−プンシ−ルド機を駆動するための機構に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open shield method for burying relatively small-diameter pipes such as sewer pipes, water pipes, gas pipes, and electric / communication cable pipes. The invention relates to a mechanism for driving a punshield machine.

ルド−ザにより行なう。2. Description of the Related Art For example, when a sewer pipe is buried by an open shield method, conventionally, an excavator, for example, a backhoe is arranged on a road ahead in an advancing direction of the open shield machine, and the backhoe is used to operate the excavator. -Excavating the inside of the Punshield. For backfilling, backfill soil carried by a dump truck is carried out by bulldozer.

を布設していく。The operation of the open shield machine is performed by a dedicated operator using the power unit of the open shield machine. Then, a sewer pipe is laid in the space inside the open shield machine formed by repeating excavation, backfilling, and compaction of the backfill soil performed by the propulsive reaction force of the open shield machine.

レ−タの数が多くなって、コストアップにつながる。[0004] By the way, if it is almost unavoidable in Japan that heavy traffic such as dump trucks and backhoes are arranged in tandem in places where traffic is frequent compared to the width of the road, the work range becomes wide and traffic obstacles and traffic obstacles occur. Safety issues arise. Further, when the excavated soil is used as the backfill soil as it is, the excavated soil must be transported by a dump truck, so that the working efficiency is significantly reduced. Another characteristic of the open shield method is that since a series of heavy working machines proceed integrally, the number of heavy working machines, operating devices, and operators increases, leading to an increase in cost.

４８８号）。Therefore, when burying small-diameter pipes by the open shield method, efficient backfilling and elimination of heavy machinery and operating devices shorten the long tandem arrangement of working heavy machinery and reduce the operating cost. The applicant has applied for a patent under the name of "open shield method for burying small diameter pipes" (Japanese Patent Laid-Open No. 7-42).

点にある。[0006] The feature of the above construction method is that an excavator is arranged across the open shield machine in the traveling direction of the open shield machine, and the inside of the open shield machine is moved in the traveling direction. Excavating with an excavator, the excavated soil is back-turned by turning the excavator and backfilled, and the operation of the open jack propulsion jack is performed through the power unit of the excavator. .

きた。The following effects were obtained by the above method. That is, since it is sufficient to dispose the excavator across the open shield machine and the earth and sand transporter in front of the excavator, the front and rear length of the working range is shortened. In the backfill, the excavated soil was diverted to the backfill soil by using an excavator, so that the heavy equipment for backfill could be omitted. Further, since the operation of the open shield machine is performed by the operator of the excavator operating the power unit of the excavator, the operator exclusive to the open shield machine can be omitted.

ことになる。However, since the propulsion jack is operated via the power unit of the excavator, the jack stroke of the propulsion jack is limited by the amount of oil of the excavator. As a result, the directional control performance of the open shield machine is reduced and the excavation efficiency is reduced.
