Embodiment Construction

[0020] A static expansion agent sealing device, which includes a bolt 2, a sealing material 1 is fixed on the bolt head of the bolt 2, an expansion sleeve 3 is sleeved on the screw rod of the bolt 2, and the expansion sleeve 3 is fixed by a hex nut 5.

[0021] The length of the expansion sleeve 3 is 0.3-1 meter; when the length is less than 0.3, when the expansion sleeve 3 is expanded by rotating and squeezing the hexagonal nut, the required force will be very large; it is easy to cause the hexagonal nut 5 to slip or be damaged. If the length is too large, after the expansion sleeve 3 is extruded and deformed to seal the hole, due to too little sealing surface, the force of sealing the hole may not be enough, resulting in spray holes.

[0022] The number of the expansion sleeve 3 is at least one section; one end of the first expansion sleeve 3 is fixed on the bolt head of the bolt 2; the other end is fixed by a hex nut 5; each section of the second to the last expansion sleeve ...

Abstract

The invention discloses a static expansive agent hole sealing device and a hole sealing method. The static expansive agent hole sealing device comprises a bolt (2), wherein a sealing material (1) is fixed on a bolt head of the bolt (2), an expandable casing (3) sheathes on a screw of the bolt (2), and the expandable casing (3) is fixed by virtue of a hexagonal nut (5). The hole sealing device and method which are disclosed by the invention have the advantages that operation is simple, effect is obvious, a static expansive agent orifice spraying accident in a construction process can be effectively reduced, and hole sealing quality is improved; and the problems of an existing static expansive agent that an orifice spraying phenomenon extremely easily occurs in the construction process, drop in pressure is caused, and construction and expansion effects are influenced are solved; and the technical problems that construction operation requirement of the static expansive agent is relatively high, potential safety hazard exists in the construction process, and personal damage can be easily caused if operation is irregular, protective measures are not in place and human body is contacted can be solved.

Description

technical field [0001] The invention belongs to the hole sealing technology, in particular to a static expansion agent hole sealing device and a hole sealing method. Background technique [0002] Static expansion agent is widely used in many fields such as material production, silent blasting, transportation, urban construction and industrial and mining enterprises due to its low price, controllable expansion rate and period, no noise and no vibration. However, the static expansion agent is prone to spray holes during the construction process, resulting in a decrease in pressure and affecting the construction expansion effect. The construction operation requirements of static expansion agent are relatively high, and there are potential safety hazards in the construction process. If the operation is not standardized, the protective measures are not in place, and it is easy to cause personal injury if it contacts the human body. At present, there is little research on the exp...
