Description

Yellow water clarification check gate and method for clarifying river water and maintaining water and soil

Technical Field

The invention relates to a water and soil treatment technology, and belongs to the technical field of water and soil treatment.

Background

The water and soil loss of the current flowing areas of many rivers is serious, for example, the water of yellow river is originally clear water rather than yellow water, and the silt cannot be kept firmly due to the fact that a plurality of trees and vegetations of loess plateau are artificially and infinitely felled and reclaimed for planting fields for thousands of years. The surge is carried away by rainwater flush surge in flood season, and yellow water with 92% of total silt content in yellow river water flows into the yellow river from two midstream of the yellow river every year. Therefore, in order to radically treat the yellow water in the yellow river, all the numerous gullies and main branches must be treated into clear water, so that the major problem that the yellow water in the yellow river cannot be changed into clear water can be thoroughly solved.

In nearly thousands of years, the yellow water treatment of the yellow river is one generation after one generation, the effect is still little till now, and nearly two billion tons of silt flow into the yellow river every year. The reason for the rectification is that the water in the yellow river can never be changed into clear water because many ravines on the loess plateau are not treated or the treatment method is not right.

Many rivers similar to the yellow river basin, such as Yangtze river, Songhua river, peony river … …, etc., all or in part suffer from the above problems.

The working principle of the invention is that taking yellow river as an example:

it can be summarized as a song formula:

the provinces are respectively controlled, and the gullies are changed into reservoir areas.

Moving water to still water, and clarifying the water with yellow water.

The switch gate is on and off, and the clear water is discharged from the warehouse enclosure.

The gully yellow water clarification check gate not only can sink sand in reservoir water, but also can enable the depth of main tributaries and a plurality of gullies to become a perennial reservoir water sand sinking area in a space about 50% of the same horizontal line, and can basically cultivate fish, irrigate farmlands and plant trees after a large amount of sand is settled. And can thoroughly solve the major problems of waterlogging caused by rain, no rain, drought and no water irrigation of farmlands for hundreds of years.

When the rainwater is too large, under the combined action of the reservoir water sand-settling baffle and the check gate, the depth of yellow water flowing into a plurality of large and small gullies in the loess plateau can be gradually increased, and the moving water is changed into static water and yellow water for clarifying the water. When rainwater needs to be discharged, all gates are opened, main branches can flow in orderly, and a large amount of clear water flows into the yellow river again under the control of the main branch check gate.

The method for determining the construction position of the check gate comprises the following steps:

through surveying, measuring, researching, planning and treating, a diagram for trimming, blocking and changing the roads of the gullies in the loess plateau is drawn. In order to facilitate annual irrigation of farmlands and ensure the conservation of sweat waterlogging, a large reservoir is planned to be reserved at any position, large gullies which are vertically and horizontally communicated with the reservoir are reserved, and a reservoir water sand deposition clarification check gate is built at the junction of the gullies and main branches.

In the region with large gully yellow water fall, in order to facilitate sand deposition to make fields, a gully reservoir water sand deposition clarification control gate is constructed at the position of the yellow water fall.

When the farmland is dry and rainy, the large gullies which are communicated with the reservoir vertically and horizontally can guide the water in the reservoir to irrigate the farmland for sweat resistance and harvest preservation. During flood season, under the action of the sediment settling clarification check gates of various reservoirs, the moving water flowing into a plurality of gullies can be changed into still water, after sediment is settled, the yellow water is changed into clear water, the clear water sequentially flows into the main branch flows through the control of the check gates, and flows into the yellow river from the branch flows and the water of the yellow river is changed into clear water.

Planning and renovating gully

And (4) orderly planning and renovating large gullies at two sides of each main branch according to the annual maximum rainwater quantity. The rainwater can flow into the large gullies orderly, and the yellow water can only flow into the large gullies and cannot flow into the branch or the yellow river without authorization. The bridge above the gully yellow water clarification check gate is designed for the traffic of both sides of main tributary and yellow river. After the gate is built, the main branch and the two banks of the yellow river form an ideal road under the action of a plurality of bridges, so that the bridge building cost is saved, and the traffic and the transportation of people are facilitated.

In order to block flood and cut peak in flood season and effectively reduce the downstream flood control pressure, the severe condition that a large amount of flood flows into a yellow river in a short time when a mountain torrent occurs is changed into that: floods can be stocked in large and small ravines or mountain valleys, and can be managed and discharged orderly for a long time. Thereby reducing the rising pressure of the water level, the water flow and the danger degree caused by overhigh water level. The gate can be built at the intersection of the two banks of each river and the port of each large valley.

The technology of the invention can be used in the similar areas of yellow river, Yangtze river, pine pollen, peony river … … and the like.

The above description is only exemplary of the invention and should not be taken as limiting the invention, as any modification, equivalent replacement, or improvement made within the spirit and principle of the invention should be included in the protection scope of the invention.
