Construction method of self-leveling waterstop for bridge expansion joint
The invention belongs to the field of bridge construction, and particularly relates to a construction method of a self-leveling water-stop belt for a bridge expansion joint, which comprises the following steps of: removing an original water-stop belt in the expansion joint; polishing rust on the side of the profile steel; the supporting piece is pressed into the expansion joint, and the joint between the supporting piece and the profile steel is glued; masking paper is attached to the upper surface of the profile steel; and self-leveling glue is injected into the expansion joint, and the self-leveling glue is solidified to form the self-leveling water stop belt. According to the invention, the construction is simple and convenient, the traffic can be opened after the surface is dried, the road occupation time is less, the difficult problems of rainwater leakage, impurity deposition and the like are completely eradicated, and the novel water-stop belt material which is single-component, self-leveling, easy to construct, environment-friendly, low in modulus, cured at normal temperature, high in elasticity and aging-resistant is adopted, so that the water-stop belt has remarkable advantages in the aspects of construction cost, maintenance cost, service life and the like.
本发明属于桥梁施工领域，具体涉及一种桥梁伸缩缝用自流平止水带施工方法，包括：对伸缩缝中原有止水带进行清除；打磨型钢侧面铁锈；将支撑件压入伸缩缝中，支撑件与型钢接缝处打胶；型钢上表面贴美纹纸；在伸缩缝内打入自流平胶，自流平胶凝固形成自流平止水带。本发明施工简便，表干后即可开放交通，占道时间少，杜绝雨水渗漏、杂物沉积等疑难问题，采用单组分、自流平、易施工、环保型、低模量、常温固化、高弹性耐老化的新型止水带材料，从施工成本、维护成本、使用寿命等方面都有显著优势。
