Geotechnical raft pad for revetment of river lake reservoir and protection method of revetment of river lake reservoir

Abstract

The invention discloses a geotechnical raft pad for a revetment of a river lake reservoir. The geotechnical raft pad comprises a cage-shaped grid network, the grid network is filled with massive stonematerials, the grid network is internally provided with plantation structures at intervals, a filter pad is installed on the lower portion of the grid network, and a vegetation pad is installed on the upper portion of the grid network. The grid network is laid on the revetment of the river lake reservoir, can effectively reduce water and soil loss, and can eliminate waves and prevent waves. The vegetation pad is installed on the upper portion of the grid network, plants can be planted on the vegetation pad, and nutrient substances can be absorbed and water can be filtered to purify water quality by contacting with water through the filter pad. The grid network is filled with the massive stone materials and the plantation structures, a good porous structure can be used for the planting andcutting of various plants, the growth and extension of root systems of plants are facilitated, and the ecological effects of the revetment of the river lake reservoir are quickly realized. The geotechnical raft pad can be manufactured in factory and then hoisted for construction, and compared with a traditional rigid hydraulic structure, construction is fast, and the cost is low. The geotechnicalraft pad is particularly suitable for waterfront soil revetments.

Description

Technical field [0001] The invention relates to the field of ecological protection of the revetment, in particular to a geotechnical raft mat used for the revetment of a river and lake reservoir and a protection method for the revetment of the river and lake reservoir. Background technique [0002] The existing reinforcement structures for the banks of rivers and lakes are mostly hard hydraulic structures (such as stone mortar masonry, gabion gabions, concrete, steel sheet piles, vegetation concrete, etc.). This rigid structure is bulky and heavy Large, aggravated the pressure on the river and lake revetment structure, and the ecological landscape effect is poor, the project cost is high, and the construction period is long. Summary of the invention [0003] In view of the above-mentioned problems, the present invention overcomes at least one shortcoming, and proposes a geotechnical raft mat for the bank of a river and lake reservoir and a protection method for the bank of the riv...

Problems solved by technology

[0002] The reinforcement structures of existing revetments of rivers and lakes are mostly hard hydraulic structures (such as block stone mortar masonry, gabion gabions, concrete, steel sheet piles, vegetation concrete, etc.), such rigid structures are large in size and heavy in weight Large, which increases the structural pressure of river and lake revetments, and the ecological landscape effect is poor, the project cost is high, and the construction period is long
