That is, the body 10 may be inserted into the heat insulating reinforcement pipe 30 in a manner that the body 10 is inserted into the heat insulating reinforcement pipe 30. At this time, the portion of the corrugation 11a formed on the outer circumferential surface of the body 10 is coupled to the inner circumferential surface of the heat insulating reinforcing tube 30 to be in close contact with each other.

2, a heat insulating air layer P is formed between the heat insulating reinforcing pipe 30 and the corrugation 11 of the body 10 to receive air. Since the heat insulating air layer P is formed, heat inside the body 10 heated by the geothermal heat is prevented from rapidly escaping to the outside. That is, the thermal effect is improved.

A support pin 12 protruding inward from the inner circumferential surface of the body 10 and a locking protrusion 13 are formed on the inner circumferential surface of the body 10, 12 can be fixed by inserting the edge portion of the supporting net plate 40 between the engaging tabs 12 and the engaging jaws 13.

For supporting the support plate 40, the support plate 40 may be made of plastic or synthetic resin material having elasticity so that bending can be performed. Therefore, since the supporting net plate 40 can be bent, the supporting net plate 40 can be seated on the supporting jaw 13 beyond the engaging jaw 13.

The edge of the supporting net plate 40 is slid so that the end of the retaining jaw 13 is rounded so that the edge of the supporting net plate 40 is slid over the retaining jaw 13 to be seated on the supporting jaw 12, 13 and does not fall upward. Therefore, it is easy to install the supporting net plate 40 at the time of construction.

Further, the supporting jaw 12 may protrude more than the engaging jaw 13 to firmly support the supporting net plate 40. As shown in the drawing, the support jaw 12 is formed to be longer than the engagement jaws 13 and the engagement jaws are formed on the upper side of the support jaws so as to be spaced apart from each other.

In addition, a plurality of the support jaws 12 may be formed at regular intervals to support the support plate at a plurality of points (two points or three points).

Next, the protective cap will be described with reference to FIG. 3 shows a cross-sectional view of the protective cap of the present invention shown in Fig.

The supporting net plate 40 is mounted horizontally inside the body 10. Accordingly, the geothermal heat is smoothly transmitted from the lower part to the upper part through the space of the mesh 40a.

A pair of pipe holes 41 are formed in the supporting net plate 40. That is, a pair of pipe holes 41 may be spaced apart from each other on the diameter line of the supporting net plate 40 to correspond to each other.

Since the water pipe passes through the pipe hole 41, the inner diameter of the pipe hole 41 is formed to be approximately equal to or slightly larger than the outer diameter of the water pipe, thereby supporting the water pipe so as not to swing to the left and right.

A sleeve 42 is formed on the inner diameter of the pipe hole 41 so as to protrude upward or downward. The sleeve 42 is formed to surround the outer periphery of the inserted pipe, thereby preventing the pipe from swaying in the lateral direction.

The sleeve 42 may have a tubular shape and an inner diameter equal to the inner diameter of the pipe hole 41.

In the prior art, the support pipe is supported by vertically supporting two support plates. In the present invention, however, the support pipe 40 can securely support the pipe by the sleeve 42.

Any one of the pipe holes 41 of the pair of pipe holes 41 may have a shape that is long in a radial direction of the support plate 40 as shown in FIG. It is difficult to insert another water pipe into another circular pipe hole by inserting and fixing any one water pipe into the circular pipe hole 41a. This is because the distance between the circular pipe holes is fixed.

Therefore, considering the clearance between the pipes, one of the pipe holes 41 may be provided as a long pipe hole 41b to easily install the pipe.

Of course, the sleeve 42 may be formed long in the long hole 41b.

Further, the supporting net plate 40 may be formed with a partially cut slit along the radius. The slit 43 may be formed to have a predetermined length from the edge of the supporting net plate 40 toward the center,

It is possible to insert the pipe into the pipe hole 41 by inserting the pipe into the pipe hole 41. However, since the slit 43 is provided, the pipe can be inserted into the pipe from the side of the support plate 40 . At this time, the supporting net plate 40 may be bent in a slanting manner with respect to the slit 43, so that the pipe can be inserted in a state in which it is open.

On the other hand, a preliminary pipe hole 41 may be formed at one side of the circular pipe hole 41 so as to insert a pipe having a different diameter.

It is preferable to use a supporting net plate having a structure in which the preliminary pipe hole 41 having a different diameter is further provided so as to have versatility than that of using a supporting net plate 40 of another standard when the diameter of the pipe is different at the time of construction Do.

At this time, the preliminary pipe hole 41 may be formed on the slit 43, and one or more pre-pipe holes 41 may be provided. In addition, the sleeve 42 may be formed in the preliminary pipe hole 41 as well.

It is preferable that a separate auxiliary hole 45 may be formed at the end of each slit 43. The auxiliary hole 45 can smoothly support the support plate 40 with respect to the slit 43, And to prevent breakage such as tearing of the supporting net plate 40 due to the slit 43 when bending.

For reference, the support plate 40 may be provided with a finger hole 46 for holding the support plate 40 by holding a finger. One or more guide pieces 47 may be formed at the edge of the support plate 40 so as to be in close contact with the inner circumferential surface of the body 10.

The upper lid 50 is positioned on the upper lid projection 25 of the protective cap 20 and the lower lid 60 is positioned on the lower lid 50 The outer diameter of the lower lid 60 is formed to be larger than the inner diameter of the upper support protrusions 25 and the lower support protrusions 26 so as to be brought into close contact with the inner diameter surface of the expanded portion 22.

At this time, the upper surface of the upper lid 50 may have a gripping groove 51 capable of gripping both sides by hand, and the gripping grooves 51 may have a structure of being recessed downward in a direction facing each other .

Also, the upper surface of the lower lid 60 may be formed with a handle 61 protruding upward to facilitate gripping.

Accordingly, the upper lid 50 blocks the inflow of outside air, and the lower lid 60 blocks the geothermal heat inside the body from being discharged through the upper side. A space between the upper lid 50 and the lower lid 60 may be formed to be an empty space, or alternatively, the heat insulating effect may be enhanced through a heat insulating material (not shown).

Next, the support frame will be described with reference to FIG. Figure 6 shows a sectional view of a support frame of the invention.

In the present invention, the body 10 is buried in the ground. However, when the load is continuously applied to the upper portion of the protection cap 20, the body 10 may be depressed by pressure.

Therefore, a ring-shaped support frame 70 may be provided at the lower end of the body 10 to prevent the sinking of the body 10 while enlarging the outer radius of the body 10.

On both sides of the support frame 70, pipe insertion grooves 72 through which pipes can pass are formed.

On the lower surface of the support frame 70, grooves 73 having a shape recessed upward along the circumferential direction may be formed. The groove 73 functions to prevent the support frame 70 from moving left and right by filling the soil when the support frame 70 is buried in the ground.

That is, the support frame 70 prevents the body 10 from sinking due to the expanded portion of the support frame 70, and prevents the body from moving laterally due to the recesses 73.
