The invention provides a modular heliostat surface shape rapid assembling platform, the assembling platform is composed of a movable reference platform, a transmission branch chain and a fixed base, the movable reference platform is connected with the fixed base through the transmission branch chain, the movable reference platform is composed of a platform support, a mounting flat plate and a pneumatic positioning device, and the platform support is connected with the mounting flat plate through the transmission branch chain. The platform support is composed of an outer ring support, an inner ring support and a communicating support, the plane geometric center points of the inner ring support and the outer ring support coincide, the geometric center points are the center of the movable reference platform, the center line of the plane of the communicating support coincides with the center of the movable reference platform, and the included angle between the center line of the plane of the communicating support and the center line of the plane of the communicating support is 120 degrees. Mounting plates are arranged on the end face of the communicating support, and the mounting plates are distributed in an equilateral triangle shape. Compared with the prior art, the method does not need a complex process of measuring single planar sub-mirrors one by one and calculating a positioning reference, can carry out the flexible combination of sub-positioning platforms, is suitable for the surface shape assembly of various types of heliostats, improves the universality of assembly equipment, and effectively reduces the manufacturing, transportation and maintenance cost of the whole equipment. The method is not influenced by external conditions such as climate or illumination, has the characteristics of no error accumulation, and can realize high-precision motion control.

This utility model discloses an embedded lightweight soil retaining panel structure, installed on a base with mounting grooves. The lightweight soil retaining panel structure includes precast panels and mounting beams arranged in an H-shape at intervals. The top of each precast panel has a groove, and the bottom of the precast panel has a retaining edge that matches the groove. The mounting beams are spaced apart on the base, and the retaining edges of the precast panels at the bottom mate with the mounting grooves. Both ends of the precast panels are engaged with the mounting beams, and the upper precast panels are interconnected through the retaining edges and grooves. This embedded lightweight soil retaining panel structure, with its H-shaped mounting grooves on the base and mounting beams on both sides, fixes the mounting beams to the base, thus limiting the lateral movement of the precast panels. Simultaneously, the retaining edges and grooves on the precast panels allow for rapid splicing of the precast panels.
