Abstract
The invention discloses a kind of collapse rock-fall interception structure, including：Rock mass, safeguard structure construction section and working face, the safeguard structure construction section has multistage protection net, every grade of protection network, which is leaned on the safeguard structure construction section of rock mass side, has multistage rock collection structure, and entrapping tank is buffered with breeze way, increase is actively transformed by the passive net of stepped arrangement, multi-buffer, retain step by step, friction subtracts energy, and collapse rock-fall is retained in arc groove, the potential safety hazard that guipure is got in spring is hit so as to solve collapse rock-fall, it is ensured that the safety of working face.
Description
Technical field
The present invention relates to building field, more particularly to a kind of collapse rock-fall interception structure.
Background technology
For rock side slope, when there is collapse rock-fall, the measure of passive net protection can be taken, but when the falling rocks amount of dropping is big
And when buffer distance is limited between passive net, the prophylactico-therapeutic measures that exclusive use is passively netted can not be fully solved collapse rock-fall and hit
Hit the potential safety hazard that guipure is got in spring.
The content of the invention
It is an object of the invention to：Overcome the above-mentioned problems in the prior art, propose that a kind of collapse rock-fall intercepts knot
Structure, is retained, rubbed with breeze way, increase buffering entrapping tank, multi-buffer is actively transformed by the passive net of stepped arrangement step by step
Subtract energy, collapse rock-fall is retained in arc groove, so that solving collapse rock-fall hits the potential safety hazard that guipure is got in spring, protect
Demonstrate,prove the safety of working face.
The purpose of the present invention is realized by following technical proposals：
A kind of collapse rock-fall interception structure, including：Rock mass, safeguard structure construction section and working face, the safeguard structure construction section
With multistage protection net, every grade of protection network is by having multistage rock to collect knot on the safeguard structure construction section of rock mass side
Structure.
A kind of collapse rock-fall interception structure of the present invention, the safeguard structure construction section ramp structure, close to rock mass
Side height is higher.
A kind of collapse rock-fall interception structure of the present invention, the rock collection structure is to safeguard structure construction section
Face collection groove arranged below.
A kind of collapse rock-fall interception structure of the present invention, the collection groove has lead-in chamfered by rock mass side.
A kind of collapse rock-fall interception structure of the present invention, lead-in chamfered described in next stage extends to upper level and collects recessed
Slot space top, so as to form anti-skidding to the rock for falling into collection groove.
A kind of collapse rock-fall interception structure of the present invention, the protection network includes first order protection network and the second level is anti-
Protecting wire net, the height of the first order protection network is less than second level protection network.
A kind of collapse rock-fall interception structure of the present invention, the first order protection network and second level protection network and protection
The angle that structure installs section surface is more than 90 degree.
A kind of collapse rock-fall interception structure of the present invention, has protection diagonal brace on the outside of protection network described in per one-level.
A kind of collapse rock-fall interception structure of the present invention, the collection groove is to be obliquely installed in length direction.
According to above-mentioned technical proposal, the beneficial effects of the invention are as follows：A kind of collapse rock-fall interception structure is proposed, passes through ladder
The passive net of shape arrangement is retained step by step with breeze way, increase buffering entrapping tank, multi-buffer is actively transformed, and friction subtracts energy, by avalanche
Falling rocks is retained in arc groove, so that solving collapse rock-fall hits the potential safety hazard that guipure is got in spring, it is ensured that working face
Safety.
Brief description of the drawings
Fig. 1 is a kind of collapse rock-fall interception structure schematic diagram of the invention.
Embodiment
With reference to specific embodiments and the drawings, the present invention is further illustrated.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As Fig. 1 be a kind of embodiment of collapse rock-fall interception structure of the invention, a kind of collapse rock-fall interception structure, including：
Rock mass 1, safeguard structure construction section 2 and working face 3, the safeguard structure construction section have multistage protection net, every grade of protection
Net, so as to form multistage protection, disappears step by step by having multistage rock collection structure 6 on the safeguard structure construction section 2 of rock mass side
Can, the raising protection reliability that maximum is limited.
The ramp structure of safeguard structure construction section 2, close to the side of rock mass 1, height is higher, and so the rock dropped is entered
Row water conservancy diversion.
The rock collection structure 6 is the collection groove 62 set to the below ground of safeguard structure construction section 2, so step by step
Falling rocks is collected, upper rock-drop accumulations are prevented.
The collection groove 62 has lead-in chamfered 61 by the side of rock mass 1, is so easy to falling rocks to enter collection groove.
Lead-in chamfered 61 described in next stage extends to the space top of upper level collection groove 62, so as to falling into collection groove
62 rock forms anti-skidding, and general development length is 1/6th of collection groove opening size.
The protection network includes first order protection network 7 and second level protection network 4, and the height of the first order protection network 7 is low
In second level protection network 4, because ground is put preferably, or three-level level Four and more stages.
The first order protection network 7 and second level protection network 4 and the angle on the surface of safeguard structure construction section 2 are more than 90 degree,
The falling rocks head that can so make previous stage fail to block enters next stage, prevents the damage of protector.
There is the first order to protect diagonal brace 8 in the outside of first order protection network 7, and the outside of second level protection network 4 has the second level
Diagonal brace 5 is protected, so makes protection network intensity more preferably, the ability for resisting falling rocks is stronger.
The collection groove 62, to be obliquely installed, so can be laterally enriched with, after also allowing in length direction in order to falling rocks
Phase, which is understood forward to one, concentrates accumulation processing.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
