Quick drainage mechanism for river-crossing bridge deck slope

Abstract

The invention relates to the technical field of bridge design, and discloses a river-crossing bridge deck side slope quick drainage mechanism which comprises a bridge deck, a side slope arranged on one side of the bridge deck, a bridge foundation arranged on one side of the side slope, a coarse filter screen arranged at one end of the side slope, an underground pipeline arranged at one end of the coarse filter screen and a transfer water tank arranged on one side of the underground pipeline. A fine filter screen is arranged at the bottom of the transfer water tank; a stirring mechanism is arranged at the bottom of the fine filter screen; a longitudinal drainage ditch is formed in the bottom of the stirring mechanism; a drainage pipe is arranged at the periphery of the longitudinal drainage ditch; according to the quick drainage mechanism for the river-crossing bridge deck slope, the slope is arranged to increase the drainage amount and avoid a large amount of accumulated water on a bridge deck, the drainage efficiency is improved by arranging double-layer filtering, water flowing is accelerated by arranging the stirring mechanism, blockage is avoided, buffering and damping are effectively conducted by arranging the outer pipe, and the inner pipe is prevented from being damaged by impact and extrusion.

Description

technical field [0001] The invention relates to the technical field of bridge design, in particular to a rapid drainage mechanism for the side slope of a river-crossing bridge deck. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. There is also a drainage structure installed on the bridge surface; using the drainage structure to drain the accumulated water or rainwater on the bridge surface, on the one hand, it reduces the probability of vehicle skidding, and on the other hand, it can also prolong the service life of the bridge. Therefore, the bridge surface The drainage structure is very important. [0003] Slope refers to the slope with a certain slope made on both sides of the roadbed in order to ensure the stability of the roadbed. At present, it can be classified according to the cause: it can be divided into artificial slope and natural slope; according to the stra...

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a rapid drainage mechanism for the slope of the bridge deck across the river. The device collects the rainwater in time by setting the water collection channel, which can solve the problem of rapid drainage of the slope of the existing bridge deck across the river. During the period of strong storm and rain, the amount of rainwater is large and the flow velocity is fast, causing a large amount of rainwater to accumulate on the bridge deck, resulting in poor drainage of the bridge deck and affecting the safety of driving on the bridge deck; by setting a double-layer filter structure coarse filter and fine filter to improve filtration The effect improves the drainage efficiency, and the water flow is accelerated by setting the stirring mechanism to avoid clogging. The outer pipe is installed outside the drain pipe to effectively buffer and absorb shocks, preventing the inner pipe from being washed and squeezed. Causes a large impact, causing the branch pipe to shake, causing the connection between the branch pipe and the main pipe to be easily broken or damaged
