The whole groove type connecting piece 6 takes the joint 5 as the center and a plurality of connecting sections with grooves 15 are arranged radially outwards; at the node 5, two sides which are parallel and close to each other between the adjacent polygonal outer frames 3 are taken as a group of members to be connected; the connecting sections are correspondingly arranged according to a plurality of groups of members to be connected at the node 5, and the members to be connected are embedded in the grooves 15 of the corresponding connecting sections;
The frame-type connecting piece 16 is composed of a groove-type part 17 and a strip-type part 18, wherein the groove-type part 17 is provided with an open groove, two groove walls opposite to the open groove are provided with insertion holes 19, two end parts of the strip-type part 18 are provided with elastic plugs 20, and the elastic plugs 20 can be respectively inserted into the insertion holes 19 at two sides; at the node 5, two sides of each adjacent polygonal outer frame 3 in parallel and close proximity are taken as a group of members to be connected, each group of members to be connected is provided with a frame connecting piece 16, the two sides penetrate into the open slot, and the frame connecting piece 16 forms a seal of the open slot by a strip-shaped part 18;
The spring buckle type connecting piece 22 comprises a base 23, a buckle 24 and a clamping bolt 25, wherein the buckle 24 and the clamping bolt 25 are fixedly connected to the base 23, the clamping bolt 25 is abutted against the end part of the buckle 24 by virtue of the elastic force of an elastic part 28 arranged on the base in a natural state to form a closed circular ring structure, the closed circular ring structure can be extruded inwards under the action of external force and separated from the end part of the buckle 24, so that a notch is formed in the circular ring structure, and the closed circular ring structure can be restored by virtue of the elastic resilience of the elastic part 28 when the external force is relieved; the joints 5 connected by the spring buckle type connecting pieces 22 are formed by fixedly installing bases 23 of the spring buckle type connecting pieces 22 at the vertexes of the polygonal outer frames 3, and connecting the vertexes of the polygonal outer frames 3 by means of two closed rings corresponding to the spring buckle type connecting pieces 22.

Wherein, the connecting piece can select one or more of the three structural forms. The size of the modular belt 26 can be set to the maximum according to the carrying capacity of the transport means so as to reduce the construction amount of the later field;

The polygonal outer frame and the module net surface of the polygonal module, the upper plate and the lower plate of the groove type connecting piece, the groove type part, the strip type part and the elastic plug of the frame type connecting piece are all made of high-strength corrosion-resistant materials.
2. The modular polygonal side slope protection device of claim 1, wherein: the groove type connecting piece is formed by detachably connecting an upper plate and a lower plate which are arranged vertically opposite to each other with a space left between the upper plate and the lower plate, an upper extension arm of the upper plate is fixedly connected with a lower extension arm corresponding to the lower plate to form the connecting section, and a space between the upper extension arm and the lower extension arm forms the groove.
3. The modular polygonal side slope protection device of claim 2, wherein: the upper extension arm of the upper plate is symmetrically provided with two rows of reinforcement tooth members along the arm width direction, and a plurality of reinforcement teeth of each row of reinforcement tooth members are arranged at intervals along the arm length direction; the lower extension arm of the lower plate is provided with an adaptive slot corresponding to each reinforcement tooth; the upper extension arm and the lower extension arm are tightly connected by inserting reinforcing teeth into slots right below and screwing the bolt components at the ends of the arms, and the connecting section is formed by the space between two rows of reinforcing tooth components.
