Description

Manhole

The present invention relates to a manhole cover assembly, and more particularly, to a manhole cover assembly in which concrete filling the periphery of an assembly through a vertical end and a discharge hole does not interfere with height or slope correction of the iron.

A manhole is an underground facility that provides a work space necessary for maintenance of water supply and drainage pipes, communication cables or gas pipes buried in the underground of a road surface. The basic configuration is a manhole body mainly made of concrete and a work space formed therein, A manhole cover for blocking an entrance formed at an upper portion thereof, and an iron cover provided at an upper portion of the entrance for installing a manhole cover on the manhole body.

The construction of the manhole should be such that the manhole cover is not excessively depressed or protruded from the surrounding road surface for the safe walking of the pedestrian and the safe running of the vehicle.

However, it is difficult to construct the manhole cover so as to have the same plane as the surrounding road surface due to various factors such as the condition of the construction site (inclined road surface, etc.) and poor construction.

Even if a good construction is performed, the above-mentioned depression or protrusion occurs due to various causes such as impact applied repeatedly by the vehicle or ground subsidence around the manhole, and repair work is performed to match the height of the manhole cover with the ground It is also required.

Various prior arts have been disclosed which can adjust the height or inclination of the manhole cover in order to facilitate the initial construction or repair work. The present applicant has also proposed a manhole cover assembly capable of adjusting the height or inclination of the manhole cover, Patent No. 10-1707609 (registered date: Feb. 10, 2017).

However, if the surrounding of the assembly is filled with concrete at the time of construction, the concrete is firmly fixed to the earth retaining wall (4), and the liquid residue of the concrete penetrates into the gap of each member and evaporates, The problem of making it difficult to correct the height or the inclination of the railway 1 when repair work is carried out for reasons such as subsidence after the construction.

Further, there is a fear that the side wall pressure acts on the retaining wall 4 of the manhole cover assembly due to the environmental change around the assembly after the construction, and the retaining wall 4 is collapsed.

A problem to be solved by the present invention is to provide a manhole struc- ture assembly which is not hampered by the work of correcting the height or tilt of the iron due to the concrete filling the periphery of the assembly, and also has excellent durability.

According to an aspect of the present invention, there is provided a manhole cover assembly including a manhole cover on which a manhole cover is placed; A bottom flange formed on the lower end of the base body and protruding outwardly and a vertical end concentric with the base body and disposed on the outer side of the base body and having an end fixed to the lower flange, A base portion fixed to an entrance of the manhole body; An adjuster comprising a plurality of fixtures radially disposed and fixed to the steel bar, a support ball provided inside each fixture, and an adjustment bolt fixed to the support ball at an upper portion and fixed to the base portion with a nut; And a cover including a plurality of unit covers fixed to and mutually juxtaposed to the steel pegs; And the unit cover is raised and lowered by rotation of the adjustment bolt in a state of being disposed in a receiving space between the base body and the vertical end.

Further, the manhole cover assembly of the present invention is characterized in that a plurality of discharge holes are formed on the circumferential surface of the base body.

In addition, the manhole cover assembly of the present invention is characterized in that the unit cover is provided with a step at both ends thereof, and the step is provided so as to overlap with the adjacent step.

In addition, the manhole core assembly of the present invention is characterized in that the lower end of the iron core has a sloped end inclined downwardly toward the bottom, and the unit cover is rotatably fixed to the outer circumferential surface of the sloped end.

According to the manhole-cover irons assembly of the present invention, the concrete is fixed to the cover while suppressing the flow of the concrete filling the periphery of the assembly through the plurality of discharge holes formed in the circumferential surface of the base body and the vertical end concentrically arranged on the outer side of the base body And a part of the inflowed concrete is rapidly discharged, so that the maintenance work of the assembly according to the present invention is improved because the work of correcting the height or the inclination of the iron is not obstructed by the concrete residue at the time of repair work.

3, 4 and 5, the present invention includes a pillar 10 on which a manhole cover A is placed, a base 20 fixed to the entrance b of the manhole body B, 10 and the base portion 20 and the cover 40. The height or the degree of inclination of the pillar 10 is adjusted by adjusting the bolts of the adjusting portion 30 so that the manhole cover A can be made to coincide with the road surface, and the height or the inclination of the pillar 10 can be easily corrected even if repair work is required after the periphery of the assembly is filled with concrete.

A first embodiment of the present invention will now be described in detail with reference to the accompanying drawings. First, a pillar 10 receives a manhole cover A in an inner upper space. The pillar 10 includes a hollow cylindrical pillar body 11, An inner end 13 protruding from the inner circumferential surface of the neck 11 and an inclined end 15 formed at the lower end of the neck 11.

The manhole cover A is placed on the upper surface of the inner end 13 and the fixing member 31 of the adjusting part 30 to be described later is fixed to the lower surface.

The inclined end 15 is formed in such a manner that its inner diameter becomes smaller toward the lower side and the unit cover 41 of the cover 40 to be described later is fixed to the outer circumferential surface of the inclined end 15. The reason why the unit cover 41 is sloped will be described later.

The base portion 20 has a hollow cylindrical base body 21 having a diameter corresponding to the entry / exit port b, An upper flange 23 formed at the upper end of the main body 21 and protruding inwardly, a lower flange 25 formed at the lower end of the base main body 21 and projecting outwardly, And a plurality of discharge holes 29 formed on the circumferential surface of the base body 21. The vertical end 27 is fixed to the lower flange 25 and the discharge hole 29 is formed on the outer circumferential surface of the base body 21. [

One side of the adjuster 30 is bolted to the upper flange 23 and a plurality of fastening holes are formed radially.

The lower flange 25 has a configuration for fixing the base portion 20 on the entrance b. The lower flange 25 and the plurality of fastening holes for fastening are radially formed.

The vertical end 27 is a structure for preventing the concrete from being fixed to the cover 40 while suppressing the inflow of concrete into the manhole core assembly when the periphery of the manhole core assembly is filled with concrete, The cover 40 disposed in the receiving space s between the vertical end 27 and the base body 21 in a state in which the concrete is hardened and fixed on the outer circumferential surface of the cover 27 can be freely moved And then goes up / down.

In addition, since the vertical end 27 mainly covers the side pressure by the concrete filled around the manhole cover assembly, it is possible to effectively protect the inside cover 40 from the side pressure by the concrete.

As described above, the discharge hole 29 is formed so as to prevent the remaining concrete after the liquid of the concrete from penetrating into the space (s) or the gap between the members to prevent the control unit 30 from starting. The liquid material infiltrated through the accommodation space s or the like is discharged into the manhole main body B through the discharge hole 29 and the entrance b.

The adjusting unit 30 is configured to adjust the height or the degree of inclination of the steel pile 10. The adjusting unit 30 includes a plurality of fixing holes 31 radially arranged and fixed to the back surface of the inner side 13, The ball 33 and the upper end thereof are fixed to the support ball 33 and the lower portion thereof is made of an adjusting bolt 35 fixed to the upper flange 23 with a nut.

The inclination of the steel bar 10 is adjusted by adjusting the fixing of the nut of the adjustment bolt 35 and adjusting the height of the bar 10 while varying the height of each adjustment bolt 35.

The fixture 31 and the support ball 33 are configured to stably support the steel strip 10 when the steel strip 10 is installed at an inclined position. The inside of the fixture 31, which is in contact with the support ball 33, A hemispherical groove corresponding to the ball 33 is formed.

The cover 40 prevents a gap or the like between the pillar 10 and the base portion 20 from being filled to prevent the concrete or the like filling the periphery of the assembly from flowing into the gap between the assembly members through the clearance, And is composed of a plurality of unit covers 41 mutually juxtaposed as a structure for facilitating the adjustment.

Each unit cover 41 is fixed to the inclined end 15 through a fastening bolt 45 in order to stably prevent the vertical gap width of the gap which varies depending on the height and the inclination of the rail 10, And is raised / lowered together with the steel bar 10.

A step 43 is formed on both ends of the unit cover 41. The step 43 has a structure in which the unit covers 41 are overlapped with the adjacent step 43, More effectively.

On the other hand, since the unit cover 41 is rotatably fixed to the outer circumferential surface of the inclined step 15 through the fastening bolt 45, the assembly is inclined at a predetermined angle? The unit cover 41 is maintained in a vertical state even if the steel bar 10 is inclined at the angle? In the case of being installed on the road surface E, and the unit cover 41 is not vertically integrated with the cylindrical cover, It is possible to prevent the unit cover 41 from moving up and down in the vertical direction without being interfered with the inner wall of the accommodation space s, that is, the vertical end 27 or the base body 21, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
