Construction method of concrete replaceable pavement for large aircraft test
The invention discloses a construction method of a concrete replaceable test pavement for a large aircraft test. The construction method comprises the following steps: S1, cutting a steel bar head on the side surface of a groove of a bearing platform (1), polishing and leveling an uneven place of concrete, chiseling the top surface of the concrete of the groove, and treating a net-shaped crack; s2, staking out in survey, re-checking the position and elevation of the groove, and pouring a fine aggregate concrete leveling layer; s3, laying a rubber plate; s4, side formworks are installed, reinforcing steel bars are bound, then end formworks are installed, and then concrete pouring, concrete surface galling, maintenance and end formwork disassembling are conducted; s5, when the concrete strength reaches 25%-30%, grooving is conducted; s6, the precast concrete test pavement panel is hoisted out, and edge covering angle steel is installed at the four longitudinal corners; s7, longitudinal expansion joint plates, prefabricated concrete test pavement plates and transverse joint plates are installed; and S8, longitudinal joint sealing materials are used for joint sealing. The method has the advantages of short construction period and high precision.
本发明公开了一种用于大飞机试验的混凝土可替换测试道面的施工方法，包括以下步骤：S1：对承台(1)凹槽侧面钢筋头切割及混凝土不平整地方打磨整平，凹槽混凝土顶面凿毛和网状裂缝处理；S2：测量放样，复核凹槽位置、标高，浇筑细石混凝土调平层；S3：铺设橡胶板；S4：安装侧面模板，绑扎钢筋，再安装端头模板，然后进行混凝土浇筑、砼面拉毛、养护、拆端头模；S5：在混凝土强度达到25％‑30％时刻槽；S6：吊出预制混凝土测试道面板，纵向四角安装包边角钢；S7：安装纵向胀缝板、预制混凝土测试道面板、横缝板；S8：纵向填缝料灌缝。具有施工周期短且精度高的优点。
