The invention relates to the technical field of engineering surveying, and particularly relates to an engineering surveying forced centering device and a using method thereof. The engineering surveying forced centering device comprises a base and a mounting part. The base is connected with the mounting part in a nested mode, a stud used for being matched with a threaded hole in a lower end surfaceof a surveying instrument is arranged at an upper end of the mounting part, and the base is used for being fixedly connected with an observation pillar. By using the engineering surveying forced centering device, the base is embedded into the observation pillar in a concrete pouring mode. When measurement is needed, firstly, the mounting part is connected with a lower end surface of the surveyinginstrument through the stud, and then the surveying instrument is fixed through nesting matching between the base and the mounting part so that on one hand, the influence of dust impurities is avoided, and mounting precision
