Inverted U-shaped soil nail supporting structure and construction method thereof
The invention provides an inverted-U-shaped soil nail supporting structure which comprises an after-slope soil body, inverted-U-shaped soil nails, horizontal pressing ribs, slurry and a surface layer, soil nail holes are evenly formed in an excavated slope surface at intervals, the inverted-U-shaped soil nails are inserted into the soil nail holes, the slurry is poured into the soil nail holes to fix the inverted-U-shaped soil nails in the soil nail holes, the ends of the inverted-U-shaped soil nails are exposed out of the soil nail holes, and the surface layer is arranged on the surface layer. The reinforcing mesh of the surface layer covers the excavated slope surface, and the horizontal pressing ribs are parallel to the excavated slope surface, penetrate through the ends of the inverted-U-shaped soil nails exposed out of the soil nail holes and are tightly pressed on the reinforcing mesh. The invention further discloses a construction method of the inverted-U-shaped soil nail supporting structure. A single soil nail rod is replaced with the inverted-U-shaped soil nail in the technical scheme, the steel consumption of the soil nail rod is reduced on the premise that the bond stress is guaranteed, and the production cost is saved. The ends, exposed out of the soil nail holes, of the inverted-U-shaped soil nails are simply and firmly connected with the horizontal pressing ribs, welding is not needed, the construction process is simplified, and production efficiency is improved.
本发明提供一种倒U型土钉支护结构，包括坡后土体、倒U型土钉、水平压筋、浆体和面层，开挖坡面上均匀间隔布设土钉孔，倒U型土钉插入所述土钉孔内，浆体灌注于土钉孔内固定倒U型土钉于土钉孔内，倒U型土钉的端头露出土钉孔，面层的钢筋网覆盖于开挖坡面上，所述水平压筋平行于开挖坡面穿过露出土钉孔的倒U型土钉的端头压紧在钢筋网上。还公开了一种倒U型土钉支护结构施工方法。本发明中将单根土钉杆换成本技术方案中的倒U型土钉，达到同样保证握裹力的前提下，节约土钉杆的用钢量，节约了生产成本。倒U型土钉露出土钉孔的端部与水平压筋连接简单而牢固，无需焊接，简化了施工过程，提高了生产效率。
