Flexible branch leads system
Technical Field
The utility model relates to a side slope protection engineering field, particularly, relates to a system is led to flexibility branch.
Background
At present, the field of domestic railway slope flexible protection mainly comprises an active net, a passive net, a curtain type net, shed tunnels and the like. The rock fall protection function can be well played for the respective applicable side slope types according to the respective protection principles. However, the protection mode has certain defects in the protection of slopes above railway tunnel portals: for example, for the protection of side slope rockfall above the tunnel portal of a railway, most of the existing lines and newly-built lines are provided with side slope active and passive protective nets, open cut tunnels, shed tunnels and other structures to prevent rockfall, but the protection has certain limitation due to large engineering quantity, high manufacturing cost and the like.
1. An active network: can effectively stabilize the rockfall in a short period, but along with the continuous weathering of side slope rocks, two drawbacks can appear in the initiative net: the metal net sheet has the phenomenon of bulging, the cleaning workload is large, and the collapse of the protective net can be caused for a long time; the prestress applied to the rock by the longitudinal and transverse supporting ropes 2 of the protective net is lost, so that the active net fails.
2. A passive net: because the net sheet of the passive net can be greatly deformed in the process of intercepting falling rocks, the passive net is too low, and the electrified equipment and the train on the railway are damaged by a larger buffer distance; the passive net is too high, and the falling rocks on the slope surface below the passive net cannot be protected; meanwhile, no matter the active network or the passive network is adopted, the intercepted falling rocks are difficult to clean, and the potential safety hazard can be formed due to excessive accumulation.
3. Curtain type net: the bottom of the curtain wire requires sufficient rockfall collection area, which is often not the case at the top of the tunnel opening.
4. Open cut tunnel, shed tunnel: open cut tunnels have high requirements on foundations, but many projects cannot meet the requirement due to complex terrains, and the impact resistance of open cut tunnels and shed tunnels is limited to a certain extent.

Detailed Description
The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.
Examples
As shown in the figures, the flexible layering system of the present invention includes a flexible longitudinal guide slope and a flexible transverse flow diversion slope. The flexible shunt system comprises: the supporting columns 1 are arranged along the longitudinal slope direction, preferably, the system is arranged in a bilateral symmetry mode, the central axes of the supporting columns 1 are arranged along the longitudinal slope of the mountain land, the supporting columns 1 are arranged on the central axes, in order to better achieve guiding and flow dividing, the lengths of the supporting columns 1 are gradually increased downwards along the slope surface, so that the distance from the top end of the intercepting net 5 to the slope surface is gradually increased along the slope surface, and in order to enable the supporting columns 1 to be more stable, the two sides of each supporting column 1 are provided with anchor pulling ropes 4; the top ends of the three longitudinal supporting ropes 3 are intersected and anchored together, and the longitudinal supporting ropes 3 on the two side edges are inclined outwards; the support structure comprises transverse support ropes 2 arranged on two sides of a support column 1 along the cross slope direction, wherein one ends of the transverse support ropes 2 are connected to the top of the support column 1, the other ends of the transverse support ropes 2 are anchored on a mountain body at the position of a longitudinal support rope 3, and energy dissipaters 6 can be arranged on the transverse support ropes 2 according to needs; the intercepting net 5 is connected to the longitudinal and transverse supporting ropes 2, and the intercepting net 5 is closed in a pasting mode at the starting position of the upper end of the longitudinal slope and the longitudinal side edge to form a flexible longitudinal guiding slope surface and a flexible transverse shunting slope surface.
In order to increase the balance of the system, the anchor position of the pull anchor line 4 connected to the same support column 1 is higher than the anchor position of the transverse support line 2.
The flexible guide system is an auxiliary measure for protecting falling rocks at the tunnel portal, and the falling rocks enter the flexible guide system at a lower speed by arranging the curtain type net in the upper area of the flexible guide system, so that the phenomenon that the falling rocks rebound or puncture the net surface greatly due to overlarge impact speed is prevented.
For better guidance and diversion the height of the supporting column 1 increases gradually down the ramp.
The diversion width B, the guide length L, the tail end intercepting height H and the arrangement span can be considered according to actual conditions such as different gradients, falling rock tracks, protection energy levels and the like, because the initial position and the longitudinal side edges of the intercepting net 5 at the upper end of the longitudinal slope are closed in a pasting mode, falling rocks can only move on the net surface, and because the net surface has enough rigidity and has gradients in the longitudinal direction and the transverse direction, the falling rocks are difficult to stay on the net surface and can only roll down to two sides along the slope surface, and the diversion guide and directional accumulation effects are achieved.
According to the above embodiment, alright realize the utility model discloses well. It should be noted that, on the premise of the above design principle, in order to solve the same technical problem, even if some insubstantial changes or retouching are made on the basis of the disclosure of the present invention, the essence of the adopted technical solution is still the same as the present invention, so it should be within the scope of the present invention.
