FIELD: construction. SUBSTANCE: in reservoir between the main bottom and an additional vertical wall there is a flat circular element and a thin elastic distributing gasket. Stiffening ribs are welded to an additional vertical wall, normally to its surface, and also to edges of the main and additional bottom. EFFECT: increased reliability and durability of reservoir. 2 dwg
The invention relates to the field of construction, in particular to a supporting structure for tanks, and can be used in the oil refining industry to equip different types of tanks to reduce loss of product and environmental protection. In practice, operation of various types of storage containers for liquid products happen destruction, which lead to leakage, environmental pollution, and in some cases to explosions and fires. Damage and ecology of the area, and the material is very significant. Why leading organizations are developing a number of technical solutions aimed at improving the reliability of tank design and minimize damage in case of failure. Practice shows that the destruction of tanks mainly occurs in welds connecting the thin sheets of elements horizontal bottom with a vertical wall. Here arise the maximum bending (chime) time and, accordingly, the maximum voltage. In addition, as a result of inaccurate mounting of the main wall of the head may be destroyed (cut) seam okrika or the main sheet of the bottom, if okrika missing. Therefore, the reinforcement is subjected to this node. A known design of tanks with volym bottom, with a vertical wall of the shell, roof, main floor, additional bottom, as well as the drainage system of the product. Such constructions are described in American petroleum Institute standard /API 650 appendix I-undertank leak detection and subgrade protection 4. www.techstreed.com/API/standards/API/std_650product_id=1503605)/. In this technical solution, the bottom of the tank consists of two parallel horizontal plates, between which is placed the absorber of sand, fine gravel or similar material (hereinafter called - the geocomposite). In the event of failure resulting product is absorbed by the absorber and does not leach into the environment. Provided by the control system, which indicates the current leakage and allows you to take timely measures to ensure security. In this design it is difficult to combine with the installation of the primary and secondary walls, which leads to additional, not included in the calculation, the stress, reduce the reliability of the structure. Known technical solution tank with geocomposites double bottom comprising a vertical sheet of hull, main plate, protective plate, additional vertical wall and a horizontal annular support sheet, is mounted near the upper end of the additional vertical wall, drainage system and alarm FR is check the main bottom /US No. 5522340, B65D 90/02, 2008.03.18 www.patentgenius.com/patent7344046.html/. This decision and accepted as a prototype, as closest as to the technical essence and the core set of elements. The disadvantage of this technical solution is the high voltage in the seam of the main floor with an additional vertical wall due to its lack of rigidity, which reduces the reliability of the structures and limits its durability. Horizontal ring reference sheet is intended to ensure that the seams of the fastening elements of the main floor and an additional vertical walls was carried out in the lower position. This design is inefficient, since the normal stress from vertical loads will be transmitted by contact elements and shear stresses - the first seam. The second seam performs only minor problems and, practically, only increases the cost and complexity of installation technology design. The objective of the proposed technical solution is the increase in the rigidity of additional vertical wall connecting the horizontal leaves the primary and secondary heads. This will reduce the deformation that occurs under operating loads, including its own weight, and, accordingly, will increase the reliability of the structure. The essence of the invention is the I increase the reliability and durability of the design of the reservoir, as well as the simplification of installation of the structure. The technical result consists in increasing the reliability and durability of the design of the reservoir by increasing the stiffness of the connection node primary and secondary vertical walls, and to reduce the non-uniformity of transmission arising from inaccuracies installation. The technical result is achieved by the fact that the known device of vertical cylindrical tanks with double bottom for storage of liquid products containing the main vertical wall of the housing, a main plate, an additional plate, additional vertical wall, a thin insulating gasket located on the bottom, on top of which are placed geocomposites fill, drainage system and alarm system leaks, further comprises a flat annular element, which is welded to the end surface of the additional vertical walls, ribs and thin elastic junction strip, located between the flat annular element and the main plate. While ribs are welded to the additional vertical wall normal to its surface and to the fringes in increments of not less than twice a height of more vertical walls, and a thin elastic junction strip is made of heat-resistant mA is Arial. Between the main floor and an additional vertical wall mounted flat annular element, is placed on it a thin elastic junction strip. When this thin elastic junction strip should be made of heat-resistant material, which must withstand high temperatures that occur during execution of a welded joint, it may be Teflon or similar material with a thickness of 1-1 .5 mm additional vertical wall, normal to its surface, as well as to the fringes primary and secondary bottoms welded ribs. Due to the involvement of a flat annular element increases the area of load transfer, which reduces occur at the contact voltage. Installation of the ribs increases the rigidity of the additional vertical walls, which increases its resistance. In addition, these ribs provide stability and a flat annular element. Thin elastic junction strip allows you to provide a more uniform transfer of load and to compensate for inaccuracies of the installation. The construction of the reference node is shown in figure 1, figure 2 shows the cross-section. Here the following notation: 1 - the main vertical wall, 2 - main floor, 3 - additional vertical stink is, 4 - additional bottom, 5 - thin insulating gasket (polyethylene or similar material), 6 - geocomposites aggregate (gravel, sand), 7 - flat annular element 8 is thin elastic distribution strip, 9 - ribs. A distinctive feature of the proposed technical solution is that the vertical load from the overlying structures of the tank, snow load in the winter time, additional vertical wall 3 is transmitted through a flat annular element 7 and the thin elastic junction strip 8 and ribs 9 are welded to the additional vertical wall 3 is normal to the surface and to the fringes. The positive effect is that due to the involvement of a flat annular element 7 increases the area of load transfer, which reduces occur at the contact voltage. Installation of reinforcing ribs 9 increases the rigidity of the additional vertical wall 3, which increases its resistance. In addition, these ribs provide stability and a flat annular element 7. Thin elastic junction strip 8 can provide a more uniform transfer of load and to compensate for inaccuracies of the installation. The mounting structures of the tank has no features and is performed in the usual manner. The installation performance is implemented in the following sequence: - preparation of the surface of the base; - laying and welding of sheets for more bottom 4; - installation of additional shells vertical wall 3 with welded flat annular element 7; - filling geocomposites filler 6 on the thin insulating gasket 5, located on the bottom 4; - laying of thin elastic junction strip 8 on the flat annular element 7; - laying and welding of sheets of the main plate 2; - installation of shells a main vertical wall 1; - the welding of additional vertical wall 3 is normal to the surface and to the fringes of the ribs, the step which depends on the size of the tank and is determined by calculation. The proposed solution provides a common operational reliability of the tank, reduces the cost of operation and maintenance in General, due to the simplicity of installation and eliminates the risk of environmental pollution product storage. Metal vertical cylindrical tanks with double bottom for storage of liquid products containing the main vertical wall of the housing, a main plate, an additional plate, additional vertical wall, a thin insulating gasket located on the bottom, on top of which are placed geocomposites filler, si is the subject of drainage and leakage alarm, characterized in that it further comprises a flat annular element, which is welded to the end surface of the additional vertical walls, ribs and thin elastic junction strip, located between the flat annular element and the main plate, and the ribs are welded to the additional vertical wall normal to its surface and to the fringes in increments of not less than twice a height of more vertical walls, and a thin elastic junction strip is made of heat-resistant material.
