Description

TECHNICAL FIELD

[0001] The application relates to the technical field of crack repair of ancient buildings, in particular to a microbial concrete grouting device for repairing ancient buildings. BACKGROUND

[0002] In the design and use of the microbial grouting device, the activity of microorganisms (such as Bacillus pasteurii) is the premise of the repair effect. Bacillus pasteurii bacterial solution, calcium source (such as calcium nitrate) and nutrient substance (such as yeast extract) need to be stored separately (to avoid premature reaction to consume nutrients or generate calcium carbonate to block the pipeline), and the device needs to integrate a "real-time mixing module" (such as a three-way pipeline and a static mixer) to ensure that the mixture is mixed in the best ratio (usually bacterial solution: calcium source: nutrient = 1:1:0.5, adjusted according to the strain) before grouting, and the mixing time is not more than 30 minutes (to prevent the microorganisms from reproducing prematurely due to excessive nutrients after mixing).

[0003] Since the wall of the ancient building has been used for a long time, it is generally prone to multiple cracks or long cracks. For multiple cracks or long cracks (> 5m), the order of "from deep to shallow, from narrow to wide" needs to be followed, for example, first injecting into deep narrow cracks (to avoid the priority of shallow wide cracks to absorb grout, resulting in incomplete filling of deep cracks), and then injecting into shallow wide cracks; if the crack has branches, the main crack needs to be injected first, and then the branch crack (to prevent the branch grout from flowing back and blocking the main crack).

[0004] In order to flexibly adapt to cracks, a handheld tubular grouting anchor is 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, Bacillus pasteurii bacterial solution, cementing 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 on demand and using immediately after mixing", the depth and width of the crack need to be determined quickly. Basically, the depth and width are known by visual observation and simple measurement, and the crack condition is marked on the wall or the book. However, only the grouting hole is left during formal grouting, and the rest of the cracks are sealed with a sealing plate to prevent grout leakage. The sealing plate can be a transparent plate, but the crack depth cannot be directly observed, and there is a size prediction deviation. SUMMARY

[0006] In order to more intuitively feel the crack depth, the application provides a microbial concrete grouting device for repairing ancient buildings.

[0007] The application provides a microbial concrete grouting device for repairing ancient buildings, which adopts the following technical scheme:

[0008] A microbial concrete grouting device for repairing ancient buildings comprises:

[0009] A sealing plate, used to seal cracks, has through grooves that are spaced apart along the extension direction of the crack;

[0010] The pre-embedded rod is inserted at an angle into the ancient building and connected to the sealing plate;

[0011] 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.

[0012] 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.

[0013] Multiple material tanks, each containing microbial bacteria, calcium salt solution, and nutrient mixture;

[0014] A mixing tank, equipped with a stirring paddle, and connected to multiple of the aforementioned material tanks;

[0015] 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;

[0016] A trolley for transporting and holding the buckets;

[0017] 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.

[0018] 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.

[0019] A screw is threaded onto the rotating ring, and the screw abuts against the mixing tank;

[0020] 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.

[0021] By adopting the above technical scheme, the embedded rod is obliquely inserted into the ancient building, the embedded rod and the sealing plate are inserted to realize the fixation of the sealing plate, and the sealing plate preliminarily seals the cracks; subsequently, the sealing block is slid into the through groove arranged along the crack extension direction at intervals, the through hole of the sealing block is communicated with the through groove, the sealing block further seals the cracks, the pouring rod is passed through the through hole of the sealing block and the through groove, and is vertically inserted into the cracks until one end abuts against the deep end of the cracks; the crack depth is intuitively obtained by observing the display position of the other end of the pouring rod outside the sealing plate, and it is not necessary to rely on prior marking or visual observation; the operator preferentially selects the pouring rod connected to the deepest part according to the length displayed by the pouring rod, starts the peristaltic pump, and injects fresh mixed slurry into the cracks; after one place is filled, the next (shallower) pouring rod is moved to continue grouting; the multiple barrels respectively containing microbial bacteria, calcium salt solution and nutrient mixture are transported by using a cart, so that the materials are prevented from being confused or prematurely reacted; when grouting is needed, the three materials are introduced into the stirring barrel with a stirring paddle to be quickly and uniformly mixed, and then the mixed liquid is delivered to the pouring rod by the peristaltic pump (detachably connected with the pouring rod); the interval arrangement of the pouring rods is suitable for the scene of multiple cracks or long cracks;

[0022] The hanging rod can support and fix the stirring barrel during grouting; after the peristaltic pump is connected with the pouring rod inserted into the deep part of the cracks, the hanging rod is connected with the pouring rod inserted into the shallow part of the cracks, so that the stirring barrel remains relatively stable during grouting.

[0023] During grouting, the hanging rod reaches the appropriate position by rotating and sliding the rotating ring according to the actual situation of the cracks, so as to better support and fix the stirring barrel.

[0024] The screw rod is threadedly connected with the rotating ring and abuts against the stirring barrel; after the rotating ring is adjusted to the appropriate position, the position of the rotating ring can be fixed by tightening the screw rod, so as to prevent the rotating ring from moving randomly during grouting, ensure the stability of the hanging rod, and further ensure the stability of the stirring barrel.

[0025] The hinged design of the connecting ring makes the connection between the hanging rod and the pouring rod more flexible, and can adapt to different connection requirements; since the hanging rod and the connecting ring are hinged, the stirring barrel can be rotated by rotating the hanging rod and sliding the rotating ring; the inclination angle of the stirring barrel can be adjusted as needed during grouting, so that the mixed liquid is more smoothly injected into the cracks, and the grouting effect and efficiency are improved.

[0026] Optionally, the hanging rod is a telescopic rod.

[0027] By adopting the above technical scheme, the hanging rod is designed as a telescopic rod, which further increases the flexibility of length adjustment; the length of the hanging rod can be more accurately adjusted according to the crack depth and the position of the stirring barrel, so that the connection between the hanging rod and the pouring rod is more appropriate, the grouting demand of cracks with different depths is better met, and the adaptability and operation convenience of the device are improved.

[0028] Optionally, a partition is installed in the stirring barrel, the partition is arranged in an axial direction of the stirring barrel, and the partition divides the stirring barrel into two accommodating cavities, the two accommodating cavities are used alternately, when one of the accommodating cavities is used for stirring and mixing, the other accommodating cavity is filled with sterile water.

[0029] The stirring barrel is provided with a feeding port and a discharging port at each end in the axial direction, the hose is inserted into the discharging port, the feeding port and the discharging port at the same end of the stirring barrel are respectively communicated with the two accommodating cavities, the space of the accommodating cavities gradually decreases in the discharging direction of the mixing liquid, the stirring paddle is close to the feeding port, and during the grouting process, the swivel ring slides along the stirring barrel away from the ancient building, so that the discharging port of the stirring barrel is rotated downward.

[0030] By using the above technical scheme, the partition divides the stirring barrel into two accommodating cavities which are used alternately, one is used for stirring and mixing, and the other is filled with sterile water, so that the mixing liquid can be prevented from remaining and solidifying in the stirring barrel, and the mixing effect and normal operation of the device can be ensured during the next use. The space of the accommodating cavities gradually decreases in the discharging direction, which is beneficial to the smooth flow of the mixing liquid. The stirring paddle close to the feeding port can quickly stir and mix the entering materials. During the grouting process, the swivel ring slides to rotate the discharging port downward, the discharging angle can be adjusted according to the crack condition, and the accuracy and effect of grouting are improved.

[0031] Optionally, the stirring paddle is arranged correspondingly according to the accommodating cavities, the stirring paddle is close to the feeding port, the stirring paddle comprises a rotating rod and a first paddle blade, the rotating rod comprises a first rod and a second rod, the second rod is slidably installed on the first rod, the first rod penetrates through the partition, the second rod extends into the other accommodating cavity, the first paddle blade is fixedly installed on the first rod, the second rod is provided with a second paddle blade, and the second paddle blade is close to the discharging port.

[0032] By using the above technical scheme, the stirring paddle is arranged correspondingly according to the accommodating cavities and has a special structure, the first rod penetrates through the partition, and the second rod can slidably extend into the other accommodating cavity. This design enables one stirring paddle to simultaneously stir the two accommodating cavities, and the sterile water is also stirred to better flush the remaining solidified materials.

[0033] Optionally, when the second paddle blade is located above the first paddle blade, the second rod and the first rod are rotationally connected, and when the second paddle blade is located below the first paddle blade, the second rod rotates along with the rotation of the first rod.

[0034] By adopting the technical scheme, in the stirring process, the second rod automatically adjusts the rotating mode according to the position of the second paddle relative to the first paddle. When the second paddle is above the first paddle, the first paddle contacts the sterile liquid, the second paddle contacts the mixed liquid, and is close to the discharge port, the second rod is rotationally connected with the first rod, the second paddle does not stir the mixed liquid by rotating with the first paddle, and the first paddle in contact with the mixed liquid stirs the sterile liquid, so that the mixed liquid is reasonably stirred, and the mixed liquid can be reasonably stirred and not react in advance, but the first paddle and the second paddle in contact with the sterile liquid can stir the sterile liquid, so that the sterile liquid can be well cleaned in the containing cavity.

[0035] In summary, the present application includes at least one of the following beneficial effects:

[0036] 1. The pouring rod itself is used as a depth scale, and the real depth of the crack is directly and intuitively displayed while the sealing plate is blocked, which fundamentally eliminates the prediction deviation;

DETAILED DESCRIPTION

[0047] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 8 The present application will be further described in detail.

[0048] The embodiment of the present application discloses a microbial concrete grouting device for ancient building repair, and the whole design aims to efficiently and accurately complete the repair work of cracks in ancient buildings.

[0049] Referring to Figure 1 For example, the winding direction of cracks on the wall of an ancient building is usually irregular, and the depth is also different.

[0050] Referring to Figure 1 and Figure 2 In actual operation, first, crack sealing and depth measurement are performed. The microbial concrete grouting device for ancient building repair includes a sealing plate 100, a pre-buried rod 200, a pouring rod 300 and a sealing block 400, and the pouring rod 300 has a uniform length. The sealing plate 100 is a rectangular plate structure made of transparent or translucent material, so as to observe the internal situation. The sealing plate 100 is used for covering and sealing the cracks of the wall body, and a plurality of through slots 110 are arranged at intervals along the extension direction of the cracks. The pre-buried rod 200 is a metal rod piece, which is inserted into the interior of the wall of the ancient building at a certain inclination angle, and is reliably connected with the sealing plate 100 through insertion, so as to firmly fix the sealing plate 100 on the surface of the cracks, and the sealing plate 100 plays a role of initially sealing the cracks.

[0051] Referring to Figure 2 The sealing block 400 is slidably installed into the through slot 110, the length of the sealing block 400 is greater than the maximum width of the cracks, and the sealing block 400 is provided with a perforation 410, which provides a channel for the subsequent insertion of the pouring rod 300. The sealing block 400 and the sealing plate 100 jointly form a complete seal for the cracks, so as to prevent leakage of slurry during grouting.

[0052] Referring to Figure 3The pouring rod 300 is a hollow tubular structure, one end of the pouring rod 300 is a pointed end, a pouring hole is arranged on the rod wall close to the pointed end, the pouring rod 300 is vertically inserted into the crack through the through groove 110 on the sealing plate 100 until the pointed end abuts at the endpoint of the deepest part of the crack, a plurality of pouring rods 300 are arranged at intervals along the crack, the center lines of the plurality of pouring rods 300 are not on the same straight line, and the lengths of the pouring rods 300 extending out of the crack are also different. The crack depth information can be obtained intuitively and accurately by observing the display position of the other end of the pouring rod 300 outside the sealing plate 100. Since the pouring rods 300 are arranged at intervals, the repair requirements of multiple cracks or long cracks on ancient buildings can be met.

[0053] With reference to Figure 3 and Figure 4 The microbial concrete grouting device for repairing ancient buildings also comprises a plurality of material barrels 600, a stirring barrel 500, a peristaltic pump 700, and a cart 800. The plurality of material barrels 600 are arranged side by side on the cart 800 and are respectively used for independently storing microbial liquid, calcium salt solution, and nutrient mixture, so as to avoid the reaction of raw materials in advance from the source, and the stirring barrel 500 is in communication with each material barrel 600 through a pipeline. A stirring paddle 900 is rotatably installed in the stirring barrel 500, and the stirring paddle 900 is preferably manually controlled to stir the microbial grouting liquid with high activity and reduce the early reaction caused by too fast speed.

[0054] With reference to Figure 5 and Figure 6 The stirring barrel 500 is a cylindrical structure, and the two ends of the stirring barrel 500 in the axial direction are respectively provided with a discharge port 510 and a feeding port 520. The discharge port 510 is connected with the peristaltic pump 700 through a hose 530, and the feeding port 520 is connected with the three material barrels 600 through three feeding pipes. A rotating ring 540 is coaxially sleeved on the outer peripheral wall of the stirring barrel 500, and the rotating ring 540 can rotate around the axis of the stirring barrel 500 or slide along the axial direction of the stirring barrel 500.

[0055] With reference to Figure 4 and Figure 5 A hanging rod 550 is fixedly installed on the rotating ring 540, and the hanging rod 550 is a telescopic rod structure and can be fixedly kept after telescopic movement. The distal end of the hanging rod 550 away from the rotating ring 540 is hingedly connected with a connecting ring 560, and the connecting ring 560 is a ring structure and can be sleeved on the outer end of the pouring rod 300 inserted into the shallow part of the crack to realize the connection between the hanging rod 550 and the shallow pouring rod 300. A screw rod 541 is also threadedly connected to the rotating ring 540, one end of the screw rod 541 penetrates through the rotating ring 540 and abuts against the outer peripheral wall of the stirring barrel 500. When the rotating ring 540 is adjusted to a suitable position, the screw rod 541 can be tightened to fix the rotating ring 540 by friction force, so as to prevent the rotating ring 540 from being displaced during the grouting process.

[0056] With reference to Figure 6As the peristaltic pump 700 is connected with one end of the stirring barrel 500 in axial direction through the hose 530, the deformation characteristics of the hose 530 provide the stirring barrel 500 with rotation space. When the hanging rod 550 is rotated, the hanging rod 550 and the connecting ring 560 are hinged, and the axial direction of the stirring barrel 500 is axially moved along the rotation of the rotating ring 540. The rotation of the hanging rod 550 can drive the relative sliding of the stirring barrel 500 and the rotating ring 540, so as to adjust the discharging angle.

[0057] With reference to Figure 7 The other end of the peristaltic pump 700 is sealingly connected with the pouring rod 300 in plug-in mode. The support seat 120 is detachably plugged on the sealing plate 100. The sealing plate 100 is provided with the insertion hole 140. The support seat 120 comprises the support rod 121 and the support plate 122. The support rod 121 is plugged on the plugging block 400. The support plate 122 is used to contact and support the peristaltic pump 700, so that the peristaltic pump 700 can be kept in a stable state for conveying the mixed liquid. In addition, the bottom of the peristaltic pump 700 and the support plate 122 can be magnetically attracted, or the peristaltic pump 700 is temporarily fixed on the support plate 122 by bolts, so as to further fix the peristaltic pump 700 according to the needs of the construction site.

[0058] With reference to Figure 6 The stirring barrel 500 is further provided with the partition plate 570 which is fixedly installed inside the stirring barrel 500 and is arranged in an inclined manner along the axial direction of the stirring barrel 500. The stirring barrel 500 is divided into two independent accommodating cavities 580. The two accommodating cavities 580 can be alternately used. When one of the accommodating cavities 580 is filled with materials and is stirred and mixed by the stirring paddle 900, the other accommodating cavity 580 can be timely filled with sterile water for cleaning, so as to avoid the solidification and blockage of the residual mixed liquid. The space of the accommodating cavity 580 is gradually reduced along the discharging direction of the mixed liquid, so as to promote the collection of the mixed liquid to the discharging port 510 and reduce the residual amount.

[0059] With reference to Figure 6 The stirring paddle 900 is correspondingly arranged according to the accommodating cavities 580 and comprises the rotating rod 910 and the first paddle 920. The rotating rod 910 is composed of the first rod 911 and the second rod 912. The first rod 911 is transversely arranged through the center hole of the partition plate 570 and is rotationally connected with the partition plate 570. The second rod 912 is slidingly sleeved on one end of the first rod 911 and can be axially extended and retracted, so that the second rod 912 can be extended into the other accommodating cavity 580. The first paddle 920 is fixedly installed on the portion of the first rod 911 located in one of the accommodating cavities 580 and is close to the corresponding material inlet port 520 of the accommodating cavity 580. The second paddle 930 is fixedly installed on the second rod 912 and is located in the other accommodating cavity 580 and is close to the corresponding discharging port 510.

[0060] With reference to Figure 6 and Figure 8The first rod 911 is provided with a clamping block 913, and the rod wall of the second rod 912 is fixedly provided with two sliding rings 914, one of which is provided with a clamping groove 915. The second rod 912 is first installed on the first rod 911, and then the clamping block 913 is installed. When the second paddle 930 is located above the first paddle 920, the clamping groove 915 is away from the clamping block 913, and the second rod 912 is rotationally connected with the first rod 911, that is, the second rod 912 can remain stationary when the first rod 911 rotates. When the second paddle 930 is located below the first paddle 920, the second rod 912 slides under the action of gravity, so that the clamping groove 915 of the sliding ring 914 and the clamping block 913 are clamped, and the second rod 912 can rotate synchronously with the first rod 911 to adapt to the stirring requirements of different accommodating cavities 580.

[0061] With reference to Figure 6 When the second paddle 930 is located above the first paddle 920, the first paddle 920 is in contact with the sterile liquid, the second paddle 930 is in contact with the mixed liquid, and is close to the discharge port 510, and the second rod 912 is rotationally connected with the first rod 911. When the rotating rod 910 is manually rotated, the first paddle 920 stirs the sterile liquid, and the second paddle 930 does not rotate with the first paddle 920 to stir the mixed liquid. Only the first paddle 920 stirs the mixed liquid in the accommodating cavity 580 containing the mixed liquid, and the first paddle 920 is completely immersed in the mixed liquid to fully stir the mixed liquid.

[0062] The sterile water forms a "circulating flushing" under the action of stirring, and generates uniform shearing force and impact force on the barrel wall and the paddle, which can quickly strip the attached residual slurry, especially the residual in the "dead angle area" (such as the bottom arc transition of the stirring barrel 500, the connecting gap between the paddle and the shaft). Compared with static cleaning, dynamic stirring can shorten the cleaning time. The first paddle 920 and the second paddle 930 can both stir the sterile liquid, and realize "high efficiency, uniformity and gentleness" of cleaning through dynamic flushing.

[0063] The implementation principle of the microbial concrete grouting device for ancient building restoration is:

[0064] Firstly, the embedded rod 200 is obliquely inserted into the crack of the ancient building wall, the sealing plate 100 is fixed by the embedded rod 200 and the plug-in of the sealing plate 100, so that the sealing plate 100 is attached to the surface of the crack, then the sealing block 400 is slid into the through slot 110, the through hole 410 is aligned with the through slot 110, the pouring rod 300 is inserted into the crack through the through hole 410, the depth is determined by the outer end display position, then according to the crack depth, the hose 530 of the peristaltic pump 700 is connected with the deep pouring rod 300, the connecting ring 560 of the hanging rod 550 is sleeved on the shallow pouring rod 300, the valve of the material barrel 600 is opened, the material is introduced into one of the accommodating cavities 580 of the stirring barrel 500 in proportion, the stirring barrel 500 is first arranged horizontally, after the mixed liquid is stirred, the stirring barrel 500 is adjusted in angle by sliding and rotating the rotating ring 540, the mixed liquid is injected into the crack by starting the peristaltic pump 700, the idle accommodating cavity 580 is filled with sterile water for cleaning, during the stirring process, the connection mode of the second paddle 930 with the first rod 911 is adjusted according to the position of the second paddle 930, so that the mixture is uniformly mixed, the pouring rod 300 is switched in sequence according to the order of "from deep to shallow" during grouting, and the whole crack repair is completed.
