The gravity suction anchor includes a suction anchor top plate and a wall of a suction anchor barrel body and uses a concrete press block to reach an estimated set position faster during penetration due to self-weight thereof. Thereafter, the skirt board is lifted to outside of the suction anchor through a lug, and a fixing bolt is used to connect the skirt board to the suction anchor. The spiral anchor rod passes through a skirt board hole performed in the skirt board to penetrate into a deep site of seabed, and concrete is grouted through the skirt board hole to a seabed soil area loosened due to penetration of the spiral anchor rod, thereby forming a concrete reinforced area after the concrete solidifies.

  • Publication number: 20220243107
    Abstract: Provided is a heat transfer composition, which is characterized in that the heat transfer composition comprises the following three components: 1,1,1,2-tetrafluoroethane (R134a) with a mass ratio of 28%-46%, 2,3,3,3-tetrafluoropropene (R1234yf) with a mass ratio of 33%-71%, and trans 1,3,3,3-tetrafluoropropene (R1234ze(E)) with a mass ratio of I %-23%. The described heat transfer composition which replaces R134a not only has the environmentally friendly features of having low GWP and zero ODP, but also has excellent thermal performance. When applied in a centrifugal chiller, the volumetric refrigeration capacity and energy efficiency are equivalent to those of a centrifugal unit using an R134a refrigerant, and the slip in temperature is small; thus, the present application may become a heat transfer composition to replace R134a.
