The shape of the slot 7 and the protruding block 6 only needs to be matched with each other, in this embodiment, the protruding block 6 is set to be L-shaped, and then the slot 7 is also L-shaped. The bulge block 6 is inserted into the slot 7 to fix the internal layered structure, so that the internal layered distribution is orderly and not loose.
Example two:
the present embodiment provides a method for laying a movable vegetation greening blanket on a side slope, where the greening blanket adopts the structure of the first embodiment, and on a slope of a sandy wasteland, such as a sandy wasteland beside a yellow-economic green desilting basin, the sandy wasteland is very easy to be eroded by wind due to the fine silt of a yellow river, and the sandy wasteland is often changed due to dredging and utilization of the sandy desilting basin. At the slope surface of the barren sand land, the construction slope surface needs to be cleaned firstly, large pumice and sundries are removed, and the flatness of the construction surface is kept. And measuring the construction surface and calculating the number of the needed unit structures. And (4) transporting the required structural material to a construction site, and paving the required structural material on the top of the smooth construction soil slope from the top of the soil slope to the downstream in sequence.
For the barren sand land with a certain height (for example, 6m), a manual laying method can be used on the slope surface of the barren sand land, two traditional bamboo ladders are used simultaneously, each person stands on one bamboo ladder, the two bamboo ladders are manually assisted to finish the laying, and the unit structures are laid at the position of the toe of the slope from the upward slope in a row. Can be used together with a movable sand-fixing unit and a sand-fixing method utility model patent (application number: 201910625486.0).
On the barren sand ground beside the sand basin, when a first row of greening blanket unit structures are laid at the top of the soil slope, the convex blocks 6 of the grid covering layer 4 are buckled into the slots 5, the unit structures at the rear row are sequentially laid and buckled into the slots 5 at the upper row, and meanwhile, the slots 5 of the grid layer 1 are inlaid into the soil slope, so that the stability of the greening blanket is ensured. At the slope toe, a wood pile is driven into the slot 5 of the last unit structure for fixation, so that the integral structure of the vegetation blanket is ensured to be stably leaned against the top of the soil slope, and the vegetation blanket is prevented from sliding off.
For the barren sand land with the height of more than 6m, the method needs to be paved by matching with a conveying mechanism and comprises the following steps:
(1) installing a transmission mechanism between the top of a slope and the foot of the slope in the wasteland:
the conveying mechanism comprises two groups of rollers 7 driven by a motor, and each group of rollers 7 is connected through a steel wire 8. When the conveying mechanism is installed, the rollers 7 at the top of the slope and the bottom of the slope are kept on the same vertical surface, the two rollers 7 are connected by steel wires 8, and the steel wires of medium and thick grades are adopted in the implementation.
The distance between the rollers 7 positioned at the top of the slope in the two groups of rollers 7 is consistent with the distance between the two rollers 7 at the bottom of the slope, and the connecting line between the two rollers 7 at the top of the slope is ensured to be parallel to the connecting line between the two rollers 7 at the bottom of the slope. The steel wire between the slope top roller 7 and the slope foot roller 7 needs to be straightened to ensure tight connection, and is prevented from being bent by a greening blanket in the transportation process. In the transportation process, the speeds of the two rollers 7 on the top of the slope are set to be the same, so that the two steel wires can be ensured to move synchronously.
(2) Starting a motor, and placing a plurality of unit structures on the two steel wires 8 one by one, wherein the unit structures are placed without gaps; in order to avoid the unit structures from sliding off during transportation, each unit structure is placed, and barriers are arranged on the lower side of the unit structure, for example, clamps are respectively clamped on two steel wires on the lower side of the unit structure. And when the first unit structure is transported to the top of the slope, the motor is turned off, and the steel wire is fully distributed with the unit structures.
(3) The unit structures on the steel wires are moved down, and after the unit structures are moved down, the obstacles arranged on the steel wires are taken down, so that the unit structures can be conveniently used for transporting the next row of unit structures; the convex blocks 6 and the slots 5 of the adjacent unit structures are clamped together in the sequence from the top of the slope to the bottom of the slope.
(3) After the unit structures are laid, the wood piles are driven into the slots 5 of the last unit structure of the slope toe for fixing, so that the vegetation blanket is guaranteed to stably lean against the soil slope in the whole structure and is prevented from sliding off.
(4) And (5) moving the conveying mechanism to the adjacent row mounting position, repeating the steps (2) to (4) and laying the unit structures row by row.
