Assembly type composite soil nailing wall supporting structure and construction process thereof
The invention discloses an assembly type composite soil nailing wall supporting structure and a construction process thereof, and solves the problems that an existing soil nailing wall supporting structure is poor in shockproof effect on slope protection with high stone content in an earthquake-prone area, and soil nails are likely to loosen and fall off to cause collapse; the assembly type composite soil nailing wall supporting structure comprises a protective surface layer and a composite steel pipe, wherein the composite steel pipe is inserted into a protective slope, the composite steel pipe is detachably connected with the protective surface layer through a connecting piece, the composite steel pipe comprises a hollow core pipe, a pipe sleeve and side pipes, the core pipe comprises acone bottom and a column body, the pipe sleeve is sleeved on the outer layer of the core pipe, a gap is formed between the pipe sleeve and the core pipe to form an interlayer cavity, and the side pipes are arranged in the interlayer cavity and communicate the inner cavity of the core pipe and the outer part of the pipe sleeve, the interlayer cavity is filled with elastic concrete, the inner cavityof the core pipe and the side pipes are filled with concrete, and the composite steel pipe and the surrounding protective slope soil are filled with concrete. The assembly type composite soil nailingwall supporting structure and the construction process thereof have the advantages of stable structure, good anti-vibration effect and the like.
本发明公开了装配式复合型土钉墙支护结构及施工工艺，解决了现有的土钉墙支护结构对地震频发区的含石量高的边坡防护的防震效果欠佳，可能引起土钉松动脱落发生塌方的问题，本发明包括防护面层和复合钢管，复合钢管插入防护边坡中，复合钢管通过连接件与防护面层可拆卸连接，复合钢管包括中空的芯管、管套以及侧管，芯管包括锥底和柱体，管套套装在所述芯管的外层，所述管套与芯管之间具有间隙形成夹层腔体，侧管设置在所述夹层腔体中，并且连通芯管的内腔和套管的外部，夹层腔体中填充有弹性混凝土，芯管的内腔和侧管中填充有混凝土，复合钢管与周围的防护边坡土中填充有混凝土。本发明具有结构稳固、防震效果好等优点。
