Description

Technical Field

[0001] The present invention relates to the technical field of safe mining of coal mines, and in particular to a casting mold for a brittle model including a fault and a tunnel, and a casting method for the model. Background Art

[0002] Similarity simulation testing is an important method for studying geotechnical engineering problems. Compared with theoretical analysis and numerical simulation, it has advantages such as intuitiveness, strong feasibility, and high convincingness. However, the preparation of similarity models is both the key and the difficulty of similarity simulation testing. Conducting similarity simulation testing of fault-slip rock bursts in coal mine roadways requires the preparation of a large-scale brittle similarity model that includes both the fault and roadway structures.

[0003] Currently, similarity simulation tests primarily use traditional materials such as gypsum, calcium carbonate, sand, cement, and water mixed in a specific proportion to form a solid mortar. This mortar is then laid layer by layer and vibrated to form a similar model. However, these similar models typically lack brittle mechanical properties. As the model size increases, the vibration effect deteriorates, making it difficult to ensure model homogeneity, severely impacting test results. Furthermore, for large similar models, the layer-by-layer solid mortar laying process makes it difficult to produce fine fault structures. Summary of the Invention

[0044] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0045] In the description of the embodiments of the present invention, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0046] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on the specific circumstances.

[0047] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0048] The following combination Figure 1 and Figure 2 A mold for casting a brittle model containing faults and tunnels, provided in an embodiment of the present invention, comprises a mold box 1 and auxiliary structures. The mold box 1 has a box-like structure and includes a bottom plate 11 and multiple side plates. The auxiliary structures include a fault partition plate 21, a first separation plate, and a second separation plate.

[0049] Among them, the first separation plate and the second separation plate are spliced ​​together, and the first separation plate and the second separation plate are both arranged on the bottom plate 11. In order to facilitate drainage, a drainage groove is provided on the first separation plate or the second separation plate, or a drainage groove is provided on the first separation plate and the second separation plate. A plurality of side plates are spliced ​​together on the first separation plate and the second separation plate, and a plurality of side plates cooperate with the first separation plate and the second separation plate to construct a receiving cavity. The fault partition 21 is arranged in the receiving cavity, and the fault partition 21 is connected to at least one of the side plates. The fault partition 21 divides the receiving cavity into a first receiving cavity and a second receiving cavity for loading slurry, so that after pouring, a casting model containing a fault structure can be constructed.

[0050] During the casting process of the model, the first separation plate and the second separation plate are first set on the base plate 11, and at least one side plate is connected to the fault partition plate 21 and set on the first separation plate and the second separation plate; the remaining side plates are set on the first separation plate and the second separation plate, and the first and second accommodating cavities for loading slurry are constructed in conjunction with the fault partition plate 21.

[0051] After the main structure of the brittle model casting mold including the fault and the tunnel is installed, the brittle model casting mold including the fault and the tunnel is hoisted into a water tank to facilitate the processing of a large amount of water precipitated during the model forming process.

[0052] At the same time, in order to ensure the flatness of the casting model, a spirit level can be placed on the base plate 11 to check the levelness of the base plate 11 by adjusting the height of the leveling shims around the bottom.

[0053] After setting up the mold for the brittle model containing the fault and the roadway, casting is performed in the first and second accommodating chambers. The slurry can be drained using a drainage trough, and then poured into the first and second accommodating chambers. After casting, the mold for the brittle model containing the fault and the roadway is dismantled. The first or second separation plate is moved, the side plate is moved and then lifted away, and the first or second separation plate is moved. The fault partition 21 is removed from the casting mold to construct a casting model containing the fault structure.

[0054] The mold for casting a brittle model containing faults and tunnels, provided in an embodiment of the present invention, comprises a first and second separating plate disposed on a base plate 11, drainage grooves disposed on the first and / or second separating plates, and a fault partition 21 separating the accommodating chamber into a first and second accommodating chamber for loading slurry. This allows for the formation of a casting model containing faults during casting, and the drainage grooves allow for easy removal of the fault partition 21, thus resolving the difficulty in producing fine fault structures using a layer-by-layer solid mortar laying process.

[0055] It should be noted that the first and second separation plates are composed of two 1mm thick steel plates. They are the same size as the base plate 11 and have bolt holes that correspond exactly to the base plate 11. They are also surrounded by approximately 2mm wide drainage grooves. The first and second separation plates serve two purposes: first, they allow for drainage; second, they allow for the separation of the two halves of the cast model by pulling them laterally, facilitating the removal of the fault diaphragm 21.

[0056] In one example, if Figure 1 and Figure 2 As shown, the plurality of side panels include two first side panels 12 and two second side panels 13 .

[0057] The two first side panels 12 are long side panels, and are positioned opposite each other on the top surfaces of the first and second separation panels. The two second side panels 13 are short side panels, and are positioned opposite each other on the other two sides of the top surfaces of the first and second separation panels. For example, the two first side panels 12 are positioned on the front and rear sides of the top surfaces of the first and second separation panels, and the two second side panels 13 are positioned on the left and right sides of the top surfaces of the first and second separation panels. The two first side panels 12 and the two second side panels 13 are spliced ​​onto the first and second separation panels to form a receiving cavity.

[0058] In one embodiment, the mold box 1 is a rectangular parallelepiped with dimensions of 0.85m×0.85m×1.60m, the two first side panels 12 are long side panels, the two second side panels 13 are short side panels, and the bottom plate 11 is connected to the two first side panels 12 and the two second side panels 13 by bolts. Since the first separation plate and the second separation plate are arranged on the bottom plate 11, the corresponding bolts pass through the first separation plate or the second separation plate and are arranged in the bottom plate 11, thereby fixing the two first side panels 12 and the two second side panels 13 to the bottom plate 11, the first separation plate and the second separation plate to form a receiving cavity for loading slurry.

[0059] In addition, the mold box 1 may also be provided with a top plate 14 , which is correspondingly provided above the bottom plate 11 , and is used to seal the entire accommodating cavity.

[0060] In this embodiment, there are small holes with a diameter of 2 mm at the corresponding positions of the fault partition 21 and the first side plate 12. The fault partition 21 and the two first side plates 12 are fixed to the two first side plates 12 by iron wire. The two first side plates 12 and the two second side plates 13 are equipped with chamfering devices with a right-angle side length of 5 cm at the bottom of the four sides, which is convenient for the later large model to be lifted, transported and installed through the support frame relying on the chamfers on all sides.

[0061] In order to construct the roadway in the brittle model casting mold containing faults and roadways, Figure 3 As shown, the auxiliary structure further includes: a tunnel model 22. The tunnel model 22 is a rectangular parallelepiped with a size of 0.15m×0.15m×1.20m.

[0062] like Figure 1 and Figure 2 As shown, the two first side panels 12 are provided with opposing mounting holes 120, and the roadway model 22 is disposed in the accommodating cavity. The two ends of the roadway model 22 are inserted into the two opposing mounting holes 120, and the roadway model 22 runs through the entire mold box. Thus, after casting, a roadway can be constructed in the casting mold.

[0063] The tunnel model 22 includes a plurality of third side panels 220. These panels 220 are joined together to form a hollow tunnel cavity. In this embodiment, the tunnel model 22 is composed of four steel plates, which are connected internally by shims with screw holes and bolts.

[0064] Based on the above embodiment, in one embodiment, a drain plug is provided in the drain groove, and the opening and closing of the drain can be controlled by removing and installing the drain plug.

[0065] Before pouring, cut a thin wire longer than the gutter length and insert it into the gutter as a blocking wire to prevent slurry from invading and clogging the gutter. Ensure that each gutter is equipped with a blocking wire. After pouring, if water seeps out of the base plate 11, use pliers to pull out the blocking wire from the gutter (to reduce the difficulty of pulling out the blocking wire, pull it out earlier) to increase the drainage channel.

[0066] The present invention also proposes a method for casting a model using the above-mentioned brittle model casting mold containing faults and lanes. The structure of the brittle model casting mold containing faults and lanes is as follows: Figures 1 to 3 shown.

[0067] The method of casting the model is as follows Figure 4 As shown, the following steps are included:

[0068] Step S401: a first separation plate and a second separation plate are arranged on the bottom plate, and at least one side plate is connected to the fault diaphragm and arranged on the first separation plate and the second separation plate.

[0069] Find a level ground, place the water tank, use a gantry crane to lift the base plate into the water tank, place a spirit level on the base plate, and adjust the leveling shims at the four corners of the base plate to keep the base plate level.

[0070] After the bottom plate is set, a first separation plate and a second separation plate are set on the bottom plate, and at least one side plate is connected to the fault partition and set on the first separation plate and the second separation plate.

[0071] Step S402: The remaining side plates are arranged on the first separation plate and the second separation plate, and cooperate with the fault partition plate to construct a first accommodating cavity and a second accommodating cavity for loading slurry.

[0072] After the fault partition is set, the remaining side plates are set on the first separation plate and the second separation plate to form a receiving cavity, and at the same time, the fault partition is used to construct the first receiving cavity and the second receiving cavity for loading slurry.

[0073] Step S403: Casting is performed in the first accommodating cavity and the second accommodating cavity.

[0074] After the construction of the casting mold of the brittle model including the fault and the tunnel is completed, casting is carried out in the first accommodating cavity and the second accommodating cavity, and drainage can be achieved by using the drainage trough.

[0075] Step S404: demoulding the casting mold of the brittle model including the fault and the tunnel after casting, so as to construct a casting model including the fault structure.

[0076] After the casting model is cured for a preset time, for example, three days later, the casting mold of the brittle model including the fault and the tunnel can be demolded, the first separation plate or the second separation plate can be moved, the side plate can be moved and lifted away, the first separation plate or the second separation plate can be moved, and the fault partition 21 can be removed from the casting model to construct a casting model including the fault structure.

[0077] The casting model method provided by the embodiments of the present invention comprises disposing a first and second separating plate on a base plate 11, providing drainage grooves on the first and / or second separating plates, and utilizing a fault partition 21 to separate the accommodating chamber into a first and second accommodating chamber for loading slurry. This allows for the formation of a casting model containing faults during casting, and the drainage grooves allow for easy removal of the fault partition 21, thus resolving the difficulty of producing fine fault structures using a layer-by-layer solid mortar laying process.

[0078] Based on the above embodiments, in one embodiment, Figure 5 As shown, the steps of pouring in the first accommodating cavity and the second accommodating cavity include:

[0079] Step S501: introducing raw materials into a mixing barrel and stirring them in the mixing barrel.

[0080] In this embodiment, the raw materials include: solid material and liquid material; the solid material includes: aggregate talc powder and curing agent sodium fluorosilicate; the liquid material includes: binder water glass.

[0081] Specifically, the raw materials are divided into solid materials and liquid materials. The solid materials include talc powder as aggregate and sodium fluorosilicate as curing agent, and the liquid material is water glass as binder, with the mass proportions being 20.8%, 9.7%, and 69.5%, respectively. The weight of each barrel of material is calculated based on the volume of the mixing barrel (200L) and the volume of the model. According to experience, each barrel requires 260kg of water glass, 60kg of talc powder, and 28kg of sodium fluorosilicate, a total of 7 barrels are required. After the pouring is completed, there will still be a certain amount of material redundancy.

[0082] Because pouring requires continuous operation, all seven barrels of material must be prepared before pouring. Water glass should be extracted using an electric pump and weighed using an electronic scale. Talcum powder should be weighed directly using an electronic scale. Because sodium fluorosilicate easily hardens when exposed to moisture, it should be screened using an electric sieve before weighing, and then weighed using an electronic scale. It is important to note that sodium fluorosilicate is somewhat toxic, so you should wear a mask and eye protection during weighing, and use clothing to protect yourself. After weighing, clean yourself immediately. After weighing, place the seven barrels of material according to their composition near the mixing drum for quick and easy loading.

[0083] Step S502: After the raw materials are evenly stirred, the raw materials are introduced into the first accommodating cavity and the second accommodating cavity for pouring.

[0084] After the materials are mixed, they become slurry and must be stirred with a mixing barrel to ensure uniform mixing. For example, two electric mixing barrels with a volume of 200L can be set up, and a reasonable speed can be set to ensure the stirring effect while controlling the slurry from splashing. Since the slurry has the characteristics of rapid setting, especially under high temperature conditions (above 30°C), the slurry solidifies very quickly, so two mixing barrels are required to work in parallel. After the raw materials are evenly stirred, they are introduced into the first and second accommodating chambers for pouring. When pouring, pour all the way to the top surface of the mold so that the slurry is slightly higher than the side plate, and then use a long steel ruler to scrape the top surface of the model flat to complete the model pouring.

[0085] Step S503: After pouring is completed, the mixing barrel is cleaned with clean water.

[0086] Before pouring the model, prepare two large buckets of clean water. After pouring the model, drain any excess slurry from the mixing bucket. Then, use an electric pump to pump clean water into the mixing bucket, stirring continuously, and clean the mixing bucket. After draining the clean water, use a high-pressure water gun to remove any consolidation residue from the mixing bucket. The mixing bucket must be cleaned immediately after pouring to prevent the slurry from consolidating inside.

[0087] Based on the above embodiments, in one embodiment, the steps of demolding the casting mold of the brittle model containing the fault and the tunnel after casting to construct a casting model containing the fault structure include: moving the second side plate horizontally and lifting it away; decomposing the tunnel model into multiple third side plates and moving them out one by one; moving the first side plate horizontally and lifting it away; moving the first separation plate or the second separation plate to remove the fault partition from the casting model to construct a casting model containing the fault structure.

[0088] Specifically, about 2 to 3 hours after the pouring is completed, the casting model begins to release water, and water seepage can be found on the bottom plate. At this time, use pliers to pull out the drainage plugging wire (to reduce the difficulty of pulling out the drainage plugging wire, the time of pulling out the drainage plugging wire can be advanced) to increase the drainage channel.

[0089] After the pouring model is maintained for three days, the mold can be removed. The second side plate is removed first. After the bolts are removed, the gantry crane is used to pull the second side plate tightly without lifting it. The second side plate is moved horizontally outward, and then the second side plate is lifted away. It is strictly forbidden to directly lift the second side plate, otherwise the chamfer structure at the bottom of the second side plate will cause damage to the pouring model.

[0090] The prefabricated roadway is removed. The bolts in the prefabricated roadway are removed first, so that the prefabricated roadway is disassembled into four independent third side plates. The third side plates are pulled out in turn using a chain hoist. During the pulling-out process, it is necessary to ensure that the pulling-out direction of the chain hoist is straight with the third side plate. The third side plate is relatively long. If the pulling-out direction is not straight with the third side plate, it is easy to form a card and cause the third side plate to be difficult to pull out.

[0091] The first side plate is removed. After the bolts are removed, the gantry crane is used to pull the first side plate tightly without lifting it. The first side plate is moved horizontally outward, and then the first side plate is lifted away. It is strictly forbidden to directly lift the first side plate, otherwise the chamfer structure at the bottom of the first side plate will cause damage to the pouring model.

[0092] Then the first separation plate or the second separation plate is moved, and the fault partition plate is taken out of the pouring model to construct a pouring model containing a fault structure. Finally, the pouring model is cleaned and polished in time.

[0093] Based on the above embodiment, in one embodiment, the step of connecting at least one side plate with the fault partition plate and arranging the at least one side plate on the first separation plate and the second separation plate; arranging the remaining side plates on the first separation plate and the second separation plate to cooperate with the fault partition plate to construct the first accommodating cavity and the second accommodating cavity for loading the slurry includes: connecting two first side plates with the fault partition plate, and arranging the two first side plates and the fault partition plate on the first separation plate and the second separation plate. The roadway model is arranged in the mounting holes of the two first side plates, and two second side plates are arranged on the first separation plate and the second separation plate. The fault partition plate, the two first side plates, the two second side plates, the first separation plate and the second separation plate constitute the first accommodating cavity and the second accommodating cavity for loading the slurry.

[0094] Specifically, according to the design fault position, the fault size is calculated. According to the rough fault of through type, the fault partition plate (sawtooth partition plate) with a thickness of about 2mm is used. Because the model has the characteristics of water shrinkage and the water deformation is large at the air contact position, in order to prevent the fault gap width difference from being large, the top of the fault partition plate is reduced by 1cm compared with the side in calculating the fault size, and the bottom of the fault partition plate can be directly contacted with the mold bottom plate without reducing the size. According to the calculated fault partition plate size, the angle grinder is used to cut the fault partition plate to the size. According to the preset position, the thin iron wire is used to pass through the mounting holes on the two first side plates and the fault partition plate, and the iron wire is tightened outside the two first side plates, and the fault partition plate is fixed firmly by drilling and tightening one by one. And the two second side plates are arranged on the first and second separation plates, and the fault partition plate, the two first side plates, the two second side plates, the first separation plate and the second separation plate constitute the first and second accommodation cavities for loading slurry.

[0095] In a specific embodiment, the pouring process of the pouring model comprising the fault structure comprises the following steps:

[0096] (1) Bottom plate leveling: find a horizontal ground, place a water tank, use a gantry crane to hoist the bottom plate into the water tank, place a level on the bottom plate, adjust the leveling pads at the four corners of the bottom plate to keep the bottom plate level.

[0097] (2) Place the separation plate: the flat plate composed of the first and second separation plates is consistent in size with the mold bottom plate, use a small iron hammer to tap around to make the bolt holes on the first and second separation plates completely correspond to the mold bottom plate.

[0098] (3) Install the first side plate: install two long side plates on the first and second separation plates, tighten with bolts to fix firmly, and make sure that each bolt hole is installed with a bolt and pre-tightened. The first side plate has a chamfer structure at the bottom, pay attention to clean the solid residues inside and outside the chamfer structure to avoid misalignment.

[0099] (4) Fault partition plate installation: according to the design fault position, the fault size is calculated. According to the rough fault of through type, the fault partition plate (sawtooth partition plate) with a thickness of about 2mm is used. Because the model has the characteristics of water shrinkage and the water deformation is large at the air contact position, in order to prevent the fault gap width difference from being large, the top of the fault partition plate is reduced by 1cm compared with the side in calculating the fault size, and the bottom of the fault partition plate can be directly contacted with the mold bottom plate without reducing the size. According to the calculated fault partition plate size, the angle grinder is used to cut the fault partition plate to the size. According to the preset position, the thin iron wire is used to pass through the mounting holes on the two first side plates and the fault partition plate, and the iron wire is tightened outside the two first side plates, and the fault partition plate is fixed firmly by drilling and tightening one by one.

[0100] (5) Installing the prefabricated modular roadway model: The roadway model is assembled and consists of four third side panels connected by internal bolts. Before connection, each third side panel needs to be cleaned with a polishing machine, and the contact surfaces between adjacent third side panels need to be greased to increase lubrication and reduce the difficulty of disassembly. After completing the above treatment, the four third side panels are spliced ​​together to form the roadway model.

[0101] (6) Applying butter: Before installing the second side plate, use a roller brush to apply butter evenly and in a thin layer on the bottom plate, separator plate, inner wall of the first side plate, fault partition and the surface of the roadway model. The purpose of applying butter is to make the model easier to demold. Solid lubricants such as butter should be used. Liquid lubricants are not recommended to prevent them from being washed away by the slurry.

[0102] (7) Install the short side panel: Apply butter to the inner side of the second side panel, then use a gantry crane to hoist the second side panel onto the base plate, align the bottom and side bolt holes, install the bolts, and pre-tighten them. The bottom of the second side panel is also arranged with a chamfer structure. Before installing the second side panel, it is necessary to clean the solid residue inside and outside the chamfer structure to prevent loose connection. At this point, the brittle model casting mold containing the fault and the roadway is assembled.

[0103] (8) Install drainage plugging wires: There are multiple strip drainage grooves on the four sides of the separation plate to drain the water from the model. Before pouring, cut a thin iron wire longer than the length of the drainage groove (the diameter should be smaller than the width of the drainage groove) and insert it into the drainage groove as a drainage plugging wire to prevent the slurry from invading and clogging the drainage groove. Ensure that each drainage groove is installed with a drainage plugging wire.

[0104] (9) Material preparation: Solid materials include talc powder as aggregate and sodium fluorosilicate as curing agent, and liquid materials include water glass as binder, with the mass proportions of 20.8%, 9.7% and 69.5% respectively. The weight of each barrel of material is calculated based on the volume of the mixing barrel (200L) and the volume of the model. According to experience, each barrel requires 260kg of water glass, 60kg of talc powder and 28kg of sodium fluorosilicate, which is 7 barrels in total. There is still a certain amount of material redundancy after pouring. Since pouring requires continuous operation, all 7 barrels of material must be prepared before pouring. Water glass is extracted using an electric oil pump and weighed using an electronic scale. Talc is weighed directly using an electronic scale. Since sodium fluorosilicate is easy to harden when it gets damp, it needs to be screened using an electric sieve before weighing, and then weighed using an electronic scale. It should be noted that sodium fluorosilicate is toxic to a certain extent. When weighing, you need to wear a mask and eye mask, and cover your body with clothes. After weighing, you should clean yourself in time. After the 7 barrels of materials are weighed, they are placed near the mixing barrel according to their combination for easy and quick loading.

[0105] (10) Model casting: After the materials are mixed, they become slurry, which must be stirred with a mixing bucket to mix evenly. For example, two electric mixing buckets with a volume of 200L can be set up, and a reasonable speed can be set to ensure the stirring effect and control the slurry from splashing. Since the slurry has the characteristics of rapid setting, especially under high temperature conditions (above 30°C), the slurry solidifies very quickly, so two mixing buckets are required to work in parallel. After the raw materials are evenly stirred, the raw materials are introduced into the first and second accommodating chambers for casting. When pouring, pour all the way to the top surface of the mold so that the slurry is slightly higher than the side plate, and then use a long steel ruler to scrape the top surface of the model flat to complete the model casting.

[0106] (11) Cleaning the mixing barrel: Before casting the model, prepare two large barrels of clean water. After the model is cast, drain the excess slurry in the mixing barrel in time, then use an electric oil pump to pump clean water into the mixing barrel, continue stirring, and clean the mixing barrel. After draining the clean water, use a high-pressure water gun to remove the solidified residue in the mixing barrel. The mixing barrel must be cleaned immediately after casting to prevent the slurry from solidifying in the mixing barrel.

[0107] (12) Model drainage and demolding: About 2 to 3 hours after the casting is completed, the casting model begins to release water, and water can be found seeping out from the bottom plate. At this time, use pliers to pull out the drainage plug (to reduce the difficulty of pulling out the drainage plug, the time of pulling out the drainage plug can be advanced) to increase the drainage channel. After the casting model has been cured for three days, the mold can be demolded. First, remove the second side plate of the mold. After removing the bolts, use the gantry crane to tighten the second side plate, but do not lift it up. Move the second side plate horizontally outward, and then lift the second side plate away. It is strictly forbidden to lift the second side plate directly, otherwise the chamfered structure at the bottom of the second side plate will cause damage to the casting model. To dismantle the precast tunnel, first remove the bolts within the precast tunnel, disintegrating it into four independent third side panels. Use the fall chain to pull out the third side panels one by one. During the pull-out process, ensure that the fall chain's pull-out direction is aligned with the third side panels. The third side panels are long, and if the pull-out direction is not aligned with the third side panels, it can easily become stuck, making it difficult to pull out. Next, remove the first side panel. After removing the bolts, use the gantry crane to tighten the first side panel without lifting it. Move the first side panel horizontally outward and then lift it away. Do not lift the first side panel directly, as this will damage the chamfered structure at the bottom of the first side panel. Then, move the first or second separation plate to remove the fault partition from the casting model, thus constructing a casting model that includes the fault structure. Finally, clean and polish the casting model promptly.
