Dam bursting re-blockage construction method based on waste and old tires

Abstract

The invention discloses a construction method for dam breakage and blockage restoration based on waste tires. Heavy blocks; drive positioning piles, so that the positioning piles are inserted into the soil layer with high strength; lap the containment wall, and evenly insert the waste tire counterweights and connecting plates, and finally form the waste tire counterweights and connecting plates alternately distributed 1. Two parallel containment wall structures connected by connecting plates between each row of positioning piles 8; fill in the cut-off material, fill in the cut-off material within the length of a construction unit and compact it; repeat the above process until the dragon mouth closes. The waste tire counterweight in the present invention is simple to manufacture, low in overall price, simple and convenient in construction, fast in construction speed, and meets the urgent needs of flood fighting and emergency rescue. Multiple rows of positioning piles and waste tire counterweights overlap each other to form a containment wall. The overall rigidity is large and the stability is high.

Description

[0001] Technical field: [0002] The invention relates to flood control and reinforcement technology for dams, in particular to a construction method for dam breakage and blocking reconstruction based on waste tires. [0003] Background technique: [0004] During the flood disaster, due to the single filling structure of some embankments, the embankment body is soft under long-term high water level immersion, and the embankment may break under the action of water pressure, which may cause greater disasters. [0005] For example, on June 20, 2010, the Changkai embankment of Fuhe River in Jiangxi Province burst under the action of exceeding the warning water level, forming a 347-meter-long and 4-meter-deep breach, causing large areas of houses to be flooded and nearly 100,000 people forced to leave their homes , causing serious economic losses and social impacts; on August 23, 2013, a breach occurred in the lower reaches of Bacha Township, Tongjiang City, in the east section of t...

[0004] During the flood disaster, due to the single filling structure of some embankments, the embankment body is soft under long-term high water level immersion, and the embankment may break under the action of water pressure, which will cause greater disasters

[0005] For example, on June 20, 2010, the Changkai embankment of Fuhe River in Jiangxi Province burst under the action of exceeding the warning water level, forming a 347-meter-long and 4-meter-deep breach, causing large areas of houses to be flooded and nearly 100,000 people forced to leave their homes , causing serious economic losses and social impacts; on August 23, 2013, a breach occurred in the lower reaches of Bacha Township, Tongjiang City, in the east section of the Tongfu Dam on the main stream of Heilongjiang River, and the width of the breach grew to 420 m, causing more than 3,200 people in 48 villages to be forced to relocate; history Both the Upper Yellow River and the Huaihe River have experienced embankment breaches many times, causing huge loss of life and property
