The invention discloses an underground connecting pile wall for a shallow foundation pit support structure and a construction method of the underground connecting pile wall. The construction method comprises the following steps that S1, a guide wall is constructed along the periphery of a foundation pit; according to the construction method, continuous grooving is conducted on the outer side of the foundation pit of the accessory structure of the subway station, in the grooving process, the perpendicularity of a groove section can be observed in real time through an instrument panel of the grooving machine, correction is conducted in time, and the grooving perpendicularity is high; after grooving is finished, perpendicularity detection is conducted through ultrasonic waves, and guarantee is provided for installation of the reinforcement cage; the groove sections are engaged through the lock catch pipe joints, the wall of the joints is brushed before the reinforcement cage is installed on the subsequent groove
