Embodiment Construction

[0027] The transportation method of the present invention is different from conventional transportation in that the transportation system can continuously supply materials to medium-diameter and long-distance tunnels, maximize the tunneling speed of the shield machine, and increase the engineering cost little. Therefore, it is instructive for projects with tight schedules and difficult construction.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] See figure 1 , which is a flow chart of an embodiment of the rapid transportation method for medium-diameter and long-distance tunnel shield construction of the present invention, which includes the following steps:

[0030] S101, setting a mobile platform at the working wellhead.

[0031] S102, laying monorail in the tunnel.

[0032] S103, based on the horizontal transportation time, add a fixed branch in the tunnel.

[0033] S104, multiple transport vehicle...

Abstract

The invention provides a quick transportation method in medium-diameter and long-distance tunnel shield construction. The method comprises the following steps of: (1) arranging a movable platform on a working well mouth to allow empty vehicles and loaded vehicles to pass mutually; (2) paving a monorail in a tunnel; (3) arranging a fixed turnout in the tunnel additionally according to the horizontal transportation time; and (4) transporting according to a transportation rule by using a plurality of transportation vehicles. By adopting the transportation method of the invention, the construction period can be shortened substantially on the premise of ensuring safety, and the transportation method has the obvious economic effect.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a rapid transportation method for medium-diameter and long-distance tunnel shield construction. Background technique [0002] The development and utilization of urban underground space has become an important means to increase urban capacity, ease urban traffic, and improve urban environment, as well as an important way to build a resource-saving and environment-friendly city. At present, in the construction of various tunnels such as energy dispatching, water diversion engineering, power communication, and municipal public facilities, the shield tunneling method has been widely used because of its economic rationality and technical advantages under specific conditions. [0003] For the shield construction method, the transportation system, the tunneling system of the shield machine, and the assembly process are three mutually restrictive factors. At present, both at home a...
