[0001] The invention relates to the technical field of water conservancy engineering, in particular to a dam curtain grouting hole device and a construction process thereof. Background Art

[0002] Dam anti-seepage curtain grouting is an important anti-seepage treatment technology in water conservancy projects.

The upper end of the traction plate 8 is rotatably connected with a traction rod 9. One end of the preparation and processing box 1 is provided with a through opening 10 corresponding to the traction rod 9. One end of the traction rod 9 is rotatably connected with a linkage kit 37, which is rotatably connected to one end of the screening groove 18. The crushed stone mixture is put into the feed hopper 3, and the put-in material enters the screening groove 18 in the preparation and processing box 1. The personnel turn on the switch of the drive motor 5 from the external controller. After the drive motor 5 is running, the output shaft drives the second bevel gear 19 rotates, and the first bevel gear 7 is driven to rotate with the rotation of the second bevel gear 19. When the first bevel gear 7 rotates, it drives the rotating shaft 6 to rotate, so that the traction plate 8 is driven to rotate and the traction rod 9 is driven to move continuously in the through port 10.

[0021] Embodiment 2: Based on Embodiment 1, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, a material distribution component 552 is movably installed inside the screening groove 18, and the material distribution component 552 includes a material distribution mesh plate 21 movably arranged inside the screening groove 18, and a clamping groove 29 opened on the two side walls of the screening groove 18, and a limiting block 30 is slidably arranged inside the clamping groove 29.

The adjustment component 555 includes a sleeve 31 arranged at the bottom end of the screening groove 18. , and a limit block 32 slidably arranged on the inner side of the sleeve 31, the upper end of the limit block 32 is fixedly connected with the sleeve 31, the limit block 32 is rotatably connected with the top rod 20, the bottom end of the sleeve 31 is provided with a bottom opening 33, the bottom end of the limit block 32 is fixedly connected with an L-shaped rod 23 interlaced with the bottom opening 33, a hydraulic push rod 11 is fixedly installed at one end of the preparation processing box 1, the extended end of the hydraulic push rod 11 is fixedly connected with the L-shaped rod 23, and a discharge port 3 is provided at the bottom end of the screening groove 18 5. A transfer hopper 34 corresponding to the discharge port 35 is interspersed inside the preparation and processing box 1. A discharge pipe 4 used in conjunction with the transfer hopper 34 is fixedly connected to one end of the preparation and processing box 1. After a predetermined working time, a person turns on the switch of the hydraulic push rod 11 from an external controller. After the hydraulic push rod 11 operates, it contracts and drives the L-shaped rod 23 to move. After the L-shaped rod 23 moves, it drives the limit block 32 to slide smoothly in the bottom port 33. When the limit block 32 slides, it pushes the top rod 20 to move. The push of the push rod 20 drives the dividing mesh plate 21 to move, and after the movement of the dividing mesh plate 21, the limiting block 30 is driven to slide on the inner side of the slot 29. As the push of the push rod 20 is applied, the dividing mesh plate 21 begins to rotate around the limiting block 30.

[0022] Embodiment 3: Based on Embodiment 1, Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, a temperature control box 12 is arranged inside the preparation and processing box 1, and a mixing assembly 554 is fixedly installed on the inner side of the temperature control box 12. The mixing assembly 554 includes a mixing drum 13 fixedly installed obliquely inside the temperature control box 12, and a mixing plate 22 rotatably installed inside the mixing drum 13.

A feeding port 16 corresponding to the distribution hopper 17 is provided at the upper end of the temperature control box 12. The L-shaped rod 23 is movably arranged to be interlaced with the distribution hopper 17. Under the continuous screening operation of the groove 18, qualified stone mortar materials are screened and fall from the dividing mesh plate 21 into the dividing hopper 17 below the screening groove 18. The materials falling into the dividing hopper 17 enter the temperature control box 12 from the inlet 16 for temperature control to prevent the entering materials from agglomerating due to too low temperature, and then enter the mixing barrel 13 for mixing. Then, under the operation of the driving motor 5, the output shaft drives the central axis of the mixing plate 22 to rotate, so that the mixing plate 22 continuously mixes the material powder and the forming agent, speeds up the preparation efficiency, and ensures the fluidity of the mixed mortar. After mixing, the personnel open the sealing door 14 to allow the mixed fluid mortar to be discharged through the discharge bridge 15 for use, which is beneficial to ensure the mixing quality.

[0023] like Fig. 9 As shown, the present invention also provides a construction process of a dam curtain grouting hole device, which is used for construction of a dam curtain grouting hole device, and the construction steps of the process are as follows: S1. The lifting monitoring hole is installed before grouting construction; S2. The lifting hole is drilled using XY-2B geological drilling rig with diamond rotary drilling, the drilling diameter is 76mm, and the hole is drilled all the way to the bottom. After drilling, the lifting observation device is installed; S3. During the flushing of borehole cracks, water pressure test and grouting using grouting hole equipment, the lifting deformation observation should be carried out and detailed records should be made; S4. After the grouting work of the unit project is completed, the deformation observation hole is lifted and sealed.

[0024] The above detailed process is as follows Fig. 9 As shown, the hole position is measured first, and the slurry water-cement ratio table is according to Table 1 below. The arrangement of all drill holes is strictly in accordance with the design requirements. Steel pipes are embedded during the construction of the anti-seepage wall. The position of the embedded pipe is measured and verified before construction. The hole position meets the design regulations and requirements. The deviation between the opening hole position of this curtain grouting and the design position is no more than 10cm.

[0025] The drilling is done using an XY-2 geological drilling rig in combination with a diamond drill bit and clean water drilling.

[0026] The drilling is done using a geological rotary drill rig combined with a diamond drill bit, and the curtain grouting hole diameter is φ76mm.

[0027] The deviation between the drilling hole position and the design position shall not exceed 10cm. The drilling depth shall be based on the design depth, and the final hole depth shall be 5m below the relatively impermeable layer (q≤5Lu). If the requirement of q≤5Lu cannot be met, the grouting depth shall be deepened to 5m below q≤5Lu on the basis of the design hole depth. The actual depth, hole position and hole inclination of each drilling hole shall be recorded.

[0028] During the drilling process, keep detailed records of the drilling operations (including the color of the drilling flushing water, water pressure, drilling pressure, core sample length and other factors that can fully reflect the characteristics of the rock or concrete).

[0029] (1) To ensure that the hole inclination requirements are met during construction, the following measures are taken: ① After the drill rod of the drilling rig is aligned with the center of the hole, use a level ruler with an accuracy of 2‰ to adjust the vertical axis in two directions (front, back, left, and right) to be vertical. The deviation rate of the vertical axis of the drilling rig shall not exceed 2‰.

[0030] ② Use ground anchor bolts to connect to the construction platform to fix the drilling rig to prevent displacement during construction.

[0031] ③ During construction, the stability of the drilling rig and the plumbness of the drilling rig's vertical axis should be checked frequently, and combined with the inclination measurement results, measures such as lengthening the thicker-diameter drill tools and appropriately controlling the drilling pressure should be taken to prevent the borehole from deviating beyond the standard.

[0032] ④ During the drilling process, check the angle of the vertical axis at any time and adjust it at any time.

[0033] ⑤ During drilling, strictly control the deviation of hole depth within 20m.

[0034] (2) During the construction, hole inclination measurements were carried out at each grouting section using a KXP-1 inclinometer.

[0035] When flushing the borehole, the grouting hole section uses pressurized water to flush the hole wall and cracks before grouting until the return water is clean, which lasts for 10 minutes. The thickness of the residual deposit in the hole after flushing is no more than 20cm. The flushing pressure is 80% of the grouting pressure of this section and is not more than 1.0MPa.

[0036] During the water pressure test, the curtain grouting holes are tested in sections from top to bottom. The pilot hole and the inspection hole are tested by single-point water pressure, and the other curtain grouting hole sections are tested by simple water pressure before grouting. The water pressure test pressure is 80% of the grouting pressure of the section and is not greater than 1.0Mpa. The water pressure is 20 minutes, and the pressure flow is measured every 5 minutes. The final flow value is taken as the calculated flow.

[0037] During the construction of pilot holes and inspection holes, cores are drilled and taken from the grouting pilot holes and inspection holes, and they are uniformly numbered, packed with labels, and a borehole column chart is drawn and a core description is performed according to the coring order. The water pressure test of each section of the pilot hole and inspection hole is carried out at 80% of the grouting pressure, and the necessary data must be recorded, including hole number, section length, pressure gauge elevation, groundwater level elevation, water pressure pressure, flow rate, water pressure time and permeability.

[0038] The grouting construction steps are as follows: (1) The curtain grouting under the longitudinal reinforcement body adopts the "curtain grouting first section top hole closing, top-down, segmented circulation method" grouting, and the distance between the grouting pipe and the bottom of the hole is no more than 0.5m during grouting.

[0039] (2) The grouting of the first section (orifice pipe section) is carried out by the plug method. During grouting, the grouting plug is set in the concrete at a distance of 0.3 m from the concrete bottom plate.

[0040] (3) After the first section is grouted, it should be left to set for 24 hours. If there is no water gushing out of the hole mouth of the remaining sections, it is generally not necessary to wait for setting after the grouting is completed, and the next section of drilling and grouting can be carried out directly.

[0041] Pre-buried orifice pipe Curtain grouting is carried out through pre-buried steel pipes in the anti-seepage wall, with a pipe spacing of 2.0m and an orifice pipe diameter of 110mm.

[0042] Table 1 is the water-cement ratio of the slurry

[0043] When the present invention is used, the user first operates to put the crushed stone mixture from the feed hopper 3, and the put-in material enters the screening groove 18 in the preparation and processing box 1. The personnel turn on the switch of the drive motor 5 from the external controller. After the drive motor 5 is running, the output shaft drives the second bevel gear 19 to rotate, and the first bevel gear 7 is driven to follow the rotation under the rotation of the second bevel gear 19. When the first bevel gear 7 rotates, it drives the rotating shaft 6 to rotate, so that the traction plate 8 is driven to rotate and the traction rod 9 is driven to continuously move in the through port 10. Under the movement of the traction rod 9, the linkage kit 37 is driven to continuously move. After the linkage kit 37 moves, the screening groove 1 is pulled. 8 is movable, and when the screening groove 18 moves, it drives the shaking slider 28 to move continuously in the limit groove 26. Under the action of the protrusion 27, the shaking slider 28 shakes up and down continuously when it moves, so that the incoming stone materials are constantly swung and shaken. At the same time, when the screening groove 18 moves, it drives the sleeve block 24 to slide back and forth in the fixed rod 36, which has better stability. Under the continuous screening operation of the screening groove 18, qualified stone mortar materials are screened and fall from the material distribution mesh plate 21 to the material distribution hopper 17 below the screening groove 18. The materials falling into the material distribution hopper 17 enter the temperature control box 12 from the feed inlet 16 for temperature control to prevent the temperature from being too high. If the material is too low, it will cause the material to agglomerate, and then enter the mixing barrel 13 for mixing. Then, under the operation of the driving motor 5, the output shaft drives the central axis of the mixing plate 22 to rotate, so that the mixing plate 22 continuously mixes the material powder and the molding agent, speeds up the preparation efficiency, and ensures the fluidity of the mixed mortar. After mixing, the personnel open the sealing door 14, so that the mixed fluid mortar material is discharged through the discharge bridge 15 for use, and the stone powder is continuously screened through the separation component 551. After working for a predetermined time, the personnel turn on the switch of the hydraulic push rod 11 from the external controller. After the hydraulic push rod 11 is operated and retracted, it drives the L-shaped rod 23 to move. After the profile rod 23 moves, it drives the limit block 32 to slide smoothly in the bottom opening 33, and when the limit block 32 slides, it pushes the top rod 20 to move, and the material dividing mesh plate 21 is driven to move under the push of the top rod 20. After the movement of the material dividing mesh plate 21, it drives the limit block 30 to slide on the inner side of the slot 29. With the push of the top rod 20, the material dividing mesh plate 21 begins to rotate around the limit block 30. After the limit block 30 rotates to a certain angle, the screened stone impurity particles are discharged, so that they fall from the discharge port 35 to the transfer hopper 34, and then are discharged from the discharge pipe 4 to the outside of the device for processing, and then the direction of the hydraulic push rod 11 is operated to reset the material dividing mesh plate 21.
