Problems solved by technology
However, due to the phenomenon of grouting in water-containing loose sand or broken rock, the grout is easy to escape, settle, and segregate, which leads to problems such as low grouting efficiency, shallow grouting depth, and low grouting pressure.

The invention discloses a high-efficiency anti-blocking returnable grouting pipe. The pipe body is spliced and assembled by a plurality of pipe sections; There are multiple intermediate sections connected between the lower end sections. The method of use includes the following steps: use the cooperation between the splicing interface with outer wire and the splicing interface with inner wire to connect the grouting section with the lower end section, start the drill bit to drill, and the middle section will increase synchronously according to the drilling depth; inject grouting into the main pipe When the grout reaches a certain pressure, the pressure-resistant rubber sleeve will open, and the grout will flow out from the grout outlet to the grouting area; The main pipe enters the grouting section, goes up to the upper end section under pressure, and flows out from the return outlet. The invention has the advantages of simple structure and convenient operation, and can solve the problems of grout escape, sedimentation, segregation and the like during grouting of the existing grouting pipe, and greatly improves the grouting efficiency.
Description
technical field [0001] The invention relates to a grouting pipe and a method, in particular to a high-efficiency anti-blocking reflowable grouting pipe and a method. Background technique [0002] Grouting is divided into ceramic craft grouting and construction engineering grouting. Ceramic technology grouting is a process of injecting prepared mud into ceramic production. Construction engineering is a method of injecting some curable grout into the cracks or pores of rock foundations with appropriate methods, and improving its physical and mechanical properties by means of replacement, filling, extrusion, etc. However, due to the phenomenon of grouting in water-containing loose sand or broken rock, the grout is easy to escape, settle, and segregate, which leads to problems such as low grouting efficiency, shallow grouting depth, and low grouting pressure. Contents of the invention [0003] In order to solve the shortcomings of the above-mentioned technologies, the presen...
