[0002] In recent years, green prefabricated slope support systems have been widely used, especially in the fields of highways, railways, urban construction, etc. As a new technology for foundation pit support, its security measures during the construction process are still insufficient and lack a mature security system.
[0003] At present, most of the construction of prefabricated slope support surface layers (systems) do not adopt effective safety measures. When workers lay flexible surface layers, they usually hang safety belts on the guardrails at the top of the slope, or on ladders close to the slope. Generally, when constructing the surface layer below the second row of soil nails, it is extremely inconvenient to hang the safety belts on the guardrails at the top of the slope. Workers cannot easily and quickly take off the safety belts, which greatly increases the safety risk.
[0004] In view of this, there is an urgent need to develop a prefabricated slope support surface construction safety protection device. Utility Model Content

[0029] The utility model provides an assembled slope support surface construction safety protection device.
[0030] Reference Figure 1In one embodiment of the utility model, the prefabricated slope support surface construction safety protection device includes embedded parts 10, mounting parts 20 and protection ropes 30; a plurality of embedded parts 10 are suitable for being embedded in the concrete pressure top layer 100 on the top of the slope support surface layer, and a plurality of the embedded parts 10 are distributed at intervals and have exposed ends exposed to the outside; a plurality of mounting parts 20 are installed one-to-one on the exposed ends of the embedded parts 10; the protection ropes 30 are arranged on a plurality of the mounting parts 20, and the protection ropes 30 are used for workers to take and hang safety belts during construction.
[0031] In this embodiment, the embedded part 10 can be a sleeve or a steel pipe, etc., and an internal thread can be set on the inner wall of the sleeve or the steel pipe. The length of the embedded part 10 can be 50 to 150 mm, preferably 100 mm, which is not limited here.
[0032] In this embodiment, the mounting member 20 may be a bolt with a pull ring, etc., and the bolt is threadedly connected to the embedded member 10. Among them, the pull ring is used for the protection rope 30 to be passed through or bundled, etc., and in order to facilitate the arrangement of the wire rope, the inner diameter of the pull ring should be not less than 20.0mm; in order to ensure the connection strength between the mounting member 20 and the embedded member 10 and avoid the two from being separated and causing safety accidents, the bolt length of the mounting member 20 needs to be set to 150-250mm, preferably 200mm. Of course, in some other application scenarios, the length of the threaded section can be designed by force analysis, and the length of the threaded section can be appropriately increased or decreased while ensuring the safety of the construction personnel.
[0033] It should be noted that in addition to the above-mentioned threaded connection method, the embedded part 10 and the mounting part 20 can also be installed and fixed by welding, clamping or riveting. This article does not limit the structure of the embedded part 10 and the mounting part 20, nor does it limit the connection method between the two.
[0034] In this embodiment, the protective rope 30 can be one or more, and is not limited here. Preferably, the protective rope 30 is a steel wire rope, and the diameter of the steel wire rope can be 7.5-8.5 mm, preferably 8.0 mm. The steel wire rope can be multiple sections, and every 4 steel wire ropes on the mounting parts 20 form a section. The length of each section of the steel wire rope is 3.5-4.5 m. Generally, for a 6 m deep foundation pit, the slack length of the steel wire rope is preferably 4 m. It is more convenient for workers to take and hang the safety belt, and it can be flexibly moved, making the construction more convenient and efficient.
[0035] In this embodiment, in order to further ensure the safety of construction, an anti-fall lock can be provided on the protective rope 30. The anti-fall lock is installed on the loose wire rope, and when the worker slowly pulls the wire rope, the wire rope can be slowly loosened, and when it is pulled quickly, the loosening can be stopped instantly. The principle is similar to that of a car seat belt. When the worker is working, the seat belt is hung on the wire rope, which can be flexibly moved left and right, and the worker can remove the seat belt hook at the bottom of the pit.
[0036] It can be understood that the utility model embeds the embedded parts 10 in the concrete top layer 100 on the top of the slope support surface layer, and several of the embedded parts 10 are distributed at intervals and have exposed ends exposed to the outside, and several mounting parts 20 are installed one-to-one on the exposed ends of the embedded parts 10, and then the protective rope 30 is laid on the several mounting parts 20 for workers to take and hang the safety belt during construction, so that the workers can hang the safety belt on the protective rope 30 during construction, which can be flexibly moved, thereby greatly improving the safety of construction and making on-site construction faster and more efficient.
[0037] To further improve construction safety and convenience, reduce the number of embedded parts 10, and save construction costs, in some embodiments, the distance between two adjacent embedded parts 10 may be 2.5 to 3.5 m, preferably 3.0 m, which is not limited here.
[0038] During construction, the following steps can be followed: excavate the first layer of earth, and lay a number of soil nails on the earth; lay the surface layer and pour concrete to form a concrete pressure top layer 100; before the concrete pressure top layer 100 initially sets, bury a number of embedded parts 10; after the strength of the concrete pressure top layer 100 reaches 75%, install a number of installation parts 20 one by one on the number of embedded parts 10; lay protective ropes 30 on the number of installation parts 20 for workers to hang safety belts during construction.
[0039] Specifically, the first layer of earthwork excavation is completed, and after the soil nailing is completed, the surface layer is laid, and then concrete is poured to form a concrete pressure top layer 100. The thickness of the concrete pressure top layer 100 is generally 80-100 mm. Before the initial setting of the concrete pressure top layer 100, the embedded parts 10 are buried at intervals of 3.0 m along the direction of the foundation pit (located horizontally in the middle of the pressure top). After the concrete strength reaches 75% of the target strength, bolts with pull rings are installed, and after tightening, protective ropes such as steel wire ropes 30 are put on. The steel wire rope can be installed in sections with four bolts as a section, and the slack length of each section can be 4 m (the slack length can be adjusted according to the depth of the foundation pit, and the slack length of a 6m deep foundation pit is generally 4 m). Among them, the purpose of making the concrete strength reach 75% is to save construction time as much as possible and ensure the reliability of the entire protection system.
[0040] It should be noted that the thickness of the concrete top layer 100 can be 80-100 mm, and the excavation depth of the earthwork is 1.0-2.0 m, preferably 1.5 m, which is not limited here.
[0041] In addition, to further improve the safety of construction, an anti-fall lock can be installed on the loose wire rope. When the worker pulls the wire rope slowly, it can slowly relax, and when it is pulled quickly, it can stop relaxing instantly. The principle is similar to that of a car seat belt.
[0042] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
