Reinforcing and lifting method for airport runway panel foundation

CUI TENGYUE

The invention relates to the technical field of reinforcing and lifting of airport runway panel foundations, and provides a reinforcing and lifting method of an airport runway panel foundation, which comprises the following steps: detecting the void settlement condition of a foundation below each panel of an airport runway; curtain holes are uniformly distributed in the peripheral edge of the first pavement slab corresponding to the foundation subjected to void settlement at intervals; the periphery of the first pavement slab is connected with the second pavement slab, and curtain holes are uniformly distributed in the edge of one side, connected with the first pavement slab, of the second pavement slab at intervals; grouting the curtain hole to form a support curtain for supporting the first pavement slab and the edge of the second pavement slab adjacent to the first pavement slab; and vertically and downwards drilling holes in the first pavement slab, and respectively carrying out deep grouting lifting and shallow grouting leveling on the void settlement area and the corresponding first pavement slab according to different drilling depths. Accurate detection and accurate reinforcing and lifting are conducted on the pavement slab and the foundation below the pavement slab, the construction efficiency is effectively improved, and the structural strength and the service life of the airport runway are guaranteed.

本发明涉及机场跑道路面板地基加固抬升技术领域，提供一种机场跑道路面板地基的加固抬升方法，包括：检测机场跑道各路面板下方地基的脱空沉降情况；在发生脱空沉降的地基对应的第一路面板的四周边缘均匀间隔布设帷幕孔；第一路面板四周分别连接第二路面板，在第二路面板连接第一路面板的一侧边缘均匀间隔布设帷幕孔；向帷幕孔内注浆，形成支撑第一路面板以及紧邻第一路面板的第二路面板边缘的支座帷幕；在第一路面板上竖直向下钻孔，根据不同的钻孔深度分别进行脱空沉降区域及与其对应的第一路面板的深层注浆抬升和浅层注浆找平。本发明针对路面板及以下地基进行精准检测和精确加固抬升，有效提升施工效率，保证机场跑道的结构强度和使用寿命。
