Teaching model for construction of earth and rockfill dam

Abstract

The invention discloses a teaching model for construction of an earth and rockfill dam. The earth and rockfill dam has a clay core and is constructed by filling and laminating earth and rockfill layer by layer, clay masonry is substituted by bricks within 60cm of the outline of the earth dam, two sides of the cross section of the earth and rockfill dam are supported by channel steel 6.3, pulled and fixed by round steel phi20 and enclosed by toughened glass with the thickness of 8mm; the earth and rockfill dam comprises an earth and rockfill dam top, a dam body seepage-proofing body, a drainage facility, a protective slope and dam slope drainage facility and a visiting passageway, wherein a standard traffic road is built on the earth and rockfill dam top, border stones and drainage ditchesare arranged on the downstream side of the earth and rockfill dam top; rock mounds and the drainage ditches are arranged at the foot of the earth and rockfill dam to constitute the drainage facility;a dry stone pitching is arranged on the upstream face of the dam body of the earth and rockfill dam, and a turf protective slope provided with concrete meshes is arranged on the downstream slope of the dam body of the earth and rockfill dam; and the visiting passageway is arranged in a laboratory. According to the invention, field teaching and actual practices are combined to make the shortage ofthe work site practice outside schools.

[0002] Water conservancy engineering construction technology is a core course of water conservancy majors in higher vocational colleges (water conservancy and hydropower construction engineering, water conservancy engineering, water conservancy engineering construction technology, water conservancy engineering supervision, urban water conservancy, etc.), and on-site teaching has always been the core of restricting professional talents One of the bottlenecks in the quality of ability training, although, according to the talent training plan, students can be arranged to carry out on-site internships at the construction sites of water conservancy projects, but because most of the projects are located in remote mountainous areas, there are many inconveniences in transportation, board and lodging conditions, etc. In addition, each water conservancy Each project has its own particularity, and the construction period is relatively long. Students can only see the partial construction process and part of the construction technology when they go to the site, and it is difficult to see the comprehensive and overall construction process. It is even more impossible for students to go deep into various positions for practice, which will affect the effect of construction practice
