Project Challenges: Double Impact of Typhoons and Earthquakes The coal storage bunker of Power Plant in the Philippines has been facing tests from extreme natural conditions since the planning stage: Climate Challenge : Located in a super typhoon zone with wind speeds of up to 260 kilometers per hour, it withstands fierce storms and heavy rains every year. Geological Threat : Situated in a high seismic intensity zone with Z=0.4, the structural stability must be absolutely guaranteed. Cost Pressure : The client requires strict control over overseas construction costs while ensuring safety, and also demands controllable construction periods. Ultra-Large Scale : With a total height of 48.675 meters and a foundation height of 3.0 meters, the long-span dome design poses a great challenge to structural strength for industrial projects. Solutions: Comprehensive Upgrades from Design to Materials Targeting these pain points, our overseas engineering team has tailor-made a combined solu...

 Comparison of welded and bolted ball netting structures

space frame


Analysis in terms of quality assurance.

1, welded ball structure using hollow ball (material Q235 ordinary steel) and welded pipe on the site of the welding, by the temperature and wind speed, under the influence of the welding machine equipment and basic artificial manual, resulting in the material, positioning, welding process, error, low precision. The steel has stress deformation before and after welding, which is a safety hazard. The angle control between the various bars is not accurate after use, which can easily distort the bars and destroy the balance of force transmission. It is not possible to adapt to the requirements of shaped curves and oversized spans, and the quality is difficult to guarantee, so there are great limitations.

2、Bolt ball structure is made of solid ball (material 45# high strength steel) and high strength bolt (material 40Cr), which are closely jointed. The angle between the screw holes on the bolt ball is precise, and the bar has built-in 10.9S high-strength bolts, which are tensile and compressive, and the force transmission is stable and balanced.

What is a coal bunker?

-

Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

 It is widely used in modernist architecture. Steel structure installation is mainly carried out by electric welding welding and bolts. Because the steel frame structure is compact and practical, it brings great convenience to engineering construction. In order to promote the sustainable development concept of steel frame structure in the construction engineering industry, it is necessary to carry out an in-depth analysis of the construction stage of steel structure, especially the node design, to ensure reliability.       Steel plate materials are widely used in modernist buildings because of their extreme seismic performance, plasticity and reliability. Jiangsu steel structure project construction is to be processed with bolts or steel to make the building structure. Accompanied by the improvement of living standards and the rapid development of the construction industry, the requirements for steel frame structure are rigorous. As a result, the design of steel fra...
