The spherical tent is a popular tent in recent years. It is especially popular in European and American countries, and it is also pushed by the tent manufacturers.
The spherical tent literally means a sphere, and the sphere here is usually a hemisphere.
The spherical tents of the tent manufacturers are usually built directly on the ground. As shown in the figure, they can be fixed on cement or mud.
Normally, the ground drying will not be a problem. If it is rainy weather, it is not enough to rely on the moisture-proof pad. To cope with these situations, the spherical hotel tent needs to lay the floor or the stage board on the ground. Of course, the place used to build a spherical tent must be higher than the surrounding area, otherwise the bottom protection should be done well, and the ground will have accumulated water.
