Description

Sealing plug structure of underground water seal stone cave oil depot Technical Field The utility model relates to the technical field of underground water seal cave depot construction, in particular to a sealing plug structure of an underground water seal cave depot. Background The underground water-sealed petroleum cave depot is a cave with a certain shape and volume, which is formed by artificial excavation in a rock mass below the ground water level, and is used for storing petroleum and other products. The oil storage cavern of the underground water seal oil cavern is communicated with the ground during construction through the first connecting roadway, the vertical shaft and the second connecting roadway, each oil storage cavern is isolated by the sealing plugs after construction is completed, and meanwhile, the oil inlet vertical shaft and the oil outlet vertical shaft are sealed by the sealing plugs to form independent airtight storage spaces. Therefore, the sealing plug in the underground water-sealed petroleum cave depot plays an important role in isolating the cave depot from the external environment. The utility model patent number CN206205934U discloses a sealing plug of an underground water seal petroleum cave depot roadway, which comprises a sealing plug body, wherein the sealing plug body is embedded in a rock mass between a first connecting roadway and a second connecting roadway, the sealing plug body is of a round table type structure, at least six filling grouting pipes and four exhaust pipes are arranged on the vault of the sealing plug body, at least fifteen contact grouting pipes are arranged on the periphery of the sealing plug body, a grouting stop plug is arranged on the filling grouting pipes, the exhaust pipes and the contact grouting pipes penetrate through the contact surface of concrete and surrounding rock by at least 10cm, the sealing plug is of a reinforced concrete sealing plug of a round table type structure, the pressure between different cave tanks can be borne, the contact positions of the rock mass can not leak through the arrangement of the filling grouting pipes, the exhaust pipes and the contact grouting pipes, and the isolation of a storage oil cave is realized, in the patent, the sealing plug is of a round table type structure, more excavation quantity is needed, further rock mass stress loss is caused, the construction time and cost are increased, the concrete is easy to produce in the concrete pouring process, the concrete is greatly heated, and the concrete strength is greatly reduced, and the concrete is easy to hydrate.
