Problems solved by technology

[0002] The design of drainage channels in mountainous and hilly areas, such as the height of channel side walls, needs to consider the hydraulic characteristics of steep slope rapids. In the prior art, the height of steep channel side walls is usually set to the sum of clear water depth, aerated water depth and safety superelevation , the steep channel margin obtained by this calculation method is too large. At the same time, the height of the side wall of the steep channel designed in the prior art is not designed according to the position of the aeration point. The height of the side wall of the steep channel before and after the aeration point is They are all the same, wasting building materials and increasing the manufacturing cost of the project

Embodiment 1

[0063] This embodiment discloses a calculation method for the height of the side wall of a steep slope channel. The side wall of a steep slope channel is as follows: figure 1 and figure 2 As shown, the calculation method includes the following steps:

[0064] Step 1: Calculate the clear water depth h in the steep channel 0 .

[0065] Among them, the calculation of the clear water depth h in the steep slope channel 0 Specifically include:

[0066] Calculate the clear water depth h by the following formula 0 :

[0067] W 0 =(B+mh 0 )h 0 (1)

[0068] In equation (1), W 0 is the water passing area of ​​the section of the steep channel, B is the bottom width of the section of the steep channel, and m is the slope gradient of the section of the steep channel.

[0069] In the present embodiment, the bottom width B of the section of the steep slope channel and the side slope gradient m of the section of the steep slope channel are obtained according to the measurement of ...

Embodiment 2

[0102] This embodiment provides a calculation device for the height of the side wall of a steep slope channel. The calculation device adopts the calculation method for the height of the side wall of the steep channel channel in Embodiment 1 to calculate the height of the side wall. Specifically, it includes a first calculation module, a second A calculation module and a determination module, wherein the first calculation module is used to calculate the clear water depth h in the steep slope channel 0 , the second calculation module is electrically connected to the first calculation module, and is used to calculate the aerated water depth h in the steep slope channel a , the determination module is electrically connected to the first calculation module and the second calculation module respectively, and is used to determine the position of the aeration point and the depth of clear water h 0 and aerated water depth h a Determine the height h of the side wall.

Abstract

The invention discloses a method for calculating the height of a side wall of an abrupt slope channel. The method comprises the following steps: calculating the water depth h0 of clear water in the abrupt slope channel; calculating the aerated water depth ha in the abrupt slope channel; and determining the height h of the side wall according to the position of the aeration point, the clear water depth h0 and the aeration water depth ha. The invention further discloses a device for calculating the height of the side wall of the abrupt slope channel. The side wall height of the abrupt slope channel obtained through the method for calculating the side wall height of the abrupt slope channel is more reasonable, and materials of the drainage channel side wall can be saved.

Description

technical field [0001] The invention specifically relates to a calculation method and a calculation device for the height of the side wall of a steep slope channel. Background technique [0002] The design of drainage channels in mountainous and hilly areas, such as the height of channel side walls, needs to consider the hydraulic characteristics of steep slope rapids. In the prior art, the height of steep channel side walls is usually set to the sum of clear water depth, aerated water depth and safety superelevation , the steep channel margin obtained by this calculation method is too large. At the same time, the height of the steep channel side wall designed in the prior art is not designed according to the position of the aeration point. The height of the steep channel side wall before and after the aeration point is All the same, waste building materials, increase the manufacturing cost of engineering. Contents of the invention [0003] The technical problem to be sol...
