It is sectional drawing which shows the state mounted in the intake port of a furnace manhole, and a pit.

First, the manhole 300 shown in FIGS. 6 and 7 is specially shaped to mount the first and second tube fixtures 100 and 200 of the present invention. That is, the manhole 300 is different from the inlet 3 of the conventional manhole 1, and the inlet 303 of the manhole 300 has a large diameter portion 305 and a small diameter portion (small) ( 307, the large diameter portion 305 is formed toward the outer wall of the manhole 300, and the small diameter portion 307 is formed toward the inner wall of the manhole 300. Here, the small diameter portion 307 has a diameter of a size that can be inserted into the tube 400.

In particular, a middle diameter portion 309 smaller than the diameter of the large diameter portion 305 and larger than the diameter of the small diameter portion 307 is further formed between the large diameter portion 305 and the small diameter portion 307. The diameter of the middle diameter portion 309 is smaller than the diameters of the first and second pipe fasteners 100 and 200 including the water blocking water blocking agents 140a and 240a, and more preferably, the water blocking blocking agent ( It is preferable to form larger than the diameter of the first and second tube fasteners 100 and 200 except for 140a and 240a. As a result, the inner circumferential surface of the inlet 303 is formed in a step shape by the large diameter portion 305, the middle diameter portion 309, and the small diameter portion 307, whereby leakage can be more effectively blocked.

When the first and second tube fixtures 100 and 200 are inserted into the inlet 303 having such a structure, the first and second tube fixtures 100 and 200 are leak-tight water stopper 140 While contacting the inner surface of the neck portion 305 is located in the large diameter portion 305 and the middle diameter portion (309).

On the other hand, a plurality of support bar support means, for example, an insert (that is, an insert formed with a female thread for inserting a bolt) 310 is embedded in the inner surface of the middle diameter portion 309 of the inlet 303. 160 is coupled to the support bar support means 310. Therefore, the number of support bar support means 310 embedded in the inner surface of the middle diameter portion 309 is preferably the same as the number of support holes 150.

In addition, the earth hole 320 formed in the manhole 300 also has the same structure as the inlet 303 described above.

The method of mounting the first or second pipe fasteners 100 and 200 of the present invention to the inlet 303 and the toe 320 of the manhole 300 having such a structure will be described below. The method in which the first tube fixture 100 is mounted in the inlet 303 will be described first, followed by the method in which the second tube fixture 200 is mounted in the inlet 303. And the first tube fixture 100 or the second tube fixture 200 is mounted on the earthenware 320 is a method that the first tube fixture 100 or the second tube fixture 200 is mounted on the inlet 303 Since the description is the same as that, the description is omitted.

Referring back to Figure 6, first, the first tube fixture 100 is attached to the predetermined position of the tube 400 by the assembly method as described above, the tube with the first tube fixture 100 is attached to the inlet ( 303 is inserted as described above. As such, when the pipe 400 to which the first tube fixture 100 is attached is inserted into the inlet 303, the support bar 160 passes through the support hole 150 of the first tube fixture 100 and then supports it. When the nut 500 is firmly fastened to the support bar 160 of the portion protruding from the first pipe fixture 100 and finally coupled to the bar support means 310, the first pipe fixture 100 of the present invention. Is mounted in the inlet 303 of the manhole 300.

As such, when the pipe 400 to which the first pipe fixture 100 is attached is mounted in the inlet 303, all the construction is completed when the mortar 600 is finally filled and cured in the inlet 303, and here, Instead of the mortar (600), it may be filled with an epoxy resin having good water tightness.

Referring to FIG. 8, the second tube fixture 200 is fitted to the tube 400 through the through hole 203, and thus, the tube 400 into which the second tube fixture 200 is inserted is formed of the manhole 300. It is inserted into the inlet 303, and thereafter, it is mounted in the inlet 303 by the same mounting method as the first tube fixture 100.

On the other hand, alternatively, the first and second tube fasteners 100 and 200 of the present invention may be mounted on the inlet 3 and the earthenware 5 of the conventional manhole 1, see FIGS. 9 and 10. This will be explained.

9 is a cross-sectional view showing a state in which the tube fixture of the first embodiment of the present invention is mounted in the inlet of a conventional manhole while the tube fixture is attached to the tube, and FIG. 10 is a tube fixture of the second embodiment of the present invention attached to the tube. It is sectional drawing which shows the state mounted in the inlet of the conventional manhole in the opened state.

9 and 10, in order to be mounted on the inlet 3 of the conventional manhole 1, the first or second tube fixture 100 or 200 of the present invention is separately provided on the inner circumferential surface of the inlet 3. Support bar support means 700 should be provided. The support bar support means 700 is provided to protrude on the inner circumferential surface of the inlet 3 with a portion thereof embedded, and the number of the support bar support means 700 is the first or second pipe fixtures 100 and 200. It is preferable that the number of the support holes 150, 250 of the same. Although not shown, the same plurality of support bar supporting means is provided on the inner circumferential surface of the earthenware.

When the support bar support means 700 is provided on the inner circumferential surface of the inlet 3 of the conventional manhole 1 as described above, the support bar is supported in the support holes 150 and 250 of the first or second pipe fixture 100 or 200. The first or second tube fixture 100 or 200 is attached to the tube 400 either by assembly or by fitting, with 160 and 260 partially inserted protruding on each outer surface. Thereafter, the tube 400 to which the first or second tube fixture 100 or 200 is attached is inserted into the inlet 3, and finally the first or second tube fixture 100 to the support bar support means 700. Alternatively, when the support bars 160 and 260 of the 200 are bound by a binding member, that is, a binding hardware or a binding line, the mounting process of the first or second pipe fixing member 100 or 200 in the inlet 3 is completed. . Although not shown in the figure, the same way as in the case of the first or the second pipe fastener 100 or 200, the pipe 400 is mounted.

On the other hand, in the tube fixture of the present invention, it is obvious that the tube fixture of the present invention can be variously modified according to the intake and the earthenware of the tube or the manhole, and in particular, since the tube fixture is provided as an assembly or an integral type, Tube fixtures can be grafted into the tube or manhole in various ways depending on the needs of the construction site.

As described above, since the pipe fixture of the present invention firmly fixes the pipe in the inlet and the inlet of the manhole, the displacement of the tube and the ground subsidence or the ground inequality, etc., generated when the mortar is filled in the inlet and the inlet of the manhole. The displacement of the pipe caused by the change of environment is largely prevented, and the leak is effectively blocked.

In particular, even when the mortar filled in the intake and the earth hole of the manhole is damaged due to the above-described environmental change, the water leakage is effectively blocked by the water leakage blocking agent provided in the pipe fixture of the present invention.

In addition, since the tube fixture of the present invention is located in the mortar filled in the intake and earthenware of the manhole, the bonding property of the cured mortar is increased, and the tube fixture is a compound compounded with industrial by-products such as waste vinyl resin and fly ash. Because it can be manufactured in the environment, environmental pollution is prevented, and the supply price is also low.
