Embodiment Construction

[0018] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0019] The present invention provides a geocell and fiber blanket slope ecological protection structure, the ecological protection structure includes a geocell 1 laid along the slope and a fiber blanket 2 covering the geocell 1 . The present invention combines the complementary advantages of geocell ecological slope protection technology and fiber blanket ecological slope protection technology to successfully create a semi-closed cell with an upper surface imitating plant litter, which can not only stabilize the thick layer of guest soil but also maintain the surface layer Thick-layer alien soil vegetation protection technology for high and steep rocky slopes without loss of seeds and soil layers.

[0020] Specifically, the geocell includes at least part of fishbone fence-shaped geocell sheets 3, and the connection bet...

Abstract

The invention relates to an earthwork standard room and fiber blanket combined side slope ecological protection method and an earthwork standard room and fiber blanket combined side slope ecological protection structure. By a specially-made earthwork standard room product, complementation of advantages of an earthwork standard room technology and a plant fiber blanket technology and innovation of a combined construction process are implemented; by a honeycomb skeleton formed by the earthwork standard room on a high and steep side slope, a firm foundation of a thick soil replacement layer is implemented; by a nest skeleton formed by a plant fiber blanket on a soil replacement surface layer, plant seed and topsoil loss protection is implemented; by a tip-shaped bulge structure of an outward face of the earthwork standard room, rigid contact with the fiber blanket is weakened, so that a gap between the fiber blanket and topsoil is partially eliminated; meanwhile, tip-shaped bulges are inserted through the fiber blanket, so that combination of the fiber blanket and the earthwork standard room can be implemented and downhill diastrophism slippage is prevented.

Description

technical field [0001] The invention relates to a side slope ecological protection structure, in particular to a side slope ecological protection method and structure in which geocells and fiber blankets are combined. Background technique [0002] The geocell is a grid cell structure formed by high-strength HDPE or PP copolymer wide band, which is welded or riveted by strong force. It can expand and contract freely, and can be collapsed during transportation. When used, it is opened and filled with earth, stone or concrete materials to form a structure with strong lateral restrictions and high rigidity. It can be used as a cushion to deal with weak foundations and increase the bearing capacity of the foundations. It can also be laid on slopes to form slope protection structures, and it can also be used to build retaining structures. [0003] At present, when ordinary geocells are used for ecological protection of high and steep slopes, although the lateral restraint force o...
