Abstract
The invention discloses a vertical-drainage type water drain pipe for a bridge and a mounting method for the straight-line water drain pipe. The water drain pipe comprises edge strips and a rubber ring, and further comprises wind boards, wherein the edge strips and the rubber ring can avoid that rainfall on the bridge deck infiltrates in reserved holes of a bridge body; the wind boards can avoid that the water drainage efficiency is reduced in strong-wind weather because the strong wind blows rainwater gathered in the vertical-drainage type water drain pipe and ponding scatters on the bridge deck again. The water drain pipe is simple in structure, convenient to mount, obvious in water drainage effect, and particularly suitable for regions which are high in rain capacity and high in wind speed and have natural freezing and thawing cycles.
Description
The application is that March 1, application number in 2013 are 201310066344.8 the applying date that to be applicant Qingdao Lin Chuan engineering Advisory Co., Ltd submit to State Intellectual Property Office, denomination of invention the dividing an application with the application for a patent for invention of direct-discharging tapping pipe and mounting method thereof that be a kind of bridge.
Technical field
The present invention relates to direct-discharging tapping pipe and mounting method thereof for a kind of bridge, be particularly useful for that amount of precipitation is large, wind speed is high, have the circulate draining of regional bridge floor of nature freeze thawing.
Background technology
Existing bridge construction generally comprises concrete beam and is arranged on the Asphalt Concrete Deck Pavement above concrete beam, for the rainwater on bridge floor being discharged fast to driving region, generally can a tapping pipe be set at a certain distance at bridge lower edge, the installation of tapping pipe is carried out mostly after deck paving completes.
Often there is a bit following or some problem in the mounting method of existing bridge water discharge pipe or tapping pipe:
1, in order to ensure tapping pipe, can install smoothly, the external diameter of tapping pipe is often slightly little compared with the internal diameter of beam body preformed hole, still leaves certain gap after installation between the two; In addition, tapping pipe when mounted, the horn mouth bottom of tapping pipe is not closely sealed with mortar bonding, cause also having penetrating passage between the horn mouth bottom of tapping pipe and beam body end face, rainwater on bridge floor can be by these gaps or the unrestrained bottom that is seeped into beam body frange plate of passage, if things go on like this, can cause that near concrete mortar tapping pipe peels off, aggregate is exposed, corrosion of steel bar, the region that this phenomenon is mingled with deicer salts in bridge floor rainwater more so.
2, tapping pipe is made by PVC or cast iron process conventionally, prolongation along with service time, PVC can become fragile gradually, efflorescence, the continuous corrosion of cast iron meeting, useful area reduces gradually, this will become greatly the gap between tapping pipe and beam body preformed hole gradually, and the amount of rainfall that infiltrates beam body frange plate also can strengthen.
3, for the larger region of wind speed, strong wind can blow afloat the rainwater that imports direct-discharging tapping pipe, and rainwater is scattered on bridge floor again, has reduced the effect of draining and the safety of driving.
As can be seen here, prior art awaits further improving.
