Description

Technical Field

[0001] The invention relates to the technical field of pile foundation hole-forming equipment, in particular to a beaded cave new stratum pile foundation rapid hole-forming construction device. Background Art

[0002] Beaded caves refer to multiple caves of different sizes connected in series to form an overall cave system. This type of cave is usually a new stratum formed by groundwater dissolving in rocks. In the process of developing cave attractions, piling is required to support the construction facilities and terrain environment of the new stratum, thereby improving the stability of the geology and ensuring the stability and safety of the facilities. In order to facilitate the construction and installation of pile foundations, pile foundation rapid drilling equipment is usually required to drill and excavate the stratum, which is beneficial to improve the efficiency of the project while ensuring the safety and stability of the project.

[0003] Since the rock layers in the caves are mostly calcium carbonate rock layers, when the pile foundation is quickly drilled, the calcium carbonate rock layers are loose and have many gaps. Therefore, the pile foundation hole wall needs to be fixed during drilling to prevent the hole from collapsing. The existing methods for fixing the inner wall of the hole are mostly to set up anchor structures, grouting reinforcement or casing support. However, some of the existing methods, when reinforcing the inner wall of the pile foundation hole, the grouting reinforcement method drills holes around the required pile foundation drilling hole and fills the solidifying material, which not only increases the construction time and reduces the work efficiency, but also the anchoring and casing methods reduce the work efficiency by cutting and selecting the matching support structure according to actual needs when installing support structures such as support nets and pipe sleeves, and it is not convenient to install and use the support structure.

[0004] Therefore, a rapid hole-forming construction device for pile foundation in new stratum of beaded cave is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a beaded cave new stratum pile foundation rapid hole construction device to solve the problem that the grouting type reinforcement method proposed in the above background technology not only increases the construction time and reduces the work efficiency by drilling holes around the required pile foundation holes and filling them with solidifying materials, but also the anchoring and casing type methods reduce the work efficiency by cutting and selecting matching support structures according to actual needs when installing support nets and pipe sleeves, and are inconvenient for the installation and use of support structures.

[0019] The present invention provides a beaded cave new stratum pile foundation rapid hole construction device, which has the following technical points and beneficial effects:

[0020] 1. The present invention designs devices such as a tamping plate, a fixed block and a closing plate. The closing plate is set to be tilted and opened and closed under centrifugal force, and the solvent is shoveled into the drain. The solvent is transported to the connecting pipe in the cavity above the grinding drill through the drain, and flows into the cavity from the diversion hole. At this time, the heated solvent in the cavity is thrown out through the injection hole under centrifugal force to combine with the crushed stone powder transported in the diversion hole, and the mixture of the solvent and the rock powder is thrown to the inner wall of the hole under directional rotation by the fixed block. The mixture of the calcium carbonate rock powder and the solvent is vibrated, infiltrated and compacted in the gap in the inner wall of the hole by the tamping plate, so as to reinforce the inner wall of the hole, thereby improving the work efficiency of the inner wall processing of the pile foundation hole.

[0021] 2. The present invention designs devices such as injection holes, telescopic vibration rods and screening holes. When the hole is drilled, the rotation rate is increased due to the small resistance encountered when the drilling drill is taken out, thereby increasing the distance that the telescopic vibration rod extends the tamping plate. At this time, the tamping plate is quickly rotated and rubbed against the inner wall of the hole as the drilling drill is taken out, thereby further improving the tamping effect of the inner wall of the hole and the flatness of the inner wall of the hole. At the same time, the screening holes screen and discharge smaller rock fragments, and then the solvent is sprayed onto the inner wall surface of the hole under the rotation of the grinding drill to improve the reinforcement effect.

[0022] 3. The present invention designs flow channels, connecting pipes, flow guides and other devices. Since the grinding drill and the crushing drill are provided with flow channels and connected with the connecting pipes, the solvent in the flow channel can cool down the grinding drill and the crushing drill when they are rotated to form holes, so as to prevent the equipment from being overheated and deformed and damaged when the pile foundation is rotated to form holes. At the same time, the solvent is heated by heat exchange in the flow channel, and the heated solvent is combined with the crushed stone powder under centrifugal force, thereby improving the solidification efficiency of the solvent and the rock powder.

DETAILED DESCRIPTION

[0036] 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.

[0037] See also Figures 1 to 12 The present invention provides a technical solution for a beaded cave new stratum pile foundation rapid hole construction device:

[0038] A beaded cave new stratum pile foundation rapid hole construction device, comprising a hole-forming machine 12 and a hole-forming drill 14 arranged at one end of the hole-forming machine 12, the hole-forming drill 14 comprising a grinding drill 16 and a crushing drill 17, a plurality of tamping plates 1401 are arranged around one side of the hole-forming drill 14, a telescopic vibration rod 1403 is fixedly connected to the inner side of the tamping plate 1401, and the tamping plate 1401 is movably connected to the hole-forming drill 14 through the telescopic vibration rod 1403, a flow hole 1404 is arranged in the telescopic vibration rod 1403, and the telescopic vibration rod 1403 is connected to the hole-forming drill 14 through the flow hole 1404;

[0039] A grinding drill 16 is fixedly connected to the bottom of the hole forming drill 14. A plurality of guide grooves 1601 are evenly spaced and penetrated inside the grinding drill 16. A spray hole 1602 is correspondingly provided above the guide groove 1601. A flow channel is provided inside the grinding drill 16 and the crushing drill 17. A guide hole 1603 is provided inside the spray hole 1602, and the guide hole 1603 is connected to the flow channel.

[0040] A flow diverter 18 is fixedly installed on the inner wall of the hole drill 14, a rotating shaft 1802 is embedded on one side of the flow diverter 18, and a torsion spring is provided on the inner side of the rotating shaft 1802, a closing plate 1801 is fixedly connected to one side of the rotating shaft 1802, and the closing plate 1801 is movably connected to the flow diverter 18 through the rotating shaft 1802.

[0041] As an embodiment of the present invention, Figures 5 to 12 As shown, a cavity is provided above the grinding drill 16, and the injection hole 1602 is through-set with the cavity, a connecting pipe is provided in the middle of the cavity, and the connecting pipe is through-connected with the flow channel, a plurality of crushing blades 1604 are fixedly installed at equal intervals below the grinding drill 16, a fixing block 1605 is provided on one side of the injection hole 1602, and the fixing block 1605 is fixedly connected with the grinding drill 16, and a crushing drill 17 is fixedly installed below the middle of the grinding drill 16;

[0042] During operation, the grinding drill 16 and the crushing drill 17 are driven by the hole forming drill 14 to perform a rotating hole forming operation. The operation of the crushing drill 17 first crushes the calcium carbonate rock below, and then the crushing blade 1604 on the grinding drill 16 further crushes the crushed rock into crushed stone powder. Since the grinding drill 16 is inclined below and the guide hole 1603 is arranged through the inclined surface, the rotation of the grinding drill 16 generates a negative pressure suction force of the gas above the guide hole 1603, thereby transporting the smaller powder from the bottom of the guide hole 1603 to the top for use;

[0043] When there are many gaps in the unstable area of ​​the calcium carbonate rock layer, the friction resistance of the crushing drill 17 and the grinding drill 16 on the drilling drill 14 is small, thereby increasing the rotation speed of the drilling drill 14 and the grinding drill 16. At this time, the centrifugal force on the closing plate 1801 in the drilling drill 14 in the flow diverter 18 increases. Since the speed at which the solvent rotates in the drilling drill 14 under the centrifugal force is lower than the rotation speed of the drilling drill 14, and the closing plate 1801 is connected to the flow diverter 18 through the rotating shaft 1802 and is inclined to open and close, the solvent is then drawn into the flow diverter 18 through the closing plate 1801. At this time, the solvent is transported to the connecting pipe in the cavity above the grinding drill 16 through the flow diverter 18. Since the grinding drill 16 and the crushing drill 17 are provided with a flow channel connected with the connecting pipe, the solvent is cooled in the flow channel when the grinding drill 16 and the crushing drill 17 are rotated to form a hole, and the solvent is heated by heat exchange in the flow channel, and then flows into the cavity from the guide hole 1603 under the circulation of the solvent. At this time, the heated solvent in the cavity is thrown out through the injection hole 1602 under the centrifugal force to combine with the crushed stone powder transported in the guide hole 1603, and the mixture of the solvent and the rock powder is thrown to the inner wall of the hole under the directional rotation through the fixed block 1605, thereby improving the solidification efficiency of the solvent and the rock powder, so as to reinforce the inner wall of the hole;

[0044] When the pile foundation is drilled and the drilling drill 14 is taken out, the screening holes 1204 screen out smaller rock fragments, and then the solvent is sprayed onto the inner wall surface of the hole under the rotation of the grinding drill 16 to improve the reinforcement effect, wherein the solvent is a large class of chemical solutions that combine with calcium carbonate to produce a solidification effect.

[0045] As an embodiment of the present invention, Figures 7 to 12 As shown, a skin cloth 1402 is fitted on one side of the tamping plate 1401, and the skin cloth 1402 is fitted with the hole drill 14, a rotating column 15 is fixedly installed above the hole drill 14, and the rotating column 15 and the hole drill 14 are through-set, and a guide plate 1501 is fixedly installed around the outer side of the rotating column 15 at equal intervals, and a hole drill 12 is nested on the outer side of the rotating column 15;

[0046] During operation, the rotating column 15 drives the drill 14 to rotate so as to perform a rotary drilling operation on the karst rock formation. When the drill 14 rotates downward to drill a hole, the guide groove is provided on the drill 14, and the rock fragments are transported upward to the guide plate 1501 to discharge the excess rock fragments. The telescopic vibration rod 1403 is thrown outward for a certain distance under the centrifugal force generated by the rapid rotation of the drill 14, and then the tamping plate 1401 is fitted with the inner wall of the hole. Secondly, the rotation of the drill 14 flows the solvent into the flow hole 1404 to improve the contact with the hole. The compacting plate 1401 is used to compact the mixture of calcium carbonate rock powder and solvent into the gaps in the inner wall of the hole through the vibration transmission generated by the crushing drill 17 and the grinding drill 16 when rotating to form a hole, so as to reinforce the gaps and unstable areas in the inner wall of the hole during the rotation to form a hole. Since the covering cloth 1402 is compacted with the hole forming drill 14 and the compacting plate 1401, it prevents debris from entering the space formed by the hole forming drill 14 and the compacting plate 1401, and facilitates the replacement and use later;

[0047] When the hole is drilled, the resistance encountered in removing the hole drill 14 is small, thereby increasing the rotation rate of the hole drill 14 and increasing the distance that the telescopic vibration rod 1403 extends the tamping plate 1401. At this time, the tamping plate 1401 is taken out with the hole drill 14 to quickly rotate and rub the inner wall of the hole, further improving the tamping effect of the inner wall of the hole and improving the flatness of the inner wall of the hole.

[0048] As an embodiment of the present invention, Figures 2 to 5 As shown, a discharge sleeve 1201 is fixedly installed above the hole forming machine 12, and an opening is provided on one side of the discharge sleeve 1201. A driving machine 13 is fixedly installed above the discharge sleeve 1201, and a differential is provided on one side of the driving machine 13. The rotating column 15 passes through the discharge sleeve 1201 and is connected to the differential for transmission. A limit plate 1203 is fixedly installed at one end of the discharge sleeve 1201, and the rotating column 15 and the limit plate 1203 are engaged and movable. A screening sleeve 1202 is provided on one side of the hole drill 14, a screening hole 1204 is provided around one side of the screening sleeve 1202, and the screening hole 1204 and the screening sleeve 1202 are arranged through each other, a sliding plate 1205 is fixedly installed on one side of the hole forming machine 12, a limiting sleeve 1206 is fixedly installed on one side of the sliding plate 1205, a punching frame 9 is provided on one side of the hole forming machine 12, and the hole forming machine 12 is movably connected to the punching frame 9 through the sliding plate 1205;

[0049] The hole forming machine 12 includes a discharge sleeve 1201, a screening sleeve 1202, a limiting plate 1203, screening holes 1204, a sliding plate 1205 and a limiting sleeve 1206;

[0050] During operation, the driving machine 13 on the hole forming machine 12 provides power to the rotating column 15 for directional rotation. The fixed rotation of the rotating column 15 causes the guide plate 1501 on the rotating column 15 to transport the rock fragments to the discharge sleeve 1201. Since an opening is provided on one side of the discharge sleeve 1201, when discharging the rock fragments, a guide plate or a collection bag is installed at the opening to collect and clean the rock fragments. When the guide plate 1501 transports the rock fragments, the smaller rocks are separated by the screening holes 1204 on the screening sleeve 1202. The crushed materials are screened and discharged for use in combination with solvents. Secondly, the rotating column 15 is interlocked and limited by the limit plate 1203 to improve the stability of the rotating column 15 when rotating to form holes. When the hole drill 12 goes deeper into the rock ground, the sliding plate 1205 slides on the punching frame 9 to control the penetration distance. At the same time, the guide tube 1101 is nested by the limit sleeve 1206 to ensure the stability of the guide tube 1101 when transporting solvent to the rotating column 15, and then the solvent is transported to the hole drill 14 for use through the rotating column 15.

[0051] As an embodiment of the present invention, Figures 1 to 4 As shown, a support plate 10 is installed on the top of the punching frame 9, and the support plate 10 and the hole forming machine 12 are arranged in a close support. A docking pump 11 is fixedly installed on one side of the punching frame 9, and a guide pipe 1101 is installed through one side of the docking pump 11, and the guide pipe 1101 is connected to the rotating column 15 through a differential. A pile foundation punching vehicle 1 is provided below the punching frame 9, and a bracket 7 for supporting the punching frame 9 is fixedly installed above the pile foundation punching vehicle 1. A hydraulic telescopic rod 8 is movably installed on one side of the punching frame 9, and the hydraulic telescopic rod 8 is movably connected to the pile foundation punching vehicle 1, and the punching frame 9 is movably connected to the bracket 7 through the hydraulic telescopic rod 8;

[0052] During operation, the punching frame 9 is supported and fixed by the bracket 7 when the pile foundation drilling vehicle 1 moves, and the hole forming machine 12 is supported and fixed on the punching frame 9 by the support plate 10 and the sliding disk 1205. The solvent is transported from the guide tube 1101 to the rotating column 15 for use through the operation of the docking pump 11. When drilling, the punching frame 9 is supported on the bracket 7 and facing the ground through the operation of the hydraulic telescopic rod 8, and then the support plate 10 is removed from the punching frame 9 to facilitate the sliding disk 1205 to operate on the punching frame 9 for drilling holes.

[0053] As an embodiment of the present invention, Figures 1 to 3As shown, a buffer plate 3 is fixedly installed on one side of the pile foundation drilling vehicle 1, and a support column 2 is symmetrically fixedly installed on one side of the buffer plate 3, a docking hole 4 is provided in the middle of the buffer plate 3, and a docking pump 11 is docked with the docking hole 4 through the extension of a hydraulic telescopic rod 8, crawlers 6 are movably installed on both sides of the pile foundation drilling vehicle 1, and a plurality of driving wheels 101 are movably installed on both sides of the pile foundation drilling vehicle 1, and the crawlers 6 and the driving wheels 101 are transmission-connected, and a side plate 5 is provided on one side of the crawler 6, and the side plate 5 and the pile foundation drilling vehicle 1 are in an inlaid fixed connection;

[0054] During operation, the driving wheel 101 is driven to cause the crawler 6 to reciprocate and rotate on both sides of the pile foundation drilling vehicle 1, and the side plates 5 are installed on both sides of the crawler 6 for blocking protection, thereby preventing larger impurities such as gravel from entering the crawler 6 when the pile foundation drilling vehicle 1 is moving and causing damage to the equipment. Secondly, when the drilling frame 9 docks the docking pump 11 with the docking hole 4 through the operation of the hydraulic telescopic rod 8, the docking hole 4 docks with the docking pump 11 to transport the solvent loaded in the pile foundation drilling vehicle 1 to the docking pump 11 for use, and the buffer plate 3 is used to reduce the vibration of the pile foundation drilling vehicle 1 caused by the docking pump 11 and the drilling frame 9 during hole forming. During hole forming operation, the support column 2 is extended to fit the ground for support to improve stability.

[0055] Working principle: The pile foundation drilling vehicle 1 is moved by the crawler 6, and the solvent loaded in the pile foundation drilling vehicle 1 is transported from the guide pipe 1101 to the rotating column 15 for use through the docking hole 4 and the docking pump 11. During operation, the drilling frame 9 is supported on the bracket 7 and facing the ground through the operation of the hydraulic telescopic rod 8, and then the support plate 10 is removed from the drilling frame 9 to facilitate the sliding plate 1205 to form holes on the drilling frame 9. The buffer plate 3 is used to reduce the vibration of the pile foundation drilling vehicle 1, and the support column 2 is used to improve stability;

[0056] When pile foundation drilling construction is carried out, the driving machine 13 provides power for the rotating column 15 to rotate in a directional manner, and the rock fragments are transported to the discharge sleeve 1201 through the guide plate 1501 on the rotating column 15, and then the rock fragments are collected and cleaned. When the guide plate 1501 transports the rock fragments, the smaller rock fragments are screened and discharged through the screening holes 1204 so as to be used in combination with the solvent. Secondly, the rotating column 15 is engaged and limited by the limit plate 1203 to improve stability. When the drilling machine 12 goes deeper into the rock ground, the sliding plate 1205 slides on the drilling frame 9 to control the penetration distance, and the solvent is transported to the drilling drill 14 for use by the rotating column 15 through the guide pipe 1101;

[0057] The hole-forming drill 14 is driven to rotate by the rotating column 15, and the grinding drill 16 and the crushing drill 17 are driven by the hole-forming drill 14 to perform a rotating hole-forming operation. The operation of the crushing drill 17 first crushes the calcium carbonate rock below, and then the crushing blade 1604 on the grinding drill 16 further crushes the crushed rock into crushed stone powder, so that the smaller powder is transported from the bottom of the guide hole 1603 to the top for use;

[0058] When there are many gaps in the unstable area of ​​the calcium carbonate rock layer, the friction resistance of the crushing drill 17 and the grinding drill 16 on the hole drill 14 is small, thereby increasing the rotation rate of the hole drill 14 and the grinding drill 16. At this time, the centrifugal force on the closing plate 1801 in the hole drill 14 in the diverter 18 increases. The closing plate 1801 is connected to the diverter 18 through the rotating shaft 1802 and is tilted and opened and closed under the centrifugal force. The solvent is sifted into the diverter 18 through the closing plate 1801 and transported to the connecting pipe in the cavity above the grinding drill 16, so that the solvent in the flow channel is cooled when the grinding drill 16 and the crushing drill 17 rotate to form a hole. At the same time, the solvent is heated in the flow channel, and then circulates to the cavity. The heated solvent passes through the injection hole 1 under the centrifugal force. 602 is thrown out to combine with the crushed stone powder transported in the guide hole 1603, and the mixture of the solvent and the rock powder is thrown into the gap of the inner wall of the hole through the fixed block 1605 under directional rotation, and the compacting plate 1401 is fitted with the inner wall of the hole after being thrown outward for a certain distance under centrifugal force by the telescopic vibration rod 1403. Secondly, the solvent is poured into the flow hole 1404 through the rotation of the hole-forming drill 14 to improve the fitting effect with the inner wall of the hole and generate impact force. At the same time, the vibration generated by the crushing drill 17 and the grinding drill 16 when rotating to form a hole is transmitted, so that the compacting plate 1401 vibrates and penetrates and compacts the mixture of the calcium carbonate rock powder and the solvent into the gap in the inner wall of the hole, so as to reinforce the gap and unstable area in the inner wall of the hole during the rotation to form a hole;

[0059] When the hole is drilled, the resistance encountered in removing the drilling drill 14 is small, thereby increasing the rotation rate of the drilling drill 14 and increasing the distance that the telescopic vibration rod 1403 extends the tamping plate 1401. At this time, the tamping plate 1401 is taken out with the drilling drill 14 to quickly rotate and rub the inner wall of the hole, further improving the tamping effect of the inner wall of the hole and the flatness of the inner wall of the hole. At the same time, the screening holes 1204 screen out smaller rock fragments, and then the solvent is sprayed onto the inner wall surface of the hole under the rotation of the grinding drill 16 to improve the reinforcement effect.
