Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.
Unless defined otherwise, technical or scientific terms used in this disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The terms "first," "second," and the like, as used in this disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are meant to encompass the elements or items listed thereafter and equivalents thereof without materially departing from the other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
As described above, in the case of performing a deep water crack repairing operation, the transfer pipe used for transferring the slurry from the land to the deep water is long, the external water pressure of the transfer pipe is high, and the transfer pipe is easily crushed, so that the risk of clogging is likely to occur, and the time from mixing and stirring to injecting the slurry into the crack is long, and the slurry having a short setting time cannot be selected. Therefore, the selection of the sizing agent is limited, various adverse phenomena are easy to occur in the repairing process, and the grouting and repairing efficiency is reduced.
At least one embodiment of the present disclosure provides an underwater agitation grouting system and an underwater agitation grouting method. The underwater stirring grouting system comprises stirring grouting equipment and a multi-component material bag, wherein the stirring grouting equipment comprises a stirring cabin, and the stirring cabin is provided with a discharge opening; the multi-component material bag comprises a containing body, wherein the containing body comprises a discharge hole and a plurality of containing cavities, and the containing cavities are separated by a spacer; wherein, the stirring cabin can hold multicomponent material package, and the intensity of the holding body of multicomponent material package is greater than the intensity of spacer.
The underwater stirring grouting system provided by the embodiment of the disclosure can directly realize the procedures of mixing, stirring, grouting and the like of multi-component slurry under water, so that the time from mixing, stirring to crack injection of the slurry is shortened, and the selection range of the slurry is widened; moreover, the underwater stirring grouting system can directly stir, slurry and the like at the position where the crack needs to be repaired, so that a longer conveying pipeline is avoided, the grouting and repairing flow is simplified, the grouting and repairing difficulty is reduced, and the grouting and repairing efficiency is improved.
The underwater agitation grouting system and the underwater agitation grouting method of the present disclosure are described below by way of several specific examples.
At least one embodiment of the present disclosure provides an underwater agitation grouting system, and fig. 1 shows a schematic perspective view of the underwater agitation grouting system; FIG. 2 shows a schematic structural view of a multicomponent cartridge; FIG. 3 is a schematic diagram showing the front view of the underwater agitation grouting system; FIG. 4 shows a schematic cross-sectional view of the underwater agitation grouting system in FIG. 3 along the line A-A; and FIG. 5 shows another schematic cross-sectional structure of the underwater agitation grouting system.
As shown in fig. 1-5, the underwater agitation grouting system includes an agitation grouting apparatus 101 and a multicomponent bale 200. The stirring grouting device 100 includes a stirring tank 101 for mixing and stirring a plurality of grouting materials. The stirring tank 101 has a discharge opening 101A so that a plurality of grouting materials uniformly stirred in the stirring tank 101 can be discharged from the discharge opening 101A.
For example, the multicomponent cartridge 200 includes a housing 201, which may be, for example, a bag, and the housing 201 includes a discharge port 201A and a plurality of receiving chambers 202, and the plurality of receiving chambers 202 may be respectively configured to receive different grouting materials. For example, the plurality of receiving chambers 202 are separated by a spacer 203, and the outlet 201A may be located in one of the plurality of receiving chambers 202. For example, each of the accommodating chambers 202 is surrounded by the accommodating body 201 and the spacers 203, whereby the plurality of accommodating chambers 202 are independent from each other, so that contact of different grouting materials accommodated in the plurality of accommodating chambers 202 can be avoided. For example, the number of receiving cavities 202 may be two, three, four, etc., and embodiments of the present disclosure are not particularly limited thereto.
For example, the pod 101 may house a multi-component package 200, with the strength of the containment body 201 of the multi-component package 200 being greater than the strength of the spacer 203. Thus, when the multicomponent packet 200 is used, different grouting materials contained in the plurality of containing chambers 202 can be mixed by breaking the spacers 203 in the multicomponent packet 200, and at this time, since the strength of the containing body 201 is greater than that of the spacers 203, the containing body 201 can not be broken, so that the grouting materials do not contaminate the inner space of the stirring tank 101, and cleaning is not required after the completion of the work of the stirring tank 101.
For example, in some embodiments, the multicomponent package 200 is a disposable multicomponent package, so that when the underwater agitation grouting system is used for multiple agitation and grouting operations, only the multicomponent package needs to be replaced, and no additional procedures such as cleaning the agitation chamber are required.
For example, in some embodiments, the material of the housing 201 comprises polyvinyl chloride, such as a polyvinyl chloride film, in which case the material of the spacer 203 may also comprise polyvinyl chloride, such as a polyvinyl chloride film. For example, the thickness of the polyvinyl chloride film of the spacer 203 is smaller than that of the polyvinyl chloride film of the accommodating body 201, so that the spacer 203 has lower strength and is easily damaged by external force, while the accommodating body 201 has higher strength and is not easily damaged by external force.
Alternatively, in other embodiments, the spacer 203 may include a sealant, and in this case, a partial region of the inside of the accommodating body 201 may be bonded with the sealant, thereby forming a plurality of accommodating chambers 202 independent of each other. For example, the sealant may include a glue having a certain adhesiveness such as a hot melt adhesive. The sealant can form a seal with lower strength in the accommodating body 201, and is easily damaged by a certain external force.
For example, when the sealant is a hot melt adhesive, the hot melt adhesive may be coated on the accommodating body 201 where the spacer 203 needs to be formed in the process of preparing the multi-component package 200, and then the spacer 203 is formed after the hot melt is completed at a certain temperature, at this time, the strength of the spacer 203 can isolate different slurries under static state, but the spacer 203 can be damaged under a certain external force, so that the different slurries are mixed together.
For example, in some embodiments, the spacer 203 may include a diaphragm and a joint portion, such as a sealant, that adheres the diaphragm to the accommodating body 201, in which case the strength of the diaphragm may be the same as that of the accommodating body 201, and the joint portion may have a low strength, such as lower than that of the accommodating body 201, so as to be easily broken by a certain external force. At this time, at least part of the strength of the spacer 203 is lower than that of the accommodating body 201. For example, the sealant in this embodiment may be a hot melt adhesive or other acrylic glue, or the like.
For example, in some embodiments, the multi-component packages 200 may be pre-formed, i.e., finished packages are custom made, as described above, and each multi-component package 200 is a disposable multi-component package, e.g., multiple multi-component packages 200 may be ready for use and replacement in the blender compartment 101.
For example, in some embodiments, as shown in fig. 1, the underwater agitation grouting system further includes a discharge pipe 102 and a pipe clamp 103, where the discharge pipe 102 is configured to be connected to a discharge port 201A of the accommodating body 201 through a discharge opening 101A of the agitation chamber 101, and the pipe clamp 103 is disposed on the discharge pipe 102 and configured to open or close the discharge pipe 102, for example, to close the discharge pipe 102 when the agitation chamber 101 performs an agitation operation so as to prevent slurry in the accommodating body 201 from flowing out, and to open the discharge pipe 102 when the grouting operation is required after the agitation chamber 101 completes, so as to facilitate slurry in the accommodating body 201 from flowing out. For example, in some examples, the discharge tube 102 may be a polyvinyl chloride discharge tube. For example, the discharge tube 102 may be disposable, thereby avoiding the need for cleaning the discharge tube.
For example, in some embodiments, as shown in fig. 1, the underwater agitation grouting system further comprises an agitation tank drive apparatus 104, the agitation tank drive apparatus 104 being configured to drive the agitation tank 101 to rotate, thereby uniformly mixing the plurality of grouting materials in the multicomponent bale 200 within the agitation tank 101. For example, the stirring cabin 101 is cylindrical as a whole, and the stirring cabin driving device 104 can drive the stirring cabin 101 to rotate around a cylindrical central shaft as an axis, so that the multi-component material package 200 in the stirring cabin 101 can be subjected to stable acting force in the rotating process of the stirring cabin 101, and the accommodating body 201 is prevented from being damaged in the rotating process of the stirring cabin 101.
For example, in some examples, the pod drive 104 may include a hydraulic motor or a waterproof motor, etc., so long as the rotation of the pod 101 may be achieved, embodiments of the present disclosure are not limited to a specific form of the pod drive 104.
For example, in some embodiments, as shown in fig. 5, the underwater agitation grouting system may further include a rotary seal S to which the discharge port 201A of the housing body 201 and the discharge pipe 102 are respectively connected such that the discharge pipe 102 is rotatably connected with the discharge port 201A. Thereby, the discharge pipe 102 is prevented from being knotted during the rotation of the stirring chamber 101, and thus the extended state of the discharge pipe 102 is maintained.
For example, in some examples, as shown in fig. 5, the rotary seal S may include a first spacer S1 and a second spacer S2 rotatably and sealingly connected to each other, and the discharge port 201A of the housing body 201 and the discharge tube 102 are connected to the first spacer S1 and the second spacer S2 of the rotary seal S, respectively, so that the rotational connection of the discharge tube 102 and the discharge port 201A is achieved. For example, the rotary seal S may be a composite rotary seal including an outer ring (as the second spacer S2) formed of, for example, polytetrafluoroethylene (PTFE) and an O-ring (as the first spacer S1) formed of, for example, nitrile rubber (NBR). The O-ring may act to support the outer ring, making the entire rotary seal easier to install.
For example, in some embodiments, as shown in fig. 1, the underwater mixing grouting system may further include a piston 105, where the piston 105 is disposed in the mixing chamber 101 and opposite to the discharge opening 101A of the mixing chamber 101, and where the piston 105 is configured to push the multicomponent packet 200 toward the discharge opening 101A in a state where the mixing chamber 101 accommodates the multicomponent packet 200, thereby achieving the effect of extruding the multicomponent packet 200. For example, squeezing the multicomponent packet 200 may effect destruction of the spacers 203 in the multicomponent packet 200, thereby mixing the various grouting materials in the plurality of receiving chambers 202 in the multicomponent packet 200, and in addition, squeezing the multicomponent packet 200 may promote flow of slurry from the discharge port 201A of the container 201 to be delivered to a desired location through the discharge pipe 102 during grouting.
For example, in some embodiments, as shown in fig. 4, the underwater mixing grouting system may further include a piston drive 106, the piston drive 106 configured to drive the piston 105 to reciprocate. For example, when the piston 105 is not required to press the multicomponent cartridge 200, such as during a stirring operation of the stirring chamber 101, the piston drive 106 is configured to drive the piston 105 to an end of the stirring chamber 101 remote from the discharge opening 101A, and when the piston 105 is required to press the multicomponent cartridge 200, the piston drive 106 is configured to drive the piston 105 to move in a direction toward the discharge opening 101A to press the multicomponent cartridge 200.
For example, in some examples, piston drive 106 may include a high pressure water pump, a telescoping hydraulic cylinder, or a telescoping electric cylinder, among other drive components. For example, as shown in fig. 4, in the case where the piston driving device 106 includes a high-pressure water pump 1062, the piston driving device 106 further includes auxiliary components such as a liquid storage device 1061 and an infusion tube 1063 (e.g., a high-pressure water tube), the liquid storage device 1061 is used to store a liquid, such as water, used for driving the piston 105, and the high-pressure water pump 1062 may apply high-pressure water to the piston 105 through the infusion tube 1063 by using the liquid stored in the liquid storage device 1061 to achieve a driving action on the piston 105 by water pressure. For example, in other examples, where the piston drive 106 includes a telescoping hydraulic cylinder or telescoping electric cylinder, the telescoping hydraulic cylinder or telescoping electric cylinder may include a telescoping rod that may be driven, which may enable driving of the piston 105.
For example, in some embodiments, as shown in FIG. 1, the subsea mixing grouting system can further comprise a tilt drive 107, the tilt drive 107 configured to drive the mixing chamber 101 to tilt. For example, during grouting, the tilting drive 107 is configured to drive the agitator tank 101 to tilt, at which point the discharge opening 101A of the agitator tank 101 is at a lower elevation, so that the flow of slurry from the discharge opening 201A of the container 201 can be encouraged by gravity, and then conveyed to a desired location through the discharge pipe 102. For example, in some examples, the tilt drive 107 may include a tilt cylinder, hydraulically or electrically driven.
For example, in some embodiments, as shown in FIG. 1, the underwater agitation grouting system may further include a base 108, and the underwater agitation grouting system may be secured in a desired position in the water by the base 108. For example, an underwater agitation grouting system may be brought to a desired location in the water by a manual or underwater robot.
Embodiments of the present disclosure provide underwater mixing grouting systems that can operate at depths of hundreds of meters (e.g., 300 meters-1000 meters) underwater, such as crack repair operations. When working under water, through a series of actions such as extrusion of the piston, underwater stirring, underwater grouting and the like, the time from slurry mixing to grouting completion is shortened, so that slurry with short solidification time can be selected, the selection range of the slurry is widened, a longer conveying pipeline can be avoided, and pipeline materials are saved. Through testing, when the underwater stirring grouting system provided by the embodiment of the disclosure is used for grouting operation, the time from slurry mixing to grouting completion can be within about 1 minute, so that the operation time is greatly shortened, and the operation efficiency is improved.
At least one embodiment of the present disclosure further provides a method for underwater agitation grouting using the above-mentioned underwater agitation grouting system, as shown in fig. 6, the method includes steps S101 to S107.
Step S101: and respectively placing a plurality of grouting materials into a plurality of accommodating cavities of the multi-component material packet.
For example, the plurality of grouting materials include two or more different grouting materials, and the plurality of grouting materials are respectively placed in the plurality of accommodating cavities 202 of the multi-component package 200 to avoid the plurality of grouting materials from contacting.
Step S102: and placing the multi-component material bags into a stirring cabin of stirring grouting equipment.
For example, after the plurality of grouting materials are respectively placed in the plurality of receiving cavities 202 of the multi-component package 200, the multi-component package 200 is placed in the stirring tank 101 of the stirring grouting apparatus so as to be mixed and stirred by using the stirring tank 101 later.
Step S103: the discharge port of the multi-component material bag is connected to the discharge pipe through the discharge opening.
For example, the outlet port 201A of the multicomponent cartridge 200 is connected to the discharge tube 102 through the outlet opening 101A of the agitator tank 101 using a rotary seal S such that the outlet port 201A is rotationally sealed from the discharge tube 102. Accordingly, when the stirring chamber 101 is rotated to stir a plurality of grouting materials, the discharge pipe 102 is always maintained in an extended state, and no adverse phenomena such as rotation and knotting occur. After being uniformly stirred, the various grouting materials can be sequentially conveyed to a required position through the discharge port 201A and the discharge pipe 102.
For example, in some embodiments, steps S101-S103 may be performed on land, thereby saving underwater operation time. For example, the order of steps S101 to S103 may be interchanged, for example, step S102 may be performed first, then step S101 may be performed, or step S103 may be performed first, then step S102 may be performed, etc., and the order of performing the steps is not limited in the embodiments of the present disclosure.
Step S104: the stirring grouting equipment is transported to an underwater working place.
For example, the stirring grouting device can be transported to an underwater work site by means of a manual or underwater robot or the like.
Step S105: the spacers between the plurality of receiving cavities are broken to mix the plurality of grouting materials.
For example, in some embodiments, the agitator tank may be driven to rotate such that the spacers 203 between the plurality of receiving cavities 202 are broken, at which time the receiving body 201 is not broken because the strength of the receiving body 201 is stronger relative to the spacers 203.
For example, in some embodiments, where the stirring grouting device further includes a piston 105 disposed in the stirring tank 101, the manner in which the piston 105 is driven to press the multicomponent cartridge 200 may also be adopted such that the spacers 203 between the plurality of accommodating chambers 202 are broken, and the accommodating body 201 is not broken in the process. For example, a high-pressure water pump, a telescopic hydraulic cylinder, a telescopic electric cylinder or the like can be adopted to drive the piston 105 to reciprocate in the stirring tank 101, so as to achieve the purpose of extruding the multi-component material package 200.
For example, the discharge pipe 102 is provided with a pipe clamp 103, and before grouting, the pipe clamp 103 clamps the discharge pipe 102 all the time so that the discharge pipe 102 is closed and no slurry is discharged. Also, as the discharge tube 102 closes, the piston 105 will experience a greater resistance to a degree of compression of the multicomponent cartridge 200 and will not advance.
Step S106: and driving the stirring cabin to stir.
For example, the stirring tank 101 is driven to rotate by the stirring tank driving device 104, so that stirring is performed. For example, during the stirring operation of the stirring tank 101, the discharge pipe 102 is always clamped by the pipe clamp 102 to avoid discharge of slurry.
Step S107: the mixture of the plurality of grouting materials is driven to be discharged from the discharge pipe.
For example, after the stirring operation of the stirring chamber 101 is completed, the pipe clamp 102 may be opened, and the pipe clamp 103 may be released from the discharge pipe 102 to drive the mixture of the plurality of grouting materials to be discharged from the discharge pipe 102.
For example, in some embodiments, the piston 105 may be driven to push the multicomponent cartridge 200 in the direction of the discharge opening 101A to facilitate the flow of a mixture of multiple grouting materials from the discharge opening 201A.
For example, in some embodiments, the mixing and grouting apparatus further includes a tilt drive 107, such as a tilt cylinder, where the tilt drive 107 may be used to drive tilting of the stir chamber to facilitate the flow of a mixture of grouting materials from the outlet 201A.
For example, the opening of the discharge pipe 102 opposite to the discharge port 201A may be directed toward the underwater crack for grouting, repairing, etc. the length of the discharge pipe 102 may be relatively short since the entire stirring grouting device may be located at the repair work site.
For example, in some embodiments, steps S105-S107 may be performed in water. For example, the order of the steps S105 and S106 may be exchanged with each other or may be performed simultaneously, and the order of performing the steps is not limited in the embodiments of the present disclosure.
The underwater stirring grouting method provided by the embodiment of the disclosure can realize stirring grouting work, such as crack repair work, at a depth of hundreds of meters (300 meters-1000 meters, for example) under water. When working under water, through a series of actions such as extrusion of the piston, underwater stirring, underwater grouting and the like, the time from slurry mixing to grouting completion is shortened, so that slurry with short solidification time can be selected, the selection range of the slurry is widened, a longer conveying pipeline can be avoided, and pipeline materials are saved. Through tests, when grouting operation is performed by using the underwater stirring grouting method provided by the embodiment of the disclosure, the time from slurry mixing to grouting completion can be within about 1 minute, so that the operation time is greatly shortened, and the operation efficiency is improved.
