Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a rapid motorized tunnel reinforcement and repair device and method. Background Art

[0002] Tunnel lining refers to a permanent structure that supports and maintains the long-term stability and durability of the tunnel. Its functions are: to support and maintain the stability of the tunnel, to keep the space required for train operation, to prevent weathering of the surrounding rock, and to relieve the impact of groundwater.

[0003] When a tunnel is damaged (especially during wartime) and is in danger, it is generally necessary to support the tunnel through a supporting structure to reinforce the tunnel wall and prevent the tunnel from collapsing. The supporting structure in the prior art mostly uses steel bars and steel plates to overlap into a frame, which is then connected to the top and side walls of the tunnel by anchoring, and then fixed by spraying and pouring concrete. The whole process is relatively complicated, requires a large number of workers to cooperate in the construction, and is time-consuming. Since the inside of the tunnel is damaged, the long installation time will greatly increase the danger. Moreover, since there are many accessories required and the construction location is high, it is necessary to cooperate with transfer equipment and climbing equipment for use, which is very inconvenient. In addition, during the anchoring process, the anchor rods need to be driven into the wall of the tunnel. The wall of the tunnel is prone to cracking, resulting in gravel and the surface of the wall falling, which can easily injure the workers in the tunnel, resulting in poor safety. In addition, the inner wall of the tunnel is often relatively moist, which makes it difficult for the concrete to solidify, and some missing areas require manual climbing, which is not convenient for quick filling.

[0004] In view of the above problems, the present invention proposes a rapid motorized tunnel reinforcement and repair device and method. Summary of the invention

[0053] The implementation of the present invention is described in detail below in conjunction with preferred embodiments.

[0054] See also Figure 1-6 A rapid motorized tunnel reinforcement and repair device 100 provided in an embodiment of the present invention mainly includes a tunnel reinforcement top support 101, a jacking assembly 102, a filling reinforcement assembly 103, a sealing chamber 104 and a stirring assembly 107.

[0055] Specifically, the top surface shape of the tunnel reinforcement top support 101 is consistent with the top wall shape of the tunnel 200 to be reinforced, so as to support and reinforce the tunnel 200 to be reinforced. The figure shows a common arc shape. The tunnel reinforcement top support 101 can adopt a light steel frame or truss structure to facilitate rapid motorized deployment. It can be transported and erected on site by a team of several people or with the help of small lifting machinery.

[0056] See also Figure 4The filling and reinforcing assembly 103 first includes a filling airbag 1033, which is arranged above the tunnel reinforcement top support 101 and has the same shape as the tunnel reinforcement top support 101. The filling airbag 1033 is used to form a hardened whole with the filling agent after being filled with the filling agent to support and reinforce the top wall of the emergency repair tunnel 200 to prevent the top wall from being partially broken, cracked, or cavitated. The filling airbag 1033 can be made of high-strength plastic, rubber, or polyurethane to prevent it from being easily punctured by gravel.

[0057] The filling reinforcement component 103 is also provided with a conveying pipe 1032, the top end of the conveying pipe 1032 is connected to the filling airbag 1033, and extends downward through the tunnel reinforcement top support 101, and the bottom end is connected to the stirring component 107, which will be explained in detail later. The conveying pipe 1032 is used to convey the filler mixed in the stirring component 107 to the filling airbag 1033.

[0058] There are two groups of jacking components 102, which are arranged oppositely on both sides of the tunnel to be reinforced and repaired, that is, on both sides of the tunnel cross section, and are arranged close to the side walls of the tunnel. The two groups of jacking components 102 jack up the tunnel reinforcement top supports 101 from both sides until they contact the top wall of the tunnel 200 to be reinforced and repaired.

[0059] There are two groups of sealed chambers 104, which are arranged opposite to each other on both sides of the tunnel to be reinforced and repaired, that is, on both sides of the tunnel cross section, close to the tunnel side walls. In this embodiment, the sealed chambers 104 are arranged on the inner side of the jacking assembly 102, and can be lifted synchronously with the lifting of the jacking assembly 102, and the sealed chambers 104 are used to fill fillers during reinforcement and repair.

[0060] There are also two groups of stirring components 107, which are arranged opposite to each other on both sides of the tunnel to be reinforced and repaired. In this embodiment, the stirring components 107 are arranged below the sealed chamber 104 to receive the filler in the sealed chamber 104. The upper part of the stirring components 107 is connected to the sealed chamber 104, and the lower part is connected to the bottom end of the conveying pipe 1032, so that the filler can be conveyed to the filling airbag 1033 via the conveying pipe 1032.

[0061] The rapid motorized tunnel reinforcement and repair device 100 of the present invention can make the tunnel reinforcement top support 101 contact the tunnel vault smoothly and quickly, so as to support the tunnel. This method can quickly realize the tunnel reinforcement and repair work, and there is no need to carry out anchor construction as in traditional reinforcement methods, thereby improving the construction progress, realizing rapid reinforcement and repair, and improving the safety of construction operations. This is especially necessary in occasions where rapid motorized reinforcement and repair are required, such as in wartime, to ensure that the road is opened quickly and smoothly.

[0062] By using a filling airbag 1033 above the tunnel reinforcement top support 101, after the filler is filled, the filler can accumulate in the hollow area, and the filling airbag 1033 will deform to fill the hollow, thereby maintaining uniform and full contact with the tunnel reinforcement top support 101, improving the reinforcement effect of the tunnel, and at the same time, it can also effectively reinforce the local broken and cracked areas of the tunnel, avoiding the problem of traditional reinforcement methods such as using wire mesh for only passive protection but not active reinforcement. Therefore, this method can quickly reinforce and repair, and can also avoid on-site personnel from working at heights.

[0063] Continue to see Figure 5 The embodiment of the present invention provides a specific lifting assembly 102, including: a fixing plate 1023, a scissor-type telescopic bracket 1024, and an electric telescopic rod 1021.

[0064] Specifically, there are two groups of fixed plates 1023, and the two groups of fixed plates 1023 are vertically opposed to each other, and the fixed plates 1023 are preset with a slide groove 1027, a telescopic frame fixing block 1025 is fixed at one end of the slide groove 1027, and a slider 1026 is arranged in the slide groove 1027, and the slider 1026 can slide in the slide groove 1027.

[0065] The scissors-type telescopic bracket 1024 is fixed between the upper and lower groups of fixed plates 1023, and its upper and lower ends are respectively connected to the two groups of fixed plates 1023, and one end of the scissors of the scissors-type telescopic bracket 1024 is hingedly fixed to the telescopic frame fixing block 1025, and the other end of the scissors is hingedly connected to the slider 1026. As the scissors-type telescopic bracket 1024 extends and contracts, the slider 1026 slides back and forth in the slide groove 1027.

[0066] At least one set of electric telescopic rods 1021 is installed on the scissor-type telescopic bracket 1024, for example, installed on one of the scissor units, and the two ends are respectively fixed to the two relative hinge nodes of the scissor unit of the scissor-type telescopic bracket 1024. By extending and retracting the electric telescopic rods 1021, the scissor-type telescopic bracket 1024 can be controlled to extend and retract, thereby realizing the lifting and lowering of the lifting assembly 102.

[0067] In the embodiment of the present invention, a base 1022 is arranged below each group of jacking components 102, and a group of fixing plates 1023 below are arranged on the base 1022. The base 1022 can be an integral structure with the base 1022 or a separate structure. During on-site reinforcement and repair, the base 1022 is supported on the tunnel floor, and the jacking components 102, the sealed chamber 104 and the stirring component 107 are arranged on the base 1022.

[0068] In the embodiment of the present invention, since the sealed chamber 104 is arranged on the inner side of the lifting assembly 102, the lifting assembly 102 further includes a connecting plate 1028, which is fixed to the side of a group of fixing plates 1023 above and extends inward, and is connected and fixed to the sealed chamber 104 by means of the connecting plate 1028, so as to achieve synchronous lifting of the sealed chamber 104. The connecting plate 1028 can be temporarily welded and fixed to the sealed chamber 104, but in order to reduce the difficulty of on-site layout and improve the motorization efficiency, the connecting plate 1028 can be fixed to the side and / or both ends of the sealed chamber 104 by means of a snap-on connection, for example, an intermittent or continuous strip-shaped card groove is preset on the side of the sealed chamber 104, and a buckle, a hook, a card strip and other structures are correspondingly extended from the side of the connecting plate 1028. Of course, other detachable connection methods are also feasible.

[0069] Continue to see Figure 6-7 The embodiment of the present invention provides a specific sealed chamber 104, including a central chamber 1041, which is arranged in the middle of the sealed chamber 104, and a first piston 1051 is arranged therein. The first piston 1051 extends upward to the outside of the central chamber 1041 through a first piston rod 1054 and is connected to a first top plate 1053, and when the first top plate 1053 is synchronously lifted with the lifting of the lifting assembly 102, it abuts against both sides of the tunnel reinforcement top support 101. The central chamber 1041 is used to provide air pressure to the stirring assembly 107 below through the first piston 1051, so as to press the filler in the stirring assembly 107 into the delivery pipe 1032 and deliver it to the filling airbag 1033.

[0070] In the embodiment of the present invention, the first piston rod 1054 is sleeved with a first return spring 1052 between the first top plate 1053 and the outer wall of the central chamber 1041 , so that the first piston 1051 can be automatically returned to its original position.

[0071] It is easy to understand that the first piston 1051 , the first return spring 1052 , the first top plate 1053 , and the first piston rod 1054 together constitute the first elastic piston assembly 105 .

[0072] Better, see Figure 7 The sealed chamber 104 also includes a side chamber 1042. The two side chambers 1042 are arranged at both ends of the sealed chamber 104 and are symmetrically distributed on both sides of the central chamber 1041. The sides thereof are provided with a feed port 1043 for pre-filling the filler, and the tops are provided with a vent hole 1044 for exhaust. The bottoms are connected with a group of stirring components 107 thereunder so as to deliver the filler to the stirring components 107 when they are lifted synchronously with the lifting of the lifting component 102.

[0073] In the embodiment of the present invention, combined with Figure 8, a second piston 1065 is arranged in the side chamber 1042, the second piston 1065 extends downward to the outside of the side chamber 1042 through the second piston rod 1061 and is connected to a support seat 1062, the second piston rod 1061 is sleeved with a second return spring 1063 between the support seat 1062 and the outer wall of the chamber 1042, and the second return spring 1063 is applied with a pre-tightening force in a natural state. With such a design, in the initial state, the support seat 1062 is supported on the base 1022 to support the sealed chamber 104, when the sealed chamber 104 is synchronously lifted with the lifting of the lifting assembly 102, the support seat 1062 leaves the base 1022, and under the push of the second return spring 1063, the second piston rod 1061 drives the second piston 1065 to move downward, pushing the filler in the side chamber 1042 into the stirring assembly 107.

[0074] It is easy to understand that the second piston 1065 , the second piston rod 1061 , the second return spring 1063 , and the support seat 1062 together constitute the second elastic piston assembly 106 .

[0075] Preferably, the second elastic piston assembly 106 is also provided with a guide sleeve 1064, which is fixedly connected to the bottom of the side chamber 1042, and the second piston rod 1061 is slidably connected in the guide sleeve 1064, so that the second piston rod 1061 can be kept to slide smoothly up and down through the guide sleeve 1064.

[0076] Continue to see Fig. 9 The embodiment of the present invention provides a specific stirring assembly 107, including a stirring tank body 1071 and a stirring shaft 1072. The two ends of the stirring tank body 1071 are connected to the side chamber 1042 through a one-way liquid inlet valve 1075, and the upper middle part thereof is gas-connected to the central chamber 1041 through at least one connecting pipe 1076, and the bottom is connected to the bottom end of the delivery pipe 1032; the stirring shaft 1072 is arranged in the stirring tank body 1071 and the two ends are rotatably fixed to the two ends of the stirring tank body 1071 through bearings 1074, and a plurality of blades 1073 are fixed on the stirring shaft 1072. The filler in the side chamber 1042 is transported to the stirring tank body 1071 by means of the one-way liquid inlet valve 1075, and the one-way liquid inlet valve 1075 can maintain one-way liquid inlet, so that the filler can smoothly enter the stirring tank body 1071, and the gas is prevented from entering the side chamber 1042, so that the second piston rod 1061 can be pushed down smoothly.

[0077] It should be noted that the connecting pipes where the one-way liquid inlet valves 1075 at both ends are located are fixedly sealed and connected to the middle connecting pipe 1076, and bear the weight of the stirring assembly 107. However, two auxiliary support wheels 1077 are connected to the bottom of the stirring tank body 1071, and two corresponding grooves are reserved on the base 1022. In the initial state, the two auxiliary support wheels 1077 are located in the two grooves, and the device can be supported by the auxiliary support wheels 1077, and the auxiliary support wheels 1077 have rolling properties, so that the device is more convenient to transfer.

[0078] In the embodiment of the present invention, combined with Fig.10 The stirring assembly 107 also includes a winding disk 1081, a winding rope 1083, and a reset torsion spring 1082, which together constitute a pull rope assembly 108. The pull rope assembly 108 is arranged at both ends of the outside of the stirring tank body 1071. Specifically, two sets of winding disks 1081 are fixedly arranged on one end of the stirring shaft 1072 extending out of the stirring tank body 1071, one end of the winding rope 1083 is wound around the winding disk 1081, and the other end is connected and fixed to the support base 1022. The reset torsion spring 1082 is arranged on the inner side of the winding disk 1081 and one end is fixedly connected to the bearing 1074. In this way, when the stirring assembly 107 is lifted together with the sealed chamber 104, since the other end of the winding rope 1083 is connected and fixed to the support base 1022, the winding rope 1083 will be pulled out from the winding state in the winding disk 1081, thereby driving the winding disk 1081 to rotate, and then the winding disk 1081 drives the stirring shaft 1072 to rotate, and the blade 1073 stirs and mixes the filler in the stirring tank body 1071.

[0079] It should be noted that the embodiment of the present invention uses two epoxy resins, epoxy resin A and epoxy resin B are respectively filled into the two side chambers 1042 from the feed port 1043, and when the sealed chamber 104 is lifted, the epoxy resins A and B in the two side chambers 1042 are squeezed by the second piston 1065 and pushed into the stirring tank body 1071 through the one-way liquid inlet valve 1075, and the epoxy resins A and B are fully stirred and mixed in the stirring tank body 1071.

[0080] In the embodiment of the present invention, Figure 3-4 Four conveying pipes 1032 are arranged, and the four conveying pipes 1032 are grouped in pairs, extending downward through the tunnel reinforcement top support 101, and are respectively connected to the stirring tank bodies 1071 of the two groups of stirring assemblies 107, so as to uniformly convey the filler into the filling airbag 1033.

[0081] In addition, a control valve 1031 may be further provided on the delivery pipeline 1032, and the delivery pipeline 1032 may be closed by the control valve 1031, thereby preventing the epoxy resin from flowing back downward.

[0082] Preferably, a certain length above the delivery pipe 1032 is designed as a hose structure, which allows the delivery pipe 1032 to be telescopic within a certain range, so that the filling airbag 1033 can be expanded smoothly and the tunnel reinforcement top support 101 can move smoothly.

[0083] The working principle of the rapid motorized tunnel reinforcement and repair device 100 provided by the present invention is:

[0084] The scissor-type telescopic bracket 1024 can be operated by the electric telescopic rod 1021 to push up the tunnel reinforcement top support 101. In this process, the sealed chamber 104 is simultaneously driven to move upward, and the upward movement of the sealed chamber 104 can drive the second piston rod 1061 and the support seat 1062 to leave the ground, and the second return spring 1063 releases the elastic force to move the second piston 1065 downward, so that the epoxy resins A and B in the two side chambers 1042 enter the stirring tank body 1071, and then the sealed chamber 104 moves upward, so that the winding disk 1081 releases the winding rope 1083, and the winding disk 1081 drives the stirring shaft 1072 and the blade 1073 to rotate to mix the epoxy resins A and B and keep the two liquids evenly mixed. When the scissor-type telescopic bracket 1024 is lifted to contact the tunnel reinforcement top support 101, the first top plate 1053 also abuts against the tunnel reinforcement top support 101, the first top plate 1053 is pressed down, and the first piston rod 1054 pushes the first piston 1051 downward to move, and the gas in the closed central chamber 1041 is pressed into the stirring tank 1071, thereby pressing the filler in it into the delivery pipe 1032 and delivering it to the filling airbag 1033. In this way, the dual support and reinforcement of the tunnel reinforcement top support 101 and the filling reinforcement assembly 103 can be achieved, which can not only realize the overall reinforcement of the tunnel, but also enable the local weak area to be well filled and reinforced, with a good reinforcement effect and easy and quick implementation.

[0085] The rapid motorized tunnel reinforcement and repair method using the above reinforcement and repair device is as follows:

[0086] S1, quickly and motorizedly deploy reinforcement and repair equipment in the tunnel to be reinforced and repaired;

[0087] The site can be divided into modular layout, with tunnel reinforcement top support 101 as a group, jacking assembly 102 as a group, sealing chamber 104 and mixing assembly 107 as a group. 3-5 soldiers or construction workers on site can carry it, and with the help of small lifting equipment when necessary. After the jacking assembly 102, sealing chamber 104 and mixing assembly 107 on both side walls of the tunnel are laid out, the tunnel reinforcement top support 101 is moved and placed on top, and the relevant pipelines are connected.

[0088] S2, synchronously lifting the tunnel reinforcement support 101 upwards by two sets of lifting assemblies 102;

[0089] Specifically, by operating the electric telescopic rod 1021 to retract, the electric telescopic rod 1021 drives the scissor-type telescopic bracket 1024 to unfold, and when unfolding, the upper fixed plate 1023 and the connecting plate 1028 can be pushed upward to move upward;

[0090] S3, during the ascending process of the lifting assembly 102, the sealed chamber 104 is synchronously lifted, and the second return spring 1063 drives the second piston 1065 to return downward to press the filler into the mixing tank body 1071;

[0091] S4, the stirring tank body 1071 moves upward synchronously, and the winding rope 1083 drives the winding disk 1081 to rotate, so that the stirring shaft 1072 drives the blades 1073 to stir and mix the filler;

[0092] S5, when the tunnel reinforcement top support 101 contacts the tunnel top wall and continues to lift, the first top plate 1053 abuts against the tunnel reinforcement top support 101, and the first piston 1051 moves downward to compress the gas into the central chamber 1042, and allows the filler to be filled into the filling air bag 1033 through the delivery pipe 1032 to fill the voids in the tunnel top wall, so that the tunnel reinforcement top support 101 evenly supports and reinforces the tunnel.
