防撞墙修复防腐工程工艺

Anti anticorrosion wall repair and anticorrosion engineering technology

本文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 this paper, in view of the serious corrosion and damage of the anticollision wall and the road edge stone on both sides of the highway, this paper introduces a brief introduction of the anticorrosion test project of the anticorrosion wall to achieve the construction target of high efficiency antirust, 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) the cleaning of high pressure water jet base surface of FH-B8002 bridge and tunnel maintenance machine.

②外露钢筋涂刷锈转化剂（FH-CX）→

(2) the rust conversion agent (FH-CX) of exserted steel bar

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) apply 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) concrete surface is painted with FH-JTR1 anti-seepage and anticorrosive system (primer + surface coating).
