3) the prefabricated sidewall structure part for lifting step 2) keeps prefabricated sidewall structure part pre-buried by upper end with earlier enclosure structure component
Locating piece and the first built-in fitting are located by connecting, prefabricated sidewall structure part and earlier main structure part by the pre-buried locating piece in lower end and
Second built-in fitting is located by connecting；
4) the fixed cast-in-place node template of split bolt is installed on the mounting hole of the pre-buried locating piece in lower end；
5) using prefabricated sidewall structure part and cast-in-place node template as template, in prefabricated sidewall structure part and earlier enclosure structure component
Cast-in-place structural part is poured by cast-in-place mode between earlier main structure part, makes prefabricated sidewall structure part and earlier building enclosure
Part and earlier main structure part form an overall structure；
6) the cast-in-place node template installed on the pre-buried locating piece in lower end is dismantled, that is, completes prefabricated side wall and is located by connecting.
10. the connection method of the prefabricated side wall positioning connection structure of underground structure as claimed in claim 9, it is characterised in that: institute
U-shaped muscle two is reserved in the top for stating earlier main structure part, and U-shaped two both ends of muscle are inserted into earlier main structure part in a manner of U by falling；Institute
Embedded U-shaped muscle one in prefabricated sidewall structure part is stated, prefabricated side wall knot is protruded into from prefabricated sidewall structure part bottom in the side of U-shaped muscle one
In component, the other side is located at outside prefabricated sidewall structure part；When prefabricated sidewall structure part and earlier main structure part are located by connecting,
One bottom of U-shaped muscle of prefabricated sidewall structure part and two exposed portion of the U-shaped muscle dislocation of earlier main structure part are engaged overlap joint, limit
Relative position between prefabricated sidewall structure part and earlier main structure part.
