Technical Field

[0001] The utility model relates to the field of kilometer-deep well wall concrete pouring, in particular to a kilometer-deep well pouring system. Background Art

[0002] In the process of developing deep underground mineral resources, shaft engineering is the throat engineering of the mine. Changes in every link in the process of shaft excavation have more or less impact on the quality and progress of the project. Due to the excessive pouring volume and long process time of large-section shaft during concrete pouring, many problems such as reduced work efficiency of personnel and abnormal operation of equipment have occurred. The traditional pouring method is to use a plant mixer + concrete ash tank, which has the disadvantages of long process time and high operating cost. It is also difficult to achieve parallel operation of the process, which makes the progress of the project unguaranteed.

[0003] In addition, when the concrete is lowered from the surface too quickly and the slump is too low, the friction between the concrete and the pipe wall will be too large. If you are not careful, the ash pipe will be blocked and the concrete impact will cause the ash pipe to fall. When using pipelines to transport concrete downward, there will also be a problem of fast exit speed due to the huge height difference. Utility Model Content

[0004] The technical problem to be solved by the utility model is how to pour a kilometer-deep well with a deep wellbore, a large cross-section and a large amount of concrete pouring at one time.

[0005] The utility model provides a technical solution to the above-mentioned technical problems as follows: a kilometer deep well pouring system, comprising at least one pouring group, each pouring group comprising an ash storage bucket, a flow control device, an ash chute, a deceleration device, a secondary stirring funnel and an ash separator, the ash storage bucket, the flow control device, the ash chute, the deceleration device, the secondary stirring funnel and the ash separator being arranged in sequence from top to bottom and connected.

[0006] The beneficial effects of the utility model are as follows: the ash storage bucket is used to store concrete, and the concrete is continuously released, so that the pouring process is continuous, the construction quality is guaranteed, and the untimely supply of concrete due to equipment failure is reduced, which forms construction joints and affects the appearance. Self-mixed concrete can be replaced with commercial concrete. The use of commercial concrete makes on-site civilized production more standardized and the concrete mix ratio more accurate.

[0007] A flow control device is installed at the upper end of the ash chute to control the concrete flow, reduce the concrete flow rate, guide the flowing concrete, and reduce the friction of aggregate on the pipeline. The flow controller is fully used to control the concrete flow and flow rate, which not only ensures the continuity of concrete lowering, but also reduces the probability of pipe blockage. To a certain extent, it reduces the risk of pipe blockage of the ash chute connected below the ash hopper, and ensures the safety of the pipeline in the wellbore.

[0008] A deceleration device is added at the lower end of the ash chute to reduce the direct impact of concrete on the pipe wall and further reduce the concrete speed.

[0009] The secondary mixing funnel mixes the concrete in the pipe again to ensure the workability of the concrete. The ash distributor disperses and pours the concrete to ensure the uniformity of pouring.

[0010] This solution uses pipelines to transport concrete, and the main and auxiliary winches can discharge slag and remove the slag in the well, which optimizes the construction process, reduces operating costs, improves construction efficiency, and reduces equipment investment and management costs. The flow control device and deceleration device control the concrete flow and flow rate to make the construction smoother.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the flow control device includes an ash hopper and a flow controller, the flow controller is installed in the ash hopper, the flow controller includes at least two diverter plates, the diverter plates are arranged along the radial direction of the ash hopper, at least two of the diverter plates are distributed at intervals along the circumference of the ash hopper, and at least two of the diverter plates are fixed to each other at one end facing the center of the ash hopper, and the lower end of the ash funnel is fixedly connected and communicated with the upper end of the ash pipe.

[0013] The beneficial effect of adopting the above further scheme is: placing the flow controller in the ash hopper and adjusting the position properly can control the concrete flow, reduce the concrete flow rate, guide the flowing concrete, and reduce the friction of aggregate on the pipeline. Fully applying the flow controller to control the concrete flow rate and flow rate can not only ensure the continuity of concrete lowering, but also reduce the probability of pipe blockage, and to a certain extent reduce the risk of pipe blockage of the ash hopper connected below the ash hopper, and ensure the safety of the pipeline in the wellbore.

[0014] Furthermore, each pouring group also includes a connecting pipe and a gate valve, one end of the connecting pipe is connected and communicated with the ash storage bucket outlet of the ash storage bucket, the other end of the connecting pipe is located above the ash hopper, and the gate valve is arranged at one end of the connecting pipe.

[0015] The beneficial effects of adopting the above further scheme are: using an ash storage bucket to store ash, and using a plug valve on the connecting pipe to control the flow of concrete, the operation is convenient, the concrete flow is easy to control, and the pouring speed is increased.

[0016] Furthermore, the side wall of the connecting pipe has a transparent observation window.

[0017] The beneficial effect of adopting the above further solution is that the flow of materials in the connecting pipe can be checked through the observation window, and the concrete flow can be adjusted in time through the gate valve.

[0018] Furthermore, each of the pouring groups also includes a plurality of pipe fixing devices, and the ash chute is fixed to the well wall through the plurality of pipe fixing devices.

[0019] Furthermore, the deceleration device includes a feed pipe, a discharge pipe and a deceleration pier.

The upper end of the feed pipe has a feed port, and the lower end of the discharge pipe has a discharge port. The deceleration pier is installed at the lower part of the feed pipe, and the upper end of the deceleration pier has a deceleration guide slope inclined toward the discharge pipe. The feed port is connected and connected to the lower end of the ash chute.

[0020] The beneficial effect of adopting the above further scheme is that concrete falls from the upper feed port into the deceleration bin and impacts the deceleration pier, which absorbs part of the concrete's energy. After the concrete collides with the deceleration guide slope, the concrete changes its flow direction and flows out through the lower discharge port, and the concrete outlet speed is reduced to a controllable range. During the construction of a kilometer-deep shaft, a deceleration device is connected to the bottom of the ash chute to meet the deceleration buffer requirements of the kilometer-deep shaft, effectively reducing the concrete outlet speed while simplifying the structure of the casting system containing the ash chute, and eliminating pipe blockage accidents.

[0021] Furthermore, each of the pouring groups also includes a hanging plate, which is fixedly connected to the well wall and connected to the secondary mixing funnel.

[0022] Furthermore, it also includes a hydraulic integral template, which is arranged in the well and located below the ash separator.

[0023] The beneficial effect of adopting the above further solution is that the hydraulic integral template is used as a mold to facilitate the casting and molding of the well wall.

[0024] Furthermore, the lower portion of the ash separator has a plurality of ash separator outlets, each of which is connected to the upper end of an ash flowing hose, and the lower end of the ash flowing hose is located outside the hydraulic integral template.

[0042] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0044] The ash storage barrel 200 is used to store concrete and release concrete continuously, so that the pouring process is continuous, the construction quality is guaranteed, and the untimely supply of concrete due to equipment failure is reduced, which forms construction joints and affects the appearance. Self-mixed concrete can be replaced with commercial concrete. The use of commercial concrete makes on-site civilized production more standardized and the concrete mix ratio more accurate.

[0045] A flow control device 100 is provided at the upper end of the ash chute 600 to control the concrete flow, reduce the concrete flow rate, guide the flowing concrete, and reduce the friction of aggregate on the pipeline. The flow controller is fully applied to control the concrete flow rate and flow rate, which not only ensures the continuity of concrete lowering, but also reduces the probability of pipe blockage, and to a certain extent reduces the risk of pipe blockage of the ash chute connected below the ash hopper, ensuring the safety of the pipeline in the wellbore.

[0046] A deceleration device 500 is added to the lower end of the ash chute 600 to reduce the direct impact of concrete on the pipe wall and further reduce the concrete speed.

[0047] The secondary mixing funnel 900 mixes the concrete in the pipeline again to ensure the workability of the concrete. The ash distributor 1000 disperses and pours the concrete to ensure the uniformity of pouring.

[0048] This solution uses pipelines to transport concrete, and the main and auxiliary winches can discharge slag and remove the slag in the well, which optimizes the construction process, reduces operating costs, improves construction efficiency, and reduces equipment investment and management costs. The flow control device 100 and the speed reduction device 500 control the concrete flow and flow rate to make the construction smoother.

[0049] like Figure 3-Figure 6As shown, on the basis of the above technical solution, the flow control device 100 includes an ash hopper 101 and a flow controller 102, the flow controller 102 is installed in the ash hopper 101, the flow controller 102 includes at least two diverter plates 121, the diverter plates 121 are arranged along the radial direction of the ash hopper 101, at least two of the diverter plates 121 are distributed at intervals along the circumference of the ash hopper 101, and at least two of the diverter plates 121 are fixed to each other at one end facing the center of the ash hopper 101, and the lower end of the ash hopper 101 is fixedly connected and communicated with the upper end of the ash pipe 600.

[0050] The flow controller 102 is placed in the ash funnel 101, and after the position is adjusted, it controls the concrete flow, reduces the concrete flow rate, guides the flowing concrete, and reduces the friction of aggregate on the pipeline. The flow controller 102 is fully used to control the concrete flow rate and flow rate, which not only ensures the continuity of concrete lowering, but also reduces the probability of pipe blockage, and to a certain extent reduces the risk of pipe blockage of the ash pipe connected below the ash funnel 101, ensuring the safety of the pipeline in the wellbore.

[0051] The number of the diverter plates 121 can be set as desired, and the multiple diverter plates 121 are evenly distributed or evenly distributed along the circumference. Figure 3 and Figure 4 As shown, there are four diverter plates 121, and the four diverter plates 121 are fixed in a cross shape.

[0052] On the basis of any of the above solutions, the flow controller 102 further includes a positioning plate 122 , the lower end of the positioning plate 122 is fixedly connected to the diverter plate 121 , and the upper end of the positioning plate 122 abuts against the ash hopper 101 .

[0053] The diverter plate 121 is positioned and installed in the ash hopper 101 through the positioning plate 122 .

[0054] Alternatively, the positioning plate 122 is welded or clamped to the ash hopper 101 .

[0055] On the basis of any of the above solutions, the upper end of the positioning plate 122 has a positioning inclined surface, and the positioning inclined surface abuts against the conical surface in the ash hopper 101 .

[0056] The positioning plate 122 abuts against the conical surface in the ash hopper 101 through the positioning inclined surface. The flow controller 102 can be installed and positioned by simply placing the flow controller 102 in the ash hopper 101 .

[0057] Specifically, Figure 3As shown, the upper end of the positioning plate 122 is a triangle, the lower end is a rectangle, and the hypotenuse of the triangle is a positioning slope.

[0058] On the basis of any of the above solutions, there are at least two positioning plates 122 , and the positioning plates 122 are arranged in one-to-one correspondence with the diverter plates 121 and are fixedly connected.

[0059] At least two positioning plates 122 are provided, so that the flow controller 102 has high stability during installation.

[0060] In one specific example, Figure 3 As shown, there are four positioning plates 122 .

[0061] On the basis of any of the above solutions, the flow control device further comprises a quick-connect short pipe 103 , the upper end of which is detachably connected to the lower end of the ash hopper 101 .

[0062] A 15mm long quick-connect short pipe 103 with a quick connector is reserved above the sealing plate, and the ash funnel 101 is connected and fixed firmly by the quick connector. The ash funnel 101 is easy and quick to assemble and easy to maintain and replace.

[0063] On the basis of any of the above solutions, the upper end of the flow controller 102 is in contact with the ash hopper 101 , and the diverter plate 121 is located in the quick-connect short pipe 103 .

[0064] Specifically, the lower end of the quick-connect short pipe 103 is connected to the ash sluice pipe.

[0065] Specifically, the maximum diameter of the flow controller 102 should be smaller than the inner diameter of the quick-connect short tube 103 to ensure that the flow controller 102 can be moved at any time.

[0066] Specifically, the working principle of the flow controller 102 is: by dividing the space inside the quick-connect short pipe 103 and fixing the ash outlet capacity, it plays a role in controlling the concrete flow and maintaining the stability of the flow rate and flow velocity; and in the process of concrete lowering, it also plays a guiding role, reducing the scouring of the concrete on the ash chute pipe orifice, reducing the rebound of aggregates in the pipe, and reducing the wear of the pipeline.

[0067] Based on the above technical solution, Figure 5 and Figure 6 As shown, each pouring group further includes a connecting pipe 300 and a gate valve 400, one end of the connecting pipe 300 is connected and communicated with the ash storage bucket outlet of the ash storage bucket 200, the other end of the connecting pipe 300 is located above the ash hopper 101, and the gate valve 400 is arranged at one end of the connecting pipe 300.

[0068] Ash storage barrels are used to store ash, and the plug valve on the connecting pipe is used to control the flow of concrete. It is easy to operate, easy to control the concrete flow, and increase the pouring speed.

[0069] On the basis of the above technical solution, the side wall of the connecting pipe 300 has a transparent observation window.

[0070] The flow of materials in the connecting pipe can be checked through the observation window, and the concrete flow can be adjusted in time through the gate valve.

[0071] On the basis of the above technical solution, each of the pouring groups further includes a plurality of pipe fixing devices 700 , and the ash chute 600 is fixed to the well wall 1200 through the plurality of pipe fixing devices 700 .

[0072] like Figure 7-Figure 9 As shown, on the basis of the above technical solution, the deceleration device 500 includes a feed pipe, a discharge pipe and a deceleration pier 504, the upper part of one side of the discharge pipe is fixedly connected to the lower part of one side of the feed pipe and are internally connected to form a deceleration bin 503, the upper end of the feed pipe has a feed port 501, the lower end of the discharge pipe has a discharge port 502, the deceleration pier 504 is installed in the lower part of the feed pipe, and the upper end of the deceleration pier 504 has a deceleration guide slope inclined toward the discharge pipe, and the feed port 501 is connected and communicated with the lower end of the ash chute 600.

[0073] Concrete falls from the upper feed port 501 into the deceleration bin 503 and impacts the deceleration pier 504. The deceleration pier 504 absorbs part of the concrete's energy. After the concrete collides with the deceleration guide slope, the concrete changes its flow direction and flows out through the lower discharge port 502. The concrete outlet speed is reduced to a controllable range. During the construction of a kilometer-deep shaft, a deceleration device is connected to the bottom of the ash chute to meet the deceleration buffer requirements of the kilometer-deep shaft. While effectively reducing the concrete outlet speed, it simplifies the structure of the casting system containing the ash chute and eliminates pipe blockage accidents.

[0074] Optionally, the speed reducer 504 is fixed in the feed pipe, or placed in the feed pipe but not connected to the feed pipe.

[0075] Specifically, Figure 7 As shown, the height of the deceleration guide slope gradually decreases from the side away from the discharge pipe to the side close to the discharge pipe.

[0076] On the basis of any of the above solutions, the deceleration device 500 further includes a buffer spring 505 , and the buffer spring 505 is fixedly connected to the bottom surface of the deceleration pier 504 .

[0077] When the concrete flows downward and collides with the deceleration guide slope, the buffer spring 505 is compressed, and the energy is absorbed by the buffer spring 505 below the deceleration pier 504, thereby reducing the vibration of the pipeline.

[0078] Based on any of the above solutions, the buffer spring 505 is a butterfly spring.

[0079] Based on any of the above solutions, the angle a between the deceleration guide slope and the vertical direction is 35°-45°.

[0080] The angle a can ensure that the concrete flows smoothly along the deceleration guide slope to the discharge pipe.

[0081] Based on any of the above solutions, an inspection window 509 is provided on the top of the discharge pipe.

[0082] An inspection window 509 is provided on the upper part of the deceleration bin 503 for confirming that the interior of the deceleration bin 503 is unobstructed and free of attached concrete before each unloading.

[0083] Optionally, the inspection window 509 is made of a transparent material, or the inspection window 509 is movable or rotatable, and opens or closes the top surface of the discharge pipe.

[0084] Based on any of the above solutions, one end of the inspection window 509 is hinged to the discharge pipe, and the other end thereof is detachably connected to the discharge pipe.

[0085] The inspection window 509 can be rotated and opened to facilitate observation of the situation in the deceleration chamber 503 or cleaning of blockages in the deceleration chamber 503 .

[0086] Specifically, Figure 7 As shown, a vertically arranged inspection window pin 508 is fixed on the inspection window 509, and the inspection window pin 508 is hinged to the discharge pipe. The inspection window fixing bolt 510 passes through the other end of the inspection window 509 and the flange on the upper end of the discharge pipe, and is threadedly connected to the fixing nut, thereby realizing a detachable connection between the inspection window 509 and the discharge pipe.

[0087] On the basis of any of the above solutions, the deceleration device 500 further includes a reinforcing steel plate 512, and the reinforcing steel plate 512 is fixedly connected to the outer walls of the feed pipe and the discharge pipe.

[0088] The outer walls of the feed pipe and the discharge pipe are fixed by the reinforcing steel plate 512 , thereby increasing the structural strength of the reduction device 500 and increasing the service life of the reduction device 500 .

[0089] Specifically, there are two reinforcing steel plates 512, which are respectively arranged on both sides of the feed pipe, or the reinforcing steel plates 512 are made into an annular structure and are sleeved on the outer sides of the feed pipe and the discharge pipe.

[0090] Specifically, the thickness of the reinforcing steel plate 512 is 10 mm, which prolongs the service life of the reduction gear.

[0091] On the basis of any of the above solutions, the deceleration device 500 further includes a lifting lug 511 , and the lifting lug 511 is fixedly connected to the reinforcing steel plate 512 .

[0092] A lifting lug 511 is welded on the outer side of the deceleration chamber, which is convenient for fixing the deceleration device 500 on the anchor rod of the well wall using a steel wire rope to ensure construction safety.

[0093] There are one or more lifting ears 511. In one specific example, there are two lifting ears 511, and the two lifting ears 511 are respectively arranged on both sides between the feed pipe and the discharge pipe.

[0094] Based on any of the above solutions, the height difference between the top surface of the discharge pipe and the deceleration guide inclined surface is L, the inner diameter of the feed pipe is D, and L≥2D.

[0095] The height difference L is the net height of the deceleration area of ​​the feed pipe. The value of the height difference L can ensure that the deceleration pier 504 effectively decelerates the concrete, and with the structure of the deceleration guide slope, the concrete can flow smoothly along the deceleration guide slope, reducing the amount of rebound after the concrete collides with the deceleration guide slope.

[0096] Specifically, the height difference between the top surface of the discharge pipe and the deceleration guide inclined surface is L, which refers to: the difference between the height of the top surface of the discharge pipe and the height at which the deceleration guide inclined surface coincides with the axis of the feed pipe.

[0097] On the basis of any of the above solutions, the upper end of the feed pipe is welded with a quick connector 507 to be connected to the upper ash sluice pipe, and the lower end of the discharge pipe is welded with a discharge pipe flange 506 to be connected to the lower rubber hose.

[0098] In one specific example, both the feed pipe and the discharge pipe are made of wear-resistant steel pipes with an outer diameter of 180 mm and a thickness of 10 mm. The quick connector 507 welded on the upper end of the feed pipe is connected to the upper ash pipe with an outer diameter of 159 mm and a thickness of 10 mm. The outer diameter of the feed pipe is slightly larger than the upper ash pipe. The deceleration pier 504 is made of a solid steel column with a diameter of 150 mm, and the upper end of the steel column is cut into a 40° bevel. The lifting lugs 511 are made of 10 mm thick steel plates and welded on both sides of the deceleration chamber 503, which is convenient for fixing the device to the anchor rod of the well wall using wire ropes to ensure construction safety.

[0099] On the basis of the above technical solution, each of the pouring groups further includes a hanging tray 800 , and the hanging tray 800 is fixedly connected to the well wall 1200 and connected to the secondary stirring funnel 900 .

[0100] The secondary mixing funnel 900 is suspended in the middle of the wellbore by a hanging plate 800.

[0101] On the basis of the above technical solution, it also includes a hydraulic integral template 1100, which is arranged in the well and located below the ash separator 1000.

[0102] The hydraulic integral formwork 1100 is used as a mold to facilitate casting and molding of the well wall.

[0103] Specifically, the upper end of the hydraulic integral template 1100 is made with an inclined opening inclined toward the shaft axis direction (inside the shaft) to facilitate pouring of concrete between the outer side of the hydraulic integral template 1100 and the inner side of the shaft, thereby forming a concrete shaft wall 1200.

[0104] On the basis of the above technical solution, the lower part of the ash separator 1000 has a plurality of ash separator outlets, each of which is connected to the upper end of an ash hose, and the lower end of the ash hose is located outside the hydraulic integral template 1100.

[0105] The concrete is poured to various locations through the ash distributor 1000 and multiple ash hoses, and the well wall 1200 is poured evenly.

[0106] Specifically, the lower end of the ash hose is located in the oblique opening at the upper end of the hydraulic integral template 1100.

[0107] On the basis of the above technical solution, the casting groups are provided with two groups, and the two groups of casting groups are symmetrically arranged on both sides of the kilometer-deep well.

[0108] Two pouring groups are used to pour concrete simultaneously, which increases the pouring efficiency.

[0109] Specifically, the multiple ash hoses of the two pouring groups are evenly distributed along the circumference of the well wall 1200. Thus, the poured well wall 1200 is more uniform.
