The first injection member 10 includes a first half pipe 12 and a first support plate 14. The first half pipe 12 extends up and down (along the z-axis). The first half pipe 12 has an arc of semicircular cross section perpendicular to the extension axis (in the xy plane), and has a first engagement step BP on the inner surface of the upper end in the (+ z direction). The role of the first latching jaw BP will be described later. The first support plate 14 is connected to the lower end of the first half pipe 12 (-z direction) so as to be substantially perpendicular to the extending direction of the first half pipe 12.

The second injection member 20 has a configuration similar to that of the first injection member 10. That is, the second injection member 20 also includes the second half pipe 22 and the second support plate 24. The second half-pipe 22 extends vertically (along the z-axis). The second half pipe 22 has an arc of semicircular cross section perpendicular to the extension axis (in the xy plane) and a second engagement step BP on the inner surface of the upper end in the (+ z direction). The role of the second latching jaw BP will be described later. The second support plate 24 is connected to the lower end of the second half pipe 22 (-z direction) so as to be substantially perpendicular to the extending direction of the second half pipe 22.

The first injection member 10 and the second injection member 20 may be coupled to each other and a pipe extending vertically by the first half pipe 12 and the second half pipe 22, Respectively. The clamp 30 serves to maintain the engaged state of the first half pipe 12 and the second half pipe 22. The clamp 30 may have a variety of configurations, for example, as shown in Fig. 1, a semicircular first extension 31 and a semicircular second extension 32 may be spring- And may have a structure connected to the elastic member 33. The first extension 31 and the second extension 32 of the clamp 30 can maintain the first half pipe 12 and the second half pipe 22 in close contact with each other.

The inner fixed cap 40 may be positioned within the combination of the first injection member 10 and the second injection member 20 and particularly the first and second injection jaws BP, The position can be fixed by the second engaging jaw BP of the member 20. [ That is, the inner fixed cap 40 can be seated on the first and second stopping bosses BP and BP. The external fixed cap 50 is positioned such that at least a portion of the internal fixed cap 40 is positioned within the first half pipe 12 and the second half pipe 22 and the (+ z (+ Z direction) upper surface of the second half pipe 22, and the (+ z direction) upper side of the inner fixed cap 40. The upper surface In particular, threads and threaded bosses are formed on the outer surface of the upper end of the first half pipe 12 and the second half pipe 22 in the + z direction, and a thread and a thread are formed on the inner surface of the outer fixed cap 50 , The combination of the first half pipe (12) and the second half pipe (22) and the external fixing cap (50) can be fastened together so as to be detachable in a screw coupling manner.

The inner fixed cap 40 is used to inject air into or out of a pipe extending vertically (in the z-axis direction) when the first injection member 10 and the second injection member 20 are engaged And a filler passage 42 through which the filler can be injected into the pipe. Of course, the inner fixed cap 40 may have only one passage, and one of the passages may be used to inject or discharge air, and also to inject the filling material. However, as described later, it may be necessary to discharge the remaining air to the outside while injecting the filler into the pipe, so it is preferable that the inner fixed cap 40 has the air passage 41 and the filler passage 42, respectively Do.

The backflow prevention valve 43 or the backflow prevention valve 43 is provided at the end of the first support plate 14 and the second support plate 24 (-z direction) of the air passage 41 and the filler passage 42 of the inner fixed cap 40, The lid 45 is mounted. 3, the check valve 43 is located at the end of the air passage 41 of the inner fixed cap 40 and the check valve 45 is installed at the end of the filler passage 42. The functions of the check valve 43 and the check valve 45 will be described later.

On the other hand, the external fixed cap 50 has a hole corresponding to the passage of the internal fixed cap 40. The outer fixed cap 50 also has the air hole 51 and the filler hole 52 as shown in Figure 2 and the like if the inner fixed cap 40 has the air passage 41 and the filler passage 42 respectively .

Of course, the cavity filling device may further include a protrusion weight plate 60 (see FIG. 5) in addition to the first injection member 10 and the second injection member 20 as described above. The uplifting weight plate 60 has a through hole at the center of the through hole so that the vertically extending pipe constructed when the first injection member 10 and the second injection member 20 are coupled can pass therethrough . In addition, the protrusion weight plate 60 has a liquid inlet port 61 and a liquid outlet port 62 so as to be able to receive and discharge the liquid therein. In particular, the weight plate 60 for preventing uplift has a bellows-like structure, which can vary in volume, and as a result, the amount of liquid to be accommodated can be varied depending on the situation.

Hereinafter, a cavity filling method using the cavity filling apparatus as described above with reference to FIGS. 4 to 10 will be described. Fig. 4 shows that a cavity (CVT) is formed in the ground E. In order to fill such a cavity (CVT), it is first necessary to accurately measure the size of the cavity (CVT). When the filler material is injected into the cavity (CVT), if the filler material is insufficiently injected, the cavity (CVT) can not be filled properly. When the filler material is overcharged, And the problem such as rising or rising is caused. If the cavity (CVT) is filled with the filling device according to the present embodiment, the occurrence of such a problem can be effectively prevented.

First, as shown in FIG. 5, the first injection member 10 and the second injection member 20 are fixed to each other by a clamp 30 (not shown in FIG. 5) while being in close contact with each other. The combination of the first injection member 10 and the second injection member 20 is placed at the inlet of the cavity CVT and the pipe formed by the combination of the first injection member 10 and the second injection member 20 (1) into the cavity (CVT). At this time, the end of the restoration membrane 1 extends over the upper end of the pipe formed by the combination of the first injection member 10 and the second injection member 20 as shown in FIG. The restoration membrane 1 may be put into the cavity (CVT) through a pipe in a folded state as if the umbrella is folded as shown in Fig.

The first injection member 10 and the second injection member 20 are coupled to each other so that the restoration film 1 is positioned therebetween and the first injection member 10 and the second injection member 20 are clamped by the clamp 30, 2 injection member 20 may be fixed and at least a part of the recovery film 1 may be put into the cavity CVT while positioning them at the inlet of the cavity CVT.

In this state, the inner fixed cap 40 is positioned in the combined body of the first injection member 10 and the second injection member 20 so that its position is fixed by the engagement step BP in the pipe, (50) to the upper end of the pipe of the combination of the first injection member (10) and the second injection member (20). At this time, the pipe of the combination body of the first injection member 10 and the second injection member 20 is coupled to the through hole of the protrusion weight plate 60 so that the protrusion weight plate 60 is connected to the first injection member 10 And the second support plate 24 of the second injection member 20 are brought into close contact with the ground E. It is, of course, also possible that the uplifting weight plate 60 is in direct contact with the ground E. The combination of the combination of the first injection member 10 and the second injection member 20 and the protrusion weight plate 60 is achieved by connecting the inner fixing cap 40 and the outer fixing cap 50 to the first injection member 10, And the second injection member 20 may be made before or after the coupling.

After part of the recovery film 1 is placed in the cavity CVT as described above, the size of the cavity CVT is measured by expanding the recovery film 1 in the cavity CVT. Specifically, pressure and temperature are measured by compressing air in a volumetric compressor (CMP, see FIG. 6). And calculates the number of moles of air in the compressor (CMP) based on the measured pressure and temperature. In general, the following equation applies to air.

[Equation 1]

P X V = n X R X T

Where P is the pressure, V is the volume, n is the number of moles of air, R is the gas constant, and T is the temperature. The volume of the space in which the compressor (CMP) receives air is predetermined. Therefore, by measuring the internal pressure and temperature after compressing the air, the number of moles of compressed air in the compressor (CMP) can be calculated.

Thereafter, as shown in FIG. 6, all the air in the compressor CMP is injected into the restoration membrane 1 to expand the restoration membrane 1. The restoration film 1 thereby fills the cavity (CVT). It is possible to insert a nozzle connected to the compressor CMP into the air passage 41 of the internal fixed cap 40 when all the air in the compressor CMP is injected into the restoration membrane 1. [ In this case, the above-described check valve 43 has a structure in which, for example, the through-hole is provided therein, the through-hole is closed when the nozzle is not inserted, and the nozzle is inserted through the through-hole when the nozzle is inserted Lt; / RTI >

On the other hand, in order to prevent the ground from rising due to the high air pressure in the restoration membrane 1, the liquid is injected into the protrusion weight plate 60 through the liquid inlet 61 of the protrusion weight plate 60, The restoration membrane 1 can be inflated in such a state that the preventing weight plate 60 presses the ground E or the like. As described above, since the uplift weight plate 60 has a bellows-like structure, a sufficient amount of liquid can be injected into the uplift weight plate 60. [

Thereafter, the pressure and temperature in the restoration membrane 1 are measured using a pressure gauge / thermometer 70 as shown in Fig. Since the nozzle connected to the compressor CMP is inserted into the air passage 41 of the inner fixed cap 40, the pressure gauge / thermometer 70 is inserted into the air passage 41 of the inner fixed cap 40, Can be inserted into the passage (42) to measure the pressure and temperature in the restoration membrane (1).

At this time, the backflow preventing lid 45 at the lower end of the filling material passage 42 has a plate shape and one side is fixed to the inner fixing cap 40 by an elastic member such as a spring, and the pressure gauge / thermometer 70 is inserted One end of the pressure gauge / thermometer 70 pushes the backflow preventing lid 45 to measure the pressure and temperature of the air in the pipe of the combination of the first injection member 10 and the second injection member 20 . In order to prevent the air in the restoration membrane 1 from being discharged to the outside in the course of course, similar to the above-described backflow prevention valve 43, a material having elasticity inside the through- . ≪ / RTI > Accordingly, when the pressure gauge / thermometer 70 is not inserted, the through hole is closed, and when the pressure gauge / thermometer 70 is inserted, a part of the pressure gauge / thermometer 70 can be inserted through the through hole.

The volume of the restoration film 1 filled with the cavity CVT can be calculated using the pressure and temperature in the restoration film 1 thus measured and the number of moles of air in the predetermined compressor CMP. This can also be calculated by Equation (1) as described above. For reference, if the pressure in the recovery film 1 measured in this process is not sufficiently high, it can be judged that the recovery film 1 has not filled all the cavities (CVT). Therefore, if the pressure in the recovery membrane 1 measured in this process is not sufficiently high (for example, at atmospheric pressure or below), the number of moles of air in the compressor CMP can be reduced by using a compressor CMP capable of providing a larger volume of compressed air We need to do it again from the calculation process.

On the other hand, it is preferable that the recovery film 1 has elasticity so that it can sufficiently fill the cavity (CVT) by expansion. If the restoration membrane 1 does not have elasticity, the size of the cavity CVT may be larger than the size of the restoration membrane 1. Therefore, when calculating the volume of the restoration membrane 1 in the cavity (CVT) using the pressure and temperature measured using the pressure gauge / thermometer 70 as shown in Fig. 7, If it is approximately equal to the predetermined volume, then in this case it can be judged that the restoration membrane 1 has not filled all of the cavity (CVT). It is therefore necessary to replace the recovery membrane 1 with a larger volume and perform again from the beginning.

After the size (volume) of the cavity (CVT) is measured through the above process, the filler FM is injected into the restoration film 1 in the cavity (CVT) as shown in FIG. 8, the air in the restoration film 1 is discharged, and then the filling pipe FP of the filling device FM is inserted into the filler passage 42 of the inner fixing cap 40 The filler FM can be injected into the restoration membrane 1 after the end thereof is positioned in the restoration membrane 1. [ When the filler FM is injected into the restoration film 1 as described above, if air remains in the restoration film 1, it may not be possible to fill the interior of the restoration film 1 only with the filler FM. Therefore, while the air remaining in the restoration membrane 1 is discharged to the outside through the air passage 41 of the inner fixed cap 40, the filler FM is supplied to the restoration membrane 1 ). ≪ / RTI >

Such fillers (FM) may include cement milk, cement mortar, and the like. Of course, it can also be used as a filler (FM) if it can withstand loads and has fluidity before curing. For example, epoxy or plaster may be used. In addition, the filler (FM) may include an iron barite, an asphalt, a chemical or chemical grout, and the like. And if the filler FM is to be quickly cured after being injected into the restoration film 1, the filler material FM may include a quick-setting agent.

On the other hand, in the process of injecting the filler (FM), the pressure in the restoration membrane (1) increases, so that the ground E may be cracked or protruded. 9, the liquid is further injected into the protruding weight plate 60 through the liquid inlet 61 of the protruding weight plate 60 so that the protruding weight plate 60 The ground E can be pressed with sufficient pressure.

Of course, when the filler FM is injected into the reservoir 1, the pressure in the reservoir 1 rises and the ground E may crack or bulge. However, in the case of the cavity filling apparatus according to the present embodiment or the cavity filling method using the same, It is possible to prevent occurrence beforehand. That is, since the volume of the cavity (CVT) was measured before the filler (FM) injection as described above, the amount of filler (FM) required to fill the cavity (CVT) can be predetermined and thus the correct amount of filler FM to fill the cavity (CVT), thereby preventing overfilling or underfilling of the filler (FM).

After the filling of the filling material (FM) is completed or after the filled filling material (FM) has sufficiently cured, the liquid contained inside is discharged through the liquid discharge port (62) of the uplifting weight plate (60) The inner fixing cap 40, the first injection member 10 and the second injection member 20 after the first injection member 10 and the second injection member 20 are separated from the first injection member 10 and the second injection member 20, (20) and the like can be separated. Then, the remaining portion of the recovery film 1 exposed on the upper surface of the paper is removed, and the filling of the cavity (CVT) can be completed as shown in FIG.

According to the cavity filling apparatus and the cavity filling method using the same, the amount of the filling material FM for precisely measuring the size of the cavity (CVT) and accurately filling the cavity can be determined accurately, It is possible to effectively prevent overfilling or overfilling. In addition, since the filler FM is located in the restoration film 1, it is possible to effectively prevent the occurrence of secondary cavities due to the outflow of the filler FM or the contamination of groundwater or the like by the filler FM.

The restoring membrane 1 serving as such may be formed of a material including nylon, polyethylene terephthalate, natural rubber, polyurethane, elastomer, nylon or neoprene.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art . Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
