Description

Technical Field

[0001] The utility model belongs to the field of petrochemical engineering, and particularly relates to a flare tower foundation with a frame structure. Background Art

[0002] An elevated flare is one of the iconic structures in petrochemical enterprises. It is a special facility in petrochemical plants for burning and treating waste gas and toxic gas. It usually consists of an automatic control system, an ignition system and a flare cylinder, which can make the flame burn at a high altitude far from the ground, thus protecting the personnel on the ground and the factory equipment. A flare tower is a common high-rise structure in petrochemical plants, which is used to support the flare cylinder and ensure its stability. Generally, a flare tower is composed of multiple flare tower columns. The flare tower not only has to support the weight of the flare cylinder, but also needs to bear the influence of natural actions such as wind load and earthquake. The foundation of the flare tower is the key part to ensure the stability and safety of the flare tower. At present, generally, the foundation of the flare tower is set at the ground level, and the common foundation forms include: reinforced concrete independent foundation, pile raft foundation, etc. The corresponding design ideas and construction schemes are relatively simple and conventional.

[0003] In order to strictly control the building safety distance and improve the site utilization rate in the plant layout of petrochemical enterprises, the exhaust stack and the elevated flare are usually arranged in a position far from the core area or in a marginal area that is difficult to utilize. The common foundation forms (such as reinforced concrete independent foundation, pile raft foundation, etc.) are all large monolithic concrete foundations, and the ground height at the foundation is usually within 1m. The application scenario is limited to setting the foundation elevation of the flare tower at the ground elevation. When the construction site has complex terrain and large height differences, the conventional foundation forms cannot meet the actual use requirements according to local conditions. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides a flare tower foundation with a frame structure, which uses a frame structure support to adjust the elevation of the flare tower foundation, so as to break through the terrain limitation in the process layout and reasonably optimize the plant layout.

[0011] Furthermore, secondary beams or floor slabs for arranging the foundation of the torch auxiliary equipment are connected between the second frame beams at the top layer.

[0012] Furthermore, the cross-sectional area of ​​the flare tower column foundation is larger than the cross-sectional area of ​​the second frame column, so that the flare tower column foundation meets the structural requirements of the flare tower column foot, and a first shear groove is reserved at the top of the flare tower column foundation for inserting the flare tower column foot. After the flare tower column foot is installed in the first shear groove, secondary grouting is performed to form a secondary grouting layer after the grouting is completed.

[0013] Furthermore, a plurality of first anchor bolts are pre-embedded inside the flare tower column foundation outside the first shear groove, and the plurality of first anchor bolts are evenly distributed around the circumference of the first shear groove.
