The concrete meaning of language in the present invention.
A kind of extension type erosion control limit person's fence, including the first fixed hurdle 1, telescopic column 2, the second fixed hurdle 3 and fence
Door 4, the telescopic column 2 is connected between first fixed hurdle 1 and second fixed hurdle 3, and the lattice door 4 is pacified including door
402 and door leaf 401 are shelved, described 401 one end of door leaf is hinged on a mounting rack 402, and 401 other end of door leaf and second is consolidated
Determine column 3 to be docking together far from one end of telescopic column 2, the left end of the right end and door leaf 401 of second fixed hurdle 3 is respectively welded
It is fixed with lock nose 6, two lock noses 6 are locked together by lockset.The telescopic column 2 includes no less than two and is telescopically plugged on
Plug-in unit together, the plug-in unit include rectangle pipe support, the rectangle pipe support include horizontally disposed upper casing 201,
The vertical tube of setting of casing 202 and the preset quantity being welded between casing 201 and setting of casing 202 vertically, the upper casing 201
It is respectively welded with the right end of setting of casing 202 and is fixed with inserted link 203,2 inserted links 203 of previous plug-in unit are pullably inserted respectively
Enter into the upper casing 201 and setting of casing 202 of latter plug-in unit.The rectangle pipe support of the 2 left end plug-in unit of telescopic column
Left end and the right end of the first fixed hurdle 1 be welded and fixed；Second fixed hurdle 3 include upper crosstalk tube 301, lower crosstalk tube 302 and
It is welded on the vertical tube of the preset quantity between upper crosstalk tube 301 and lower crosstalk tube 302, the 2 right end grafting of telescopic column vertically
2 inserted links 203 of unit are pullably inserted into respectively in the upper crosstalk tube 301 and lower crosstalk tube 302 of the second fixed hurdle 3.The
The bottom end of one fixed hurdle 1, telescopic column 2 and the second fixed hurdle 3 is respectively fixed with the stabilizer blade 5 of preset quantity.Described first is fixed
Column 1 and door leaf 401 are respectively the frame structure being welded by the transverse pipe of preset quantity and the longitudinal pipe of preset quantity.
The upper casing 201 of plug-in unit, the upper crosstalk tube 301 of setting of casing 202 and the second fixed hurdle 3, lower crosstalk tube 302
Six steel splitting pipes are all made of, inserted link 203 uses the reinforcing bar of diameter 12mm.
In use, the left end of the first fixed hurdle 1 is fixed on the lane side of side by anchor pole, the mounting rack 402 of lattice door 4 is logical
Anchor pole is crossed to be fixed on the lane side of the other side.After the installation is completed, when tunnel is squeezed and deformed because of bump, telescopic column 2 by
Power is shunk, i.e., inserted link 203 is inserted more deeply into the upper casing 201 and setting of casing 202 of latter plug-in unit, so that flexible
2 overall width of column becomes smaller, and produces adaptive change, and then avoids this extension type erosion control limit person fence itself and be extruded
Deformation, damage, greatly reduce failure rate.In addition, this retractility is not easy this extension type erosion control limit person's fence
It because lane side extruding is stuck between lane side, and then avoids and is not easy the problem of moving because being stuck between lane side, convenient for recycling.
