Problems solved by technology

During high-pressure grouting, the friction force is often unable to resist the grouting pressure, resulting in the failure of the grouting pipe to close; when the quick-setting cement is injected, the gap is easily blocked by the condensed cement, and the grout stopper cannot be moved. Therefore, we propose a A grouting hole segmentation device based on electromagnetic sealing to solve this problem

Abstract

The invention discloses a grouting hole sectioning device based on electromagnetic sealing. The grouting hole sectioning device comprises a grouting pipe and is characterized in that a plurality of grouting hole sectioning film bag internal patterned holes are arranged in the grouting pipe in an equal-distance manner, grouting hole sectioning film bags sleeve the grouting pipe parts outside the grouting hole sectioning film bag internal patterned holes, a grouting pipe fixed-pressure film is arranged between one sides, close to each other, of every two adjacent grouting hole sectioning film bags, stratum grouting patterned holes are arranged below the grouting pipe fixed-pressure films, an electromagnetic grout stopper guide rod is arranged at the bottoms of the stratum grouting patternedholes, and an electromagnetic grout stopper is fixed to one end of the electromagnetic grout stopper guide rod and located in the grouting pipe. The grouting hole sectioning device has the advantagesthat the device is provided with the electromagnetic grout stopper, the spread electromagnetic grout stopper can tightly attach to the grouting pipe, generated friction force can resist high groutingpressure, a large gap can be kept between the contracted electromagnetic grout stopper and the grouting pipe to facilitate vertical movement, application cost is lowered, grout reaction speed is increased, and the device is convenient to use and suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of grouting holes, in particular to a segmented device for grouting holes based on electromagnetic sealing. Background technique [0002] At present, one of the cores of the subsection in the grouting hole is the grout stopper in the grouting pipe, and the other is the separation device between the grouting pipe and the grouting hole. Both the stop plug and the partition device are involved in the existing device, but the specific structure of the stop plug is not mentioned. The diameter of conventional rubber and mechanical grout stoppers is close to the diameter of the grouting hole. The grouting pipe is sealed by friction force generated by rubber deformation, and the gap is formed by rubber rebound deformation to provide conditions for the grout stopper to move. During high-pressure grouting, the friction force is often unable to resist the grouting pressure, resulting in the failure of the grouting pip...
