The flexible board 4 stated is then particularly suitable for the centre (i.e. intermediate isolating protective fence) of twocouese expressway, to prevent side vehicle from wearing
More enter the expressway surface of other direction.
For the cushioning effect for further understanding above-mentioned, more specific description is provided in conjunction with attached drawing, the buffer unit is
The clamping piece 9 of one wirerope 3, the clamping piece 9 are fastening wirerope 3 first, and it is the prior art that clamping piece 9, which clamps wirerope 3, therefore not in detail
Diagram and explanatory note, 9 surface of clamping piece have front position shearing folder portion 10 and tail portion to have blocking portion 11, and front herein refers to
The part close to front support arm 7 of clamping piece 9, tail portion refer to part of the clamping piece 9 far from front support arm 7, one end of clamping piece 9
It is placed in the notch 12 of 7 end of front support arm, there is a spacing between blocking portion 11 and position shearing folder portion 10；With wirerope 3
The increase of pulling force, above-mentioned position shearing folder portion 10 are cut off by the notch 12 of 7 end of front support arm, then lose the clamping of blocking
After 9 fast offset of part, one spacing, the blocking portion 11 of clamping piece 9 is contacted with notch 12 makes the fast offset of clamping piece 9 stop, on
The fast offset process stated makes the active force pop-off of entire protective fence, when fast offset stops, entire protective fence it is interior
Portion's stress re-establishes under moving vehicle effect of inertia, i.e. the Vehicular impact phenomenon of duration is separated from the point of view of mechanics
For secondary impact, this makes the time of entire knockout process greatly increase, and Impact energy has more times to be dispersed to far
Side and soil matrix, make the effect of blocking of protective fence greatly improve, require here be first position shearing folder portion 10 shear strength
Be less than the bending strength of the tensile strength and front support arm 7 of wirerope 3, followed by buffer unit to have a non-resistance displacement away from

The inner surface of the closed-loop 6 of attachment device 2 has an adaptable strip groove 14；It is above-mentioned when closed-loop 6 is set with pile 1
Strip projected parts 13 are mutually chimeric with strip groove 14, and when 7 stress of front support arm above-mentioned, closed-loop 6 has the tendency that rotation, but
Strip projected parts 13 prevent the rotation of closed-loop 6, while Impact energy is passed to pile 1 and is transferred to soil matrix, only work as closing
The strength that ring 6 applies strip projected parts 13 is sufficiently large and cuts off strip projected parts 13, and closed-loop 6 has one to lose turning for resistance
Dynamic process, the rotation process for losing resistance can equally make the stress of each component for the protective fence being impacted become no stress
State, only when closed-loop 6 rotates an angle, and front support arm 7 is made to become one by state of tension, the stress of entire protective fence
State re-establishes.Therefore, the non-resistance rotation process of the closed-loop 6 after being sheared of strip projected parts 13 makes again protective fence
Interrupted by knockout process, i.e., shock be divided into secondary segmenting knockout process, further extend knockout process time and
The distribution and absorption for expanding energy, improve and block effect.Whether above-mentioned strip projected parts 13 are sheared, and additionally depend on envelope
The section configuration of the deflection and strip projected parts 13 of closed loop 6, the deflection such as closed-loop 6 is big, then the inner surface of closed-loop 6 may
Strip projected parts 13 can be crossed；If the deflection of closed-loop 6 is little and the section configuration of strip projected parts 13 is rectangle, then to be cut into
It is main；If the section configuration of strip projected parts 13 is curved surface, then the possibility bigger crossed；If the section configuration of strip projected parts 13 is three
Angular, then the tip portion of possible strip projected parts 13 is sheared the remainder that then closed-loop 6 crosses strip projected parts 13；Therefore item
The selection of the section configuration of shape protrusion 13 is depending on the requirement of specific technology.
Attachment device 2 above-mentioned is socketed with pile 1, and after socket, attachment device 2 is with pile 1 by through above-mentioned envelope
The bolt 15 of closed loop 6 and pile 1 is fastenedly connected again, and the length direction of bolt 15 and highway is in 30 ° of -60 ° of angles, and
On pile 1 make bolt 15 by mounting hole be strip-shaped hole, it is in 90 ° that the length direction of strip-shaped hole is axial with pile 1；Bolt
When 15 penetrating mounting holes, a distance is arranged at bolt 15 and the both ends bottom of strip-shaped hole, when strip projected parts 13 above-mentioned are sheared
Fall or more out-of-date, the rotation of closed-loop 6 could drive bolt 15 while rotate, and at this moment second of non-resistance as above-mentioned turns
It is dynamic；But after the bottom of bolt 15 and strip-shaped hole contacts, bolt 15 prevents the rotation of closed-loop 6, only strong sufficiently large, bolt
15 when being cut, and closed-loop 6 is likely to be rotated further；Resistanceless motion process after above-mentioned bolt 15 is cut is knockout process
In third time there is resistanceless motion process, then so that the stress of each component of protective fence is disappeared again, entire knockout process
Four sections of knockout process are divided into, increase time, consumption and the transmission more energy of entire knockout process to the maximum extent.
