Water and land combined construction method for bridge pile foundation protection through slurry solidified soil
The invention discloses a water and land combined construction method for bridge pile foundation protection through slurry solidified soil. The water and land combined construction method comprises the steps that S1, slurry solidified soil slurry is prepared on the land; s2, transporting the slurry solidified soil slurry to a construction point on a bridge floor by using a transportation tank truck; s3, the unpowered positioning ship is anchored and positioned near the to-be-reinforced bridge pile foundation; s4, the transportation tank car is connected with the unpowered positioning ship through a pipeline; and S5, the slurry solidified soil slurry is pumped into an underwater scouring pit of the bridge pile foundation through a conveying pipeline of the unpowered positioning ship. According to the land and water combined construction method, the mode that land transportation and water ship pumping are combined is adopted, the construction efficiency is remarkably improved, the construction effect is better than that of a traditional riprap technology, the protective filling face is smooth, secondary washing can be effectively prevented, the loss rate of solidified soil slurry in the construction process is low and is controlled to be about 20% and not larger than 25%, and the construction period is shortened. The construction cost is reduced.
本发明公开了一种泥浆固化土用于桥梁桩基防护的水陆结合施工方法，其包括有：步骤S1、在陆地上制备泥浆固化土浆液；步骤S2、利用运输罐车运输所述泥浆固化土浆液至桥面上的施工点位；步骤S3、将无动力定位船抛锚定位于待加固桥梁桩基的附近；步骤S4、将所述运输罐车与所述无动力定位船通过管道连接；步骤S5、通过所述无动力定位船的输送管道泵送所述泥浆固化土浆液至桥梁桩基水下的冲刷坑内。该水陆结合施工方法采用陆上运输与水上船舶泵送相结合的方式，显著提升了施工效率，施工效果优于传统的抛石工艺，其防护填充的面比较平整，可有效防止二次淘刷，施工过程中的固化土泥浆流失率低，控制在20％左右，不超25％，减少施工成本。
