The present invention relates to a watch-type waterproof manhole buried in the road and a construction method for constructing the same, and more particularly, to provide a manhole structure to block inflow of inflow into the manhole, while leakage occurs to inflow external inflow into the manhole. If there is a problem, it will be detected early and the leak information will be prevented to prevent the inundation of expensive equipment in the manhole, and also to check the temperature, humidity, vibration, harmful gas, manhole cover open and open or abnormal power supply. This is to maintain the internal state of the manhole to the best.

In urban roads, many types of pipes are complexly buried in the ground and continuously buried, and underground spaces are installed in the elements to manage and control the pipes. In recent years, the need for more complex space for managing various electrical and electronic communication facilities required for industrial infrastructure construction has increased.

In the case of water supply and sewage pipes, they are not buried in the ground with only the connected continuous pipes, but each facility has additional facilities such as a water valve, air valve, pressure reducing valve, safety valve, Ito pipe, fire hydrant, etc. It is necessary to keep these facilities in one place for easy management or inspection. Therefore, according to their needs, manholes are installed on the ground, and space is created for people to enter the ground. The structure to create is a manhole.

The distillation valve installed inside the manhole body is used for the purpose of single watering and when the pipe change, leak, construction, pipe washing drainage, branching of water supply pipe, and the like is necessary for single watering, and to promote drainage and smoothly move the fluid. To adjust the water pressure.

Because of this need, manholes are installed underground to install valves and operate the valves to control pipelines. Manhole construction in the ground has been used masonry construction method for a long time, as shown in Figures 1 to 3 to change the space and shape of the manhole according to the diameter of the pipeline, such as luster pressure, earth pressure and fluid load flowing through the pipeline Considering the configuration of the manhole (1).

1 is an underground cross-sectional view of a manhole 1 constructed around a valve 3 installed in a pipe 2 having a relatively small hole. 2 shows the manhole 1 with the position of the valve 3 biased to one side and a relatively large hole in the tube 2. 3 is an underground cross-sectional view of the manhole 1 installed in the tube 2 of the larger hole.

The manhole (1) by the masonry construction method can be divided into the main parts as follows regardless of the space and shape.

Valve (3) installed in pipe (2) and pipe (2), floor concrete (4) laid on the excavated floor surface at a slight distance from pipe (2), pedestal (5) under the valve (3) ) Is installed and the brick (6) or frame (7) to secure the upper and lower space of the pipe (2) to form the manhole (1), the supplementary concrete (8) is installed at the position to be the upper surface of the manhole (1) or Pole 9, a tow 10 provided in the entrance hole of the manhole 1, a manhole cover 11, and the like.

The manhole (1) by the masonry construction method requires supplementary work such as watertight construction for watertightness and leakage measures against water pooling, and since the masonry construction method itself requires a lot of time, there is a problem of delay of air. In the case of urban roads, all construction is related to traffic communication, which is not suitable for construction conditions that require shortening of air.

Manhole construction methods and structures thereof are known to improve the manhole construction problems by the masonry construction method.

4 is a structure for replacing the problem of the masonry construction manhole, the manhole construction method using the same, the underground space for securing the valve operation space by excavating the road or ground around the installation position of the valve (12) ) The process of forming, the foundation of the base layer to form the bottom surface of the underground space (12) and lay the block 26 on the upper surface of the base layer 12 as a block layer, across the underground space (12) A valve 3 is installed in the pipe 2, and the lower frame 22, which forms a lower portion of the valve chamber 1 along the pipe 2 in both directions about the valve 3, is installed in the underground space 12. In the process of constructing the lower part of the valve chamber 1 by putting it in contact with the block layer, the upper frame 23 corresponding to the lower frame 22 of the valve chamber 1 is introduced into the basement space 12 so that the lower frame ( 22) The process of constructing the upper part of the valve chamber (1) centering on the valve (3), the upper frame 23 and the lower part put into a predetermined position Assembling (22) along the pipe (2) and inserting the sealing member between the corresponding contact surface and the upper and lower frame (22) 23 assembly process, install the iron 10 in the upper side of the valve chamber (1) Since the periphery is to be constructed by installing a protection structure, it is possible to eliminate various problems caused by building bricks and to shorten the air to some extent, but to block the inflow of inflow water flowing along the manhole cover 11. It was difficult.

As another form of the manhole, it is also known that the tube 2 passes through the manhole main body 30 so as to be manufactured more simply as shown in FIG. 5. The manhole body 30 has a corrugation portion that increases the stress on the horizontal earth pressure in the middle of the vertical wall surface, and has a cylindrical shape of an integral shape in which the reinforcing bars are erected at regular intervals along the wall circumference to reinforce the vertical wall surface. It is mainly made of round, square, etc., and made of light and cheap polyethylene resin among synthetic resins.

However, the man-made construction manholes of FIGS. 1 to 3 and manholes as shown in FIGS. 4 and 5 are known technologies that consider effective construction of underground manholes and modifications of manhole structures, and various electrical and electronic communications for various industrial infrastructures. There is a problem that facilities are difficult to manage systematically and integratedly. In other words, in recent years, the manhole has been installed with a combination of valves, including pipeline management, and facilities necessary for building an industrial infrastructure, but this cannot be satisfied.

This is an inevitable result of the fact that the manager installs the manhole to operate the valve to manage the pipeline and uses the manhole dedicated for the management of the valve pipeline. In order to construct various industrial infrastructures, wired / wireless communication equipment, repeaters, and various precision electric and electronic parts are required. These precision electric and electronic devices and parts are particularly vulnerable to leakage, humidity, dust, and gas.

Conventional manholes, which were able to control and control valves by installing manholes, did not have a system to systematically manage watertightness, proper humidity control, and vibration and gas exposure required for the construction of such an industrial infrastructure.

      Therefore, it is an object of the present invention to provide a supervised waterproof manhole that can comprehensively and systematically manage the interior of the manhole space to fit the interior space of the manhole to various installation conditions.

 Another object of the present invention is to manage the leakage of the interior space of the manhole, humidity, vibration, harmful gas, opening and closing of the manhole cover, power supply abnormality, etc., it is possible to install a variety of equipment required for the construction of industrial infrastructure To provide a surveillance waterproof manhole.

Another object of the present invention is to provide a construction method of the multi-purpose monitoring type waterproof manhole that can comprehensively and systematically manage the interior of the manhole space to match the interior space of the manhole to various installation conditions.

Manhole condition can be systematically managed systematically and comprehensively by transmitting and receiving information in real time by effectively utilizing public networks.

An example of the manhole leak detection will be described with reference to FIG. 10 as follows.

As shown in FIG. 9, the monitoring of leakage defects generated inside the manhole body measures current through insulation resistance generated between one pair of sensing lines (sensor) and two pairs of sensing lines (sensor) to measure the penetration of water and the degree of leakage. Detects the defect location by measuring the distribution voltage through resistance comparison measurement, which is suitable for the case where the detection area is formed in the longitudinal direction, and it is also applicable to the local area where the defect location is unnecessary. This is possible.

9A illustrates an example of a method of measuring insulation resistance, and the current Ip flowing through the insulation resistance Rp generated between the first sensor and the second sensor can be measured as follows.

Since the measured current (Ip) = Rs1 + Rp + Rs3 / Vcc

            Rs1 + Rp + Rs3 = Ip / Vcc.

 Since Rs1 >> Rp + Rs3, the insulation resistance value Rp = Vcc / Ip.

Vcc and Ip are known and measured values. The measured value can be found and defect information can be collected by comparing the degree of defect (leak / wetting) with the reference value.

9B is an example of a leak point measuring method, and the voltage Vp formed through the insulation resistance Rp due to a defect between the first sensor and the second sensor can be measured as follows.

Vp = Rs1 + Rs2 / Rs2 ＊ Vcc

The leakage point can be measured by the percentage of resistance with Vcc / Vp = Rs1 + Rs2 / Rs2 = Rs / Rs2 = L / L1 (Rs is the total resistance of the sensing line and L is the total length of the sensing line).

9 (a) and 9 (b) illustrate examples of measuring and detecting defects due to leakage and wet penetration in a manhole, and various known detection and measurement sensors can be utilized. Application is also possible.
