A construction method of a miniature slide-resistant pile combined structure for slope ecological protection is characterized by comprising the following steps: the slide-resistant pile combined structure of any one of claims 1 to 8 is used for protecting landslides or side slopes, and the specific construction method is as follows:
surveying the topographic conditions of a landslide or a side slope, and determining the positions, the sizes and the number of the anti-slide pile mounting holes on the slope body (1);
determining the number of corresponding first anti-slide piles (3), second anti-slide piles (5), first connecting rods (6), second connecting rods (7), inclined rods (8), sliding sleeves (9) and supporting rods (10) according to the number of the mounting holes;
thirdly, placing the first anti-slide pile (3) and the second anti-slide pile (5) in the corresponding mounting holes respectively, and pricking the anti-slide piles into the slope body (1) for fixing;
pouring concrete into the mounting hole, and mounting the first connecting rod (6) and the second connecting rod (7) after the concrete is solidified;
fifthly, installing an inclined rod (8) and a sliding-resistant frame (11);
and step six, arranging a proper number of anti-slide pile combined structures according to the size of the side surface of the slope body (1).
