Valve arrangement structure of construction machine

A valve arrangement structure of a construction machine, comprising:

• a control valve connected to a hydraulic device via a hydraulic pipe;
• a solenoid valve connected to the control valve via a plurality of pilot pipes;
• a valve supporting member which supports the control valve from below the control valve;
• and
• a supporting bracket which supports the solenoid valve so that the solenoid valve is positioned above the control valve, wherein
• a hydraulic port to which the hydraulic pipe is connected is provided on a lateral connection surface of the control valve, and
• the supporting bracket includes:
• an erected section which is erected at a position separated from the connection surface of the valve supporting member in a horizontal direction so as not to overlap with the connection surface in a viewpoint along a direction perpendicular to the connection surface and which extends in a vertical direction from the valve supporting member to a position higher than an upper surface of the control valve;
• a placing section which extends from an upper end section of the erected section so as to be arranged at a position higher than the upper surface of the control valve and on which the solenoid valve is placed;
• and
• at least one guide section which is provided in the erected section, which holds the pilot pipes in a bundled state so that the pilot pipes are routed in the vertical direction along the erected section, and which restricts the pilot pipes from moving in at least a direction separating from the control valve.
