Description
Technical field
The present invention relates to a kind of method and device for trees of blocking using drain cavern, belong to Controlling Debris Flow engineering technology neck
Domain.
Background technology
Mud-rock flow is in the dangerously steep area of the landform such as mountain area or other cheuch deep gullies, due to heavy rain, severe snow or other natures
The landslide that disaster triggers, carries a large amount of silts and stone and glides to forming mud-rock flow along massif.Such as August in 2010 7 days
The especially big mud-rock flow in Gansu Zhouqu County, the especially big mud-rock flow in the June in 2011 of Guizhou Province on the 6th Wangmo County and on June 28th, 2012 Sichuan it is cool
The especially big mud-rock flow in mountain has not only destroyed by rush of water the means of transportation such as highway, railway, bridge, and the safety in serious threat villages and small towns and campsite, gives
The people's lives and property brings about great losses.
The measure for administering mud-rock flow at present mainly has following several forms：First, the form using debris dam：To retain mud
Based on thick boulder in rock glacier, weaken the flood peak of mud-rock flow, debris dam can both intercept mud-rock flow, again can be during flood
Do not become silted up and bury by the silt in flood, reduce the workload of desilting, mud-rock flow is by developing into high sand-containing flood after debris dam, then leads to
Flume is crossed by flood carrying-off from the side, it is ensured that the safety of downstream building and the person.Second, drain cavern is added using dregs-blocking dam
Mode, blocked large particulate matter using dregs-blocking dam, mud-rock flow is changed into and only contained mud after fine grain flood using drain cavern
Rock glacier carrying-off, it is ensured that the safety of downstream building and the person；Third, add vertical shaft to add the form of drain cavern using dregs-blocking dam, using blocking
Slag dam is blocked large particulate matter, and mud-rock flow is changed into and only contains fine grain flood, is recycled vertical shaft to import mud-rock flow and is sluiced
Hole, it is ensured that the safety of downstream building and the person.
Thick trees are occurred frequently in landslide, even in shallow failure, in the low frequency or 200 that 100 years one meet
Under the extremely low frequency condition of raining that year one meets, substantial amounts of landslide may be induced, substantial amounts of trees is produced and drifts about in mudstone flow table
Face.Trees usually cause locally even in the motion of mud-rock flow in the blocking of large area.Such as Guizhou Province's on June 6th, 2011
The rainfall met in 200 years one occurs for Wangmo County, induces substantial amounts of shallow failure, substantial amounts of trees plug street, also plugged
The underground underground river of the km of Wangmo County town downstream 3, backwater is caused to flood the Le Wang towns in opening deep up to 5m.Cause
This trees is the biggest threat to result in blockage, and it is exactly one of the most important functions of engineering of blocking to intercept trees.
The content of the invention
It is an object of the present invention to provide a kind of method and device for trees of being blocked using drain cavern, with prevent drift wood with
Mud-rock flow mixes the blocking for causing drain cavern, failure, and prevents drift wood is final from crossing debris dam, threatens downstream building and the person
Safety, so as to overcome the deficiencies in the prior art.
The technical proposal of the invention is realized in this way：
The present invention it is a kind of using drain cavern block drift wood method be that this method includes drain cavern；The structure before drain cavern
One section of open channel is built, and constructs drift wood in open channel both sides and stops silt field, then beam slab of blocking, beam slab front end of blocking are set above open channel
For taper, the drift wood that drift wooden is directed to open channel both sides by the guide effect of taper stops silt field, prevents that floating wood blocks drain cavern,
Influence drain cavern and effect is led to the row of mud-rock flow.
In preceding method, groove is returned in the open channel front end provided with arc, returns groove to be directed at open channel front end by wooden is floated by arc.
According to the above method form it is of the invention it is a kind of be including to be located at sluicing using the block device of drift wood of drain cavern
The open channel of hole porch, open channel both sides are provided with drift wood and stop silt field, beam slab of blocking is provided with the top of open channel, and cone is in beam slab front end of blocking
Shape；The entrance of open channel returns groove provided with arc.
In aforementioned means, the taper angle of the beam slab front end of blocking is 60 °.
By adopting the above-described technical solution, the present invention is compared with prior art, the present invention is by increasing drain cavern open channel
The device of the trees of blocking of section, trees is trapped in drift wood and stop in silt field, while facilitate desilting, prevent from causing drain cavern to block,
Influence drain cavern and effect is led to the row of mud-rock flow.The present invention obtains significant effect with less input, has and widely pushes away
Wide meaning.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Mark in figure for：1- drain caverns, 2- open channels, 3- drift wood stop silt field, 4- blocks, and beam slab, 5- arcs return groove, 6- drifts
Wood.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples, but not as to any of the present invention
Limitation.
Embodiment
The method of a kind of drift wood of being blocked using drain cavern of the present invention, as shown in figure 1, this method includes drain cavern 1；Letting out
One section of open channel 2 is constructed before water hole 1, and constructs drift wood in the both sides of open channel 2 and stops silt field 3, then beam slab of blocking is set above open channel 2
4, the front end of beam slab 4 of blocking is taper, and the drift wood that drift wooden is directed to the both sides of open channel 2 by the guide effect of taper stops silt field 3, prevents
Only drift wood blocks drain cavern, influences drain cavern and leads effect to the row of mud-rock flow；Groove 5 is returned in the front end of open channel 2 provided with arc, passes through arc
Groove 5 is returned to be directed at the front end of open channel 2 by wooden is floated.
A kind of blocked using drain cavern of the invention formed according to the above method floats the device of wood, as shown in figure 1, the dress
The open channel 2 including being located at the porch of drain cavern 1 is put, the both sides of open channel 2 are provided with drift wood and stop silt field 3, and the top of open channel 2 is provided with beam slab of blocking
4, the front end of beam slab 4 of blocking is taper；The entrance of open channel 2 returns groove 5 provided with arc；The taper angle of the front end of beam slab 4 of blocking is 60 °.
The course of work and principle of the present invention
When mud-rock flow occurs, substantial amounts of silt particle, stone are mingled with some trees as mud-rock flow is let out along under hillside together,
Due to the substantial amounts of water of content in mud-rock flow, usual trees are swum on mud-rock flow, therefore the trees floated also referred to as float
Wood.Instantly after the mud-rock flow let out returns groove 5 into arc, mud-rock flow surface is floated over into open channel 2 in the case where arc returns the guiding of groove 2
After drift wood 6 runs into beam slab 4 of blocking, for the tapered of 60 ° of angle, drift wood 6 is split to the drift of the both sides of open channel 2 for the front end of beam slab 4 of blocking
Wood stops silt field 3；The silt particle and stone of mud-rock flow bottom then enter drain cavern 1 by open channel 2.Drain cavern is blocked so as to prevent from floating wood
1, to ensure the unimpeded of drain cavern 1.The present invention is in low frequency even extremely low frequency（Such as 100 years or 200 years one chances）Rainfall
When, a wide range of substantial amounts of landslide is produced, when being let out under the substantial amounts of floating trees of mud-rock flow carrying, can effectively intercept and dredge drift wood
Stop silt place into drift wood, prevent that floating wood enters drain cavern, to ensure the unimpeded of drain cavern, the row for improving mud-rock flow leads.
