[Manhole 100 using the RC or PC block of the present invention]

Figures 2a, 2b, 2c and 2d are a construction cross-sectional view, a perspective view, an assembly configuration of the manhole 100 using the RC or PC block of the present invention, a perspective view of the configuration of the RC or PC support block 160 will be.

The manhole 100 using the RC or PC block is embedded in the ground by assembling the segments (100a, 100b, 100c) manufactured in the factory by a precast method up and down, as shown in Figs. 2a and 2b. When the manhole 100 is exposed to the inside, rainwater lamps are collected therein, and when the water level reaches a certain level, it is drained through a drain pipe, for example.

To this end, the manhole 100 is manufactured in the form of a vertical shaft such as a circular or square cross section, but it may be difficult to manufacture, transport, and construct depending on the size. To be able to.

Thus, according to Figures 2a and 2b, including the bottom segment (100a), the middle segment (100b), the top segment (100c), can be manufactured in various cross-sectional shapes such as a square cross section, and made of a concrete member having a constant thickness Just do it.

Thus, if only the number of installations of the intermediate segment 100b is adjusted, the height of the manhole 100 can be arbitrarily adjusted.

At this time, the lowermost segment (100a), the middle segment (100b), and the uppermost segment (100c) may excavate the ground, and assemble around the excavation hole to lift the lifting device and install it downward. It does not matter if the segment 100b and the uppermost segment 100c are assembled from the inside of the excavation space. In addition, it is also possible to install the uppermost segment 100c using the cut of the existing manhole structure.

Accordingly, the manhole 100 of the present invention is constructed by assembling the lowermost segment 100a, the middle segment 100b, and the uppermost segment 100c, as shown in FIGS. 2a, 2b, 2c, and 2d, but the block-out part ( 110), connection flange (120), segment connection bolt (130), manhole cover (140), manhole cover housing (150), RC or PC support block (160), height adjustment plate (170), anchor bolt (180) Will be included.

First, the lowermost segment (100a), the middle segment (100b), the uppermost segment (100c) is a segment connection bolt vertically penetrating the connection flange 120 between the block-out portions 110 formed above and below the horizontal connection surface. It is integrated using (130).

Accordingly, it can be seen that the manhole 100 is installed in a manner in which the manhole 100 is inserted into the excavation hole formed in the ground.

First, the block-out part 110 is the lowermost segment 100a, the middle segment 100b, and the uppermost segment so that the upper and lower ends of the segment connection bolt 130 are exposed, as shown in FIGS. 2A, 2B, 2C, and 2D. Block-out portions are formed on the top and bottom of the horizontal connection surface of (100c), and a plurality of spaces may be formed along the outer circumferential surfaces of the lowermost segment (100a), the middle segment (100b), and the uppermost segment (100c).

Next, the connection flange 120 is a concrete portion between the block-out portion 110 arranged vertically, as shown in FIGS. 2A, 2B, 2C, and 2D so that the segment connection bolt 130 can be penetrated. Through-holes in the form of vertical holes are formed. Accordingly, it can be seen that a horizontal connection surface is formed while the connection flange 120 contacts vertically.

Next, the segment connection bolt 130 is formed based on the horizontal connection surface of the lowermost segment 100a, the middle segment 100b, and the uppermost segment 100c, as shown in FIGS. 2A, 2B, 2C, and 2D. The fixing nut is inserted into the through hole of the connection flange 120 and fastened to the screw portions of the upper and lower ends, and the fixing nut is accommodated in the block-out part 110.

At this time, the water-milling ring 111 is formed by the weight of the segment by using a square ring-shaped groove into which the water-milling ring 111 is inserted in the horizontal connection surface of the lowermost segment 100a, the middle segment 100b, and the uppermost segment 100c. As it is crimped, the ordering performance of the horizontal connection surface can be secured.

Next, the manhole cover 140 opens and closes the opening (S) formed on the upper surface of the manhole 100, as shown in FIGS. 2A, 2B, 2C, and 2D, but is exposed to the pavement surface such as a road above the manhole. It is a lid that is installed as much as possible.

Since the opening (S) is usually formed in a circular shape, the manhole cover 140 is also formed as a horizontal plate having a circular cross section, and a steel material is usually used.

That is, an opening (S) such as a circular cross-section is formed on the upper surface of the uppermost segment (100c) of the manhole (100), which confirms the inside of the manhole (100) through the opening, or discharges rainwater, sludge, etc. to the outside. It is intended to be used as a passage for.

Next, the manhole cover housing 150 has a function for seating the manhole cover 140 around the opening (S), as shown in FIGS. 2A, 2B, 2C, and 2D, on the exposed upper surface. It is formed to have resistance to the applied impact.

That is, the manhole cover housing 150 is installed on the upper surface of the uppermost segment 100c around the opening, and the manhole cover 140 is installed inside the manhole cover housing 150. In general, since the traffic load of the passing vehicle acts on the manhole cover 140, the manhole cover housing 150 is made of steel in most cases.

Accordingly, since the manhole cover housing 150 is made of expensive steel and has a standard, it is undesirable to adjust the height of the manhole cover 140 by adjusting the height of the manhole cover housing 150.

Accordingly, in the present invention, the manhole cover housing 150 can be synthesized by using an RC member, a PC member, a steel plate, and a PC member instead of steel.

As such, the manhole cover housing 150 has a bolt fixing part 151 stepped on the outer edge of the manhole cover housing 150 so that the head of the anchor bolt 180 is accommodated, and the bolt fixing part 151 Between the inner side of the lid seating portion 152 in which the manhole cover 140 can be seated is also formed stepped.

Accordingly, the thickness of the bolt mounting portion 151 and the lid mounting portion 152 formed to be stepped is uniformly standardized and manufactured, and thus a manhole cover seated on the lid mounting portion 152 inside the manhole cover housing 150 ( It may be necessary to adjust the installation height of 140).

That is, the depth of the excavation hole for constructing the manhole 100 in the underground (G) differs due to construction errors, the rise of the pavement due to pavement maintenance, etc., so the manhole cover 140 is exposed to the top surface of the pavement without a step. There are cases in which it must be constructed as much as possible.

It is the RC or PC support block 160 and the height adjustment plate 170 of the present invention to adjust the height of the installation.

Further, referring to FIG. 2A, it can be seen that the upper surface stiffener 153 may be additionally installed on the upper surface, which is the exposed surface, in order to prevent damage to the PC block due to the impact of vehicle impact and other maintenance equipment in the manhole cover housing 150.

That is, while allowing the anchor bolt 180 to be installed through, a steel plate to be covered on the bent upper surface of the manhole cover housing 150 is formed, but an upper surface stiffener 153, which is a steel plate, is further installed.

This upper surface stiffener 153 is formed by integrating the anti-fall pin 154 so that it can be fixedly formed on the bent upper surface of the manhole cover housing 150.

In addition, a rubber packing material 155 is further installed at a portion where the upper surface stiffener 153 and the manhole cover 140 come into contact with each other to prevent breakage and the like.

Accordingly, the RC or PC support block 160 is located on the bottom of the manhole cover housing 150 to expose the opening, as shown in FIGS. 2A, 2B, 2C, and 2D, according to the bottom of the manhole cover housing 150 It can be seen that the present invention introduces a circular ring shape and a horizontal plate shape having a certain thickness, but it can be installed according to the shape of the existing manhole structure.

At this time, the RC or PC support block 160 has a function of being supported by resisting the load transmitted from the manhole cover 140 and the manhole cover housing 150, so that the inside has strong rigidity, for example, a reinforcing grid in the form of a circular ring. It can be seen that (161, wire mesh reinforcement) is arranged horizontally to be buried.

This circular ring-shaped reinforcement grid 161 is disposed on the upper and lower portions of the RC or PC support block 160 to be advantageous in flexural rigidity, so that it is effective against the load transmitted from the manhole cover 140 and the manhole cover housing 150. You can resist while minimizing your own weight.

In addition, since the RC or PC support block 160 has a certain thickness, if one or more are stacked up and down, the height of the manhole cover housing 150 can be adjusted, and the anchor bolt 180 can be penetrated. An anchor hole is formed.

Next, the height adjustment plate 170 is for preventing sliding while absorbing a load while finely adjusting the height of the manhole cover housing 150 as shown in FIGS. 2A, 2B, 2C, and 2D.

Since the RC or PC support block 160 is made of concrete, if a plurality of them are stacked up and down, sliding may occur on the connecting surface that contacts up and down, and damage may occur.

Accordingly, the present invention further installs a height adjustment plate 170 made of elastic rubber material having a relatively thin thickness between the upper and lower surfaces of the RC or PC support block 160 so that the height adjustment plate 170 is expanded and contracted. While allowing the height of the manhole cover housing 150 to be finely adjusted, the RC or PC support block 160 can support the manhole cover housing 150 more stably.

At this time, it is not a rubber material having elasticity, but by using the reinforcing grid as it is as the height adjustment plate 170, it is also further installed between the upper and lower surfaces of the RC or PC support block 160, so that the height adjustment plate 170 is expanded and contracted, While allowing the height of the lid housing 150 to be finely adjusted, it may be effective to prevent sliding.

Accordingly, the height adjustment plate 170 formed of the rubber material and the reinforcing grid is formed with an anchor hole so that the anchor bolts 180 can pass therethrough.

The anchor bolt 180 passes through the manhole cover housing 150, the height adjustment plate 170, the RC or PC support block 160, as shown in FIGS. 2A, 2B, 2C, and 2D, and the head 181 Is fixed to the bolt fixing portion 151 of the manhole cover housing 150, and the bolt portion 182 penetrates the manhole cover housing 150, the height adjustment plate 170, the RC or PC support block 160, and the lower end is It is inserted and fixed to a certain depth on the upper surface of the uppermost segment (100c) around the opening.

Accordingly, the anchor bolt 180 may be connected to each other by using a coupler 183 to adjust the extension length of the bolt portion.

In addition, by further installing a finishing cap 184 which is installed so that the bottom surface is in contact with the upper surface of the bolt fixing part 151 by wrapping the head 181, it is possible to solve problems such as corrosion due to the exposure of the head 181.

When the anchor bolt 180 is used in this way, the manhole cover housing 150, the height adjustment plate 170, the RC or PC support block 160 are integrated and fixed to the top of the manhole. Because it is made in, it is possible to more effectively resist the load transmitted from the manhole cover housing 150.

[Construction method of the manhole 100 using the PC block of the present invention]

Fig. 3a. Figures 3b and 3c is a flow chart of the construction method of the manhole 100 using the PC block of the present invention.

In the construction method of the manhole 100 using the PC block, after forming the excavation hole H in the ground G, the lowermost segment 100a, the middle segment 100b, and the uppermost segment 100c are formed into a block-out part ( 110), the connection flange 120, the assembly construction using the segment connection bolt 130, and the height adjustment plate 170 around the opening (S) of the uppermost segment (100c), RC or PC support block (160), manhole After installing the lid housing 150, the top segment of the manhole cover housing 150 including the height adjustment plate 170, the RC or PC support block 160, and the top stiffener 153 using the anchor bolts 180 By fixing to the upper surface of (100c), the final manhole cover 140 is made through the process of seating the manhole cover housing 150 inside.

First, as shown in FIGS. 3A and 3B, before construction of the manhole 100, in the form of a vertical hole using an excavation device in the ground G, an excavation hole having a certain depth is formed, and the manhole 100 is assembled and installed. After that, the manhole 100 is downwardly inserted into the excavation hole H.

Accordingly, the manhole 100 to be lowered to the excavation hole H is assembled.

Accordingly, at least one intermediate segment (100b) on the upper surface of the lowermost segment (100a), and the uppermost segment (100c) on the upper surface of the intermediate segment (100b) are connected so that the through hole of the flange (120) communicates, and then the segments are connected to the through hole. After the bolt 130 is inserted, the manhole 100 is assembled by fixing the upper and lower ends of the segment connection bolt 130 with a fixing nut in the block-out part 110.

Accordingly, as shown in FIG. 3B, the manhole 100 is assembled and installed, and the manhole 100 assembled and installed by excavating the ground G is lowered.

Accordingly, the manhole 100 includes a lowermost segment 100a, an intermediate segment 100b, and an uppermost segment 100c, and the manhole 100 of a desired depth can be constructed by adjusting the number of installations of the intermediate segment 100b. To be able to.

Accordingly, in this invention, a groove into which the water milling ring 111 is inserted is formed in the horizontal connection surface in which the lowermost segment 100a, the middle segment 100b, and the uppermost segment 100c are in contact with each other up and down. While being compressed by the weight of this segment, it is possible to secure the order performance of the horizontal connection surface,

The segment connection bolt 130 is arranged vertically with the block-out part 110 formed as a block-out part above and below the horizontal connection surface of the lowermost segment 100a, the middle segment 100b, and the uppermost segment 100c so that the upper and lower ends of the segment connection bolt 130 are exposed. As a concrete part between the block-out parts 110, a connection flange 120 formed with a vertical hole-shaped through hole so that the segment connection bolt 130 can be penetrated, and a connection flange 120 formed based on a horizontal connection surface It is inserted into the through hole of the fixing nut is fastened to the screw portion of the upper and lower ends, the fixing nut using the segment connection bolt 130 accommodated in the block-out portion 110, the lowermost segment (100a), the middle segment (100b) ), the manhole 100 is assembled and installed so that the uppermost segment 100c is integrated up and down.

The manhole 100 is downwardly inserted into the excavation hole H having a certain depth so that the uppermost segment 100c is located at the beginning of the excavation hole H.

First, as shown in FIG. 3C, the manhole cover housing 150, RC or PC support block 160, height adjustment plate 170, and anchor bolt 180 are installed around the opening (S) of the manhole 100. After that, the manhole cover 140 is seated on the inner side of the manhole cover housing 150 and installed according to the upper surface of the pavement, and the excavation hole H is closed to complete the construction of the manhole 100.

As described above, the height adjustment plate 170 is for preventing sliding while absorbing a load while finely adjusting the height of the circular ring-shaped manhole cover housing 150,

The height adjustment plate 170 made of rubber material having elasticity is further installed between the top and bottom surfaces of the RC or PC support block 160, so that the height adjustment plate 170 is expanded and the height of the manhole cover housing 150 is also finely adjusted. While making it possible, the RC or PC support block 160 can support the manhole cover housing 150 more stably, or

By using the reinforcement grid as it is as the height adjustment plate 170, it is also further installed between the top and bottom surfaces of the RC or PC support block 160, and the height of the manhole cover housing 150 is also finely constructed as the height adjustment plate 170 is expanded and contracted. While allowing adjustment, it is effective in preventing sliding.

The height adjustment plate 170 is first installed on the upper surface of the uppermost segment 100c around the opening S, and the RC or PC support block 160 is stacked.

The RC or PC support block 160 also has a function of being supported by resisting the load transmitted from the manhole cover 140 and the manhole cover housing 150, as previously described, and is reinforced in the form of a circular ring with strong rigidity. The grid 161 is arranged horizontally to be buried, so that it can effectively resist the load while minimizing its own weight, but the RC or PC support block 160 is the height adjustment plate 170 upper surface and the RC or PC support block If one or more are stacked up and down while being positioned between 160, the height of the manhole cover housing 150 can be adjusted.

Next, the manhole cover housing 150 is installed so that a horizontal connection surface is formed on the upper surface of the uppermost RC or PC support block 160, as described above, whereby the opening (S) is the manhole cover housing 150, RC Alternatively, it is exposed by the PC support block 160 and the height adjustment plate 170 and has a function of allowing the manhole cover 140 to be seated inside.

Thus, the manhole cover housing 150 is formed by stepped bolt fixing portion 151 on the outer edge, and between the inner side of the bolt fixing portion 151, a cover seating portion 152 on which the manhole cover 140 can be seated It can be seen that it is also formed as a circular ring-shaped block formed stepped.

Next, the anchor bolt 180 serves to integrally restrain the manhole cover housing 150, the RC or PC support block 160, and the height adjustment plate 170 up and down from each other, as described above, and the length Is adjusted using the coupler 183, and the head portion 181 is closed by installing the closing cap 184.

Further, as described above, in the manhole cover housing 150, a top stiffener 153 may be additionally installed on the upper surface, which is an exposed surface, in order to prevent damage to the PC block due to vehicle impact and other maintenance equipment impact.

Accordingly, the manhole cover 140 is seated on the manhole cover housing 150 using the stepped lid seating portion 152 of the manhole cover housing 150.

At this time, while fine adjustment using the height adjustment plate 170, the upper surface of the manhole cover 140 is made to match the upper surface of the pavement, such as asphalt, concrete pavement around the excavation hole (H).
