The present invention provides underground equipment enabling the internal heat of a buried box to be stably discharged to the outside without an external power source. In one embodiment, underground equipment comprises: a buried box of which the top is open; a cover part inserted into the buried box so as to cover the top; and air-conditioning parts which are disposed at the cover part, and which ventilate or close the inner space of the buried box according to the inflow of external water, wherein the inner space of the buried box is closed by means of the lower surface of the cover part, and a heat exchange part for allowing heat to be exchanged between rainwater and the inner space when the rainwater flows therein is disposed at a position of the cover part that differs from the arrangement position of the air-conditioning parts.

A prefabricated substation is provided with a solid state breaker and a transformer. The substation preferably transforms voltage from a medium voltage to a low voltage. The substation also breaks current flow through the substation when a fault occurs. The primary components of the substation, including the transformer and solid state breaker, are located together within the housing.

Proposed is a pull-out type buried underground field monitoring control panel with a flood double safety structure, in which it allows to control in a pull-out type manner by burying a control panel for controlling traffic lights, street lights, or water supply pipes in the ground, protect various types of electronic devices from moisture or water in the ground using a double sealing structure based on an air pocket principle, and have a double safety structure against flooding by generating internal pressure at a dangerous time point and applying the pressure to the water flowing into the inner box to push it out of the inner box although the air pocket function is degraded as an abnormal condition occurs in the structure of a “Π” shape due to long-time flooding.

A system and method for a modular inland pipeline valve control station includes a control valve, a control enclosure, a flow instrument, and a piping spool connected to a pipeline. The modular inland pipeline valve station is transportable and controlled from a central control location. The modular inland pipeline valve station is constructed, assembled, tested, and commissioned with the center control center at a module yard prior to being transported and installed at the pipeline. The modules can be installed slightly offset to the pipeline with drop-out or curved rotatable spools to allow possible access to the pipeline for testing and inspection and for connecting a pig receiver, pig launcher or a bypass.
