It can also form drainage channels and water diversion channels, achieving dual functions of protection and drainage, adapting to multiple scenarios and reducing maintenance costs.

The utility model relates to the technical field of slope protection, in particular to a landscape garden ecological slope protection structure which comprises a slope foundation soil layer, a plurality of L-shaped grooves are evenly formed in the top of the slope foundation soil layer, and gravel layers are filled in the L-shaped grooves. According to the slope protection structure, the slope protection mechanism is arranged at the top of the overburden layer, the first pin is inserted into the slope foundation soil layer from the inner bottom face of the L-shaped groove, and the slope foundation soil layer can be stabilized from the top of the slope foundation soil layer by using the laid gravel layer and the supporting mechanism in a matched mode; and one end of a second pin penetrates through a round hole to be inserted into the overburden layer, so that the position of the slope protection mechanism is fixed, the top of the overburden layer is shielded and protected through laid rubber strips and a three-dimensional soil engineering vegetation net, grass seeds on the laid three-dimensional soil engineering vegetation net make contact with the overburden layer, and the overburden layer is protected. And after the grass seeds root and germinate, the slope protection effect on the overburden layer is improved by utilizing the grown grass.

The utility model discloses a port fairway slope protection structure, including the slope protection main part for installing the concrete frame, be equipped with a plurality of ecological bags in the concrete frame, the both sides of concrete frame top are fixed with a plurality of installation buckles through expansion screw, and the opposite two installation buckles between weld have the limit steel wire, and the limit steel wire is contacted with the bottom of ecological bag, be fixedly connected with the connecting buckle on the installation buckle, and the protection grating is clamped to have between a plurality of connecting buckles, and the protection grating is located ecological bag top, the top of concrete frame is equipped with the drainage groove, the bottom of slope protection main part is embedded and is connected with a plurality of gravel cages. The utility model discloses through expansion screw and installs the installation buckle fixedly in the top of concrete frame, and make every limit steel wire be located in the bottom of every column ecological bag, thereby to ecological bag carry out the limit support, and then prevent ecological bag from sliding, improve the slope protection effect.

The invention provides a saline-alkali land drainage ditch plant slope fixing method, which belongs to the technical field of plant slope fixing, and comprises the following steps: S1, constructing ridges and ditches: in spring or autumn, digging ridges and ditches on the slope surface of the drainage ditch, 45-55 cm above the highest water level, and building a ridge every 30-40 m; S2, irrigating and pressurizing salt water: before planting, irrigating and pressurizing salt water into the ridges and ditches; S3, selecting plant varieties: selecting tamarisk and weeping willow as planting seedlings; S4, digging planting holes: when the ridges and ditches are dry and the soil is not too sticky to the shovel, digging planting holes; S5, transplanting: transplanting weeping willows and tamarisks alternately and at intervals into the planting holes dug in step S4; the time interval from seedling removal to planting of tamarisks and weeping willows is ≤3 days; S6, irrigating seedling protection water; irrigating seedling protection water in time after transplanting, and irrigating thoroughly; S7, management and maintenance; the invention adopts the method of planting weeping willows and tamarisks on the slope of the drainage ditch, and using the plant root system to protect the slope of the drainage ditch, and the slope protection effect is remarkable.

The utility model discloses a kind of underwater mould bag laying fixing devices, including mould bag body, the one end of mould bag body is fixedly connected with multiple connection cloth belts, connection cloth belt is cylindrical structure, multiple connection cloth belts are fixedly connected with counterweight bag between, counterweight bag is filled with filling layer, counterweight bag is inserted with central axis, the outer wall of central axis is fixedly connected with multiple through-inserting shafts, another end of through-inserting shaft passes through counterweight bag, the other end of mould bag body is clamped with multiple insertion rings, anchor pile is inserted in insertion ring, one end of through-inserting shaft is conical structure, the one end of mould bag body is equipped with multiple perfusion ports, the top between two described anchor piles is fixedly connected with pedal.
