Intubating grouting base of transmission line iron tower

The utility model provides an intubating grouting base of a transmission line iron tower, which comprises a bearing platform arranged at the upper part and a perforated steel pipe arranged at the lower part of the bearing platform. The intubating grouting base consists of the upper bearing platform and the lower perforated steel pipe. The perforated steel pipe at the periphery is inserted into the sand soil, the fully-weathered rock or the compact strongly-weathered rock, the spread slurry is condensed with the peripheral rock soil into a pile body similar to the concrete by means of pressure grouting of the steel pipe, and the perforated steel pipe and the bearing platform jointly bear the basic acting force transferred by the iron tower in the condensed pile body similar to the concrete, so that the intubating grouting base has better upward-pull load and downward-press load resistance. The bearing platform of the intubating grouting base is shallowly embedded. Compared with a digging base, the work load of
