Detailed Description
The technical solutions in the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the application discloses a slag dam for soil and water conservation. Referring to fig. 1 and 2, a dam for retaining soil and water includes a dam body 11, and the dam body 11 is formed by casting concrete. The dam body 11 is provided with water through holes 111, and the water through holes 111 completely penetrate through the dam body 11. The water holes 111 are inclined upward from the water-facing side to the water-backing side of the dam body 11. When water flow passes through the water through holes 111, waste slag contained in the water flow is easy to settle on the bottom surfaces of the water through holes 111 due to the self gravity, so that the waste slag is not easy to enter the backwater side of the dam body 11 through the water through holes 111, and the waste slag is better blocked.
Referring to fig. 1 and 2, a filter plate 112 is disposed on the upstream surface of the dam 11, the top end of the filter plate 112 is hinged to the dam 11, and the filter plate 112 naturally falls and is fastened to the water inlet end of the water through hole 111 under the action of its own gravity. The big waste slag in the water flow can not enter the water through holes 111 under the blocking of the filter plates 112, so that the water passing is smoother, and the blockage of the water through holes 111 caused by the big waste slag is greatly reduced. The filter plate 112 is hinged, so that when the water through hole 111 is cleaned, the filter plate 112 can be turned upwards, and waste slag in the water through hole 111 can be flushed out conveniently.
Referring to fig. 3, in order to prevent the filter plate 112 from being lifted up by the impact of the water flow, sleeves 1121 are fixedly disposed on both sides of the filter plate 112, and lock posts 1122 are sleeved in the sleeves 1121. And positioning pipes 1123 are fixedly arranged on the dam body 11 at two sides of the water through hole 111, and the positioning pipes 1123 are positioned on the upstream surface of the dam body 11. When the filter sheet 112 covers the water through hole 111, the axes of the sleeve 1121 and the positioning tube 1123 coincide with each other, so that the lock cylinder 1122 can be inserted into the positioning tube 1123, and the filter sheet 112 cannot rotate.
Referring to fig. 1 and 2, in order to prevent the filter plates 112 from being clogged by the waste slag, the filter plates 112 are formed in a hemispherical shape and protrude in a direction away from the dam body 11, so that the waste slag is not easily accumulated on the filter plates 112. The waste slag is stopped by the filter plate 112 and falls down under the action of gravity, thereby effectively reducing the amount of the waste slag stopped on the filter plate 112.
Referring to fig. 1 and 2, in order to collect the waste slag, a slag collecting groove 12 is fixedly arranged at the bottom end of the dam body 11. Wherein, the slag collecting groove 12 is positioned on the water facing side of the dam body 11. When the waste slag falls naturally due to the blockage of the dam body 11, the waste slag can fall into the slag collecting groove 12, and the effect of uniform collection of the waste slag is achieved, so that the waste slag is not prone to scattering around under the impact of water flow, and the cleaning difficulty is reduced.
Referring to fig. 1 and 2, a drainage hole 121 is formed in the slag collection groove 12, so that when the waste slag in the slag collection groove 12 is cleaned, water can be drained from the slag collection groove 12 through the drainage hole 121, thereby reducing the difficulty in cleaning the waste slag.
Referring to fig. 1 and 4, a slag blocking cover 113 is fixedly arranged on the dam 11, and the slag blocking cover 113 is positioned on the backwater side of the dam 11 and covers the water through holes 111. Wherein, the top end of the slag bridge 113 is provided with an opening, so that water can flow out from the top end of the slag bridge 113 after flowing out from the water through hole 111. The slag trap shroud 113 further provides a barrier to the disposal of the slag contained in the water stream. After the waste slag is flushed out of the water through holes 111 by the water flow, the waste slag is blocked by the slag blocking cover 113, so that the waste slag cannot fall out of the water through holes 111.
Further, referring to fig. 1 and 4, in order to improve the firmness of the slag blocking cover 113 on the dam 11, a reinforcing rib 114 is fixedly arranged between the dam 11 and the slag blocking cover 113. The reinforcing rib 114 is in the shape of a right triangle, one right-angle side of the reinforcing rib 114 is fixedly connected with the slag blocking cover 113, and the other right-angle side of the reinforcing rib 114 is fixedly connected with the dam body 11. The reinforcing ribs 114 can improve the impact resistance of the slag blocking cover 113, so that the slag blocking cover 113 is more stable on the dam body 11, and the service life of the slag blocking cover 113 is prolonged.
Referring to fig. 2 and 4, a slag barrier 13 is fixed to the top of the dam 11 to block the waste floating on the water. When the water surface passes over the dam body 11, the slag blocking guardrail 13 can enable the water flow to normally pass through, only blocks the waste on the water surface, and enables the waste not to enter the downstream water area.
Referring to fig. 1, in order to improve the stability of the overall structure of the dam 11, the cross section of the dam 11 is trapezoidal, that is, the structure has a narrow upper end and a wide lower end, so as to slow down the impact of water flow on the dam 11 and prolong the service life of the dam 11.
The implementation principle of the embodiment of the application is as follows: the waste slag carried in the water flow is blocked by the dam 11 and cannot enter the downstream water area. The water flows through the strainer plate 112 into the water through holes 111, and the large waste residues carried in the water flow are blocked by the strainer plate 112 from entering the water through holes 111. When the water flow flows along the water through holes 111, the small waste slag contained in the water flow can be settled on the inner wall of the water through holes 111. Part of the small waste slag is washed out from the water through holes 111 under the washing action of water flow, and the small waste slag can not enter the downstream water area under the blocking action of the slag blocking cover 113.
When the waste slag is cleaned, the water flow flowing upwards is cut off, so that the water flow does not flow through the dam body 11 any more. The strainer plate 112 is turned up so that the water inlet end of the water through hole 111 is completely exposed. Water flow is poured into the slag blocking cover 113, and when the water flow flows through the water through holes 111, the waste slag in the water through holes 111 can be flushed out, and the waste slag can fall into the slag collecting groove 12.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
