete 4 calculates according to its erosion resistibility to be determined.The physical dimension of box culvert 2 should be calculated definite according to amount of water to be discharged in the ditch.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
