Line pipe pre-embedded structure

The invention discloses a line pipe pre-embedded structure which comprises a plurality of pre-embedded assemblies, the multiple pre-embedded assemblies are sequentially connected in a threaded mode, each pre-embedded assembly comprises a corrugated pipe, a first internal thread pipe body and a fixing mechanism, external thread pipes are arranged at the two ends of each corrugated pipe respectively, and the corrugated pipes are sequentially arranged on the same central axis; the inner wall of the first internal thread pipe body is in threaded connection with the inner wall of the corresponding external thread pipe; the fixing mechanism comprises a second internal thread pipe body, a fixing support and a plurality of fixing rings; therefore, the metal wire pipe can be prevented from being bent difficultly, the construction speed is increased, meanwhile, formwork holing is avoided, the formwork turnover rate is increased, it is guaranteed that the embedded wire pipe is damaged due to misoperation in the formwork
