- 摘要:
- CIPP（原位固化法）作為一種重要的非開挖管道修復(fù)技術(shù)，具有施工速度快、工期短、內(nèi)襯管與原管道緊密貼合、內(nèi)襯管連續(xù)且表面光滑等優(yōu)點(diǎn)，被廣泛應(yīng)用于污水管道、供水管道等給水排水管道的修復(fù)和更新。在充分調(diào)研國內(nèi)外對該技術(shù)的研究基礎(chǔ)上，重點(diǎn)介紹了近年來國內(nèi)外CIPP修復(fù)技術(shù)在彈性穩(wěn)定性、結(jié)構(gòu)剛度、強(qiáng)度（承載力）及管周土壓力等方面的研究情況，指出了目前在CIPP設(shè)計過程中存在的缺陷及未來的研究方向。簡要介紹了我國CIPP修復(fù)技術(shù)的工程實(shí)踐以及面臨的問題與挑戰(zhàn)，為進(jìn)一步研究內(nèi)襯管的結(jié)構(gòu)受力特性提供參考。
- Abstract:
- As an important trenchless pipeline repair technology, CIPP (Cured-In-Place Pipe) is widely used in the repair and renewal of sewage pipeline, and water supply pipeline and other water supply and drainage pipeline due to its advantages of fast construction speed, short construction period, tight fitting between the lining pipe and the original pipe, continuous lining pipe and smooth surface, etc. Based on a sufficient investigation of domestic and foreign research on CIPP repair technology, this paper reviewed the parameters of CIPP repair technology, including the elastic stability, structural stiffness, strength (bearing capacity) and peripheral earth pressure. This work points out the current defects in CIPP design and future research directions. In conclusion, we briefly introduce the engineering practice of CIPP repair technology in China, as well as the problems and challenges it faces, which could provide reference for further research on the mechanical characteristics of lining pipe.
