9. A glass reinforced plastic grid according to claim 1, wherein: the outer surfaces of the first grid plate (1) and the second grid plate (2) extend back to form a peripheral plate (11), and round holes (111) are formed in the peripheral plate (11).

10. A method of installing a glass fibre reinforced plastic grid suitable for use in any one of claims 1 to 9, wherein: the method comprises the following steps:

s1: cleaning, namely cleaning leaves and other materials at the edge of the tree, paving the stone, paving the soil again, and flattening the soil;

s2: placing, namely placing the first grating plate (1) and the second grating plate (2) in a frame surrounded by the roadbed so that the middle circular holes are sleeved at tree roots after the first grating plate (1) and the second grating plate (2) are spliced;

s3: fixing, namely pushing the second grating plate (2) towards the first grating plate (1), so that the extension block (12) in the second grating plate (2) extends into the top of the connecting plate (3), the extension block (12) impacts the turnover plate (8), the turnover plate (8) is disconnected from the position of the groove (81), the upper part of the turnover plate (8) rotates, the through groove (121) reaches the position of the turnover plate (8), the turnover plate (8) is clamped in the through groove (121) under the elasticity of the torsion spring (7), and the triangular block (33) is clamped in the first extension block (13) under the elasticity of the first spring (34);

s4: and reinforcing, wherein the first cylinder (32) drives the driving plate (4) to extend out of the interior of the first grating plate (1), the second cylinder (41) drives the moving plate (5) to move in the interior of the first grating plate (1), so that the driving plate (4) longitudinally reinforces the first grating plate (1), the moving plate (5) transversely reinforces the first grating plate (1), and then bolts penetrate through the circular hole (111) and the corresponding first circular arc groove (441) and second circular arc groove (511).
