Embodiment Construction
[0025] Such as figure 1 As shown, a slope protection structure is provided with a steel structure slag-retaining curtain wall 2, a slag-retaining ridge 3 and a flexible protective net 4 from top to bottom on the slope 1.
[0026] The steel structure slag-retaining curtain wall 2 is set on the slope at a distance of 1-2m from the outside of the excavation sideline, preferably at a distance of 1m; the height of the steel-structure slag-retaining curtain wall 2 is preferably 6m. .
[0027] The slag retaining ridge 3 is a slag retaining ridge arranged on the slope 1.5-3m below the steel structure slag retaining curtain wall 2 by means of drilling and inserting ribs. The preferred distance is 2m, and the height of the slag retaining ridge 3 is preferably 1m.
[0028] The flexible protective net 4 is arranged on the side slope at a distance of 12-18 m from the steel structure slag retaining curtain wall 2, preferably at a distance of 15 m, and the height of the flexible protective ...

The invention discloses a slope protection structure; and a steel structure slag stop curtain wall, a slag stop bank and a flexible protection net are arranged on a slope from top to bottom. A construction method of the slope protection structure comprises the following steps: (1) construction of the steel structure slag stop curtain wall: the steel structure slag stop curtain wall is supported and fixed on a slope surface at a position far from the outer side of a digging edge line by 1-2 m in a manner of inner side traction, outer side ejection and ground anchor anchoring; (2) construction of the slag stop bank: the slag stop bank is arranged on the slope at a position far from the lower side of the steel structure slag stop curtain wall by 1.5-3 m in a manner of drilling and rib insertion; and (3) construction of the flexible protection net: the flexible protection net is arranged on the slope at a position far from the lower side of the steel structure slag stop curtain wall by 12-18 m. The slope protection structure and the construction method thereof, provided by the invention, can solve the problems of high protection construction difficulty and difficult safety and ecological environment protection caused by a lot of slope surface stone rolling and pressing coverage phenomena in the slope excavation construction, and realize the safety and the ecological protection in the slope excavation.
Description
technical field [0001] The invention relates to the field of safety and ecological protection treatment in earthwork excavation construction of engineering slopes such as highways and hydropower stations, in particular to a slope protection structure and a construction method thereof. Background technique [0002] In the construction of slope excavation, there is usually the phenomenon of cross-operation between the upper and lower construction surfaces and the requirement to ensure the safe passage of the road below the construction site, and it is very easy to cause pressure and coverage problems on the slope below the excavated slope, construction safety and ecological environment. Protection problems are prominent, especially in deep-cut alpine and canyon areas, where slopes are steep, and practical and reliable safety and ecological protection measures are necessary conditions for the smooth progress of slope excavation projects.
