Construction method for preventing underground tunnel from floating upwards
The invention relates to a construction method for preventing an underground tunnel from floating upwards, which belongs to the technical field of building construction, and comprises the following steps: S1, an excavation stage: performing segmentation and block-by-block skip excavation, forming vacant sections by excavated sections, forming load sections by non-excavated sections, the upper part of the underground tunnel is integrally in a spaced distribution state that one section is anti-floating and meets the requirement and the other section is insufficient in soil covering; s2, construction of a bottom plate, side walls and a top plate of the engineering structure above the vacant section is completed, after certain strength is achieved, fender post steel bars are smashed out along the periphery of the top plate, and then concrete is poured; and S3, construction of the engineering structure above the vacant section is completed, a load section is formed after ballasting, earthwork of the original load section is excavated to form the vacant section, and construction is completed according to the step S2. The method has the effect of improving the safety.
本申请涉及一种防止地下隧道上浮的施工方法，属于建筑施工的技术领域，其包括以下步骤：S1、开挖阶段：分段、分块跳仓开挖，开挖的段落形成空置段，未开挖的段落形成荷载段，地下隧道上方整体呈一段抗浮满足要求、一段覆土不足的间隔分布状态；S2、空置段上方工程结构底板、侧墙、顶板施工完成，达到一定强度后，沿顶板四周砸出围护桩钢筋，然后浇筑混凝土；S3、空置段上方工程结构施工完成，压载后成为荷载段，将原荷载段土方开挖成为空置段，并按照上述步骤S2完成施工。本申请具有提高安全性的效果。
