GLOBAL UPWARD SHIELD MACHINE MARKET

INTRODUCTION

By controlling the rotational angles of arms so that the cutting edges of cutter bits can be vertically arranged in the rotation direction of excavating sections, as well as by controlling the cutting edges of the cutter bits and a center bit, the ground surface can be excavated in accordance with the change in soil when the ground surface is excavated in the upper direction.

To safely construct a vertical shaft by rotating a shell body tip cutter bit and a center bit to excavate earth and by discharging earth or something similar using a discharging means to provide a shell body with a jack, build the internal wall of the vertical shaft, and excavate in the upper direction.

RECENT DEVELOPMENT

A dedicated shield tunneling machine is used in the upward shield method to bore a shaft from an underground shield tunnel to the surface.

The method's development began with the objectives of developing a safer and more environmentally friendly tunneling method and removing the difficulty of land acquisition in densely populated urban areas.

Tunnels that can be constructed at greater depths, have curves with smaller radii, and are larger and more irregular in cross section thanks to recent technological advancements.

Multi-purpose underground conduits (branch shafts for gas pipes and cables), railroads (ventilation, maintenance, and escape shafts, and elevator shafts at stations), roads (ventilation and escape shafts), and underground structures (physical distribution shafts) can all be constructed using the method.

The technique can be used on soft rock, cohesive soil, sand-gravel soil, and sandy soil.It is able to produce shafts with a diameter of 2-4 meters and a depth of approximately 50 meters. The crucial aspect of this approach is that sections of the existing shield tunnel at the upward shield machine's entrance opening must be assembled in advance using shield machine-cuttable materials.

The muck discharge system of the machine makes use of pinch valves.A rubber sleeve that is inserted into the muck discharge pipe makes up these valves. The soil pressure at the shaft face and the volume of the muck discharge are controlled by changing the cross-sectional area of the pipe when the sleeve is inflated or deflated.

In Japan, shield tunnelling technology is crucial for underground building. In terms of safety and the breadth of its uses, the technology has advanced, and it is being used more frequently to build tunnels beneath cities. In the upward shield approach, a shaft is bored from an underground shield tunnel to the surface using a special shield tunnelling machine.

The method's creation was first aimed at solving the problem of finding land in highly populated urban areas as well as creating a safer and more ecologically friendly tunnelling technique. With the help of recent technological advancements, tunnels with larger, more asymmetrical cross sections, smaller-radius curves, and higher construction speeds are now possible.

In addition to building water supply and sewage systems (pipelines, water intake shafts, and maintenance shafts), multipurpose underground conduits (branch shafts for gas pipes and cables), railroads (ventilation, maintenance, and escape shafts, and elevator shafts at stations), roads (ventilation and escape shafts), and underground structures, the method can also be used to build water supply and sewage systems (physical distribution shafts.)

Cohesive soil, sandy soil, sand-gravel soil, and soft rock can all be treated with this technique. It can create shafts with a diameter of 2-4 m and a depth of roughly 50 m. The key aspect of this approach is that sections of the already-existing shield tunnel at the upward shield machine's entrance opening must be put together beforehand using materials that can be cut with the shield machine.

The muck discharge system on the machine makes use of pinch valves. These valves are made of a rubber sleeve that is mounted in the pipe used to discharge muck. The cross-sectional area of the pipe is altered by inflating or deflating the sleeve, which affects the soil pressure at the shaft face and the muck discharge volume.

Additionally, limited spaces can be used to build shafts, and once the machine reaches the surface, it can be retrieved for additional usage. This technique was initially used during the construction of a sewer, where holes ranging in depth from 20.3 to 32.8 m were built at three different places with a single shield tunnelling machine.

Pinch valves were utilised to discharge muck steadily during the sewer operation, and a polymer was added to help with the muck's plastic flow. Soil pressures at the shaft face might be successfully managed as a result. The ground around the shaft only moved a fraction of a millimetre.

Each shaft took around two months to build, of which one month was spent digging the shaft using the upward shield technique. These data showed how this shield technology holds promise for more applications in Japanese cities. (A).
