Description

Technical Field

[0001] The utility model relates to the technical field of base engineering, in particular to a grouting device for foundation engineering. Background Art

[0002] Grouting in construction projects is a method of injecting certain solidifying slurries into cracks or pores in rock foundations by appropriate methods, and improving their physical and mechanical properties through replacement, filling, extrusion, etc. Grouting technology in construction projects can be divided into two categories: static pressure grouting and high-pressure jet grouting. However, according to the mechanism of action of slurry on soil, grouting pressure under geological conditions, movement form of slurry, and substitution methods, grouting technology can be divided into four categories: penetration grouting, splitting grouting, compaction grouting, and jet grouting.

[0003] After searching, application number 202021591765.4 discloses a foundation engineering grouting device, including a base, a mixing barrel and a grouting pipe, the top of the base is fixedly welded with a mixing barrel and a placement rack, and the four corners of the bottom end of the base are equipped with brake universal wheels, the top of the mixing barrel is connected to a feed trough with a feed cover, and the lower half of the mixing barrel is connected to a discharge valve pipe and a drain pipe with a control valve.

[0004] During use, a foundation engineering grouting device in this patent application uses a drilling motor to drive the drill bit to rotate and move the grouting pipe downward to a preset point, and then injects mud into the inner pipe, and pushes the movable valve at the grouting hole on the side of the inner pipe and the movable valve on the side of the outer pipe outward in turn to enter the preset point. However, during such use, when the drilling motor drives the drill bit to rotate and move the grouting pipe downward to the preset point, the movable valve on the outer pipe is buried in the soil at the preset point and is squeezed, which makes it difficult for the mud to push the movable valve on the outer pipe outward to enter the preset point, thereby reducing the practicality of the equipment. For this reason, we propose a foundation engineering grouting device. Utility Model Content
