Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 As shown, the water tower used for river discharge of the present invention includes a tower body 2, and the tower body 2 is provided with a water inlet, and the number of water inlets can be 1, 2 or other quantities, figure 1 In the center, two water inlets are provided, namely the water inlet 22 and the water inlet 24, and the tower body 2 is also provided with a discharge outlet 27, which is used to change the flow direction of the water flow in the river channel and then flow into the tower body through the water inlet. Inner tower body water blocking wall 23.

[0027] When used, such as figure 1 with figure 2 As shown, the above-mentioned water tower can be set in the river channel 3, and the outlet 27 of the tower body is connected with the entrance of the drainage channel 1, so that the water flow in the river...

Abstract

The invention discloses a water column for river drainage and a drainage method, which are beneficial to guaranteeing long-term smoothness of a drainage channel. The water column mainly comprises a column body provided with a water inlet and a water outlet, and a column water retaining wall for changing flow direction of water in the river and leading the water to flow from the water inlet into the column body is disposed on the column body. An internal water stop structure is further disposed inside the column body. The drainage method mainly includes: installing the water column in the river; communicating the water outlet of the column body with an inlet of the drainage channel; reserving the water inlet of the column body to be between the column water retaining wall and the water outlet of the column body, and using the column water retaining wall to change the flow direction of the water, flowing towards the drainage channel, in the river, so that the water is led to flow from the water inlet of the column body into the column body and flow from the water outlet of the column body into the drainage channel.

Description

technical field [0001] The invention relates to a river channel discharge water tower used in mud-rock flow or multi-movement channel, and also relates to a discharge method of the river channel. Background technique [0002] When diverting water from mudslides or multi-moving rivers, a large amount of sand and stone will enter the drainage channel, causing the drainage channel to be worn and damaged, requiring frequent maintenance of the drainage channel, resulting in high maintenance costs for the drainage channel. And after the debris flow erupts, it may also block the drainage channel. After the drainage channel is blocked, the mud-rock flow will be diverted, and the diversion of the mud-rock flow will cause great disaster. Similar damage and disasters abound in mountainous areas where mudslides are frequent and there are many moving rivers. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a water tower for river ch...
