Description

Technical Field

[0002] Directional drilling across rivers is a trenchless construction technology widely used in projects where pipelines cross rivers, lakes, roads or other obstacles. Its core is to use a directional drill to drill holes below the surface according to the designed trajectory, and then drag the pipeline into the hole to complete the laying, avoiding damage to the surface environment. It has the advantages of environmental protection, short construction period, low cost, and suitability for complex terrain.

[0003] The patent with application number CN202210162020.3 mentions "a directional drilling crossing construction method for rock formations". The patented construction method is simple, reduces replacement costs, and is convenient and quick to disassemble and install. An anti-blocking structure is provided during the backhaul construction to avoid steel pipe blockage, reduce the steps of cleaning steel pipes, and effectively reduce the cost of pipeline use. It is suitable for promotion and use, and is mainly used in pipeline construction in rock formations.

[0004] However, when the existing technology is used to continuously excavate the soil, the excavation distance is lengthened and the speed and pressure of the injected water flow do not change, resulting in a decrease in water pressure inside the pipeline, which affects the rotation speed of the front end of the directional drill, resulting in a decrease in rotation speed and excavation speed, affecting the processing efficiency. At the same time, when the mud is pressurized and injected, the pressure cannot be controlled and monitored in real time, resulting in pressure changes, affecting the uniformity of the equipment's excavation, and thus greatly affecting the efficiency of excavation and drilling.

[0033] A method for using mud in directional drilling across a river, according to the above technical solution, includes the following steps:

[0034] S1. Excavation Preparation: The load-bearing processing frame is placed at the excavation location by traction equipment. The lifting hydraulic cylinder drives the sliding linkage block, the processing frame, and the operating bottom support frame to rotate and lift. The integrated double supporting frame is rotated and tilted. The positioning hydraulic cylinder drives the integrated double supporting frame to move. The mud raw material is placed in the inner side of the material processing box, and water is injected into the inner side of the operating storage box to complete the excavation preparation.

[0035] S2. Excavation: The internal threaded compression sleeve and the high-pressure cutter are threaded together, and the threaded pipe and the high-pressure cutter are combined through the threaded pair. The internal threaded compression sleeve is driven to rotate by the motor and the belt transmission box. The mud is extracted through the external pipe rack, the injection pipe rack and the booster pump. The water injection buffer box, the water inlet operating pipe, the electric push rod and the conical flow limiter are used to control the mud speed and mud pressure. The rotary cutting process is used to achieve soil excavation.

[0036] S3. Liquid recovery: The mixed liquid discharged from the excavation is sprayed back to the inside of the centralized collection box. The mixed liquid is driven by the reflux pipe rack and the reflux pump to flow back into the diversion treatment box. It is separated by the diversion mesh plate. The hydrocyclone and the horizontal centrifuge are used to centrifuge the mud. The reflux injection pipe, the drainage treatment pipe and the drainage pump are used to drive the mud back to achieve mud reflux recovery:

[0037] S4. Circulation excavation: The slurry is returned through the hydrocyclone and horizontal centrifuge, the slurry and the slurry treatment material are mixed by the multi-chamber mixing box and the material treatment box, the stirring motor and the stirring pusher are used for stirring, and the slurry is utilized and treated in conjunction with the external pipe rack, injection pipe rack and booster pump to achieve continuous circulation excavation.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. A double-mixing assembly is provided. The mud is injected into the hydrocyclone through the injection pump and the injection operation pipe. The mud is injected into the horizontal centrifuge through the external overflow pipe, the relay storage box, the entry operation pipe and the injection pump. The mud is fully separated by two sets of centrifugal treatment. The mud is injected into the inner side of the operation storage box through the reflux injection pipe. The mud is injected into the inner side of the multi-cavity mixing box through the external pipe rack, the injection pipe rack and the booster pump. The mud proportioning material is injected into the multi-cavity mixing box through the feeding operation pipe and the material processing box. The material is mixed by the stirring motor and the stirring pusher to achieve continuous mud mixing processing. The external pipe rack is controlled by the limiting valve to achieve multiple groups of mixed materials in the external pipe. The mud is mixed with the water injection buffer box to facilitate the coordination of different proportions and increase the mixing speed. The viscosity of the mud can be changed according to the soil environment during excavation, which improves the effect of mud use. The water inlet speed of the water inlet operation pipe is changed by inserting the electric push rod to drive the tapered cable block. The spring telescopic rod is used to drive the multi-hole external spray frame to separate from the fixed combination frame, and the pressure sensor is used to detect the mud pressure. The mud mixing speed and mud feeding speed are adjusted according to the length of the pipeline. At the same time, the mud injection position and injection amount are adjusted to achieve the uniformity of mud feeding and the stability of pressure during continuous excavation. The processing speed and rotation speed of the high-pressure cutter are guaranteed, and the stability and efficiency of excavation are improved.

[0040] The lifting hydraulic cylinder drives the sliding linkage block, cooperates with the processing frame and the operating bottom support frame to rotate and rise, cooperates with the positioning hydraulic cylinder to drive the integrated double matching frame to move, adjusts the excavation angle and excavation position, and the hydraulic motor and mobile screw drive the pressing operation frame and the load-bearing limit sleeve to move. The spacing of the equipment is adjusted according to the length of the pipeline and equipment to achieve steady processing operation. The internal thread pressing sleeve is used to drive the entry threaded pipe and high-pressure cutter to rotate. The rotary feeding and rotary reversing are used in conjunction with stable water pressure impact cutting to increase the excavation speed. The mobile pressing processing, rotary reversing and rotary feeding processing can increase the entry speed, thereby coping with different excavation environments and improving the scope of application of the equipment.

[0041] Through two groups of centrifugal separation, the speed and effect of mud separation are improved, and multiple groups of mud proportioning mixing and mud injection mixing are coordinated, as well as flow mixing and mud mixing. Double pump feeding and mobile adjustment of the liquid inlet speed of the water inlet operating pipe are used, and continuous rotation combination and push-in excavation are coordinated with each other. This effectively solves the problem in the existing technology that when long-distance soil excavation is carried out, the mud pressure decreases due to the lengthening of the pipeline, affecting the speed of directional drilling and the impact cutting speed of the soil. By changing the mud inlet speed and increasing the mud inlet pressure, the excavation efficiency is effectively improved. Multi-stage monitoring and adjustment are used to control the pressure to avoid excessive high pressure affecting the stability of the equipment connection, improve the speed and stability of excavation and drilling, achieve steady excavation processing, and improve the excavation efficiency and the stability of mud use.

[0042] 2. Equipped with multiple external discharge components, the external discharge mud mixture is centrally processed through the centralized collection box. The external discharge hydraulic cylinder drives the external discharge slag plate to discharge the sedimentation debris. The reflux pump and the reflux pipe rack are used to spray the mixed liquid into the inner side of the diversion treatment box to achieve continuous reflux and slag removal, thereby increasing the speed of the mud mixture reflux. The mixed liquid is separated and processed by the diversion mesh plate. The external push-out electric slide drives the external push-out slag plate to push the crushed stone to move, thereby achieving preliminary separation of the mixed liquid. The elastic separation mesh plate is used to carry the filtrate of the mud, and the diversion electric slide drives the diversion treatment plate to push the debris to move. , cooperate with the reciprocating hydraulic cylinder to drive the reciprocating impact plate to push the elastic separation mesh plate to move up and down, use the back and forth swing to push the mud mixture to move, cooperate with elastic shaking, use vibration screening and swing separation to achieve the separation of mud and debris, through the three-stage mud mixture separation treatment, realize the step-by-step dehydration of large particles, small particles and mud, and intercept the debris to achieve continuous processing, thereby refining the mud mixture, improving the mud recovery efficiency and recovery volume, so that it can be recovered quickly and stably during excavation, reducing the impact of mud on the processing environment, and improving environmental stability.

[0043] In summary, through the cooperation of the double-jointed whole-mixing components and the multi-division external discharge components, the cooperation of excavation injection and excavation drainage, and the recovery and treatment of the reflux liquid, the cooperation of the centrifugal treatment at both ends and the two-stage screen treatment can realize the mud circulation recovery and refine the mud to improve the mud recovery rate and efficiency of mud recovery. At the same time, the cooperation of pressurized cutting and multi-stage mixing can increase the speed of mixing and mud injection, and improve the efficiency and effect of treatment.

[0079] Example: Figure 11 As shown, the present invention provides a technical solution, a method for using mud in the construction of directional drilling across a river, comprising the following steps:

[0080] S1. Excavation Preparation: Use the traction equipment to place the load-bearing processing frame 1 to the excavation position. The pressure-lifting hydraulic cylinder 203 drives the sliding linkage block 204, the coordinated processing frame 205, and the operating bottom support frame 206 to rotate and lift. The integrated double-mounted frame 202 is rotated and tilted. The positioning hydraulic cylinder 207 drives the integrated double-mounted frame 202 to move. The mud raw material is placed in the inner side of the material processing box 226. Water is injected into the inner side of the operating storage box 201 to complete the excavation preparation.

[0081] S2. Excavation process: The internal threaded compression sleeve 212 is threadedly combined with the high-pressure cutter 218, and the threaded pipe 217 is threadedly connected to the high-pressure cutter 218. The internal threaded compression sleeve 212 is rotated by the motor 214 and the belt transmission box 213. The mud is extracted through the external pipe rack 230, the injection pipe rack 231 and the booster pump 232. The water injection buffer box 215, the water inlet operating pipe 216, the electric push rod 219 and the conical flow limiter 220 are used to control the speed and pressure of the mud. The rotary cutting process is used to achieve soil excavation.

[0082] S3. Liquid recovery: The mixed liquid discharged from the excavation is sprayed back to the inside of the centralized collection box 315. The mixed liquid is driven by the reflux pipe rack 319 and the reflux pump 320 to flow back into the diversion treatment box 301. It is separated by the diversion mesh plate 302. The hydrocyclone 234 and the horizontal centrifuge 239 are used to centrifuge the mud. The reflux injection pipe 242, the drainage treatment pipe 313 and the drainage pump 314 drive the mud back to achieve mud reflux recovery.

[0083] S4. Circulation excavation: The slurry is returned through the hydrocyclone 234 and the horizontal centrifuge 239, the slurry and the slurry treatment material are mixed by the multi-chamber mixing box 225 and the material treatment box 226, the slurry is stirred by the stirring motor 228 and the stirring and pushing rack 229, and the slurry is utilized and processed by the external pipe rack 230, the injection pipe rack 231 and the booster pump 232 to realize continuous circulation excavation.

[0084] The working principle and use process of the present invention are as follows: when directional drilling is carried out across a river channel, the staff uses the transport and traction equipment to move the load-bearing processing frame 1 to the drilling position, uses the external water storage equipment to inject water into the operation storage box 201, and the pressure-lifting hydraulic cylinder 203 drives the sliding linkage block 204 to move along the load-bearing processing frame 1. The sliding linkage block 204 drives the matching processing frame 205 to rotate and rise. While the matching processing frame 205 rotates, it pushes the operating bottom support frame 206 to rotate along the operation storage box 201, so that the operating bottom support frame 206 and the integrated double matching frame 202 rotate and tilt, so that the equipment can quickly carry out the processing, adjust the operating angle of the equipment to ensure the stability of the excavation processing, and insert the centralized collection box 315 into the excavation water outlet position to realize the excavation pre-processing;

[0085] The integrated double-mounted frame 202 is driven by the counter-position hydraulic cylinder 207 to move along the operating bottom support frame 206, and the integrated double-mounted frame 202 is moved to the operating position, and the high-pressure cutter 218 is inserted into the inner side of the internal thread pressing sleeve 212, and the high-pressure cutter 218 is connected to the internal thread pressing sleeve 212 by means of a thread, and the hydraulic motor 208 drives the moving screw rod 209 to rotate along the integrated double-mounted frame 202, and a group of moving screw rods 209 drives the load-bearing limit sleeve 211 to move and fit to the side end of the integrated double-mounted frame 202, and the other group of moving screw rods 209 drives the pressing operating frame 210 and the internal thread pressing sleeve 212 to push the high-pressure cutter 218 into the ground, and cooperates with the motor 21 4 and the belt transmission box 213 drive the internal thread pressing sleeve 212 to rotate, and the high-pressure cutter 218 is inserted into the soil by rotating and pressing. After the insertion is completed, the high-pressure cutter 218 is loosened by rotating the equipment in the opposite direction. At this time, the movable screw rod 209 drives the pressing operation frame 210 to reset, and the entry threaded pipe 217 is placed on the side end of the internal thread pressing sleeve 212 by the external lifting equipment, and is fixed and combined again by rotation and thread. The entry threaded pipe 217 and the high-pressure cutter 218 are combined by thread, and the water inlet operation pipe 216 is inserted into the inner side of the entry threaded pipe 217. When drilling and excavating, the above operations are fully performed to realize continuous combined excavation processing;

[0086] The water in the operation storage box 201 is extracted by the booster pump 232 and the injection pipe rack 231. According to the soil conditions, the injection pipe rack 231 is opened through the limiting valve 233, and the required thickener, base mud, fluid loss additive, lubricant, plugging agent, etc. are respectively added into the inner side of the material processing box 226. The limiting valve 233 opens the feeding operation pipe 227, and the stirring motor 228 drives the stirring pushing rack 229 to push the required materials along the chamber of the material processing box 226 along the feeding operation pipe 227 into the inner side of the multi-cavity mixing box 225. The water enters the inner side of the multi-cavity mixing box 225 along the injection pipe rack 231, and the stirring motor The machine 228 drives the mixing and pushing rack 229 to push the water and material to mix, adjust the properties of the mud, and the booster pump 232 and the external pipe rack 230 extract the mud in the multi-cavity mixing box 225, and inject the mud into the inner side of the water injection buffer box 215 along the multi-cavity mixing box 225. The inserted electric push rod 219 drives the conical flow limiter 220 along the inner side of the water inlet operating pipe 216, and the mud is injected into the threaded pipe 217 and the high-pressure cutter 218 along the water injection buffer box 215 and the water inlet operating pipe 216. The mud is then ejected by the high-pressure cutter 218 to perform hydraulic cutting on the soil, realizing continuous cutting processing and ensuring the cutting speed;

[0087] When water is inflowing, the pressure of the mud injected into the pipe is gradually lengthened, and the mud pushes the porous outer spray frame 223. The porous outer spray frame 223 enters the threaded pipe 217 and separates from the fixed assembly frame 221. At this time, the spring telescopic rod 222 is stretched, and the pressure sensor 224 is separated from the fixed assembly frame 221. The pressure is detected by the pressure sensor 224. When the internal mud pressure decreases, the multi-chamber mixing and dual-pump injection processing are carried out simultaneously, and the water inlet speed of the water inlet operation pipe 216 is adjusted by the conical flow limiting block 220. This ensures the stability of the mud pressure and the speed of mud injection when excavating at different distances, thereby improving the excavation speed and ensuring the stability of excavation.

[0088] During excavation, the mud mixed with the debris generated by the excavation flows into the threaded pipe 217 and the high-pressure cutter 218 and is discharged in the reverse direction. The discharged mud is sprayed into the inner side of the centralized collection box 315 along the excavation hole. The mixed liquid in the centralized collection box 315 is extracted by the reflux pump 320 and the reflux pipe rack 319. The mixed liquid is sprayed into the inner side of the diversion treatment box 301 along the reflux pipe rack 319. The mixed liquid is sprayed into the position of the diversion mesh plate 302. The mixed liquid is separated and processed by the diversion mesh plate 302, and the gravel and large-particle soil impurities are intercepted and processed. The external electric slide rail 303 drives the external slag discharge plate 304 to push the gravel to move, thereby realizing steady filtration processing.

[0089] After the preliminary treatment, the mixed liquid enters the diversion treatment box 301, and the mixed liquid in the diversion treatment box 301 is extracted by the injection operation pipe 235 and the injection pump 241. The mixed liquid is injected into the hydrocyclone 234 along the injection operation pipe 235, and the hydrocyclone 234 performs centrifugal separation on the mixed liquid. The coarse particle impurities are discharged downward along the hydrocyclone 234 into the inner side of the impact separation box 305, and the fine particles and mud are sprayed into the inner side of the relay storage box 237 along the external overflow pipe 236. The mud in the relay storage box 237 is extracted by the injection operation pipe 240 and the injection pump 241. The mud flows along the The water enters the operating pipe 240 and is injected into the horizontal centrifuge 239. The horizontal centrifuge 239 drives the mud to undergo centrifugal separation. The separated water is injected back into the operating storage box 201 along the extrapolation limiting frame 238 and the reflux injection pipe 242. The coarse mud and soil fall into the impact separation box 305 along the extrapolation limiting frame 238. The double centrifuge is combined with multi-stage interception filtration to separate the gravel and soil in the mud, and separate the mud from the waste residue. The double centrifuge increases the speed, ensuring the steady operation of the mud separation and the speed of the liquid reflux, thereby improving the processing efficiency.

[0090] The debris mixed with mud separated by centrifugation falls to the inside of the impact separation box 305, and the mud and debris both fall to the top of the elastic separation mesh plate 306. The diversion electric slide 307 drives the diversion processing plate 308 to push the debris to move, so as to avoid the debris concentration affecting the separation efficiency of the elastic separation mesh plate 306. The reciprocating hydraulic cylinder 309 drives the reciprocating impact plate 310 to push the elastic separation mesh plate 306 up and down to separate the debris from the mud. The mud drips along the elastic separation mesh plate 306 to the inside of the impact separation box 305, and the outgoing electric slide 311 drives the outgoing sealing plate 312 along the impact separation box 305 moves, the diversion electric slide 307 drives the diversion processing plate 308 to push the slag to move along the impact separation box 305 and discharge it outside, realizing steady slag discharge processing, the drainage processing pipe 313 and the drainage pump 314 extract the mud in the impact separation box 305, and inject it into the inside of the operation storage box 201, realizing mud reflux processing, the external discharge hydraulic cylinder 317 drives the external discharge slag cleaning plate 318 to drive the slag remaining in the centralized collection box 315 to move, and the slag pushes the slag discharge processing plate 316, thereby opening the centralized collection box 315, and the slag is discharged outside, ensuring steady recovery and slag cleaning processing.
