Background technology
Along with expanding economy, city river water pollution is more and more serious, because a large amount of urban lifes, industrial waste water enter river course, causes river blackout, stench, and oxygen in water is far from enough to meet self-purification of water requirement.In order to improve city river water quality, departments at different levels have taked a series of antifouling reduction of discharging measures in recent years, although played to a certain extent certain effect, effect is also not obvious, and water quality deterioration problem is still very serious.One of effective ways that solve water pollution are to increase oxygen in water, by the self-purification of water, reach the object of improving water quality, adopt artificial oxygenation or drop bank is set under dam more in recent years, utilize drop turbulent fluctuation to reach current aeration reoxygenation effect, these methods have played certain effect to water body purification, but artificial oxygenation consumption wealth consuming time, the common bank oxidation effect that falls is limited, not enough far away to severe contamination stream reaeration amount.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of can mix the dam body of oxygen in sluicing process, and the technical scheme of employing is as follows:
A kind of from the gravity-type oxygen-doped dam body that sluices, comprise dam body body, triangle ventilation bank, rectangle air channel, dam body body bottom surface is plane, and the nearly reservoir side of dam body body is slope, domatic angle is 45 °-60 °, and domatic footing is provided with Concrete Anti erosional layer; Dam body bodies top is plane, width is the 1/6-1/3 of dam body body bottom width, dam body body sluicing upper lateral part is inclined-plane, bevel angle is 45 °-60 °, bottom, inclined-plane for fall " S " domatic, fall that " S " is domatic is provided with equally distributed triangle ventilation bank, form triangle ventilation bank array, triangle ventilation bank drift angle arranges upward, and triangle ventilation bank downside is rectangle air channel, and " S " domatic bottom and the underwater bed that fall is connected smoothly.
Further, triangle ventilation bank is equilateral triangle, and the length of side of rectangle air channel is the 1/6-1/3 of the triangle ventilation bank length of side.
Further, the spacing that adjacent triangle is ventilated between bank is 1-1.5 times of the triangle ventilation bank length of side.
Further, triangle ventilation bank array is 3-6 layer, and adjacent difference in height is between layers 1.5-2 times of the triangle ventilation bank length of side.
Further, the quantity of every layer of ventilation bank of triangle ventilation bank array is equal difference setting from top to down, and difference is 1 or 3.
Further, the relative dam body body of triangle ventilation bank array center line is symmetrical arranged.
Further, the inside of dam body body is the puddle through overcompaction, and top layer is concrete, and concrete thickness is 0.2-0.5 rice.
The beneficial effects of the utility model are that the inclined-plane by dam body body sluicing upper lateral part increased dam water velocity, and then are improved flow turbulence and increased current air entrainment by the triangle bank of ventilating, and then increase content of oxygen dissolved in water, promote water body self-purification ability.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the enlarged diagram of triangle ventilation bank;
In figure: 1 dam body, 2 Concrete Anti erosional layer, 3 puddlies, 4 triangles ventilations banks, the nearly reservoir skew back of 5 dam body body is domatic, 6 dam body bodies top, 7 dam body body sluicing upper lateral part inclined-planes, 8 fall " S " domatic.
The specific embodiment
With reference to Figure of description 1, to 2 pairs, accompanying drawing is of the present utility model, a kind ofly can in sluicing process, mix the dam body of oxygen, be described in detail below.
A kind of from the gravity-type oxygen-doped dam body that sluices as shown in Figure 1, comprise dam body body 1, triangle ventilation bank 4, rectangle air channel, dam body body 1 bottom surface is plane, the inside of dam body body 1 is the puddle 3 through overcompaction, and top layer is concrete, and concrete thickness is 0.2-0.5 rice, the nearly reservoir side 5 of dam body body is slope, domatic angle is 45 °-60 °, and domatic footing is provided with Concrete Anti erosional layer 2, prevents from washing away when reservoir level is lower dam body foundation, dam body bodies top 6 is plane, width is the 1/6-1/3 of dam body body bottom width, dam body body sluicing upper lateral part 7 is inclined-plane, bevel angle is 45 °-60 °, bottom, inclined-plane is for falling " S " domatic 8, fall that " S " is domatic is provided with equally distributed triangle ventilation bank 4, form triangle ventilation bank array, relative dam body body 1 center line of triangle ventilation bank array is symmetrical arranged, triangle ventilation bank 4 drift angles arrange upward as shown in Figure 2, triangle ventilation bank downside is rectangle air channel, triangle ventilation bank 4 is equilateral triangle, the length of side of rectangle air channel is the 1/6-1/3 of triangle ventilation bank 4 length of sides, spacing between adjacent triangle ventilation bank 4 is 1-1.5 times of triangle ventilation bank 4 length of sides, triangle ventilation bank array is 3-6 layer, adjacent difference in height is between layers 1.5-2 times of triangle ventilation bank 4 length of sides, the quantity of every layer of ventilation bank 4 is equal difference setting from top to down, difference is 1 or 3, bottom and the underwater bed of " S " domatic 8 are connected smoothly, protection dam body foundation, cross under dam current and let out in process, first pass through the acceleration on dam body body sluicing upper lateral part inclined-plane 7, then being subject to triangle ventilation bank 4 clashes into, overflow disperses, flow turbulence strengthens, strong turbulence flow entrainments large quantity of air in flow process, the aggravation of current ambient air circulation speed, the free UNICOM of air channel and atmosphere, increase airflow area, can increase air entrainment in water, and then increase dissolved oxygen concentration.
