Description

[0001] The present application is a divisional application of the patent application No. 2021115337709, filed on December 15, 2021, entitled "Old wall protection and reinforcement method". TECHNICAL FIELD

[0002] The present application relates to the technical field of building protection and reinforcement repair, in particular to an old wall protection and reinforcement method, a wall protection and reinforcement system and a reinforcement construction method. BACKGROUND

[0003] China is a country with frequent earthquakes. With the strengthening of people's awareness of earthquake resistance and earthquake resistance, in earthquake-prone areas, modern buildings will consider the needs of shock absorption and protection when designing and building. However, for some old brick wall structures, such as gables of rural houses and decorative walls built in early time at some scenic spots, or even some old walls with cultural characteristics or special significance, their own strength is originally low, and with the passage of time, the strength further decreases and the brittleness increases, so it is easy to collapse. Especially under the action of earthquake, because the blocks of the wall rely entirely on their own bonding force to resist shear force, so it is easy to collapse in a broken way; the safety hidden danger is large.

[0004] Because some walls have certain special symbols or meanings, how to protect and reinforce such walls without rebuilding becomes a problem to be considered in the field, so as to better improve their collapse resistance and seismic resistance and improve the safety of the wall. SUMMARY

[0005] In view of the above technical problems of the prior art, the present application primarily solves the technical problem of providing a wall protection and reinforcement system and a reinforcement construction method that can improve the protection effect of the wall without rebuilding, and can be easily implemented on existing walls, greatly improving the protection effect of the wall, improving the seismic resistance and reducing the safety hidden danger.

[0006] In order to solve the above technical problems, the present application adopts the following technical solution:

[0007] An old wall protection and reinforcement method, characterized in that a cross beam of a concrete structure is uniformly and spacedly buried below the wall along the width direction along the length direction of the old wall, the middle part of the cross beam is fixedly connected to the old wall, and the two ends of the cross beam extend outward along the two sides of the old wall in the width direction and form a support for preventing tilting.

[0008] In this way, by adding a cross beam, the old wall can be well prevented from tilting and collapsing, and the protection and reinforcement effect is achieved.

[0009] Further, the damper is embedded on the beam below the two sides of the old wall, the surface of the old wall is reinforced and connected to the damper below, and the damper is relied on to transform and absorb the vibration to achieve the shock absorption and protection.

[0010] In this way, the wall surface is first reinforced to better prevent its fragmentation and collapse, and it is particularly suitable for use in the repair and reinforcement of old walls. At the same time, after the wall is reinforced as a whole and connected to the damper underground, the force of the wall swinging left and right can be transmitted to the damper below and absorbed and transformed, achieving the effect of shock absorption and protection, greatly improving the safety of the wall.

[0011] Further, the method is realized by relying on a wall protection and reinforcement system, which comprises a steel reinforced concrete beam arranged below the wall body, the two ends of the beam extending outward along the two sides of the wall body in the width direction of the wall body and forming a support for preventing the wall from tipping over, a wall reinforcement structure arranged on the wall body, and a damper symmetrically fixed and embedded on the beam below the ground on both sides of the wall, the lower end of the wall reinforcement structure being connected to the damper.

[0012] In this way, the beam can well prevent the old wall from tipping over and collapsing, and then the wall reinforcement structure is connected to the damper embedded in the beam at the lower end after the wall is reinforced, which can transmit the vibration to the damper to absorb and transform it when an earthquake occurs, achieving a good shock absorption and reinforcement effect.

[0013] Further, the beam has at least two beams arranged uniformly along the length direction of the wall.

[0014] In this way, the wall can be better prevented from tipping over.

[0015] Further, the lower side of the two ends of the beam has a support column extending outward and downward into the ground bottom.

[0016] In this way, the support strength of the beam against tipping over is better improved.

[0017] Further, the beam is integrally cast in place.

[0018] In this way, the beam is cast in place, which has less impact on the wall during construction, and the fixed connection between the beam and the wall can be conveniently completed by casting.

[0019] Further, the beam is embedded in the ground, leaving a certain gap between the upper surface of the beam and the lower end surface of the wall body, an upward connecting table is arranged on the central part of the upper surface of the beam opposite the central position of the wall body, and the wall body and the beam on both sides of the connecting table are filled with an elastic rubber material.

[0020] This is because the wall body itself is often low in strength (compared to old and brittle), so the structure is adopted, so that when the earthquake is small and the wall swings left and right, the swing amplitude is small, and the rigidity of the connecting table can be relied on to prevent the wall from swinging left and right, and the surface decoration is prevented from being damaged due to the swing of the wall. When the intensity of the earthquake increases, the connecting table position between the wall and the crossbeam can be disconnected (if the crossbeam is integrally connected with the wall, the wall is difficult to disconnect and is easy to collapse due to excessive swing), so that the wall can be disconnected and swing left and right; at the same time, due to the effect of the wall reinforcing structure, the strength and toughness of the wall are increased, and the wall will not be easily broken when it swings left and right and is disconnected from the crossbeam, and the wall will not be easily collapsed when it swings left and right and is constrained by the steel wire rope, and the swing force can be better transmitted to the damper below by the steel wire rope. The damper and the backfill soil between the longitudinal beam and the wall body realize shock absorption and conversion of energy, and the elastic rubber material filled on both sides of the connecting table can also cooperate to realize shock absorption and energy dissipation, so that the wall can be better prevented from collapsing and breaking. In specific implementation, the connecting table at the upper end of the crossbeam is made of pure concrete and does not contain steel bars, which facilitates disconnection when the vibration is too large, and the specific area can be estimated according to the strength of the wall itself to better achieve the above effects.

[0021] Further, the wall reinforcing structure comprises a steel wire mesh arranged between the wall body and the surface layer on both sides of the wall body, and a steel wire rope vertically arranged on the steel wire mesh, the steel wire rope being downwardly connected to the wall in a reverse U-shaped structure, the steel wire rope being arranged corresponding to the damper and connected to the damper at the lower end.

[0022] In this way, the wall surface is reinforced by laying a steel wire mesh on both sides of the wall, and then the steel wire rope is downwardly connected to the damper, so that the wall and the crossbeam are not rigidly connected but have strong toughness, and the wall has a certain swing allowance. In this way, the steel wire rope is connected and reinforced on both sides of the wall through the steel wire mesh, but at the same time, the damper is retained to have a certain toughness, so that the vibration and swing of the wall during an earthquake can be well conducted downward to the damper of the crossbeam through the steel wire mesh and the steel wire rope, and the damper can absorb and convert the vibration, so as to realize vibration absorption and shock absorption. The part exceeding the absorption and conversion of the damper is supported and offset by the crossbeam. Therefore, while realizing shock absorption, the wall body can also be better prevented from being broken or collapsed due to insufficient material strength, the seismic toughness is improved, and the shock absorption and protection effect of the wall is better improved. The present scheme is particularly suitable for protection upgrade and reconstruction of old walls.

[0023] Further, the lower end of the steel wire rope is connected to the damper through a joint bearing.

[0024] In this way, the joint bearing is used to connect the steel wire rope and the damper, so that the lower end of the steel wire rope can have a larger swing range when the wall body shakes and swings, and the overall seismic toughness of the wall body is improved, and the wall body is prevented from collapsing due to insufficient strength of the wall body and hard pulling of the steel wire rope during an earthquake.

[0025] Further, steel pipe grooves are formed in the wall body on both sides of the damper in the vertical direction, and a steel pipe is arranged in the steel pipe groove, and the steel wire mesh has a concave profile at the position of the steel pipe groove and is crimped in the steel pipe groove by the steel pipe, and the steel wire rope is arranged in the steel pipe.

[0026] In this way, the steel pipe is arranged to better crimp the steel wire rope on the surface of the steel wire mesh and improve the reinforcing effect of the steel wire mesh on the wall body. More importantly, the steel pipe allows the steel wire rope to slide up and down in the steel pipe while retaining the pressure on the steel wire rope and the side of the wall body during left and right swinging of the wall body during an earthquake, thereby providing more swing room for the wall body and better toughness, and preventing the wall body from collapsing due to insufficient strength.

[0027] Further, a support structure is arranged between the position where the upper end of the steel wire rope passes over the top of the wall body and the wall body, the support structure comprising a support plate arranged on the upper surface of the wall body in the width direction, and an arc-shaped rope groove is further arranged on the upper surface of the support plate, and the steel wire rope is pulled and connected in the rope groove.

[0028] In this way, the steel wire rope can also have a certain sliding range to facilitate the release of more swing room for the wall body and better toughness during an earthquake.

[0029] Further, two wing plates extending outward from the width direction of the support plate are further arranged between the lower position of both ends of the support plate and the top of the wall body.

[0030] In this way, the top positions on both sides of the wall body can be better protected to prevent collapse due to stress concentration of the steel wire rope at this position.

[0031] Further, a decorative wall surface layer is arranged on the outer surface of the steel wire mesh to make it more beautiful and better combined with the wall body as a whole.

[0032] Further, the wall protection and reinforcement system is obtained on the basis of the existing old ground wall by the following reinforcement construction method, the reinforcement construction method comprises the following steps: a. measuring and mapping the ground wall to be reinforced to obtain its size data, and determining the number of cross beams to be constructed (the cross beams are usually arranged at an interval of about two meters, and the number can be increased or decreased according to the strength of the ground wall to be reinforced); b. excavating a cross beam pouring groove on site, the cross beam pouring groove penetrates through the ground wall along the transverse direction and extends beyond the ground wall by a distance of half a meter to one meter at both ends, support column holes with a length of half a meter to one meter are punched at the bottom of the groove at both ends, and support steel bars are embedded in the support column holes; c. pouring the cross beam in the cross beam pouring groove and forming a support column structure, the upper surface of the cross beam is 5-10 cm away from the ground (i.e. the lower end surface of the ground wall), and a damper is fixed and poured upward at a position opposite to the cross beam during the pouring process; the upper surface of the cross beam is formed into an upward connecting table at the center position by relying on the formwork, and is fixedly connected to the middle position of the lower end surface of the ground wall; after pouring, the elastic rubber material is filled between the connecting table and the ground wall, and the upper surface of the remaining cross beam is covered with backfill soil and is flush with the ground; d. when the surface of the ground wall has a decorative layer, the decorative layer on the surface of the ground wall is removed first, the wall body is exposed, a vertical steel pipe groove is excavated on the surface of the wall body at a position corresponding to the damper, a support plate is arranged on the upper surface of the wall body opposite to the upper end of the steel pipe groove, and wing plates are arranged under both ends of the support plate; e. the steel wire mesh is laid on the surface of the wall body and is fixed by rivets, and the steel wire mesh is pressed into the steel pipe groove at the position of the steel pipe groove; f. the steel wire rope is lapped on the support plate, and after the both ends are threaded through the steel pipes, the lower end is pulled tightly and fixed to the damper, so that the steel pipe is pressed into the steel pipe groove and presses the steel wire mesh; g. repainting or laying a surface layer and / or a decorative layer.

[0033] Thus, the construction method can obtain the wall protection and reinforcement system, realizes reinforcement and protection of the existing wall, and enables better shock absorption. When the earthquake acts, the wall shakes, the steel wire rope is continuous, the whole wall is wrapped by the steel pipe and the steel wire mesh, the blocks are prevented from falling, and in addition, the steel wire rope pulls the whole wall to dissipate energy and reduce vibration through the damper embedded in the girder, prevents the wall from collapsing, when shaking, the steel wire rope overcomes the place of the top of the wall and the support structure will slide relatively, and the steel wire rope penetrates the position of the girder and will be inclined, therefore, the arc-shaped groove is arranged on the support structure, the joint bearing is arranged at the connection between the girder and the steel wire rope, so that the steel wire rope can freely move relative to the wall, and the wall is better pulled. The construction method itself has the advantages of convenience, quickness, high efficiency and reliability. The support and anti-tilting effect of the cross beam can be better improved, the old wall can have the double effects of preventing breakage by rigid shock absorption under small earthquake and preventing collapse by ductility shock absorption under large earthquake. The reinforcement construction of the wall can be conveniently, quickly and efficiently completed, and is extremely suitable for reinforcement, protection and anti-seismic treatment of the existing old wall. In addition, the method is more suitable for the old wall with relatively low strength, and for the old wall with higher strength, the longitudinal beam can be further arranged below the wall, the damper is arranged on the longitudinal beam, but the strength of the wall needs to be sufficient to bear the excavation of the longitudinal beam. The method is applied for another patent protection, and is not described in detail here.

[0034] In summary, the wall protection and reinforcement system can improve the protection effect of the wall without reconstruction, is easy to implement on the existing wall, can greatly improve the protection effect of the wall, improve the anti-seismic ability, and reduce the safety hidden danger.

[0038] The application will be further described in detail below in combination with specific embodiments.

[0039] EMBODIMENT

[0040] The application discloses an old wall protection and reinforcement method, which is characterized in that a concrete structure beam is uniformly and intervally buried along the width direction below the old wall along the length direction of the old wall, the beam is fixedly connected to the old wall above the middle part of the beam, and the beam extends outward along the two sides of the old wall in the width direction and forms a support for preventing the old wall from overturning.

[0041] In this way, the old wall can be prevented from overturning and collapsing by adding the beam, and the protection and reinforcement effect is achieved.

[0042] In the application, dampers are buried on the beams below the two sides of the old wall, the two sides of the old wall are reinforced and connected to the dampers below, the dampers are relied on to transform and absorb the vibration, and the shock absorption and protection are realized.

[0043] In this way, the surface of the wall is first reinforced, the wall is better prevented from breaking and collapsing, and the wall is particularly suitable for being used in the repair and reinforcement of the old wall. Meanwhile, the wall is connected to the dampers below after being overall reinforced, the left and right swinging force of the wall can be transmitted to the dampers below and absorbed and transformed in the case of earthquake, the shock absorption and protection effect is achieved, and the safety of the wall is greatly improved.

[0044] Specifically, the method is realized by a wall protection and reinforcement system as shown in the drawings. Figures 1-3 The wall protection and reinforcement system comprises a beam 2 made of reinforced concrete material and arranged below a wall body 1, the beam 2 extends outward along the two sides of the wall body in the width direction and forms a support for preventing the wall body from overturning, a wall reinforcement structure arranged on the wall body, and dampers 3 symmetrically and fixedly buried on the beams below the two sides of the wall, and the lower end of the wall reinforcement structure is connected to the dampers 3.

[0045] In this way, the beam can prevent the old wall from overturning and collapsing, the wall is reinforced by the wall reinforcement structure, and then connected to the dampers fixedly buried in the beam below, the vibration can be transmitted to the dampers and absorbed and transformed in the case of earthquake, and the shock absorption and protection reinforcement effect is achieved.

[0046] In the application, the beam 2 has at least two beams which are uniformly and intervally arranged along the length direction of the wall.

[0047] In this way, the wall can be better prevented from overturning.

[0048] In the application, the lower side of the two ends of the beam 2 has support columns 4 which extend outward and downward into the ground.

[0049] In this way, the support strength of the beam against overturning is better improved.

[0050] In the application, the beam 2 is integrally formed by cast-in-place.

[0051] In this way, the beam 2 is cast in place, which has less impact on the wall during construction, and the beam and the wall are fixedly connected by casting in place.

[0052] The beam 2 is embedded in the ground, leaving a certain gap between the upper surface of the beam and the lower end surface of the wall body. The upper surface of the beam is fixedly connected to the wall body through an upward connecting platform 5 arranged at the center of the wall body. The wall body and the beam on both sides of the connecting platform 5 are filled with an elastic rubber material 6.

[0053] This is because the wall body itself often has low strength (old and brittle). Therefore, when the earthquake is small and the wall swings left and right with small amplitude, the rigid connection and support of the beam connecting platform can directly prevent the wall from swinging left and right, and the surface decoration of the wall can be prevented from being damaged due to the swing of the wall. When the earthquake intensity increases and the wall swings, the connecting platform position between the wall and the beam can be disconnected (if the beam is integrally connected to the wall, the wall is difficult to disconnect and is easy to collapse due to excessive swing). The wall can be disconnected from the restraint and swing left and right; at the same time, due to the effect of the wall reinforcement structure, the strength and toughness of the wall increase, and the wall will not be easily broken when it swings left and right. The wall is restrained by the steel wire rope and will not easily collapse, and the swing force can be better transmitted to the damper below through the steel wire rope. The damper and the backfill soil between the longitudinal beam and the wall body can realize shock absorption and energy conversion. The elastic rubber material filled on both sides of the connecting platform can also cooperate to achieve the effect of shock absorption and energy dissipation. Therefore, the wall can be better prevented from collapsing and breaking. In specific implementation, the connecting platform at the upper end of the beam is made of pure concrete and does not contain steel bars, which can be easily disconnected when the vibration is too large. The specific area can be estimated according to the strength of the wall itself, so as to better achieve the above effects.

[0054] The wall reinforcement structure includes a steel wire mesh 7 arranged between the wall body and the surface layer on both sides of the wall body, and a steel wire rope 8 vertically arranged on the steel wire mesh 7. The steel wire rope 8 is in an inverted U-shaped structure with both ends pulled down and connected to the wall. The steel wire rope 8 is arranged corresponding to the damper and connected to the damper 3 at the lower end.

[0055] In this way, the wall surface is reinforced by laying steel wire mesh on both sides of the wall, and then the steel wire rope is pulled down and connected to the damper, so that the wall and the beam are not rigidly connected but have strong toughness, and the wall has a certain swing allowance. In this way, the steel wire rope is pulled and reinforced on both sides of the wall through the steel wire mesh, but at the same time, a certain toughness is reserved by relying on the damper, so that the vibration and swing of the wall during an earthquake can be well conducted downward to the damper of the beam through the steel wire mesh and the steel wire rope, and the damper absorbs and converts it, realizes vibration absorption and shock absorption, and the part exceeding the absorption and conversion of the damper is supported and offset by the beam. Therefore, while achieving shock absorption, it can also better avoid the wall body being broken or collapsed due to insufficient material strength of the wall body itself, improve the seismic toughness, and better improve the shock protection effect of the wall. The present scheme is particularly suitable for protection upgrading and reconstruction on old walls.

[0056] The lower end of the steel wire rope 8 is connected to the damper 3 through the joint bearing 9.

[0057] In this way, the joint bearing is used to connect the steel wire rope and the damper, so that the lower end of the steel wire rope can have a larger swing amplitude when the wall vibrates and swings, better improving the overall seismic toughness of the wall, and avoiding the wall collapsing due to insufficient strength of the wall itself during an earthquake. Improve the protection and shock absorption effect of the wall.

[0058] The steel pipe slot is provided with a steel pipe 10, the steel wire mesh 7 has an inner recessed profile at the position of the steel pipe slot and is crimped in the steel pipe slot by the steel pipe 10, and the steel wire rope 8 is arranged in the steel pipe 10.

[0059] In this way, the steel pipe is arranged to better crimp the steel wire rope on the surface of the steel wire mesh, improving the reinforcing effect of the steel wire mesh on the wall. More importantly, the steel pipe allows the steel wire rope to slide up and down in the steel pipe while retaining the pressure on the steel wire rope and the side of the wall during the left and right swing of the wall during an earthquake, thereby releasing more swing allowance for the wall and producing better toughness, avoiding the wall from being pulled and collapsed due to insufficient strength of the wall itself.

[0060] The upper end of the steel wire rope 8 is provided with a support structure between the position beyond the top of the wall body and the wall body, the support structure includes a support plate 11 arranged on the upper surface of the wall body in the width direction, and the upper surface of the support plate is further provided with a rope groove with an arc-shaped cross section, and the steel wire rope is pulled and connected in the rope groove.

[0061] In this way, the same is also for the convenience of the steel wire rope having a certain sliding allowance, so as to release more swing allowance for the wall and produce better toughness during an earthquake.

[0062] Two wing plates 12 extending outwards in the width direction of the support plate are arranged between the lower ends of the support plate 11 and the top of the wall body.

[0063] In this way, the top of the wall body on both sides can be better protected, and collapse caused by stress concentration of the steel wire rope can be avoided.

[0064] A decorative wall surface layer (not shown in the figure) is arranged on the outer surface of the steel mesh 7, so that the wall reinforcement structure can be better combined with the wall body as a whole.

[0065] The wall protection and reinforcement system is obtained by the following reinforcement construction method based on an existing old ground wall, and the reinforcement construction method comprises the following steps: a. measuring and mapping the ground wall to be reinforced to obtain its size data, and determining the number of cross beams to be constructed (the cross beams are usually arranged at intervals of about two meters, and the number can be increased or decreased according to the strength of the ground wall to be reinforced); b. excavating a cross beam pouring groove on site, the cross beam pouring groove penetrates through the ground wall on both sides in the transverse direction and extends beyond the ground wall by a distance of half a meter to one meter at both ends, support column holes with a length of half a meter to one meter are punched outwards and downwards at the bottom of the groove at both ends, and support steel bars are embedded in the support column holes; c. pouring the cross beam in the cross beam pouring groove to form a support column structure, the upper surface of the cross beam is 5-10 centimeters away from the ground (i.e. the lower end surface of the ground wall), and dampers are fixed and poured upwards at the positions corresponding to the cross beam in the lower position of the side surface of the ground wall during the pouring process; the upper surface of the cross beam is formed into a connecting table upwards in the center position by relying on the formwork during the pouring process, and the connecting table is fixed and connected to the middle position of the lower end surface of the ground wall; after pouring, the elastic rubber material is filled between the cross beam on both sides of the connecting table and the ground wall, and the upper surface of the remaining cross beam is covered with backfill soil and leveled with the ground; d. when the surface of the ground wall has a decorative layer, the decorative layer on the surface of the ground wall on both sides is removed first, the wall body is exposed, a vertical steel pipe groove is excavated on the surface of the ground wall on both sides at the position corresponding to the damper, a support plate is arranged on the upper surface of the wall body corresponding to the upper end of the steel pipe groove, and wing plates are arranged under both ends of the support plate; e. the steel mesh is laid on the surface of the wall body on both sides and fixed by rivets, and the steel mesh is pressed into the steel pipe groove at the position of the steel pipe groove; f. the steel wire rope is lapped onto the support plate, and the steel pipe is passed through the both ends and then pulled tightly and fixed to the damper, so that the steel pipe is pressed into the steel pipe groove and presses the steel mesh; g. the surface layer and / or decorative layer is repainted or laid.

[0066] Thus, the construction method can obtain the wall protection and reinforcement system, realizes reinforcement and protection of the existing wall, and better reduces vibration. When the earthquake acts, the wall shakes, the steel wire rope is continuous, the whole wall is wrapped by the steel pipe and the steel wire mesh, the blocks are prevented from falling, the whole wall is pulled by the steel wire rope to dissipate energy and reduce vibration through the damper embedded in the beam, the wall is prevented from collapsing, when the wall shakes, the steel wire rope is inclined at the position penetrating the beam, the arc-shaped groove is arranged on the support structure, the joint bearing is arranged at the connection position of the beam and the steel wire rope, the steel wire rope can freely move relative to the wall, and the wall is better pulled. The construction method has the advantages of convenience, high efficiency, reliability and the like. The support and anti-overturning effect of the beam are better improved, the old wall has the double effects of preventing the wall from being broken in small earthquakes and preventing the wall from collapsing in large earthquakes. The reinforcement construction of the wall is conveniently, quickly and efficiently completed, and the method is extremely suitable for reinforcement, protection and anti-seismic treatment of the existing old wall. In addition, the method is more suitable for the old wall with relatively low strength, for the old wall with higher strength, the longitudinal beam can be further arranged below the wall, the damper can be arranged on the longitudinal beam, but the strength of the wall needs to be enough to bear the excavation of the longitudinal beam. The method is applied for another patent protection, and is not described in detail.

When casting the crossbeam, the formwork is used to form an upward connecting platform at the center of its upper surface and fix it to the middle of the lower end of the ground wall. After casting, elastic rubber material is filled between the crossbeam on both sides of the connecting platform and the ground wall. The remaining upper surface of the crossbeam is covered with backfill soil and flush with the ground. When the surface of the ground wall has a decorative layer, first remove the decorative layer on both sides of the ground wall to expose the wall body. Then, cut vertical steel pipe grooves at the positions where dampers are set on both sides of the wall body. A support plate is set on the upper surface of the wall body directly opposite the upper end of the steel pipe groove. Wing plates are placed under both ends of the support plate. e. Lay the wire mesh on both sides of the wall body and fix it with rivets. The wire mesh is pressed into the steel pipe groove at the position of the steel pipe groove. f. The steel wire rope is attached to the support plate, and steel pipes are threaded through both ends. Then the lower end is tightened and fixed to the damper, so that the steel pipe is pressed into the steel pipe groove and presses down the steel wire mesh. g. Repaint or lay the surface layer and / or decorative layer.

7. A method for protecting and reinforcing old walls, characterized in that, Concrete beams are embedded at even intervals along the length of the old wall and along the width of the wall. The upper middle part of the beam is fixedly connected to the old wall, and the two ends of the beam extend outward along the width of the old wall to form a support that prevents overturning. Dampers are embedded in the horizontal beams below both sides of the old wall to reinforce the surface of both sides of the old wall and connect it to the dampers below. The dampers are used to convert and absorb vibrations to achieve shock reduction and protection. This method relies on the wall protection and reinforcement system as described in any one of claims 1-5; the wall protection and reinforcement system is obtained on the basis of existing old ground walls by relying on the reinforcement construction method as described in claim 6.
