[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model, so as to have a further understanding of the conception of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought by the utility model.

[0026] As shown in Figure 1 and Figure 2 The utility model discloses a construction protective fence for constructional engineering, which comprises a plurality of unit structures arranged side by side, and the unit structure comprises:

[0027] The base 1 is provided with a vertical telescopic sleeve on the left and right sides thereof.

[0028] The vertical telescopic sleeve comprises a plurality of hollow cylinders 2, the inner diameter of the hollow cylinder 2 is negatively correlated with the height of the hollow cylinder 2, and the plurality of cylinders are sequentially and movably sleeved according to the size of the inner diameter; the top side wall of each hollow cylinder 2 is provided with a first bolt hole 3, and the bottom side wall is provided with a second bolt hole 4; the outer hollow cylinder 2 and the adjacent inner hollow cylinder 2 are locked by a bolt penetrating through the first bolt hole 3 and the second bolt hole 4; and the top outer wall of each hollow cylinder 2 is fixedly provided with a connecting collar 5.

[0029] The barrier net 6 is provided with a pull rope on the left and right sides of the top thereof and is fixedly connected with the connecting collar 5 through the pull rope.

[0030] The top plate 7 is arranged on the top of the vertical telescopic sleeve and is fixedly connected with the top of the innermost hollow cylinder 2.

[0031] The main working principle of the device is as follows: the base 1 is arranged at the installation point of the guardrail, and provides sufficient support for the entire guardrail. The vertical telescopic sleeve is arranged on the upper surface of the two sides of the base 1, and is used as the main structure for adjusting the height of the guardrail. The vertical telescopic sleeve comprises a plurality of hollow cylinders 2 which are movably sleeved with each other. In an embodiment, the hollow cylinders 2 are distributed in a manner that the inner part is high and the outer part is low, and the inner part is small and the outer part is large. A sleeve ring 5 is fixedly connected to the top outer wall of each hollow cylinder 2, and is used to connect a net 6, so as to reduce the self-weight of the guardrail. At the same time, when the guard net is in the storage state, the entire vertical telescopic sleeve forms a conical body which is gradually contracted from bottom to top, so as to avoid the mutual influence of the nets outside the hollow cylinders 2. In order to reduce the mutual interference between the nets 6 during storage, each net 6 can also be pre-stored in a rolled-up manner. When it is necessary to raise the overall height of the guardrail, the height of the hollow cylinders 2 is sequentially pulled in the order of inside to outside, and the second bolt hole 4 at the bottom of the inner layer hollow cylinder 2 is aligned with the first bolt hole 3 at the top of the adjacent outer layer hollow cylinder 2, and then a bolt is inserted in the direction of the two bolt holes to lock the height. The top plate 7 plays a role in strengthening the protection and balancing the overall stress of the device during the entire process.

[0032] As a preferred embodiment, the end faces of the top plate 7 are provided with connecting holes 8 in the axial direction, the side walls of the two ends of the top plate 7 are provided with positioning holes 9, the connecting holes 8 and the positioning holes 9 are communicated and perpendicular, and a connecting rod 10 is inserted into the connecting holes 8 of the adjacent faces of the two unit structures.

[0033] The embodiment provides a specific connection mode between the top plates 7, which is used for strengthening the connection relationship between the adjacent unit structures. Figure 3 and Figure 4 As shown in the drawings, the connecting holes 8 are arranged on the end faces of the top plate 7, and the connecting rod 10 is inserted into the connecting holes 8. The spring impact bead 11 on the connecting rod 10 mainly comprises a spring which is perpendicular to the connecting rod 10 in the axial direction, the spring is fixedly connected with a vertical connecting plate 101 which is vertically arranged in the connecting rod 10, and the other end of the spring is fixedly connected with a steel column or a steel bead. During the process that the connecting rod 10 is inserted into the connecting hole 8, the steel column or the steel bead is pressed by the hole wall of the connecting hole 8, so that the spring is compressed. When the steel bead or the steel column moves to the positioning hole 9, the spring loses the compression force and rebounds, so as to be clamped into the positioning hole 9, and the overall fixing of the connecting rod 10 is realized, so that the adjacent unit structures can be firmly and stably connected as a whole. In order to ensure the stability of the spring impact bead 11, two spring impact beads 11 can be symmetrically arranged on the two sides of the connecting plate 101.

[0034] As a preferred embodiment, the top plate 7 upper surface is further provided with an installation slot 12 along the axial direction of the top plate 7, and a water delivery pipe 13 is placed in the installation slot 12, and the lateral wall of the water delivery pipe 13 is provided with a plurality of horizontal atomizing nozzles 14.

[0035] In the embodiment, as shown in Figure 3 , the installation slot 12 on the top plate 7 is mainly used for placing the water delivery pipe 13, and the lateral atomizing nozzles 14 on the water delivery pipe 13 can achieve the function of spraying water mist, so as to reduce the dust during construction, thereby avoiding the need for additional spray mechanism.

[0036] As a further embodiment, a plurality of branch holes 15 are further provided through the lateral wall of the installation slot 12, and the water delivery pipe 13 is provided with a plurality of branch pipes 16 penetrating the branch holes 15, and the atomizing nozzles 14 are arranged at the end of the branch pipes 16.

[0037] In the embodiment, as shown in Figure 3 , the branch holes 15 are arranged on the lateral wall of the installation slot 12, which are used for fixing the branch pipes 16 on the water delivery pipe 13, thereby fixing the axial position of the water delivery pipe 13, and also reducing the blockage of the water mist sprayed by the atomizing nozzles 14 to the slot wall of the installation slot 12, effectively avoiding water accumulation in the installation slot 12.

[0038] As a further embodiment, the top plate 7 upper surface is further hinged with a cover plate 17, and the cover plate 17 is arranged on the top plate 7 after being turned over.

[0039] In the embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the top plate 7 is provided with a reversible cover plate 17, which is arranged on the installation slot 12 on the top plate 7, so as to effectively reduce the influence of the external construction environment on the water delivery pipe 13, and avoid the damage of the water delivery pipe 13 caused by flying stones during external construction.

[0040] As a further embodiment, the cover plate 17 and the vertical surface away from the hinge point on one side of the top plate 7 are provided with a lock head and a lock catch matched with each other.

[0041] In the embodiment, after the cover plate 17 and the top plate 7 are connected, the lock head and the lock catch are locked, so as to avoid the cover plate 7 from being bounced away due to external vibration, and effectively ensure the protection stability of the cover plate 17.

[0042] As a further embodiment, the bottom surface of the base 1 is provided with a tooth-shaped anti-skid pattern 18.

[0043] In the embodiment, the anti-skid teeth 18 are arranged on the lower surface of the base 1 to increase the friction between the base 1 and the ground, so that the base 1 does not slip during use of the guardrail.
