Zusammenfassung: | The invention provides a construction method of a station entrance-exit main body structure close to urban buildings and roads. The construction method specifically includes the steps that a first open-excavated vertical shaft is constructed, an underground-excavated channel is constructed and a second open-excavated vertical shaft is constructed, wherein the first open-excavated vertical shaft and the second open-excavated vertical shaft both are excavated through an upside-down well wall method and the first open-excavated vertical shaft is excavated to the location of the underground-excavated channel, the excavated area of the underground-excavated channel is subjected to deep hole strengthening grouting and is strengthened by erecting a pipe roof bracket, then a CRD construction method is adopted to construct the underground-excavated channel, after the first open-excavated vertical shaft and the underground-excavated channel are constructed, the other open-excavated areas are excavated while the second |
