ト装置。[Scope of Claim for Utility Model Registration] 1. A chamber is formed between the bulk head of the shield hull and the cutter wheel, and a screw conveyor for earth and sand discharge, a shield jack, etc. are arranged in the shield hull behind the bulk head, and A shield in which the excavated earth and sand taken into the chamber is taken out from an earth and sand outlet provided at the bottom of the bulkhead and discharged by a screw conveyor, and the earth and sand outlet is opened and closed by a gate device consisting of a gate and a gate operating jack. In the excavator, the gate and the gate operating jack are arranged on the chamber side of the bulkhead, and a bulkhead is provided on the front side of the bulkhead to separate the gate operating jack from the chamber, and when the gate is moved to a position where the earth and sand extraction port is opened. A gate device for a chamber in a shield excavator, characterized in that the gate is configured to be housed in a space between the partition wall and the bulkhead. 2. Utility model registration claim 1, characterized in that the bulkhead is composed of a double wall, and the wall located on the chamber side forms the partition wall.
A gate device for a chamber in a shield tunneling machine as described in 2.
