River road toe protection and slope protection structure and construction method thereof
The invention discloses a road toe protection slope protection structure along a river and a construction method of the road toe protection slope protection structure. Slope toe piles are cement mixing piles and prefabricated square piles which are meshed in a staggered mode, and a horizontal foundation is made of mortar rubbles; geotechnical cloth is laid on the bottom faces of the branch bins, gabion nets are laid on the top faces of the branch bins, gravel-cobbles are filled in the branch bins, the upper edges and the lower edges of the geotechnical cloth are pressed by coping base plates and horizontal foundations respectively, the side edges of the geotechnical cloth extend to block belt foundation grooves, and the lower edges of the gabion nets bypass the lower portions of the horizontal foundations and the side walls of slope toe piles, then enter the top beams and are bound with slope toe pile steel bars and top beam steel bars together. The upper ends of the supporting steel bars penetrate through the coping base plate and then extend into the guardrail foundation, the lower ends of the supporting steel bars are bent at the same slope angle, then extend into the top beam and are welded to the slope toe pile steel bars and the top beam steel bars, and the middle portions of the supporting steel bars are parallel to the slope surface, welded to the anchoring piles on the lower side in a hooked mode and bound to the gabion nets on the two sides. The method is simple in construction, safe and reliable, the original roadbed is stabilized, and the effects of energy dissipation, scour prevention, water and soil loss prevention, silt collection and residue retention of the slope protection and foot protection are enhanced.
本发明公开了一种沿江河道路护脚护坡结构及其施工方法，坡脚桩采用交错咬合的水泥搅拌桩和预制方桩，卧基采用浆砌片石；分仓的底面铺设土工布、顶面铺设石笼网、内部填充卵砾石，土工布的上下边分别由压顶垫板和卧基压住、侧边延伸至格挡带基槽，石笼网下边绕过卧基下部和坡脚桩侧壁后进入冠梁内部并与坡脚桩钢筋和冠梁钢筋共同绑扎，扶位钢筋的上端穿过压顶垫板后伸入护栏基础、下端同坡度角弯折后伸入冠梁并与坡脚桩钢筋和冠梁钢筋焊接，扶位钢筋的中间部分平行于坡面并与下侧的锚定桩钩住焊接、与两侧的石笼网绑扎。本发明施工简单、安全可靠，稳固了原有路基，增强了护坡护脚消能防冲刷、防水土流失、集淤留渣效果。
