Side slope reinforcing drainage structure and reservoir shore collapse engineering treatment method

Abstract

The invention discloses a side slope reinforcing drainage structure and a reservoir shore collapse engineering treatment method, and relates to the technical field of reservoir shore collapse engineering treatment. The side slope reinforcing drainage structure comprises a reinforced concrete lining with a shear water drainage hole formed in the middle and a drain pipe with a plurality of drainageholes formed in the pipe wall. During reservoir shore collapse engineering treatment, a plurality of layers of side slope reinforcing drainage structures are sequentially arranged from top to bottom in a reservoir hydro-fluctuation belt side slope, one end of the shear water drainage hole extends into the side slope sliding surface, the other end of the shear water drainage hole leads to the outside of the side slope, the shear water drainage hole is slightly inclined downwards towards the outer side of the side slope, and the portion, provided with the drainage holes, of the drain pipe is inserted into a side slope rock soil body. According to the structure, the shear strength of the side slope is remarkably enhanced, the water in the side slope rock soil body can be gathered into the drain pipe through the drainage holes, and is discharged to the shear water drainage hole quickly through the drain pipe, the water collected in the shear water drainage hole can be quickly discharged toa river channel, the transverse and longitudinal water drainage in the side slope rock soil body are taken into consideration through the drainage method, and the water is effectively prevented frombeing retained in the side slope.

Description

technical field [0001] The invention relates to the technical field of reservoir bank collapse engineering treatment, in particular to a slope reinforcement drainage structure and a reservoir bank collapse engineering treatment method. Background technique [0002] After a large reservoir is impounded, the stability of the reservoir bank slope is significantly affected. After the reservoir is impounded, the rock and soil mass that was originally in a naturally dry state will be in a saturated state, which reduces the effective stress of the rock and soil mass on the one hand, and reduces the self-strength of the rock and soil mass on the other hand. In particular, when the water level of the reservoir drops sharply, the water in the rock and soil has no time to drop with the water level of the reservoir, resulting in an increase in the drag force of the rock and soil of the slope in the water-fluctuating zone. At this time, the slope is prone to instability. This is the roo...

Problems solved by technology

These slope treatment measures are more suitable for slopes with insignificant water level changes, but they are not specific for slopes in reservoir drawdown zones

For example, the anti-slide pile reinforcement method commonly used in slope treatment only rigidly resists the sliding force of the slope, and cannot solve the problem of the sliding drag force of the slope water body. When the slope is huge and the seepage pressure of the slope increases, the section of the anti-slide pile often become very large, uneconomical and difficult to construct

In addition, the reinforcement method of anchor cable and bolt support often has the problem of not being able to solve the drag force of the slope water sliding down, and the durability is poor.
