摘要:
管片拼装法检查井修复技术是对管片拼装法管道修复技术的延伸开发，具有修复后结构强度高、抗腐蚀性强、施工无需大型机械设备、噪声低等优势，可适用于多种施工环境。管片拼装完成后，通过对内衬与既有检查井缝隙注浆形成复合井结构。因片材采用透明PVC塑料，可以目视注浆填充情况，故能有效保证施工质量。结合上海市宝山区呼兰路（西泗塘河）污水倒虹管及检查井非开挖内衬修复工程，对比分析了大中型排水检查井非开挖内衬修复中几种施工技术的特点，阐述了管片拼装技术在大中型检查井修复施工中的关键控制点和技术优势，并展望了管片拼装法在大中型检查井修复方面的应用前景。
Abstract:
Manhole segment assembling technology is an extension of pipe segment assembling repairing technology, which has advantages of high structural strength, strong corrosion resistance after repairing, installation without large mechanical equipment, low noise and applicable for various construction environments. After segments are assembled, the composite manhole structure is formed by grouting the gap between liners and existing manhole. Because segments are made of transparent PVC plastics, the grouting condition can be checked visually, and installation quality can be guaranteed effectively. Combining with trenchless rehabilitation projects of sewerage inverted siphon and manhole in Hulan Road (Xisitang River), Baoshan District, Shanghai, this paper compares and analyzes the advantages and disadvantages of several trenchless rehabilitation methods commonly applied in large and medium drainage manhole, and elaborates the key controlling point and technical advantages of segment assembling method. Finally, the application prospect of segment assembling method in large and medium manhole rehabilitation is provided.
