Description
Technical field
The present invention relates to civil engineering, in particular to a kind of safeguard structure of small-sized rockfall.
Background technique
Mountain railway topographic and geologic is complicated, and route is often walked in high and steep mountains, and especially high-speed railway is by line alignment
And place limitation, bridge tunnel is than high, and hill side road base, tunnel disengaging entrance etc. side slope distribution are wide, in natural calamity and engineering activity
Under joint effect, the easily geological disasters such as formation crag, falling rocks, avalanche.The place that Falling Rocks occur is more, frequency is high, random
Property it is strong, it is impossible to guard against, seriously threaten mountain railway construction and operation security.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of safeguard structures of small-sized rockfall, can effectively prevent side
Harm of the slope rockfall to buildings such as roadbed, bridge, tunnels, and structure is simple, easy for construction, and advantageously reduces anti-nurse
The cost of journey.
The technical solution adopted by the present invention to solve the technical problems is as follows:
The safeguard structure of a kind of small-sized rockfall of the invention, it is characterized in that: including armored concrete stone cut off wall, miniature
Stake and elastic cord breaker, armored concrete stone cut off wall are located on the bottom surface of barricade foundation pit, and mini pile is indulged on barricade foundation pit bottom surface
It lays to, lateral separation and to form miniature pile group, in stability of slope rock-soil layer, top extends upwardly into each mini pile lower anchor
In armored concrete stone cut off wall, elastic cord breaker be fixed at armored concrete stone cut off wall on the versant side wall.
The invention has the advantages that in rockfall area in armored concrete stone cut off wall is arranged in side slope, for hindering
Rockfall is blocked, harm of the side slope rockfall to buildings such as roadbed, bridge, tunnels is effectively prevent；Stone is blocked by armored concrete
Elastic cord breaker after wall wall directly bears rock-fall impact effect, is significantly reduced falling rocks to the impact force of wall, and to reinforcing bar
The transmitting of concrete stone cut off wall wall and diffusion impact energy, so that armored concrete stone cut off wall wall be avoided directly to be rushed by falling rocks
It hits, greatly strengthens the impact resistance of structural system；Added by basis of the miniature pile group to armored concrete stone cut off wall
Gu upper part is fixedly connected with armored concrete stone cut off wall, is greatly enhanced in addition to increasing bearing capacity, reducing settlement of foundation
The anti-rock-fall impact ability of the stability of armored concrete stone cut off wall；Structure is simple, easy for construction, and advantageously reduces protection works
Cost.
Detailed description of the invention
This specification includes following two width attached drawing.
Fig. 1 is a kind of elevation of the safeguard structure of small-sized rockfall of the present invention；
Fig. 2 is a kind of plan view of the safeguard structure of small-sized rockfall of the present invention；.
Component, toponym and corresponding label: armored concrete stone cut off wall 10, mini pile 11, horizontal steel are shown in figure
Muscle 12, drain hole 13, elastic cord breaker 20 backfill body 21, barricade foundation pit J.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and embodiments.
Referring to Figures 1 and 2, a kind of safeguard structure of small-sized rockfall of the invention includes armored concrete stone cut off wall
10, mini pile 11 and elastic cord breaker 20.Armored concrete stone cut off wall 10 is located on the bottom surface of barricade foundation pit J, for stopping danger
Rock falling rocks effectively prevent harm of the side slope rockfall to buildings such as roadbed, bridge, tunnels.Mini pile 11 is at the bottom barricade foundation pit J
Longitudinally, laterally interval lays and forms miniature pile group on face, each 11 lower anchor of mini pile in stability of slope rock-soil layer, top to
On extend into armored concrete stone cut off wall 10, reinforced by basis of the miniature pile group to armored concrete stone cut off wall 10,
In addition to increasing bearing capacity, reducing settlement of foundation, upper part is fixedly connected with armored concrete stone cut off wall 10, and steel is greatly enhanced
The anti-rock-fall impact ability of the stability of reinforced concrete stone cut off wall.Elastic cord breaker 20 is fixed at armored concrete stone cut off wall 10
On the versant side wall, rock-fall impact is directly born by elastic cord breaker 20 and is acted on, impact of the falling rocks to wall is significantly reduced
Power, and transmit to 10 wall of armored concrete stone cut off wall and spread impact energy, to avoid 10 wall of armored concrete stone cut off wall
Body directly by rock-fall impact, greatly strengthens the impact resistance of structural system.
Referring to Fig.1, the lateral wall of the armored concrete stone cut off wall 10, vertically interval setting is horizontal within the versant side wall
The top binding of reinforcing bar 12, each horizontal reinforcement 12 and ipsilateral mini pile 11 connects the armored concrete stone cut off wall 10 and leans on versant side
Common native formed is filled between wall and barricade foundation pit J side wall and backfills body 21, blocks stone in armored concrete on 21 top surface of backfill body
Longitudinally spaced setting drain hole 13 in wall 10, the lateral wall of each 13 perforated rebar concrete stone cut off wall 10 of drain hole lean on versant
Side wall.It by soil body moisture after 13 drainage wall of drain hole, prevents from seeping under the surface water, prevents ponding after wall from forming hydrostatic pressure, disappear
Except the bulbs of pressure after cohesive soil filler inundation.
Referring to Fig.1, the elastic cord breaker 20 uses flexible rubber material manufactured goods, to reduce engineering cost,
Generally use waste tire, hold set be fixed on armored concrete stone cut off wall 10 on the versant side wall.
Referring to Fig.1, first segmentation carries out barricade foundation pit J excavation, excavates the drilling of construction mini pile 11 after barricade foundation pit J, clearly
Mini pile reinforcing bar is transferred after sky, binding horizontal reinforcement 12, the pvc pipe of Preembedded drain hole 13, formwork erection are disposable after grouting
Pouring reinforcement concrete stone cut off wall 10.After wall intensity up to form removal after 70%, common soil is backfilled in barricade foundation pit J and is formed
Body 21 is backfilled, and wall back hangs waste tire and forms elastic cord breaker 20.
The above only illustrates general construction of the invention.It is done within the spirit and principles of the present invention
Modifications, equivalent substitutions and improvements etc., should all be included in the protection scope of the present invention.
