According to Harding,(2017), Mixshield is a slurry tunnel boring machine (TBM) that uses an air bubble to control and support pressure at the face made by Herrenknecht. This is further explained by Herrenknecht. The TBM has an automatic air cushion that precisely controls the face support pressure in the excavation chamber (Herrenknecht,2024). It also offers an array of powerful cutting tools such as cutting knives and disc cutters. It is enhanced by jawcrushers positioned in front of the intake screen to further breakdown boulders and stones into conveyable size pieces (Herrenknecht, 2024). According to Herrenknecht and Rehm, the TBM can excavate and build a ring around the machine continuously (Herrenknecht and Rehm). This is supported by Herrenknecht’s claim that the TBM is able to do so with the help from its erector and thrust system. The erector is controlled by a remote and it positions the segments during ring building whereas the thrusters are positioned around the circumferen

Description on Herrenknecht mixshield s-1144                 Initially had an idea of an automatic rebar-tying robot, Tybot.  Did a brief search up but was not familiar with it as it was not used in Singapore. Someone in class asked if this project could be group work and the Prof said yes. Irham decided to form a group on a tunnelling machine used in the Deep Tunnelling Sewage System (DTSS). The idea was interesting and hence agreed to work with Irham on the tunnelling machine used in DTSS. After some research, the team found out that the specific brand and model of the tunnelling machine is called ' Herrenknecht Mixshield S-1144'.

Subject: Self-introduction Dear Professor Brad Blackstone, I hope this letter finds you well. My name is Chung Zhi Sheng, and I am one of your students in the critical thinking and communicating module. Having graduated from Singapore Polytechnic with a Diploma in Civil Engineering, I decided to pursue a civil engineering degree conferred by the Singapore Institute of Technology (SIT).  My interest in civil engineering is driven by my desire to contribute to the development of new infrastructure that can positively impact society. I believe that this module will provide me with the necessary skills to communicate my ideas more effectively, which is essential in the field of civil engineering. In terms of my communication strengths, I believe that I am clear and concise in conveying information. For instance, I can break down complex ideas into easily digestible chunks, focusing on the most important points and avoiding unnecessary jargon. This is particularly helpful when communicating

This quote suggests that even when engineers simplify their work to the general public and the efforts to break it down, the technical aspects remain a difficulty for public understanding. The technical details, even when simplified, might be too much for a non-technical audience to grasp. Having experienced this first-hand. The way to tackle this challenge is not to just break it down into simpler understanding. It is much more efficient to use analogies in their daily lives for the public to understand better. It is solely up to the engineers how imaginative they are to make the public understand via analogies.
