Description

Structure of Concrete Transport Pipe Segment Connection for Ultra-High-Speed Mobility System Using Elastic Sealing Block and Connection Method

The present invention relates to a structure of a concrete transport pipe segment connection part for a high-speed transportation system, and more specifically, when a transport pipe segment for a high-speed transportation system such as a hyperloop is manufactured with concrete, the elastic restoring force It relates to a structure and a connection method of a concrete transport pipe segment connection for a high-speed moving system using an elastic sealing block, which maintains the sealed state of the transport pipe segment connection by the

In general, the ultra-high-speed tube train is a tube rail system that runs by making a closed space called a tube in a sub-vacuum state to overcome the speed limit of the existing maglev train. After wrapping the tube in a vacuum or sub-vacuum state, the air resistance is minimized to achieve greater speed with the same output. For example, an ultra-high-speed tube train can travel at a speed of 700 km per hour or more in a sub-vacuum state of, for example, 0.05 to 0.4 atmospheres, with a tube wrapped around the track.

Existing magnetic levitation trains have difficulties in increasing the speed of trains due to the limitations of air resistance and adhesive driving method, but the ultra-high-speed tube train system makes a tube structure and maintains a sub-vacuum state inside it to reduce air resistance, Non-adhesive driving using an electric motor enables high-speed operation of 700km/h or more.

This ultra-high-speed tube train system maintains the inside of the tube in a vacuum or sub-vacuum state, so a high aerodynamic design and precise control technology are required. For example, the diameter of the tube in the existing ultra-high-speed tube train can be about 4.5m to 10m. have. The vehicle of such a high-speed tube train system is a high-speed magnetic levitation train, and it is a structure that supports the vehicle and propels it with a linear electric motor while maintaining a certain distance with magnetic force on the guideway.

On the other hand, a high-speed transportation system such as Hyperloop, which is being recently developed, is a system in which a 3.2m-diameter tunnel created close to vacuum is created, and one 28-seater train runs inside. The maximum theoretical speed of this hyperloop high-speed movement system is 1223 km/h, which is twice that of a passenger plane, which is about 780 km/h. This high-speed mobility system is intended to solve problems such as population concentration, traffic congestion, traffic accidents, and the environment caused by urbanization. It can be said to be a sustainable means of transportation in the future.

Specifically, this hyperloop high-speed movement system is designed to attach a magnet to the lower part of the train, and to allow a magnetic field to flow through the tunnel floor. At this time, in order to reduce friction as much as possible, the train should run in a slightly floating state. To this end, the fan and compressor installed behind the train suck in the air remaining in the tunnel and blow it out to keep it in the air. In this way, for example, a train weighing 30 tons can be moved at a speed of more than 1200 km/h. In addition, in order to supply electricity necessary to generate a magnetic field, a solar panel may be installed on the outer wall of the vacuum tunnel, and a wind power generator may be installed around it. The construction cost of such a hyper-loop high-speed transportation system is only one-tenth of that of the high-speed rail, so fares can be lowered.

FIG. 1 is a diagram for explaining a hyperloop ultra-high speed mobile system, FIG. 2 is a diagram specifically illustrating a passenger vehicle in the hyperloop ultra-high speed mobile system shown in FIG. 1, and FIG. 3 is a hyperloop shown in FIG. It is a drawing that shows the transportation pipe in detail in the high-speed movement system.

As shown in FIG. 1 a), the hyperloop ultra-high-speed movement system installs a transport pipe between two stations, and uses a vacuum pump to increase the atmospheric pressure in the tube to a sub-vacuum state that is in the range of 1/1000 to 1/100 of atmospheric pressure. By minimizing air resistance, it is possible to run the inside of the transport pipe at a maximum speed of 1,200 km/h. At this time, the key is to block the inflow of air from the outside and secure sealing performance in order to maintain the atmospheric pressure inside the transport pipe to be within a certain range at a level close to vacuum.

The vehicle 10 of this hyper-loop high-speed mobile system, as shown in FIG. 2, looks like a train, but the actual operation method is much different from the existing train, and, in addition, is basically transported inside the transportation pipe 20 As a type of transportation means for moving the sieve 10, it is possible to obtain a driving force of the vehicle 10 by using a magnetic field inside the transportation pipe 20, and reduce frictional force by spraying air to the floor. Here, the required electric power can be obtained by a solar panel covering the outer wall of the transport pipe 20 . In addition, the vacuum tube type transport tube 20, as shown in FIG. 3, is manufactured by applying a steel pipe transport pipe to a hyperloop test line. Here, reference numeral 21 denotes a pier, reference numeral 22 denotes a support device, and reference numeral 24 denotes an expansion joint device, respectively.

On the other hand, Figure 4 is a view showing a tube structure for a high-speed tube railway according to the prior art.

As shown in FIG. 4, the tube structure for the high-speed tube railway according to the prior art is constructed such that a closed circular tube 20 surrounds the tracks 30a and 30b, respectively, and is constructed by continuously joining steel pipes. It allows a pod-shaped vehicle to travel at subsonic speed inside the tube with a circular cross section.

However, the tube structure for the high-speed tube railway according to the prior art is a steel tube transport pipe, and the cross section of a hollow circular tube (or transport pipe) has a relatively small secondary moment of cross section compared to an I-shaped or box-shaped section, so that bending behavior is difficult. It is an unfavorable shape for the bridge structure, which is the main type of behavior, and a separate connecting material should be provided to induce the synthesis between the circular steel pipe and the track structure.

In particular, when replacement of the tube (or transport pipe) is required, there is a problem in that the entire steel pipe and the track structure must be partially cut. In addition, in order to secure the flexural rigidity of the hollow circular cross-section vulnerable to flexure, a hoop-shaped reinforcing material must be provided, and the span must be shortened to secure flexural rigidity, so there is a problem in that the cost increases.

On the other hand, the most required performance of the sub-vacuum transport pipe for high-speed mobile systems is airtightness that can maintain 1/1000 atm. In the past, basic studies were mainly conducted on steel materials, and concrete transport pipes based on cement were manufactured. There is not one case yet.

In addition, concrete having general strength can secure watertightness like an immersed tunnel, but it is very difficult and uneconomical to secure airtightness in an environment such as 1/1000 atm. In order to secure this, it is difficult to secure the airtightness to maintain a single vacuum, and to secure this, a steel formwork with a thickness of about 10mm is required on the outside of the concrete to maintain a very thick covering thickness. Since there is no self-filling property, it is very difficult to manufacture it in a circular shape, and since it is difficult to secure airtightness due to poor concrete pouring in some sections, countermeasures are required.

In particular, the airtightness of the transport pipe segment itself is important because the sub-vacuum transport pipe of the high-speed transport system includes discontinuous sections such as construction joints and transport pipe segment connections. is known

In the case of such a concrete transport pipe, the air permeability of the concrete itself is inversely proportional to the strength, and the more joints there are, the higher the equivalent permeability of the structure. It was found that it takes about 4 to 5 hours to double to 20 kPa. This is a situation in which it is difficult to maintain a sub-vacuum inside using general concrete, so a material with better airtight performance is required. For example, ultra-high-performance concrete can be an alternative, but so far, ultra-high performance There is no sub-vacuum transport tube for ultra-high-speed transportation system using concrete (UHPC), and the ultra-high-speed transportation system using concrete vacuum tube has not been realized yet, only a concept is proposed or research is in progress.

On the other hand, FIG. 5 is a view showing that a transport pipe in the form of a bridge is constructed by connecting transport pipe segments according to the prior art, and FIG. 6 is a bending behavior by a transporter according to the prior art. This is a diagram showing what happens.

As shown in FIG. 5 , when the transport pipe according to the prior art is made of concrete, transport pipe segments 20a and 20b, which are unit members of a certain length, for example, about 7.5 m, are manufactured and connected thereto By doing so, it is possible to construct a bridge-type route structure with a span of about 25m.

At this time, the transport pipe segment connection part 23 is adhered with a filling material such as epoxy grout, and when the transport pipe bends, as shown by reference numeral A in FIG. 6 , the transport pipe segment connection part 23 spreads Displacement occurs and, accordingly, as the sealing structure in the transport pipe segment connection part 23 is broken, external air is introduced through the gap, and consequently, the inside of the transport pipe cannot maintain a vacuum state.

On the other hand, FIG. 7 is a view specifically illustrating a transport pipe segment connection method according to the prior art, in which a) of FIG. 7 shows an epoxy bonding method, b) of FIG. 7 shows a rubber ring method, and FIG. c) shows the blocking plate and grouting parallel method, respectively.

As a method of connecting the transport pipe segments according to the prior art, in addition to the method of grouting and bonding the transport pipe connection shown in FIG. 7 a), a method of sealing with the rubber ring (O-ring) shown in FIG. 7 b) , a method of paralleling the grouting and the blocking plate shown in FIG. 7 c) may be considered.

Specifically, in the case of the method of grouting bonding the transport pipe connection part shown in a) of FIG. 7, the bonding failure of the grouting connection part may occur during bending behavior, and even if the bending displacement is restored, there is a disadvantage that the fracture surface is not recovered. In addition, in the case of the sealing method with the rubber ring shown in b) of FIG. 7, the amount of displacement is small by applying a small diameter rubber ring, and a plurality of grooves for inserting the rubber ring must be prepared in advance when manufacturing the transport pipe. , in addition, there is a risk that the rubber ring is easily separated from the plurality of grooves. In addition, in the case of the method in which the grouting and the blocking plate are combined as shown in FIG. 7 c), the construction for the grouting is complicated, and there is a risk that the grouting and the blocking plate may be destroyed due to repeated bending behavior or excessive displacement. There is this.

In other words, according to the method of connecting the transport pipe segments according to the prior art, there is a disadvantage that the transport pipe cannot maintain airtightness if the width of the pipe is wide or if it is repeatedly displaced and destroyed. There is a need for a connection structure that can maintain a sealed state even with a large displacement and does not destroy the transport pipe connection even when opening and closing repeatedly act.
