Description
Technical field
The utility model belongs to debris flow technical field, is specifically related to one and draws anchor formula mud-rock flow to block row's structure, be mainly applicable to the improvement of middle-size and small-size diluted debris flow disaster.
Background technology
China's mountain area area is large, debris flow gully and potential debris flow gully widely distributed.Annual heavy rain season, mud-stone flow disaster frequently occurs.Particularly western China, the people life property loss that causes of mud-stone flow disaster is quite serious in recent years.In order to alleviate the frequent mud-stone flow disaster occurred, people take prophylactico-therapeutic measures miscellaneous.Single from initial engineering type, it is main for leading facility, check dam, entity dam and Bao Kan mainly with the row of building, engineering norm for civil defense is general lower, the studying and combating level of mud-rock flow significantly improves finally, start debris flow planning and the design of system of formulating, means of prevention becomes increasingly abundant, and defines many model about synthesis control having surely, block, arrange, stop silt combination gradually.
Current gravity blocking dam and concrete grating dam are the normal two kinds of form of structure adopted in debris flow control works.Gravity blocking dam carrys out by the weight of self impact that mud-rock flow is kept out in front, and suffered impact force is very large, therefore sectional dimension is very large, need consume its normal sediment trapping function of larger manpower, material resources and financial resources guarantee; And water permeable ability is poor, later stage draining and anticorrosive outstanding problem, desilting difficulty is larger.Concrete grating dam blocks, arranges and have both, becoming the whole of entity gravity dam in the past blocks as part is blocked, the larger solid matter of major part in mud-rock flow is deposited in storehouse, and most of current are overflowed, let out the density of mud-rock flow, flow and scale under can reducing, reduce the degree that downstream suffers state of debris flow disasters.In order to resist the impact of mud-rock flow fluid and ratchel, often with the lateral rigidity of heavy in section structural element for cost enhanced grid dam during design, be the stability that cost ensures crib dam with buried (half that about pile body is long) and space structures arrangement form.Therefore, under the prerequisite considering economy, stability becomes the deadly defect that concrete grating dam utilizes.
The difference such as mud-stone flow disaster scale and character in basin, the prophylactico-therapeutic measures taked and the preventive works of building respectively are had any different, in order to reach the object alleviating mud-stone flow disaster to greatest extent, dissimilar preventive works need various types of control structure conbined usage.Therefore, debris flow structure should towards the future development of lightness and multifunction.
Summary of the invention
The purpose of this utility model solves current control structure heaviness, and water permeability is weak, the problem of poor stability.
The utility model is that one draws anchor formula mud-rock flow to block row's structure, is made up of grid, counterfort 1, base plate 2 and drag-line 3; Grid is connected and composed by grid beam 4, grid post 5 and foundation pile 6; Grid beam 4 is connected with grid post 5 square crossing, and grid post 5 build-in is in foundation pile 6, and foundation pile 6 is embedded in stable firm hard formation 10; Grid post 5 is connected with counterfort 1, and counterfort 1 is built below in integrally with base plate 2, base plate 2 is close to ditch bed 11; Drag-line 3 is through the preformed hole 7 offered in counterfort 1, and drag-line 3 leading portion ground tackle 9 is anchored on grid, builds to form enlarged body 8 and be anchored at stablize hard stratum 10 at the back segment of drag-line 3.
The invention has the beneficial effects as follows: this utility model structure is slim and graceful, and the row's of blocking ability is good and stability is strong.Grid and counterfort, base plate, drag-line combines and greatly improves the stability of structure; Grill space is adjustable, achieves the target that mud-rock flow blocks row's combination; If grid adopts shaped steel, structure assembly and disassembly ability is strong; The enlarged body that drag-line connects can ensure the resistance to overturning of mud-rock flow cell structure, can avoid again the waste using heavy in section, buried structure is brought; Counterfort makes the uniform force of cell structure, and has the effect that protection drag-line washes out and shunts.Along with the increasing of Accumulation In Debris-flow of this structure intercepts, base plate ballast increases, and enlarged body buried depth is darker, and the anchored force that drag-line can provide increases, and structure will make stability sharply decline because of increasing of deposit.This structure can reach dependable performance, use safety, easy construction, cheap general effect.
