Description
Technical field
The invention belongs to civil construction field, be specifically related to a kind of stackable agriculture arteries and veins practical weir.
Background technology
In some areas, NW China loess plateau, countless ravines and gullies, extreme dehydration, some areal rainfall depth only have 300～400 millimeter, and rainfall is concentrated, and evaporation capacity is up to more than 1500～2000 millimeters. Therefore, the precipitation during intensive precipitation is collected the main path being to solve water shortage problem, although prior art has some catchment methods, but the problem that all there is the DeGrain that catchments.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of simple in construction, cheap, use safety and the effective stackable agriculture arteries and veins practical weir that catchments.
For reaching above-mentioned purpose, the present invention provides following technical scheme:
A kind of stackable agriculture arteries and veins practical weir, including weir body, flood-relief channel, the height of described weir body is within 10 meters, described weir body can superposition, described flood-relief channel includes being arranged on the gap at body top, weir and being arranged on the gole at body back, weir, gole and weir body bottom junctions are provided with baffle wall style, when the surface distance of described gap and reservoir area precipitation silt is within 3 meters, one weir body of superposition on the body of described weir, described flood-relief channel is formed for digging out shape assembling reinforcement casting concrete again on sun-dried mud brick.
Further, described baffle wall style be provided opposite to waterwall, described waterwall, gole sidewall and baffle wall style composition stiling basin.
Further, the distance of described baffle wall style and described waterwall is 20 meters, and the height of described waterwall is 1 meter.
Further, described gap is arranged in the middle part of the body of weir, and described gap is the van-type structure by broad crested weir theory design.
Further, the surface of two side weir bodies of described flood-relief channel is provided with water-proof concrete slab.
The beneficial effects of the present invention is:
(1) height of each weir body is the highest less than 10 meters, according to storage capacity superposition weir body, it is ensured that the safety of weir body. NW China loess plateau province, the countless ravines and gullies in district, extreme dehydration some areas, collect 7,8,9 trimestral intensive precipitation in the drainage area of gully, solve water shortage problem, increase income.
(2) stop mud-rock flow, substantial amounts of precipitation will be stored in flood season, and alleviate river, river pressure, play good pondage capacity.
(3) weather and ecological environment are improved.
Accompanying drawing explanation
In order to make the purpose of the present invention, technical scheme and beneficial effect clearly, the present invention provides drawings described below to illustrate:
Fig. 1 is the side view of the present invention;
Fig. 2 is the flood-relief channel concrete frame figure of the present invention;
Fig. 3 is the axonometric chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As Figure 1-3, a kind of stackable agriculture arteries and veins practical weir, including the hydraulic structure that soil property weir body 1, flood-relief channel 2, baffle wall style 4, stiling basin 5 collectively constitute, it is mainly characterized by repeatedly building. For the safety of weir body 1, being designed as stackable weir body, a phase builds height from weir base to the Altitude control of gap 21 within 10 meters, when reservoir area sediment deposition reaches 7 meters, builds the weir body that the second layer is stackable, builds and highly also control within 10 meters. When sediment deposition reaches 17 meters, then build the weir body that third layer is stackable, build height 10 meters. By that analogy, the height needing to build is reached. Form the weir body of final height. If building weir body 3 layers stackable, the height from weir base to gap is exactly 30 meters. Can effectively control storage capacity by this method, it is ensured that weir body safe operation.
Flood-relief channel 2 includes the gap 21 being arranged on body top, weir and the gole 22 being arranged on body back, weir, gap 21 is van-type structure, the design of gap 21 is to calculate heavy rain crest discharge according to the computing formula of small watershed heavy rain crest discharge in national regulation, according to broad crested weir theory design. Gap 21 designs in the middle part of the body of weir, can in time substantial amounts of flood be drained when there is extraodinary flood.
Weir body 1 is for soil property and tamps. Digging out the shape of flood-relief channel on soil embryo, then assembling reinforcement forms concrete frame 3, on concrete frame 3, casting concrete forms the flood-relief channel 2 of armored concrete, the stable soil body can be played, the effect of fixing splash guard, stops infiltration through weir body, solves the difficult problem that earth dam breaks down because of piping. Being provided with water-proof concrete slab 6 behind firm weir on the surface of two side weir bodies of flood-relief channel 2, water-proof concrete slab 6 is that casting concrete is formed on water-proof concrete plate framework 7, serves the effect of protection weir body. When occurring that extra torrential rain forms exceptional flood peak, even if flood covers weir crest and produces incision without to weir body, thus ensure that the safety of weir body.
Go out gap 21 when flood and rush at the bottom of weir along gole 22; baffle wall style 4 is devised in the bottom on weir and the junction of gole 22; a high waterwall of 1 meter 8 is laid in the disappear position of power 20 meters of distance, forms a stiling basin 5, protection weir body 1 underlying security after the body of weir.
A kind of stackable agriculture arteries and veins practical weir can be built in units of unincorporated village, can build stackable agriculture arteries and veins practical weir in each the gully in vast mountain area, and water catching area just can be built more than 1 square kilometre. Weir body can be built in the riverbed of needs, all of rainfall is kept in valley, relatively flat mountain top, hill-side and gully here, and water is kept here, and soil is also kept here, does not allow relatively larger rainfall form flood. The soil of sheet can be produced by the deposition of a period of time, store substantial amounts of rainwater. When there is mud-stone flow disaster, it is possible to the solids by 90% stays reservoir area, is drained by Partial Flood. Because flood arrives the water surface that behind reservoir area, no longer flowing formation is large stretch of, after mud-rock flow arrives reservoir area, solids deposits rapidly in static water, when the water surface exceedes weir body gap height, allows unnecessary flood drain from gap. Reach to intercept the effect of mud-rock flow.Fundamentally solve the mud-rock flow erosion to massif. When weir body is increased to certain altitude, no longer there is mud-rock flow and landslide phenomenon. Fundamentally solve soil erosion problem. Substantial amounts of moisture is added to underground, improves level of ground water. Fundamentally solve earth dam and cause the global problem broken down.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
