Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Embodiment one, roofing parapet inlet of a river cold bridge structure is prevented, as shown in fig. 1, including roofing bottom plate 2, the parapet 1 of pouring on roofing bottom plate and be located the rainwater fill 3 of the outside of parapet, roofing bottom plate 2 is reinforced concrete structure. The outer side and the inner side of the parapet wall 1 are respectively provided with an outer side heat-insulating layer 5 and an inner side heat-insulating layer 6; a drainage hole is formed in the wall body of the parapet wall 1; the upper end of the rain water bucket 3 is connected with a drainage structure 19, as shown in fig. 2, the drainage structure 19 comprises a drainage pipe 4 and a vertical plate 18 connected with the drainage pipe, and the drainage structure 19 is of a stainless steel structure. The vertical plate 18 is provided with a plate hole 17 matched with the pipe diameter of the drain pipe 4, and the bottom of the vertical plate 18 is fixedly connected with a horizontal plate 8.
