Abstract
The invention relates to a device for preventing a river bank from being washed out by river water. The invention relates to river treatment technology. A plurality of triangular prisms and trapezoid pillars are inserted into the river bank; the straight surface of each triangular prism is at an angle of 900 degrees with the river surface; the big surfaces of the triangular prisms and the trapezoid pillars are towards the river bank and the small surfaces of the triangular prisms and the trapezoid pillars are towards a river; and the distance between every two triangular prisms or every two trapezoid pillars can be meters to tens of meters according to the condition of flow and washout of the river water. The device is characterized in that due to the action of the triangular prisms and the trapezoid pillars, in the flowing process, the river water impacts the triangular prisms and the trapezoid pillars without impacting the river bank, so that soil sand on the river bank cannot be washed away.
Description
Technical field
The present invention relates to the river management technology.
Background technology
At the embankment of rivers, wash away down at river, often can cause the native sand of embankment to be flushed away, even the dike that collapses, because the unstability of river, during river and large, Shi Erxiao, particularly when Flooding, the impact of river is larger.Common people's layer overlay slabstone on the embankment slope, but often river can fall the silt underwashing under the slabstone, causes subsiding of slabstone.
Through the patent searching document, discovery has the CN01805787.X patent " to be used for the method for soil erosion control and shore protection work and to be used for soil erosion control and the anti-structure of bank ", propose " a kind of method for the Soil Erosion Control fortification, its can by do not need with wirerope and steel mesh a large amount of construction labours and significant cost prevent the valley bed and bank avoid the erosion of mountain torrents.The method may further comprise the steps: at least two vertical cables (1) are fixed on the fixture (2) directly or indirectly; By the horizontal cable (5) that uses at least two suitable distances in interval that many vertical cables are fixed to one another; Throw the net (3) anchoring firmly by the horizontal cable or the anchoring cable that use described vertical cable and be connected on these vertical cables with at least two, wherein the number of this net (3) is corresponding to the number of horizontal cable, usually make these nets relative with current, thereby these nets are arranged in the mountain torrents on the direction from the upstream side to the downstream with suitable interval.”
Summary of the invention
The objective of the invention is: propose a kind of device that prevents the riverbank to be washed away by river.
The technical solution adopted in the present invention (or its design principle) is: scheme one: make triangular prism (2), several, as shown in Figure 1.Triangular prism (2) overlook (or looking up) is leg-of-mutton, preferably: right-angled triangle (it is the triangle at right angle that an angle is namely arranged); Be also referred to as: isosceles triangle (i.e. two triangles that the limit equates), as shown in Figure 2.Triangular prism (2) can be all equally large up and down, also can be big end down, as shown in Figure 3.Insert several triangular prisms (2) on the riverbank, large one towards the riverbank, and little one towards the river; Facing directly towards the upper reaches, river of triangular prism (2), the inclined-plane is dirty towards the river, and facing directly with river surface of triangular prism (2) becomes 90 basically
0The angle.Distance between two triangular prisms (2) can be several meters to tens meters, as shown in Figure 4 according to the situation that river flows and washes away.
Scheme two: make trapezoidal column (5), several, as shown in Figure 5.Trapezoidal column (5) can be all equally large up and down, also can be big end down, as shown in Figure 6.Insert several trapezoidal column (5) on the riverbank, large one towards the riverbank, and little one towards the river, as shown in Figure 7.
Characteristics of the present invention are: because the effect of triangular prism (2), trapezoidal column (5) is arranged, when river flowed, river impacted triangular prism (2), trapezoidal column (5), does not impact the riverbank, just can not cause the native sand on riverbank to be flushed away; And because triangular prism (2), trapezoidal column (5) have been arranged, the silt in the river is lived by triangular prism, trapezoidal column shelves, is deposited on (being the place, riverbank) in triangular prism (2), the trapezoidal column (5), has increased the silt on riverbank, as shown in Figure 4.

The specific embodiment
Embodiment 1: 1～4 this embodiment is described by reference to the accompanying drawings.(1) inserts several triangular prisms (2) on the riverbank, and overlooking of triangular prism (2) is equilateral triangle (namely the angle at two oblique angles is 45 degree) substantially; Facing directly towards the upper reaches, river of triangular prism (2), the inclined-plane is dirty towards the river, and facing directly with riverbank (1) of triangular prism (2) becomes 90 basically
0The angle.Triangular prism (2) enters the river bed in the river part from the river surface straight cutting, can insert under the river bed 0.2-1.00 meters again; In the riverbank part, triangular prism (2) inserts the same degree of depth too.
Triangular prism (2) can be used stone, and also available steel concrete is built; During the steel concrete pouring construction, at first dig out deep trouth, the following and side of deep trouth keeps apart with sheet material (plank, plastic plate etc.), forms the space, and the reinforcing bar of weaving in the space again is poured into concrete at last.Triangular prism (2) can be all equally large up and down, also can be big end down, as shown in Figure 3.
Embodiment 2: 5～7 this embodiment is described by reference to the accompanying drawings.(1) inserts several trapezoidal column (5) on the riverbank, trapezoidal column (5), and large one towards the riverbank, and little one towards the river, as shown in Figure 7.Trapezoidal column (5) in the river part, enters the river bed from the river surface straight cutting, can insert under the river bed 0.2-1.00 meters again; In the riverbank part, insert too the same degree of depth.
Trapezoidal column (5) can be used stone, and also available steel concrete is built; During the steel concrete pouring construction, at first dig out deep trouth, the following and side of deep trouth keeps apart with sheet material (plank, plastic plate etc.), forms the space, and the reinforcing bar of weaving in the space again is poured into concrete at last.Trapezoidal column (2) can be all equally large up and down, also can be big end down, as shown in Figure 6.
