Railway pier and triangular bracket cross-brace rockfall prevention structure
The invention relates to a railway pier and triangular bracket cross-brace rockfall prevention structure. Triangular supports are arranged on the two sides of a railway beam; each triangular support comprises two inclined rods, the bottom ends of the two inclined rods are fixed to the pier tops of two longitudinally-adjacent railway piers respectively, and the top ends of the two inclined rods intersect and are fixed to the beam bottom of a horizontal longitudinal beam arranged above the triangular supports. A plurality of vertical rods are connected between the horizontal longitudinal beam and the inclined rods of the triangular support, and a vertical protective net is hung between the inclined rods of the triangular supports and the horizontal longitudinal beam. According to the rockfall prevention structure, the middle connecting position of the two triangular supports is located in the midspan of the beam, the supporting force is strong, the stress characteristic of the triangularsupports is equivalent to the fact that the long span of a longitudinal hole is divided into two longitudinal short spans, so that the rigidity of the upper anti-falling stone structure is enhanced,and problems that an ordinary anti-falling stone structure is supported by longitudinal piers, and midspan deflection is large are solved.
本发明涉及一种铁路桥墩加三角支架横撑防落石结构，于铁路梁两侧设置三角形支架，三角形支架包括两根斜杆，两根斜杆的底端分别固定于纵向相邻的两座铁路桥墩的墩顶，顶端相交并固定于三角形支架上方设置的水平纵梁梁底；水平纵梁与三角形支架的斜杆之间连接有多根竖杆，三角形支架的斜杆与水平纵梁之间挂覆有竖向防护网。本发明中，两个三角形支撑的中间连接位置位于梁部跨中，此处支撑力强，三角形支撑的受力特点相当于把纵向一孔长跨分成了两个纵向短跨，上部防落石结构刚度更大，解决了普通防落石结构靠纵向桥墩处支撑，跨中挠度大的问题。
