Description

Auxiliary device with soil material removing function for air shaft of shield tunneling machine

Technical Field

The invention relates to the technical field of tunnel excavation, in particular to an auxiliary device with a soil material removing function for a shield machine air shaft.

Background

A shield machine is a tunnel boring machine using a shield method. The shield construction method is a "shield" (referred to as a supporting segment) for constructing (laying) a tunnel while a heading machine is heading, and is different from an open construction method. Internationally, generalized shield machines can also be used in rock formations, as distinguished only from open (non-shield) tunnel boring machines. In China, the tunnel boring machine used for the soft soil stratum is customarily called a (narrow sense) shield machine, and the tunnel boring machine used for the rock stratum is called a (narrow sense) TBM. The (full-face) tunnel boring machine adopts a shield method in one part and an open construction method in the other part, for example, the full-face double-shield rock Tunnel Boring Machine (TBM) which is independently developed by Chinese iron construction and heavy industry is provided with double shields, does not need to construct (lay) the shield of the tunnel, namely does not need to lay a segment, integrates excavation, support and slag tapping, and can realize one-step forming of the tunnel. The basic working principle of the shield tunneling machine is that a cylindrical steel component is pushed forwards along the axis of the tunnel to excavate soil. The casing of the cylinder assembly, the shield, acts as a temporary support for the excavated, not yet lined tunnel section, bearing the pressure of the surrounding soil layers and sometimes also the groundwater pressure and the water that is trapped outside. The operations of digging, dumping, lining and the like are carried out under the shield of the shield.

In consideration of safe ventilation, a plurality of middle air shafts are often arranged along a tunnel, when a shield machine passes through the air shafts, a large amount of soil materials enter the air shafts from an outlet, the soil materials are sometimes too large in volume and also contain a large amount of hard soil blocks and stones, the soil materials influence construction in the air shafts, and the soil materials are too large in volume, hard and difficult to manually process, so that the soil materials are inconvenient to cushion in the air shafts; and when shield structure machine worked and passed through the air shaft, often can take advantage of the machine to shield structure machine each position maintain and overhaul, to some eminence positions that are not convenient for to contact, operating personnel often can set up the ladder and go to overhaul and maintain, the ladder is not only inconvenient but also not enough to maintenance personal's safety guarantee degree to also restricted operating personnel's operation action to a certain extent.
