[0013] The technical solution of the present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0014] Example:

[0015] This embodiment provides a prefabricated foundation for a communication tower, such as Figure 1 and Figure 2 As shown, it includes a raft plate 2, a panel 1 and a basic body 3 formed by splicing a plurality of splicing blocks 10. The panel 1 is arranged around the raft plate 2. A boss 4 is provided in the center of the raft plate 2. A plurality of screws 6 are screwed on the boss. The splicing blocks 10 are sleeved on the screws to form the basic body.

[0016] The splicing block 10 is provided with a plurality of first through holes 12 that match the screw 6, and the splicing block 10 is sleeved on the screw through the first through holes 12. The upper end surface of the boss 4 and the upper end surface of the splicing block 10 are provided with a plurality of limiting grooves 9, and the lower end surface of the splicing block 10 is provided with a plurality of limiting protrusions 11. The limiting grooves 9 match the limiting protrusions 11, and the splicing block 10 is directly spliced ​​and limited by the limiting protrusions 11 and the limiting grooves 9. A pressure plate 13 is also provided on the base body 3. The pressure plate 13 is provided with a plurality of second through holes 13 that match the screw, and a plurality of limiting protrusions are provided on the lower end surface of the pressure plate. The pressure plate is sleeved on the screw and its lower end surface is buckled with the upper end surface of the base body. A locking nut 7 is provided on the screw to fix the pressure plate to the base body.

[0017] A plurality of grounding bodies 8 are provided on the lower end surface of the raft plate 3 , and a conductive mesh is built into the raft plate. The conductive mesh is respectively connected to the grounding bodies 8 and screwing seats in the boss 4 for screwing.

[0018] The communication tower prefabricated foundation in the embodiment is divided into two parts, wherein the raft, the coaming and the boss are an integral whole as the first part, and the foundation body is the second part. The two parts can be transported separately and then assembled. In the assembly, the first part is placed first, the screw rod with a proper length is selected according to the requirement and screwed on the boss, then the required number of splicing blocks are strung on the screw rod, and preferably the pressing plate is covered to lock, so that the assembly of the communication tower prefabricated foundation is completed.

[0019] The specific embodiments described herein are merely illustrative of the principles of this application. Numerous modifications or adaptations will be readily apparent to those skilled in the art of this application without departing from the spirit or scope of the application as defined by the following claims.
