Embodiment Construction

[0045] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0046] Such as Figure 1 to Figure 2 As shown, a geobag embankment reinforcement method, the reinforced embankment has both the functions of embankment and riverside landscape road. The original embankment 1 in the figure is an earth embankment with a gentle slope and narrow embankment crest width, which has hidden dangers of seepage and sliding damage. Geotechnical bag technology is used to reinforce the backwater side of the dam. The preferred size of geotechnical bag 3 is 100cm*100cm*30cm. The dyke is excavated in three stages. The outer contour does not exceed the toe line 4 of the original embankment slope, so as to ensure that the embankment can be reinforced without occupying the land. The asphalt pavement 5 laid on the top of the dam inc...

Abstract

The invention discloses a geotextile bag dam reinforcing method. Geotextile bags are adopted to reinforce the downstream side of a dam along a river, the dam top is widened under the condition that noland is occupied, a pavement is paved on the widened dam top to serve as a riverside landscape road, the method has the principle that the anti-sliding and anti-seepage stability and the vertical bearing capacity of the dam are improved through the interlayer friction and embedding and fixing effects of the geotextile bags, the water filtration and soil conservation effects of the geotextile bagsand the additional cohesive force provided by the geotextile bags to internal soil. Therefore the method not only can improve the stability of the dam under the condition of not occupying the land, but also increases the application of the dam as a riverside road. The filling material in the geotextile bags can adopt on-site excavated spoil or nearby urban muck and the like, so that waste is changed into treasure, and the waste becomes a renewable resource.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a geotechnical bag embankment reinforcement method. [0002] Background technique: [0003] Embankment works refer to water-retaining structures built along the edge of rivers, canals, lakes, coasts or flood areas, flood diversion areas, and reclamation areas. According to construction materials, it can be divided into: earth embankment, stone embankment, earth-rock embankment and concrete flood wall. Most of the embankments in the world are earthen embankments, which are built with local materials and have simple structures, mostly trapezoidal cross-sections. [0004] For many years, the problem of embankment reinforcement has always been an important link in the construction of water conservancy projects. With the rapid increase of China's urbanization rate and the rapid development of the rural economy, urban flood control standards are also gradually increasing. Many existin...
