A plurality of elastic spacers are arranged between the outer body and the inner body to elastically support their relative positions, and compressed air is injected into the space between them through a pressure air supply to perform a shock absorption function. Furthermore, when an external impact is measured to be above a certain standard, the controller performs air injection, horizontal correction control of the cylinder, movement control of the wire-linked connection block, or overpressure relief control through an exhaust pump. In addition, a support portion and a lifting cylinder system are provided at the bottom of the outer body to automatically adjust horizontal imbalances caused by ground subsidence or tilting, and the outer periphery includes various fixing and shock-absorbing auxiliary structures such as embossed protrusions and radial elastic wing structures. The present invention provides an intelligent seismic structure that is clearly differentiated from existing fixed manhole structures by enabling a combined passive-active response to external impacts and simultaneously improving the horizontal stability, sealing reliability, ground adaptability, and durability of the structure.

Description

Technology Field

[0001] The present invention relates to a manhole structure installed embedded in a building structure, and more specifically, to an intelligent seismic-resistant building manhole structure designed to perform shock absorption and stabilization functions during external shocks, particularly earthquakes. Background Technology

[0003] In buildings, manholes serve as access passages and entry / exit routes for the maintenance and inspection of underground facilities. They are generally formed in a cylindrical or rectangular structure and are primarily manufactured from materials such as reinforced concrete (RC) or high-strength plastics (HDPE, PP).

[0004] Generally, a manhole is a main structure designed according to the depth of the burial site and the location of connecting pipes, and it comprises a body section to which water and sewage pipes, electrical conduits, communication conduits, etc., are connected, and a cover forming an upper opening. The cover is connected to the top of the body section so as to be openable and closable for access from the ground, and is formed of cast iron or composite material.

[0005] Construction manholes are structures buried underground that serve as connecting passages between underground facilities and the surface. They are exposed to continuous loads and environmental changes, and their structural stability and functional reliability can be severely affected, particularly by external impacts such as earthquakes. The major problems that may arise from such external impacts are as follows:

[0006] When the ground shakes or moves due to an earthquake, the manhole body is subjected to both horizontal and vertical forces simultaneously. In particular, traditional manholes made of concrete may develop cracks or, in severe cases, breakage. These cracks subsequently cause secondary problems such as groundwater inflow and contaminated water leakage.

[0007] Furthermore, manholes are located at connection points for water and sewage pipes, communication conduits, and power lines. Due to earthquakes, the joints between the conduit and the manhole body may widen or their fixing force may weaken, causing the connecting pipes to detach or break. This is a serious problem that can directly lead to the paralysis of urban functions.

[0008] Furthermore, as earthquake vibrations are directly transmitted to the surface, manhole covers may be lifted vertically or sink, potentially causing safety accidents on sidewalks or roads. This poses not only physical risks to vehicles and pedestrians but also issues such as falling debris entering the manholes.

[0009] Furthermore, if the ground subsides or loosens unevenly due to an earthquake, manhole structures may tilt to one side or, in severe cases, overturn. Particularly at points directly subjected to load, these issues significantly compromise the vertical stability of the structure.

[0010] Furthermore, if the slope or direction of drainage pipes is altered during an earthquake, normal water flow is obstructed, causing internal sewage to backflow or stagnate, which can lead to the overflow of groundwater and contaminated water. This can escalate into hygiene and environmental issues. Prior art literature

[0011] Republic of Korea Registered Patent No. 10-2705437 (Registration Date: September 5, 2024) The problem to be solved

[0012] This invention was devised to solve the aforementioned problems. Conventional construction manholes are primarily formed from reinforced concrete (RC) or synthetic resin and serve to facilitate the connection between buried facilities, such as water and sewage systems, telecommunications, and power lines, and the surface. However, in the event of natural disasters like earthquakes or external impacts, these existing manhole structures can experience various problems, such as damage to the structure itself, breakage of pipe connections, detachment or overturning of covers, or tilting due to ground subsidence. This causes serious issues that impede the normal functioning of urban infrastructure and can even lead to safety accidents.

[0013] In particular, because existing manhole structures have no or extremely limited active response capabilities to external impacts, they must rely on passive and delayed repair measures after structural damage occurs, which has resulted in delays in repair time and increased costs.

[0014] Furthermore, in the event of slight tilting or eccentricity caused by external impact, existing manholes lack the means to restore or maintain a horizontal state, which can lead to deformation or functional degradation of the equipment over the long term; additionally, in structures where multiple connecting pipes are inserted, separation or detachment of the connections may occur, resulting in limitations in maintaining durability and airtightness.

[0015] Accordingly, the present invention aims to provide an intelligent seismic-resistant manhole structure for construction that, in the event of external impact, particularly vibration or ground displacement caused by an earthquake, secures shock absorption and mitigation functions by forming the internal structure of the manhole body with a plurality of elastic support structures and pressure air injection structures; detects the intensity of the external impact and the horizontality of the structure in real time using impact sensors and horizontal sensors; stabilizes the manhole structure through air filling and control of the expansion cylinder operation when a preset impact threshold value is exceeded; and, under certain conditions, allows the connection block inside the manhole to be moved via wire drive to distribute the load on the connection part or actively respond to structural deformation, thereby maintaining stable function even under external impact, dramatically improving the seismic performance of the structure, and simultaneously solving existing problems of structural vulnerability and delayed recovery. means of solving the problem

[0037] A ring member is installed in each of the above pair of connecting pipes, and

[0038] Each of the above ring members is exposed in the above interspace, and

[0039] On the inner circumference of the outer body around the aforementioned pair of first connecting holes,

[0040] Each cylinder having an extendable shaft is installed, and

[0041] The above cylinder is connected to the inner circumference of the outer body through a spherical first ball member, and

[0042] The above shaft is connected to the circumference of the ring member through a spherical second ball member, and

[0043] Each of the above ring members is equipped with a horizontal sensor that measures the horizontal level and transmits the measured horizontal level to the controller.

[0044] The above controller controls the extension and retraction of the shafts of each of the above cylinders,

[0045] If the measured external impact force is less than the reference impact force corresponding to a preset earthquake occurrence, the axis of the cylinder is extended or retracted to achieve the measured horizontal level, and

[0046] The method is characterized by stopping the extension and retraction movement of the shaft of the cylinder when the measured external impact force exceeds the reference impact force corresponding to a preset earthquake occurrence.

[0047] In addition, each of the above-mentioned pair of first ball members is,

[0048] Each connecting block is installed to be rotatable, and

[0049] Inside the outer body around the aforementioned pair of first connecting holes,

[0050] A pair of winders is installed, and the pair of winders wind or unwind a wire, and

[0051] Each of the above connecting blocks is positioned in each of the waiting grooves formed on the inner circumference of the outer body, and

[0052] The wires of the above pair of winders are exposed through each of the above waiting grooves and connected to each of the above connection blocks,

[0053] If the above-measured external impact force exceeds the above-measured reference impact force corresponding to a preset earthquake occurrence,

[0054] The above controller is characterized by driving the pair of winders to wind the wire to a set length.

[0055] In particular, a plate-shaped support having a certain thickness is installed in the ground so as to be located at the lower part of the manhole body.

[0056] The above support member is spaced a certain distance from the lower part of the above outer body.

[0057] The circumference of the above support is connected to the lower circumference of the above outer body through a corrugated tube.

[0058] At multiple upper positions of the above support member, lifting cylinders having lifting shafts that are raised are arranged.

[0075] The present invention enables shock absorption and mitigation during external impact through a double structure formed between an outer body and an inner body and pressurized air injected into the space between them. By having a shock sensor detect external force in real time and a controller drive an air supply unit, the entire structure has the effect of actively responding to the impact.

This has a highly advantageous effect for long-term structural maintenance.

[0078] In addition, when a set reference impact force or greater than that is detected, the connection block is controlled through a winder and wire mechanism, thereby enabling stress distribution or position adjustment of the manhole connection part, which has the effect of minimizing pipeline damage caused by earthquakes.

[0079] In addition, the present invention has the effect of enabling not only simple impact resistance but also flexible response to multi-directional displacement caused by ground vibration through a multi-functional structure such as a vacuum channel, wave-shaped inner and outer walls, and elastic spacers.

[0090] A manhole structure for construction having seismic resistance according to the present invention will be described below with reference to the attached drawings.

[0091] FIG. 1 is a drawing showing a manhole structure for construction having an earthquake-resistant function according to the present invention.

[0092] Referring to FIG. 1, a manhole structure for construction having an earthquake-resistant function according to the present invention comprises a manhole body (100) that is buried underground, has an internal space formed therein, has an opening formed at the top, and has a pair of connecting pipes (170) on both sides, and a cap part (200) that is coupled to the top of the manhole body (100) to seal the opening.

[0093] The above cap part (200) can be connected to the top of the manhole body part (100) by a screw.

[0094] The above manhole body part (100) includes an outer body (110), an inner body (120) disposed inside the outer body (110) so as to be spaced apart from the inner circumference of the outer body (110), a sealing member (130) that seals the space between the top of the outer body (110) and the top of the inner body (120), elastic spacers (140) that elastically connect and support multiple positions on the inner circumference of the outer body (110) and multiple positions on the outer circumference of the inner body (120), a pressure air supply device (150) that injects pressure air into the space between the inner body (120) and the outer body (110), an impact sensor (160) provided on the outer body (110) and measuring an external impact force, and a controller (800).

[0095] Each of the above elastic spacers (140) can have a structure in which one end is caught inside the outer body (110) and the other end is caught inside the inner body (120). Both ends of the above elastic spacers (140) form the shape of a catch projection (141).

[0096] In addition, one end and the other end of the above-mentioned sealing member (130) can also form a structure that is caught inside the outer body (110) and the inner body (120).

[0097] The above air supply unit (150) has an air supply line (151), and the air supply line (151) is connected to the space between. Air is supplied to the space between through the air supply line (151).

[0098] The controller (800) supplies pressure air to the interspace using the air supply unit (150) when the external impact force measured by the impact sensor (160) exceeds a reference impact force corresponding to a preset earthquake occurrence.

[0099] The building manhole structure having seismic resistance according to the present invention provides excellent shock mitigation and structural stabilization functions in the event of external shocks, particularly abnormal ground vibration situations such as earthquakes, through a double structure of an outer body (110) and an inner body (120) and an elastic connection method using an elastic spacer (140).

[0100] Specifically, the manhole body (100) is configured in a dual manner with an outer body (110) that directly receives external loads and an inner body (120) that forms a main flow path connecting pipe (170) and an internal space, and a plurality of elastic spacers (140) are elastically connected between the two bodies while maintaining a gap.

[0101] When an external impact is applied, these elastic spacers (140) cushion the impact and absorb relative displacement, thereby preventing direct stress concentration from occurring in the internal structure.

[0102] In particular, the locking projection (141) structure formed at both ends of each spacer (140) maintains connection stability between the outer body (110) and the inner body (120) and prevents the spacer (140) from detaching or becoming misaligned.

[0103] Additionally, a pressure air supply unit (150) capable of injecting compressed air is installed in the space formed between the outer body (110) and the inner body (120), and the operation is automatically driven by a controller (800).

[0104] Specifically, when an impact sensor (160) mounted on an outer body (110) detects an external impact force in real time and determines that the value is greater than a preset reference impact force (e.g., earthquake level), the controller (800) operates an air supply unit (150) to inject pressure air into the space between them.

[0105] This air injection is carried out through an air supply line (151) and acts as an immediate pressure balance and fluid damper inside the structure, thereby improving the dynamic stability of the entire structure and preventing excessive deformation. This is an active response method that could not be implemented in conventional fixed single-wall manhole structures.

[0106] In addition, the above-mentioned sealing member (130) seals the space between the top of the outer body (110) and the top of the inner body (120) to prevent pressure within the space from leaking out, thereby ensuring internal pressure maintenance performance and effectively preventing the inner body (120) itself from being deformed or damaged by impact when an impact occurs.

[0107] Since the above cap part (200) is fixed to the top of the manhole body part (100) by a screw connection method, it is designed so that the opening does not open even with vibration or impact, and stability and airtightness of the top of the structure are simultaneously ensured.

[0108] In conclusion, the present invention provides a seismic manhole structure equipped with a dual safety mechanism that passively absorbs shock when an external shock occurs, while simultaneously actively recognizing the shock and executing a structural response. This provides significant technical effects compared to existing technology in terms of preventing structural damage, adaptability to ground vibration, protection of internal components, and maintaining the stability of the connecting pipe (170).

[0110] FIG. 2 is a drawing showing an example in which a vacuum channel is formed inside an outer and inner body according to the present invention.

[0111] Referring to FIG. 2, the inner circumference of the outer body (110) and the inner circumference of the inner body (120) can form a wave-shaped surface.

[0112] Inside the outer body (110) and the inner body (120), a grid-shaped vacuum channel (170) is formed to maintain a set vacuum level.

[0113] The operation and effects of the present invention according to FIG. 2 are explained.

[0114] Referring to FIG. 2, the building manhole structure having seismic resistance according to the present invention forms a wave-shaped surface on the inner circumference of each of the outer body (110) and the inner body (120), and a grid-shaped vacuum channel (170) that maintains a set vacuum level is formed inside these bodies.

[0115] First, the inner surface of the wave shape is designed as a continuous curved surface or a wave-shaped geometric structure rather than a simple flat surface, providing a mechanical effect in which vibrations or shock loads transmitted from the outside are not concentrated on a specific surface but are dispersed and divided and absorbed.

[0116] In particular, wave structures have improved buckling resistance and deformation distribution capabilities compared to flat plate structures of the same thickness, enabling higher mechanical elasticity and stability against complex dynamic loads occurring from multiple directions, such as earthquakes.

[0117] Additionally, a grid-shaped vacuum channel (170) composed of a plurality of vertical and horizontal channels is formed within the structure of the outer body (110) and the inner body (120), and the channel is designed to maintain a vacuum state set as a closed space isolated from the outside.

[0118] This vacuum channel (170) serves to suppress resonance and dampen energy transfer when external shock or vibration energy is transmitted, without increasing the weight inside the structure, while being free of air or fluid.

[0119] In particular, by arranging multiple vacuum channels (170) in a grid shape, it is possible to uniformly distribute energy dispersion paths throughout the manhole structure regardless of the direction of load application, and at the same time provide multiple buffer paths that can relieve stress acting on the local structure.

[0120] The combination of such a wave inner surface and a grid vacuum channel provides a complex shock mitigation mechanism that disperses, absorbs, and blocks energy internally, rather than simply transmitting or reflecting impact loads externally, thereby ensuring significantly improved seismic performance and structural reliability compared to conventional single-layer planar manholes.

[0121] Consequently, the present invention provides a high-performance seismic manhole structure capable of realizing long-term structural stability and functional maintenance even when external dynamic loads such as earthquakes occur, by incorporating a physical energy damping structure into the design form of the outer body (110) and the inner body (120) itself, thereby improving shock dispersion and structural fastening strength without separate external reinforcement, and by integrating internal resonance suppression and energy dissipation technology using a vacuum channel (170).

[0123] FIG. 3 is a drawing showing the connection structure of a connecting pipe connected to a manhole body according to the present invention.

[0124] Referring to FIG. 3, a pair of first connecting holes (111) are formed in the outer body (110) at positions facing each other.

[0125] In each of the above pair of first connecting holes (111), each of the above pair of connecting tubes (170) is disposed.

[0126] In the inner body (120), a pair of second connecting holes (121) are formed at positions facing each other.

[0127] Each of the above pair of connecting pipes (170) is placed in each of the above pair of second connecting holes (121).

[0128] In each of the pair of first connecting holes (111) and each of the pair of second connecting holes (121), contact members (171) that are elastically attached to the circumference of each of the pair of connecting tubes (170) are installed.

[0129] A ring member (172) is installed in each of the above pair of connecting pipes (170).

[0130] Each of the above ring members (172) is exposed in the space between them.

[0131] In the inner circumference of the outer body (110) around the pair of first connecting holes (111) above, a cylinder (300) having an extendable shaft (310) is installed.

[0132] The above cylinder (300) is connected to the inner circumference of the outer body (110) through a spherical first ball member (311).

[0133] The above shaft (310) is connected to the ring member (172) through a spherical second ball member (312).

[0134] In each of the above ring members (172), a horizontal sensor (161) is installed to measure the horizontal level and transmit the measured horizontal level to the controller (800).

[0135] The above controller (800) controls the shaft (310) of each cylinder (300) to extend and retract.

[0136] The controller (800) extends and retracts the axis (310) of the cylinder (300) to achieve the measured horizontal level when the measured external impact force is less than the reference impact force corresponding to the preset earthquake occurrence.

[0137] The controller (800) stops the extension and retraction operation of the shaft (310) of the cylinder (300) when the measured external impact force exceeds the reference impact force corresponding to a preset earthquake occurrence.

[0138] The operation and effects of the present invention according to FIG. 3 are explained.

[0139] Referring to FIG. 3, the seismic-resistant manhole structure for construction according to the present invention is precisely configured in the connection structure of the connecting pipe (170) inserted between the outer body (110) and the inner body (120) so as to maintain the sealing and horizontal stability of the connection part even under vibration and impact conditions.

[0140] First, a pair of first connecting holes (111) are formed in the outer body (110) at positions facing each other, and a connecting tube (170) is inserted therein.

[0141] At the same time, a pair of second connecting holes (121) are formed at corresponding positions in the inner body (120), and a connecting tube (170) is inserted in the same way to penetrate the outer body (110) and the inner body (120).

[0142] At this time, an elastic sealing member (171) is installed around the circumference of the connecting pipe (170) to elastically seal the inner surface of the first connecting hole (111) and the second connecting hole (121) with the connecting pipe (170), thereby providing a function to prevent leakage due to vibration and to prevent separation or damage of the connecting pipe.

[0143] In particular, a ring member (172) is installed on the outer circumference of each connecting pipe (170), and this ring member is exposed in the space between the outer body (110) and the inner body (120). This ring member (172) functions as a movable connecting part capable of fine positional adjustment in response to external impact, and contributes to maintaining the positional stability and flexibility of the connecting pipe (170).

[0144] A spherical second ball member (312) is installed around the ring member (172), and this ball member is connected to an extendable shaft (310).

[0145] The shaft (310) is again connected to the cylinder (300) through the spherical first ball member (311), and the cylinder (300) is fixed to the inner circumference of the outer body (110). This multi-axis rotatable connection method allows the ring member to move freely without mechanical constraints even when the connecting pipe is tilted, positionally displaced, or vibration occurs, and prevents stress concentration at the connection point.

[0146] Additionally, a horizontal sensor (161) is installed on the ring member (172) to measure the horizontality of the ring in real time and transmit it to the controller (800). Based on the input horizontality information, the controller (800) finely controls the extension and retraction of the axis (310) of each cylinder (300) to maintain or restore the horizontal alignment state of the connecting pipe (170) and the internal structure of the manhole.

[0147] This horizontal correction operation allows the controller (800) to operate the cylinder (300) to perform an automatic horizontal adjustment function when the external impact is less than the reference impact force, and stops the operation of the cylinder when the external impact is determined to be greater than the reference impact force to prevent excessive operation in an unstable state. This has the effect of limiting unnecessary operation of the control system and preventing mechanical failure of the structure in the event of a large external force such as an earthquake.

[0148] As a result, the connection structure according to Fig. 3 combines multiple shock mitigation layers, flexible structural interoperability, and an intelligent horizontal correction algorithm to prevent various problems such as leakage, damage, separation, and horizontal deviation of the connection part that may occur due to external shock, and provides excellent effects in maintaining structural reliability and durability centered on the connection pipe.

[0150] Figure 4 is a drawing showing an example in which a winder is further provided on the outer body.

[0151] Referring to FIG. 4, each of the pair of first ball members (311) is rotatably installed on each of the connecting blocks (313).

[0152] A pair of winders (330) are installed inside the outer body (110) around the pair of first connecting holes (111), and the pair of winders (330) wind or unwind a wire (331).

[0153] Each of the above connecting blocks (330) is located in each of the waiting grooves (110a) formed in the inner circumference of the outer body (110).

[0154] The wire (331) of the pair of winders (330) is exposed through each of the respective waiting grooves (100a) and connected to each of the connecting blocks (313).

[0155] When the measured external impact force exceeds the reference impact force corresponding to a preset earthquake occurrence, the controller (800) drives the pair of winders (330) to wind the wire (331) to a set length.

[0156] The operation and effects of the present invention according to FIG. 4 are explained.

[0157] Referring to FIG. 4, the building manhole structure having seismic resistance according to the present invention includes a wire-based stress control structure connected to a winder (330) inside the outer body (110) to further improve the structural response capability against external impact.

[0158] Specifically, a pair of waiting grooves (110a) are formed on the inner circumference of the outer body (110), and a connecting block (313) is rotatably disposed in each of these waiting grooves (110a).

[0159] The above connecting block (313) is connected to the first ball member (311) and is also linked to the extension axis (310) of the cylinder (300). This structure provides mechanical flexibility that can flexibly relieve the connection of the structure when an external impact occurs.

[0160] Based on the waiting groove (110a), a pair of winders (330) are installed inside the outer body (110), and the winders (330) perform the operation of reeling or unreeling a wire (331). Each wire (331) is exposed to the outside through the waiting groove (110a) and connected to a corresponding connection block (313).

[0161] The above configuration operates by driving the winder (330) under the control of the controller (800) to unwind the wire (331) to a set length when an external impact is detected to be greater than a reference impact force.

[0162] The unwinding of the wire induces rotation and positional movement of the connecting block (313), thereby effectively dispersing the stress acting on the connecting part and preventing damage to the connecting pipe or breakage of the body due to excessive stress concentration.

[0163] In particular, this structure is designed to operate only when an impact exceeding a certain level occurs, so it is unaffected by everyday vibrations or minor external forces, while performing the function of actively controlling structural displacement or load only during high impacts.

[0164] In addition, unlike conventional simple fixed or mechanical buffering devices, the wire (331)-based control method can be used repeatedly in conjunction with a controller, and real-time restoration or subsequent recovery control is also possible. This allows for the provision of a continuous and adaptive seismic structure rather than a one-time buffering.

[0165] In conclusion, the configuration according to FIG. 4 maintains the mechanical stability of the connection part and provides an intelligent shock mitigation and stress distribution mechanism against external shocks by actively adjusting the position and rotational state of the connection block (313) through the winder (330) and wire (331) when an impact occurs. This is one of the key effects that enables the present invention to secure various technical advantages over existing technologies, such as multiple response, repetitive control, and ductile induction, as an earthquake-resistant structure.

[0167] Figure 5 is a drawing showing an example in which a support member is placed at the bottom of the manhole body.

[0168] Referring to FIG. 5, a plate-shaped support (400) having a certain thickness is installed in the ground so as to be located at the lower part of the manhole body (100).

[0169] The support member (400) is spaced a certain distance from the lower part of the outer body (110).

[0170] The circumference of the support member (400) is connected to the lower circumference of the outer body (110) through a corrugated tube (410).

[0171] At multiple upper positions of the support member (410), lifting cylinders (420) having lifting shafts (421) that are raised are arranged.

[0172] The upper end of the lifting shaft (421) of the lifting cylinders (420) is connected to multiple lower positions of the outer body (110) through a connector (422).

[0173] The above controller (800) raises the lifting shaft (421) of the lifting cylinders (420).

[0174] The outer body (110) is equipped with inclination sensors (810) that measure the inclination of the outer body (110) and transmit the measured inclination to the controller (800).

[0175] The controller (800) calculates the slope measured through the slope sensors (810) as an average slope and controls the lifting of the lifting axis (421) of the elevators (420) in real time so that the calculated average slope reaches a preset reference slope.

[0176] The operation and effects of the present invention according to FIG. 5 are explained.

[0177] Referring to FIG. 5, the building manhole structure having an earthquake-resistant function according to the present invention is equipped with a lower horizontal correction and support device including a support member (400) and a lifting cylinder system (420) so as to respond to ground subsidence or tilting phenomena caused by external impacts such as earthquakes.

[0178] First, a plate-shaped support member (400) having a certain thickness is installed in the ground to correspond to the lower part of the manhole body (100), and this support member (400) is positioned so as to be spaced a certain distance from the lower part of the outer body (110).

[0179] In this way, the support member (400), which is an independent foundation structure, acts as a separation layer for foundation vibrations and can block or delay the propagation of vibrations and subsidence between the external ground and the manhole body.

[0180] The circumference of the above support member (400) is connected to the lower end of the outer body (110) through a corrugated tube (410).

[0181] This corrugated pipe (410) is made of a flexible material so that even if minute deformation or vertical displacement of the ground occurs, it can cushion and dynamically absorb without causing direct stress concentration in the body (100).

[0182] Additionally, a plurality of lifting cylinders (420), each including a lifting shaft (421), are installed at multiple locations on the upper surface of the support member (400), and the lifting shaft (421) of each lifting cylinder (420) is connected to the lower end of the outer body (110) via a connecting member (422). Through this structure, an active height adjustment function can be provided to the lower support point of the outer body (110).

[0183] In particular, a plurality of tilt sensors (810) are installed on the outer body (110), and these sensors precisely measure the tilted state of the outer body and transmit the information to the controller (800).

[0184] The controller (800) calculates the real-time average slope based on slope information received from multiple sensors, and if the average slope exceeds or falls short of a preset reference slope, it drives the lifting cylinder (420) to independently control each lifting axis (421) up and down, thereby automatically restoring or maintaining the horizontal state of the external body.

[0185] This structure plays a decisive role in preventing the detachment, damage, or displacement of the internal connecting pipe (170) and ensuring the functional continuity of the internal equipment of the manhole by actively correcting the lower part of the structure to maintain the vertical stability of the entire manhole even when the ground subsides locally due to earthquakes or the structure is tilted at a certain angle.

[0186] As a result, the configuration according to Fig. 5 represents a step forward from conventional passive seismic design by implementing smart foundation control technology capable of detecting and controlling relative displacement between the ground and the structure in real time, thereby dramatically improving the ground responsiveness, long-term durability, and seismic correction capabilities of manhole structures for construction.

[0188] Figure 6 is a drawing showing an example in which embossed protrusions are provided on an outer body.

[0189] Referring to FIG. 6, embossed protrusions (115) are installed on the outer circumference of the outer body (110).

[0190] At multiple locations on the outer circumference of the above-mentioned outer body (110), second cylinders (116) having a second axis (116a) that extends are installed.

[0191] Each of the embossed protrusions (115) is installed on the second axis (116a) of the second cylinders (116).

[0192] The side circumference of each of the second cylinders (116) and the side protrusion of each of the embossed protrusions (115) are connected through a flexible elastic tube (117).

[0193] The operation and effects of the present invention according to FIG. 6 are explained.

[0194] Referring to FIG. 6, the construction manhole structure having an earthquake-resistant function according to the present invention provides a functional structure that simultaneously realizes external shock absorption capability as well as improved adhesion to the ground by providing an embossed protrusion (115) on the outer circumference of an outer body (110), a second cylinder (116) for active control thereof, and an elastic tube (117).

[0195] First, a plurality of embossed protrusions (115) are formed protruding at regular intervals on the outer surface of the outer body (110). These embossed protrusions (115) have the effect of creating a three-dimensional contact surface with the ground in response to external forces such as irregular earth pressure, lateral impact, and ground subsidence, and increasing the fixing resistance and friction coefficient of the entire structure. In other words, they allow the structure to be anchored more stably underground than on a smooth surface, and are effective in preventing the internal structure from separating due to external vibrations or horizontal forces.

[0196] In addition, the embossed protrusions (115) are not simple fixed structures, but are each connected to a second axis (116a) that is extendable, and the axis is controlled by a second cylinder (116). The second cylinder (116) is installed at multiple locations on the outer circumference of the outer body (110) so that the embossed protrusions (115) can be extended or retracted in the outward or inward direction as needed.

[0197] This active expansion structure enables shock absorption and maintenance of fixation stability by immediately adjusting the position of the embossed protrusions in response to displacement, tilting, or horizontal deformation acting on the external structure during an earthquake, thereby strengthening adhesion to the surrounding ground or dispersing stress.

[0198] In addition, a flexible elastic tube (117) is connected to the side of the second cylinder (116) and the side of the embossed protrusion (115) to absorb torsional force and lateral shear force generated during expansion and contraction, and to ensure durability and resilience due to the repeatability of mechanical operation. This plays an important role as a structural reinforcement element that suppresses fatigue failure or deformation accumulation that frequently occurs in mechanical connection parts.

[0199] In summary, this configuration according to Fig. 6 is a design that simultaneously satisfies the functions of securing frictional force with the ground, dispersing lateral stress, increasing structural fixing force, and preventing structural detachment, and is particularly effective in soft ground, impact-prone terrain, and slope-embedded environments.

[0200] As a result, the present invention organically links the embossed protrusion (115), the second cylinder (116), and the elastic tube (117) to realize an elastic outer wall structure capable of real-time adaptation to ground reaction, unlike conventional fixed manhole structures, thereby providing significant technical effects in terms of seismic performance, field application flexibility, and long-term stability.

[0202] FIG. 7 is a drawing showing an example in which an exhaust pipe is connected to a cap portion according to the present invention.

[0203] Referring to FIG. 7, the inner body (120) is equipped with a pressure sensor (820) that measures the pressure in the inner space and transmits the measured pressure to the controller (800).

[0204] An exhaust pipe (210) connecting the internal space and the outside is connected to the cap portion (200).

[0205] An exhaust pump (220) is installed in the exhaust pipe (210).

[0206] When the measured external impact force exceeds the reference external impact force and the measured pressure reaches a preset ideal pressure, the controller (800) uses the exhaust pump (220) to forcibly exhaust the pressure in the internal space to the outside through the exhaust pipe (210).

[0207] The operation and effects of the present invention according to FIG. 7 are explained.

[0208] Referring to FIG. 7, a manhole structure for construction having seismic resistance according to the present invention includes a pressure sensing and forced exhaust system so as to prevent structural damage or functional abnormalities caused by internal pressure by detecting and controlling the overpressure state of the internal space when an external impact occurs.

[0209] First, a pressure sensor (820) is installed in the inner body (120) to detect the pressure of the internal space in real time, and this sensor transmits the measured pressure data to the controller (800).

[0210] When external impacts, particularly vibrations such as earthquakes, are applied to the entire structure, a rapid increase in internal pressure in the relevant internal space may be induced by minute elastic vibrations of the outer walls and internal structure, pressure changes in the air injection system, etc.

[0211] Since such overpressure conditions can cause risks such as detachment of internal members of the structure, detachment of connections, loss of airtightness, and malfunction of internal equipment, the present invention is equipped with an active pressure exhaust means to prevent this.

[0212] Specifically, an exhaust pipe (210) is connected to the cap portion (200), and this exhaust pipe serves as a passageway connecting the internal space and the outside. An exhaust pump (220) is installed in the middle of the exhaust pipe (210) and is driven according to a control signal from a controller (800).

[0213] The controller (800) performs exhaust control based on the following dual conditions.

[0214] ① The external impact force must be greater than or equal to the standard impact force, ② The internal pressure must be greater than or equal to the preset ideal pressure.

[0215] When both of the above conditions are satisfied simultaneously, the controller (800) operates the exhaust pump (220) to forcibly discharge air from the internal space to the outside through the exhaust pipe (210).

[0216] In this case, forced exhaust prevents local expansion caused by increased internal pressure, failure of the connecting pipe seal, and amplification of internal vibrations, and plays a key role in restoring the airtightness and structural stability of the entire manhole structure.

[0217] In addition, this structure is not a simple passive exhaust system, but includes a closed-loop-based intelligent control system between the sensor, controller, and pump, thereby analyzing the presence or absence of external shock and the internal pressure status in real time and performing active responses appropriate to the situation.

[0218] In particular, when an earthquake occurs, the pressure in a sealed space can rise rapidly instantaneously as the air damper inside the structure operates. The present invention has the technical advantage of being able to predictively and preemptively resolve such abnormal pressure situations.

[0219] As a result, the configuration of the present invention according to FIG. 7 enables automatic exhaust control under overpressure conditions by integrating external impact force and internal pressure data, thereby realizing an intelligent pressure control mechanism that can dramatically improve the internal environmental stability, structural durability, and equipment protection of a manhole structure for construction.

[0221] Figure 8 is a drawing showing an example in which wing structures are further formed on an outer body.

[0222] Referring to FIG. 8, the outer circumference of the outer body (110) is further provided with a plurality of radially arranged elastic expandable wing structures (119).

[0223] The above wing structures (119) can absorb impact through deformation and restoration action against earth pressure and lateral ground impact.

[0224] Although not shown in the drawing, a spherical projection may be formed at the end of the wing structures (119), and pointed fixed projections may be further formed around each of the wing structures (119).

[0225] The operation and effects of the present invention according to FIG. 8 are explained.

[0226] Referring to FIG. 8, the construction manhole structure having seismic resistance according to the present invention additionally provides a plurality of radial elastic expandable wing structures (119) on the outer surface of the outer body (110), thereby implementing a structural elastic defense function that can actively respond to external impacts, particularly lateral ground pressure (earth pressure) and horizontal impact forces due to ground displacement.

[0227] The wing structures (119) are arranged radially around the outer circumference of the outer body (110) and are formed of an elastic material, so that when a load is applied from the outside, they are temporarily deformed and then restored to their original position after absorbing the shock.

[0228] This configuration enables the manhole structure to effectively absorb and disperse local lateral ground shocks caused by earthquakes, soil movement, or vibrations of surrounding structures, and improves structural stability by distributing loads concentrated on the entire outer body through multiple paths.

[0229] In particular, although not shown in the drawing, a spherical projection may be optionally formed at the end of the wing structure (119). This serves to increase the rotational resistance and ground stability of the structure by making the contact surface of the wing end with the ground a multi-point support point when rotating or sliding within the ground.

[0230] Additionally, a number of pointed fixing protrusions may be formed around each wing structure (119), and when inserted into the ground, they naturally form mechanical interlocking with the surrounding soil, thereby significantly reducing the risk of detachment, tilting, subsidence, etc., even when the outer body (110) shakes from side to side due to earthquakes, etc.

[0231] In summary, the elastic expandable wing structure (119) of the present invention provides multiple technical effects, such as mitigating lateral ground shock through restoring force after elastic deformation, increasing friction and fixing force through radial protrusions and pointed fixing structures, responding to external underground loads through a uniform radial pressure distribution structure, and improving vibration resistance and stability throughout the structure.

[0232] In conclusion, the application of the radial wing structure (119) according to FIG. 8 enables the active suppression of tilting, movement, detachment, and external damage of the structure even under various ground action conditions that may occur when the manhole structure is buried underground, and serves as a key element that substantially enhances the seismic performance and installation stability of the present invention.

[0233] The technical features of the present invention are explained above through the overall configuration.

[0234] The present invention comprises a double structure (110, 120) of an outer body and an inner body as a basic framework, and implements a mechanical cushioning function of absorbing relative displacement between structures and providing restoring force through a plurality of elastic spacers (140) installed between them. In addition, by injecting air into the spaced space through a pressure air supply (150), an active shock mitigation mechanism is combined that can immediately actively control the rigidity of the structures upon detection of an external shock.

[0235] Unlike existing technologies that attempt to respond to external forces through a simple single body or the passive placement of shock absorbers, the present invention is different in that it implements a dynamic seismic system that controls the mechanical response characteristics of the structure in real time through a passive-active composite control structure.

[0236] Additionally, a ring member (172) with a horizontal sensor (161) for measuring horizontality attached is installed around the connecting pipe (170), and this is linked to an external body through an extendable shaft (310) and a cylinder (300). The present invention provides a conditional active horizontal correction function that blocks unnecessary operation by automatically restoring horizontality when the external impact is below a reference value and stopping the extension of the shaft when the impact is above a reference value.

[0237] This connector-centered real-time position correction and control structure is not found in existing technologies, and is a novel technical configuration, particularly as a localized stabilization and horizontal control technology centered on the connectors rather than the entire structure.

[0238] In addition, the support member (400) and lifting cylinder (420) system installed at the bottom automatically raise and lower the support shaft (421) according to the inclination of the outer body (measured by the inclination sensor 810), thereby allowing the inclination between the foundation surface and the structure to be adjusted in real time. This significantly improves seismic reliability and ground adaptability by controlling the structure to actively maintain a horizontal position on the foundation surface, rather than controlling the entire upper part of the structure in response to ground subsidence or structural tilting caused by earthquakes, etc.

[0239] While existing manhole structures are fixed underground or only consider simple vertical support, the present invention provides a new technological effect of maintaining and restoring structural safety by incorporating an underground foundation control function.

[0240] In addition, if the pressure in the internal space rises abnormally, the pressure is automatically discharged to the outside through the exhaust pipe (210) and exhaust pump (220) linked to the pressure sensor (820), and this operation is performed only when the dual condition of external impact force + internal pressure is satisfied. This is not a simple exhaust system, but an intelligent back pressure relief system based on conditional operation logic, and is a core technology that prevents structural destruction in advance.

[0241] While simple airtightness or ventilation structures exist in existing technologies, there is no complex safety device that controls through the logical combination of pressure and shock conditions like this, and its high level of effectiveness is recognized.

[0242] Additionally, a number of ground contact and impact dispersion devices, such as embossed protrusions (115), radial elastic wings (119), and winder-based wire structures (331), are applied to the outer circumference of the outer body. Each of these adaptively responds or provides passive resistance depending on the direction, intensity, and position of the impact and the structure, and they work together to enable multidimensional dispersion of external impact and maintenance of fixation force.

[0243] This is a structure on a completely different level from the simple protrusions and reinforcing ribs of existing technology, forming an adaptive integrated control structure for ground responsiveness and structural motion.

[0244] Although the present invention has been described above with reference to the illustrated drawings, the present invention is not limited by the embodiments and drawings disclosed in this specification, and it is obvious that various modifications can be made by a person skilled in the art within the scope of the technical concept of the present invention. Furthermore, even if the effects of the configuration of the present invention were not explicitly described while explaining the embodiments of the present invention above, it is natural to acknowledge that the effects predictable by said configuration should also be recognized.
