Specific embodiment
As shown in Figure 1 and Figure 2, a kind of high gradient crushed stone aggregate transportation system, including feeding platform 1, chute 6, discharge nozzle
10th, outfeed platforms 11, the top of chute 6 connects the outlet of feed hopper 2, and the charging aperture of feed hopper 2 is placed on feeding platform 1；Chute 6
Bottom connects discharge nozzle 10, and the lower section of discharge nozzle 10 arranges outfeed platforms 11.Chute 6 is laid along hillside 7, at interval of a segment distance
One descending lifeline 8 is installed, the control crushed stone aggregate entrance point speed of descending lifeline 8 from top to bottom will be broken by the gravity of crushed stone aggregate
Stone aggregate is transported to destination.
Chute 6 includes multistage chute unit, is connected by first flange 5 between multistage chute unit.Using flange bolt
Connection, not only easy to assembly, and safeguard and be also convenient for, once wherein one section goes wrong, or plugging occur, directly dismounting is wherein
One section is changed and dredged.
Connected by second flange 5 ' between each descending lifeline 8 and chute unit, the junction is provided with concrete buttress
9.Concrete buttress 9 can ensure that stablizing for descending lifeline 8.
It is 8mm steel pipes that the chute 6 is a diameter of 400mm, thickness, by the between the chute unit that multistage steel pipe is constituted
The bolt connection of one flange 5.Using flange bolt connect, it is not only easy to assembly, and safeguard be also convenient for, once wherein one section occur
Problem, or there is plugging, directly remove wherein one section and changed and dredged.
The top of the chute 6 is welded to connect with the outlet of feed hopper 2, and the bottom of chute 6 is welded to connect with discharge nozzle 10.
The feed hopper 2 is welded for steel plate, big upper and lower small mouth, in eight word infundibulate.Width suitable for reading, can be conveniently
Many people simultaneously feeding, lower mouth is little, just slides into chute with crushed stone aggregate.
The feeding platform 1 is builder's road, directly facilitates crushed stone aggregate load wagon discharging using builder's road.
The outfeed platforms 11 are sidewalk and the steel structure platform composition built by the mountain.Outfeed platforms outfeed platforms 11 need
Sand, rubble are stacked, sidewalk usable floor area is limited, it is necessary to build steel structure platform near the mountain.
The concrete buttress 9 is formed by dowel 3 or angle steel 4 by concreting.Dowel or angle steel must enter rock 4.0m,
0.5m is exposed, dowel 3 or angle steel 4 are needed and steel-pipe welding, and then casting concrete, can increase the impact resistance of chute, protect
The firm of chute 6 is demonstrate,proved.
Specific implementation method is as follows：
1st, using Φ 400mm, the steel pipe manufacturing chute 6 of thickness 8mm, connected using flange between steel pipe.
The 2nd, the feed hopper 2 of 1000mm × 600mm is installed, is processed using 3mm steel plates, with L50*50*3 angle steel or the anchors of Φ 28
Muscle welding is supported and pours C25 concrete fixes steel pipe and feed hopper 2,4.5 meters of 28 dowel length of Φ, and grouting rock bolt enters rock 4.0m,
Expose 0.5m.
3rd, 4 ~ 6m is spaced along pipeline direction, is supported and poured C25 concrete with L50*50*3 angle steel, the welding of the dowels of Φ 28 and consolidated
Determine hopper and chute 6.
4th, along pipeline direction interval, 50m installs one " My-Box type descending lifelines ", totally 7, customized in producer, last
Descending lifeline is arranged at the 2m of discharging opening top, for reducing aggregate gliding speed.Descending lifeline is made using 10mm steel plates, length
1.7m。
5th, steel structure platform is set up：
1. using steel I-column basis, array pitch 5.3m × 5.5m between base for post, local pitch reduces, and 14 base for posts are set altogether, and
Sidewalk roadside junction sets 10 concrete bases.First basis dug to basement rock during construction, then by scar bore it is quick-fried dig flat, pour bed course
Concrete.Then assembling reinforcement, cast-in fixing bolt pour foundation concrete, then joist steel upright and anchor bolts are firmly poured into concrete parcel post
Pin.
2. connection beam in length and breadth is arranged in the middle part of pilum using the pipes of Φ 89 × 3, is arranged in intercolumniation using the plain bars of Φ 20
Bridging.
3. 1.0 ~ 1.5m of case bay is longitudinally linked in pilum welded top connection beam in length and breadth using I-steel, is laterally linked
Case bay 5.3m, and L50*50*3 angle steel is welded between horizontal linking beam, top completely spreads 6mm thickness checkered steel plates and firm welding
Form platform.
4. in platform peripheral solder steel tube guardrail, and 3mm steel plate enclosings are completely spread on guardrail.
5. stone masonry dividing wall is built by laying bricks or stones on platform, for stacking sand, rubble；Set up with steel pipe, asbestos shingle on platform
Warehouse, for stacking cement.Platform can store the m of sand 703, the m of rubble 903, cement 30t, 100 m can be poured3Concrete.Storage
Material gross weight about 270t.
6th, port of export metaling speed is controlled within 5m/s, rubble gliding speed is calculated as follows：
Jing consults reference materials, the coefficient of friction u=0.11 between rubble and steel pipe, according to force analysis, mgsin45 °-
Mgucos45 °=ma, calculate slope acceleration a=6.167.
According to formula V2-V0 2=2as can just calculate the speed of rubble any point on the slope.
If not installing descending lifeline, it is 67m/s to be computed rubble in port of export speed, it is clear that do not meet safety requirements.Peace
After dress descending lifeline, each descending lifeline can be by rubble gliding speed（Within 30m/s）Reduce to close to zero, it is negligible.So
Just can be feasible in safety by port of export speeds control within 5m/s.Result of calculation is as follows：
a ：At chute 50m：Descending lifeline upper end speed 24.83m/s, descending lifeline lower end speed 0m/s；
b ：At chute 100m：Descending lifeline upper end speed 24.83m/s, descending lifeline lower end speed 0m/s；
c ：At chute 150m：Descending lifeline upper end speed 24.83m/s, descending lifeline lower end speed 0m/s；
d ：At chute 200m：Descending lifeline upper end speed 24.83m/s, descending lifeline lower end speed 0m/s；
e ：At chute 250m：Descending lifeline upper end speed 24.83m/s, descending lifeline lower end speed 0m/s；
f ：At chute 300m：Descending lifeline upper end speed 24.83m/s, descending lifeline lower end speed 0m/s；
g ：At chute 358m：Descending lifeline upper end speed 26.75m/s, descending lifeline lower end speed 0m/s；
h ：At chute 360m（The port of export）：Speed 4.97m/s.
