A kind of mountain torrent debris flow sand retaining dam with power generation function and its application

Abstract

The invention relates to the field of geotechnical engineering for geographical environment control, and specifically discloses a torrent and debris flow sand retaining dam with the function of generating electricity and its application. In the present invention, by adding a splitter device upstream of the sand control dam, the turbine water filter net and the debris flow grid in the device can filter and separate water and stones, and can use the separated water for water storage, and use the height difference to make the sand control dam It has the function of generating electricity. The torrent and mud-rock flow sand retaining dam of the present invention not only reduces the disaster of torrent and mud-rock flow, but also utilizes the advantage of the natural height difference of the sand retaining dam to generate power, so that the sand retaining dam has certain economic utility.

Description

technical field [0001] The invention relates to the field of geotechnical engineering for geographical environment control, in particular to a torrent and debris flow sand retaining dam with power generation function and its application. Background technique [0002] Mountain torrents and mudslides are extremely destructive natural disasters, which are very common in mountainous areas of our country and bring great resistance to the development and construction of infrastructure in the west of the country. As a typical debris flow protection engineering structure, sand check dam has multiple functions such as reducing ditch bottom erosion, intercepting flow, separating water and rock, and reducing fluid kinetic energy, so it has been widely used. [0003] Patent CN102182163B discloses an assembled debris flow sand retaining dam and its construction method. The sand control dam includes several prefabricated reinforced concrete rectangular boxes connected vertically and hori...

AI Technical Summary

Problems solved by technology

The invention makes full use of the fast assembly characteristics of the rectangular box, and the rectangular box can be pre-prepared at a site far away from the sand dam, and can be carried out simultaneously with the construction of the foundation of the sand dam, which can not only shorten the construction period, but also reduce the Small impact on the surrounding environment of the sand control dam site; the existing soil in the ditch can be directly filled with the rectangular box, thereby solving the problem of mass transportation of construction materials; compared with traditional sand control dams, it can save engineering investment by 20-50% , saving 20-80% of the construction period, but it fails to separate the water and stones in the debris flow well, and has no other economic use
