The invention provides a construction process of a
precast concrete channel. The construction process comprises the following steps: a, sectioning, namely, according to the
load capacity of a vertical transportation
machine, reasonably sectioning according to the length of a channel, wherein the channel refers to a
reinforced concrete channel; b, channel
processing, namely,
processing and precasting the sectioned channels in a sectioning mode and in a template form, and pre-burying embedded parts on the two sides of the connecting openings of the channels, wherein the connecting openings are designed according to the seaming process; c, foundation treatment and
cushion layer construction, namely, excavating out the soft soil of the
cushion layers of the channel, filling the
cushion layers with sand or broken stone and leveling, tamping in
layers till the compactness satisfying the design requirement is achieved, and pouring the cushion layers of the channels; d, surveying and positioning; e, hoisting in-position of the sectioned channels; f, connecting and fixing; and g, acceptance inspection. According to the construction process of the
precast concrete channel, the construction is convenient and rapid, the quality of the product is effectively controlled, and the influences of weather and geographical environments are eliminated; the construction speed is high, and the influences caused by mounting
civil engineering cross constructions are reduced to the minimum; good anti-permeability and anti-seismic property are achieved; the working plane is small, and the influences to the surrounding environment are low.
