Tunnel main body engineering construction method
The invention discloses a tunnel main body engineering construction method. The method comprises the following steps: detecting a pile body; top beam and support construction; excavating a foundation pit; cleaning the foundation pit; constructing a cushion layer; performing waterproof construction on a cushion layer; constructing a structural bottom plate; erecting an inner bracket; constructing a structural side wall; constructing a structural top plate; performing waterproof construction on a structural side wall and a top plate; and main body structure foundation pit backfilling. According to design requirements, enclosure structure construction is expanded outwards according to a construction process, so that the thickness of the side wall of the main body structure, enclosure structure construction and side lines of the enclosure structure are expanded outwards by 10 cm, the thickness of the side wall should be 10 cm thicker than the design when the side wall of the main body structure is constructed, and the quality target is qualified; and national and industrial current related construction quality acceptance specifications and design requirements are met, and one-time acceptance of the quality is ensured to be qualified.
本发明公开了一种隧道主体工程施工方法，包括以下步骤：桩体检测；冠梁及支撑施工；基坑开挖；基坑清槽；垫层施工；垫层防水施工；结构底板施工；内支架搭设；结构侧墙施工；结构顶板施工；结构侧墙及顶板防水施工；主体结构基坑回填。该发明根据设计要求，围护结构施工根据施工工艺进行外扩，以确保主体结构侧墙厚度，围护结构施工，围护结构边线均外扩10cm，因此施工主体结构侧墙时侧墙厚度应比设计厚10cm，质量目标合格，达到国家及行业现行有关施工质量验收规范及设计要求，确保质量一次性验收合格。
