[0001] The present invention relates to a method and apparatus for injecting a filler material, and a method of injecting filler material into the filler material, and filling method}

The present invention relates to a method and apparatus for injecting a filler and a method of injecting a filler into a pipe, and more particularly, to a method of injecting a filler into a pipe, The existing air in the irregular shape existing in the depressed portion or the loose ground portion is converted into a vacuum by using one device in the pipeline for the depressed portion or the loose ground portion generated at the back surface of the study, It is possible to measure the corresponding depression amount and to fill the filler material corresponding to the measured depression amount in a vacuum state, thereby diagnosing the depression of the depression of the pipeline and increasing the filling rate of the filler material, It is possible to greatly improve the workability and the accuracy according to the diagnosis and the filling. Rehabilitation quality and diagnosis and maintenance diagnosis depression filler Greater amounts of a rear duct invention so as to greatly improve the safety in the reinforcement process of the injection device, and a rear pipe using the same amount of depression of the diagnostic Greater fill material relates to the injection method.

In general, the joints of the sewer pipe including the waterway buried before 1997, which is the subject of maintenance in recent years, are fitted with concrete collar pipes on the outer sides of both sides of the site butt joint, In the area where sewage is filled in the sewer pipe during the flood or the drainage of the sewage in the downstream is difficult and the sewage is backwardly flowed in the flood water because the gap is not a watertight structure, The water pressure is often applied through the clearance between the outer surface and the concrete collar pipe installed at the buttocks, so that the confluence of sewage and floods scatters the outer surface of the sewer pipe joint and looses the loose soil, A thread having a problem causing a concaved result A.

Also, in the case of the water pipe, when the water pressure applied to the tap water is applied under the condition where the water is rusted and aged due to the elapse of time, the tap water to which the water pressure is applied scour the buried ground of the perforation, And ultimately, the upper ground of the water pipe is depressed.

On the other hand, in Korean Patent Registration No. 10-0568608 (Mar. 31, 2006), the air pressure change amount is measured in a sealed watertight test section, and then the leak amount can be easily obtained by using the correlation between the air pressure change amount and the water leakage amount. A watertightness testing apparatus and method for a sewer pipe using air pressure "is proposed.

At this time, the watertightness testing apparatus of the sewage line using air pressure is composed of a pair of frames connected to each other by a predetermined connecting member and having a cylindrical shape; A packer which is installed along the circumferential direction on the outer surface of each frame and expands so as to be brought into close contact with the inner surface of the sewer pipe by inflow of compressed air; An air injector for selectively injecting compressed air into a watertight test section sealed by a packer installed in each frame; A pressure measuring member for measuring a change in air pressure in the watertight test section; And an arithmetic unit for calculating a leak amount by using a correlation between a pre-input air pressure change amount and a water leak amount of the watertight test section.

(A) a pair of frames connected to each other by a connecting member, and a pair of frames provided on an outer surface of each of the frames, the inflated To a watertightness test section of a sewer line; (b) injecting compressed air into the packer to inflate the packer so as to be in close contact with the inner surface of the sewer pipe; (c) injecting compressed air into the sealed watertight test zone by expansion of the packer; (d) measuring an air pressure change amount of the watertight test section for a predetermined time; (e) calculating a leakage amount of the watertightness test section using the air pressure change amount.

However, the watertightness testing apparatus and method of the sewer pipe using the air pressure having the above-described constitution and the steps are configured not to measure the depression amount of the sewer pipe joint portion because the air pressure is used to measure the amount of water leakage, Since the air is still in the depression of the depressed portion, the air pressure of the same kind is additionally operated by adding the air pressure of the same type at the air pressure difference basically (about 1 kg / cm 2, corresponding to the pressure difference of about 10 m) There is a problem that the working efficiency of the air pressure is lowered and not only the workability is lowered but also the diagnosis accuracy of the air pressure change amount is lowered.

In the method of repairing an index repair agent for a sewer pipe and the method of repairing a sewer pipe by the method described in Korean Patent Registration No. 10-1735617 (May 08, 2017), a camera robot is used to remove damaged parts such as underground buried pipes Repair the damaged part of the sewer pipe by a method of expelling the packer after the packer is moved to the damaged part after precise inspection and then exponentially exposing the packer temporarily and injecting the liquid or gel agent to the damaged part through the nozzle of the packer have.

That is, the repairing system described in the above-mentioned sewer pipe maintenance agent and the repair method of the sewer pipe can not accurately move the compression nozzle of the packer to the damaged part of the buried pipe, In order to improve the disadvantage that the work is not robust and precise, it is necessary to move the packer accurately to the damaged part in the buried pipe, and then perform the repair work using the packer, so that the damaged part of the buried pipe can be more firmly and precisely repaired .

However, since most of the repair methods proposed above are in a state where air is also present in the depression of the existing sewer pipe joint part, the air pressure is basically different (about 1 kg / cm 2, The operation efficiency of the air pressure is lowered, so that not only the workability is lowered but also the diagnosis accuracy of the air pressure change amount is lowered.

In other words, conventionally, in the process of measuring the amount of depression corresponding to the volume of air, the pressure of about 1 kg / cm 2 (corresponding to the pressure of the head difference equivalent to 10 m of elevation difference) A pressure higher than the pressure of about 1 kg / cm 2 must be additionally applied to diagnose the amount of depression using the air pressure. This may cause unnecessary elevation of the ground around the pipeline, Or the safety can be lowered in a power pipe or a water pipe.

Thereafter, when the depression amount diagnosis and filling material injection device is pulled out of the pipeline 10 from the inside of the maintenance subject pipeline 10 by using the winch or the winder 25 and the pipeline is withdrawn, the maintenance for the pipeline is completed.

Of course, when a large number of depressions 11 are generated in the pipeline 10, it is possible to diagnose and measure the depth of depression with respect to one of the depressions 11, to inject the filler according to the measured depression amount, 27, and then the above-mentioned step may be repeated by moving the cavity-filling-amount diagnosing and filling material injecting device itself to another cavity-forming site 11 again.

Meanwhile, during the above steps, the vacuum pump 31 is operated to suck the existing air in the depressed portion 11 including the loose ground portion 12 of the pipe backside to convert the depressed portion 11 into a vacuum state, 11) can be diagnosed and measured and can be numerically confirmed and stored in the control panel 50. In this case, even if the air is taken out, the depressed portion 11 is not converted into the vacuum state and the depression amount of the depressed portion 11 The depression 11 of the joint portion of the conduit 10 is communicated with the joint portion of the adjacent conduit 10 or in the state of communicating with the external mound claws or the mouse cave, It is determined that the vacuum is not established in the vacuum pump 11 and the operation of the vacuum pump 31 is stopped.

Subsequently, the dye-containing air pump 39 connected to the dye-containing air hose 38 is operated in the injection direction, so that the channel (the depressed portion including the loosened ground portion 12 on the back surface of 10) The air having the state in which the pigment is mixed into the ink tank 11 is filled.

When the dye-containing air is filled in the depressed portion 11 including the loose ground portion 12 on the back surface of the pipe, the dye-containing air pump 39 is operated in the discharge direction, which is the opposite direction before, It is preferable that the dye-containing air remaining in the present depression 11 (that is, the depression 11 of the joint portion of the duct 10 is in communication with the joint portion of the adjacent duct 10) Mixed air remaining air in the current depression 11 is discharged to the outside through the dye-containing air hose 38, and the dye-containing air is discharged through the dye-containing air discharge gauge 40 to the dye- And the amount of depression of the depression 11 (i.e., the volume in the depression) is diagnosed and measured.

At this time, the state information for operating the dye-containing air pump 39 in the discharge direction to discharge the dye-containing air in the loose ground 12 and the depression 11 on the back of the pipeline through the dye-containing air hose 38 , The color change of the dye-containing air passing through the transparent confirmation unit 41 provided on the dye-containing air hose 38 is captured through the camera 34 attached with the light 33, So that the operator of the control panel 50 can confirm the image accurately through visual observation (if the air without the pigment is picked up, it is judged that the dye-containing air injected into the depressed portion 11 is completely exhausted).

When the amount of depression of the depression 11 is diagnosed and measured through the above process, the filler material injection pump 36 connected to the filler material supply hose 37 is operated to insert the filler material supply hose 37 The filler material 60 of organic and inorganic type such as cement mortar is injected by an amount corresponding to the amount of depression previously measured (that is, the amount of dye-containing air).

The amount of the filling material 60 to be injected into the depression 11 through the filling material supply hose 37 may be checked through the filling material pressure gauge 35 provided in the filling material supply hose 37, Since the filling amount of the filler material 60 can be confirmed through the filling material pressure gauge 35, an accurate amount of filler material can be injected and filled into the depression portion 11 corresponding to the volume of the depression portion 11.

Thereafter, as described above, the air in the cylindrical closed tube 27 of the apparatus for inspecting the depression / filler material is discharged through the air supply hose 29 and shrunk, Withdraw from the inside of the pipeline 10.
