Abstract

A sinking plate for diversion and sand barrier is composed of main plate inclined to downstream direction and supporter of main plate. When said sinking plates are parallelly arranged to water stream at both sides of river, the energy of water stream is used without external energy. Its advantages are high dredging effect and low cost.

Description

Sunk slab for directing water flow and stopping sand

The present invention relates to the special equipment of riparian work, particularly relate to a kind of being suitable in the rivers, the sunk slab for directing water flow and stopping sand that use in the downstream.

In the rivers, downstream river course is generally mild, than falling deficiency, base layer stream is pressed little, so the sediment carrying capacity deficiency, so that the silt that is detained deposits year by year and increase, the cross section, riverbed dwindles, and develops into wide shallow shape at random gradually, has lost normal flood discharge, sediment transport, shipping ability.Therefore, silt is controlled in the river course has become one of needing to be resolved hurrily in the riparian work of task.

The existing silt measure of generally adopting of controlling has two.The one, increase anti-general river levee, two are to use and comprehensively drag the silt ship to dig sand to transport.These two kinds of methods all can not solve the problem of flood discharge, transportability of sediments deficiency at all, and expensive big, speed is slow.

The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of strength that can compile current itself not need the sunk slab for directing water flow and stopping sand of external energy.

For this reason, sunk slab for directing water flow and stopping sand of the present invention comprises:

(a) mainboard of one or more amalgamations, said mainboard are Parallel to the flow direction and are obliquely installed, and the lower end of said mainboard contacts with sealing at the bottom of the riverbed;

(b) one or more holder devices, support and fixing said mainboard back in, the upper part, the height of said holder device makes said mainboard and riverbed angulation meet the husky requirement of water conservancy diversion retaining, and changes according to the gradient of position.

According to the preferred embodiments of the present invention:

(a) the mainboard lower end is a sharp edge type;

(b) an elastic sponge body is fixed in the mainboard lower end, to realize the sealing contact;

(c) mainboard is two plate sectional mo(u)lds;

(d) mainboard is three plate sectional mo(u)lds;

(e) mainboard and river bed angle approximate 45 °.

(f) mainboard and river bed angle and angle of gradient sum the best are 65 °.

In order to understand essence of the present invention better, describe the preferred embodiments of the present invention with reference to the accompanying drawings in detail, wherein:

Fig. 1 is the lateral view that expression has the heavy plate of the present invention of the support that single mainboard is connected with fourth of the twelve Earthly Branches groove;

Fig. 2 is that the lateral view of mainboard and the river bed angle of cut and gradient relation is illustrated in the heavy plate of expression monomer;

Fig. 3-1 and 3-2 are respectively the oblique views of right side shown in Figure 1 type and the heavy plate of left side type;

Fig. 4 is the lateral view of the heavy plate of two plate sectional mo(u)lds;

Fig. 5 is the lateral view of the heavy plate of three plate sectional mo(u)lds;

Fig. 6 is the lateral view at the heavy plate junction surface of expression sectional mo(u)ld;

Fig. 7 is that the D of Fig. 5 rectifies view.

Identical or corresponding parts are represented with identical label in the accompanying drawing.

Fig. 1 and Fig. 3-1 and Fig. 3-2 are respectively the lateral view and the oblique views of heavy plate of the present invention.Wherein, mainboard 1 is all formed by concrete prefabricated with support 2.Can be provided with one in the middle and upper part, the back side of mainboard 1 and connect fixing fourth of the twelve Earthly Branches groove 10 so that mainboard 1 can be fixed together with support 2 with support 2 upper ends.Support 2 works to support mainboard 1.By Fig. 3-1 and Fig. 3-2 as can be seen, support 2 is respectively established two.Support 2 lower ends are provided with the pin leaf 21 of stream inclination downstream, so that heavy plate is more stable between operation.Mainboard 1 Parallel to the flow direction inclination side is provided with, and forms the top and bottom of mainboard 1.The lower end of mainboard 1 is sharp edge type.Waterproof for making between mainboard 1 and the river bed 4, can fix an elastic sponge body 3 in the lower end of mainboard 1 by screw rod.Under the support of support 2, mainboard 1 tilt downstream a side of 45 ° of mainboards 1 of angle α ≈ of being become with the end 4 present turn or under turn tooth shape, be that right side type or left side shape are decided on heavy plate.Fig. 3-1 is the right side type; Fig. 3-2 is the left side type.

Fig. 2 is the diagrammatic side view of expression angle α and gradient relation.Mainboard 1 wherein and support 2 are fixed together by screw rod 5 assemblings.The length of support 2 is by mainboard 1 and the angle α at the end 4 ₁And base slope gradient α ₄Size decision.As seen from Figure 2, angle α ₁Reduce to 20 °, corresponding gradient α by 45 ° ₄Rise to 45 ° by 20 °, be inverse relation between the two, but at α ₁+ α ₄Best results in the time of=65 °.For example, work as α ₄In the time of=45 °, α then ₁=65 °-45 °=20 °.At this moment, available the shortest support 2 _ShortSupport mainboard 1.

For deep water stream, available two, three or the serial connection amalgamation of polylith mainboard and with two, three or more stent support mainboard.Shown in Figure 4 is the heavy plate that two plates, double bracket piece together.Wherein mainboard 1 _Down, 1 _OnBe supported on short, long two supports 2 respectively _Short, 2 _LongOn.And, only 1 _DownThe bottom elastic sponge body 3 is set.

Fig. 5 and Fig. 7 represent the lateral view and the elevation of the heavy plate of three plate amalgamation frame types respectively.Wherein, the back side, upper end of next piece mainboard is hook-shaped, and the lower end of last two mainboards is " Y " shape.Three mutually nested interlockings of mainboard also all are attached on the support 2 successively admittedly, and support 2 is by two sloping framves of the basic symmetry that is " going into " shape and a crossbeam formation of fixing two sloping framves.Fix by screw rod between beam, the frame.The heavy plate of three-plate type is applicable at deep water and flows anxious position retaining sand.

Fig. 6 represents the lateral view of two mainboards at place, amalgamation junction surface.The effect of each parts and label will not be given unnecessary details here with in the past described identical among Fig. 5.

In use, the needs segmentation parallel connection of a plurality of sunk slab for directing water flow and stopping sand of the present invention according to actual conditions is distributed in the current of both sides, wide shallow river course bed.The mainboard that tilts slows down the current decompression and stagnates carrying in side bed deposition, and poly-pressure of water conservancy diversion return strand in the middle part, riverbed, has strengthened carrying, transportability of sediments, has played the effect on lasting brush groove silt beach, is convenient to administer effectively rivers silt, dredging channel.And sunk slab for directing water flow and stopping sand of the present invention has only called the poly-energy of pressing of current itself, does not need external energy, and is therefore expensive few, the efficient height.If " water power deposit scouring device for river " that be placed on the middle part, riverbed of this equipment and inventor's invention is used, then the effect of sand control will be better.
