Rapid shielding system {RAPID PROTECTION SYSTEM}

The present invention relates to a rapid shielding system and a control method thereof, and more particularly, to a rapid shielding system and a control method thereof for shielding an inflow of unexpected water into a tunnel due to leakage, submersion and explosion during construction and operation of a tunnel will be.

Our country is surrounded by sea on three sides, and there are geographical advantages by locating China to the east and China to the west. It is time to construct submarine facilities in order to take advantage of these advantages and to connect these countries and neighboring countries to develop as an economic center of world logistics and tourism. Currently, submarine tunnel related projects in Europe, Japan, .

However, there have been few studies on waterproofing related to tunnels in Korea, and there have been no studies related to submarine facilities.

In addition, in the construction of underwater facilities, high performance shielding system for control of inflow water in the tunnel when leakage water, leakage of water due to flooding and terror (explosion, etc.) occurs during construction and operation of submarine tunnels, The research is insufficient, and if such an accident occurs, the structural stability of the entire structure may be dangerous throughout the construction.

Especially, in case of submarine tunnels, there are difficulties in design and construction due to high pressure conditions and limitation of ground survey compared to general land tunnels. Underwater tunnels are difficult to construct due to leakage, immersion, especially terrorism When a sudden spring water is generated, a shielding facility is required to cope with a large amount of seawater flowing rapidly in the tunnel.

Accordingly, it is urgently required to develop a shielding facility for coping with sudden water and abnormal influent when constructing and operating a tunnel.

It is an object of the present invention to provide a rapid shielding system and a control method thereof that can effectively cope with sudden water and abnormal influent water when a tunnel is constructed and operated.

In particular, it is an object of the present invention to provide a rapid shielding system and its control method capable of actively controlling the degree of shielding of a tunnel according to the water level flowing into the tunnel and the level of the influent water.

It is another object of the present invention to provide a rapid shielding system and a control method thereof capable of rapidly shielding a tunnel and shortening a shielding time.

It is another object of the present invention to provide a rapid shielding system and a control method thereof that can improve the stability and reliability of a tunnel.

According to another aspect of the present invention, there is provided a rapid shielding system for selectively shielding an interior of a tunnel, comprising: a shielding portion selectively shieldable inside the tunnel; And a control unit for controlling the operation of the shield according to the result detected by the influent water sensing unit. The control unit controls the degree of shielding of the tunnel according to the level of the water flowing into the tunnel and the influent water, Can be actively controlled.

For reference, the tunnel in the present invention can be understood as a concept including both a terrestrial tunnel, a subterranean tunnel and a submarine tunnel, and the present invention is not limited or limited by the type and characteristics of the tunnel.

The shielding portion may be provided in various structures selectively shielding the inside of the tunnel, and the present invention is not limited or limited by the structure and characteristics of the shielding portion. In one example, the shielding portion may include an inflatable structure that is inflatably provided inside the tunnel, and a gas supply portion that supplies inflation gas for inflating the inflating structure.

The inflatable structure may optionally be provided with a constricted and pivotable structure, and the present invention is not limited or limited by the structure and characteristics of the inflatable structure. Preferably, the shielding portion may include a first inflating structure for shielding a portion inside the tunnel, and a second inflating structure for shielding another portion inside the tunnel. In some cases, the shielding portion may be constituted by a single inflating structure or may include three or more inflating structures.

Further, since the inflating structure can be disposed in a state of being contracted (non-inflated state) at normal times (when no inflow water is generated in the inside of the tunnel), the inflating structure can be disposed in a non-expansion state of the inflating structure, A supporting member for temporarily supporting the light emitting diode on the light emitting diode may be provided. The support member may be provided in various structures that can temporarily support the unexpanded state of the expansion structure, and the present invention is not limited or limited by the type and structure of the support member.

The influent sensing unit may be configured to sense inflow water flowing into the tunnel in various ways depending on the required conditions and design specifications. For example, the influent water sensing unit may be configured to sense the influent water by sensing the level of the influent water flowing into the tunnel. In some cases, the influent water sensing unit senses the influent water flowing into the tunnel by sensing the flow rate or the flow rate of the influent water.

In addition, the influent water sensing unit may include a plurality of water level sensors for sensing different water levels within the tunnel. For example, the influent water sensing unit may include a first water level sensor for sensing a first water level of inflow water flowing into a tunnel, a second water level sensor for sensing a second water level relatively higher than the first water level, And a third water level sensor for sensing a high third water level.

The first level sensor to the third level sensor may be mounted at various positions capable of sensing different levels of water level. For example, the first level sensor to the third level sensor may be mounted at different heights at the same point and configured to detect different levels. In some cases, the first water level sensor to the third water level sensor may be mounted at different points having different tunnel depths (or tunnel slopes) to detect different water levels.

The control unit is configured to control the operation of the shielding unit according to the result detected by the influent water sensing unit. For example, the control unit may be configured to adjust the degree of expansion of the expansion structure according to a result sensed by the influent water sensing unit. For reference, in the present invention, it is understood that the control unit adjusts the degree of expansion of the expansion structure by adjusting the parameters related to the expansion timing, the expansion rate, and the expansion of the expansion structure.

Preferably, the control unit may be configured to control the operation of the shielding unit step by step according to the result detected by the plurality of water level detection sensors. For example, the control unit may perform an expansion preparation step of preparing the expansion structure for expansion when the water level is sensed by the first level sensor, and when the water level is sensed by the second water level sensor, And when the water level is sensed by the third water level sensor, the expansion maintaining step of maintaining the expansion state of the expansion structure can be performed.

The expansion preparation steps can be defined in various ways depending on the required conditions and design specifications. For example, in the expansion preparation step, the expansion structure may be in a state immediately before expansion. For example, in the preparation for expansion, the support structure of the inflatable structure by the support member can be released, and the inflatable structure can be deployed in an expanded form so that the inflatable structure can be easily expanded as the support structure of the inflatable structure is released . In some cases, it is possible to maintain the support state by the support member in the expansion preparing step, and to wait in a state immediately before the gas supplying section can supply the inflation gas. Alternatively, it is also possible to arrange that the support structure is released by the support member in the expansion preparing step, and that the inflating structure starts to expand at a slower rate than the inflation advancing step to be described later.

In addition, when the water level is sensed by the first water level sensor, the inflow water introduced into the tunnel may be drained to the outside of the tunnel using a drainage unit, and an alarm generator may be provided to generate an alarm signal when the water level is sensed by the first water level sensor can do. Here, the alarm signal may include at least one of an audible alarm signal by a normal acoustic means and a visual alarm signal by a normal warning light. In addition, a tunnel passenger and an operator may be informed of the occurrence of an abnormal influent water Other various alarm signals may be used.

According to another preferred embodiment of the present invention, there is provided a control method of a rapid-blocking system including a shielding portion selectively shieldable inside a tunnel and an influent water sensing portion for sensing inflow water flowing into the tunnel, An influent water sensing step of sensing influent water flowing into the inside of the housing; and a shielding step of controlling the operation of the shielding part in accordance with the result detected in the influent water sensing step.

In the influent detection stage, inflow water flowing into the tunnel can be detected in various ways according to the required conditions and design specifications. For example, in the influent water sensing step, the influent water can be detected by sensing the level of the influent water flowing into the tunnel. In some cases, it is possible to detect the inflow water flow rate or the flow rate in the inflow water sensing step or to detect the inflow water flowing into the tunnel in other ways.

For example, the influent water sensing step may include a first water level sensing step for sensing a first water level in the tunnel, a second water level sensing step for sensing a second water level higher than the first water level in the tunnel, And a third water level sensing step of sensing a third water level higher than the first water level. In some cases, it is also possible that the influent water sensing step excludes the first water level sensing step and includes only the second water level sensing step and the third water level sensing step. Alternatively, it is also possible that the influent detection step comprises four or more steps.

For reference, the shield can be provided in a variety of structures that can selectively shield the tunnels according to the required conditions and design specifications. In one example, the shielding portion may include an inflatable structure that is inflatably provided inside the tunnel, and a gas supplying portion that supplies inflation gas for inflating the inflating structure. Preferably, the shielding portion may include a plurality of expansion structures that cooperatively shield the inside of the tunnel. In the shielding portion control step, the degree of expansion of the plurality of expansion structures may be controlled together. Here, the first expansion structure and the second expansion structure are controlled together. The first expansion structure and the second expansion structure are simultaneously expanded under the same conditions, and the first expansion structure and the second expansion structure have a time difference And can be understood as a concept that includes both states that are sequentially expanded under different conditions.

In the shielding portion control step, the degree of expansion of the inflating structure may be adjusted according to the result detected in the influent water sensing step. Here, adjusting the expansion degree of the expansion structure can be understood as adjusting the parameters related to the expansion time, expansion rate and expansion of the expansion structure. For example, in the shielding portion control step, an expansion preparation step of preparing the expansion structure for expansion when the first water level is sensed in the first water level sensing step, and an expansion preparation step for expanding the expansion structure when the second water level is sensed in the second water level sensing step And an expansion maintaining step of maintaining the expansion state of the expansion structure when the third water level is sensed in the third water level sensing step.

In addition, when the inflow water is detected in the inflow water sensing step, the inflow water introduced into the tunnel may be discharged to the outside of the tunnel. It is also possible to include an alarm generating step of generating an alarm signal when an inflow water is detected in the tunnel at the inflow water sensing step.

As described above, according to the present invention, it is possible to effectively cope with sudden water and abnormal influent water when the tunnel is constructed and operated.

Particularly, according to the present invention, the degree of shielding of the tunnel can be actively controlled according to the water level of the water flowing into the tunnel and the inflow water. Therefore, it is possible to effectively prevent large-scale human and material damage caused by unexpected accidents such as water in the tunnel.

In addition, according to the present invention, when the water level, which is substantially not required to be shielded, is detected, the inflating structure maintains the inflation ready state. When the water level required for shielding is sensed, the inflating structure can be immediately inflated, The shielding time can be shortened.

Further, according to the present invention, since the tunnel can be shielded by using a plurality of inflatable structures, the shielding time can be further shortened and the shielding efficiency can be improved.

Further, according to the present invention, flooding of the tunnel can be prevented, and stability and reliability of the tunnel can be improved.

7 is a block diagram for explaining a method of controlling the rapid shielding system according to the present invention, and FIG. 8 is a method for controlling the rapid shielding system according to the present invention, in which the influent water sensing step and the shielding part 200 control step Fig. In addition, the same or equivalent portions as those in the above-described configuration are denoted by the same or equivalent reference numerals, and a detailed description thereof will be omitted.

Referring to FIG. 7, there is shown a control system of a rapid shielding system including a shielding part 200 selectively shielded inside a tunnel 10 and an influent water sensing part for sensing inflow water flowing into the tunnel 10 The method includes the steps of sensing influent water flowing into the tunnel 10 and controlling the operation of the shielding unit 200 according to a result detected in the influent water sensing step Step S20.

Step 1 :

First, the inflow water flowing into the tunnel 10 is sensed (S10)

In the inflow water sensing step S10, inflow water flowing into the tunnel 10 can be sensed in various ways according to required conditions and design specifications. For example, in the influent water sensing step S10, the inflow water can be sensed by sensing the water level of the inflow water flowing into the tunnel 10. In some cases, it is possible to detect the inflow water flow rate or the flow rate in the inflow water sensing step or to detect the inflow water flowing into the tunnel in other ways.

For example, the influent water sensing step S10 may include a first level sensing step S12 for sensing a first level within the tunnel 10 and a second level sensing step S12 for sensing a second level higher than the first level in the tunnel 10 A second water level sensing step S14 and a third water level sensing step S16 sensing a third water level higher than the second water level in the tunnel 10. In some cases, it is also possible that the influent water sensing step excludes the first water level sensing step and includes only the second water level sensing step and the third water level sensing step. Alternatively, it is also possible that the influent detection step comprises four or more steps.

Step 2:

Next, the operation of the shielding unit 200 is controlled according to the result detected in the influent water sensing step (S20)

For reference, the shield 200 may be provided with various structures capable of selectively shielding the tunnel 10 according to required conditions and design specifications. In one example, the shield 200 may include an inflatable structure that is inflatably provided within the tunnel 10, and a gas supply unit that supplies inflation gas for inflating the inflatable structure. Preferably, the shield 200 may include a plurality of expansion structures that cooperatively shield the inside of the tunnel 10. In the control of the shield 200, the degree of expansion of the plurality of expansion structures may be controlled together . The first inflator structure 212 and the second inflator structure 222 are controlled together so that the first inflator structure 212 and the second inflator structure 222 are simultaneously operated under the same conditions (for example, Gas supply condition), and a state in which the first expansion structure 212 and the second expansion structure 222 are sequentially expanded in different conditions with a time difference.

For example, in the control step S20 of the shielding part 200, the degree of expansion of the expansion structure may be adjusted according to the result detected in the influent water sensing step. Here, adjusting the degree of expansion of the expansion structure may be understood to control parameters related to the expansion time, expansion rate, and expansion of the expansion structure.

Preferably, the degree of expansion of the expansion structure may be controlled stepwise according to the result (depending on the level of the inflow water) sensed in the plurality of water level sensing steps in the control step S20 of the shielding part 200. [ For example, in the control step S20 of the shielding part 200, an expansion preparation step S22 for preparing the expansion structure for expansion when the first water level is sensed in the first water level sensing step S12, An expansion progressing step (S24) of expanding the inflating structure when the second water level is sensed in the sensing step (S14); and an inflation advancing step of inflating the inflating structure when the third water level is sensed in the third water level sensing step (S16) And the maintenance step S26 may be performed.

In the expansion preparation step (S22), the expansion structure may be in a state immediately before expansion. For example, in the preparation for expansion, the support structure (see 216 and 226 in FIG. 2) may be released from the support structure, and as the support structure of the support structure 216 and 226 releases the support structure, As shown in FIG. In some cases, it is possible to maintain the support state by the support member in the expansion preparing step, and to wait in a state immediately before the gas supplying section can supply the inflation gas. Alternatively, it is also possible to arrange that the support structure is released by the support member in the expansion preparing step, and that the inflating structure starts to expand at a slower rate than the inflation advancing step to be described later.

When the inflow water is sensed in the tunnel 10, the inflow water may be drained to the outside of the tunnel 10 when the inflow water is detected in the tunnel 10. It is also possible to include an alarm generating step of generating an alarm signal when the inflow water is detected in the tunnel 10 at the inflow water sensing step.

In the expansion progressing step (S24), the gas supply unit can supply the inflation gas to the maximum output so that the expansion structure can rapidly expand as quickly as possible.

In the expansion maintaining step S26, expansion of the expansion structure is completed and the expansion structure may have a structure corresponding to the cross-sectional shape of the tunnel 10, and the expansion structure may have a constant internal pressure .
