Inspection well spraying repair material and spraying repair process
The invention discloses an inspection well spray-coating repair material and a spray-coating repair process. The process comprises the following steps of: opening an inspection well cover, and performing ventilation; exploring the damage condition of an inspection well by using detection equipment, and determining that spraying repair can be carried out; laying a mesh bag at the bottom of the well, washing the wall of the inspection well with high-pressure water, and timely draining accumulated water at the bottom of the inspection well; preparing a repairing material; spraying the prepared repair material on the inner wall of the inspection well for multiple times by using a rotary spraying machine; after 24 hours, conducting flaw detection through detection equipment, rechecking the thickness of a spraying layer, the surface roughness, the surface flatness and the crack condition of the inner wall of the repaired inspection well, and conducting evaluation and analysis; and under thecondition that the repaired inner wall of the inspection well does not reach the standard, repeating the fifth step. In order to achieve structure reinforcement and function repair of the inspection well, modified mortar is produced, has good mechanical properties and good durability of permeability resistance and corrosion resistance, and also has the characteristics of being easy to construct and operate.
本发明公开了检查井喷涂修复材料及喷涂修复工艺，打开检查井盖，通风；用检测设备探查检查井破损状况，确定可以进行喷涂修复；井底铺设网袋，高压水冲刷检查井壁，并及时排掉检查井底积水；配制修复材料；通过旋喷机将配制好的修复材料多回次喷涂在检查井内壁；24小时后，用检测设备进行探伤检查，并复查修复后检查井内壁的喷涂层厚度、表面粗糙度、表面平整度和裂缝情况，并进行评估分析；若修复后检查井内壁未达标，重复第五步。本发明要达到对检查井的结构补强和功能修复，生产出一种改性砂浆，具备良好的力学性能和抗渗、抗腐蚀的良好耐久性，同时具备易于施工和操作的特性。
