Embodiment Construction

[0030] Referring to accompanying drawing, waste tire overflow dam, the riverbed 15 is provided with the retaining dam that waste rubber tire 1 masonry forms, the middle of retaining dam is overflow dam section 2, and both ends are non-overflow dam section 3, overflow dam section The elevation of the overflow surface 4 of 2 is lower than that of the dam top surface 5 of the non-overflow dam section 3. A slab bridge 9 is erected above the overflow dam section 2, and a pier 10 is supported under the slab bridge 9. The downstream slope foot of the overflow dam section 2 An apron 11 is arranged on the riverbed 15 at the place; an upstream slope protection 21, a front dam shell 22, a front reverse filter layer 23, an anti-seepage body 24, and a rear Reverse filter layer 25, rear dam shell 26, downstream slope protection 27, anti-seepage body 24 is located above the water intercepting groove 20 at the position of the dam axis, the cross section of the overflow dam section 2 is trapezo...

Abstract

The invention discloses an overflow dam for waste tires. In the overflow dam, a riverbed is provided with a water retaining dam which is formed by building waste rubber tires; an overflow dam section is formed in the middle of the water retaining dam; non-overflow dam sections are formed at the two ends of the water retaining dam; the altitude of the overflow surface of the overflow dam section is lower than the dam top surface of each non-overflow section; a plate type bridge is erected above the overflow dam section; the riverbed at the downstream slope toe of the overflow dam section is provided with an apron; an upstream protection slope, a front dam shell, a front inverted filter, a seepage-proof body, a rear inverted filter, a rear dam shell and a downstream protection slope are arranged in sequence in the water retaining dam ranging from an upstream dam slope to a downstream dam slope; and the seepage-proof body is positioned above a cutoff trench on the axis of the dam. Due tothe adoption of the overflow dam for waste tires, a dam body has the advantages of simple structure, reasonable stress, high shock resistance, scour prevention, high adaptability, small work amount, convenience for construction, no pollution to water sources, long service life, waste recovery and low cost, and is a novel farmland water conservancy pond dam building; and the problem that a soil-stone dam cannot overflow is solved.

Description

[0001] technical field [0002] The invention relates to the field of hydraulic structures built with waste automobile tires, in particular to waste rubber tire overflow dams. [0003] technical background [0004] At present, the materials used to build overflow dams are usually cement concrete, stone masonry, and rockfill. Due to the considerable amount of dam-building materials, the project cost is relatively high. For example, sand and gravel in the river channel near the dam site are used as dam building materials, and an earth-rock dam with rocks for slope protection can reduce the project cost, but the dam crest cannot overflow, otherwise it will cause dam failure. [0005] Contents of the invention [0006] The purpose of the present invention is to provide a waste rubber tire overflow dam, which uses the characteristics of waste automobile tires such as low cost, large quantity, light weight, large contact area under force, and erosion resistance, etc., as the ...
