Abstract

Abstract:

As compared with the conventional methods to repair tunnel diseases, the casting of light soil to the cavities at the tunnel lining back is more effective. In this paper, the advantages of casting equipment including MT-FQG wind-pressure pouring bottles were analyzed according to the characteristics of light soil, and the engineering characteristics and parameters for foamed light soil were determined. Moreover, a new up-casting construction technique was proposed, which consists of several key steps such as the boring, the second pouring, the pouring and the checking. The proposed technique was finally applied to the filling construction of large-scale cavities in Houmen Tunnel, the results indicating its economic value.

Key words: tunnel, disease repairing, light soil, perfusion equipment
