伊麗莎白港采用非開挖技術由非開挖技術有限公司管理的一支隊伍承擔了位于南非伊麗莎白港商務區中心兩條平行的污水管道的修復工程。開始設計時，計劃在整個工程中采用螺旋纏繞修復技術。但后來，施工人員很快就發現，由于現場施工條件的限制，在某些部分需要采用原位固化（翻轉內襯）修復技術和爆管技術。
為了順利地完成這個工程，總共采用了五種不同的非開挖修復技術，即：緊配合的纏繞技術、原位纏繞技術、常溫固化的翻轉內襯技術、紫外線固化的翻轉內襯技術和爆管技術。該工程是采用非開挖技術在不開挖路面，不干擾交通的條件下，成功處理未曾預料到的現場條件的最好工程實例。

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.

頂管掘進機的研磨工具該研磨工具設置在泥水平衡頂管機內，可以切割金屬障礙物，例如以前市區開發項目遺留在地下的PC或鋼管。
研磨工具由數個設備組成，以便安全地切割地下金屬障礙物，并將碎片排入頂管機內，包括：（1）探測技術，確定金屬障礙物的位置及距離；（2）加固技術，固定障礙物，保護周邊環境；（3）切割技術，推出切削鉆頭，采用低速鉆進的方式切除障礙物。
該研磨工具提高了通過金屬障礙物的能力，大大簡化了地下開發工程的施工過程，因為不再由于地下金屬障礙物的存在而改變路徑或者采用成本較高的特殊施工方法。

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.

智能切割裝置在芬蘭，原位固化內襯（翻轉內襯）修復技術是修復家庭排水系統的理想方法，包括修復小口徑的廚房和浴室排水系統。重新將這些小口徑排水管道連接到分支管道需要一種創新的解決方法。智能切割裝置可以提供這種需要。
智能切割裝置有幾個部件，使用戶可以適應特殊的管道尺寸和幾何條件。它可以由磨碎機或手鉆驅動，輪軸與管道的直徑匹配。前方的鉆頭和側向研磨板均裝在輪軸上，然后置入待開口的分支管內，接上電源即可開始切割。一旦切割裝置通過內襯壁，將其個裝置拉回，并用更換鉆頭。重新將智能切割裝置置入分支管，用回轉的研磨板研磨掉內襯邊緣的剩余部分，恢復與分支管道的連接連接。

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.

翻轉內襯污水管道修復的評價一支多學科的研究隊伍承擔了美國歷史上的第一項試驗研究項目，以評價25年前用翻轉內襯法修復的管道性能。該實驗測試了內襯的11項性能，包括：彎曲強度和彎曲模量。所有的彎曲強度值均超過了美國材料試驗協會（ASTM）規定的最低標準，并且都在較窄的范圍內變化。
除了兩個樣品外，彎曲模量值也在美國材料試驗協會（ASTM）規定的最低標準之上。管道性能的變化似乎是由于內襯的變化引起的，而不是隨著時間而發生了變化。該項研究表明，修復的管道還處在良好的狀態，應該可維持到其設計的50年壽命，也許還會超過。

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.

管棚施工技術的模擬該論文是Veronika Onderkova畢業論文的總結，目的是模擬和評價使用微型頂管技術進行管棚施工以修復捷克的Jablunkov鐵路隧道。
研究使用了二維的Plaxis V8（FEM）軟件來模擬和比較不同修復技術的結果，計算剩余壁厚的承載能力和被動土壓力等。由于隧道所處位置的地質和水文條件很復雜，分析極具挑戰性。研究的結果確認了使用微型頂管進行管棚施工來修復該隧道的選擇。
象任何復雜情況下的模擬一樣，該項目也存在有待進一步提煉和研究的課題。然而，該項研究結果確認了這種方法是設計的一種評價工具。

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.
