Description

Technical Field

[0001] The invention belongs to the technical field of grouting, and in particular relates to a concrete dam curtain grouting construction system and a construction method thereof. Background Art

[0002] Curtain grouting is a common waterproofing and reinforcement measure in underground projects. It is widely used in projects such as dams, tunnels, and subways. In the process of curtain grouting, the slurry usually includes conventional slurry composed of cement, chemical additives and water, as well as some special slurries, which are poured into the underground rock formation to form a watertight layer. The curtain grouting system usually consists of a drilling rig, a drill rod, a slurry inlet pipe, a grouting pump, and a slurry storage mixer. The slurry storage mixer is used to store the slurry to be injected, and usually includes a storage barrel with a heating unit and a stirring structure installed on the storage barrel to ensure that the slurry remains uniform during the grouting process to avoid sedimentation or stratification. The grouting pump is responsible for pumping the slurry from the slurry storage mixer to the slurry inlet pipe, and the slurry inlet pipe is responsible for transporting the slurry from the grouting pump to the underground grouting hole or working surface. During the use of this existing curtain grouting construction system, the slurry inlet pipe is usually connected to the drill rod, and the slurry is transported downward through the drill rod. However, there is a lack of necessary protection between the drill rod and the power head of the drilling rig. The drill rod is prone to damage itself and the power head during the process of compression, displacement and vibration, which reduces the working stability and service life of the curtain grouting construction system. At the same time, when used in cold outdoor environments, the slurry storage mixer has an unsatisfactory insulation effect on the slurry, and lumps are easily generated in the slurry, thereby clogging the slurry inlet pipe, further reducing the working stability of the curtain grouting construction system. Therefore, it is necessary to make improvements. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] The embodiment of the present application provides a concrete dam curtain grouting construction system, including: a base 1, a drilling rig 2 is arranged on the base 1, and a power head 200 is arranged on the drilling rig 2; a hanger 3, the hanger 3 is arranged on the ground, and a hanging wheel 300 is arranged on the top of the hanger 3; a hoisting device 4, the hoisting device 4 is arranged on the drilling rig 2; a drill rod 5, the drill rod 5 is passed through the power head 200, and a slurry inlet part 500 is arranged on the top of the drill rod 5; a slurry inlet pipe 6, the slurry inlet pipe 6 is connected to the slurry inlet part 500; a control part 7, the control part 7 is arranged on the drilling rig 2, and the control part 7 includes a plurality of operating rods and a distribution box equipped with control elements; a protective sleeve rod 8, the protective sleeve rod 8 is arranged at the bottom of the power head 200; The protective sleeve rod 8 is sleeved on the outer side of the drill rod 5 .

[0031] Moreover, the protective sleeve rod is in the shape of a hollow rod, and the protective sleeve rod vertically extends downward from the bottom of the power head, and the inner diameter of the protective sleeve rod is less than or equal to the diameter of the drill pipe.

[0032] In this embodiment, the drill rod 5 can be effectively protected by the provision of the protective sleeve rod 8. When the drill rod is compressed, displaced and vibrated during operation, the drill rod swings in the radial direction. At this time, the protective sleeve rod can effectively limit the displacement of the drill rod and reduce the force arm of the drill rod when the displacement and vibration of the drill rod produce a bending tendency, thereby preventing the drill rod 5 from being damaged during the process of compression, displacement and vibration and causing damage to the power head 200, thereby improving the working stability and service life of the curtain grouting construction system.

[0033] This embodiment provides a concrete dam curtain grouting construction system, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes: a slurry storage mixer, the slurry storage mixer includes a storage bucket 9 with a heating unit and a stirring mechanism 10 arranged on the storage bucket 9; a control unit 11, the control unit 11 is arranged on the side wall of the storage bucket 9; The grout inlet pipe 6 is connected to the storage barrel 9 through a grouting pump, and the heating unit is an electric heating wire arranged in the barrel wall of the storage barrel 9.

[0034] It also includes: a plurality of material blocking plates 12, which are arranged on the inner wall of the storage barrel 9, and the plurality of material blocking plates 12 are evenly spaced and distributed along the circumference of the storage barrel 9; The material blocking plate 12 is bent and extends from the top of the storage barrel 9 to the bottom.

[0035] The material blocking plate is in the shape of a mesh plate.

[0036] Moreover, the heating unit is a conventional electric heating wire structure, which is controlled by the control unit 11.

[0037] In the present embodiment, the slurry in the storage barrel 9 is stirred by the stirring mechanism 10 to maintain the uniformity of the slurry. When it is in a cold outdoor environment, the heating unit is started to heat the slurry in the storage barrel 9 to prevent the slurry from agglomerating. At the same time, while the slurry is being stirred by the stirring mechanism 10, the agglomerated slurry will move toward the barrel wall of the storage barrel 9 under the action of centrifugal force. When the agglomerated slurry moves to the barrel wall, the blocking plate 12 can intercept the agglomerated slurry. After being intercepted, the agglomerated slurry stays on the blocking plate 12, thereby contacting the barrel wall for a long time and finally being fully heated and dissolved. After the agglomerated slurry is dissolved, it is fully integrated into the liquid slurry. Compared with the prior art, the present invention can effectively improve the heating effect of the agglomerated slurry, thereby further improving the uniformity of the slurry, preventing the agglomerated slurry from clogging the slurry inlet pipe 6, and improving the working stability of the curtain grouting construction system.

[0038] The present embodiment provides a concrete dam curtain grouting construction system, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the stirring mechanism 10 also includes: a stirring motor 100, which is arranged at the top of the storage bucket 9 through a motor bracket; a stirring shaft 101, which is rotatably arranged in the storage bucket 9; a stirring part 102, which is arranged at the bottom of the stirring shaft 101, and the stirring part 102 includes a plurality of stirring blades 1020 with variable angles; a stirring blade control member 13, which is arranged at the top of the storage bucket 9; The stirring portion 102 and the stirring blade control component 13 are both electrically connected to the control unit 11 , and the stirring blade control component 13 can control the angle of the stirring blade 1020 to change according to the increase in the rotation speed of the stirring shaft 101 .

[0039] The stirring part 102 also includes: a central shaft 1021, which is arranged at the bottom end of the stirring shaft 101, and a rotating cavity 1022 is arranged in the central shaft 1021; an arc-shaped slide groove 1023, which is arranged on the side wall of the central shaft 1021 and penetrates into the rotating cavity 1022, and there are a plurality of arc-shaped slide grooves 1023, and the plurality of arc-shaped slide grooves 1023 are evenly spaced along the circumference of the central shaft 1021; a slider 1024, and the slider 1024 is slidably arranged on the arc-shaped slide groove 1023; a rotating disk 1025, which is rotatably arranged in the rotating cavity 1022, and a plurality of limiting clamps 1026 are arranged on the surface of the rotating disk 1025, and the plurality of limiting clamps 1026 are evenly spaced along the circumference of the rotating disk 1025; a mounting shell 1027, which is arranged at the bottom of the central shaft 1021, and a rotating motor 1028 is arranged in the mounting shell 1027; Among them, the root of the stirring blade 1020 is connected to the outer end of the slider 1024, the inner end of the slider 1024 cooperates with the limiting clamp 1026 and moves along the arc-shaped slide groove 1023 driven by the rotating disk 1025, and the driving end of the rotating motor 1028 is connected to the rotating disk 1025.

[0040] Moreover, the bottom of the mounting shell 1027 also has a conventional motion power supply structure, such as a brush and a conductive ring, and the power supply structure is electrically connected to the control unit 11.

[0041] In this embodiment, when the stirring mechanism 10 stirs the slurry, the stirring motor 100 starts to drive the stirring shaft 101 to rotate. At this time, the angle between the stirring blade 1020 and the horizontal plane is small, and the resistance encountered by the stirring blade 1020 when driving the slurry to rotate is also small. Therefore, the resistance encountered by the stirring motor 100 when driving the stirring shaft 101 to rotate is small, which effectively reduces the load of the stirring motor 100 during the starting process. As the stirring motor 100 increases the speed, the slurry is stirred and rotates in the storage bucket 9. At this time, the stirring blade control component 13 controls the rotating motor 1028 to rotate, and the rotating disk 1025 drives the limiting clamp 1026 to rotate with the rotation of the rotating motor 1028. During the rotation of the limiting clamp 1026, the slider 1024 is driven to move along the arc-shaped slide groove 1023. Due to the curvature of the arc-shaped slide groove 1023, the slider 1024 will drive the connected The stirring blade 1020 moves, thereby changing the angle between the stirring blade 1020 and the horizontal plane. The increased angle of the stirring blade 1020 improves the stirring effect on the slurry, thereby further increasing the rotation speed of the slurry. Since the slurry is already in a rotating state, the state change of the stirring blade 1020 at this time will not further increase the load of the stirring motor 100. As the stirring motor 100 continuously increases the rotation speed of the stirring shaft 101, the stirring blade 1020 continuously adjusts its state under the control of the stirring control component, and after adjusting to the final state, it stably stirs the slurry to maintain the uniformity of the slurry. Compared with the prior art, the present invention can effectively reduce the load of the stirring motor 100 while ensuring the slurry stirring effect, reduce energy consumption, prevent the stirring motor 100 from overheating and damage, and further improve the working stability of the curtain grouting construction system.

[0042] The present embodiment provides a concrete dam curtain grouting construction system, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the stirring blade control member 13 also includes: a first shell 130, the first shell 130 is arranged on the top of the storage bucket 9, and a rotating shaft 131 is rotatably arranged in the first shell 130; a plurality of rod groups 132, the rod group 132 is composed of two rod groups 132, the plurality of rod groups 132 are radially symmetrically distributed along the rotating shaft 131 and are evenly spaced along the axial direction of the rotating shaft 131, an adsorption magnet 133 is arranged at the bottom of the rod group 132, and a limit cover 134 is arranged at the top of the rod group 132; a control button 135, a control There are a plurality of buttons 135, and the control buttons 135 are arranged on the surface of the rotating shaft 131 and at the bottom of the rod group 132; there are a plurality of button pressing blocks 136, and the button pressing blocks 136 are movably arranged on the rod group 132; a second shell 137, and the second shell 137 is arranged on the top of the storage bucket 9, and a conductive rod 138 is rotatably arranged in the second shell 137, and the conductive rod 138 is coaxially connected with the rotating rod, and a conductive plate 139 is arranged at one end of the conductive rod 138 away from the rotating rod; a conductive clip 1310, and the conductive clip 1310 is arranged in the second shell 137, and a conductive brush head 14 is arranged at the end of the conductive clip 1310; Among them, the rotating shaft 131 is connected to the stirring shaft 101 through a bevel gear group 1311, the suction force of the adsorption magnet 133 at the bottom of the plurality of rod groups 132 increases successively, the button pressing block 136 can be adsorbed by the adsorption magnet 133, the edge of the conductive disk 139 is located in the conductive clip 1310, the end of the conductive brush head 14 is electrically contacted with the conductive disk 139, and the conductive clip 1310 is electrically connected to the control unit 11.

[0043] Moreover, the rotating rod has a cavity inside, in which conventional wires can be distributed, and the wires are respectively connected to the button and the conductive sheet. The bottom of the rod is fixedly connected to the rotating rod, and the length direction of the rod extends radially along the rotating rod.

[0044] In this embodiment, the control unit 11 controls the stirring motor 100 to start. At this time, the stirring blade 1020 is in the initial state. When the stirring motor 100 drives the stirring shaft 101 to rotate, the rotating shaft 131 rotates together under the action of the bevel gear group 1311. As the speed of the stirring shaft 101 increases, the one with the smallest adsorption force in the button pressing block 136 overcomes the suction force of the adsorption magnet 133 under the action of centrifugal force and is thrown to the outer end of the rod group 132. At this time, the corresponding control button 135 is released, and the electrical signal is transmitted to the control unit 11 through the second shell 137, the conductive brush head 14 and the conductive clip 1310. The control unit 11 controls the rotating motor 1028 to rotate, thereby driving the rotating disk 1025 to rotate. When the rotating disk 1025 rotates, the slider 1024 is driven to move along the arc-shaped slide groove 1023 through the limiting clamp 1026, and finally the stirring blade 1020 is adjusted. As the speed of the stirring shaft 101 further increases, one of the button pressing blocks 136 further overcomes the adsorption of the adsorption magnet 133 with larger adsorption force, thereby releasing a corresponding The control button 135 is pressed again, and the stirring blade 1020 is adjusted again. After the speed of the stirring shaft 101 reaches the highest, the last button pressing block 136 overcomes the suction force of the adsorption magnet 133 with the largest adsorption force, thereby releasing the last control button 135, and the stirring blade 1020 is adjusted to the final state. After the stirring stops, as the speed of the stirring shaft 101 decreases, the centrifugal force exerted on each button pressing block 136 gradually decreases, so that it falls back to the bottom of the rod group 132 and is re-adsorbed by the adsorption magnet 133, and each control button 135 is pressed again to make the stirring blade 1020 return to the initial state.

[0047] This embodiment provides a construction method of a concrete dam curtain grouting construction system, which, in addition to the technical solution of the above embodiment, includes the following steps: S1 Arrange the grouting system on the construction hole and prepare the grout; S2 drills and fills in sequence; S3 During the drilling and grouting process, control the operation of the slurry storage mixer to maintain the uniformity of the slurry.

[0048] Step S3 also includes: S30 In the first stirring stage, the control unit 11 controls the stirring motor 100 to start. At this time, the stirring blade 1020 is in an initial state, and the angle between the stirring blade 1020 and the horizontal plane is 10-30 degrees. When the stirring motor 100 drives the stirring shaft 101 to rotate, the rotating shaft 131 rotates together under the action of the bevel gear set 1311, and the slurry is stirred under the action of the stirring blade 1020; S31 In the second stirring stage, as the rotation speed of the stirring shaft 101 increases, the one with the smallest adsorption force in the button pressing block 136 overcomes the suction force of the adsorption magnet 133 under the action of centrifugal force and is thrown to the outer end of the rod group 132. At this time, the corresponding control button 135 is released, and the electrical signal is transmitted to the control unit 11 through the second shell 137, the conductive brush head 14 and the conductive clamp 1310. The control unit 11 controls the rotation motor 1028 to rotate, thereby driving the rotating disk 1025 to rotate. When the rotating disk 1025 rotates, the slider 1024 is driven to move along the arc-shaped slide groove 1023 through the limit clamp 1026, and finally the stirring blade 1020 is adjusted. After the adjustment, the stirring blade 1020 is in the second state, and the angle between the stirring blade 1020 and the horizontal plane is 30-50°; S32: In the third stirring stage, as the rotation speed of the stirring shaft 101 further increases, one of the button pressing blocks 136 further overcomes the adsorption of the adsorption magnet 133 with greater adsorption force, thereby releasing a corresponding control button 135, and the stirring blade 1020 is adjusted again and enters the third state, and the angle between the stirring blade 1020 and the horizontal plane is 50-70°; S33 Final stirring stage: after the stirring shaft 101 reaches the highest speed, the last button pressing block 136 overcomes the suction force of the adsorption magnet 133 with the largest adsorption force, thereby releasing the last control button 135, and the stirring blade 1020 is adjusted to the final state, and the angle between the stirring blade 1020 and the horizontal plane is 70-90°.

At the same time, during the slurry stirring process, by gradually increasing the motor speed and coordinating the angle adjustment of the stirring blades 1020, the load of the stirring motor 100 can be effectively reduced while ensuring the slurry stirring effect, thereby reducing energy consumption and preventing the motor from overheating and damage, thereby further improving the working stability of the curtain grouting construction system.
