Description

Railway hybrid inspection route system and construction method of the same}

The present invention relates to a system and construction method for securing the width of the railroad bed that is insufficient for safely inspecting a railroad, reinforcing inclined slopes, and providing an efficient inspection path, and in particular, preventing inspectors from falling and ensuring safe walking inspection. It is about the railway hybrid inspection system and construction method that enables this.

Railway laws and regulations stipulate the width of the railway bed required for safe train operation. However, when constructed in the past, the railroad track standards did not meet the roadbed width required by current laws and regulations, so to secure the insufficient roadbed width, temporary measures were taken by installing sleepers on the side of the track or additional land was acquired to build stonework, retaining walls, etc. The width of the roadbed is being secured by installing a . However, the method of securing the width of the roadbed by installing sleepers on the side of the track is a temporary measure for a certain period of time, and the method of installing stonework and retaining walls after acquiring the land involves resolving civil complaints for acquiring the land and incurring excessive project costs.

In addition, the slope of the railway roadbed is relatively more vulnerable than other railway facilities to natural disasters such as heavy rain or earthquakes, so accidents involving slope loss or collapse frequently occur every year during the rainy season. In relation to this, reinforcement is being carried out on the slope of the track bed, but access to the reinforced area requires a separate construction access road during reinforcement, resulting in additional construction costs in addition to the reinforcement work, and many areas have been confirmed to be inaccessible other than the track due to topography and site conditions. It is becoming.

The technology behind the present invention includes Korean Patent Registration No. 10-2381955 (Patent Document 1), ‘Pile-type retaining wall structure for railway roadbed maintenance’ and Korean Patent Registration No. 10-2221710 (Patent Document 1). 2), ‘Slope reinforcement construction method and slope reinforcement structure using vegetation bags and perforated metal plates’. In the case of Patent Document 1, an earth retaining wall made of H-beams and concrete blocks was installed at the bottom of the railway roadbed to prevent slope loss and secure the construction base width. In particular, it has the advantage of not requiring unnecessary prior work such as temporary facilities following the installation of an existing retaining wall structure. In the case of Patent Document 2, it is durable enough to withstand collisions with driftwood floating from upstream to downstream, and the shape of the vegetation can be stably maintained even during fire or long-term exposure, making it possible to efficiently reinforce the slope of the revetment. It was allowed to happen. However, this background technology requires a separate access road for construction and excessive soil piling to secure the width of the roadbed, and when applied to places where on-site access is impossible, technical means using railroad tracks cannot be found.

Inspection of railroad facilities (track, roadbed, track structure, etc.) is necessary to maintain the safety and operational efficiency of railroad vehicles and includes frequent inspection, regular inspection, emergency inspection, and detailed diagnosis. For these various inspections and diagnosis, inspectors (workers) must have a safe walking path.

Since these inspections are generally performed while walking along a track, it is difficult to ensure safety. For example, a safety accident may occur due to tripping over a sleeper, and a safety space for evacuation cannot be secured when a railway vehicle is in operation, exposing one to the risk of an accident. Therefore, it is necessary to install an inspection structure that allows inspectors to inspect railroad facilities while ensuring a safe walking path.

Another technology that forms the background of the present invention is Korean Patent Registration No. 10-2417066 (Patent Document 3), which includes ‘Railroad Structure Safety Inspection Device’. This is to conduct safety inspections by installing an inspection frame and inspection assembly on the bogie moving along the rail. However, while this background technology has the advantage of inspecting damage and defects in railway structures such as tunnels, there is no technical means for inspection without using bogies and with a safe pedestrian passageway secured.

You can.

<Construction of basic piles>

Next, as shown in FIG. 8, the construction equipment 50 is operated to press-fit the foundation piles 20 into the roadbed slope 10a of the railway 10 at regular intervals. The foundation pile 20 may be constructed as a screw pile with one or more helical blades 202 installed on a steel pipe. Therefore, the foundation pile 20 is installed by rotary press-fitting, and a large bearing capacity can be obtained even if the press-fitting depth is small due to the tip bearing capacity of the helical blades 202.

<Installation of support anchor through inspection>

Next, as shown in FIG. 9, the support anchor 40 is installed as an inspection at the upper end of the foundation pile 20. The inspection road support anchor 40 is installed to stably support the inspection road structure 30 in a horizontal state. In addition, the inspection road support anchor 40 is installed to transmit the installation load of the inspection road structure 30 to the foundation pile 20 and share part of it.
