Telescopic floral tube grouting pipe

Abstract

The invention discloses a telescopic floral tube grouting pipe which comprises an outer grouting pipe, an inner grouting pipe, an outer grouting pipe conical plug, an inner grouting pipe circular plug and a hemispherical cover bowl; a circular cover plate used for plugging is arranged at the upper end of the outer grouting pipe; the hemispherical cover bowl used for slurry sealing and positioning is arranged at the upper end of the inner grouting pipe; an inner grouting pipe outer wire is arranged on the outer wall of the top end of the inner grouting pipe; an inner grouting pipe inner wire is arranged on the inner wall of the bottom end of the inner grouting pipe; a circular plug outer wire matched with the inner grouting pipe inner wire is arranged at the upper end of the inner grouting pipe circular plug; an outer grouting pipe inner wire is arranged on the inner wall of the bottom end of the outer grouting pipe; a conical plug outer wire matched with the outer grouting pipe inner wire is arranged at the upper end of the outer grouting pipe conical plug; and a horizontal grouting hole set and an inclined grouting hole set are arranged on the outer wall of the inner grouting pipe at intervals. Compared with the prior art, the telescopic floral tube grouting pipe has the advantages that the effective grouting range of an existing grouting technology is widened and improved, and the grouting reinforcement effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a telescopic flower pipe grouting pipe. Background technique [0002] The grouting technology is to prepare a certain material into a slurry, and pour it into the formation or gaps with pressure feeding equipment to make it diffuse, gel or solidify, so as to achieve the purpose of strengthening the formation or preventing seepage and plugging. It can be used for anti-seepage and plugging, improving the strength and deformation modulus of foundation soil, filling voids, reinforcing existing building foundations and controlling deformation. [0003] Existing grouting-related pressure-feeding grouting equipment has no specific grouting head, and mostly uses grouting pipes and movable plugs as the grouting terminal. In the actual grouting process, the grout only radiates and diffuses in one plane, and the grouting direction is single The repeated intersection surfac...

[0003] Existing grouting-related pressure-feeding grouting equipment has no specific grouting head, and mostly uses grouting pipes and movable plugs as the grouting terminal. In the actual grouting process, the grout only radiates and diffuses in one plane, and the grouting direction is single The repeated intersection surface of the upper and lower layers is uneven, which indirectly affects the overall effect of grouting
