In construction works in strict accordance with thick embankment fill material 4 layered rollings of every 30cm.In the time that embankment fill material 4 paves, rolls the absolute altitude to this layer of steel bar 6 with ribbing or geotechnical grid 7 positions, lay steel bar 6 with ribbing or geotechnical grid 7, its bottom is closely connected with embankment fill material, and then the embankment fill material 4 and rolling of paving, steel bar 6 with ribbing or geotechnical grid 7 are combined closely with embankment fill material 4.Embankment fill material 4 is rolled repeatedly until meet above-mentioned compacting criteria.
(6) laying of steel bar with ribbing and geotechnical grid and anticorrosion
Because the life-span of steel bar 6 with ribbing directly affects service life of reinforced earth bulkhead, therefore before steel bar 6 with ribbing is laid, should first be coated with red paint in steel bar with ribbing 6 outsides or pitch thin layer (the present embodiment is pitch thin layer) does preservative treatment, to improve the corrosion resistance of steel bar with ribbing, extend the application life of steel bar with ribbing.
Each layer of steel bar 6 with ribbing or geotechnical grid 7 first pave embankment fill material, roll to the absolute altitude of this layer of steel bar 6 with ribbing or geotechnical grid 7 positions before laying.Its bottom is closely connected with embankment fill material, should be flattened, stretches while laying steel bar 6 with ribbing, fills front employing stretcher stretch-draw steel bar 6 with ribbing, then with bolt, it is connected as a whole with the syndeton 5 on regular hexagon baffle plate.
Should be by the stretch-draw of lattice chamber while laying geotechnical grid 7, make geotechnical grid 7 in tension state, do not allow lax sense.Then with bolt, it is connected as a whole with the syndeton 5 on regular hexagon baffle plate.Then laying the top of geotechnical grid 7 with bolt, geotechnical grid 7 is being tangled by lattice with bolt.Bolt exposed portions serve is not higher than geotechnical grid 7 height.Connection between geotechnical grid 7, at geotechnical grid 7 not before stretch-draw, connects lattice chamber 7 with lattice chamber connector.And then do preservative treatment at the bolt outside red paint of painting or pitch thin layer (the present embodiment is pitch thin layer), to improve the corrosion resistance of bolt, extend the application life of bolt.
Geotechnical grid type described in the present embodiment is selected according to designing requirement.It is 200MPa that lattice chamber sheet material stretching yield strength is more than or equal to 200MPa(the present embodiment), it is 150N/cm that form junction intensity is more than or equal to 150N/cm(the present embodiment), it is 15% that lattice chamber sheet material elongation at break is less than or equal to 15%(the present embodiment).Lattice chamber sheet height 50～100mm(the present embodiment is 50mm), welding and assembling height 330～1000mm(the present embodiment is 400mm), development size (horizontal × vertical) (4m～13.2m) × (4.5m～5m) (the present embodiment is 4.4m × 5m).Its length is according to the elongated layout of design embankment width broad ways.
(7) repeat (3)～(6) step, complete the construction of all Study on Reinforced Embankments Using constructional devices on embankment, on supporting and protection structure surface, surface drainage ditch is set subsequently; The integral construction of final complete Study on Reinforced Embankments Using constructional device.
The present invention is alternately connected with steel bar 6 with ribbing and geotechnical grid 7 layerings by the syndeton 5 of embankment both sides regular hexagon baffle plate 3 on sustained height, it is embankment fill material 4 that steel bar 6 with ribbing and geotechnical grid 7 run through between two side shields, make regular hexagon baffle plate 3, steel bar with ribbing 6, geotechnical grid 7 form one with embankment fill material 4 and jointly play a role, steel bar 6 with ribbing and there is very high tensile strength, good cross section frictional force.Geotechnical grid 7 can effectively limit the lateral sliding of packing material, can improve shearing resistance and the frictional force of foundation material, thereby in very large range significantly improve the load-carrying properties of common packing material, the embankment soil body had both been reinforced in the combination of two kinds of forms, increase again integrally-built stability, effectively limit the vertical and lateral displacement of embankment, significantly reduced embankment fill material use amount simultaneously, saved place.
Choose typical cross section in this example section and bury the monitoring instruments such as surface settlement point, skew back pipe, hole pressure meter underground, to having carried out long-term subgrade settlement and lateral displacement observation in this section roadbed filling process and after having constructed.It is 8.5cm that the observation end of term records embankment settlement after construction, and soil body lateral displacement amount is 1.3cm, meets the requirement to Expressway Embankment settlement after construction and soil body lateral displacement in standard.The constructional device of the Study on Reinforced Embankments Using of the present embodiment effectively reduces sedimentation and the lateral displacement of Embankment of Soft Earth Foundation, makes settlement after construction and lateral displacement meet the instructions for use of speedway.
