The invention relates to a diaphragm wall joint flexible water stop installing device and a method. The installing device is a connector pipe structure made of steel plates or profile steel with width-thickness ratio being close to 1, at least one mounting groove capable of installing a rubber water stop is arranged on one side of the installing device in contact with concrete, and the width at an opening of the mounting groove is slightly smaller than that of a groove cavity. Since the width-thickness ratio of the connector pipe is close to 1, one side of the connector pipe in contact with soil is closely stuck with a soil layer, no phenomenon of flow around exists during the concrete pouring process, the subsequent construction of the groove section is greatly facilitated, and the installing device and the installing method have the advantages of the round pipe connector and overcome the defects of the I-shaped steel connector; the installation and the disassembly are convenient; the connection of the connector pipes is reliable, and the installing device and the installing method have sufficient rigidity, further meet the requirements for deformation resistance and connection and provide convenience for lifting the connector pipe; and the installed rubber water stop has good effect, does not drop off, can be completely retained on a concrete interface, and can well be adapted for the deformation caused by long-term dynamic load in the soft soil strata and prevent the seam from leaking due to misplacement.
