Referring to Fig. 4, end construction is made of end column 7, support frame 10, bottom plate 11 and basis 12.End column 7, branch
Support 10 and bottom plate 11 are steel pipe or steel plate, and end column 7, bottom plate 11 and support frame 10 form triangle, specifically: end
Column 7 is vertically arranged, and lower end is welded and fixed with bottom plate 11, and bottom plate 11 is horizontally set in basis 12, and the inclination of support frame 10 is set
It sets, 10 upper end of support frame welds together with end column 7, and lower end and bottom plate 11 weld, to enhance stability.End column 7
It is arranged in basis 12 with the lower part of support frame 10, basis 12 is formed with concreting.
Referring to Fig. 2, non-Newtonian fluid tube 1 is slidably connected on obstruction block 5 by stop collar 13, and both ends are anchored with anchorage 6
On end column 7.Between non-Newtonian fluid tube 1 and obstruction block 5, opposite it can be slided in the extending direction of Newtonian fluid pipe 1, so as to
Non-Newtonian fluid tube 1, which is sufficiently deformed, absorbs the energy that impact generates.
Obstruction block 5 is fixed on middle standing pillar 9 by bolt 8.Several groups are fixed on obstruction block 5 along the vertical direction to be used for
The stop collar 13 of non-Newtonian fluid tube 1 is limited, same group of stop collar is located at the same horizontal position, for across same root non newtonian
Fluid hose 1, the effect of obstruction block 5 is first is that fixed non-Newtonian fluid tube, is handed over greatly, non-Newtonian fluid tube is semi-rigid second is that working as impact force
Property or when rigidity, can be deformed by obstruction block and absorb energy, reduce damage to people's vehicle；Certainly, impact force hour also has one
It is set for using；Several middle standing pillars 9 are provided between two radicle columns 7, the same side on all middle standing pillars 9 passes through bolt
8 are fixed with obstruction block 5, and several vertically disposed non-Newtonian fluid tubes 1 are provided between two radicle columns 7.To prevent large size
Vehicle is got over outside outlet, compact car pierce non-Newtonian fluid tube in the following, non-Newtonian fluid tube since upwardly at 30-50cm set
It sets.
Non-Newtonian fluid tube is generally 4~6；To be uniformly distributed impact force suffered by non-Newtonian fluid tube, its spacing
Take 10-20cm.
Consider construction stretching, note non-newtonian fluid, property easy to maintain etc., non-newtonian fluid length of tube is usually no more than
300m.When the guardrail length of required setting is more than 300m, subsection setup.End construction at adjacent two sections is as shown in figure 5, two
End column spacing 35cm-50cm.
End column and middle standing pillar material are steel pipe, 120~170mm of caliber, 4~6mm of wall thickness.Spacing is straight with column
Diameter, buried depth, non-Newtonian fluid tube radical are related, generally take 4m~6m.
Such as Fig. 3, the non-Newtonian fluid tube 1 of the utility model includes flexible metallic hose 2, is filled inside flexible metallic hose 2 non-
Newtonian fluid 3, outside are protected with protective case 4；Flexible metallic hose outer diameter 24mm, wall thickness 2mm；Protective case 4 selects rubber sleeve
Or skin of paint, the effect of protective case 4 are anti-corrosion.Flexible metallic hose 2 is deformable, when impact force is smaller, non-newtonian fluid deformation compared with
Greatly, non-Newtonian fluid tube is integrally in flexible, can fully absorb energy by deformation.To tense non-Newtonian fluid tube, both ends anchor
Gu on the column of end, it is therefore desirable to bear certain pulling force；When Vehicular impact non-Newtonian fluid tube, compared to rubber, plastics
Pipe etc., metal tube can also provide bigger bearing capacity.Preferably, flexible metallic hose, which is adopted, is made of a steel.
Above-mentioned obstruction block 5 is the cylinder that hollow and upper and lower ends are open, and cross section is generally regular hexagon.The non-newtonian flow
Body anticollision barrier application method is as follows:
Step 1: the demand laid according to guardrail, mounting end structure and middle standing pillar 9 and obstruction block.
Step 2: installation flexible metallic hose 2, and be anchored on end column 7.
Step 3: configuration non-newtonian fluid 3, and non-newtonian fluid 3 is injected in flexible metallic hose 2, seal flexible metallic hose
The port at 2 both ends.
Non-newtonian fluid 3 is high molecular polymer, such as polyethylene, nylon, the concentrated solution of rubber etc.；Or macromolecule chemical combination
Object, such as the concentrated solution of starch, protein can be used as non-newtonian fluid.
Configuration process: high molecular polymer (or high-molecular compound) and water are first weighed in proportion.For example, starch is selected to match
When setting non-newtonian fluid, the ratio of starch and water is (2-2.5): 1, it then stirs to paste or paste.
The working principle of the utility model is as follows:
One of non-newtonian fluid is noteworthy characterized by with stress speed and significant soft or hard variation occurs.The utility model benefit
With this characteristic of non-newtonian fluid.Errant vehicle impinges upon in non-Newtonian fluid tube, internal at this time when impact force is smaller
Non-newtonian fluid stress it is slower, non-Newtonian fluid tube deforms larger in flexibility, mainly by end construction balance-impact power, leads to
It crosses non-Newtonian fluid tube and is deformed and carry out abundant energy dissipating, the damage to people's vehicle can be effectively reduced；It is non-at this time when impact force is larger
Newtonian fluid stress is very fast, non-Newtonian fluid tube in semi-rigid or rigid, deform it is smaller, it is common by middle standing pillar and end construction
On the one hand balance-impact power can effectively prevent vehicle to go out road, avoid second accident, on the other hand can deterring by setting
The deformation of block, column, soil matrix absorbs energy, reduces the damage to people's vehicle.
Errant vehicle is hit in guardrail non-Newtonian fluid tube 1, when impact force is smaller, non-newtonian fluid 3 internal at this time
Stress is slower, and non-Newtonian fluid tube 1 is in flexibility, and deformation is larger, mainly by end construction come balance-impact power, by being deformed
Carry out abundant energy dissipating, the advantages of the damage to people's vehicle can be effectively reduced, given full play to Cable Barrier；When impact force is larger, this
When 3 stress of non-newtonian fluid it is very fast, non-Newtonian fluid tube 1 deforms smaller in semi-rigid or rigid, is tied by middle standing pillar and end
Structure common equilibrium impact force, on the one hand can effectively prevent vehicle to go out road, avoid second accident, on the other hand can pass through setting
The deformation of obstruction block, column, soil matrix absorb energy, reduce the damage to people's vehicle, given full play to the excellent of corrugated beam barrier
Point.
