The Cutter Head of Tunnel Boring Machine (TBM) doubt “Kaunlaran” is the first of the six (6) TBMs to be used for the partial operability section of Metro Manila Subway Project (MMSP), the country’s first underground railway system.

Cutter force measurement on tunnel boring machines

Loading of a disk cutter on tunnel boring machines (TBM) is usually estimated from global machine thrust. In order to be able to measure cutting forces of an individual disk cutter, a new...

Wear Analysis of Disc Cutters of Full Face Rock Tunnel

In the field the wear prediction method commonly used is based on the excavation length of tunnel boring machine (TBM) to predict the disc cutter wear and its wear law, considering the location...

Theoretical prediction of wear of disc cutters in tunnel

2019-2-1  Predicting the cutter consumption and the exact time to replace the worn-out cutters in tunneling projects constructed with tunnel boring machine (TBM) is always a challenging issue. In this paper, we focus on the analyses of cutter motion in the rock breaking process and trajectory of rock breaking point on the cutter edge in rocks.

Tunnel Boring Machine 2 Types Of Tunnel Boring Machine

Types of Tunnel Boring Machine. The tunnel boring machine can be classified into the following types: 1. Hard Rock Tunnel Boring Machine. As the name itself implies, the hard rock tunnel boring machine is used to excavate the tunnels in hard rock. They are provided with disc cutters mounted in the cutter

5 Different Types of Tunnel Boring Machines (TBMs

2018-10-10  The cutter-head is the same size as the tunnel diameter, and the machine works by thrusting disc cutters into the rock while the cutter-head rotates. The combination of high thrust and rotation chips away at the rock allowing the machine

All About Tunnel Boring Machine Components, Types

2019-3-13  Now that we know what a TBM is, and, it’s types, let’s talk about how a Tunnel Boring Machine works. The cutter head on the TBM rotates and thrusts into

Analyses of dynamic characteristics and structure

2016-9-8  Therefore, it is of great theoretical value and engineering significance to analyze the dynamics characteristics of tunnel boring machine (TBM) cutter system, optimize cutter structure, and improve the anti-vibration capability.

Cutter Instrumentation System for Tunnel Boring Machines

2017-5-31  a tunnel boring machine includes rotational data, vibration data, and temperature. Rotational Data Knowing the cutter rpm provides an indication of how smoothly the cutters are performing. Rotational data can be used to detect cutter conditions but

Cutter for tunnel boring machine Narvestad, Stein

A cutter for a tunnel boring machine is equipped with a cutter body (1) with a slanting surface (2), a cylindrical contact surface (12) and a preferably tapered threaded portion with specially designed threads (6), a clamping ring (4) with threads adapted to the cutter body's threads with a slanting surface (5) with a groove (13) with a spring (14).

Cutter force measurement on tunnel boring machines

The cutter head of a tunnel boring machine may be trapped in extremely adverse geological environments, which requires a large enough driving torque to get rid of the trapped condition. In this

All About Tunnel Boring Machine (TBM) & Parameters

2016-5-12  Tunnel Boring Machine (TBM) A TBM is a massive set of complex equipment assembled together to excavate a tunnel, often called as “Mole”. Major components of this Tunnel Boring Machine includes. Cutter head, with cutting discs/tools and; Muck buckets to carry and dispose excavated muck; Power supply Systems; Cutter head rotation & thrust

Kaunlaran tunnel boring machine The Philippines Today

2021-2-4  “Kaunlaran” tunnel boring machine (TBM) Tomorrow, February 5, 2021, the 74-ton CUTTER HEAD of “Kaunlaran,”—the first among the 6 Tunnel Boring Machines (TBMs), which will be used in building the partial operability section of the METRO MANILA SUBWAY, WILL FINALLY ARRIVE!

Introducing an empirical model for prediction of disc

2021-3-4  Disc cutters wear and need to be replaced when using tunnel boring machines (TBMs) to excavate through rock, often becoming a high ticket item on the list of consumables in tunneling operation. The empirical models used for predicting cutter life are commonly based on the properties of intact rock, while the impact of rock mass characteristics on cutter wear is often ignored or not properly

Remote Disc Cutter Monitoring in Tunnelling tunnel

A constant cutter RPM indicates that the cutter bearings and seals are functioning properly, and also indicates that the rock being bored is competent and without major variations. A variable RPM provides a warning to the operator of possible undesirable situations, including a locked-up cutter, improper machine thrust, or blocky ground.
