Waterproof structure at deformation joint of comprehensive pipe gallery and construction method of waterproof structure

The invention discloses a waterproof structure at a deformation joint of a utility tunnel and a construction method thereof, and the waterproof structure at the deformation joint of the utility tunnel comprises a first waterproof structure which is laid at the lower part and the side part of a bottom plate of the utility tunnel; the second waterproof structures are embedded in the comprehensive pipe gallery bottom plates and/or fixed to the outer surfaces of the comprehensive pipe gallery bottom plates, and the second waterproof structures are arranged at the deformation joints of the two adjacent comprehensive pipe gallery bottom plates; and the grouting guide pipe combined waterproof system is buried in the comprehensive pipe gallery bottom plate, and a discharging opening of the grouting guide pipe combined waterproof system is located at the deformation joint or the construction joint. Depending on the self-waterproof characteristic of a concrete structure, the waterproof mode of combining coiled material
