Anti-sedimentation inspection well replacement process

An anti-sedimentation inspection well replacement process is characterized by including the following steps that firstly, an anti-sedimentation concrete cover plate (1) is prefabricated, wherein the anti-sedimentation concrete cover plate (1) is of a reinforced concrete structure; and secondly, road cutting is conducted, wherein road cutting is conducted with a well chamber as the center according to the rule that the length of each side of the anti-sedimentation concrete cover plate (1) is increased by 200 mm, an existing well lid frame is removed, and chiseling is conducted on the periphery. The anti-sedimentation inspection well replacement process is easy to construct, time is saved, operation is convenient, the influence on traffic flow is small, and the anti-sedimentation inspection well replacement process can be suitable for old well lid replacement of vast urban and rural areas. 种防沉降检查井换装工艺，其特征是包括以下步骤：步骤1)预制防沉降混凝土盖板(1)，防沉降混凝土盖板(1)为钢筋混凝土结构；步骤2)路面切割：以井室为中心，按照防沉降混凝土盖板(1)的大小每边增加200mm的长度进行切割路面，去除原有的井盖框，对四
