Technical Field
The invention relates to the technical field of dangerous rock mass remediation, in particular to a steel wire rope binding structure of a huge dangerous rock mass.
Background
The dangerous rock mass is an unstable rock mass on a high and steep slope or a scarp under the actions of self gravity, earthquake, weathering, structural surface and the like. In mountain railways, particularly in western mountainous railways of China, dangerous rock masses have become one of the main geological disasters threatening railway traffic safety, and huge dangerous rock masses (generally with the volume of more than 10000 m)3Dangerous rock mass) has larger danger to the safety of railway traveling due to high position and huge volume. Once the huge dangerous rock mass collapses, the impact energy of the huge dangerous rock mass is enough to ensure that the original protection measures are invalid, the light people cause the interruption of the railway running, and the heavy people cause the overturn of the train or serious injury to the personnel.
At present, the method and means for remedying dangerous rock masses are limited, and can be divided into two types according to technical measures: active and passive protection systems. The active protection system aims at improving the stability of dangerous rock masses and preventing the dangerous rock masses from collapsing, and the active protection system mainly comprises blasting clearing and in-situ reinforcement, and the in-situ reinforcement comprises anchoring, supporting, grouting, a protective net, a stone guiding net and the like. The passive protection system aims at setting up a protection structure to intercept and prevent falling rocks from damaging a protected object, and the main measures comprise a shed tunnel, a stone blocking wall, a falling rock groove, a flexible passive protective net and the like.
In the prior art, the two measures can be implemented for small dangerous rock masses, and the passive protective net measure is a main method for treating the small dangerous rock masses due to low cost, short construction period and less construction limitation.

After the lap joint section is fixed by the rope clamp, the exposed length of the tail end of the lap joint section is not less than 20 cm. Generally, the length of the lap joint section is not shorter than three meters (when the diameter of the steel wire rope is 60 mm), a plurality of rope clamps can be adopted for clamping and fixing, and the distance between every two adjacent rope clamps is not less than 36 cm.
In this embodiment, the rope clip includes curved arc strip and removal strip 400 of arc, and the arc strip includes crooked section 301 and two straight section 302, and the upper end of two straight section 302 corresponds respectively to connect the tip at crooked section 301, and the lower extreme of straight section 302 extends downwards and arranges, and crooked section 301 encloses with two straight section 302 and forms lower extreme open-ended centre gripping space.
Remove strip 400 and span the lower extreme opening in centre gripping space, the centre gripping space is passed in the lower extreme activity of two straight strip sections 302, be connected with on the linkage segment and adjust head 500, adjust head 500 and straight strip section 302 threaded connection, like this, through rotating adjustment head 500, adjust head 500 then can reciprocate along straight strip section 302, when adjusting head 500 and corresponding upwards, then driving and moving strip 400 and moving towards crooked section 301, reduce the height in centre gripping space, adjust head 500 and support from bottom to top and move strip 400.
The lapping sections of the two steel wire ropes 101 penetrate through the clamping space, the two lapping sections are arranged in an up-down stacking manner, and the two straight sections 302 are respectively clamped at two sides of the two lapping sections; by rotating the adjusting head 500, the moving strip 400 is driven to move towards the bending section 301, and the bending section 301 and the moving strip 400 clamp the two overlapping sections up and down until the clamping force of the bending section 301 and the moving strip 400 on the two overlapping sections is greater than a set value.
Along with rotating the first 500 removal of regulation, adjust first 500 drive and remove strip 400 and move towards crooked section 301, shorten the height in centre gripping space, constantly increase crooked section 301 and remove the dynamics of strip 400 two overlap joint sections of centre gripping in opposite directions, until two overlap joint sections between firmly by the centre gripping.
In this embodiment, the adjusting head 500 is a hexagon nut, the hexagon nut is sleeved with a limiting cylinder 704, a limiting hole with an open upper end and a hexagonal shape is formed in the limiting cylinder 704, a hook strip 700 is connected to the limiting cylinder 704, the hook strip 700 extends upwards, and a hook 701 is arranged on the hook strip 700; a hexagonal limiting plate 702 which moves up and down along a limiting cylinder 704 is arranged in the limiting hole, and a spring 703 is arranged between the limiting plate 702 and the bottom of the limiting hole;
after the adjusting head 500 rotates upwards to the set position, the limiting cylinder 704 is sleeved outside the adjusting head 500 from bottom to top, and the outer side wall of the adjusting head 500 is in butt joint with the inner side wall of the limiting cylinder 704, so that the rotation of the adjusting head 500 is limited. The bottom of the adjusting head 500 is pressed against the limiting plate 702 to drive the limiting plate 702 to move downwards, the spring 703 is compressed, and the hook 701 of the hook strip 700 is clamped on the lap joint section from top to bottom.
After the adjusting head 500 rotates to a set position, in the subsequent use process, when the adjusting head 500 rotates and loosens, the clamping force between the two lap joint sections is reduced, so that the problem that the steel wire rope 101 is not stably bound occurs.
To avoid this phenomenon, by arranging the restricting cylinder 704, first, the adjusting head 500 is inside the restricting cylinder 704, and is engaged with the restricting hole, restricting the rotation of the adjusting head 500; secondly, the spring 703 is compressed and deformed, and drives the limiting plate 702 to press the bottom of the adjusting head 500 upwards, so that the downward movement of the adjusting head 500 is further limited; moreover, the hook 701 on the hook strip 700 is used for fixing and arranging the limiting cylinder 704 and the lap joint section relatively, so that the position stability of the limiting cylinder 704 is ensured.
