When the device is used for paving the honeycomb grid subgrade, a worker firstly turns over the turnover plate 2 upwards, places the honeycomb grid on the base plate 3, inserts holes on the grid into the honeycomb grid stretching mechanism 15 by the last grid of the honeycomb grid, then starts the electric push rod 5 to push the pushing plate 4 to gradually push the honeycomb grid to the feeding flashboard 11, the feeding flashboard 11 is positioned at a position for placing the limiting honeycomb grid in an initial state, the discharging flashboard 9 is positioned at a lifting position, the initial position of the limiting teeth of the discharging flashboard 9 is positioned at the rear side of the limiting teeth of the feeding flashboard 11, the distance is the difference between the front and rear directions of two adjacent joints in a folded state of the honeycomb grid, because the grids of the two adjacent rows of the honeycomb grid are staggered, the limiting teeth of the discharging flashboard 9 and the limiting teeth of the feeding flashboard 11 intersect and are staggered so as to limit the honeycomb grid more accurately, when the honeycomb grid is pressed to the feeding gate plate 11 in a contact way, the electric push rod 5 pushes the honeycomb grid to move backwards, the honeycomb grid simultaneously drives the feeding gate plate 11 and the first sliding block 12 to move backwards, the feeding gate plate 11 and the first fixed block 10 slide relatively, the first sliding block 12 and the fixed plate 13 slide relatively, the first spring 14 is stretched simultaneously, when the limit teeth of the feeding gate plate 11 move to the front side of the limit teeth of the discharging gate plate 9 and the distance between the limit teeth and the limit teeth is the difference between the front and rear directions of two adjacent joints in the folded state of the honeycomb grid, the electric push rod 5 stops pushing the honeycomb grid to move backwards, the first cylinder 7 controls the discharging gate plate 9 to move downwards, at the moment, the limit teeth of the discharging gate plate 9 are just inserted into the next row of honeycomb grid to limit the subsequent honeycomb grid, the second cylinder 8 controls the feeding gate plate 11 to lift upwards, and a row of honeycomb grids between the discharging gate plate 9 and the feeding gate plate 11 are released, meanwhile, the feeding gate plate 11 loses the limit of the honeycomb grids, the feeding gate plate 11 is reset due to the tensile force of the first spring 14, the feeding gate plate 11 is lifted up to the highest position by the second air cylinder 8 and then is reset after the feeding gate plate 11 is moved forward, the feeding gate plate 11 is driven to move downwards by the second air cylinder 8, the next row of honeycomb grids of the limiting honeycomb grids of the discharging gate plate 9 at the moment are limited, and then the first row of grids released by workers are fixed.

The vehicle is then started to repeat the above operation to release the honeycomb grids row by row, because of the nature of the honeycomb grids, the distance between the two ends of the honeycomb grids is gradually reduced when the honeycomb grids are stretched, the stretched length of each row of honeycomb grids is inversely proportional to the width of each row of honeycomb grids, in order to adapt to the road surfaces with different widths, the width of the honeycomb grids needs to be controlled by controlling the stretched length of each row of honeycomb grids, the stretching of each row of honeycomb grids with preset value length is performed by controlling the matching of the discharging speed of the discharging gate plate 9, the feeding gate plate 11 and the moving speed of the vehicle body 1 so that the honeycomb grids reach the preset width, and when the honeycomb grids are arranged on the substrate 3, the worker installs the last row of honeycomb grids on the honeycomb grid stretching mechanism 15, so that the whole device can stretch the last row of honeycomb grids to the preset state.

When the multi-row honeycomb grids are released to stretch, the stretching degree of each row of honeycomb grids is different, the width of each row of honeycomb grids is different, the whole honeycomb grids are distributed in a trapezoid shape, the honeycomb grids are made of soft materials, the guiding limiting mechanisms 16 are required to conduct guiding limiting on two sides of the honeycomb grids, meanwhile, when the honeycomb grids are stretched, the grids in the middle of the honeycomb grids are stretched only by pulling force of the front row, the whole stretching process cannot ensure that the pulling force of each grid of the honeycomb grids is the same, the stretching degree of the grids in the middle of the honeycomb grids cannot be guaranteed, limiting and shaping are conducted on the grids of each row of honeycomb grids through the shaping limiting mechanisms 17, soil filling operation is conducted on the grids of each row of honeycomb grids through the soil filling mechanisms 18, and therefore the stretched honeycomb grids are fixed through direct covering soil stones without being fixed independently through other fixing modes.
