1) by the outer surface covering insulation material of single hole box beam；
2) at the reserved location that several electric heaters are uniformly placed on inside single hole box beam；
If 3) build dried layer masonry by laying bricks or stones at the two ends hole of single hole box beam；
4) in single hole box beam internal water flooding；
5) open the switch of electric heater.
Further, the step 1) in insulation material include geotextiles and cotton-wool blanket, the cotton-wool blanket is job site
It is a kind of image address, due to being that cotton-wool is layered on box beam surface, be commonly called as cotton-wool blanket.
Further, the step 2) in electric heater between serial or parallel connection, and the switch of electric heater be located at box beam outside.
Of the present utility model to have the technical effect that mathematical, this utility model is realized using insulation materials such as geotextiles
The continuous heating that electric heater realizes inside is placed in the external insulation of box beam, the rational space using inside box beam.It is relatively more existing
The Heat preservation technology of some prefabricated case beams, this utility model tiger head advantages below：
1), using electric heater general on market, purchase is convenient, and equipment safety is guaranteed for this utility model；
2) this utility model is adopted geotextiles and electric heater low cost, while can reuse, improve resource profit
With rate；
3) this utility model can select appropriate number of electric heater according to the size of box beam span, be easy to live behaviour
Make, save manpower, improve productivity effect；
4) this utility model reasonably make use of the space inside box beam, and the masonry built by laying bricks or stones temporarily ensures inside box beam all the time
Moistening, provides suitable environment to the condensation hardening of concrete；
5) this utility model is capable of achieving heating and is incubated to carry out simultaneously, concrete can be caused to ensure in higher temperature and steady
It is fixed, improve the maintenance quality of box beam.
