[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0026] Reference Figure 1 As shown, the foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane dimensions; in the process of municipal road construction, in order to ensure the safety of the environment around the foundation pit, it is necessary to adopt support, reinforcement and protection measures for the side walls of the foundation pit and the surrounding environment. When the existing columns for installing protective nets or guardrails are fixed to the ground outside the foundation pit, most of them require construction workers to pre-drill at least four fixing holes on the ground, and then drive expansion screws into the fixing holes, and then fix the columns to the expansion screws through nuts. When the foundation pit construction is completed, the protective net or guardrail needs to be dismantled. At this time, the construction workers need to remove the multiple nuts or expansion screws under the columns to realize the removal of the protective net. Since the expansion screws are exposed to the outside when connected with the nuts, it is easy to cause the nuts to rust on the expansion screws in rainy weather, which makes it difficult to remove the nuts, thereby affecting the removal efficiency of the protective net or guardrail. At the same time, the adjustment effect of the protective device is not good. In order to solve this problem, a municipal road foundation pit safety protection device is proposed, including a protection frame 1, the protection frame 1 includes a mounting base 11 and a support frame 12 and a plurality of protection rods 13;

[0027] The mounting base 11 is used to be installed outside the municipal road foundation pit, and the bottom of the mounting base 11 is provided with an adsorption member 2 for adsorbing the road surface;

[0028] The support frame 12 is arranged on the top surface of the mounting base 11 and is arranged vertically with the plurality of protection rods 13, and an adjusting member 3 for adjusting the setting height of the support frame 12 is arranged inside the support frame 12;

[0029] The plurality of protection rods 13 are arranged in an upper and lower interval distribution, and a guide slot 131 is opened in the protection rod 13, and an extension lever for extending the length of the protection rod 13 is horizontally slidably arranged in the guide slot 131; by installing the base 11 and the support frame 12 in the protection frame 1 and setting a plurality of protection rods 13, the purpose of orderly protection of the municipal road foundation pit can be achieved, and by setting the adsorption part 2, the whole protection frame 1 can be stably adsorbed on the surface of the municipal road, avoiding the problem of subsequent removal difficulties caused by punching, and by setting the extension lever and the guide slot 131, the purpose of adjusting the length of the protection rod 13 can be achieved, thereby ensuring the purpose of effective protection on the outside of foundation pits of different sizes.

[0030] It should be noted that when installing the protective frame 1, the installation base 11 is first placed around the outside of the municipal road pit. When the installation base 11 is set on the periphery of the municipal road pit, the installation base 11 is gradually moved closer to the outside of the pit. At this time, the adsorption component 2 is in contact with the ground, thereby achieving the purpose of adsorbing the installation base 11 on the ground.

[0031] Furthermore, the specific structure of the above-mentioned adsorption component 2 is: the adsorption component 2 includes a plurality of adsorption discs 21 arranged at the bottom of the mounting base 11 for low-pressure adsorption with the municipal road; the arrangement of a plurality of adsorption discs 21 can ensure that the mounting base 11 is stably arranged on the outside of the road foundation pit, and the adsorption specifications of the adsorption discs 21 can be determined according to actual conditions. In the absence of active human interference, the entire protective frame 1 will be in a relatively stable state.

[0032] Furthermore, in order to further protect the bottom of the mounting base 11, in the present embodiment, a buffer pad 22 is provided on the side of the adsorption plate 21 for buffering and protecting the mounting base 11; the buffer pad 22 can be provided to better install the mounting base 11.

[0033] It should also be noted that the specific structure of the above-mentioned adjustment member 3 is as follows: the adjustment member 3 includes a fixed rod 31 arranged on the mounting base 11, and a thread groove 121 is provided in the support frame 12 and is threadedly connected to the rod; by rotating the support frame 12, the support frame 12 can be adjusted to slide vertically up and down on the outer periphery of the fixed rod 31, thereby achieving the purpose of adjusting the height of the plurality of protective rods 13. The purpose of such a setting is also to make the entire protective frame 1 more practical.

[0034] Furthermore, the extension of the horizontal length of the protection rod 13 is arranged by means of an extension lever and a guide slot 131 . When the extension lever slides outward in the guide slot 131 , the extension lever extends outward to further extend the protection rod 13 .

[0035] It should be noted that the sliding of the extension lever in the guide groove 131 has a certain friction coefficient, that is, the extension baffle has a certain resistance when sliding outward, and needs to be pulled manually.

[0036] It is worth mentioning that in order to ensure the stability of the setting of the plurality of protection bars 13, in this embodiment, the plurality of protection bars 13 are sequentially provided with a plurality of connecting rods 14 above and below; the setting of the connecting rods 14 can ensure that the protection bars 13 are set horizontally.

[0037] In addition, in order to provide advance warning for the foundation pit sections of municipal roads, in this embodiment, the outer periphery of several of the protective bars 13 is covered with a warning layer for warning vehicles; the provision of the warning layer can achieve a better warning effect of the protective bars 13 and avoid danger to passing vehicles.

[0038] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
