Description

Metalized Manhole and it's Mounting Method

This proposal relates to manholes that allow the underground pipes to be inspected and repaired. In particular, the weight of the buried pipes can be easily and easily installed for existing pipelines that have already been buried. Or to a ready-made manhole that prevents vibration from being transmitted directly.

Conventional manholes are recognized as underground structures that can be installed in the ground along the road where buried pipes are buried, so that the buried pipes can be inspected or repaired. Most of these manholes have been constructed as cast-in-place concrete. .Explaining the construction method of the manhole by the site-casting concrete method as described above in detail, first, the foundation is formed by placing concrete on the floor surface excavated by excavating the ground of the corresponding construction location, and then piped on the foundation floor. Cylindrical manhole formwork is installed around the buried pipe, and uncured concrete is cast and hardened in the installed manhole formwork, so that the buried pipe and manhole formwork are united. According to the construction method of the manhole, the first manhole formwork The work load is excessively increased to assemble and dismantle the Not only does it cost excessive construction costs, but it also takes considerable form preservation periods until the manholes are cured and the construction period is extended, increasing the inconvenience of vehicles or pedestrians traveling on the road. Second, when installing the manhole formwork, it has the construction conditions that must be destroyed in a huge size so that not only the installation area of the manhole formwork but also the worker can freely install the manhole formwork. In addition to the new pipelines that newly bury buried pipes, it is almost impossible to construct manholes in existing pipelines where buried pipes are already buried. The third manhole was placed on the buried pipe so that it could be integrated. In view of the fact that the weight of the manhole itself is not only directly transmitted to the buried pipe, but also because the vibration generated in the vehicle traveling on the road is transmitted to the buried pipe through the manhole, the buried pipe is constantly applied from the manhole. There was a serious problem of losing weight load and repeated vibration and eventually causing cracks or damage to the children due to cracks.

This proposal simplifies the work process of installing the first manhole, greatly improving the construction efficiency. Second, the buried pipes allow the manholes to be installed on the existing pipelines. It aims to provide a ready-made manhole that makes it possible to maintain the original shape and function without damaging the third buried pipe by weight load or vibration.

As shown in Figs. 1 and 2, the ready-made manhole 1 of the present invention has a cylindrical cross-sectional shape, the upper part of which is blocked, and the lower part of the manhole body 10 is formed so as to communicate with the upper part of the manhole body 10. Buried pipe assembly groove 30 is formed as a curvature corresponding to the outer diameter of the buried pipe (2) on both sides of the lower end of the manhole main body 10 is installed so that the worker can enter the inside of the manhole body ) And the supporting hardware 40 on both sides which are installed to hold the lower ends of both sides of the manhole body 10 in a horizontal manner.

As shown in Fig. 3, the ready-made manhole of the present construction, which is configured as described above, burrows so that the buried pipe 2, which is already buried in the ground of the work position, is completely removed so that the discarded concrete 3 is placed on a horizontal floor surface. Placing and installing the supporting hardware 40 of the ready-made manhole (1) side by side on both sides centering on the buried concrete (3) on the cast concrete, and buried pipe assembly grooves on the supporting hardware (40) on both sides While placing the ready-made manhole (1) in which 30 is formed, the buried pipe (2) is inserted into the buried pipe assembly groove of the ready-made manhole with a predetermined gap therebetween, and the buried pipe (2) and the ready-made manhole (1) are installed. And it is constructed by placing the fixing concrete 4 so that the supporting hardware 40 is integrated.

In other words, the ready-made manhole of the present invention has an access passage 20 at the upper part of the manhole body 10 having an empty space therein, and the buried pipe assembly grooves 30 at the lower part thereof, and the manhole body 10 of The lower both sides are configured to support the required height as the supporting hardware 40, so that the buried pipes can be easily and easily installed for the existing pipes already buried. It is to prevent direct delivery.

According to the ready-made manhole of this paper, the first work takes a lot of time and can eliminate the cumbersome formwork, thereby reducing the cost of work by reducing the number of unnecessary workmen, and shortening the construction period to pass the road. Eliminates inconveniences of vehicles and pedestrians. Secondly, manholes can be installed in existing pipelines where abnormalities occur in buried pipes, thereby reducing the burden of maintenance by easily inspecting and repairing existing pipelines. Since the buried pipe is prevented from being damaged by avoiding the weight load or vibration applied from the buried pipe, the buried pipe is extended and the life of the buried pipe can be continuously maintained.

The manhole body 10 is a cylindrical cross-sectional shape having an empty space therein is formed so that the upper portion is blocked and the lower portion is open, which can repair and check the existing pipeline in which the buried pipe 2 is already buried in the ground. Ensure a working space.

In the embodiment of the present disclosure, the manhole body 10 is exemplified as being made of cast iron, but it is revealed that it may be made of concrete or synthetic resin as needed.

In addition, the manhole body 10 has a plurality of fixed anchors 11 protruding horizontally formed at a predetermined position of the outer surface of the lower end, as shown in Figs. 1 and 3, the ground manhole 1 of the present It is preferable to increase the unity with the fixing concrete 4 as the fixed anchor 11 formed in the manhole body 10 at the time of embedding.

Here, the manhole body 10 has a ladder (12) installed in the vertical direction long to be connected to the access passage 20 at a predetermined position inside the manhole body 10 to enter the working space inside the manhole body 10 The access passage 20 is installed in communication with the upper part of the manhole body 10 to allow the worker to freely enter and exit the access passage 20 in the embodiment of the present disclosure. ) Is formed by drilling a passage hole 21 in the upper surface of the manhole body 10, and has a cover plate 23 formed to be detachable to the lid support 22 installed on the upper portion of the passage hole, The cover plate 23 is covered with the cover plate 22 to seal the passage hole 21, and during maintenance and inspection of the buried pipe 2, the cover plate 23 is opened from the cover plate 22 so that the operator Inside the manhole body 10 through a hole 21 The buried pipe assembly grooves 30 are formed at both sides of the lower end of the manhole body 10 so that the buried pipe 2 is exposed to the inside of the manhole body 10. The buried pipe assembly groove 30 is important to form a curvature corresponding to the outer diameter of the buried pipe (2) on both sides of the lower end of the manhole body (10). The reason is that the gap between the buried pipe assembly groove 30 and the buried pipe 2 can be assembled uniformly, so as to help to install the ready-made manhole 1 precisely. As shown in Figure 3 by inserting the rubber packing 5 or the water-expandable rubber in the gap between the buried pipe assembly groove 30 and the buried pipe (2), the buried pipe assembly groove 30 and buried pipe ( 2) It is preferable to seal the gap between the buffer and to cushion the weight load or impact applied from the ready-made manhole (1).
