Zusammenfassung:The invention discloses an angle-adjustable pre-embedded steel bar connector fixing and positioning device and a construction method. The construction method comprises the steps that a belt positioning protection cover with an ejector pin and a positioning chip, a pre-embedded steel bar connector arranged at a control position, a complete pre-embedded steel bar connector positioning design drawing and other positioning technologies are combined; accurate positioning of the pre-embedded steel bar connector is achieved. An angle-adjustable fixing sleeve can be used for quickly and reliably connecting a fixing rib of the pre-embedded steel bar connector with a steel bar of a steel bar cage in a mechanical connection manner, and also realizes the connection between a regular and special-shaped foundation pit engineering underground diaphragm wall and an underground engineering main body structure; according to the positioning information of the pre-embedded steel bar connector, the pre-embedded steel bar connecto
