Description

A comprehensive corridor

technical field

The utility model belongs to the field of municipal construction engineering, in particular to a comprehensive pipe gallery.

Background technique

The traditional underground pipe gallery construction is usually in the following two ways: cast-in-place or factory prefabrication; all the work of the cast-in-place underground pipe gallery is completed on site, so the side walls and roof must be equipped with formwork, which not only causes a large number of formwork waste, and at the same time the construction period is long, all raw materials are transported to the site in bulk, and the on-site production will also damage and pollute the surrounding ecological environment. The method of on-site pouring requires high manual vibration. Microcracks are more likely to appear in the late stage of the corridor, which will leave hidden dangers of water leakage. The prefabricated pipe gallery is spliced on site by multiple prefabricated pipe sections. This method leads to many joints in the pipe gallery, and the waterproof requirements at the joints are high and difficult.

In the existing construction method of prefabricated integrated pipe gallery, the cushion layer is usually poured after grading and excavated to the design elevation, and the integrated pipe gallery is hoisted and then backfilled, which takes up a large area of land and a large amount of earthwork, and requires more Foundation pit drainage measures and other issues. This construction method is relatively feasible for the construction of new districts, but it has obvious disadvantages in terms of construction period and environmental disturbance for the reconstruction of municipal pipe networks in busy traffic areas.

To sum up, there is an urgent need to develop a cost-saving and easy-to-construct integrated pipe gallery.
