Description

Electric power manhole}

More particularly, the present invention relates to a power hole manhole, and more particularly, to a power hole manhole, which is easy to install and which can be bent and expanded or shrunk in the longitudinal direction, is inserted between the junction faces of a box culvert and an inspection port, And a power hole manhole that can prevent the liquid in the ground, such as ground water, from being introduced into the inside in a situation such as uneven settlement.

Generally, electric cables are installed on the ground but they are mainly buried in the underground in complex areas like the city center. On the ground, there is a problem of interfering with complex buildings and street structures or obstructing aesthetics, and most of them are buried underground.

The electric cables embedded in the ground must be connected to each other at certain intervals.

Meanwhile, the power hole manhole may be directly installed on the site. However, recently, a construction is performed in a factory separately for air shortening or the like, and the construction is performed only in the field. For this purpose, a plurality of concrete box cullet , "Box-culvert") are jointed at the site to install a power hole manhole.

In the case of installing the power sphere by the pre-casting method, it is most important to firmly bond the box-cul-mural joint surfaces. For this purpose, generally, concave joint grooves are formed on the opposing joint surfaces of the adjacent box culverts and grout materials such as non- .

However, when the earthquake or uneven settlement occurs, cracks occur in the grout material existing between the joint surfaces of the box culver, and leakage occurs inside and outside the box culvert.

To solve this problem, a method of installing an index member in the opposing joining recesses of the box culver has been proposed.

However, since most of the index members are constructed so as not to easily cope with the behavior due to the cracks occurring in the box culvert, the index members disposed in the opposing joining grooves of the large box culler are very bulky and complicated in shape, It is difficult to install the index member fixed to one side box culvert in the opposite side connecting grooves of the box culler because of its large and heavy weight, There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems,

It is an object of the present invention to provide a method of manufacturing a box-shaped culvert, which is easy to install between opposed faces of a box culvert and which can be extruded without a mold, And the grooved material is uniformly adhered to the box-hull opposing joint grooves so that the pleat-like closed reinforcement plate capable of expanding and contracting in accordance with the cracks of the box-shaped hull-joined surfaces is sandwiched between the joint surfaces of the box- Thereby providing a power hole for the inserted manhole.

In order to solve the above-described problems, a power hole manhole formed by connecting a plurality of pre-casted box culverts to each other at a construction site to connect the corrugated hollow and the corrugated hollow, A multi-directional wrinkle portion having a wrinkle-like rim capable of directionally expanding and contracting by a lateral pressure or a tensile force and capable of bending at 90 degrees in the lengthwise direction of the witness plate and overlapping at the time of bending; 1 and the second plate-shaped portion are inserted between the abutting surfaces of the adjacent box culver.

According to an embodiment of the present invention, the structure of the power plate is simplified, thereby maximizing the ease of manufacture of the plate and the cost of manufacturing the plate, and the shape of the plate and the shape of the box- It is possible to bend 90 degrees at the corners of the box culver. Therefore, it is not necessary to install a separate installation device or method, and the integral plate is installed between the box-culvert joint faces of the power tool manhole It is possible to provide a power hole manhole that is easy to install and has improved index performance.

FIG. 1B is a perspective view illustrating a corrugated closing plate according to an embodiment of the present invention. FIG. 4 is a schematic perspective view showing a hollow closed shape. FIG.

As shown in FIG. 1A, a power cull manhole 1 using a corrugated closing plate 300 according to an embodiment of the present invention can be manufactured by previously manufacturing box culverts 100a and 100b and an inspection port 200 at a factory They are shipped to the site and then installed in a bonded state. Particularly, in order to ensure tight watertightness of the joint surfaces of the box culvert and check port bodies 100a, 100b, and 200a, the box culvert and check port bodies 100a, 100b, and 200a are opened in the channel direction as shown in FIG. In the case of each box structure, a corrugated closing plate is formed in a ring shape to match the cross-sectional shape of the box culvert and check port bodies 100a, 100b, 200a along four sides of the box culvert and check port bodies 100a, 100b, 200a And the wrinkle-type closure watertightness plate 300 having the corrugated hollows 302a closed is provided.

On the upper surface of the inspection port main body 200a is an inspection port top board 200b which can cover the inspection port main body 200a and the top port 200b of the inspection port 200b is separated from the inspection port main body 200a, And may be integrated with the inspection port main body 200a. When the inspection top plate 200b is separate from the inspection port main body 200a, a steel bar may be inserted to join the inspection top plate 200b and the inspection probe main body 200a. In addition, as shown in FIG. 1A, the inspection hole 200 may have various shapes such as a rectangular columnar shape and a cylindrical shape. On the other hand, the manhole cover 200c can be installed on the inspection top plate 200b so that the manhole cover 200c can be installed in and out of the power hall manhole 1, and the manhole cover 200c can be installed according to a general method.

As shown in FIG. 1B, since both ends of the corrugated closing plate 300 can be fitted and fused, a separate edge engaging member (not shown) can be attached to the corners of the box culvert and check port bodies 100a, 100b and 200a, It is possible to avoid the inconvenience of cutting and installing the waterproof plate and to prevent the liquid in the ground such as ground water from flowing into the power hole of the manhole (1) from the part where the waterproof plate is broken by fitting the both ends of the waterproof plate have. That is, the corrugated hollow 302a is closed and can be completely cut off from the outside.

On the other hand, a cable insertion pipe 161 is installed on the finishing plate 160, and this is installed in a manner that is generally performed, and thus a description thereof will be omitted.

FIG. 2A is a schematic perspective view of a corrugated closing plate according to an embodiment of the present invention, FIG. 2B is a perspective view of a corrugated closing plate according to an embodiment of the present invention, Fig. 5 is a partial enlarged view for showing a shape. Fig.

As shown in FIG. 2A, the corrugated closing plate 300 according to the embodiment of the present invention is formed of a horizontal plate member. The center is formed by the expansion and contraction in a direction perpendicular to the center line, The first plate upper portion 301 is provided on both sides of the multi-directional wrinkle portion 302 and the multi-directional wrinkle portion 302, which are capable of being bent 90 degrees along the longitudinal direction of the diaphragm- And the second plate portion 303 are integrally connected and extrusion-molded with a synthetic resin material.

In the corrugated closing plate 300 according to an embodiment of the present invention, the multi-directional corrugated part 302 surrounds the corrugated hollow 302a and the corrugated hollow 302a, and a predetermined lateral pressure and a tensile force And a corrugated rim 302b capable of directionally expanding and contracting.

Particularly, since the corrugated rim 302b surrounds the corrugated hollow 302a and forms a multi-layer structure, when cracks are generated in the joint surfaces of the box culvert and the check port bodies 100a, 100b and 200a, It is easy to maintain elongation and durability.

The corrugated frame 302b may have an air hole 102c communicating with the outer space so that the corrugated hollow 302a can be easily changed in accordance with elongation and contraction.

The first and second plate portions 301 and 303 are connected to each other in the height direction of the multi-directional wrinkle portion 302, and the thickness of the first and second plate portions 301 and 302, Since the thickness of the rim 302b is equal to the thickness of the rim 302b, durability can be improved.

A rectangular shape having a long side opposite to the direction perpendicular to the first and second plate portions 301 and 302 is formed in a substantially rectangular shape having a vertical width larger than the left and right width of the corrugated rim 302b It is preferable to allow more tension in the transverse direction when cracks are generated at the joint surfaces between the box culvert and the check port bodies 100a, 100b and 200a.

The length of the long side of the corrugated frame 302b is longer than the length of the box culver 100a in which the multi-directional wrinkle 302 is installed or the length in which the elongating and contracting groove 110a of the check port main body 200a can be closed Even if the multi-directional wrinkle 302 is pulled by a tensile force due to cracks between the box culvert and the check port bodies 100a, 100b and 200a, the expelling performance can be continuously maintained .

The long sides of the corrugated rim 302b are symmetrically arranged once in the horizontal direction of the first and second plate portions 301 and 303 and in the vertical direction of the first and second plate portions 301 and 303, The shape bent inward toward the corrugated hollow 302a is suitable for inducing the exponential due to the cracks between the joint surfaces of the box culver 100a or 100b or the check port main body 200a, It is most preferable to consider the durability and the degree of tensile strength of the multi-directional wrinkle portion 302 because it can maintain a sufficiently low pressure state in the multi-directional wrinkle portion 110a.

Even when the long sides of the corrugated rim 302b are bent upward and downward two or more times to form a large number of corrugations, the corrugated rim 302b can support the load at the time of occurrence of cracks between the joint surfaces of the box culvert and check port bodies 100a, 100b and 200a It is possible to provide the durability of the corrugated closed-circuit voltage plate as much as possible. Further, the multi-directional wrinkle portion can maintain the waste pressure structure in the stretchable and contractible groove.

The protrusions 304 perpendicularly formed on the front surface and the back surface of the first plate upper portion 301 and the second plate upper portion 303 are extruded in a lengthwise direction integrally with the corrugated closing plate 300, When the height of the protrusion is high, it can be solidly integrated with the grout material 130 when it is embedded in the grout material 130, and the movement distance of the liquid can be increased even in a situation where liquid in the ground such as ground water penetrates Thereby maximizing the frictional resistance of the flow velocity and minimizing leakage.

The protrusions 304 are preferably formed in two to four rows at regular intervals along the longitudinal direction of the corrugated closing plate 300. [

The first plate upper portion 301 and the second plate upper portion 303 are spaced apart from each other by a predetermined distance along both edges of the farthest end of the multi-directional wrinkle portion 302, And may be formed in a direction perpendicular to the upper surface of the second plate.

The spacers 305 are installed in the fixing grooves 110b of the box culver 100a or the inserting port main body 200a or the first and second plate tops 301 and 303 When the grout material 130 is injected so that the first and second plate tops 301 and 302 are not in close contact with the surfaces of the fixing grooves 110b and the placement grooves 120, Is filled tightly with the fixing grooves 110b or the engraved recessed concaves 120 but also with a large area with respect to the ends of the fixing grooves 110b or the casting recessed concaves 120 So that the coupling force between the first and second plate portions 301 and 303 and the grout material 130 is increased and the multi-directional wrinkle portion 302 can be easily tensioned.

The protrusions 304 may be reduced in height toward both sides of the multi-directional wrinkles 302, and the protrusions 304 may be integrally extruded in the longitudinal direction of the corrugated closing plate 300 .

Since the corrugated closing plate 300 has the corrugated hollow 302a, even if the multi-directional corrugated portion 302 has a predetermined volume, the corner portions of the box culver 100a and 100b and the corners of the main body 200a The corrugated rim 302b is overlapped to allow 90 degree bending. Even if the 90 degree bend is performed, the rupture or rupture does not occur. 2B, the corrugated rim 302b of the multi-directional wrinkle 302 may be pressed and bent at corner portions of the box cages 100a, 100b and the inspection port main body 200a, So that the index performance can be maintained even at the corner portion.

Since there is no great difference in the configuration of the joint surfaces of the box cages 100a and 100b and the joint surfaces of the checker main body 200a, the reference numerals in the drawings are shown to be unified, and the terms will also be described in unison. On the other hand, at the time of joining the box culvert 100b and the inspection unit 200, the fixed installation recess 110 may be provided at any one of the connection port 150 of the box-culvert upper surface or the connection surface of the inspection port main body 200a, The on-site casting fill recesses 120 are provided in the other.

In the state before the box culver 100a or 100b or the inspection port main body 200a are joined to each other, the corrugated closing plate 300 may be fixed to the one box culvert 100a or the connecting port 150. [ That is, the first plate upper portion 301 is fixedly embedded in the grout material 130 filled in the fixing grooves 110b of the fixed mounting concave portion 110. The multi-directional wrinkled portion 302 is pressed and fixed Is provided in the box cowl 100a or the connecting port 150 in a state in which the inlet of the elasticity allowing groove 110a of the recess 110 is closed, that is, Can be. In this case, the second plate top 303 is protruded toward the joint surface of the other box culver 100b or the check port main body 200a.

The first plate upper portion 301 is fixedly embedded in the grout material 130 filled in the fixing grooves 110b. However, since the grout material 130 is not filled in the stretchable and contractible grooves 110a, The wrinkle portion 302 is located in the empty space of the stretchable and contractible groove 110a in a state where the wrinkle portion 302 can be expanded and contracted.

When the two side box culverts 100a and 100b or the inspection port main body 200a approach and their abutment surfaces are in contact with each other, the second plate upper part 303 is moved to the side of the other box culver 100b or the check port main body 200a And is inserted into the casting recess 120. Generally, when the joint surfaces of the two side box culverts 100a, 100b or the inserting port main body 200a are in contact with each other, the joint surfaces are prevented from being directly touched to each other and broken, and sealing spacers (140) may be installed.

The grout material 130 is filled and filled in the concave recessed portion 120 in a state where the joint surfaces of the two side box culver 100a or 100b or the inserting port main body 200a are in contact with each other, The grout material 130 is injected and filled in the gap between the joint surfaces generated by the grooves 130 and 140.

The second plate portion 303 positioned in the concave portion 120 is buried in the grout material 130 and is fixed while being buried when the grout material 130 is cured.

When the both side box culver 100a or 100b or the inspection port main body 200a are in contact with each other, the corrugated closing plate 300 according to the present invention is installed on both side of the box culver 100a or 100b or the check port main body 200a So that the liquid in the ground such as ground water can be effectively prevented from flowing into the power hole manhole 1 through the joint surface.
