Description

Underground construction of roads {UNDERGROUND LAYING CONSTRUCTION OF ROAD}

The present invention is to produce a rectangular concrete box so as to distribute the sewage and rainwater to the underground buried structure, and to raise and lower the inner side so that it can be processed smoothly when a large amount of rainwater due to heavy rain occurs during the summer rainy season It relates to an underground buried structure of the road to the wall by lifting and fixing to the inner wall surface.

Various underground buried structures are installed on the road, especially in the underground of the road, sewage structures made by laying concrete with underground buried, manhole structures for checking the sewerage, drains for draining rainwater and sewage to the sewer structures. Various concrete structures are buried in the ground, such as structures, communication line structures for transporting telephone lines and communication lines, and water supply structures for supplying water supplies to buildings and houses.

Currently, many culverts made of the above-mentioned concrete structures as ready-made products in factories are used. The culverts (square concrete boxes; CULVERT) increase convenience in construction, shorten construction period, and maximize traffic of vehicles on the road. While used to recover quickly, in particular the culverts are often made of rectangular and circular structures.

The sewage structure is made to be used as a rectangular structure, wherein the sewage structure is buried in the ground in favor of a product with improved water tightness for the joint and a high strength, the sewage structure is a sewage structure rainwater. Even if it rains a lot and rains, rainwater does not collect on roads and residential areas, and it is used for flood prevention.

The sewage structure is a structure used to transfer the sewage and wastewater generated in homes and factories to a sewage treatment plant. Generally, the name "sewer conduit" is used. There is a combined sewer system. Generally, sewage, wastewater and rainwater discharged from homes and factories are called "sewage," which consists of sewage pipelines, sewage treatment facilities and sludge treatment facilities that collect these sewage.

The "sewage pipe facility" is composed of sewage pipes and pumping stations, and the sewage pipe is a generic term of facilities including conduits, sewers, storm drains, manholes, storm drains, earthenware and connecting pipes. The wastewater and rainwater are collected and run down to the treatment plant or discharged water, and the sewage pipe is made of a structure and material that can withstand external pressure.

1 is a view showing a conventional general underground buried structure, the sewage structure (1) which is underground buried, the rubble layer (3) is formed at the bottom so as to be in contact with the bottom surface (2) and the rubble layer (3) The base concrete plate 4 is installed on the upper portion of the base concrete plate 4 is installed by mounting a rectangular concrete box (CULVERT) (5) on the top.

The rectangular concrete box 5 is constructed so that a plurality of lines are arranged in a line in the longitudinal direction, and the joint portion is subjected to a coating process by inserting a sealing material and a finishing concrete.

In addition, the rectangular concrete box 5 may be constructed in a structure in which a wire steel wire is inserted and tensioned through an insertion hole at a corner when a plurality of rectangular concrete boxes 5 are constructed in a line in the longitudinal direction.

In the case of the underground concrete box formed in the above-described structure, the rainwater and sewage flows separately in the case of the sewer type sewer, and the rainwater and the sewage flows together inside the rectangular concrete box in the case of the combined sewer.

However, in case of heavy rain, such as during the rainy season, if rainwater is completely filled inside the rectangular concrete box, rainwater generated on the road will accumulate on the road as it is, resulting in frequent car collisions. There is a problem in that the resulting human injury.

The present invention is to solve the above problems, the present invention, by distributing the sewage and rainwater to produce an expandable rectangular concrete box and to dismantle the inner wall, lifting wall when the rainwater is increased to a large capacity, such as rainy season It is an object of the present invention to provide underground construction structures for roads that allow smooth transportation of sewage and rainwater.

In the above-described lifting and lowering walls 20 and 20 ′, the guide members are omitted for the sake of explanation in view of the relationship between the guide members having different types.

FIG. 14 is a perspective view of a manhole installed between longitudinal directions of the expandable rectangular concrete box of the present invention, and FIG. 15 is a view illustrating a state in which the manhole of FIG. 14 is embedded in the ground.

As can be seen in Figure 14, the manhole 70 is made of a structure that can be combined with the expandable square concrete box, the manhole 70, the sealing member seated in a rectangular shape on the upper surface of the manhole body 71 A groove 72 is formed, and a rectangular sealing member 73 is formed in the sealing member seating groove 72, and the compression type seating member 74 made of urethane material on the rectangular sealing member 73. Is installed, the upper plate 75 made of cast iron is installed on the upper portion of the compression-type seating member 74, the manhole cover 77 on the lid seating portion 76 of the upper plate 75 It is a structure to be combined.

That is, the manhole 70 is a state in which the rectangular sealing member 73, the compression type seating member 74 and the top plate 75 are sequentially loaded in the sealing member seating groove 72 of the manhole body 71. The anchor bolt 80 is coupled through the bolt hole 78 and the nut 81 is fastened to install as an integral structure.

As can be seen in Fig. 15, the manhole 70 is connected to the drain side port 91 installed adjacent to the straight side port 90 in the state buried in the ground of the road and the drain hole on the side by the drain pipe The rainwater is usually transported separately, and when heavy rain is poured, such as during the rainy season, the lifting and lowering wall 20 "coupled to the inner wall of the manhole is elevated to the upper portion, and the sewage and rainwater are mixed and transported.

As can be seen in the above-described configuration, a plurality of the expandable rectangular concrete box 10 is used is connected in the longitudinal direction, the manhole at a constant distance between the plurality of expanded rectangular concrete box 10 is connected 70 is installed to perform the check operation on the expandable rectangular concrete box (10).

In FIG. 15, only the state in which the manhole 70 and the drainage side opening 91 are coupled is shown. In fact, the coupling structure of the manhole 70 and the drainage opening 91 is equally applied to the expandable rectangular concrete boxes 10 and 60. In the drawing, the drawing is not shown.

The expanded rectangular concrete box (10) (60), the sewer and rainwater can be used differently depending on the season in a state in which the sewer is installed separately, if the rain falls less, such as spring, autumn and winter, When the walls 20 and 20 'are lowered to the lower side, and heavy rains such as summer, workers enter the expandable rectangular concrete box 10 and 60 through the manhole 70 and are installed therein. The rainwater generated on the road can be easily transported to the sewage treatment plant in the state of elevating and descending the walls 20 and 20 '.

The effects according to the configuration and operation state of the present invention described above will be described.

Underground structure of the road of the present invention, by using the expandable rectangular concrete box can be transported sewage and rainwater generated in buildings and houses separately, in particular rainwater can be transferred to the river or sea by installing a separate structure separately. The effect of improving the water environment can be obtained.

In addition, in the case of using the above-described expandable rectangular concrete box, since the structure has a structure different from the conventional rectangular concrete box, the rainwater generated on the road can be processed quickly, so that the vehicle can run smoothly. This prevents a car crash that occurs frequently during the rainy season, and thus has the effect of preventing safety accidents.
