Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model colliery surpasses bored grouting fixed point hole sealing device.
Detailed description of the invention
As shown in Figure 1, the utility model colliery surpasses bored grouting fixed point hole sealing device, comprise Grouting Pipe, lead slurry pipe 1, flexible cloth bag 2 and arc annulus 3, flexible cloth bag 2 is fixed in Grouting Pipe by arc annulus 3, and flexible cloth bag 2 is placed in the sealing of hole section of boring A, lead slurry pipe 1 and be set in parallel in Grouting Pipe outside, and the pipe shaft of leading slurry pipe is inserted in flexible cloth bag.Described flexible cloth bag 2 is tubular, and the diameter of cylindrical flexible cloth bag is greater than the diameter of Grouting Pipe, and the two ends arc annulus of flexible cloth bag 2 is fixed in Grouting Pipe, prevents from slidably reciprocating in Grouting Pipe.
Grouting Pipe is used for slip casting, flexible cloth bag 2 is for being fixed the position of Grouting Pipe in boring A, lead slurry pipe 1 for being transported to by sealing material in flexible cloth bag 2, described sealing material adopts inorganic double-liquid seal Porous materials, there is the characteristics such as rapid hardening, early strong, microdilatancy, when sealing material enters into after in flexible cloth bag 2, flexible cloth bag 2 can be made firmly to be fixed in the sealing of hole section of boring by the characteristic of sealing material, the sealing of hole section of described boring comprises aperture sealing of hole section E and middle part sealing of hole section F.
Flexible cloth bag 2 is formed by warp and weft knit, and the pore size between warp and parallel is 0.2 ~ 1mm.If the space between flexible cloth bag 2 warp and parallel is excessive, the situation of Lou material can be caused, if the space between flexible cloth bag warp and parallel is too small, the air produced in sealing material course of conveying can be made to discharge, form bubble and cause the uncompacted situation of filling to occur.
The rubber segments arranged and metal segments is connected before and after Grouting Pipe comprises, the plasma discharge hole 4 that several diameters are 6mm is provided with along its length at rubber segments end, the PE pipe that described rubber segments is one-inch by the long 4m diameter of some joints is connected in series, and adopts pipe collar to connect between adjacent two PE pipes.The seamless coating steel pipe 6 that described metal segments is one-inch by some joints long 2m diameter is connected in series.The quantity of described seamless coating steel pipe 6 is preferably five joints and is connected in series setting.Owing to easily there is spark when touching Grouting Pipe in the process of coal mining cutting coal, cause potential safety hazard, therefore for avoiding this type of situation to occur that Grouting Pipe is positioned at drilling orifice place, this metal segments is set to ensure its intensity, be positioned at drilling hole place in Grouting Pipe and be set to rubber segments, to avoid the generation of spark.
Described leading starches the pvc pipe that pipe 1 is diameter 10mm, and sealing material is transported in flexible cloth bag 2 through leading slurry pipe.To lead on slurry pipe 1 and to be positioned at drilling orifice sealing of hole section E and to be provided with pressure check valve 7, sealing of hole slurries first flow to and are positioned at sealing of hole section F in the middle part of boring A, and when reaching the pressure of setting, pressure check valve 7 is opened, aperture sealing of hole section is full of by sealing of hole slurries, and sealing material completes fixed point sealing of hole after expanding.
