Precast concrete culvert pipe, precast utility tunnel and maintenance method of utility tunnel

Abstract

The invention provides a precast concrete culvert pipe, a precast utility tunnel and a maintenance method of the utility tunnel. Annular end faces at the two ends of the precast concrete culvert pipe are both provided with a waterproof drainage structure. Each waterproof drainage structure comprises a drainage channel (1) and a sealing rubber strip installation groove (2), wherein the sealing rubber strip installation groove (2) is located between the drainage channel (1) and the outer surface of the precast concrete culvert pipe, the distance from the drainage channel (1) to the outer surface of the precast concrete culvert pipe is smaller than that from the drainage channel (1) to the inner surface of the precast concrete culvert pipe. The precast concrete culvert pipe, the precast utility tunnel and the maintenance method of the utility tunnel solve the waterproof problem of a splicing part, the combination of prevention, drainage and plugging is achieved, after the material comes to the end of the service life, the waterproof joints can be further repaired, and the waterproof effect is ensured.

Description

technical field [0001] The invention relates to a prefabricated concrete culvert, a prefabricated comprehensive pipe gallery containing the prefabricated concrete culvert, and a maintenance method for the prefabricated comprehensive pipe gallery.
