Problems solved by technology
The inner diameter of the underground spherical tank is relatively large. If scaffolding is built inside it during the construction process, it will not only consume a lot of steel pipes, but also if the spherical tank shell bears all the weight of the scaffolding, it will be very unfavorable to control the geometric size of the spherical tank.

Embodiment
[0034] One. First, introduce the supporting device used in the present invention.
[0035] include:
[0036] 1. Central column: set inside the large spherical tank and vertically fixed on the ground, one end is fixed on the prefabricated concrete foundation buried from the ground to the ground by anchor bolts; the central column is a square or cylindrical structure, and the central column can be A truss, the truss is composed of several truss units fixed end to end through flange connection, each truss unit is fixed with a working ladder inside. Each truss unit is fixed with a fixed ring, and each fixed ring is fixed with an annular positioning ring through several radial support arms. The diameters of several annular positioning rings from the top to the bottom of the central column are not equal, and from the top of the central column to the center The diameter of the annular positioning ring at the center of the column increases sequentially; the diameter of the annular po...

The invention relates to a support device of an underground large spherical tank internal platform and an establishment method, which comprise a detachable center stand column, support cantilevers and a ring-shaped positioning ring, wherein the detachable center stand column passes through an internal inclined ladder, the center stand column comprises a plurality of stand column units, the ring-shaped positioning ring is bent through a steel pipe or a shape steel, and flanges are welded on the two ends of the ring-shaped positioning ring, and are connected through bolts. When a spherical tank is assembled, a low pole middle plate is not assembled firstly, and the center stand columns are arranged on a civil foundation which is arranged below a pole middle plate, thereby preventing a tank body from bearing. The center stand column units are assembled through bolts and are equal to the spherical tank in height, each center stand column unit is provided with the support cantilevers along the radial periphery, and ring-shaped positioning rings are arranged on the outer sides of the support cantilevers. One side of a scaffold platform which is arranged in the spherical tank is connected with the positioning rings, and the other side of the scaffold platform is connected with a vertical rod of a scaffold, thereby forming multiple layers of scaffold platforms which are arranged in the spherical tank. The establishment method is suitable for large spherical tanks, and a structure mode comprises a pillar spherical tank and a skirt spherical tank. The support device of the underground large spherical tank internal platform and the establishment method are suitable for spherical tanks which are arranged in an underground space, but are not limited in underground spherical tanks.
Description
technical field [0001] The invention relates to the field of mechanical steel structures, in particular to an internal platform support device and an assembly method of a large underground spherical tank. Background technique [0002] The spherical tank proposed to be built hundreds of meters deep underground in the rocks in the mountains, with a diameter of more than 30,000 mm. The underground cave is a cylindrical space, and the tunnel connected to the ground only reaches the platform operation room next to the top of the cave, which is about several hundred meters above the ground. The inner diameter of the underground spherical tank is relatively large. If a lot of scaffolding is built inside it during the construction process, it will not only consume a lot of steel pipes, but also if the spherical tank shell bears all the weight of the scaffolding, it will be very unfavorable to control the geometric size of the spherical tank.
