    產品介紹

        支座灌漿料是一種高性能改性水泥基灌漿材料,采用了多種有機、無機添加劑,具有早強高強、無收縮、耐久性能好等特性。該產品具有很好的施工性能,能夠自流找平,可操作時間長,且完工后表面光滑平整,克服了傳統砂漿所產生的不平整、易開裂、剝落、起粉等缺點,其性能完全滿足《客運專線橋梁盆式橡膠支座暫行技術條件》的要求。

     

    產品特點

       1、微膨脹性能:確保漿料與灌漿部位的牢固粘結,使載荷功能有效地傳遞到基礎。

        2、高流動性能:有很大的流動度,可在不加外力的情況下流向要求灌漿的各個部位。

        3、和易性好:不但流動好而且保持時間長,具有很好的粘聚力,不分層離析,不泌水。

        4、高強度:28天抗壓強度≥50,后期強度高且不倒縮。

        5、低負溫施工:在低溫、負溫下強度仍有較大增長,有效地解決了冬季施工等問題。

        6、耐久性能好:200萬次疲勞試驗,50次凍融循環試驗,強度無明顯變化;抗滲、抗凍、抗腐蝕性能均有良好的表現。

        7、不含氯化物,對設備、鋼筋無任何銹蝕作用。

    產品指標

    適用范圍

        適合于搶修、支座錨固,大型設備和精密設備地腳螺栓與機座的二次灌漿,鋼結構與混凝土固結的二次灌漿,梁、柱二次加固等,特別適用于高速鐵路、客運專線、高速公路橋梁的支座灌漿,其性能指標滿足《客運專線橋梁盆式橡膠支座暫行技術條件》和《客運專線橋梁圓柱面鋼支座暫行技術條件》的技術要求。

    施工工藝

       1、對需灌漿的基面進行鑿毛處理,清除粉塵、油污和其它污垢等不利于粘接的物質;修補裂縫等缺陷;安裝灌漿用模板;用水將支承墊石表面浸濕至飽和,但施工時不得留有明水。

        2、安裝盆式橡膠支座就位,用鋼楔塊楔入支座四角,找平支座,并將支座調整到設計標高,在支座底面與支承墊石之間預留20~30mm的空隙,以便灌漿。

        3、根據施工面積或單位時間施工面積計算粉料量及用水量,每次拌和量應保證在砂漿失去流動性前全部施工完畢。

        4、漿料按粉料:水=1:0.14 (重量比)配制。應先將水加入攪拌桶內,然后逐漸加入稱量好的灌漿料,邊投料邊用電動攪拌槍進行攪拌,直至粉料全部加完,再繼續攪拌3~4分鐘,使漿料均勻。

        5、將拌和后料漿均勻倒于處理好的基面上,自流平即可。采用重力灌漿方式灌注支座底部及錨栓孔處空隙。灌漿過程應從支座中心部位向四周注漿,直至從模板與支座底板周邊間隙處觀察到灌漿材料全部灌滿為止。

        6、流平應在可施工時間內完成,施工后的機具應立即用水沖洗干凈。

        7、灌漿材料終凝后,拆除模板及鋼楔塊,檢查是否有漏漿處,對漏漿處進行補漿,并填堵鋼楔塊抽出后的空隙,擰緊下支座板錨栓。

        8、待灌筑梁體混凝土后,及時拆除上、下支座連接鋼板,并安裝支座鋼圍板。

        9、可施工時間視環境溫度而定,在20℃時為攪拌完成后30分鐘內。
