[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, a temporary protective fence for the renovation of a sewage well includes posts 1 and guardrails 2. The posts 1 are vertically arranged on the ground at intervals, and the guardrails 2 are arranged between two adjacent posts 1.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, dovetail blocks 21 are provided on both ends of the guardrail 2, and grooves 11 for the dovetail blocks 21 to be inserted are provided on both sides of the post 1, as well as dovetail grooves 12 that connect the lower end of the grooves 11 and allow the dovetail blocks 21 to slide into them.

[0027] like Figure 1 , Figure 2 As shown, a pressure rod 13 with a communicating groove 11 is vertically threaded onto the column 1. The pressure rod 13 is used to press the upper end face of the dovetail block 21.

[0028] When a protective fence needs to be erected, the posts 1 are vertically placed on the ground. Then, the dovetail blocks 21 at both ends of the guardrail 2 are inserted into the grooves 11, and the guardrail 2 is controlled to move downwards, causing the dovetail blocks 21 to slide and embed into the dovetail grooves 12, thus achieving lateral limitation. Next, the pressure rod 13 is tightened, pressing the upper surface of the dovetail blocks 21 to achieve vertical limitation, thereby completing the rapid erection of the protective fence and improving construction efficiency.

[0029] like Figure 3 As shown, the guardrail 2 includes support rods 22 and telescopic frames 23. The support rods 22 are spaced apart and each has a roller 24 at its lower end for moving the guardrail 2 on the ground. The telescopic frame 23 is located between two adjacent support rods 22 and includes a telescopic tube 231 and a telescopic rod 232.

[0030] like Figure 3 As shown, the telescopic tube 231 is vertically slidably connected to the support rod 22, and the telescopic rods 232 are in pairs and rotatably connected to each other at their middle positions. The upper end of each pair of telescopic rods 232 is rotatably connected to the telescopic tube 231, and the lower end is rotatably connected to the support rod 22.

[0031] Therefore, by setting up a foldable and retractable guardrail 2, the entire guardrail can be stored and transported in a retractable manner, making the mobile transportation process more convenient and easy to reuse. At the same time, it can be quickly deployed on the ground for construction, improving construction efficiency.

[0032] like Figure 2As shown, a mounting tube 3 is rotatably connected to the side wall of the column 1, and a mounting rod 31 is vertically and slidably connected inside the mounting tube 3. A flexible insertion rod 32 is horizontally and slidably connected inside the mounting rod 31. A row of insertion holes 33 for the insertion rod 32 is provided on the outer wall of the mounting tube 3, and a mounting plate 34 for contacting the ground is provided at the lower end of the mounting rod 31.

[0033] When the post 1 is installed on the ground, the control installation tube 3 is flipped outward, and then the insertion rod 32 is pressed into the installation rod 31. The control installation rod 31 is then slid outward, and finally the installation plate 34 is flipped to touch the ground, so that the insertion rod 32 is inserted into the corresponding insertion hole 33. Then the installation plate 34 is fixed on the ground, forming a diagonal bracing structure on the post 1, which increases the stability of the entire protective fence during operation.

[0034] like Figure 1 , Figure 4 As shown, locking rings 14 are provided on both sides of the column 1, and a warning banner 4 is provided between two adjacent columns 1. Both ends of the warning banner 4 are provided with locking hooks 41 to hook the locking rings 14. A storage slot 15 for inserting the warning banner 4 is vertically provided on the column 1.

[0035] When it is necessary to install the warning banner 4, take the warning banner 4 out of the storage slot 15, unfold the warning banner 4, hook the locking hook 41 on the warning banner 4 onto the locking ring 14 on the column 1, so that the warning banner 4 can be unfolded and used to warn people.

[0036] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
