Underground pipe gallery construction method
The invention discloses an underground pipe gallery construction method. The underground pipe gallery construction method comprises the following steps that S1, a temporary road is arranged on one side of a main road; S2, a foundation pit is excavated in the road surface of the main road on the other side of the temporary road, and a side slope, close to the temporary road, of the foundation pit is supported; and S3, a retaining wall is arranged at the end of a constructed underground pipe gallery, then the foundation pit on the side is backfilled, then a main roadbed and a water stabilizing layer are arranged, and after the main road is returned to pass, the underground pipe gallery is turned to the other side of the main road to be constructed according to the step S1. Shield construction is adopted between the step S1 and the step S2 to construct a soil body of the section part of the pipe gallery, and the soil body of the section part of the pipe gallery subjected to shield construction is located on the lower portion of the foundation pit excavated in the step S2. According to the underground pipe gallery construction method, the mode of combining open excavation and underground excavation is adopted, various defects of an open excavation method are avoided, the stability of the foundation pit is improved, the construction period of the underground pipe gallery when the underground pipe gallery passes through the urban main road is effectively shortened, the construction cost is greatly reduced, and the construction safety of the underground pipe gallery is improved.
本发明公开了一种地下管廊施工方法，包括以下步骤：步骤S1、于干道一侧设置临时道路；步骤S2、于临时道路的另一侧干道路面开挖基坑，并于基坑靠近临时道路的一侧边坡进行支护；步骤S3、于已施工地下管廊的端部设置挡土墙，再对该侧基坑进行回填，而后设置主路基及水稳层，并回复干道主路通行后，转向另一干道侧按照所述步骤S1进行施工；所述步骤S1与步骤S2之间采用盾构施工管廊断面部分土体；所述盾构施工的管廊断面部分土体位于步骤S2开挖基坑的下部。本发明采用明挖与暗挖相结合的方式，避免了明挖法的各种弊端，又提高了基坑的稳固性，有效缩短了地下管廊穿越城市干道时的施工周期，大幅度降低了施工成本，并且改善了地下管廊施工安全。
