Description

  The present invention relates to a start shaft used when a shield propulsion unit and a propelling pipe are laterally moved from a lateral pulling portion provided adjacent to a starting portion on a planned route of a tunnel to a starting portion and installed on the planned route. The present invention relates to a lateral movement facility, a method for installing a mud pressure shield propulsion machine using the lateral displacement facility, and a propulsion method.

  In the propulsion method that forms a tunnel consisting of a number of propulsion pipes connected in the ground by pushing the shield propulsion machine and the propulsion pipes into the ground while sequentially connecting the propulsion pipes from the rear of the shield propulsion machine For example, when a tunnel is formed in a portion directly under the road while ensuring traffic of the vehicle, it is not possible to provide an opening for the start shaft on the planned route. For this reason, as shown in FIG. 1, for example, the portion directly above the start portion 51 of the start shaft 50 located on the planned route L is covered with a large number of lining plates 53 arranged vertically and horizontally to allow the vehicle to pass. The lateral pulling portion 52 is provided at a position off the road adjacent to the starting portion 51, and the upper portion of the lateral pulling portion 52 serves as an opening, and the propulsion pipe is passed through the opening of the lateral pulling portion 52. 11 and other equipment have been devised so that they can be carried into the start shaft 50.

Further, the propulsion pipe 11 and the like carried into the start shaft 50 using a crane or other lifting machine is moved laterally to the start portion 51 on the planned route L through the opening of the horizontal pulling portion 52 and then into the ground. It is necessary to push in.

  On the other hand, it is necessary to carry a shield propulsion machine to the start shaft and install it on the planned route of the tunnel. The shield propulsion machine is a heavy object having a weight of about 60 t, for example, and has a considerable weight and size compared to the weight and size of the propulsion pipe (for example, about 15 t). Therefore, it is difficult to move from the lateral pulling portion to the starting portion. That is, when assembling the shield propulsion unit in the horizontal pulling unit using a crane or other heavy lifting machine installed on the ground, when moving it to the starting unit, for example, laying an iron plate at the bottom of the starting shaft reduces friction resistance In this state, a large moving facility is required inside the start shaft such as a method of pulling and moving using a large number of winches having a large tensile force, and a lot of labor and labor are required.

  In addition, the shield propulsion machine can be divided into multiple parts and loaded into the horizontal section of the start shaft, and each part can be moved laterally and then assembled at the start section. In addition to being unable to use a lifting machine such as a crane installed on the ground, it is difficult to perform assembly work because of its narrow space. In particular, when the shield propulsion device is a mud pressure shield propulsion device that discharges soil from the face using a screw conveyor, the screw conveyor is long, so that the assembly work becomes even more difficult.

  Furthermore, in the propulsion method, it is necessary to install a propulsion jack such as a multistage jack that propels the shield propulsion device by extending the reaction force from the reaction wall behind the shield propulsion device on the planned route. The propulsion jack also has a considerable weight of, for example, about 30 tons, so that the operation of moving the propulsion jack from the lateral pulling portion to the starting portion requires a large moving facility inside the starting shaft. As a result, it takes a lot of labor and labor.
