The invention discloses a construction method of a shallow tunnel in a Xigeda special stratum. The construction method of the shallow tunnel in the Xigeda special stratum comprises the following stepsthat 1, advance geological forecast is carried out; 2, an improved small-and-medium-sized excavator is used for bench cut method excavation assisted by manual operation; 3, a small guide pipe and a large pipe shed with built-in bundled bars are adopted to carry out advanced support; 4, the initial support stiffness is increased, water guiding and drainage treatment is carried out, and then concrete wet spraying is carried out; 5, the deformation stability is analyzed through monitoring and measurement, and if disqualification exists, rectifying is carried out until the deformation stability is qualified; and 6, secondary lining is carried out, the safe step distance is strictly controlled, and timely closing is carried out to form a ring. The construction method of the shallow tunnel in the Xigeda special stratum starts from various links such as excavation, initial support, water guiding and drainage, safe, fast, efficient and low-cost tunnel construction is realized, and the construction method of the shallow tunnel in the Xigeda special stratum is especially for construction of the shallow tunnel in the Xigeda special stratum.
