Abstract
The invention provides a device for protection against rolling stones generated in high slope explosion. The device comprises a stone ridge ditch, a protection steel plate, an obstruction rack and hydraulic elastic support bars, the stone ridge ditch is formed in one side, close to the slope bottom, of an explosion exploitation area, the obstruction rack is arranged at one side of the stone ridge ditch, the protection steel plate is arranged between the stone ridge ditch and the obstruction rack in an inclined mode, the upper end of the protection steel plate is connected with the obstruction rack, the lower end of the protection steel plate is fixed into a rock mass at the slope bottom, protection sandbags are further paved on the surface of the protection steel plate, the multiple hydraulic elastic support bars are arranged at the other side of the obstruction rack in an inclined mode, the upper ends of the hydraulic elastic support bars are connected with the obstruction rack, and the lower ends of the hydraulic elastic support bars are fixed into the rock mass at the slope bottom. The stone ridge ditch serves for the first-stage protection, the protection sandbags, the obstruction rack and the hydraulic elastic support bars serve for the second-stage protection, the steel structure of the obstruction rack has the reinforcement and stabilization effect, double obstruction and interception effect is achieved, the explosion rolling stones can be obstructed in a safe and effective mode, and harm to surrounding residents caused by the explosion rolling stones is avoided.
Description
Technical field
The present invention relates to a kind of high slope explosion Rolling Stone retention device.
Background technology
At present, along with socioeconomic fast development, local infrastructure construction is all being accelerated in various places, as residential architecture, office building, railway and highway etc., part outdoor massif stripping explosion is moved towards resident gradually and is assembled the cities and towns on ground and the edge in village, cause blasting environment to become increasingly complex, explosion harm risk constantly increases.The harm of explosion Rolling Stone is one of its Major risk factors, if explosion Rolling Stone can not be effectively controlled, very easily causes security incident, the safety of life and property of harm surrounding resident.
Summary of the invention
The object of the invention is: for effective controlled blasting Rolling Stone is to the harm of surrounding resident, create good operating environment, the invention provides a kind of high slope blasting protection Rolling Stone device, this device can tackle explosion Rolling Stone safely and effectively, avoids the security incident that explosion Rolling Stone causes.
Technical scheme of the present invention is achieved in that a kind of high slope blasting protection Rolling Stone device, comprise stone dam ditch, shoulder guard, stop bracket, hydraulic elastic support bar, in side at the bottom of slope, blasting excavation district, stone dam ditch is set, in the side of stone dam ditch, stop bracket is set, shoulder guard is obliquely installed between stone dam ditch and stop bracket, the upper end of shoulder guard is connected with stop bracket, the lower end of shoulder guard is fixed in the bed rock body of slope, protection sandbag is also covered with on shoulder guard surface, many hydraulic elastic support bars are obliquely installed at the opposite side of stop bracket, hydraulic elastic support bar upper end is connected with stop bracket, hydraulic elastic support bar lower end is fixed in the bed rock body of slope.
Described stone dam ditch bottom width 1m, top width 2m, high 2m.
The angle of described shoulder guard and horizontal plane is 45 degree.
The angle of described hydraulic elastic support bar and horizontal plane is 60 degree.
Described shoulder guard is overlapped by the plurality of steel plates cell block of size 2m × 3m to form, and the adjacent steel plate lap of splice is 10-20cm.
After a kind of high slope blasting protection of the present invention Rolling Stone device adopts above technical scheme, there is following effect: stone dam ditch is first order protection, protection sandbag and shoulder guard, stop bracket, hydraulic elastic support bar are second level protection, stop bracket steel design has again the effect strengthening steadiness, serve double cutting off inflow interception, explosion Rolling Stone can be stopped safely and effectively, avoid explosion Rolling Stone to work the mischief to surrounding resident, and create good operating environment.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present invention;
Reference numeral: 1-slope bed rock body; 2-hydraulic elastic support bar; 3-stop bracket; 4-sandbag; 5-shoulder guard; 6-stone dam ditch; 7-treats quick-fried massif; 8-blasting excavation region.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, treat that the top of quick-fried massif 7 is blasting excavation regions 8, treat that the bottom of quick-fried massif 7 is slope bed rock bodies 1, owing to treating that quick-fried massif 7 itself has certain altitude, the Rolling Stone in such blasting excavation region 8 will along treating that quick-fried massif 7 rolls down slope bed rock body 1, if slope bed rock body 1 has resident family, the safety of resident family will be injured.
Stone dam ditch 6 is set in side at the bottom of slope, blasting excavation region 8, stone dam ditch 6 bottom width 1m, top width 2m, high 2m; The length of stone dam ditch 6 extends to safety zone along side at the bottom of slope, and stone dam ditch 6 is equivalent to one-level protection.
In the side of stone dam ditch 6, stop bracket 3 is set, shoulder guard 5 is obliquely installed between stone dam ditch 6 and stop bracket 3, shoulder guard 5 and level ground are in angle of 45 degrees and vertical height is 2m, shoulder guard 5 is overlapped by the steel plate block of size 2m × 3m thickness 1cm to form, the adjacent steel plate lap of splice is 10-20cm, the upper end of shoulder guard 5 is connected with stop bracket 3, the lower end of shoulder guard 5 is fixed in slope bed rock body 1, also be covered with protection sandbag 4 on shoulder guard 5 surface, the sandbag 4 on shoulder guard 5 surface is double-deck.
Be obliquely installed many hydraulic elastic support bars 2 at the opposite side of stop bracket 3, hydraulic elastic support bar 2 upper end is connected with stop bracket 3, and hydraulic elastic support bar 2 lower end is fixed in slope bed rock body 1, and hydraulic elastic support bar 2 becomes 60 ° of angles with horizontal plane.
