More Information
Summary:The invention belongs to the technical field of building and municipal engineering construction, and particularly relates to a manhole cover synchronous-lifting construction process. An lining ring isadditionally arranged on the basis of an existing adjustment ring, and stiffening rib grooves and rotating shaft grooves are formed in the lining ring, so that a manhole cover and the adjustment ringare always clamped and limited together, the manhole cover can be synchronously lifted and mounted through construction using the adjustment ring and road base layer paving, the construction qualityis stable and reliable, the material saving and environment-friendly effects are achieved, asphalt mixtures around the manhole cover are efficiently paved and compacted, the overall consistency and flatness of a road structure layer are ensured, road surface driving is comfortable, and the structure is safe and reliable. 本发明属于建筑和市政工程施工技术领域，具体涉及到一种检查井盖同步提升施工工艺，本发明在现有调节环的基础上增设了内衬环，并在内衬环上设有加劲肋凹槽和转轴凹槽，使得检查井盖的与调节环之间始终卡合限位在一起，使用此
