- the present invention relates to a ground liquefied natural gas storage tank and a method of manufacturing the same.
- a liquefied natural gas storage tank is for storing or transporting a cryogenic liquefied natural gas (Liquefied Natural Gas (LNG)) of about -165 °C, the land-type storage tank (installed on the ground or buried underground) Ground storage tanks, buried storage tanks, semi-filled storage tanks), and mobile storage tanks installed in vehicles, ships, and other means of transportation.
- LNG cryogenic liquefied Natural Gas
- the liquefied natural gas storage tank stores the liquefied natural gas in a cryogenic state, there is a risk of explosion when exposed to impact.
- the structure of liquefied natural gas storage tank should satisfy the conditions such as impact resistance and sealability.
- the LNG storage tank has a multilayer wall structure. That is, the liquefied natural gas storage tank has a tank wall (outer tank) in which a storage space is formed, an inner tank (inner tank) that directly contacts the liquefied natural gas and seals the liquefied natural gas, and is interposed between the tank wall and the inner tank to liquefied natural gas. Perlite to insulate the.
- the ground storage tank included in the land-type storage tank can be generally constructed as follows.
- the side wall construction can be achieved by injecting concrete into the formwork, and then removing the formwork when the concrete is hardened. Then, the inner wall and bottom of the side wall are reinforced with insulation panels, the inner tank is constructed inside the concrete, and the inner tank is finished.
- the present invention was created to solve the problems of the prior art as described above, an object of the present invention, while using the sandwich concrete during the construction of the ground storage tank, while improving the insulation performance, impact resistance, durability, construction is easy and construction It is to provide a ground liquefied natural gas storage tank capable of reducing the period and a method of manufacturing the same.
- an object of the present invention by adding an external reinforcing material to the outer tank using the sandwich concrete, while improving the heat insulation performance, impact resistance, durability, while reducing the weight can be modularized manufacturing, thereby reducing the construction cost To provide a ground liquefied natural gas storage tank and a method of manufacturing the same.
- the above-mentioned liquefied natural gas storage tank and the method of manufacturing the same can be realized by modularizing the outer tank tank and the production place and installation place can be realized, the air shortening of the tank construction, reduction of the required labor force, etc. It is to provide.
- the above-described liquefied natural gas storage tank includes a stand-alone tank having a space formed therein so as to store stored matter; At least one sandwich plate made of a pair facing each other and having a steel plate having a reinforcement formed therein and concrete filled between the steel plates, the outer plate surrounding the independent tank to form an outer tub; And an external reinforcing material formed on an outer surface of the sandwich plate.
- the stand-alone tank is positioned on top of the insulation structure installed on the ground in the state of completion of the production, the modular sandwich plate may be installed after being transported to surround the outer surface of the stand-alone tank is completed.
- the stand-alone tank may include a support portion formed to extend outward from the bottom surface at the lower edge.
- the stand-alone tank may include a support formed to the outside of the surface connected to the heat insulating structure.
- it may further include an outer shell slab covering the lower portion of the sandwich plate to form an outer shell with the sandwich plate.
- the outer shell slab may further include an outer shell slab reinforcement formed in the skeleton.
- it may further include at least one support for supporting the outer shell slab from the ground.
- the support may be a rod, H-beam, pipe or pile as an elevated type support.
- the support is spaced apart from each other, and the length of the support column facing the outermost support column and the outermost support column of the support spaced apart from each other may be equal to or greater than the left and right length of the transport means.
- it may further include a pump tower installed in the stand-alone tank, the pump tower for discharging the storage from the bottom surface of the stand-alone tank.
- the independent tank may be rectangular or cylindrical.
- it may further include a perlite (perlite) provided between the independent tank and the sandwich plate.
- a perlite perlite
- the method for manufacturing a terrestrial liquefied natural gas storage tank according to an aspect of the present invention, the step of installing a support extending to the upper surface; Installing an outer tub slab on the support; Installing an inner tank in the outer slab; And installing a sandwich plate to surround the inner tank along the circumferential surface of the outer slab, wherein the sandwich plate includes an outer reinforcement formed on an outer surface thereof.
- manufacturing the inner tank Modularizing the sandwich plate; Transferring the inner tank to an installation site; And transferring the sandwich plate to an installation site.
- the step of installing the inner tank may further include the step of transferring the inner tank tank to the upper portion of the outer tank slab using a transfer means.
- the conveying means or the other conveying means may move along the outer side of the outer slab to convey the inner tank to the upper portion of the outer slab.
- the step of installing the outer shell slab the step of transferring the outer shell slab to the support; And assembling the outer slab.
- the step of installing the sandwich plate the step of transferring the sandwich plate to the outer slab; And assembling the sandwich plate.
- the method may further include installing perlite between the inner tank and the sandwich plate.
- the step of manufacturing the sandwich plate forming a steel plate which is made of a pair facing each other, the reinforcement is formed; And filling the concrete between the steel plates.
- Ground liquefied natural gas storage tank and a method of manufacturing the same according to the present invention can be installed by modularizing the sandwich plate without the need to install and release a separate formwork, cost savings by reducing the number of installation labor, labor required This can be achieved, and the air shortening can be achieved, so that it is easy to install even in extreme regions such as polar regions and regions with a weak supply of manpower.
- the modular construction method can be performed efficiently and at the same time reduce the material cost Therefore, the construction cost can also be reduced.
- the thickness of the sandwich plate can be made thin, so that the installation of holes for discharging the storage to the outside becomes simple and easy.

- the method of manufacturing the storage tank is divided into a ground type and a ground type branch, where the ground type puts a pile on the ground and forms an outer tank (not shown) by using a formwork (not shown). Insulation is made by installing insulation, and the underground type is dug the ground to a certain depth, installs an outer tank (not shown), and manufactures an inner tank (not shown) with insulation therein.
- a sandwich plate 102 forming an outer tank with an inner tank 200 in order to shorten a time required in a space in which a tank should be installed in the related art.
- the inner tank tank 200 is placed in the installation place, and then completed the above-described liquefied natural gas storage tanks (1, 2) by assembling the sandwich plate (102) module on the outer surface of the inner tank (200). Therefore, the man-hour of installation at the installation place can be reduced.
- the above-mentioned liquefied natural gas storage tanks 1 and 2 according to the first and second embodiments of the present invention are modularized by sandwich plate 102 without the need to install and release a separate formwork (not shown). Since construction can be carried out, installation man-hours are reduced, labor costs are reduced, and air shortening can be achieved, making it easy to install even in harsh regions such as polar regions and areas where labor supply is weak.
- the weight can be significantly reduced, thereby performing the modular construction method efficiently. At the same time, it is possible to reduce construction costs by reducing material costs.
