Deep sealing type hole sealing device and hole sealing method

Abstract

The invention provides a deep sealing type hole sealing device which can solve the technical problem that a traditional hole sealing device is complex in process and cumbersome in operation. The deep sealing type hole sealing device comprises a suction pipe and a grouting pipe, wherein the suction pipe and the grouting pipe are arranged in parallel, two sealed bags are arranged at the two ends of a hole sealing segment of the suction pipe and the grouting pipe respectively, the bag close to a hole opening is a hole opening bag, the bag close to a hole bottom is a hole bottom bag, the bags wrap the suction pipe and the grouting pipe, the tail end of the grouting pipe is sealed and arranged at the bottom of the hole bottom bag, a one-way valve is arranged at the position, in the corresponding bag, of the grouting pipe, and an explosion valve is arranged between the two bags. The deep sealing type hole sealing device further comprises a floral pipe, wherein the floral pipe is provided with a plurality of notches, one end of the floral pipe is fixed to the outer portion of the bottom of the hole bottom bag, a sharp cone is arranged at the other end of the floral pipe, the tail end of the suction pipe stretches out of the bottom of the hole bottom bag to be connected into the notches of the floral pipe, and the end, close to the hole bottom, of the suction pipe is provided with a plurality of holes. According to the deep sealing type hole sealing device, casing installation, hole sealing and drainage are integrated, so that convenience is achieved, and operation procedures are reduced.

Description

technical field [0001] The invention relates to the field of sealing various drainage drilling holes in mines, in particular to a deep sealing type hole sealing device and a hole sealing method. Background technique [0002] Due to the loose ring and fissure zone formed in the roadway from the rock (coal) wall inward during the construction process of developing and constructing the roadway, the sealing principle of ordinary sealing products is to use "two blocks and one injection" to seal the hole from the hole inward , The length of the sealing hole is determined by the scope of the fissure zone in the surrounding rock and the requirements of the technical measures of the mine. When the surrounding rock of the roadway is loose or the fissure zone is seriously developed, the roadway needs to be sprayed, grouted and other sealing measures before sealing the hole. Ordinary sealing products need to be used in conjunction with PVC gas drainage pipes to extract gas, and the PVC ...
