Abstract
The utility model relates to the field of safety control, particularly to a rapid plugging device. The rapid plugging device is applicable to fixing plugging materials of two components which can complete reaction within seconds after being blended. The rapid plugging device comprises a grouting pump, an external pipe and an internal pipe inside the external pipe, wherein the outlet of the grouting pump is connected with the external pipe, and the outlet of a gelling agent feeding pump is connected with the internal pipe, and the outlet end of the inner pipe is arranged inside the external pipe. The rapid plugging device is mainly applied to plugging of specific areas such as roadways or goaves of mines and meanwhile can be applied to plugging of areas where people cannot reach easily.
Description
Technical field
The utility model relates to safe prevention field, and specifically a kind of fast plugging device that is applicable to two fast component plugging materials of setting rate is specially adapted to be difficult to personnel such as mine laneway goaf the isolation shutoff of the specific region arriving.
Background technology
At present, the method for mine laneway and goaf shutoff is had a variety of, for example: expanded material shutoff, grout sealing, gel shutoff and colloid shutoff etc.The plugging material of gel shutoff and colloid shutoff is mainly made up of two kinds of components, wherein a kind of component is cementitious material, its method for blocking is to be injected into shutoff district by pump and pipeline after two component materials are mixed, plugging material loses flowability gradually and solidifies subsequently, and this is also the normal method adopting in coal-mine fire control in recent years, goaf filling.At present, while adopting two component materials to realize method for blocking, its two component materials mixed before entering pipeline, and this is very convenient in construction, but just inadaptable for the material that need to react within the several seconds.Conventionally have a segment distance because be mixed into outlet from bi-material, the material that reacts too fast is understood fast reaction and solidifies in pipeline.In addition, also there will be the abnormal phenomenon of equipment operation in work progress, once it is undesired to turn round, the material that reacts too fast also can be set in pipeline, even has the danger that damages the pump housing, pipeline, and then also can threaten to personal safety.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of fast plugging device applicable to complete two component plugging materials of reaction after mixing within very short time.
The technical scheme that the utility model addresses the above problem is: the fast plugging device providing comprises grouting pump, gelling agent interpolation pump, Outer Tube and is placed in the interior conduit of Outer Tube, wherein slip casting delivery side of pump is connected with Outer Tube, gelling agent adds delivery side of pump and is connected with interior conduit, and the port of export of interior conduit is in Outer Tube.When shutoff, first drill to and need the region of shutoff with hollow drill pipe, complete this hollow drill pipe of drilling, as the Outer Tube of plugging device, is connected with slip casting delivery side of pump, also can replace hollow drill pipe to be used as Outer Tube with mining sleeve pipe; Then interior conduit is placed in Outer Tube, draw from Outer Tube sidewall one end of interior conduit, and add delivery side of pump with gelling agent and be connected, thus a fast plugging device of composition.The slurries that prepare enter Outer Tube by grouting pump, and gelling agent adds pump by gelling agent and enters interior conduit, enters Outer Tube from the interior conduit port of export, mixes with slurries, is re-introduced into shutoff region.
For the gelling agent that makes interior conduit can mix with the slurries of Outer Tube better, can plug be set at the port of export of interior conduit, plug is provided with multiple through holes, and gelling agent, by the through hole ejection on plug, can mix with the slurries of Outer Tube equably.
The port of export of above-mentioned interior conduit is arranged near the port of export of Outer Tube, and generally, the distance of the interior conduit port of export and the Outer Tube port of export is 0.2 meter～1 meter, and scheme is that the distance of the interior conduit port of export and the Outer Tube port of export is 0.2 meter～0.5 meter preferably.
Above-mentioned grouting pump and gelling agent add pump and all adopt Flow-rate adjustment pump, to control setting rate by the flow proportional that regulates slurries and gelling agent.
The utility model is simple in structure, and operation is succinct, and the two component plugging materials that particularly suitable solidifies rapidly after mixing especially have superior effect in the time solving the quick blocking of mine laneway or specific region, goaf.Owing to being provided with inside and outside pipeline, two components of plugging material can not be mixed in carrying at a distance, but just mix near the outlet of conveyance conduit, thereby can not stop up transfer pipeline and pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model interior conduit plug.
The specific embodiment
As shown in Figure 1 and Figure 2: the interior conduit 4 that fast plugging device mainly adds pump 2, Outer Tube 3 by grouting pump 1, gelling agent and is placed in Outer Tube forms, wherein the outlet of grouting pump 1 is connected with Outer Tube 3, and the entrance point of interior conduit 4 is connected with the outlet of gelling agent interpolation pump 2 from a side of Outer Tube is drawn.Be provided with plug 5 at interior conduit 4 ports of export, which is provided with through hole 6(referring to Fig. 2), in fact plug 5 can be the form of porous plate.
Embodiment 1
First with rig, hollow drill pipe is drilled into the assigned address that needs shutoff, is then connected with grouting pump 1 this hollow drill pipe as Outer Tube; If hollow drill pipe internal diameter is too small, take out drilling rod, the sleeve pipe larger with internal diameter is connected with grouting pump 1 as Outer Tube 3, is deep into the assigned address that needs shutoff by boring.Interior conduit 4 is placed in Outer Tube 3, and its one end is added pump 2 with gelling agent and is connected, and the port of export of interior conduit 4 is provided with plug 5 with holes, and the port of export of the port of export of interior conduit 4 and Outer Tube 3 is at a distance of 0.4 meter.The slurries of this example adopt water glass solution, 28 ℃ time, add the water of 4 times of volumes to Baume degrees in the water glass that is 38; Gelling agent adopts 8% sodium bicarbonate solution.Water glass slurries and sodium acid carbonate gelling agent are added and are pumped into Outer Tube and interior conduit by grouting pump and gelling agent respectively, and two pump discharges are identical, and slurries and gelling agent mix in latter 5 seconds and can be changed into solid.Because setting time is very short, therefore, even if there is being sloping region also can realize quick blocking.Regulate the injection ratio of slurries and gelling agent can regulate gelation rate.
Embodiment 2
Plugging device, slurries and gelling agent are identical with embodiment 1.It is few 10% that grouting pump flow-rate ratio gelling agent adds pump discharge, and slurries and gelling agent mix in latter 4 seconds and can be changed into solid.
The utility model is not limited to the shutoff of the specific region such as mine laneway or goaf, also can be used for the shutoff that other personnel are difficult to arrive region.The utility model also can be used for two slower component plugging materials of setting rate.
