Embodiment Construction

[0036] The present invention will be described in detail below in combination with specific embodiments.

[0037] The present invention relates to a rockfall prevention structure with triangular brackets and cross braces on railway bridge piers. Triangular brackets 5 are arranged on both sides of railway girders 7. The pier tops of two railway bridge piers 8 intersect and are fixed at the bottom of the horizontal longitudinal beam 6 arranged above the triangular support 5; there are multiple vertical bars 4 connected between the horizontal longitudinal beam 6 and the oblique bars of the triangular support 5, and the triangular support A vertical protective net 3 is hung between the oblique bar of 5 and the horizontal longitudinal beam 6 .

[0038] The horizontal longitudinal beams 6 on both sides are connected by cross braces 2 to form a horizontal connection, and the cross braces 2 are arranged in multiple parallel lines along the line direction. A steel plate 10 is arranged...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of bridge structure construction, and in particular relates to a rockfall-preventing structure of a railway bridge pier plus a triangular bracket cross brace. Background technique [0002] Dangerous rockfall disaster is one of the three major geological disasters in my country. It is a common type of geological disaster in canyon areas and steep mountainous areas. It poses a serious threat to structures and human activities within its hazard range. [0003] my country's high-speed railways are widely distributed, and the completed projects are mainly located in plain areas, but a large number of central and western railways are typical mountainous high-speed railways. High-speed railways in mountainous areas are seriously affected by falling rocks, and there are steep V-shaped ditch areas in mountainous areas. For the project type of high-speed railways in mountainous areas, "two tunnels and one bridge", wit...
