The invention belongs to the technical field of tunnel engineering construction, and provides a shallow-buried biased segment tunnel stratum reinforcement construction method aiming at solving the problems of potential construction safety danger and the like when a tunnel passes through a high-steep V-shaped gully biased segment with a shallow covering layer. The reinforcement structures comprise a ground line, net sprayed concrete, a reinforced concrete cover plate, a crown beam, slide-resistant piles, steel flora pipes and the tunnel. The whole reinforcement segment is reinforced by the steel flora pipes through grouting; a steel pipe needs to go deep into a tunnel bottom plate for more than 500mm; nets are hung at the ground surface, and concrete is sprayed for construction; the tunnel biased side mainly uses the slide-resistant piles; the slide-resistant piles need to go deep into the tunnel bottom for 5m; in addition, the crown beam is cast on the top of the slide-resistant piles; in addition, the reinforced concrete cover plate with the thickness being 500mm is arranged right above the tunnel and at the slide-resistant pile side; steel bars at a concrete cover plate and net spray concrete connecting part need to be welded together. The construction method effectively solves the problem of shallow-buried biased segment tunnel stratum reinforcement difficulty, and has the advantages that the work procedures are simple; safety and reliable are realized; the water and soil loss is prevented, and the like.
