Description

Technical Field

[0001] This application relates to the technical field of repairing cracks in ancient buildings, and in particular to a microbial concrete grouting device for the repair of ancient buildings. Background Technology

[0002] In the design and use of microbial grouting devices, the activity of microorganisms (such as Bacillus pasteurellii) is a prerequisite for the repair effect. Bacillus pasteurellii bacterial solution, calcium source (such as calcium nitrate), and nutrients (such as yeast extract) need to be stored separately (to avoid premature reaction that consumes nutrients or generates calcium carbonate that clogs the pipeline). The device needs to integrate a "real-time mixing module" (such as a three-way pipeline or a static mixer) to ensure that the mixture is mixed in the optimal ratio (usually bacterial solution: calcium source: nutrients = 1:1:0.5, which can be adjusted according to the strain) before grouting, and the mixing time should not exceed 30 minutes (to prevent microorganisms from multiplying prematurely due to excess nutrients after mixing).

[0003] Because ancient building walls are relatively old, they are prone to multiple or long cracks. For multiple or long cracks (>5m), the order of "from deep to shallow, from narrow to wide" should be followed. For example, first inject the deep narrow cracks (to avoid shallow wide cracks taking the grout first, which would result in the deep layer not being filled), and then inject the shallow wide cracks. If the crack has branches, the main crack should be injected first, and then the branch cracks should be injected (to prevent the branch grout from flowing back and blocking the main crack).

[0004] To flexibly adapt to cracks, handheld tubular grouting anchors are generally used. The tubular grouting anchor is a hollow tubular rod with openings at both ends. One end of the rod is the insertion end, and the other end is the injection end. During grouting, Pasteurella multocida solution, cementitious liquid, and concrete are mixed in proportion to form grouting liquid, which is injected into the rod through the injection end. Grouting is stopped when the grouting liquid flows out of the borehole.

[0005] However, since the grouting liquid needs to follow the principle of "mixing as needed and using immediately after mixing", it is necessary to quickly determine the depth of the cracks. Basically, the depth and width are determined by visual inspection and simple measurement, and the cracks are marked on the wall or in a notebook. However, during the actual grouting, only the grouting holes are left, and the rest of the cracks are sealed with sealing plates to prevent grout leakage. Transparent plates can be used for sealing, but it is still not possible to see the depth of the cracks directly, and there is a deviation in the size prediction. Summary of the Invention

[0006] To provide a more intuitive understanding of crack depth, this application offers a microbial concrete grouting device for the restoration of ancient buildings.

[0007] This application provides a microbial concrete grouting device for the restoration of ancient buildings, employing the following technical solution: A microbial concrete grouting device for the restoration of ancient buildings, comprising: A sealing plate, used to seal cracks, has through grooves that are spaced apart along the extension direction of the crack; The pre-embedded rod is inserted at an angle into the ancient building and connected to the sealing plate; A casting rod is vertically inserted into the crack through the through groove. One end of the casting rod abuts against the deep end of the crack, and the depth of the crack is indicated by the display position of the other end of the casting rod. The casting rods are spaced apart. A sealing block is slidably installed in the through groove. The sealing block has a through hole for the pouring rod to pass through. When the pouring rod passes through the sealing block, the crack is sealed. Multiple material tanks, each containing microbial bacteria, calcium salt solution, and nutrient mixture; A mixing tank, equipped with a stirring paddle, and connected to multiple of the aforementioned material tanks; A peristaltic pump, one end of which is connected to the mixing tank, and the other end of which is connected to the pouring rod and can be detachably connected; A trolley for transporting and holding the buckets; The mixing tank is equipped with a hanging rod. When the peristaltic pump is connected to the pouring rod inserted deep into the crack, the hanging rod is connected to the pouring rod inserted shallowly into the crack. The mixing tank is coaxially mounted with a rotating ring, which is rotatably mounted about its own central axis. The rotating ring is slidably connected along the axial direction of the mixing tank, and the hanging rod is mounted on the rotating ring. A screw is threaded onto the rotating ring, and the screw abuts against the mixing tank; The hanging rod is hinged with a connecting ring, which is connected to the pouring rod. The peristaltic pump and one axial end of the mixing tank are connected by a hose. When the rotating ring is slid, the mixing tank can be driven to slide along its own axis and slide connected to the rotating ring, so that the mixing tank is tilted.

[0008] By adopting the above technical solution, the pre-embedded rod is inserted obliquely into the ancient building. The sealing plate is fixed by the insertion of the pre-embedded rod and the sealing plate, and the sealing plate initially seals the crack. Then, the sealing block is slid into the through grooves set at intervals along the extension direction of the crack on the sealing plate, so that the perforation of the sealing block is connected to the through groove. The sealing block further seals the crack. The pouring rod is passed through the perforation of the sealing block and the through groove, and vertically inserted into the crack until one end abuts the deep end of the crack. By observing the displayed position of the other end of the pouring rod on the outside of the sealing plate, the crack depth can be intuitively obtained without relying on pre-marking or visual estimation. The operator then pours the pouring rod according to the crack depth. Based on the length displayed on the grouting pole, prioritize connecting the deepest grouting pole, start the peristaltic pump, and inject fresh mixed grout into the crack. After filling one area, move to the next (shallower) grouting pole to continue grouting. Use a trolley to transport multiple buckets containing microbial bacteria, calcium salt solution, and nutrient mixture to avoid material mixing or premature reaction. When grouting is required, introduce the three materials into a mixing tank with a stirring paddle for rapid and uniform mixing, and then use a peristaltic pump (detachably connected to the grouting pole) to deliver the mixture to the grouting pole. The spaced grouting poles are suitable for scenarios with multiple or long cracks. The hanging rod can provide some support and fixation for the mixing tank during the grouting process. After connecting the peristaltic pump to the pouring rod inserted deep into the crack, connect the hanging rod to the pouring rod inserted shallow into the crack to keep the mixing tank relatively stable during the grouting process. During the grouting process, the rotating ring is rotated and slid according to the actual situation of the cracks to bring the hanging rod to the appropriate position so as to better support and fix the mixing tank. The screw is threadedly connected to the rotating ring and abuts against the mixing tank. After the rotating ring is adjusted to the appropriate position, the position of the rotating ring can be fixed by tightening the screw, preventing the rotating ring from moving randomly during the grouting process, ensuring the stability of the hanging rod, and thus ensuring the stability of the mixing tank. The hinged design of the connecting ring makes the connection between the hanging rod and the pouring rod more flexible and can adapt to the connection requirements of different angles. Due to the hinged relationship between the hanging rod and the connecting ring, the mixing tank can be rotated by rotating the hanging rod and sliding the rotating ring. The tilting discharge angle of the mixing tank can be adjusted as needed during the grouting process, so that the mixture can be injected into the cracks more smoothly, improving the grouting effect and efficiency.

[0009] Optionally, the hanging rod is a telescopic rod.

[0010] By adopting the above technical solution, the design of the hanging rod as a telescopic rod further increases the flexibility of its length adjustment. The length of the hanging rod can be adjusted more precisely according to the crack depth and the position of the mixing tank, making the connection between the hanging rod and the pouring rod more suitable, better meeting the grouting needs of cracks at different depths, and improving the adaptability and ease of operation of the device.

[0011] Optionally, a partition is installed inside the mixing tank. The partition is inclined along the axial direction of the mixing tank and divides the inner cavity of the mixing tank into two receiving chambers. The two receiving chambers are used alternately. When one receiving chamber is used to stir the mixture, the other receiving chamber is filled with sterile water. The mixing tank has a feed port and a discharge port installed at both ends of its axial direction. The hose is inserted into the discharge port. The feed port and discharge port at the same end of the mixing tank are respectively connected to two receiving cavities. The space of the receiving cavity gradually decreases along the discharge direction of the mixture. The stirring paddle is close to the feed port. During the grouting process, the rotating ring slides along the mixing tank in a direction away from the ancient building, causing the discharge port of the mixing tank to rotate downward.

[0012] By adopting the above technical solution, the partition divides the mixing tank into two chambers for alternating use: one for stirring the mixture and the other for filling with sterile water. This prevents the mixture from solidifying and remaining in the mixing tank, ensuring the mixing effect and normal operation of the device during subsequent uses. The chamber space gradually narrows along the discharge direction, facilitating the smooth flow of the mixture. The stirring paddle, located near the inlet port, quickly stirs and mixes the incoming material. During grouting, the rotating ring slides, causing the outlet port to rotate downwards. This allows adjustment of the discharge angle according to the crack conditions, improving the accuracy and effectiveness of grouting.

[0013] Optionally, the stirring paddle is configured according to the receiving cavity. The stirring paddle is close to the feed port. The stirring paddle includes a rotating rod and a first blade. The rotating rod includes a first rod and a second rod. The second rod is slidably mounted on the first rod. The first rod passes through a partition. The second rod extends into another receiving cavity. The first blade is fixedly mounted on the first rod. A second blade is mounted on the second rod. The second blade is close to the discharge port.

[0014] By adopting the above technical solution, the stirring paddle is specially designed and configured according to the corresponding receiving cavity. The first rod passes through the partition, and the second rod can slide into another receiving cavity. This design allows one stirring paddle to simultaneously agitate two receiving cavities, and the sterile water is also stirred, thus better rinsing away residual coagulated substances.

[0015] Optionally, when the second blade is above the first blade, the second rod and the first rod are rotatably connected; when the second blade is below the first blade, the second rod rotates along with the rotation of the first rod.

[0016] By adopting the above technical solution, during the stirring process, the second rod automatically adjusts its rotation mode according to the position of the second blade relative to the first blade. When the second blade is above the first blade, the first blade is in contact with the sterile liquid, and the second blade is in contact with the mixture and close to the discharge port. The second rod and the first rod are rotatably connected. The second blade does not stir the mixture along with the first blade, while the first blade in contact with the mixture stirs the sterile liquid, thus achieving proper stirring of the mixture. This ensures that the mixture is properly stirred and does not react prematurely. Both the first and second blades in contact with the sterile liquid can stir the sterile liquid, allowing it to effectively clean the receiving cavity.

[0017] In summary, this application includes at least one of the following beneficial effects: 1. By using the casting rod itself as a depth gauge, the true depth of the crack can be directly and intuitively displayed while sealing the plate, thus fundamentally eliminating the prediction error; 2. The mixing tank is designed with two chambers, which can be used for grouting in one chamber and cleaning or material preparation in the other chamber. This ensures that fresh and highly active mixed grout can be provided continuously when repairing long or multiple cracks, while avoiding cross-contamination of different batches of grout or equipment blockage.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail.

[0021] This application discloses a microbial concrete grouting device for the restoration of ancient buildings. The overall design aims to efficiently and accurately complete the repair of cracks in ancient buildings.

[0022] Reference Figure 1 For example, the cracks in the walls of ancient buildings often meander in an irregular direction and vary in depth.

[0023] Reference Figure 1 and Figure 2 In practice, the first step is to seal the cracks and measure their depth. The microbial concrete grouting device used for ancient building restoration includes a sealing plate 100, an embedded rod 200, a pouring rod 300, and a sealing block 400. The pouring rod 300 has a uniform length. The sealing plate 100 is a rectangular plate structure made of transparent or semi-transparent material to allow observation of the internal structure. The sealing plate 100 is used to cover and seal wall cracks, and multiple through slots 110 are spaced apart along the direction of the crack. The embedded rod 200 is a metal rod that is inserted into the ancient building wall at a certain angle and reliably connected to the sealing plate 100 through a plug-in method, thus firmly fixing the sealing plate 100 to the crack surface. The sealing plate 100 plays a preliminary role in sealing the cracks.

[0024] Reference Figure 2 The sealing block 400 is slidably installed into the through groove 110. The length of the sealing block 400 is greater than the maximum width of the crack. The sealing block 400 is provided with a through hole 410 to provide a channel for the subsequent insertion of the pouring rod 300. The sealing block 400 and the sealing plate 100 together form a complete seal for the crack, preventing grout leakage during grouting.

[0025] Reference Figure 3The casting rod 300 is a hollow tubular structure with a pointed end into which it is inserted. A casting hole is formed in the rod wall near the pointed end. It is vertically inserted into the crack through a through-slot 110 on the sealing plate 100 until the pointed end reaches the deepest point of the crack. Multiple casting rods 300 are arranged at intervals along the crack, and their centerlines are not aligned. The lengths of the casting rods extending beyond the crack also vary. By observing the position of the other end of the casting rod outside the sealing plate 100, the crack depth information can be obtained intuitively and accurately. The spaced arrangement of the casting rods 300 can accommodate the repair needs of multiple or long cracks in ancient buildings.

[0026] Reference Figure 3 and Figure 4 The microbial concrete grouting device for ancient building restoration also includes multiple material tanks 600, a mixing tank 500, a peristaltic pump 700, and a trolley 800. The multiple material tanks 600 are placed side-by-side on the trolley 800, each independently storing microbial inoculum, calcium salt solution, and nutrient mixture, preventing premature reaction of the raw materials from the source. The mixing tank 500 is connected to each material tank 600 via pipelines. A stirring paddle 900 is mounted inside the mixing tank 500, preferably manually controlled, to stir and form a highly active microbial grouting solution, reducing the risk of premature reaction due to excessive speed.

[0027] Reference Figure 5 and Figure 6 The mixing tank 500 has a cylindrical structure. Both ends of the mixing tank 500 have a discharge port 510 and a feed port 520. The discharge port 510 is connected to the peristaltic pump 700 via a flexible hose 530, and the feed port 520 is connected to three feed tanks 600 via three feed pipes. A rotating ring 540 is coaxially fitted onto the outer peripheral wall of the mixing tank 500. The rotating ring 540 can rotate around the axis of the mixing tank 500 and slide along the axial direction of the mixing tank 500.

[0028] Reference Figure 4 and Figure 5 A hanging rod 550 is fixedly installed on the rotating ring 540. The hanging rod 550 is a telescopic rod structure, which can be fixed after telescopic movement. The end of the hanging rod 550 away from the rotating ring 540 is hinged to a connecting ring 560. The connecting ring 560 is a ring structure that can be sleeved on the outer end of the pouring rod 300 inserted into the shallow crack, realizing the connection between the hanging rod 550 and the shallow pouring rod 300. A screw 541 is also threadedly connected to the rotating ring 540. One end of the screw 541 passes through the rotating ring 540 and abuts against the outer peripheral wall of the mixing tank 500. When the rotating ring 540 is adjusted to the appropriate position, tightening the screw 541 can fix the rotating ring 540 by friction and prevent it from shifting during grouting.

[0029] Reference Figure 6Since the peristaltic pump 700 is connected to one axial end of the mixing tank 500 via a flexible hose 530, the deformation characteristics of the flexible hose 530 provide rotation space for the mixing tank 500. When the hanging rod 550 is rotated, the hanging rod 550 and the rotating ring 540 are hinged, and the axial direction of the mixing tank 500 moves axially along the rotation of the rotating ring 540. The rotation of the hanging rod 550 can drive the mixing tank 500 and the hanging rod 550 to slide relative to each other, thereby adjusting the discharge angle.

[0030] Reference Figure 7 The other end of the peristaltic pump 700 is connected to the pouring rod 300 in a sealed manner. A support base 120 is detachably inserted into the sealing plate 100. The sealing plate 100 has an insertion hole 140. The support base 120 includes a support rod 121 and a support plate 122. The support rod 121 is inserted into the sealing block 400. The support plate 122 is used to contact and support the peristaltic pump 700, so that the peristaltic pump 700 can maintain a stable state for conveying the mixture. Furthermore, the bottom of the peristaltic pump 700 and the support plate 122 can form a magnetic attraction, or the peristaltic pump 700 can be temporarily fixed to the support plate 122 with bolts. The peristaltic pump 700 can be further fixed according to the needs of the construction site.

[0031] Reference Figure 6 Inside the mixing tank 500, a partition 570 is fixedly installed. The partition 570 is inclined along the axial direction of the mixing tank 500, dividing the inner cavity of the mixing tank 500 into two independent receiving chambers 580. The two receiving chambers 580 can be used alternately. When one receiving chamber 580 is filled with material and mixed by the stirring paddle 900, the other receiving chamber 580 can be cleaned by filling it with sterile water through a dedicated pipeline to prevent residual mixture from solidifying and clogging. The space of the receiving chamber 580 gradually narrows along the discharge direction of the mixture to promote the collection of the mixture towards the discharge port 510 and reduce residue.

[0032] Reference Figure 6 The stirring paddle 900 is configured according to the receiving cavity 580, including a rotating rod 910 and a first blade 920. The rotating rod 910 is composed of a first rod 911 and a second rod 912. The first rod 911 passes laterally through the central hole of the partition 570 and is rotatably connected to the partition 570. The second rod 912 is slidably sleeved on one end of the first rod 911 and can extend and retract along the axial direction of the first rod 911, so that the second rod 912 can extend into the receiving cavity 580 on the other side. The first blade 920 is fixedly installed on the part of the first rod 911 located in one of the receiving cavities 580, close to the feed port 520 corresponding to the receiving cavity 580. A second blade 930 is fixedly installed on the second rod 912, and the second blade 930 is located in the other receiving cavity 580 and close to its corresponding discharge port 510.

[0033] Reference Figure 6 and Figure 8The first rod 911 has a locking block 913 inside, and the second rod 912 has two sliding rings 914 fixedly inserted into its wall, one of which has a locking groove 915. The second rod 912 is installed on the first rod 911 first, and then the locking block 913 is installed. When the second blade 930 is above the first blade 920, the locking groove 915 is away from the locking block 913, and the second rod 912 is rotatably connected to the first rod 911, meaning that the second rod 912 can remain stationary when the first rod 911 rotates. When the second blade 930 is below the first blade 920, the second rod 912 slides under the action of gravity, causing the locking groove 915 of the sliding ring 914 and the locking block 913 to engage, allowing it to rotate synchronously with the first rod 911 to adapt to the stirring needs of different cavities 580.

[0034] Reference Figure 6 When the second blade 930 is above the first blade 920, the first blade 920 is in contact with the sterile liquid, and the second blade 930 is in contact with the mixture and is close to the discharge port 510. The second rod 912 and the first rod 911 are rotatably connected. When the rotating rod 910 is manually rotated, the first blade 920 stirs the sterile liquid, but the second blade 930 does not stir the mixture along with the first blade 920. Only the first blade 920 stirs the mixture in the container 580 containing the mixture, and the first blade 920 is completely immersed in the mixture, thus fully stirring it.

[0035] Sterile water forms a "circulating scouring" effect under stirring, generating uniform shearing and impact forces on the tank wall and blades. This can quickly peel off the attached residual slurry, especially removing residues from "dead corner areas" (such as the arc transition at the bottom of the mixing tank 500 and the connection gap between the blades and the shaft). Compared with static cleaning, dynamic stirring can shorten the cleaning time. Both the first blade 920 and the second blade 930 can stir the sterile liquid, achieving a "highly efficient, uniform, and gentle" cleaning effect through dynamic scouring.

[0036] The implementation principle of a microbial concrete grouting device for the restoration of ancient buildings according to an embodiment of this application is as follows: First, the embedded rod 200 is inserted obliquely into the crack in the ancient building wall. The sealing plate 100 is fixed by the insertion of the embedded rod 200 and the sealing plate 100, so that the sealing plate 100 fits against the crack surface. Then, the sealing block 400 is slid into the through groove 110, so that the through hole 410 is aligned with the through groove 110. The pouring rod 300 is inserted into the crack through the through hole 410. After determining the depth by the position indicator on the outer end, the hose 530 of the peristaltic pump 700 is connected to the deep pouring rod 300 according to the crack depth. The connecting ring 560 of the hanging rod 550 is sleeved on the shallow pouring rod 300. The material tank 600 valve directs the material into one of the receiving chambers 580 of the mixing tank 500 according to the ratio. First, the mixing tank 500 is set horizontally. After the mixture is mixed, the rotating ring 540 is slid and rotated to adjust the angle of the mixing tank 500. The peristaltic pump 700 is started to inject the mixture into the crack. The idle receiving chamber 580 is filled with sterile water for cleaning. During the mixing process, the connection between the second blade 930 and the first rod 911 is adjusted according to the position of the second blade to ensure uniform mixing. When grouting, the pouring rod 300 is switched sequentially in the order of "from deep to shallow" to complete the entire crack repair.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
