BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a construction of a protection line for underground distribution lines according to the present invention. FIG.
2 is an exploded perspective view of the underground distribution line protection pipe according to the present invention.
3 is a side view of the underground distribution line protection pipe according to the present invention.

1 to 3, the underground distribution line protection pipe according to the present invention includes a plurality of unit protection pipes 10, in which a distribution line 1 is wired, and a joint block 20 are connected in series, In particular, by keeping the gap between the unit protective pipe 10 and the joint blocks 20, it is possible to prevent the deformation and deformation of the protective pipe due to the load transferred from the ground and the behavior of the stratum structure (earthquake etc.) A stratum corneum water induction pipe 30 and a drainage belt 40 are applied so as not to penetrate into the protective pipe 10 and the joint block 20.

The unit protection tube 10 is provided inside the protective tube body 11 and the protective tube body 11 with a wiring space along the longitudinal direction in one or more of the lateral direction and the longitudinal direction and supports the power distribution line 1 (Or compartments) of the shelf 12.

The unit protective pipe 10 is not limited to the circular shape shown in the drawing, but may be rectangular, and may be made of a concrete material, a fiber reinforced plastic, or the like.

The joint block 20 connects neighboring unit protective pipes 10 between the unit protective pipes 10 and a space in which both sides of the unit protective tubes 10 are opened in the longitudinal direction And a wing portion 22 protruding from the left and right sides of the joint block 21, respectively.

The inside of the joint body 21 is formed in the same shape as that of the unit protective tube 10 so that the unit protective tube 10 is inserted therein. The outer shape of the unit body 21 can be various shapes such as a square as well as a circle shown in the figure.

It is preferable that an exponent ring is applied between the unit protection tube 10 and the joint block 20 so that the water layer can not permeate through the unit block 10 and the joint block 20.

The wing portion 22 is formed for the installation of the ground water induction pipe 30 and the wing portion 22 is formed so as to extend from the joint main body 21 so as to drain the groundwater layer induced by the drainage belt 40 from the joint block 20 And a pipe connecting portion 24 is formed in which the both sides in the longitudinal direction are respectively opened.

The pipe connecting portion 24 forms a drainage path together with the stratum corneum water induction pipe 30 so that the stratum corneum water induction pipe 30 is connected to the neighboring strata water induction pipe 30 at both sides thereof, The number of stratum cores induced through the water layer 40 is drained via the stratum corneum induction pipe 30 and the pipe connecting portion 24 of the joint block 20.

A structure is provided for draining the ground water introduced through the stratum corneum water induction pipe 30 to other places. For example, as shown in FIG. 3, one side is connected to the pipe connection portion 24 of the joint block 20 And a duct 50 provided at the other side away from the protective pipe.

Positioning means can be applied between the protective pipe body 11 of the unit protective tube 10 and the joint body 21 of the joint block 20 to facilitate their assembly and prevent twisting. The position aligning means is composed of an alignment groove formed along the longitudinal direction so as to be opened to the outside on the outer circumferential surface of the protective pipe main body 11 and an alignment protrusion fitted into the alignment groove on the inner peripheral surface of the body 21.

The joint block 20 is made of the same material as the unit protective pipe 10.

One or more inlet holes may be formed in the wing portion 22 to vertically penetrate the tube connecting portion 24 and communicate with the outside so as to guide the ground water into the tube connecting portion 24. Preferably, the inlet hole is provided with an earthenware net at the entrance thereof so as to prevent the inflow of the gravel.

The stratum corneum induction pipe 30 is composed of a guide pipe body 31 having a tubular shape with openings on both sides in the longitudinal direction thereof and having a drain hole therein, A fastening nut 33 which is threaded on both sides of the belt connecting hole 32 in which the end of the belt 40 is inserted and connected to the longitudinal direction of the guide tube body 31 and is supported by the wing portion 22 of the joint block 20, ).

The guide tube main body 31 is provided with a drainage path which is guided through the drainage belt 40 and induces and drains the stratum water flowing into the drain hole in the inside thereof. So as to prevent the joint block 20 from coming off, and therefore a steel pipe is preferable.

In order to fasten the tightening nut 33, the guide tube main body 31 should be formed with threads on its outer circumferential surface, but not formed entirely on the outer circumferential surface, but formed only at a portion thereof from both ends in the longitudinal direction.

The belt connection hole 32 is formed in accordance with the number of the drainage belts 40 along the longitudinal direction of the guide pipe main body 31 and the drainage belt 40 is formed on the inner circumferential surface so that the drainage belt 40 is not separated, A packing made of a rubber material can be applied.

The tightening nut 33 is threaded on the outer peripheral surface (threaded portion) of the guide tube main body 31 and screwed to be supported by the wing portion 22 of the joint block 20, ) So that the gap is maintained without shaking.

The two ground water induction pipes 30 are connected in the wing portion 22 of one joint block 20 at the pipe connecting portion 34. Since the pipe connecting portion 34 forms a pipe, The tube 30 is connected directly to the tube connecting portion 34 at a free position without being joined.

Since the stratum corneum induction pipe 30 is spaced from the unit protective pipe 10 by a certain distance, the number of stratum cores can be prevented from infiltrating into the joint unit by the unit protection tube 10 and the joint block 20, (1).

The drainage belt 40 is a flexible plate material (impermeable material) provided with an approximately circular drainage groove 41 that is opened upward on the upper surface (or upper and lower surfaces) facing the ground, The unit protection tube 10 is covered at the upper portion to naturally induce the pipe 30 and the left and right sides connected to the stratum corneum water pipe 30 are positioned relatively lower than the center, And guided into the induction pipe (30). That is, the drainage belt 40 forcibly introduces the stratum corneum water into the stratum corneum water induction pipe 30, thereby preventing the number of stratum cores from penetrating the joint portions of the unit protective pipes 10. [

An inlet communicating with the upper portion is formed in the upper part of the drainage groove 41. The inlet is formed to have a width smaller than the diameter of the drainage groove 41 to prevent the reverse flow of the groundwater flowing into the drainage hole 41.

The drainage belt 40 should be kept covered with the unit protective pipe 10 by the belt support rod 42. [

The belt support rods 42 are arranged in a direction across the drainage belt 40 (longitudinal direction of the unit protective pipe 10) and both sides in the longitudinal direction are fixed to neighboring joint blocks 20 via anchors or the like, So that the drainage belt 40 is not separated from the upper portion of the drainage pipe 40.

The belt support bar 42 may have a hollow hollow tubular shape and at least one hole communicating between the inside and the outside. In this case, an absorbent such as a sponge may be inserted. In this case, It is also possible to protect the ground.

The underground wiring line protection pipe according to the present invention can prevent a short circuit or the like of the power distribution line 1 due to the number of strata in the wiring path of the power distribution line 1 by inducing and draining the ground layer water through the stratum corneum water induction pipe 30 It is also possible to prevent deformation and breakage of the protection pipe due to the ground motion and disconnection of the distribution line (1) due to the ground water softening by the stratum water number, and it is also possible to constitute as follows in order to maximize the drainage capacity.

The joint block 20 has a storage unit 25 for storing the number of strata therein and a connection pipe 26 for connecting the storage unit 25 and the pipe connection unit 24 of the wing unit 22 .

The storage unit 25 is a space formed at the bottom of the joint block 20 and may be formed in a rectangular box shape, for example, at the bottom of the joint block 20.

The connecting pipe 26 can be any pipe connecting the pipe connecting portion 24 of the wing portion 22 and the storing portion 25.

That is, since the number of stratum cores inside the pipe connecting portion 24 flows into the storage portion 25 through the connecting pipe 26, it is possible to smoothly induce drainage without causing stagnation of the groundwater inducing pipe 30 Do.

In this case, the groundwater layer stored in the storage unit 25 must be drained. For example, a drain hole communicating with the outside may be formed in the storage unit 25 to drain the groundwater layer into the ground, Method is possible.

The former is disadvantageous in that the underground water can flow back into the storage part 25, and the latter is advantageous in that it induces rapid drainage.

A drain pipe 27 for draining the number of stratum cores stored in the storage portion 25 of the joint block 20 so as to communicate with the storage portion 25 of the joint block 20 between the joint blocks 20, Can be configured.

The pipe 27 is provided with a plurality of pipes such as a steel pipe, a synthetic resin pipe and a corrugated pipe. The pipe 27 is installed between the joint blocks 20 and is connected to the inside of the storage part 25 of the joint block 20, . In other words, the plurality of joint blocks 20 and the plurality of drain pipes 27 form one drainage path, and a channel can be formed at a predetermined interval as described above, and the number of groundwater layers can be guided to the ground at a remote place.
