Construction method for drainage and protection of high cutting slope side ditch
The invention provides a construction method for drainage and protection of a high cutting slope side ditch, a cutting intercepting ditch adopts a V-shaped structure, a slope adopts a trapezoidal structure, and the construction method comprises the following steps: carrying out construction lofting; construction of an intercepting ditch is conducted; excavating the cutting soil layer by layer; the slope in a preset range from the bottom elevation of the drainage ditch to the top is subjected to mortar rubble masonry slope protection; installing a water drain pipe in the mortar rubble; the slope surface, close to the roadbed, of the side ditch is constructed through cast-in-place concrete or a prefabricated panel, and the bottom of the side ditch is made of cast-in-place concrete. The slope form mainly comprises main structures such as the prefabricated concrete panel, the slope protection slurry rubbles, the drainage holes and the geotechnical cloth isolation layer, and the cutting slope protection and water interception and drainage effects can be effectively improved through the side ditch and protection slope combination form; the problem that the scouring phenomenon exists in transition connection of an existing V-shaped side ditch or U-shaped side ditch and side slope protection is solved.
本发明提供了一种用于高路堑边坡边沟排水及防护的施工方法，路堑截水沟采用V字形结构，边坡采用梯形结构，包括：进行施工放样；进行截水沟的施工；进行路堑土质的逐层开挖；自排水沟底标高开始向上预设范围内的边坡处采用浆砌片石砌筑护坡；在浆砌片石内安装泄水管；边沟靠近路基一层坡面采用现浇混凝土或预制面板对边沟靠近路基一层坡面进行施工，且边沟沟底采用现浇混凝土。本发明中边坡形式主要包含预制混凝土面板、边坡护坡浆砌片石、泄水孔、土工布隔离层等主要结构，通过边沟及护坡组合形式可有效提高路堑边坡防护及截排水作用，解决了现有V型边沟或U型边沟与边坡防护的过渡连接都存在冲刷现象的问题。
