Anti-seepage drain pipe fitting for bridge

Abstract

The invention discloses an anti-seepage drain pipe fitting for a bridge, and belongs to the field of buildings. The anti-seepage drain pipe fitting for the bridge includes a first connecting pipe, a first filter screen is arranged at the upper end of the first connecting pipe, the first filter screen is clamped with the inner wall of the first connecting pipe, the outer side wall of the first connecting pipe is sleeved with a rubber sealing washer, a plurality of water diversion holes are formed in the side wall of the first connecting pipe, the plurality of water diversion holes are uniformlyformed in the first connecting pipe in a surrounding manner, a sponge block is plugged in each water diversion hole, second filter screens are fixedly connected to the ends, close to the interior ofthe first connecting pipe, of the diversion holes, the sponge blocks are propped against the second filter screens, the lower end of the first connecting pipe is connected with a second connecting pipe and a fourth connecting pipe, the fourth connecting pipe is located on the inner side of the second connecting pipe, a gap is reserved between the fourth connecting pipe and the second connecting pipe, and thread is carved in the outer surface of the second connecting pipe. Water leakage can be reduced through rubber expansion and sponge water absorption performance, and the water drainage effect is good.

Description

technical field [0001] The invention relates to the construction field, in particular to an anti-seepage water drainage pipe fitting for bridges. Background technique [0002] With the development of large-scale highway construction, the number of bridges has increased rapidly, and many problems in the design and construction technology of many bridges have also been exposed. During the bridge inspection, it was found that there was water seepage in a large number of bridge scuppers. In order to quickly discharge the rainwater on the bridge and ensure the safety of vehicles driving in rainy days, a drainage device will be arranged at an interval of about 5m at the position near the anti-collision wall on the lower side of the bridge deck. The construction technology of the drainage device is to reserve the drainage hole when the beam body is poured, and install the drainage pipe fittings at the drainage hole when the bridge pavement is laid after the bridge is completed. ...

AI Technical Summary

Problems solved by technology

[0003] Due to concrete shrinkage and pouring quality during cast-in-place bridge deck pavement, there are gaps between the drainage pipe fittings and the surrounding concrete. As a result, part of the rainwater flows directly to the beam through the gap between the concrete and the drainage pipe fittings during the rainwater drainage process. On the body, the beam body is subjected to rain erosion for a long time, which affects the durability of the beam body
