Anti anticorrosion wall repair and anticorrosion engineering technology

针对公路两侧桥梁防撞墙及路缘石严重腐蚀破坏等问题，介绍了防撞墙修复防腐试验工程工艺简介，达到防撞墙高效率防锈、防腐、修复的施工目标。

In view of the serious corrosion and damage of the anticollision wall and the road edge stone on both sides of the highway, a brief introduction of the anticorrosion test project of the anticorrosion wall is introduced to achieve the construction target of high efficiency anti rust, anticorrosion and repair of the collision wall.

一、防撞墙病害描述：

First, the wall disease Description:

防撞墙车道内侧钢筋锈胀，钢筋保护层厚度不足。

The inner side of the anti-collision wall is corroded and the thickness of reinforcement cover is insufficient.

二、防撞墙修复方案：

Two. Anticollision wall repair scheme:

主要工序流程：

Main process flow:

①FH-B8002桥隧养护机高压水射流基面清洗

1. Cleaning the base of high pressure water jet for FH-B8002 bridge and tunnel maintenance machine

②外露钢筋涂刷锈转化剂（FH-CX）

(2) exserted steel rebar rusting agent (FH-CX)

③涂刷FH-CTR1防腐材料→

(3) brush FH-CTR1 anticorrosion material.

④涂抹聚合物砂浆（FH-CR/FH-CRⅡ）混凝土修复

(4) application of polymer mortar (FH-CR/FH-CR II) to concrete repair

⑤混凝土表面涂刷FH-JTR1抗渗防腐体系（底涂+面涂）

(5) FH-JTR1 surface impermeable and anticorrosive system on concrete surface (primer + surface coating)
