Embodiment 1

[0029] see Figure 5 , a bridge drainage pipe provided in the figure, including a horizontal pipe 100, an elbow joint 200 and an inclined pipe 300, one end of the horizontal pipe 100 is fixedly connected with the elbow joint 200, and the other end of the horizontal pipe 100 is a water inlet 110; the elbow joint The other end of the 200 is fixedly connected to one end of the inclined pipe 300 , and the other end of the inclined pipe 300 is a water discharge port 310 . The internal angle α of the elbow head 200 is designed to be greater than 0° but less than 90° or less than or equal to 90°, preferably 70° to 80°, so that the center axis 111 of the water inlet 110 of the horizontal pipe 100 and the middle of the water outlet 310 The angle β between the axes 311 is greater than 0° but less than 90° or less than or equal to 90°, preferably 70°-80°, which solves the problem of the inclined pipe draining beyond the red line in the prior art.

Embodiment 2

[0031] see Figure 6 , a bridge drainage pipe shown in the figure, which includes a horizontal pipe section 400, an elbow section 500 and an inclined pipe section 600, and the horizontal pipe section 400, the curved pipe section 500 and the inclined pipe section 600 are sequentially continuous into an integral structure, that is, the horizontal pipe section 400 , The curved pipe section 500 and the inclined pipe section 600 are formed by one-time injection or casting; the internal angle γ of the curved pipe section 500 is designed to be greater than 0° but less than 90° or less than or equal to 90°, and the internal angle γ is preferably 70° ~80°, so that the central axis 411 of the water inlet 410 of the horizontal pipe section 400 and the central axis 611 of the discharge port 610 of the inclined pipe section 600 form an angle greater than 0° but less than 90° or less than or equal to 90° R, the included angle R is preferably 70°-80°, which solves the problem of the inclined...

Abstract

The invention discloses a bridge drain bent pipe comprising at least one water inlet and at least one water outlet communicated with the water inlet. The bridge drain bent pipe is characterized in that an inclined angle between the central axis of the water inlet and that of the water outlet is larger than 0 degree and less than or equal to 90 degrees. Since the inclined angle between the central axis of the water inlet and that of the water outlet is larger than 0 degree and less than or equal to 90 degrees, water drained from the water outlet flows along the spanning outer side face of a side plate, and can be prevented from draining outside a red line of a bridge, accordingly disputes caused by draining between a bridge construction unit or bridge management unit and villagers can be avoided, and farmlands or corps in mountain land can be prevented from damaging.

Description

technical field [0001] The invention relates to the technical field of drainage pipes, in particular to a bridge drainage elbow. Background technique [0002] Such as figure 1 As shown, the bridge used in the current bridge is completely drained, and it includes a horizontal pipe 6, an elbow joint 7 and an inclined pipe 9, and one end of the cross pipe 6 is fixedly connected with the elbow joint 7 (the ones made of plastic materials are generally glued) , made of metal materials are generally threaded), the other end of the elbow 7 is fixedly connected with the inclined pipe 8, and the elbow 7 is an elbow with an angle R of about 110°; this kind of bridge drainage elbow has the following aspects question: [0003] 1. This kind of bridge elbow is composed of three parts, which need to be processed separately by injection molding or casting (plastic pipes are injection molding, metal pipes are casting), and the processing is complicated. If the metal pipes need to be process...
