Description

Technical Field

[0001] The invention belongs to the field of civil construction, in particular to a civil construction deep foundation construction process and a deep excavation device thereof. Background Art

[0002] With the development of the construction industry, the height of buildings is getting higher and higher, and the required foundations have to be inserted deeper and deeper, so special deep pit digging equipment is needed to dig pits.

[0003] A Chinese patent with publication number CN105986760A discloses a crawler auger, comprising a crawler body, a hydraulic motor, a cross-linked shaft, a drill rod and an auger bit. The hydraulic motor and the cross-linked shaft are arranged at the lower part of the two arms of the crawler body, and a hydraulic motor is provided on one side of the crawler body. The crawler auger has the characteristics of fast movement, lightness and low cost, which is conducive to on-site bored pile drilling, can quickly complete production tasks, speed up work efficiency, save costs, reasonably use labor and improve production efficiency.

[0004] The existing technology still has some shortcomings. Since the auger required for deep foundation construction is often long, it is inconvenient to clean the soil attached to the outside of the auger after work. Over time, the soil will have too much adhesion after drying, making it difficult to remove.

[0005] To this end, the present invention provides a civil engineering deep foundation construction process and a deep excavation device thereof. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is: the civil engineering deep foundation construction process of the present invention is specifically:

[0008] S1: Survey the location where the foundation needs to be built, accurately locate it, use a driving vehicle to transport the auger to the designated location, and start the auger to perform deep foundation drilling after the positioning is completed;

[0009] S2: After the operation is completed, the auger is pulled out upwards, and the cleaning block is sleeved on the outer side of the bottom end of the auger. The cleaning block is driven by the driving wheel to spirally climb on the outer side of the auger;

[0010] S3: The impact block on the outside of the cleaning block is used to impact the surface of the auger. At the same time, the cleaning piece on the outside of the cleaning block is set to discharge the loose soil after the impact to the outside of the auger. During the cleaning process, personnel are prohibited from entering within ten meters of the auger.

[0011] Since the auger required for deep foundation construction is often long, it is inconvenient to clean the soil attached to the outside of the auger after work. Over time, the soil will have too much adhesion after drying, making it difficult to remove. By setting a cleaning block that can crawl autonomously, you only need to place the cleaning block on the auger after the work is completed, and the soil on the outside of the auger can be removed as the cleaning block climbs, making the cleaning process easy and convenient. When the auger needs to be used, the cleaning block can be removed, which will not affect the normal work of the auger.

[0012] A deep excavation device for civil engineering deep foundation construction technology, the device is suitable for the civil engineering deep foundation construction technology described above, one end of the driving vehicle is provided with an extension arm, one side of the auger is fixedly connected to the extension arm of the driving vehicle, there are two groups of driving wheels, the two groups of driving wheels are arranged in parallel, one end of the driving wheel is fixedly installed with a driving motor, the driving motor is fixedly connected to a cleaning block, the driving wheel and the cleaning block are arranged at an angle, when the auger is finished working, the middle part of the cleaning block is engaged with the blade of the auger, the driving wheel is started, and the inclined structure of the driving wheel is set, so that when the driving wheel is crawling upward, the cleaning block is in a state of moving upward and inward at the same time, so that the driving wheel can always fit closely with the auger, so that the cleaning process of the cleaning sheet and the impact block can proceed smoothly.

[0013] Preferably, an inner groove is provided at the top of the cleaning block, and a half gear one is rotatably connected to the inner side of the inner groove, a swing block is fixedly installed on the outer side of the half gear one, and the outer side of the swing block is fixedly connected to the impact block. A power assembly is provided on the outer side of the half gear one, and the power assembly can drive the swing block to swing repeatedly, so that the impact block can repeatedly impact the outer side of the auger, which can effectively reduce the adhesion between the soil and the auger, and then cooperate with the effect of the cleaning sheet to easily remove the soil on the outer side of the auger, thereby improving the removal effect.

[0014] Preferably, the power assembly includes half gear two, one end of which is fixedly mounted with a servo motor, and half gear two is meshed with half gear one. A piston rod is fixedly mounted on the outer side of the swing block, and a piston tube is fixedly mounted on the inner side of the inner groove. The piston tube and the piston rod are both arranged in an arc shape, and a spring is fixedly connected between the piston rod and the piston tube. The servo motor is started to drive half gear two to rotate. Through the arrangement of half gear two and half gear one, only half a circle of half gear two can drive half gear one to rotate, so that the swing block can hit downward quickly. The reaction force generated after the collision plus the effect of the spring can make the swing block return to the upward state, so that it can perform the next wave of impact. Through this arrangement, the repeated swinging effect of the swing block is effectively achieved, and there is no need to set up multiple groups of control components to achieve the swing of the swing block.

Combined with the structural arrangement of the cleaning sheets, the cleaned soil will be separated to the outside under the action of extrusion, so that the cleaned soil will not accumulate on the outside of the cleaning sheets, but move outward along the cleaning sheets, thereby ensuring the subsequent cleaning effect, and at the same time, the subsequent nozzles can output airflow outward under the operation of the air supply assembly, so that the remaining uncleaned residues can be blown out.

[0016] Preferably, the air supply assembly includes a one-way transmission tube, one end of the one-way transmission tube is connected to a plurality of groups of nozzles, the other end of the one-way transmission tube is connected to the inner side of a piston tube, a one-way valve is fixedly mounted on one side of the piston tube, the other end of the one-way valve is connected to the outside, and as the swing block swings, the piston rod is continuously squeezed, and with the arrangement of the one-way transmission tube and the one-way valve, the one-way valve is used to intake air inward, while the one-way transmission tube exhausts air outward, thereby effectively utilizing the swinging effect of the swing block and transferring excess power into the output of air pressure, thereby realizing the jet operation of the nozzle without consuming other energy.

[0017] Preferably, the impact block is arranged in an L shape, a plurality of groups of ventilation grooves are opened on the outer side of the impact block, and two groups of symmetrically arranged drainage grooves are opened on one side of the impact block. The drainage grooves are arranged in an arc shape, which, together with the ventilation grooves opened on the impact block, can effectively reduce the air resistance of the impact block when it falls, so that the impact block can quickly impact the auger, and the setting of the two groups of drainage grooves makes the wind resistance of the impact block when it falls also spread to both sides along the drainage grooves, further reducing the wind resistance, thereby ensuring the impact effect.

[0018] Preferably, an amplification block is fixedly installed at one end of the impact block, and the amplification block includes a connecting seat, and the bottom end of the connecting seat is rotatably connected to two groups of symmetrically arranged opening covers, the bottom end of the opening cover is smoothly arranged, and a magnet block is fixedly installed at the bottom end of the opening cover. With the impact of the impact block, in cooperation with the two rotating opening covers in the amplification block, the two opening covers will separate to both sides during the impact, and the amplification block will continue to move downward as a whole, and the two opened opening covers will push the soil on the outside of the auger to both sides. Compared with a simple impact, not only the impact force is decomposed to reduce the damage to the auger by the impact, but the augers unfolded on both sides can also increase the area of ​​the soil being pushed, so that the auger at the same place will be repeatedly pushed by the unfolded opening covers, which can further increase the effect of stripping the soil.

[0019] Preferably, a center block is fixedly installed at the bottom end of the connecting seat, and the bottom end of the center block is set in a pointed shape. The outer side of the center block and the inner side of the opening cover are fixedly connected with elastic ropes. With the setting of the center block, the soil at the impact point can be crushed emphatically, and with the setting of the elastic rope, the opening angle of the opening cover can be effectively limited, so that the sharp center block will not touch the surface of the auger, but will be suspended a few millimeters above the auger, thereby destroying the soil without damaging the auger.

[0020] Preferably, several groups of crushing blocks are rotatably connected to the outer side of the opening cover, the ends of the crushing blocks are arranged in a pointed shape, and the outer sides of the crushing blocks are arranged in a multi-angular shape. As the amplification blocks impact downward, several rotating crushing blocks will also be inserted into the soil.

At the same time, the cleaning piece 9 outside the cleaning block 3 is set to discharge the loose soil after the impact to the outside of the auger 2. During the cleaning process, personnel are prohibited from entering within ten meters of the auger 2;

[0037] Since the auger 2 required for deep foundation construction is often long, it is inconvenient to clean the soil attached to the outside of the auger 2 after work. Over time, the soil has too much adhesion after drying, making it difficult to remove. By setting a cleaning block 3 that can crawl independently, it is only necessary to place the cleaning block 3 on the auger 2 after the work is completed, and the soil on the outside of the auger 2 can be removed as the cleaning block 3 climbs, making the cleaning process easy and convenient. When the auger 2 needs to be used, the cleaning block 3 can be removed, which will not affect the normal operation of the auger 2.

During operation, when the auger 2 finishes working, the middle part of the cleaning block 3 is engaged with the blade of the auger 2, and the driving wheel 4 is started. In combination with the inclined structure of the driving wheel 4, the cleaning block 3 is in a state of moving upward and inward at the same time during the upward crawling process of the driving wheel 4, so that the driving wheel 4 can always fit closely with the auger 2, so that the cleaning process of the cleaning sheet 9 and the impact block 6 can proceed smoothly.

A power component is arranged on the outer side of the half gear 13. When working, the power component can drive the swing block 5 to swing repeatedly, so that the impact block 6 can repeatedly impact the outer side of the auger 2, which can effectively reduce the adhesion between the soil and the auger 2, and then cooperate with the effect of the cleaning sheet 9 to easily remove the soil on the outer side of the auger 2, thereby improving the removal effect.

When working, the servo motor is started to drive the half gear 2 14 to rotate. Through the arrangement of the half gear 2 14 and the half gear 1 13, only half a circle of the half gear 2 14 can drive the half gear 1 13 to rotate, so that the swing block 5 can quickly impact downward, and the reaction force generated after the impact plus the effect of the spring can allow the swing block 5 to return to the upward state, so that it can perform the next wave of impact work. Through this arrangement, the repeated swinging effect of the swing block 5 is effectively achieved, and there is no need to set multiple groups of control components to achieve the swing of the swing block 5.

[0041] like Figures 4 to 5As shown, the cleaning pieces 9 include two, the two cleaning pieces 9 are symmetrically arranged, and the cleaning pieces 9 are fixedly connected to one side of the cleaning block 3, and a plurality of groups of nozzles 7 are fixedly installed on the other side of the cleaning block 3, and an air supply assembly is arranged at one end of the nozzle 7, and the outer side of the cleaning block 3 is arranged in an arc shape, and the cleaning block 3 has a structure that is high on one side and low on the other side. When working, the structural setting of the cleaning pieces 9 is cooperated, so that the cleaned soil will be separated to the outside under the action of extrusion, so that the cleaned soil will not accumulate on the outside of the cleaning piece 9, but move outward along the cleaning piece 9, thereby ensuring the subsequent cleaning effect, and at the same time, the subsequent nozzle 7 can output airflow outward under the operation of the air supply assembly, so that the remaining uncleaned residue can be blown out.

[0042] like Figure 5 As shown, the air supply assembly includes a one-way transmission tube 12, one end of the one-way transmission tube 12 is connected to a plurality of groups of nozzles 7, and the other end of the one-way transmission tube 12 is connected to the inner side of the piston tube 10. A one-way valve is fixedly installed on one side of the piston tube 10, and the other end of the one-way valve is connected to the outside. During operation, as the swing block 5 swings, the piston rod 11 is continuously squeezed. With the arrangement of the one-way transmission tube 12 and the one-way valve, the one-way valve is used to intake air inward, while the one-way transmission tube 12 exhausts air outward, thereby effectively utilizing the swing effect of the swing block 5, transferring excess power to the output of air pressure, thereby realizing the jet operation of the nozzle 7 without consuming other energy.

[0043] like Figures 4 to 5 As shown, the impact block 6 is arranged in an L shape, and a plurality of ventilation grooves are provided on the outer side of the impact block 6. Two groups of symmetrical drainage grooves are provided on one side of the impact block 6. The drainage grooves are arranged in an arc shape. When working, the ventilation grooves provided on the impact block 6 can effectively reduce the air resistance of the impact block 6 when it falls, so that the impact block 6 can quickly impact the auger 2. The setting of the two groups of drainage grooves makes the wind resistance of the impact block 6 when it falls also spread to both sides along the drainage grooves, further reducing the wind resistance, thereby ensuring the impact effect.

The bottom end of the connecting seat 15 is rotatably connected with two groups of symmetrically arranged opening covers 16. The bottom end of the opening cover 16 is arranged in a smooth shape, and the bottom end of the opening cover 16 is fixedly installed with a magnet block 19. During operation, with the impact of the impact block 6, in cooperation with the two rotating opening covers 16 in the amplification block 8, during the impact, the two opening covers 16 will separate to both sides, and at the same time, the amplification block 8 will continue to move downward as a whole, and the two opened opening covers 16 will push the soil on the outside of the auger 2 to both sides. Compared with a simple impact, not only the impact force is decomposed to reduce the damage to the auger 2 caused by the impact, but also the auger 2 unfolded on both sides can increase the area of ​​the soil being pushed, so that the auger 2 at the same place will be repeatedly pushed by the unfolded opening cover 16, which can further increase the effect of stripping the soil.

[0045] like Figure 6 As shown, a center block 17 is fixedly installed at the bottom end of the connecting seat 15, and the bottom end of the center block 17 is set in a pointed shape. The outer side of the center block 17 and the inner side of the opening cover 16 are fixedly connected with an elastic rope 18. When working, with the setting of the center block 17, the soil at the impact point can be crushed emphatically, and with the setting of the elastic rope 18, the opening angle of the opening cover 16 can be effectively limited, so that the sharp center block 17 will not touch the surface of the auger 2, but will be suspended a few millimeters above the auger 2, thereby destroying the soil without damaging the auger 2. Example

[0046] like Figure 6 As shown, compared with Example 1, another implementation of the present invention is: a plurality of groups of crushing blocks 20 are rotatably connected to the outer side of the opening cover 16, the ends of the crushing blocks 20 are arranged in a pointed shape, and the outer sides of the crushing blocks 20 are arranged in a multi-angular shape. When working, as the amplification block 8 impacts downward, a plurality of rotating crushing blocks 20 will also be inserted into the soil, and then in the opening process of the opening cover 16, the crushing blocks 20 will also cut the soil, further improving the effect of removing the soil.

[0047] During operation, when the auger 2 has finished working, the middle part of the cleaning block 3 is engaged with the blade of the auger 2, and the driving wheel 4 is started. With the inclined structure of the driving wheel 4, the cleaning block 3 is in a state of moving upward and inward at the same time during the upward crawling process of the driving wheel 4, so that the driving wheel 4 can always fit closely with the auger 2, so that the cleaning process of the cleaning piece 9 and the impact block 6 can proceed smoothly; during operation, the power component can drive the swing block 5 to swing repeatedly, so that the impact block 6 can repeatedly impact the outside of the auger 2, which can effectively reduce the adhesion between the soil and the auger 2, and then with the effect of the cleaning piece 9, the soil on the outside of the auger 2 can be easily removed, thereby improving the removal effect; during operation, start The servo motor drives the half gear 2 14 to rotate. Through the arrangement of the half gear 2 14 and the half gear 1 13, only half a circle of the half gear 2 14 can drive the half gear 1 13 to rotate, so that the swing block 5 can quickly impact downward. The reaction force generated after the impact plus the effect of the spring can return the swing block 5 to the upward state, so that it can perform the next wave of impact. Through this arrangement, the repeated swing effect of the swing block 5 is effectively achieved, and there is no need to set up multiple groups of control components to achieve the swing of the swing block 5; when working, the structural arrangement of the cleaning sheet 9 is coordinated, so that the cleaned soil will be separated to the outside under the action of squeezing, so that the cleaned soil will not accumulate on the outside of the cleaning sheet 9, but move outward along the cleaning sheet 9, The subsequent cleaning effect is guaranteed, and at the same time, the subsequent nozzle 7 can output air flow to the outside under the operation of the air supply component, so that the remaining uncleaned residue can be blown out; when working, with the swing of the swing block 5, the piston rod 11 will be continuously squeezed, and the one-way transmission pipe 12 and the one-way valve will be arranged. The one-way valve is used to take in air inward, and the one-way transmission pipe 12 is used to exhaust air outward, thereby effectively utilizing the swing effect of the swing block 5, transferring the excess power to the output of air pressure, so that the jet work of the nozzle 7 can be realized without consuming other energy; when working, the ventilation grooves on the impact block 6 can effectively reduce the air resistance when the impact block 6 falls, so that the impact block 6 can quickly impact the auger 2, and the two sets of guide The arrangement of the flow channel allows the wind resistance of the impact block 6 to spread to both sides along the drainage channel when it falls, further reducing the wind resistance and thus ensuring the impact effect; during operation, as the impact block 6 impacts, in cooperation with the two rotating open covers 16 in the amplification block 8, the two open covers 16 will separate to both sides during the impact, while the amplification block 8 will continue to move downward as a whole, and the two opened open covers 16 will push the soil on the outside of the auger 2 to both sides. Compared with a simple impact, not only the impact force is decomposed to reduce the damage to the auger 2 caused by the impact, but also the auger 2 unfolded on both sides can increase the area of ​​the soil being pushed, so that the auger 2 at the same location will be repeatedly pushed by the unfolded open covers 16, which can further increase the effect of stripping the soil;When working, with the setting of the center block 17, the soil at the impact point can be crushed intensively, and with the setting of the elastic rope 18, the opening angle of the opening cover 16 can be effectively limited, so that the sharp center block 17 will not touch the surface of the auger 2, but will be suspended a few millimeters above the auger 2, thereby destroying the soil without damaging the auger 2; when working, with the downward impact of the amplification block 8, several rotating crushing blocks 20 will also be inserted into the soil, and then in the process of opening the opening cover 16, the crushing blocks 20 will also cut the soil, further improving the effect of removing the soil. ;
