THE APPLICATION OF HIGH-PRESSURE SHOTCRETE ON THE DYKE CONSTRUCTION IN CHANGSHA |
| |
Abstract: | In according to prevent the hidden dangers of piping and leakage in the dyke with 21.8 km long along Xiangjiang River in Changsha and enhance theiv flood-proof ability , we repair and fasten it in the way of high-pressure shotcrete. This paper introduces the selection of instruments, adjustment of the distance of drill hole technological parameter, management of processes prospecting method of engineering quality and examination method. The prospecting results show that the method of high-pressure shotcrete is one of the better methods for deal with the flood-prevent bank of Changsha city. |
