To those of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood in combination with the specific situation.
Combine the attached drawing, the utility model discloses a multi-functional counterfort formula barricade in fill district, including setting up outer row of stake 11 and interior row of stake 12 around the side slope, wherein, outer row of stake and interior row of stake constitution double row stake 1, wherein outer row of stake 11 keeps away from the hillside more for interior row of stake 12, and outer row of stake 11 is closer to the toe for interior row of stake 12, links together through tie beam 3 between outer row of stake 11 and the interior row of stake 12, the lower extreme of outer row of stake 11 and interior row of stake 12 is deepened in the side slope soil body, the original facial line 01 of side slope is extended to the upper end of outer row of stake 11 and interior row of stake 12, bottom plate 7 has been pour at the top of outer row of stake 11 and interior row of stake 12, counterfort formula barricade 2 has been pour to the top of bottom plate 7 between bottom plate 7, one side that is close to interior row of buttress formula barricade 12 is connected with a plurality of reinforced concrete counterfort 5, counterfort 2 and bottom plate 7 between outer row of stake 11 form first road 9, interior row of stake 12 and reinforced concrete compaction are carried out the compaction and are carried out the compaction in the region top of compaction and are formed the compaction at second compaction region top 8. Wherein the compaction region 8 refers to: and backfilling and compacting the area above the original slope line 01. When the compaction area 8 is compacted by backfilling soil, the layered compaction thickness and the compaction degree of the backfilled soil meet the requirements of corresponding specifications.
In some embodiments, a retaining plate 6 is disposed between adjacent outer rows of piles 11. In the concrete construction process, firstly, the steel bars are planted on the outer row of piles 11, and then the soil retaining plate 6 and the outer row of piles are connected into a whole through the steel bars.
In some embodiments, the bottom ends of the outer row of piles 11 and the inner row of piles 12 penetrate into the ground below the groundwater level 02.
In some embodiments, the outer row of piles 11 and the inner row of piles 12 are backfilled and compacted. The prior art also has a supporting structure with double rows of piles below and a counterfort retaining wall above, but the distance between the double rows of piles in the prior art is the same as the width of a bottom plate of the counterfort retaining wall, and the structure can cause the distance between the double rows of piles to be smaller, so that the backfill soil between the double rows of piles can not be compacted; on the other hand, the structure is difficult to make the moment balance of the buttress type retaining wall, so that the effect of the presser foot cannot be realized, and the governing effect on the landslide body is limited.
