伊丽莎白港采用非开挖技术
由非开挖技术有限公司管理的一支队伍承担了位于南非伊丽莎白港商务区中心两条平行的污水管道的修复工程。开始设计时,计划在整个工程中采用螺旋缠绕修复技术。但后来,施工人员很快就发现,由于现场施工条件的限制,在某些部分需要采用原位固化(翻转内衬)修复技术和爆管技术。
为了顺利地完成这个工程,总共采用了五种不同的非开挖修复技术,即:紧配合的缠绕技术、原位缠绕技术、常温固化的翻转内衬技术、紫外线固化的翻转内衬技术和爆管技术。该工程是采用非开挖技术在不开挖路面,不干扰交通的条件下,成功处理未曾预料到的现场条件的最好工程实例。

Port Elizabeth Goes Trenchless
A team managed by Trenchless Technologies cc undertook the rehabilitation of two parallel sewers located in the heart of the Port Elizabeth’s Business District in South Africa. Originally designed to use the spiral wound technique throughout the project, the team soon discovered that site conditions required also using CIPP and pipe bursting at certain locations.
Altogether, the project used five different trenchless techniques – spiral wound expanded to a close fit, spiral wound in-place, ambient cured-in-place pipe, UV cured-in-place pipe and pipe bursting to successfully complete the project. This project is an excellent example of using trenchless technology options to address unanticipated site conditions allowing the project to be completed successfully without excavation and surface disruption.

Milling Mole
The Milling Mole method is a sludge-based jacking method that is capable of cutting metal obstructions such as PC or steel piles left in the earth from previous urban development projects.
The Milling Mole system combined several pieces of equipment used to safely cut subsurface metal obstructions into a tunneling machine including (1) inspection technology to determine the presence of metal obstructions and the distance to the obstructions, (2) improvement technology to fix the obstructions and secure the surrounding area, and (3) cutting technology to cut the obstructions by pushing a cutting bit into the obstructions using low-speed boring.
The enhanced capability of the Milling Mole method to tunnel through metal obstructions greatly simplifies the construction process associated with underground urban development projects, since metal obstructions in the earth no longer force routes to be changed or expensive specialist construction processes to be carried out.

智能切割装置
在芬兰,原位固化内衬(翻转内衬)修复技术是修复家庭排水系统的理想方法,包括修复小口径的厨房和浴室排水系统。重新将这些小口径排水管道连接到分支管道需要一种创新的解决方法。智能切割装置可以提供这种需要。
智能切割装置有几个部件,使用户可以适应特殊的管道尺寸和几何条件。它可以由磨碎机或手钻驱动,轮轴与管道的直径匹配。前方的钻头和侧向研磨板均装在轮轴上,然后置入待开口的分支管内,接上电源即可开始切割。一旦切割装置通过内衬壁,将其个装置拉回,并用更换钻头。重新将智能切割装置置入分支管,用回转的研磨板研磨掉内衬边缘的剩余部分,恢复与分支管道的连接连接。

Smart Cutter™
In Finland, cured-in-place lining offers a good solution for the renovation of household drains, including smaller kitchen and bathroom drains. Reconnecting these smaller drains to the lateral requires an innovative solution. The Smart Cutter™ addresses this need.
The Smart Cutter™ offers a number of components that allow the user to match specific size and geometric conditions of the pipes. The Cutter may be powered by either a grinding machine or hand drill. A hub is matched to the pipe diameter profile. A front-facing drill head and side grinding panels are loaded onto the hub and inserted into the lateral to be reopened. Power is applied and the cutting begins. Once the cutter passes through the liner wall, the cutter is pulled back the drill head removed and replaced with a blank end. The Smart Cutter™ is inserted back into the lateral where rotating panels grind away the remaining of the liner edges reinstating the connection.

翻转内衬污水管道修复的评价
一支多学科的研究队伍承担了美国历史上的第一项试验研究项目,以评价25年前用翻转内衬法修复的管道性能。该实验测试了内衬的11项性能,包括:弯曲强度和弯曲模量。所有的弯曲强度值均超过了美国材料试验协会(ASTM)规定的最低标准,并且都在较窄的范围内变化。
除了两个样品外,弯曲模量值也在美国材料试验协会(ASTM)规定的最低标准之上。管道性能的变化似乎是由于内衬的变化引起的,而不是随着时间而发生了变化。该项研究表明,修复的管道还处在良好的状态,应该可维持到其设计的50年寿命,也许还会超过。

Retrospective Evaluation of CIPP Sewer Rehabilitation
A multi-discipline team undertook the first-ever study in the US to assess the long-term performance of cured-in-place pipes that had been installed up to 25 years ago. Tests were conducted on 11 properties of the liners including flexural strength and flexural modulus. All flexural strength values exceeded ASTM minimum standards and generally fell within a narrow range.
Except for two samples, the flexural modulus values were above the ASTM minimum standard. The variation in pipe performance appears to result from variability within the liner rather than a change over time. The study showed that the pipes appeared to be in good condition and should last their designed 50-year life and perhaps well beyond.

管棚施工技术的模拟
该论文是Veronika Onderkova毕业论文的总结,目的是模拟和评价使用微型顶管技术进行管棚施工以修复捷克的Jablunkov铁路隧道。
研究使用了二维的Plaxis V8(FEM)软件来模拟和比较不同修复技术的结果,计算剩余壁厚的承载能力和被动土压力等。由于隧道所处位置的地质和水文条件很复杂,分析极具挑战性。研究的结果确认了使用微型顶管进行管棚施工来修复该隧道的选择。
象任何复杂情况下的模拟一样,该项目也存在有待进一步提炼和研究的课题。然而,该项研究结果确认了这种方法是设计的一种评价工具。

Modeling of Pipe Roofing Technology
The paper summarizes the thesis study undertaken by Veronika Onderkova to model and evaluate pipe roofing using microtunneling to rehabilitate the Jablunkov railroad tunnel in the Czech Republic.
The study used 2D Plaxis V8 (FEM) software to model and compare results of alternative rehabilitation technologies. The model calculated the bearing capacity of the retaining wall, passive earth pressures, etc.
The analysis was particularly challenging given the complex geological and hydrogeological conditions of the tunnel location. The study results validated the project team’s selection of a pipe roofing arch using microtunneling for rehabilitating the Jablunkov tunnel.
As with any modeling of this complexity, there are issues that require further refinement and research. However, the research results of this study produced reasonable results that seem to validate this approach as a design assessment tool.
