Formula is fixedly connected with pipe main body 110, and pipe main body 110 here is made of the stainless steel or iron sheet of 0.8-1.4mm, Ke Yizeng
Transmission efficiency of the heat into pipe main body 110 inside strong coagulation body, further, the inner and outer wall of pipe main body 110 is uniform
It is arranged several raised 112.
It should be noted that pipe main body 110 is arranged to above-mentioned relatively thin side wall, is made in order to enhance the effect of heat transmitting
Its bearing capacity ratio is lower, so being used as stress main body in four angles of pipe main body 110 setting reinforcing prop 111, both met to mixed
The cooling demand of soil is coagulated, and meets the requirement of bearing capacity.And the present apparatus is finishing concrete cooling and is reaching certain age
Later, it needs to inject fines concrete or mortar into cooling tube 11 and rhone 31, wraps up all metal materials
In the corrosion in concrete, avoiding generating cooling tube 11, and the corrosion is transferred on the reinforcing bar of concrete structure, and influences knot
The stability of structure and service life.
In addition, since pipe main body 110 is arranged to undaform or broken line type, and the inner and outer wall of pipe main body 110 is uniform
It is arranged several raised 112, after injecting mortar or fines concrete into cooling tube 11, pipe main body 110 can make its inside
Mortar and external concrete are combined into an entirety well.
Shown in referring to figure 2., in alternative embodiment of the invention, the top of cooling tube 11 is connected with Grouting Pipe 113, note
Slurry pipe 113 is for injecting mortar into cooling tube 11, and Grouting Pipe 113 is for removably installing top insulating layer.Each cooling
The top of pipe 11 is provided with Grouting Pipe 113, it is ensured that every cooling tube 11 can be filled with mortar after use finishes
Or concrete.
As described above, one of them is to inject mortar or particulate into cooling tube 11 there are two the effects of Grouting Pipe 113
Concrete, another effect is for hanging insulating layer.The reason is that, concrete generates the reason of crack, it is inside and outside
Excessive temperature differentials so that concrete deformed during condensation it is inconsistent, to generate crack.Insulating layer is arranged in the present apparatus,
Especially during the broiling summer, insulating layer can prevent being exposed to the sun for the sun, then avoid the excessive evaporation of moisture, can equally prevent
The only generation of surface crack.Using the measure of " protecting outside interior drop " in the present embodiment, concrete can be effectively prevented in condensation process
It is middle to generate crack because internal-external temperature difference is excessive.
