The utility model provides a tunnel drainage system which comprises a first longitudinal drainage unit, a first transverse drainage unit, a second transverse drainage unit and a second longitudinal drainage unit, the first longitudinal drainage unit is used for collecting water coming from a road surface and guiding and draining the water to a roadbed side ditch outside a tunnel, and the first transverse drainage unit is arranged below the road surface. The first transverse drainage unit is arranged below the first transverse drainage unit and used for collecting seepage water at the bottom of a pavement structure and guiding and draining the seepage water to the first longitudinal drainage unit, and the second transverse drainage unit is arranged below the first transverse drainage unit and used for collecting seepage water of surrounding rocks and guiding and draining the seepage water to the second longitudinal drainage unit. The drainage device is used for guiding and draining collected water to a roadbed side ditch outside a hole. Wastewater above the tunnel pavement, seepage water of surrounding rocks and accumulated water at the bottom of the tunnel pavement structure can be smoothly drained out of the tunnel, and meanwhile the construction convenience of the tunnel drainage structure can be considered.

The present invention discloses a self-positioning and rapid assembly molding box for cast-in-place hollow floor slabs, including a cover plate, a side plate and a support. The cover plate includes limit grooves on four sides, evenly distributed exhaust holes and circular holes at four top corners. Adjustment legs can be installed in the circular holes. The length of the adjustment legs is selected according to the distance between the box and the template. The side plates are inserted in the limit grooves of the cover plate to form a rectangular parallelepiped. There are cover plates on the upper and lower side plates. Fixed support seats are injection molded on the cover plate. The support is inserted in the fixed support seat to support the upper and lower cover plates. The present application adopts a structure in which the side plates are inserted in the upper and lower cover plates, which can achieve the effects of rapid disassembly, arbitrary assembly, and arbitrary adjustment of the height of the box.
