Tenon type connector water-proof structure for side wall of concrete waist beam embedded structure

The invention discloses a tenon type connector water-proof structure for a side wall of a concrete waist beam embedded structure. The tenon type connector water-proof structure comprises a concrete waist beam fixed to the side wall of a foundation pit. The concrete waist beam is embedded in a pouring side wall body and located at the waist of the pouring side wall body. The length direction of the concrete waist beam is consistent with the transverse length direction of the pouring side wall body, and the length of the concrete waist beam is the same as the transverse length of the pouring side wall body. Tenons penetrating through the length of the concrete waist beam are arranged on the upper side and the lower side of the concrete waist beam correspondingly. Water stopping belts are arranged in the tenons. One half of each water stopping belt is fixed in the corresponding tenon, and the other half of each water stopping belt is fixed in the pouring side wall body. Through the structure that the upper tenon
