Abstract
The utility model relates to a stride highway debris flow gully row and lead structure. The utility model discloses an aim at enlarging the mud -rock flow and excrete the space, reduce the resistance let out under the mud -rock flow. The utility model provides a: a stride highway debris flow gully row and lead structure, this drainage guide structural arrangement of is in the middle of original valley, and this original valley's downstream side violently has a highway, and build the highway bottom has the culvert, backfills the stone sediment between culvert top and the road surface, and the barricade has been built in the stone sediment outside, corresponding to the barricade below, be equipped with retaining wall in the culvert bottom, build the open channel and link up mutually with the culvert in original valley, the culvert use into the entrance to a cave as the starting point along the hole axis to both sides respectively the outer angle Q that expands be the loudspeaker form, the vertical sloping i of culvert edge hole axis is greater than vertical mean inclination of open channel section, the exit end of culvert and barricade binding site are with 1: N's slope upwards extends to when the wall outside. The utility model is suitable for a similar engineerings such as the mud -rock flow row of highway and debris flow gully joint part position leads.
Description
Technical field
This utility model is related to a kind of across Debris Flow along Highways ditches and arranges guide structure, is primarily adapted for use in highway and joins with debris flow gully
The debris flow drainage at position such as leads at the similar engineering.
Background technology
Highway in China prolongs continuous tens thousand of kilometer, in highway construction process, often runs into natural cheuch, if cheuch relatively deep or
Larger, possess the condition building bridge, then crossed over bridge；If cheuch is shallower or less, culvert and highway phase can only be passed through
Connect, this will run into the problem in the how smooth excretion of joining place for the mud-rock flow.By in recent years across the ruuning situation of highway culvert
Investigation, find most culverts concentrated down the mud-rock flow let out or fragmentary under the mud-rock flow let out block, 14.3% culvert is entering hole
Mouth is completely plugged, and 85.7% culvert is blocked at hole Nei Huochu hole, thereby it is ensured that mud-rock flow being capable of unobstructed row in culvert
The major issue let out is it is simply that how by the structure design of culvert, expanding mud-rock flow draining space, reducing and let out under mud-rock flow
Resistance.
Content of the invention
The technical problems to be solved in the utility model is：For above-mentioned problem, provide one kind across Debris Flow along Highways
Ditch arranges guide structure it is intended to expanding mud-rock flow draining space, reducing the resistance let out under mud-rock flow.
This utility model be employed technical scheme comprise that：A kind of across Debris Flow along Highways ditches arrange guide structure, this guide structure cloth
It is placed in the middle of original cheuch, the downstream Heng You highway of this original cheuch, highway bottom is built culvert, above culvert and road surface
Between backfill rock ballast, built barricade outside rock ballast, be provided with retaining wall foundation corresponding to below barricade, in culvert bottom, its feature exists
In：Build open channel and be connected with culvert phase in original cheuch；Described culvert is divided along hole axis to both sides with entering hole for starting point
It is in horn-like for not extending out angle Q °；Culvert along hole axis longitudinal slope i be more than open channel section longitudinal mean inclination；The outlet of culvert
End and barricade binding site are with 1：Ramping up of N extends to outside wall.
Described angle Q ° is 5～12 °.
Described longitudinal slope i is more than longitudinal mean inclination of open channel section.
Described slope N is 5～10.
This utility model beneficial effect is：This utility model is for solution across Debris Flow along Highways ditches row's guide structures are easily blocked
Lose a difficult problem for its function, provide a kind of across Debris Flow along Highways ditches to arrange guide structure, culvert is set to (along excretion direction) in level
It is set to tubaeform, and to the vertical diffuser of exit setting in the middle part of culvert, thus expanding mud-rock flow draining space, reducing
The resistance let out under mud-rock flow and the risk being blocked by mud-rock flow across highway culvert, have stronger specific aim and practicality.
Brief description
Fig. 1 is this utility model site plan.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is B portion enlarged drawing in Fig. 1.
Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment is that a kind of across Debris Flow along Highways ditches arrange guide structure, this guide structure cloth
It is placed in the middle of original cheuch 4, the downstream Heng You highway 101 of this original cheuch, highway bottom is built has culvert 2, above culvert
Backfill rock ballast 102 and road surface between, built barricade 3 outside rock ballast, be provided with retaining wall foundation corresponding to below barricade, in culvert bottom
3-1, is built open channel 1 in original cheuch 4 and is mutually connected with culvert 2；Culvert 2 is divided along hole axis to both sides with entering hole for starting point
It is in horn-like for not extending out angle Q °；Culvert 2 should be greater than longitudinal mean inclination of 1 section of open channel along longitudinal slope i of hole axis；Culvert 2
The port of export and barricade 3 binding site with 1：Ramping up of N extends to outside wall.
The specific embodiment of the present embodiment is as follows：
A. open channel 1：Based on the landform of original cheuch 4, carry out excavating the ditch bed longitudinal direction slope phase widened with original cheuch 4
Near open channel 1 so that in ditch mud-rock flow steadily return groove, it is to avoid multidirectional trickling；
B. culvert 2：The downstream Heng You highway 101 of original cheuch 4, builds, in highway bottom, the culvert being mutually connected with open channel 1
Hole 2, and backfill rock ballast 102 above culvert 2 and road surface between；This culvert, to enter hole as starting point, divides along hole axis to both sides
Not Kuo Zhang Q ° of certain angle (Q ° generally 5～12 °) so that culvert 2 is in horn-like in the plane；Guarantee that mudstone flows through open channel 1
After flowing into culvert 2 afterwards, traveling section constantly increases, the resistance effectively producing in the diffusion of release mud-rock flow；Culvert 2 is along hole axis
Longitudinal slope i be also mud-rock flow can smooth excretion key, generally, longitudinal slope i should be greater than the longitudinally average slope of open channel 1
Degree, such as has ready conditions, and increases the head fall of culvert 2 as possible, to improve impulsive force when letting out under mud-rock flow, increases the possibility passed through
Property；
The flow section of culvert 2 should determine come flow rate calculation according to mud-rock flow, the structure stress of culvert should combine with arrangement of reinforcement
The load COMPREHENSIVE CALCULATING such as the dynamic load of highway 101, backfill rock ballast 102 determine；
C. barricade 3：Investigation finds, most culverts 2 are blocked at hole Nei Huochu hole, for this phenomenon, in backfill
Barricade 3 is built in rock ballast 102 outside, is provided with retaining wall foundation 3-1 corresponding to below barricade, in culvert 2 bottom, in the outlet of culvert 2
End and barricade 3 binding site are with 1：Ramping up of N (N generally 5～10) extends to outside barricade 3, thus effectively increasing
The excretion section of mud-rock flow in culvert 2, releases the resistance producing in mud-rock flow diffusion it is ensured that mud-rock flow 2 will not in culvert
It is blocked.
