Long and short pile combined double-row pile retaining wall structure and construction method thereof
The invention relates to a long and short pile combined double-row pile retaining wall structure and a construction method thereof. The retaining wall structure comprises front-row cast-in-situ bored piles arranged at the bottom of graded sand and gravel below a pavement structure and rear-row cast-in-situ bored piles arranged on the edge of the pavement structure, and the upper ends of the rear-row cast-in-situ bored piles extend out of the surface of the pavement structure. A front-row pile crown beam is arranged at the upper end of the front-row cast-in-situ bored pile and connected with the middle of the rear-row cast-in-situ bored pile through a reinforced concrete plate support, a rear-row pile crown beam is arranged at the upper end of the rear-row cast-in-situ bored pile, and a temporary steel pipe anchor pile is arranged below the pavement structure and located on the front side of the front-row cast-in-situ bored pile. Temporary steel pipe inclined struts are connected between the upper ends of the temporary steel pipe anchor piles and the rear-row pile crown beams, and retaining wall protection faces are arranged on the surfaces of the front sides of the rear-row cast-in-situ bored piles. By adopting the double-row pile retaining wall structure combining the long piles and the short piles, the supporting and retaining advantages of the double-row piles can be brought into full play, the safety of road side slopes and slope top buildings is guaranteed, the occupied area can be reduced, and the use width of a proposed road is guaranteed.
本发明涉及一种长短桩结合的双排桩挡土墙结构及其施工方法，挡土墙结构包括设置在路面结构下方级配砂石料底部的前排钻孔灌注桩和设置在路面结构边沿且上端伸出路面结构表面的后排钻孔灌注桩，前排钻孔灌注桩的上端设置有前排桩冠梁，前排桩冠梁与后排钻孔灌注桩的中部通过钢筋砼板撑相连接，后排钻孔灌注桩的上端设置有后排桩冠梁，路面结构下方位于前排钻孔灌注桩的前侧设有临时钢管锚桩，临时钢管锚桩的上端与后排桩冠梁之间连接有临时钢管斜撑，后排钻孔灌注桩的前侧表面设有挡土墙护面。采用长短桩结合的双排桩挡土墙结构，既能充分发挥双排桩的支挡优势，保证道路边坡及坡顶建构筑物的安全，又能减少占地面积，保证拟建道路的使用宽度。
