防撞墙是桥梁的一种安全防护设施，高速公路防撞墙模具由于防撞墙位于桥面系，处
于桥梁直观的位置，因而对其几何尺寸、表面光洁度、平整度等各项质量指标要求比
较高。但防撞墙下部蹄形部位呈特殊的反弧形，在施工浇筑过程中蹄部前侧面气泡
***难排出，拆模后往往出现较为密集的大小气泡，同时因在安装后的悬空板上现浇
，高速公路防撞墙模具给立模带来很大的难度，模板的接缝部位和底部常常由于漏浆
出现蜂窝麻面等表面缺陷，这些也一直困扰着施工和监理人员。结合工程实际，本文
对防撞墙的质量控制进行浅要分析。
道路防撞墙模具目前广泛应用于住宅小区、校园、体育场、公路道路等不同场所，而
且质量坚固可靠，产品耐用，规格多样，外观精美，优势就是绿色环保。而且在一定
程度上道路防撞墙模具解决了公路安全性的问题，大大减少了交通事故的发生率。由

The anti-collision wall is a kind of safety protection facility of the
bridge. Because the anti-collision wall is located in the bridge deck
system and in the intuitive position of the bridge, the requirements for
its geometric size, surface finish, flatness and other quality indicators
are relatively high. However, the shoe-shaped part at the lower part of
the anti-collision wall presents a special reverse arc. During the
construction and pouring process, it is difficult to discharge the bubbles
* * * on the front side of the shoe, and dense bubbles often appear after
the formwork is removed. At the same time, due to the cast-in-situ on the
installed suspended plate, the formwork of the expressway anti-collision
wall brings great difficulty to the formwork erection, The joint and
bottom of the formwork often have surface defects such as honeycomb and
pitted surface due to slurry leakage, which have also plagued the
construction and supervision personnel. Combined with engineering
practice, this paper analyzes the quality control of anti-collision wall.
At present, the road anti-collision wall mold is widely used in
residential areas, campuses, stadiums, roads and other different places,
with solid and reliable quality, durable products, various specifications
and exquisite appearance. The advantage is green environmental protection.
And to a certain extent, the road anti-collision wall mold solves the
problem of highway safety and greatly reduces the incidence of traffic
accidents. Due to the cost and quality of abrasives involved, the quality
of abrasives can be ensured by using three thick control panels and five
thick rib plates. Therefore, in the case of specific production and
manufacturing of the abrasives, it is not necessary to select thickened
stainless steel thickness. We should pay attention to the control of the
relative density of electric welding and welding and the relative density
of external rib plates, The regulations on the quality of steel abrasives
for anti-collision guardrail shall be completed according to the welding
process. The welding standard is not based on the penetration, but the
relative density must be increased. The interface mode shall be selected
according to the engineering construction regulations. Most of them are
dominated by simple screw connection, which is convenient. In addition, it
is not easy to crack. The key method of applying the abrasive tool is to
brush oil inside the abrasive tool, and there is no need to dismantle the
plate urgently. The longer the drying time is, the better the actual
effect on the coagulation of concrete is, and it is very rapid when the
mold is out, which is beneficial to the maintenance of the abrasive tool.
