波形梁护栏施工过程中应该注意些什么？

Waveform fence construction process should pay attention to what?

一 、立柱放样

A column layout

①、立柱应根据设计图纸进行放样，并以桥梁、通道、涵洞、立交、平交等为控制点，进行测距定位，可利用调整段调节间距，并利用分配方法处理间距零头数。

According to the design drawings of lofting, and bridge, tunnel and culvert, interchange, crossing and as a control point, location, by adjusting the period of adjusting the spacing, and the allocation method to deal with a number of odd spacing, column.

②、为准确放样和保证护栏的线形，隔段进行桩号复核和闭合。

The accurate assurance, lofting and rail alignment, segment pile, review and closure.

③、立柱放样后，应调查每根立柱位置的地表状态，如遇地下通讯管线、泄水等，或涵洞顶部埋置深度不足时，应调整某些立柱的位置，改变立柱固定方式。

(3), a column layout, should be investigated every pillar position of the surface state, in case of underground communication pipeline and water discharge, or the top of the culvert buried depth is insufficient should be adjust some column position to change column fixation.

二、立柱安装

Two, column installation

①、根据设计图纸进行立柱钻孔，并检查使之与道路线形相协调。

According to the design drawings for the drill, and check to make it with the road alignment.

②、如路肩基本情况允许，采用打入法设置立桩，施工时应精确定位，立柱打入土中应至设计深度，当打入过深时，不得只将立柱部拔出加以矫正，而须将其全部拔出，待基础压实后重新打入。

II, if permitted by the basic situation of the shoulder, the use of scoring method is used to set the stake, construction should accurate positioning, column play buried in should to the design depth, when into too deep, not only the column, pull out the corrected, and must be the pull out all, compaction Foundation to be re entered.

③、立柱打入困难时，可采用钻孔法或开挖法安装立柱。采用钻孔法安装，立柱定位后应与路基相同的材料回填，并分层夯填密实；采用开挖法埋设立柱，回填土应采用良好的材料并分层夯实（每层厚不超过15cm），回填土的压实度不应小于相邻原状土。山东君安公路波形梁护栏板厂

When the column is in difficulty, the drilling method or the excavation method can be used to install the column. Installed in the hole drilling method, the orientation of the column should be with the same roadbed backfill material and layered tamping filled and compacted; the excavation method embedded column, backfill should be with good material and compaction in layers, each layer thickness of not more than 15 cm), backfill compaction degree should not be less than the adjacent undisturbed soil.

④、设置于构造物中的护栏立柱，施工一般在结构物施工时已做好砼基础。采用预留孔基础时，应先清除孔内杂物，吸干孔内积水，将化好的沥青在孔底涂一遍，然后放入立柱，控制好标高。即可在立柱周围注砂。在灌砂时一定要保持立柱的正确位置和垂直度。把砂振实后，即可用沥青封口，防止雨水漏入孔内。

Fourth, set in the column in creation, construction in general structure construction has made the concrete foundation. The reserved hole foundation, should first remove the debris inside the hole, water drain hole, the asphalt in the hole bottom painted again, and then into the column, controlling the elevation. Sand around the column. The correct position and verticality in the sand must remain upright. When the sand is compacted, it can be sealed by asphalt, which can prevent the rain from leaking into the hole.

⑤、沥青路面段的立柱施工时，柱坑从路基到面层下5cm采用与路基相同的材料回填并分层夯实，余下部分采用与路面相同材料回填并夯实。

Gymnasium, the asphalt pavement section of column construction and pit prop from the roadbed to 5cm surface layer under the roadbed and the same material backfilling and compaction in layers, and the remaining part of the use and the same road backfill material and lay a solid foundation.

⑥、立柱安装就位后，其水平方向和竖直方向形成平顺的线形。

The post, after installation, the formation of a smooth line of the horizontal direction and the vertical direction.

⑦、渐变段的端部护栏施工时，应按设计规定的坐标严格控制其立柱位置，注意抛物线形。

Seventhly, transition section at the end of the fence construction should be according to the coordinates of the provisions of the design and strict control of the column position, pay attention to the parabolic.

三、防阻块/托架安装：防阻块/托架通过连接螺栓固定到立柱上，在波形梁安装前防阻块/托架与立柱间的螺栓（（M16×170/150）不应过早拧紧，应在护栏板安装到位后再拧紧。

Third, to prevent block / bracket installation: to prevent block / bracket by a bolt connecting to the column, in wave beam before installation to prevent block / between the bracket and the column bolt (M16 x 170/150) in should premature tightening should be in the guardrail plate installed in place to screw up.

四、波形梁护栏板安装

Four, wave beam plate installation

①、波形梁安装时，通过拼接螺栓（M16×35）相互拼接，并由连接螺栓（M16×42）固定于立柱或横梁上。波形梁拼接方向是安装的关键，施工时保证搭接方向应与行车方向一致。

When the wave beam is installed, the connecting bolts (M16 * 35) are connected with each other, and are fixed on the upright post or the beam by the connecting bolt (M16 * 42). The direction of wave beam splicing is the key of the installation, and the overlapping direction should be consistent with the direction of the road during construction.

②、波形梁护栏在安装过程中应不断进行调整，因此连接螺栓及拼接螺栓不宜过早拧紧，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。

II, corrugated beam during the installation process should be adjusted continuously and therefore the connection bolt and bolt joint should not be premature tightening, so that in the installation process in the wave beam hole adjusted in a timely manner, to form a smooth linear and avoid local bump.

③、安装时波形梁顶面应与道路竖曲线相协调。并检查护栏的线形，当确定线形比较直顺和流畅时，方最后拧紧螺栓。www.sdboxinghulan.com

In the installation, the top surface of the wave beam should be coordinated with the vertical curve of the road. And check the fence line, when determining the linear and smooth straight, and tighten the bolts. Www.sdboxinghulan.com

五、端头安装：端头安装应根据设计图设计的地锚端头及圆端头、中央开口端头等不同结构分别安装在不同的位置，凡需混凝土浇筑基础的地方，必须等到混凝土强度达到设计强度的70%以上拧紧连接螺栓。

Fifth, the head end installation: installation end should according to the design of the anchor head and round head end, the central opening side of the top of different structures were installed in different locations, where the required foundation concrete pouring must wait until the concrete strength reaches 70% of design strength of connecting bolt is tightened.

六、注意事项：护栏在吊装、运输、堆放过程中应固定可靠，防止因颠簸碰撞损坏涂层或使构件变形。护栏施工时不得破坏路面下埋设的电缆、管道等设施。

Six, matters needing attention: in the process of hoisting, transportation and stacking, the guard rails should be fixed and reliable, prevent the coating or the deformation of the component due to bump collision. Guardrail construction shall not be destroyed under the pavement laying cables, pipelines and other facilities.
