Description
Technical field
The mud-rock flow for choosing streaming separation of solid and liquid the invention belongs to debris flow field more particularly to a kind of energy dissipating is blocked knot
Structure further relates to its construction method.
Background technique
Mud-rock flow refers in mountain area or other cheuch deep gullies, the dangerously steep area of landform because heavy rain, severe snow or other from
The landslide of right disaster initiation and the special mighty torrent for carrying a large amount of silts and stone.Mud-rock flow has sudden and stream
The features such as fast fast, flow is big, and matter content is big and destructive power is strong.Mud-rock flow, which occurs, can usually destroy by rush of water the means of transportation such as road and rail
Even villages and small towns etc., bring about great losses.
China's mud-rock flow breaks out the excitation that rainfall is mainly concentrated by continuous rainfall, heavy rain, especially extra torrential rain.Cause
This, the temporal regularity that mud-rock flow occurs be it is consistent with rain time rule is concentrated, have apparent seasonal.It typically occurs in
Rainy summer and autumn.The rainfall of the southwests such as Sichuan, Yunnan focused mostly in the 6-9 month, therefore, the mud-rock flow of southwest it is more
Occur in the 6-9 month；And the Northwest's rainfall focused mostly at 6,7,8 three months, especially 7, the concentration of rainfall in 8 two months, heavy rain is strong
Degree is big, therefore the Debris Flow of the Northwest is raw at 7,8 two months.According to incompletely statistics, the mudstone in the two months occurs
Stream disaster accounts for about 90% or more of this area's whole mud-stone flow disaster.
According to statistics, China has 29 provinces (area), 771 counties (city) just by the harm of mud-rock flow, every year on average mud-rock flow
The frequency that disaster occurs is 18 times/county.At present China oneself find out that the cities and towns above county level by state of debris flow disasters or threat have 138
It is a, the western provinces and regions such as Gansu (45), Sichuan (34), Yunnan (23) and Tibet (13) are mainly distributed on, by mud-rock flow
Harm or the township level cities and towns quantity threatened are bigger.
Structure of blocking is the solid matter and heavy rain, flood runoff to control mud-rock flow, weaken mud-rock flow flow, under let out
Amount and energy, to reduce mud-rock flow washing away, hit and becoming silted up and the engineering measure of harm such as bury to downstream architectural engineering.It is main at present
Structure of blocking have column slag dam, storage silt field, retaining engineering, cut big vast engineering etc..However, their function is all relatively simple, often
The effects of only individually considering the flow velocity for reducing mud-rock flow, retaining mud-rock flow.Due to mud-rock flow mainly include solid stone and
The silt of fluid, thus they hazard ratio it is common flood it is bigger, can reduce mud-rock flow if separating stone with silt
Harm.Therefore, the flow velocity of mud-rock flow can be reduced by being badly in need of one kind now, and can separate the mudstone of the stone and silt in mud-rock flow
Stream is blocked structure.
Summary of the invention
For the problems in background technique, the purpose of the present invention is to provide the mudstones that streaming separation of solid and liquid is chosen in a kind of energy dissipating
Stream is blocked structure and its construction method, it can not only reduce the impact energy of mud-rock flow, but also can separate the stone in mud-rock flow
Block and silt are of great significance to prevention and treatment mud-stone flow disaster.
In order to solve the above-mentioned technical problem, the mud-rock flow that streaming separation of solid and liquid is chosen in a kind of energy dissipating of the present invention is blocked structure use
Technical solution: block wall and energy dissipating separated structure including choosing stream, the stream coping of blocking of choosing is provided with and chooses stream arc knot
Structure, wall rear portion are provided with several protrusions, and waste tire is provided in the protrusion, is filled with inside the waste tire broken
Stone, the waste tire surface are provided with steel wire, and the steel wire is fixed on the wall with rivet；The energy dissipating separated structure
Inside be cavity structure, top is provided with several energy dissipating teeth and several sorting holes, and bottom is slope structure.
Preferably, the protrusion is cylinder, and size is consistent with the inner cylindrical cavity of the waste tire.
Preferably, the energy dissipating separated structure choose stream block wall downstream at two rows are at least set.
It blocks the construction of structure another object of the present invention is to provide the mud-rock flow that streaming separation of solid and liquid is chosen in a kind of energy dissipating
Method, method includes the following steps:
S1 it) in the mountain valley for needing to prevent and treat mud-rock flow, according to design requirement, builds and chooses stream and block wall；
S2) choose stream block wall top portion setting choose stream arcuate structure, several protrusions are set after wall；
S3) waste tire is installed in protrusion, filling rubble in inside is covered on the surface of waste tire with steel wire, uses riveting
Steel wire is fixed on the wall by nail；
S4) choose stream block wall downstream at the row's of building energy dissipating separated structure, the bottom of energy dissipating separated structure is set as slope surface knot
Structure, top are provided with energy dissipating tooth and sorting hole, and two rows are at least arranged in energy dissipating separated structure.
Compared with prior art, it beneficial effects of the present invention: is blocked wall design using stream is chosen, is set in the protrusion on its surface
It is equipped with waste tire, using the elastic characteristic of tire, when on mud-rock-flow-impact to waste tire, it can generate flexible deformation,
So that mudstone stream energy is decayed, reduces debris flow velocity；Using energy dissipating separated structure, its top energy dissipating tooth secondary can be cut
Weak mudstone stream energy, sorting hole can separate the silt of stone and fluid, reduce the disaster of mud-rock flow；In addition, the structure building
Quickly, easy for construction, the advantages such as maintenance cost is low.
