Description

Concrete base encloses fender Technical Field The utility model relates to the field of fences, in particular to a concrete base fence. Background In modern construction sites and municipal works, the fence serves as an important safety protection facility and plays a key role in isolating construction areas and guaranteeing pedestrian safety. At present, the common concrete base is provided with a metal enclosure structure, but the potential safety hazard of the metal enclosure structure is not ignored. Taking the movable enclosure of the base disclosed in patent CN2022200822400 as an example, after the enclosure is fixed by using a transverse fastener, a protruding portion is inevitably formed on the inclined surface of the base. The design defect is hidden with great risk in actual use, and when pedestrians or vehicles collide with the fence carelessly, the protruding parts act like sharp edges, so that the damage degree to collision objects can be obviously increased, and public safety is greatly threatened. Disclosure of utility model In view of the foregoing, it is an object of the present utility model to provide a concrete foundation enclosure, which solves the problems of the prior art. The concrete base enclosure comprises a concrete base, an enclosure and a backstop, wherein the top surface of the concrete base is provided with an enclosure slot, the cross section of the enclosure slot is trapezoidal, the enclosure is inserted into the enclosure socket and is increased along with the increase of the insertion depth, the friction force between the enclosure and the enclosure slot is gradually increased to realize the self-locking of the enclosure, a T-shaped groove is arranged beside the enclosure slot, a bolt is clamped in the T-shaped groove, and the backstop is fixed through the bolt and is propped against the back surface of the enclosure. Further, inclined surfaces are arranged on the front side and the rear side of the concrete base, at least one of the inclined surfaces on the two sides is a sectional inclined surface, and the angle of the upper section inclined surface of the sectional inclined surface is smaller than that of the lower section inclined surface. Further, the bottom of the concrete base is provided with at least two grooves. Further, at least two hanging holes are arranged on the side face of the upper portion of the concrete base. Furthermore, a metal threaded pipe is embedded in the hanging hole, and the metal threaded pipe is connected with a hanging ring. Further, a drain hole is reserved in the concrete base, and the drain hole leads to the enclosure slot. Advantageous effects Firstly, the surrounding baffle slot adopts a trapezoid design with a large upper part and a small lower part, so that the surrounding baffle is self-locked, and then is matched with a back support for fastening, so that an additional protruding transverse fastener is avoided, and the injury risk caused by protruding parts during collision is eliminated; Secondly, the inclined plane and the sectional inclined plane of the concrete base are designed to enable the gravity center to be closer to the center of the base, so that the material use is reduced, the cost is lowered, the stability of resisting external force impact is improved, and the public safety is further ensured; Thirdly, the bottom groove, the upper hanging hole and other designs are convenient for carrying by a forklift and hanging equipment, so that the construction convenience is improved, and the hanging rings can be detached after being used, so that the bases can be closely arranged to form an isolation net, and the whole appearance and practicability of the enclosure are ensured; fourth, the setting of wash port avoids enclosing fender slot ponding and stinks, has optimized enclosing fender service environment. Drawings Fig. 1 and fig. 2 are schematic perspective views of the present application at different viewing angles; FIG. 3 is a schematic view of the assembly of the back support; FIG. 4 is an enlarged view of FIG. 3 at A; FIG. 5 is an assembly schematic of a bail; The concrete foundation is characterized by comprising a concrete foundation 1, a fence slot 101, a T-shaped slot 102, a segmented inclined plane 103, a groove 104, a hanging hole 105, a water drain hole 106, a fence 2, a backstop 3, a bolt 4, a metal threaded pipe 5 and a hanging ring 6.
