Underground station surrounding stratum consolidation anti-settlement method
The invention provides an underground station surrounding stratum consolidation anti-settlement method. The method comprises the following steps that (1) a movable Cacl2 solution tank and a water suction pump are arranged in an underground station, and a bacteria and urea transport vehicle is arranged on the ground; (2) a first liquid conveying pipeline is connected to the water suction pump, a second liquid conveying pipeline is arranged on the bacteria and urea transport vehicle, and the first liquid conveying pipeline and the second liquid conveying pipeline are led into the stratum; (3) a pressure regulating valve and a pressure gauge are mounted on the first liquid conveying pipeline; (4) the water suction pump is started to convey a Cacl2 solution to the stratum, and the bacteria and urea transport vehicle is started to convey bacteria and urea to the stratum; (5) a pressure regulating valve is adjusted to enable the reaction dose of the Cacl2 solution to be consistent with the reaction dose of the bacteria and the urea; and (6) the solution reacts in the stratum to generate CaCO3. According to the method, the Cacl2 solution, the bacteria and the urea are respectively conveyed to the stratum, so that the Cacl2 solution, the bacteria and the urea react in the stratum to generate CaCO3 to consolidate the stratum, the problem of settlement of the stratum around the underground station of the stratum is effectively solved, and meanwhile, the environment is prevented from being polluted.
本发明提供了一种地下车站周边地层固结防沉降方法，包括如下步骤：(1)在地下车站内设置移动式Cacl2溶液箱和抽水泵；在地面上设置细菌及尿素运输车；(2)在抽水泵上连接第一输液管道，在细菌及尿素运输车上设置第二输液管道，并将第一输液管道、第二输液管道分别通入地层中；(3)在第一输液管道上安装调压阀与压力表；(4)开启抽水泵为地层输送Cacl2溶液，开启细菌及尿素运输车为地层输送细菌、尿素；(5)调节调压阀，使Cacl2溶液与细菌与尿素反应量一致；(6)溶液在地层中反应，生成CaCO3。本发明通过向地层分别输送Cacl2溶液与细菌、尿素，使其在地层中反应生成CaCO3固结地层，有效的解决了地层地下车站周边地层的沉降问题，同时保证了环境未受到污染。
