Description
Technical field
The present invention relates to technical field of drainage, and in particular to defroster is used in a kind of draining.
Background technique
As China squeezes out the development of facility, the investment of bridge and tunnel in transport development is more and more.Draining
The installation of pipe and bridge is also in rising trend.
The existing bridge and the drainpipe in tunnel of being installed on is usually pvc pipe or bellows and metal tube, the above pipe
Road is all the single pipeline of structure, and carrying out blowdown draining at normal temperature can be very well, but in cold winter, especially northeast
The winter in area, outdoor temperature are extremely low.Remaining water can freeze because outdoor temperature is low in drainage pipeline, or even by drainpipe
Road blocking, so that the ponding on bridge can not drain, to cause safety accident.In order to avoid the generation of safety accident, usually
The personnel that can arrange work dredge these drainpipes, on the one hand the personnel that arrange work, which carry out drain pipe-dredging, can waste many
Labour will receive certain influence to the purge operation of the pipelines such as bridge, be also possible to simultaneously on the other hand in cold winter
Security threat is brought to staff.Therefore, existing solution and undesirable.
In order to reduce the workload of staff, and drainpipe is improved in the drainage effect in winter, reduce each of initiation
Kind safety problem, therefore it is badly in need of a kind of draining defroster, blocking is frozen to avoid drainpipe.
Summary of the invention
The purpose of the present invention is to provide a kind of draining defrosters, to solve to be easy quilt in cold winter drainpipe
The problem of frost blocking.
In order to achieve the above objectives, the technical scheme is that a kind of draining defroster, including drainpipe, draining
