Space-limited road side safety protection reinforcing system and construction method
The invention relates to the field of highway roadside safety protection, in particular to a space-limited highway roadside safety protection reinforcing system and a construction method, and solves the problems of low foundation stability and poor protection capability of an existing wave-shaped beam guardrail or a common concrete guardrail. The system is laid on the road side, base steel bars are arranged on a base layer of the road side part of the road, guardrail steel bars fixed to the base steel bars are arranged at the road side end of the road, steel pipes are fixed to the bottoms of the base steel bars, cement concrete is poured into the guardrail steel bars to form a protection wall, and cement concrete is poured into the base steel bars to form a base. Cement concrete is poured into the steel pipe to form a steel pipe pile. According to the system, the protection wall, the base and the steel pipe piles are integrally poured, so that the vehicle collision resistance is enhanced, and more serious secondary accidents caused by the fact that vehicles rush out of a road are prevented.
本发明涉及公路路侧安全防护领域，具体为一种空间受限的公路路侧安全防护加固系统及施工方法，解决了现有波形梁护栏或者普通混凝土护栏基础稳固性低，防护能力差的问题。该系统铺设于公路路侧，所述公路路侧部分的基层设置基座钢筋，在公路路侧端设置与基座钢筋固定的护栏钢筋，在基座钢筋底部固定有钢管，在护栏钢筋内灌注水泥混凝土形成防护墙，在基座钢筋内灌注水泥混凝土形成基座，在钢管内灌注水泥混凝土形成钢管桩。本系统通过浇筑一体化的防护墙、基座和钢管桩，使得抵抗车辆撞击能力加强，防止车辆冲出公路而发生更严重的二次事故。
