One is the peeling mechanism for peeling steel cable and collecting the peeled waterproof materials; the other is traveling mechanism which is used to supplement the displacement caused by peeling; the two mechanisms cooperate with each other and maintain the constancy of tension angle.
Therefore, the peeling detector can provide true and reliable quality evaluation data for construction units, to comprehensively improve the construction level and quality of waterproof materials.

Rural energy saving buildings can not blindly applied energy saving technology in city construction, but should select appropriate materials for construction according to the local construction present situation, climatic conditions, economic conditions.
The existing rural roof the roof waterproof layer shall be arranged under the small coefficient of thermal conductivity of the lightweight materials used as insulation.
Send warm pipeline requires the use of thermal insulation material for coating, so as to reduce the heat loss of the pipeline.
Such a large investment will drive the development of wall materials, door and window materials, air-conditioning equipment and other industries, the increase in labor demand, expanding employment opportunities, and promote the sustainable development of local economy and even the national economy.

(II) Material factor Since the civil construction requires various materials in large quantity, and it is really difficult to conduct comprehensive inspection, but it may not be inspected if spot check was taken.
Materials are the material condition of civil construction, while the material quality is the foundation of engineering quality.
Material factor III.
a.Material Preparation and Control; Before material purchase, the suppliers shall be asked to provide test qualification, and test material issued by the detection agency.
Production proportioning; trial mix shall be conducted according to the target proportioning and materials selected, for reaching the feed balance, and then the production proportioning can be determined.
