Description

The novel structure of preventing and treating of landslide transformant mud-rock flow
Technical field
The utility model relates to a kind of debris flow control works, particularly aspect the transformant mud-stone flow disaster of reply landslide, has proposed a kind of novel structure of preventing and treating.
Background technology
Generally speaking, the landslide is two kinds of different bulk movement types with mud-rock flow.Under the function influence of gravity, flowing pressure, earthquake or other certain power, along the slope or the geotechnical body of the downward integral slipping of side slope be called the landslide; Carry the flood stream of a large amount of solid detrital materials (piece stone, rubble, erratic boulder, cobble, sand) and clay matter fine clay, along steep ditch bed downstream the phenomenon of rapid movement be called mud-rock flow.
The landslide usually takes place under multiple factor effect, specific to each landslide its different main influencing factor and risk factor is arranged again.Landslide control is always taked the principal works measure to eliminate it to principal element or is controlled its influence, is aided with other measures simultaneously and carries out the comprehensive regulation, to limit other effect of factors.The principal element person who is landslide formation when the special growth of underground water for example should be main with mole drainage; If the river washes away, to make the landslide lose mechanical balance person should be main with protection against erosion, a retaining and mechanical balance measures such as loss of weight, presser feet then for hand excavation or preloading.Always preferentially adopt the measure of easy enforcement such as top drainage, underdrainage, loss of weight, presser feet and instant effect when having ready conditions.Landslide control also should be considered environmental protection and greening simultaneously, beautify, especially in the area, cities and towns.
The improvement of mud-stone flow disaster is in the formation, circulation, accumulation area at mud-rock flow; Take to administer accordingly engineering (like retaining, diversion works, block, support engineering, row leads, extradites engineering; The engineering and the slope protection works etc. of improving the soil stop becoming silted up), with the generation and the harm of control mud-rock flow.When the control of practical implementation mud-rock flow, should take domatic, raceway groove to take into account, the comprehensive treatment scheme that upstream and downstream is planned as a whole.Be main at the cheuch upper reaches to harness the river generally, middle reaches are main to control soil, and lead with row in downstream is main.Intercept water and the middle reaches bank protection etc. of blocking through the steady slope at the upper reaches, reduced the mud-rock flow solid matter, controlled debris flow scale, changed the character of debris flow body, the row who helps downstream leads effect, thus the harm of control mud-rock flow.In the engineering measure of implementing the mud-rock flow control, also should combine with biological control measure and other measures, could guarantee it like this and prevent and treat effective performance of benefit.
Landslide transformant mud-rock flow has special power conversion mode, its essence is the type of sports of rock fragment and muddy water amalgam under a kind of specific condition.Normally be with growth one landslide greatly at debris flow gully or its Zhigou source one, formation landslide, movable back type mud-rock flow, obstruction tap drain burst and form tap drain mud-rock flow harm downstream.Its formation and active procedure are very complicated, and Zhigou is a landslide type viscous mud-flow, often produces with cushioning effect.Therefore the transformant mud-rock flow that comes down is different with general landslide, mud-rock flow, and it has some characteristics of landslide and mud-rock flow concurrently, and landslide type mud-rock flow speed is fast, and impact force is strong, and is destructive big.The most common a kind of transformation mode is that both sides, tap drain road massif is high steep, receives effects such as formation lithology and regional tectonics, and raceway groove one sideslip slope is mass-sending property characteristic; The opposite side massif is then comparatively stable, and under the influence of unfavorable factors such as earthquake, heavy showers, landslide side massif slides on a large scale; But the landslide leading edge face absolutely empty very little, stopped by opposite ditch bank after, the landslide will be in nature presser feet state gradually; The landslide material is piled up in ditch, becomes the serious hidden danger of cheuch mud-rock flow.With respect to this type of landslide is whole after bringing back to life possible accumulation scope extensively, highly big; Act on and plan to build the block characteristics of the big and exit or entrance of a clitch dam foundation condition difference of thrust on the dam of debris flow gully, think that such dam of blocking not only need consider the percussion of upper reaches mud-rock flow residual substance, need consider to come down the influencing this and mainly threaten of accumulation body thrust and active pressure also.But, still lack effective Prevention Technique to the type mud-stone flow disaster at present.
Summary of the invention
The purpose of the utility model is the motion feature to landslide transformant mud-rock flow; Integrated control principle according to " blocking, arrange that to lead be main; be aided with the solid bed in steady slope "; A kind of novel structure of preventing and treating of the transformant mud-rock flow that comes down is provided, guarantees resident's in the basin the security of the lives and property, make prevention and cure project more reasonable, effective and economical.
The purpose of the utility model is achieved in that
The described novel structure of preventing and treating is made up of steel concrete antislide pile, contact beam, steel rope net, steel concrete link plate, wavy metal pipe culvert and six parts of mortar flag stone.
Described novel implementation method of preventing and treating structure is: divide three rows that the steel concrete antislide pile is set in position, the mud-rock flow exit or entrance of a clitch; Integral layout is space stake woods form, and each campshed connects through the contact beam between single stake inside and each campshed by quincunx interlaced arrangement; Hang steel rope net respectively after the stake of inboard two campsheds of ditch; The stake back of ditch oral-lateral one campshed hangs the steel concrete link plate, on the link plate wavy metal pipe culvert is set near the bottom of trench face of land, and all faces of land of stake of each campshed are carried out mortar flag stone and paved.
The beneficial effect of the utility model is: this structure can effectively be arranged rare property material of slide guide slope transformant mud-rock flow, reduces and eliminate the impact energy of mud-rock flow, and can tackle the threat of sudden Thrust of Landslide, improves the reliability of prevention and cure project.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is that sketch map is arranged in the control structural plan of the utility model;
Fig. 2 is that the control structure section of the utility model is arranged sketch map;
