ことを特徴とする水圧検出装置。[Scope of claim for utility model registration] 1. Installed on the shield body of a shield excavator,
This is a device that measures the water pressure of groundwater on the face side by capturing water between excavated soil particles and detecting the pressure of this water. A housing that is attached to a shield body with a porous surface having many small holes and a shielded space formed on the back side of the porous surface, and a housing that is attached to the housing to detect the pressure of groundwater flowing into the shielded space. A water pressure detection device comprising a water pressure detector and a drain pipe connected to the housing to create a flow of water within the shielded space. 2 Utility Model Registration Scope of Claim 1 The water pressure detection device according to claim 1, characterized in that the housing is connected to a water pipe that sends wash water into the shielded space. 3. Utility Model Registration Claim 1: The water pressure detection device according to claim 1, wherein the housing is slidably provided with a cleaning rod for breaking up particles accumulated in the shielded space.
