Anti-scouring and anti-sliding structure and its construction method for the road slope opposite the outlet of the diversion tunnel

Abstract

The invention discloses an anti-scouring and anti-sliding structure and a construction method for the road slope opposite the outlet of a diversion tunnel, belonging to the field of water conservancy and hydropower engineering, and provides a short construction period, convenient construction and low investment suitable for diversion tunnels The anti-scouring and anti-sliding structure and construction method of the road slope on the opposite bank of the exit, the anti-scouring and anti-sliding structure of the road slope on the opposite bank at the exit of the diversion tunnel, specifically includes the slope body, and a traffic road is arranged on the upper part of the slope body. Including concrete cogged foundation, concrete cogged superstructure, lump cinder fill structure and reinforced concrete slope protection. The present invention can form the first construction access road as a construction platform by means of the rapidly built lump slag filling structure itself, which can greatly speed up the construction progress and shorten the construction period; The upper structure of the alveolar can reinforce the better foot protection, greatly improving the stability and anti-shock effect of the overall structure.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to an anti-scouring and anti-sliding structure and a construction method for the road slope opposite the outlet of a diversion tunnel. Background technique [0002] At present, many water conservancy and hydropower projects are being built, planned and designed in the southwest region of China, such as Shuangjiangkou, Lianghekou, Rumei, Changheba, Marban, Yebatan, etc. These water conservancy and hydropower projects are located in high mountains and canyons, with steep slopes on both sides of the river bed. The construction diversion adopts the tunnel diversion scheme of excavating corresponding diversion tunnels in the mountains. However, the water flow velocity at the outlet of the diversion tunnel of a hydropower project is extremely high, and the opposite bank of the outlet is mostly a road slope with a deep cover layer, and the road slope is often dam...

Problems solved by technology

The document with the patent number 201610605908.4 discloses a "slope anti-scour and anti-skid structure", which includes an underground diaphragm wall structure, but its construction process is complicated, the investment is high, and the construction period is long, so it is difficult to apply to the slope of the road opposite the diversion tunnel exit.
