Constricted space tunnel construction method
The invention relates to a restricted space tunnel construction method. The construction method for the tunnel in the limited space comprises the steps that S102, a stand column pile structure is constructed; s104, a supporting structure is constructed; step S106, carrying out segment division based on an open section and a buried section of the tunnel, reserving core soil in a middle segment, and carrying out reinforcement treatment on the core soil; s108, after other sections are excavated, tunnel structure bottom plates of the other sections are sequentially constructed, and finally reserved core soil of the middle section is excavated; s110, side walls are constructed from the two ends to the middle section; and S112, the support and the stand column pile structure are dismantled, earthwork backfilling is conducted, and construction is completed. According to the construction method for the tunnel in the limited space, the problems that the middle section is difficult to transport and the construction period is long can be effectively solved, the stability of the foundation pit can be improved, and the method has wide application space and very high popularization value in the technical field of open cut tunnel construction and even other similar fields.
本发明涉及一种受限空间隧道施工方法。该受限空间隧道施工方法，该方法包括，步骤S102，施工立柱桩结构；步骤S104，施工支撑结构；步骤S106，基于隧道的敞口段与暗埋段进行节段划分，于中间节段内预留核心土，并对核心土进行加固处理；步骤S108，开挖其他节段后，施工依次施工其他节段隧道结构底板，最后开挖中间节段的预留核心土；步骤S110，由两端向中间节段施工侧墙；步骤S112，拆除支撑与立柱桩结构，土方回填，完成施工；该受限空间隧道施工方法，既能有效解决中间节段运输困难、施工工期长的问题，又能提高基坑稳定性，该方法在明挖隧道施工技术领域甚至其他类似领域中均具有广阔的应用空间和很高的推广价值。
