Description
Technical field
The utility model belongs to mountain torrents debris flow technical field, and in particular to a kind of blocking dam for mud-rock flow.
Background technology
The landform quacification complexity mud-rock flow in our mountain areas is the main address for threatening the mountain area people normally to produce, live
One of disaster.Influenceed by factors such as earthquake, extreme weather conditions, the frequency more and more higher of mountain area debris flow, it is frequently living
The dynamic substantial amounts of solid matter of mud-rock flow downstream transport, property and safety to people cause great infringement.
At present, the Main Means for preventing and treating mud-rock flow are to establish mud-rock flow blocking dam, and the method for intercepting mud-rock flow mainly has two
Kind, one kind is to stop mud-rock flow completely using debris dam storehouse, and a kind of is the impulsive force for being buffered using splitter box mud-rock flow, so
And due to sudden and mud-rock flow grade the certainty that mud-rock flow occurs, single debris flow means are difficult to meet not
Debris flow with degree is administered, and mud-rock flow is mingled with substantial amounts of stone and trees in motion process, it is easy to conventional
The dredging pipeline of mud-rock flow blocking dam block, cause the heap of mud-rock flow, make mudstone when dam body is destroyed by rush of water by mud-rock flow
The energy moment increase of stream, increase the destruction ability of mud-rock flow, so that mud-rock flow blocking dam turns into the accomplice of mud-stone flow disaster,
Therefore, existing mud-rock flow blocking dam can not meet the needs that debris flow is administered.
Utility model content

Compared with prior art, the beneficial effects of the utility model are：Mud-rock flow can be slowed down to dam body by stone battle array
Impact velocity, the extent of damage of dam body, Shi Zhen and the stone and trees that post can stop that volume is larger in mud-rock flow of blocking are reduced,
Mud-rock flow is just blocked in the front of dam body, while reduce the risk that culvert is blocked on dam body, increase dam body is to small-sized mud
The interdiction capability and dredging ability, overflow segment of rock glacier can make macrosolifluction have enough spaces to circulate, and reduce mud-rock flow
Infringement to dam body, the first obstruction body in overflow segment can reduce the flow velocity of mud-rock flow, while reduce mud-rock flow from dam body stream
Can be disperseed by the flow direction of mud-rock flow, drop the impulsive force of mud-rock flow, the utility model for second impact for stopping body, splitter box when lower
It is vdiverse in function, different brackets and the mud-rock flow of scale can be dealt with, use range is wide, prevents the significant effect of mud-rock flow.
Brief description of the drawings
Fig. 1 is a kind of structural representation of blocking dam for mud-rock flow
In figure：1- dam foundation plinth, 2- stone battle arrays, 3- block post, 4- spacers, and 5- first stops body, 6- guiding gutters, 7- tap holes,
8- splitter boxs, 9- second stop body, and 10- reinforces section, 11- culverts, 12- overflow segments.
Embodiment
Embodiment 1, as shown in Fig. 1 structures, a kind of blocking dam for mud-rock flow, including dam body and dam foundation plinth 1, dam body
Front is provided with Shi Zhen 2, and Shi Zhen 2 is marble stone battle array 2, and post 3 of blocking is provided between Shi Zhen 2 and dam body, and post 3 of blocking is circle
Block post 3, Shi Zhen 2 and post 3 of blocking are cast on dam foundation plinth 1 by cement, the distance between Shi Zhen 2 and dam body for 100 meters ~
150 meters, it is ~ 100 meters that block the distance between post 3 and dam body, which are 60 meters, and the height of Shi Zhen 2 height and the first obstruction body 5 is big
In the height of culvert 11, Shi Zhen 2 and post 3 of blocking can reduce impact dynamics of the mud-rock flow to dam body, while can be mud-rock flow
In the volume that is mingled with stopped compared with ratchel and trees, reduce the blocked risk of dam body culvert 11, strengthen the excretion of dam body
Ability, the stone retained by stone battle array 2 and post 3 of blocking can be formed with trees together with stop barrier, follow-up mud-rock flow is carried out
