Description

Manhole structure

The present invention forms a hume through portion inside the rim of a sphere manhole located at the bottom of the manhole structure, and also concentrically inserts rings having different diameters on the outer and inner surfaces of the sphere manhole where the hume through portion is formed. After selecting a ring suitable for the diameter of the fume pipe so that the fume pipe penetrates through the fume pipe part, it is possible to prevent cracks and burnout occurring in the process of drilling holes therein and to guide the fume pipe to the correct position. After the fume pipe is installed, the adhesive mortar is injected into the remaining space of the fume pipe through the manhole structure to completely prevent leakage while improving the water tightness by eliminating the empty space around the fume pipe.

In general, a manhole is a hole made by humans to inspect, repair, or clean water pipes, sewer pipes, and wires in the ground. For example, in the case of a sewer manhole, various sewage and debris are filtered out. It will be able to flow smoothly and keep the pipes from clogging.

In the conventional sewer manhole structure, as shown in Figure 5, the block-shaped manhole (10a, 10b) is made of a plurality of stacked, and the bottommost contact with the bottom surface sphere manhole (10a), the sphere manhole ( 10a) The manhole stacked on the upper side is called a stacking manhole 10b, and the topmost manhole 10b is integrated with the manhole cover 20.

The manhole cover 20 has a through-hole 22 and a handle 24 which a person can enter, and the upper and lower edges of the impression manhole 10b have coupling grooves 12 and protrusions 14 having an entire edge. Is formed over or partially formed to be able to maintain a certain degree of engagement with the stack between the impression manhole (10b), the fastening hole 16 is formed on the outer engagement side of each of the stacked manhole (10b) Bar, the bracket 50 is padded and fastened by the fastening means 18 it is possible to further solidify the coupling state.

Of course, only the protrusions 14 are formed in the case of the impression manhole 10b which is integrated with the manhole cover 50 among the manholes 10a and 10b described above, and in the case of the concrete manhole 10a, only the coupling groove 12 is formed. do.

Next, in order to penetrate the fume pipe 60 to the sphere manhole (10a) by using a cutting means on one side and the other end surface of the sphere manhole (10a), the same hole as the diameter of the fume pipe (60), and the fume pipe (60) After passing through the hole, the joint is joined to concrete, the illustrated manhole structure 70 is completed.

However, when constructing the conventional manhole structure 70 as described above, the following matters regarding the spherical manhole 10a through which the fume pipe 60 penetrates, the spherical manhole 10a is made of a material such as concrete. In order to penetrate the spherical manhole 10a having such a material, the fume pipe 60 penetrates the hole as much as the diameter of the fume pipe 60 on the through preliminary projection. Done.

This crack is initially only a fine crack, but once the crack is formed to expand over time, after a period of time will cause the risk of burnout and leakage of the concrete manhole (10a), if the manhole In the case where the structure 70 is large, since a very large force must be applied in order to drill the hole in the spherical manhole 10a, it can be said that cracking is inevitable.

In addition, in view of the above problems, the thickness of the edge of the sphere manhole 10a may be reduced by reducing the strength of the edge of the sphere manhole 10a only in the formation range of the hole to be drilled in the sphere manhole 10a. After it is made, the periphery is filled with concrete so that watertightness is achieved, and there is an inconvenience in that a separate member such as formwork is provided to fill and cure concrete, and it is essential to suppress cracking. Since it did not provide a solution, there was a great difficulty in achieving watertightness for the part where the fume pipe 60 was installed.

The present invention has been devised in view of the above circumstances, and has an empty space of a fume through-hole formed inside the rim of the sphere manhole to have artificial weaknesses, and on both the outer and inner surfaces of the sphere manhole through which the fume-through is formed. By inserting a ring with the same diameter of the fume pipe to be used, it is possible to prevent cracks or burns that occur around the fume through-holes in the process of drilling holes to penetrate the fume pipes, and also to guide the holes in the correct positions. The purpose of the present invention is to provide a manhole structure that can work very conveniently by injecting adhesive mortar into the empty space of the hume pipe through which the fume pipe is penetrated to prevent water leakage while improving watertightness. have.

Hereinafter, the configuration and operation of the present invention will be described in detail based on the drawings.

The present invention for achieving the above object is a lower end of the sphere manhole (10a), a plurality of impression manhole (10b) is stacked above the height of the space to be installed, the upper and lower sides of the coupling groove 12 and Protruding portion 14 is formed, the manhole structure in which the fastening hole 16 is formed in the upper and lower side of the outer surface is possible to be laminated by the combination of the bracket 50 and the fastening means 18,

The spherical manhole 10a in which the fume through-hole 30 is formed to include a range through which the fume pipe 60 is to be penetrated, and the fume through-hole 30 is formed inside the edge of the spherical manhole 10a. On the inner and outer sides of the), a plurality of rings 40 having the same diameter as the hume pipe 60 is inserted in a concentric circle, the empty space of the hume pipe penetration portion 30 through which the hume pipe 60 is penetrated. Adhesive mortar is injected into the water, characterized in that the leakage and hermeticity is maintained.

1 and 2 are a plan view of a separate perspective view and a concrete manhole showing an example of a manhole structure according to the present invention, and FIGS. 3 and 4 are longitudinal cross-sectional views and use state diagrams of the manhole structure, respectively. The impression manhole (10b) formed integrally with the manhole cover (20), which is formed at the bottom, and has a stacking impression manhole (10b) formed at the center and a through hole (22) and a handle (24) formed at the top. Laminated in turn.

Of course, the coupling grooves 12 and the protrusions 14 are formed on the upper and lower edges of the manholes 10a and 10b, respectively, as in the prior art, thereby maintaining the coupling state when the stacking is carried out, and the manhole structure 70 is further formed. To increase the height can be further adjusted by stacking the stacking manhole 10b for stacking.

In more detail with respect to the sphere manhole (10a), in the upper edge portion of the hume pipe through portion 30 is opened from the top to the bottom in a preferred embodiment of the present invention, for example, formed in three places, the fume pipe In the upper edge portion excluding the through portion 30, the coupling groove 12 is recessed to a certain depth, and the outer and inner surfaces of the spherical manhole 10a in the region where the fume through portion 30 is formed have a diameter. A plurality of different rings 40 are inserted into concentric circles.

In particular, the hume through portion 30 is an empty space from the upper end to the lower end of the sphere manhole (10a), but is not an opening to the lower end of the sphere manhole (10a) includes a place where the ring 40 is formed. The space is only enough to the bar, as shown in the lower portion of the hume through portion 30 is formed to be a smooth curved surface similar to the shape of the ring (40).

In addition, the outer surface and the inner surface of the spherical manhole (10a) formed with the hume through portion 30 is thinner due to the formation of the hume through portion 30, so as to act as a surface vulnerable to external impact This makes it very easy to drill holes.

On the other hand, the ring 40 is inserted into the outer surface and the inner surface of the sphere manhole (10a) of the weak surface, so as to have the same diameter as the diameter of the fume pipe (60) penetrating the sphere manhole Since the fume pipe 60 penetrating 10a has various diameters, the ring 40 is also arranged concentrically while having various diameters.

In addition, as shown in Figure 2, the ring 40 is preferably inserted with a width of at least 2/3 or more compared to the thickness of the inner surface and the outer surface of the sphere manhole (10a), in the case of the inner surface The inner side, and in the case of the outer side, is formed to be biased toward the outer side so that the operator can visually identify the diameter and position of the ring 40.

Now, the operation of the manhole structure according to the present invention will be described.

First, the fume pipe 60 to be used is selected and then the inner part of the ring 40 is drilled using a separate cutting means based on the ring 40 suitable for the diameter of the selected fume pipe 60. , The worker drills a hole while looking at the diameter and position of the ring 40 seen on the outer and inner surfaces of the sphere manhole 10a, so that the work can be performed very easily.

In addition, the thickness of the outer surface and the inner surface is relatively thin due to the formation of the fume through portion 30, it is very easy to make a hole in the outer surface and the inner surface with a small force, even using a cutting means Even if there is a risk of cracking out of the hole due to the excessive force applied, the ring 40 is located at the outermost part of the hole to be drilled and blocks the occurrence and expansion of such a crack, thereby eliminating the concern. do.

On the other hand, after the hole as described above to pass through the fume pipe 60 and the fume pipe 60 is installed through the fume through portion 30, the adhesive mortar to the remaining empty space of the fume through portion 30 Will be injected.

Here, although the adhesive mortar is an essential component of the present invention, even if the diameters of the fume tube 60 and the fume through portion 30 are set to be the same, there are some differences due to manufacturing errors and the like. When the remaining space of the hume through portion 30, except for the portion through which is left as it is, itself acts as a relatively weak portion against the external force, the adhesive mortar through the fume tube 60 and the fume through as described above When injected into the empty space of the connection portion and the hume through portion 30 of the part 30 can be eliminated this concern, after the injection of the adhesive mortar and vibrated by vibrator, the fume pipe (60) Since the gap between the) and the fume through portion 30 can be achieved and leaks and airtight, it is not necessary to provide a formwork as in the prior art it is possible to further promote the convenience of work.

Therefore, to prevent leakage and watertight, and to prevent the occurrence of cracks and expansion to complete the manhole structure that can be carried out conveniently.

As seen above, according to the manhole structure according to the present invention, while forming a hume through portion inside the rim of the sphere manhole, the diameter of each of the outer side, or both the outer side and the inner side of the sphere manhole formed with the hume through portion By inserting the ring with concentric circles, it is very easy to position and drill holes for penetrating the fume pipe, and to prevent the occurrence and expansion of cracks generated around the hole, and above all, the adhesive mortar between the fume pipe and the fume through part. By injecting to improve watertightness is effective to prevent leakage.
