Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wastewater discharge apparatus,

[0001] The present invention relates to an environmental wastewater discharge position and a pupil search apparatus, and more particularly, to a pupil search apparatus which is inserted into a pipeline which needs to be repaired by a non-excavation method to check whether cavities are formed in the ground And collecting the contaminated soil to confirm the discharge position of the wastewater.

Generally, pipelines of various water and sewage lines buried in the ground may become obsolete and can not perform their functions over a long period of time. For example, corrosive phenomenon or crack phenomenon may occur in the pipeline, causing contamination of drinking water, soil, ground water, etc., or a problem that the water or sewage can not flow smoothly.

Therefore, it is very important to continuously manage and repair various water supply and sewerage pipes buried in the ground. Korean Patent No. 10-1168048 discloses a method of repairing a pipeline in which damage such as cracks is caused by a non- Water pipe unconfined pipe hardening method '.

As shown in FIG. 1, a method of hardening a water supply and drainage unscored pipe is a method in which a reinforcing tube is inserted into a pipe to cover the inner wall of the pipe with a reinforcing tube and acts on a pipe having a size difficult for an operator to enter can do.

In this way, in repairing the old pipe line in which damage such as cracks is generated, the above-mentioned uncured pipe line hardening method has an advantage that it is possible to reinforce the old pipe line without digging the ground. In addition, Therefore, it can be said that there are many advantages in terms of workability, reliability, economical efficiency, and so on.

However, it is very important to check the existence of the pores in the ground before repairing the pipeline by arranging the above-described reinforcing tube or separate regenerating pipe on the inner surface of the pipeline. That is, if the ground settlement due to the pupil occurs after the pipe repair work is performed by the non-excavation method, there is a problem that the repair work of the pipe line must be carried out by dugging the ground after all.

In general, the pupil 1 is often formed on a cracked portion of the conduit 5 or a connecting portion between the conduit 5 and the water pipe 7 of a house or a building, as shown in Fig.

However, due to the air pressure, gravity, etc. formed in the pupil 1, the surrounding soil is washed down to the cracked portion of the pipeline 5 or to the side of the connection portion between the water pipe 7 and the pipeline 5, The strength or pressure of the gravel disposed at the lower part of the pipe 1 may have a stronger binding force than the gravel in the ground where the pores 1 are not formed. It is difficult to grasp the presence or absence of (1) in reality.

On the other hand, the pipeline used for drinking water needs to be thoroughly protected and managed from external pollution because it is a water supply facility whose main purpose is sanitary hygiene and fire extinguishment. Therefore, it is important to immediately identify the source of pollution when the pipeline is contaminated by external environment or habitual dumping of wastewater, and to perform repair work accordingly.

However, in the case of a pipe having a size difficult to enter by a worker, there is a disadvantage in that it can not accurately grasp the position and condition of contamination of the soil by wastewater. Thus, after excavating the land along the entire length of the pipe by the excavation method, The work cost and the work time are increased while the working efficiency is lowered.

Accordingly, the applicant of the present invention has proposed the present invention to solve the above-mentioned problems, and as a related art document related thereto, Korean Patent No. 10-1168048 entitled " Water and sewage irrigation pipe hardening method "

The endoscope camera 141 is inserted into the perforation hole formed in the inner wall of the channel 5 and the ground by the perforation 130 by the configuration of the transfer unit 143 as described above, To be visible to the naked eye.

Accordingly, the endoscope camera 141 can be rotated by the rotation of the lower housing 121 and moved to a position corresponding to the position of the perforation hole formed by the perforation 130, Is inserted into the perforation hole by means of the guide member 143 to photograph the presence or absence of the formation of the pupil, and the operator can transmit the photographing information.

The collecting unit 150 collects the pulverized material, that is, the soil generated when the perforation drill 134 of the perforator 130 punctures the inner wall of the duct 5 and the ground disposed thereon The worker on the ground can analyze the polluted condition of the pipeline (5) and the ground based on the collected soil water.

4 and 5, the collecting part 150 may be detachably attached to the perforation 130. The collecting part 150 may be detachably attached to the upper part of the lifting housing 132, A horizontal plate 152 provided at an upper end of the first tubular member 151 and having an insertion hole into which the drilling drill 134 can be inserted; A second tubular member 153 provided at an upper portion of the second tubular member 153 and forming a space S in which the soil dropped by the drilling drill 134 can be collected and a space S formed by the second tubular member 153, And a third tubular member 154 provided in the space S for receiving a longitudinal portion of the drilling drill 134 disposed in the space S.

The first tubular member 151 has a cylindrical shape having an open upper part and a lower part as a whole, and may be a part detachably coupled to the upper part of the lifting housing 132.

The first tubular member 151 is detachably coupled to the upper portion of the lifting housing 132, and various known coupling methods can be used.

For example, the first tubular member 151 may be coupled to the lifting housing 132 (i.e., the first tubular member 151 and the second tubular member 132) in such a manner that the inner tubular member 151 and the upper outer surface of the lifting housing 132 are screw- As shown in Fig. The first tubular member 151 may be detachably coupled to the lifting housing 132 in an interference fit manner.

The lower end of the first tubular member 151 may be inserted into the through hole 125 in which the lifting housing 132 is received and detachably coupled to the upper portion of the lifting housing 132. When the lifting and lowering housing 132 is lifted or lowered by the lifting rod 131, the first tubular member 151 is lifted or lowered by the lifting rod 131 to the inside of the upper housing 123 partitioning the through hole 125 It is preferable to have an outer diameter smaller than the inner diameter of the through hole 125 so as to be in contact with the side surface.

The horizontal plate 152 may have one end connected to the entire upper circumferential surface of the first tubular member 151 and the other end extended horizontally in a direction in which the drilling drill 134 is disposed. The horizontal plate 152 is formed with a hole 152a through which the drilling drill 134 can pass.

One end of the second tubular member 153 may be connected to the entire upper circumferential surface of the first tubular member 151 and the other end may extend upwardly in a radial direction.

As described above, the second tubular member 153 forms a space S in which the soil pulverized by the drilling drill 134 can be collected. The space S is formed in the second tubular member 153, The inner surface of the member 153 and the upper surface of the horizontal plate 152. Therefore, the soil can fall and collect in the space S defined by the second tubular member 153 and the horizontal plate 152.

The third tubular member 154 prevents the soil falling into the space S from flowing into the hole 152a formed in the horizontal plate 152 and flowing out to the lower portion of the horizontal plate 152 And can protect the longitudinal portion of the perforated drill 134 from a rockfall.

One end of the third tubular member 154 may be connected to the hole 152a formed in the horizontal plate 152 and the other end may extend in a direction parallel to the longitudinal direction of the drilling drill 134 .

Therefore, one end portion in the longitudinal direction of the second tubular member 154 may block the inflow of the soil collected in the space S into the hole formed in the horizontal plate 152. The second tubular member 154 is inserted into the second tubular member 154 when the stone or the stone contained in the ground falls during the drilling of the inner wall or the ground of the channel 5 by the drilling drill 134. [ May be mitigated. For reference, the collecting unit 150 is preferably made of a metal material capable of maintaining durability from the load of the soil dropped by the drilling drill 134 or the impact caused by the stone.

The third tubular member 154 has an inner diameter dimension that is not interfered with the rotation of the drilling drill 134. That is, the inner diameter of the third tubular member 154 may be greater than the diameter of the drilling drill 134, so that the lengthwise portion of the drilling drill 134 received in the third tubular member 154 The third tubular member 154 can be rotated in a non-contact state with the inner surface of the third tubular member 154.

For reference, a cap (not shown) may be provided at the upper end of the third tubular member 154. The cap serves to prevent the inflow of soil to the open top of the third tubular member 154 and forms a hole through which the drilling drill 134 can pass. In addition, the hole formed in the cap has a size that does not interfere with the rotation of the drilling drill 134.

The collecting unit 150 may further include a tubular flow preventing member 155 provided on the bottom surface of the horizontal plate 152.

The flow preventing member 155 may be detachably coupled to the outer surface of the protrusion 132a protruding from the upper surface of the lifting housing 132. [ The manner in which the flow preventing member 155 is detachably engaged with the protruding portion 132a can be realized by a method in which the flow preventing member 155 is screwed to the inner surface of the flow preventing member 155 and the outer surface of the protruding portion 132a, A method of inserting the flow preventing member 155 into the protruding portion 132 in a forced fit manner may be used.

Therefore, the flow of the collecting part 150 can be further prevented from the vibration or shock generated when the perforation drill 124 punctures the inner wall of the channel 5 and the ground.

If the collecting unit 150 is swung from the vibration or impact generated by the drilling drill 124 and the third tubular member 154 interferes with the rotation of the drilling drill 124, The drilling drill 124 and the collecting part 150 may be damaged by contact with each other.

Since it is very important to prevent the flow of the collecting part 150 from the vibration or shock generated when the drilling drill 124 punctures the inner wall of the channel 5 and the ground, It is preferable to further provide a flow preventing member 155 which can be detachably coupled to the lifting housing 132,

6, the collecting part 150 having the above-described structure is lifted together with the lifting housing 132 lifted to the upper part of the upper housing 123 by the lifting rod 131 , The soil ground by the drilling drill (124) can easily fall to the collecting part (150).

The operator can separate the collecting part 150 from the lifting housing 132 and obtain the soil stored in the collecting part 150 to utilize the soil to determine the contamination state of the ground or the location of the contamination source.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments.
