Description

Technical Field

[0001] The utility model relates to the field of engineering construction, in particular to a rolling stone blocking device for high and steep slopes. Background Art

[0002] When reinforcing a steep slope, some gravel is likely to slide down the slope and fall onto the road, which can easily cause traffic accidents. The protective structure is a protective measure to prevent gravel on the steep slope from sliding onto the road. It is a device used to avoid road damage and ensure driving safety.

[0003] The Chinese utility model patent (CN214383889U) provides a temporary protection structure for a high and steep slope, which achieves the purpose of blocking the rolling stones of the landslide by providing a plug-in rod, a support column (2) and a protection net, thereby achieving a protective effect. However, it has the following disadvantages in use: 1. It stipulates that the plug-in rod is fixed by workers hammering the plug-in rod. The conditions in the construction area may be different. If the soil in the construction area is loose, it is completely unable to provide support force, and it is completely impossible to block the rolling stones; 2. The protection net is fixed by bolts squeezing to increase the friction force. First, the bolts can be twisted by non-construction personnel, which may easily cause the protection net to fall. Second, the method of increasing the friction force is relatively unreliable, and it is difficult to formulate the installation friction force standard, which is still easy to cause danger.

[0004] Based on the above situation, the utility model proposes a rock rolling barrier device for high and steep slopes to effectively solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] See attached Figure 1-4 A rolling stone blocking device for high and steep slopes, comprising a pile body 1, a plurality of support columns 2 connected to the pile body 1, and a protective plate 5 connected to the support column 2. The side wall of the anti-slope pile is provided with a receiving plate 11. The support column 2 comprises an outer sleeve 21 and an insertion bolt 22. The insertion bolt 22 comprises an insertion rod and a sealing cap 4. The insertion bolt 22 is movably arranged inside the outer sleeve 21. The sealing cap 4 is movably connected to the insertion rod. The outer sleeve 21 and the end of the protective plate 5 are detachably connected to the side wall of the insertion bolt 22. The function of the pile body 1 is to block the landslide sediment. The receiving plate 11 is combined with the support column 2 to ensure that the protective plate 5 has sufficient supporting force to stop the rolling stones and prevent injuries.

[0023] There is a certain damping between the insertion bolt 22 and the outer sleeve 21, and the friction can be increased by conventional means such as adding anti-slip rubber parts. Its function is to prevent people other than construction workers from pulling out the insertion bolt 22. Special tools are required to easily pull out the insertion bolt 22.

[0024] Considering the need to replace the protective plate 5, the insertion plug 22 can be pulled out by unscrewing the sealing cover and lifting the pull ring 41 with a tool such as a crowbar to pull out the insertion plug 22.

[0025] The side wall of the outer sleeve 21 is provided with a plurality of through holes along the height direction, and the side wall of the protective plate 5 is vertically provided with a plurality of fixing plates 51 corresponding to the through holes. The plurality of fixing plates 51 are respectively arranged in the plurality of through holes, and the ends thereof away from the protective plate 5 are detachably connected to the side wall of the insertion bolt 22.

[0026] The receiving plate 11 is provided with a plurality of placement holes 12 penetrating the top and bottom thereof, and the outer sleeve 21 is provided with a clamping module 3 at the bottom thereof, and the clamping module 3 is used to fix the outer sleeve 21 in the placement holes 12 .

[0028] The pile body 1 has a trapezoidal cross section, which has the advantage that its shape can well disperse the force received from the side and convert the force received from the side into downward pressure, thereby increasing friction.

[0029] The clamping module 3 includes two clamping blocks 31 and a spring 32 . A portion of the clamping block 31 extends out of the outer sleeve 21 , and two ends of the spring 32 are fixedly connected to the two clamping blocks 31 .

[0031] The function of the locking module 3 is to fix the support column 2 in the receiving plate 11, and insert the outer sleeve 21 at one end of the slope into the placement hole 12. After insertion, it can be permanently installed to prevent the insertion from being loose, which will cause it to fail to provide the best support when receiving rolling stones.

[0032] A screw rod 42 is disposed at the top of the insertion rod, a pull ring 41 is disposed at the top of the screw rod 42 , and a sealing cap 4 is disposed at the top of the outer sleeve 21 . The sealing cap 4 is inserted into the outer sleeve 21 and sleeved on the screw rod 42 .

[0033] Working principle: first use conventional materials such as reinforced concrete to make the pile body 1, then insert the outer sleeve 21 into the placement hole 12, fix it through the snap-on module 3, and then insert the fixing plate 51 corresponding to the protective plate 5 into the outer sleeve 21 through the through hole 211, and then insert the insertion plug 22 into the outer sleeve 21, and the insertion plug 22 is connected with the fixing hole to complete the installation; if there is a problem with the installation, or when the protective plate 5 needs to be replaced, the sealing cover can be unscrewed, and the pull ring 41 can be pulled out with a tool such as a crowbar for installation.
