Construction method for enabling shield tunneling machine to pass through concrete diaphragm wall to cross station
The invention discloses a construction method for enabling a shield tunneling machine to pass through a concrete diaphragm wall to cross a station. The method comprises the following steps: step I ofstopping to maintain pressure while the shield tunneling machine tunnels to a position which is 10 m in front of a first even wall for crossing the station; step II of performing first even wall construction; step III of enabling the shield tunneling machine to pass through the first even wall; step IV of enabling the shield tunneling machine to tunnel to cross the station, and assembling duct pieces for through seams; step V of performing second even wall construction; step VI of enabling the shield tunneling machine to pass through a second even wall; step VII of enabling the shield tunneling machine to continuously tunnel to a shield region to accomplish construction; and step VIII of enabling the shield tunneling machine to pass through a station main body structure to construct. The construction method has the beneficial effects of being convenient to operate, short in construction period, safe and economical, capable of solving the problem that starting and receiving conditions cannot be provided for the shield tunneling machine as the station cannot meet construction conditions under influences of land requisition and demolishing. The shield region can be firstly through, and then, the station is constructed, so that construction practicability is high, and therefore, the construction method can be widely applied to construction of a city subway shield tunnel.
本发明公开了一种盾构机穿越地连墙过站的施工方法,其方法为：步骤一、盾构机掘进至需穿越车站第一道地连墙前10m时停机保压；步骤二、第一道地连墙施工；步骤三、盾构机穿越第一道地连墙；步骤四、盾构机掘进过站，通缝拼装管片；步骤五、第二道地连墙施工；步骤六、盾构机穿越第二道地连墙；步骤七、盾构机继续掘进至盾构区间施工完毕；步骤八、盾构机穿越车站主体结构施工。有益效果：操作便捷、工期短，安全且经济，可解决车站受征地拆迁影响不具备施工条件，无法为盾构机提供始发和接收条件的问题；本发明盾构区间可以先贯通，后施工车站，施工实用性强，可广泛应用于城市地铁盾构隧道的建设中。
