Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as Figure 1-Figure 4 As shown, the present invention includes a geotextile net combination device arranged directly below the drainage pipe mouth 3, and the geotextile net combination device includes a cylindrical tube 8 and three geotextile net groups (the number of geotextile net groups is not limited to three one, or two or more than three), the cylindrical pipe 8 is arranged directly under the drain pipe mouth 3, and is connected with the drain pipe mouth 3 through a connecting piece. The cylindrical tube 8 is made of PVC material, and the outer wall of the cylindrical tube 8 is 1 / 4 from the upper edge to be provided with four handles 5, and the four handles 5 are evenly arranged along the circumferential direction. The inner wall of the cylindrical tube 8 is provided with a circular groove 12 at 1 / 3, 1 / 2 of the upper edge and the bottom of the inner ...

The invention discloses fabricated bridge drainage outlet ice piton fall prevention equipment. The fabricated bridge drainage outlet ice piton fall prevention equipment is characterized in that the fabricated bridge drainage outlet ice piton fall prevention equipment comprises a geotextile mesh combination device, the geotextile mesh combination device comprises a cylindrical pipe and a pluralityof geotextile meshes, and the geotextile meshes are perpendicular to the axis of the cylindrical pipe and are fixedly mounted in the cylindrical pipe; the pipe opening of the cylindrical pipe is arranged under a drainage pipe opening, and the upper end of the cylindrical pipe is mounted on the drainage pipe opening of a drainage pipe through a connector. According to the fabricated bridge drainageoutlet ice piton fall prevention equipment the geotextile mesh combination device comprises the cylindrical pipe and the geotextile meshes, large ice pitons on the pipe opening are gradually dispersed into small ice pitons through the geotextile meshes, a heating device is arranged on the upper surface of the lowest geotextile mesh, the heating device can melt the small ice pitons, the lowest geotextile mesh can filter water, secondary icing up is prevented, and the fabricated bridge drainage outlet ice piton fall prevention equipment further has the advantages that the structure is simple, the cost is low, and the operation is convenient.
Description
technical field [0001] The invention relates to a prefabricated ice pick anti-dropping device for a bridge drain. Background technique [0002] With the rapid development of the national economy and the strengthening of national power, the bridge engineering in our country has been greatly developed and improved. In order to meet the travel needs of vehicles, relieve traffic pressure, and improve road traffic efficiency, various large and medium-sized bridges have emerged as the times require. But at the same time, a series of problems have also appeared. The expansion joints of the bridge, the edge of the bridge span, and the drainage outlet under the bridge often produce large sharp ice cones below 0°C due to the penetration of rainwater. On the one hand, it affects the beauty of the urban environment. On the other hand, the ice cone is a great safety hazard to pedestrians and vehicles under the bridge during the melting process, and it is easy to cause traffic jams. [...
