Abstract

The invention discloses a steel flower pipe segmented grouting system, which comprises a spiral rubber sleeve steel flower pipe and a matched telescopic grouting gun head, wherein the telescopic grouting gun head is connected with an intelligent data recording instrument through a grouting pipe, the other end of the intelligent data recording instrument is connected with a grouting slurry inlet opening, the spiral rubber sleeve steel flower pipe comprises a steel flower pipe, the bottom of the steel flower pipe is sequentially provided with a steel flower pipe sealing bottom plate and a U-shaped support frame which are mutually matched, a plurality of spirally distributed grouting holes are formed in the pipe body of the steel flower pipe, and a spiral rubber sleeve in spiral matching is fixedly arranged on the grouting hole through a plurality of steel wires, the telescopic grouting gun head comprises a grouting gun head shaft rod, one end of the grouting gun head shaft rod is movably connected with an upper slurry stop plug, and meanwhile, the other end of the grouting gun head shaft rod is fixedly connected with a lower slurry stop plug.

Description

technical field [0001] The invention relates to the field of geotechnical engineering grouting reinforcement, in particular to a segmental grouting system for steel pipes and a construction method thereof. Background technique [0002] At present, in the field of grouting reinforcement in geotechnical engineering, as a new foundation reinforcement and support measure, grouted steel pipe is especially suitable for rapid support of foundation pits, engineering rescue and advanced support projects. Because the grouting effect is greatly affected by the formation conditions, it is difficult to ensure the grouting effect and the reliability of the support structure for complex formations. Segmented grouting provides the possibility to improve the grouting effect. In view of the layered distribution characteristics of the stratum, the grouting gun head with variable length and the helical drilling with uniform distribution of the length of the grouting section of the steel flower ...
