The beneficial effects of the utility model reside in that:
1. adopt prefabricated construction, the availability factor is high, avoids making, maintaining at job site construction, practices thrift construction cycle, and this utility tunnel has cancelled special escape canal simultaneously, practices thrift manufacturing cost.
2. The structural form that the reinforced concrete pipe gallery body is wrapped by the high-density polyethylene plate is adopted, so that the reinforced concrete structural layer is prevented from directly contacting natural soil, and the corrosion of the structural layer is avoided; the high-density polyethylene plate and the reinforced concrete structure layer are integrally formed, so that the anti-seepage performance of the reinforced concrete structure can be enhanced, underground water is prevented from permeating into the pipe gallery, and the maintenance work of accumulated water of the pipe gallery is reduced.
3. Interface intensity is big, and difficult dislocation drops, and during the concatenation of adjacent utility tunnel section, the high density polyethylene board passes through high density polyethylene welding rod annular welding, forms airtight structure, and the intensity of welding interface generally is 1.8 times of former interface intensity, can better bear the stress that the kneck subsides the production because of the ground.
