<p><p>
<span style="font-size:14px;"> 下面给大家讲?a href="http://www.viedecemonde.com/glbxhl/" target="_blank">公路波形护栏</a>安装的技巧：</span>
</p>
<p>
<span style="font-size:14px;"> 采用打入法设置立柱。打入法设置立柱，应严格按照钢钎确定的位置，首先安放自制导向器，再将立柱沿导向孔打入，以确保垂直度。立柱打入土中应至设计深度，当打入过深时，不得将立柱部分拔出加以校正，而须将其全部拔出，等到基础压实后重新打入。立柱安装应与设计图纸相符。并与道路线形相协调，立柱应牢固地埋入土中，达到设计深度，并与路面垂直。如打入困难时，可采用钻孔法或开挖法安装立柱。当采用钻孔法进行立柱安装时，立柱定位后应与路基相同的材料回填，并分层填密实，使其具有不低于相邻原状土的密实度。当采用开挖法施工，埋设立柱时，回填料应采用良好的相同材料，并分层夯实（每层厚不得超过375px），回填土的压实度不应小于相邻原状土。岩石中的柱桩应用粒料回填并夯实?/span>
</p>
<p style="text-align:center;">
<span style="font-size:14px;"><img src="/uploads/image/20180427/20180427163257_0242.jpg" alt="公路波形护栏安装" width="573" height="373" title="公路波形护栏安装" align="" /><br />
</span>
</p>
<p>
<span style="font-size:14px;"> 考虑到护栏结构对景观及驾驶员的视线诱导的影响，立柱安装就位后，应立即进行垂直度位置，标高的检查。垂直度检查采用靠尺量道路中心线与立柱横向间距。标高的检查。垂直度检查采用靠尺逐根，位置检查，间距检查直线采用钢尺检测，曲线段采用偏角法使用经纬仪检测，横向位置检查采用尺量道路中心线与立柱横向间距。标高检查，以路缘石内侧路面为基准，采用自制模或水准仪逐根检查。其水平方向和竖直度方向应形成顺畅的线形。渐变段及端部立柱的安装为施工时需重点注意的部位，施工中应严格控制立柱位置、高度、注意抛物线形。严格按设计文件要求选购材料，所有钢板（管）按设计文件要求必须有材质证明，经验收方可加工?/span>
</p>
<p>
<span style="font-size:14px;"> 支柱须砼基础强度达到设计75%以上时方可安装。支柱通过法兰盘与基础连接。清理完底法兰盘和地脚螺栓后，立直支柱，在拧紧螺栓前应调整好方向和垂直度，后拧紧地脚螺栓。悬臂梁可在安装支柱前与支柱拼装完后一起安装?/span>
</p>
<p>
<span style="font-size:14px;"> 在调整好立柱后，即可安装托架（防阻块）。托架（防阻块）通过连接螺栓固定于波形梁与立柱之间。在拧紧连接螺栓前应调整托架（防阻块）使其准确就位。波形梁通过拼接螺栓相互拼接，并由连接螺栓固定托架（防阻块）上，路基护栏、波形梁的搭接方向是安装的关键，严格按照图纸进行安装。搭接方向应与行车方向一致。波形梁在安装过程中应不断进行调整。因此，不应过早拧紧其连接螺栓和拼接螺栓，以便在安装过程中利用波形梁的长圆孔及时进行调整，使其形成平顺的线形，避免局部凹凸。当护栏的线形认为比较满意时，方可后拧紧螺栓。托架（防阻块）与波形梁之间连接螺栓不宜拧得过紧，以便利用长圆孔调节温度应力。端头梁通过拼接螺栓与标准段护栏相互拼接。端头梁施工方法与波形梁基本相同，分段施工完毕后，自检合格并报请监理工程师验收?/span>
