According to various studies, in this bridge project to make isoacid vinegar and polyol polymerization reaction, the formation of flexible chemical composition of 995 structural adhesive, and before the start of the project, according to the specific requirements of the selection of construction materials in line with the engineering standards. When the two-component polyurethane sealant material is selected for site construction, the ambient temperature must not be lower than 100C within 1d time before the project starts and after completion, otherwise the material cannot play its normal performance, but the ambient temperature should be lower than 50C'" in the irrigation construction.

        For the construction environment in the project can not meet the above requirements, it is necessary to take the necessary anti-freezing measures to improve the performance. The construction is carried out in strict accordance with the design scheme and construction technology. The construction process mainly includes the following aspects:

        (1) Before the construction starts, the location of the expansion joint should be checked. If there are impurities, it needs to be cleaned up in time to avoid affecting the smooth implementation of the project due to these substances, and then the transparent tape is pasted on the expansion joint steel, so as to effectively avoid the pollution of impurities and affect the quality.

        (2) According to the technical parameters in the design scheme, the isoacid vinegar and polyol poly mix fully, so as to form the two-component polyurethane sealant material needed in the project.

        (3) The height of the section steel slightly higher than the expansion joint scraping construction materials.

        (4) Tear the tape on the surface of the section steel. All the sealant must be completely solidified before it can be opened to traffic, otherwise it will affect the quality of the expansion joint.
