Description

Manhole structure with a trough

The present invention relates to a manhole structure, and more specifically, in the upper part of the sewage manhole for directing rainwater or domestic sewage into a sewage treatment plant, a basket-shaped needle barrel is installed to be mixed with inflow of rainwater or the like. It is related to the manhole structure having a needle tube to prevent the manhole from clogging and to easily clean the sediment by first filtering and temporarily storing the oil in the needle tube.

The present invention relates to an improvement of Utility Model Publication No. 93-3788, which is an earlier application of the applicant.

In general, sewage manholes are used in roadsides and alleys. The manhole is connected to the underground sewer pipe, and the underground sewer pipe is connected to the sewage treatment plant to send the sewage. The manhole is purified from the sewage treatment plant and flows into the general river.

The manhole is provided for drainage purposes, and once installed, it is usually used for a long time. The manhole must accept sato, fallen leaves, soil or various kinds of household waste (hereafter referred to as sediment) together with rainwater for the purpose of installation. The sediment builds up on the bottom of the manhole little by little, and over time the sediment is deposited to the top of the drain pipe formed under the manhole, which is connected to the sewer.

This means that the drain pipe is blocked and the manhole is not functioning properly.

Therefore, conventionally, the cleaning operation which removes the deposit which accumulated at the bottom part of the said manhole must be performed regularly. However, the manhole has a deep depth and a narrow interior, and it is not easy to clean as well as a phenomenon of avoiding work because it removes odorous deposits.

This honghong required manhole improvement, and it has long been recognized as one of the projects to be solved in the industry.

The applicant has proposed a manhole as shown in FIG. 9 as a prior application. The structure of the conventional manhole will be described with reference to this drawing. Reference numeral 100 denotes a manhole body having a space portion therein, 102 denotes a drain pipe integrally formed in the lower portion of the manhole body 100, and 104 denotes an acupuncture barrel that receives the deposit A. The needle barrel 104 is divided into two, forming a flange-shaped cross section, and integrally formed on the upper part of the manhole body 100.

This structure allows the manhole to be deposited in the needle barrel 104 formed on the upper part of the manhole body 100 by its own weight immediately before the sediment A flows into the manhole inner side, thereby preventing the sediment A from accumulating on the bottom of the manhole. Done.

On the other hand, when the deposit (A) is accumulated in the needle barrel 104 in a large amount and the needle barrel 104 overflows, the needle barrel 104 is formed on the upper part of the manhole body 100, so anyone can easily deposit the precipitate ( A) can be removed.

However, the manhole of the structure is a manhole body (directly by the flow rate of the rainwater flowing into the sedimentation tank 104, the sediment (A) does not fall into the needle barrel 104, when a large amount of rainwater is introduced at a time) 100) will be introduced into.

Therefore, it was not possible to completely exclude the closing of the drain pipe 102 in which sediment A mixed with rainwater or sewage is still accumulated at the bottom of the manhole.

An object of the present invention is to provide a manhole structure that solves the problems of Utility Model Publication No. 93-3788, filed and filed by the present applicant.

According to one embodiment of the present invention to achieve the above object, the upper inside of the manhole is settled in the pit is formed a plurality of sewage induction hole, the upper side of the pit is in the manhole to which the drain plate for introducing rain water is seated In the sedimentation barrel, a locking jaw is formed at a lower side, and a separation bottom plate is seated on the locking jaw so as to be detachable, and the separation bottom plate has a plurality of fixing protrusions inserted into the sewage guide hole.

In addition, according to another embodiment of the present invention, a manhole body having a partition side formed in the upper inner side, a plurality of acupuncture passages having a plurality of inclined portions having a plurality of drainage holes in the lower portion is inserted detachably in the upper portion, and Provided is a manhole structure having a mandibular barrel including a manhole body and a drain plate seated on an upper side of the mandrel and folded by a hinge portion.

As such, the present invention further improves the structure of the needle barrel installed in the manhole of the applicant of the present application, so that it can be used very easily when cleaning the needle barrel regularly, thereby preventing waste of manpower and reducing the maintenance inspection cost of the manhole. It is a useful design that can work.

The drain plate 20 is assembled to the first stepped portion 21, and the needle bar 30 is assembled to the second stepped portion 14, respectively. Although the manhole body 10 shown in FIG. 1 has a square shape, it is not necessarily limited to such a shape, for example, may be cylindrical.

Reference numeral 16 denotes a drain pipe integrally formed under the manhole body 10.

Referring to Figure 3, the drain plate 20 is installed at the same height as the height of the ground. A plurality of holes are formed in the drain plate 20. This hole can be manufactured in various forms as the sewage induction hole 22 for introducing rainwater into the manhole body 10. Moreover, this drain board 20 is produced corresponding to the shape of the manhole main body 10. FIG. In the present invention, a rectangular shape is achieved. In Fig. 3, reference numeral B denotes a conventional sewer pipe connected to the drain pipe 16.

The needle trough 30 forms a basket shape as a whole. The upper part of both side walls is formed with a plurality of comb-shaped sewage guide holes 32, and the upper part is formed in the shape of a flange 34 so as to be caught by the second step 14, and on both sides of the other side wall of the operator A handle groove 36 is provided to allow a hand to enter. In addition, at least one drain hole 38 is formed at the bottom to prevent the sewage from remaining in the needle barrel 30.

According to the first embodiment of the present invention of such a canter, when the sewage, such as rain water flows into the manhole body 10 through the sewage guide hole 22 of the drain plate 20, the drain plate 20 and the manhole body ( Since the needle pipe 30 is installed between the drain pipes 16 of 10), the primary needle pipe 30 is introduced into the needle pipe 30. Subsequently, the sewage overflowing in the immersion barrel 30 falls freely downward as it is through the sewage induction hole 32 and flows out into the sewer pipe B through the drain pipe 16. In the sewage induction hole 32, sediment, such as fallen leaves, is first filtered out and deposited in the immersion barrel 30.

On the other hand, the sediment is dropped into the needle barrel 30, a large amount of precipitate (A) is deposited in the needle barrel (30) is filled up to the sewage induction hole 32, the handle groove portion 36 of the needle barrel (30) The cleaning is carried out by lifting the needle barrel (30).

In this figure, reference numeral 50 denotes a manhole body (which is composed of upper and lower bodies 50a and 50b, of course), 60 denotes two sets of drain plates, and 70 denotes two separate needles. The manhole body 50 has a structure substantially the same as that of the first embodiment, but since the needle barrel 70 is formed in two, a structure for receiving them, for example, a partition wall partitioning the upper center ( 51) and the two needles 70 are separated and installed. The bottom plate of the needle barrel 70 is formed to be inclined, and at the same time, a drain hole 78 is formed near the center thereof.

The drainage plate 60 is divided into a first drainage plate 61A and a second drainage plate 61B, which are hinged through a hinge portion 63. The hinge portion 63 is placed on the partition wall 51 when the drainage plate 60 is assembled on the manhole main body 50, thereby preventing it from being folded without permission. Reference numerals 52 and 54 denote first and second step portions, 56 denote drainage pipes, 72 denote sewage guide holes, and 76 denote handle groove portions.

The second embodiment of the structure has the same function as the first embodiment, but the needle barrel 70 is composed of two pieces and the drain plate 60 can be folded through the hinge portion 63. The structure is different.

In this second embodiment, since the sedimentation barrel 70 is divided into two parts, the weight of the sediment A precipitated in each of the salivary barrels 70 is light, which is very convenient for cleaning. If the structure can be folded because of the small volume, good portability and installation workability.

Figure 5 is a cross-sectional view showing another embodiment of the needle bar of the present invention, Figure 6 is a partial cutaway perspective view of the separation bottom plate of the present invention, Figure 7 is an important part for explaining the fixed state of the separation bottom plate of the present invention 8 is an enlarged cross-sectional view, and FIG. 8 is a cross-sectional view for explaining a separation bottom plate of the present invention. In these figures, reference numeral 80 denotes a needle. This needle barrel 80 has a separating bottom plate 82 of a structure in which the bottom plate is freely poured. Moreover, it has the handle groove part 86 of 1st, 2nd Example. The handle 86 is configured to be rotatable about a fixing pin 86 '.

The bottom of the needle barrel 80 is penetrated, but the inner edge portion is formed with a locking step 81 so that the separation bottom plate 82 spans. Two fixing protrusions 84 are integrally formed on one side of the separation bottom plate 82. The handle 86 is configured to be folded to the left and right as shown by the arrow in FIG. Therefore, in the installation state of the usual, when the operator pulls the handle 86 at the time of cleaning, it is unfolded as shown in FIG. 5, and the unfolded handle 86 is pulled upward to settle in the needle barrel 80 This will remove the precipitate (A). Reference numeral 83 is a rib formed in the longitudinal direction of the needle barrel 80, and 85 is a sewer drain hole.

The separating bottom plate 82 is designed to prepare for a sudden case (a shower pouring in a large amount in a short time). The separating bottom plate 82 forms two fixing protrusions 84 at predetermined portions, and the fixing protrusions 84 have two elastic protrusions 84a and 84c having elasticity rounded outwards. The elastic protrusions 84a and 84c form groove portions 84b at appropriate intervals.

The separating bottom plate 82 is normally caught in the locking jaw 81 of the needle barrel 80 in the state as shown in Figure 5 to serve as the bottom plate of the needle cage 80.

The separating bottom plate 82 is used in a situation where the rainwater can not be drained through the sewage guide hole 85 when a large amount of rain suddenly falls into the immersion barrel 80. That is, when the manhole overflows due to flooding or the like, as shown in FIGS. 6 to 8, in the present invention, the bottom of the trough 80 is composed of a unique separation bottom plate 82 that can be separated from the trough 80. Since the separation bottom plate 82 is removed from the needle barrel 80, the needle barrel 80 and the inside of the manhole bodies 10 and 50 communicate with each other to smoothly drain a large amount of rainwater.

Next, the case where the said separation bottom plate 82 is fixed to the side wall of the needle barrel 80 is demonstrated. Normally, as shown in FIG. 5, the lower portion of the dipstick 80 serves as the bottom plate of the dipstick 80, and when the separation bottom plate 82 is separated as necessary, as shown in FIG. In order to prevent the loss of the separation bottom plate 82 is fixed to the side wall of the needle cage (80). That is, the elastic bottoms 84a and 84c of the separation bottom plate 82 are elastically inserted between the sewage guide holes 85 of the needle barrel 80 so that the separation bottom plate 82 can be safely stored. . Reference numeral 83 is a column between the sewage guide holes 85, and 83 'is a rib.

As described above, the manhole structure having the trough of the present invention provides a trough in the upper part of the normal manhole, so that the sediment mixed with rainwater or domestic sewage is precipitated by the first natural fall type, so that the sediment does not reach the bottom of the manhole. The drainage pipe connected to the sewer pipe is not blocked, and the structure of the sedimentation pipe is further improved, so that it can be used very easily when cleaning the water storage tank on a regular basis, thereby preventing waste of manpower and reducing the cost of maintenance inspection of the manhole. It is a useful design that works.
