Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to a slag cleaning device for bored cast-in-place piles in a foundation pit. Background Art

[0002] Bored piles are formed by drilling pile holes in non-hard soil using a drilling machine. After reaching the designed elevation, a steel skeleton is hoisted into the hole and concrete is poured into the pile body to form a bored pile foundation. It is the most commonly used pile foundation form in deep foundations. During the drilling operation, in order to ensure that the drill bit can operate normally and the overall stability of the drilled pile hole, the drill debris generated during the drilling operation needs to be cleaned out from the inside of the pile hole through slag cleaning equipment.

[0003] When cleaning the drill cuttings inside the pile hole, the impact drill needs to stop drilling and then clean the drill cuttings inside the pile hole. This operation takes a long time for the entire drilling operation, thereby affecting the working efficiency of the entire drilling. In the prior art, although the reverse circulation rotary drill can perform the slag cleaning operation while drilling, the reverse circulation rotary drill is relatively large and inconvenient to transport to the construction site. In addition, the reverse circulation drilling machinery and equipment are relatively expensive and inconvenient for multi-point construction.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 7As shown, the utility model is a slag cleaning device for bored piles in foundation pits, comprising a drill rod body 1, an outer surface of the drill rod body 1 is provided with a mounting groove 2, a connecting assembly 3 is provided inside the mounting groove 2, an outer shell of the connecting assembly 3 is provided with a jetting assembly 4, a recovery pipe 5 is provided on one side of the drill rod body 1, a mud pool 6 is provided at one end of the jetting assembly 4 and the recovery pipe 5, a filtering assembly 7 is provided inside the mud pool 6, a guide assembly 8 is provided on the other side of the drill rod body 1, and the guide end of the guide assembly 8 is threadedly connected to the connecting assembly 3.

[0031] By installing the connecting assembly 3 on the outer surface of the drill rod body 1, the drill rod body 1 can drive one end of the injection assembly 4 to move downward when the drill rod body 1 drives the drill bit downward for drilling operations. The guide assembly 8 can limit the connecting assembly 3 when the connecting assembly 3 moves downward, so that the connecting assembly 3 will not rotate with the drill rod body 1 while following the drill rod body 1 to move downward. At this time, the mud inside the mud pool 6 can be sprayed to the bottom of the pile hole through the injection assembly 4, and the drill cuttings inside the pile hole can rise to the hole mouth under a large amount of mud pressure. The recovery pipe 5 can extract the mud and drill cuttings rising to the hole mouth and extract them into the mud pool 6. When the extracted mud and drill cuttings fall into the mud pool 6, the filter assembly 7 can filter the drill cuttings and some other impurities carried in the mud.

[0032] The injection assembly 4 can be moved along with the drill pipe body 1 by connecting the assembly 3 and the guide assembly 8, so that the bottom end of the injection assembly 4 can always be at the bottom of the pile hole. At the same time, the mud in the mud pool 6 can be sprayed to the bottom of the pile hole through the injection assembly 4. Under the action of the mud flow and pressure, the drill cuttings at the bottom of the pile hole can rise to the hole mouth, so that the recovery pipe 5 can extract the drill cuttings and mud at the hole mouth. When the filter assembly 7 filters out the drill cuttings carried in the extracted mud, the mud can directly fall into the mud pool 6. As the injection assembly 4 continuously sprays the mud to the bottom of the pile hole and the recovery pipe 5 continuously transports the mud to the inside of the mud pool 6, the whole process can form a reverse circulation process, and at the same time overcomes the disadvantage of the impact drill generally stopping to remove the cuttings and slag, which consumes too much time, and can achieve continuous drilling and improve work efficiency. In addition, with the cooperation of the above-mentioned components and the impact drill, the effect of reverse circulation hole-forming mechanical slag removal can be achieved, so that the cost will not increase too much when carrying out multi-point construction.

[0033] In one embodiment, the connecting component 3 includes a first connecting ring 301, a second connecting ring 302 is fixedly installed on one side of the first connecting ring 301, and balls 303 are provided on the inner walls of the first connecting ring 301 and the second connecting ring 302, and the balls 303 are in contact with the inner wall of the mounting groove 2.

[0034] By putting the first connecting ring 301 and the second connecting ring 302 inside the installation groove 2, and then fixing the first connecting ring 301 and the second connecting ring 302 together by bolts and nuts, this arrangement makes it more convenient to install the connecting assembly 3 on the drill rod body 1. At the same time, when the drill rod body 1 rotates, the first connecting ring 301 and the second connecting ring 302 will not rotate under the guidance of the guide assembly 8, but the ball 303 can rotate on the inner wall of the installation groove 2. The arrangement of the ball 303 can reduce the friction between the drill rod body 1 and the first connecting ring 301 and the second connecting ring 302 when it rotates, thereby improving the service life of the connecting assembly 3.

[0035] In one embodiment, for the above-mentioned injection assembly 4, the injection assembly 4 includes a connecting rod 401, the connecting rod 401 is fixedly connected to the first connecting ring 301, one end of the connecting rod 401 is fixedly connected to a diverter pipe 402, the bottom end of the diverter pipe 402 is fixedly connected to an injection pipe 403, the top of the diverter pipe 402 is fixedly connected to a connecting pipe 404, and the top of the connecting pipe 404 is fixedly installed with a transport pipe 405.

[0036] The transport pipe 405 and the connecting pipe 404 can be connected together through a connecting flange, so that the transport pipe 405 can transport the mud inside the mud pool 6 to the inside of the diversion pipe 402 through the connecting pipe 404, and the mud inside the diversion pipe 402 is sprayed to the bottom of the pile hole through multiple injection pipes 403. The arrangement of the diversion pipe 402 and the injection pipe 403 makes it relatively uniform when the mud is sprayed to the bottom of the pile hole, so that the drill cuttings at the bottom of the pile hole can be better raised to the hole mouth. At the same time, the diversion pipe 402 and the injection pipe 403 can be made of steel, so that the diversion pipe 402 and the injection pipe 403 are not easily deformed as a whole during use.

[0037] In one embodiment, for the above-mentioned mud pool 6, the top of the mud pool 6 is fixedly connected to a guide frame 9, the recovery pipe 5 is fixedly installed together with the guide frame 9, the top of the mud pool 6 is fixedly connected to a mounting seat 10, the transport pipe 405 is fixedly installed together with the mounting seat 10, and the outer surfaces of the recovery pipe 5 and the transport pipe 405 are both provided with a mud pump 11.

[0038] With the assistance of the corresponding mud pump 11, the transport pipe 405 can extract the mud inside the mud pool 6, and the recovery pipe 5 can extract the mud and drill cuttings at the orifice with the assistance of the corresponding mud pump 11. At the same time, the guide frame 9 can make one end of the recovery pipe 5 directly located in the center of the mud pool 6. This setting enables the filter assembly 7 to better filter the drill cuttings inside the mud, and the extraction end of the transport pipe 405 can better extend into the mud pool 6 and extract the filtered mud under the fixation of the mounting seat 10.

[0039] In one embodiment, for the above-mentioned filter assembly 7, the filter assembly 7 includes a collecting bucket 701, and the collecting bucket 701 is movably connected to the mud pool 6. A support groove 702 is provided at the bottom of the collecting bucket 701, and a filter plate 703 is movably connected inside the support groove 702. A receiving groove 704 is provided on one side of the filter plate 703, and a handle 705 is provided inside the receiving groove 704. The handle 705 is fixedly connected to the filter plate 703, and both sides of the collecting bucket 701 are fixedly connected with support legs 706, and the bottom end of the support leg 706 is fixedly installed with a universal wheel 707.

[0040] The mud extracted by the recovery pipe 5 can directly fall into the interior of the collecting bucket 701. At this time, the filter plate 703 at the bottom of the collecting bucket 701 can filter the drilling cuttings inside the mud, so that the mud falling into the mud pool 6 can be kept clean as a whole. When cleaning the drilling cuttings collected in the collecting bucket 701, the collecting bucket 701 can be moved out of the mud pool 6 with the assistance of the universal wheel 707 and the support leg 706. At this time, the inner wall of the mud pool 6 no longer limits the filter plate 703, and then it is moved to a suitable position. Next, the handle 7 is used to 05 pulls the filter plate 703 so that the filter plate 703 can move out of the interior of the collecting bucket 701 through the supporting groove 702. When the filter plate 703 moves, the collecting bucket 701 blocks the drill cuttings on the filter plate 703. As the filter plate 703 continues to move, the drill cuttings on the filter plate 703 can fall directly from the interior of the collecting bucket 701. In summary, the arrangement of the universal wheel 707, the supporting legs 706, the supporting groove 702, the filter plate 703 and the handle 705 makes it more convenient to clean the drill cuttings collected in the collecting bucket 701.

[0041] In one embodiment, for the above-mentioned filter assembly 7, the filter assembly 7 also includes a positioning frame 708, the support leg 706 is movably connected to the positioning frame 708, a slot 709 is opened on one side of the positioning frame 708, the slot 709 passes through the support leg 706, and a column 710 is inserted into the inside of the slot 709, and a connecting rope 711 is provided between the column 710 and the positioning frame 708.

[0042] After the collecting bucket 701 is moved to the inside of the mud pool 6, the supporting leg 706 can be moved to the inside of the positioning frame 708. At this time, the column 710 is directly inserted into the inside of the slot 709, so that the column 710 can limit and fix the supporting leg 706 through the slot 709. This setting ensures the stability of the collecting bucket 701 when collecting drill cuttings, and the setting of the connecting rope 711 makes it less likely for the column 710 to be lost.

[0043] In one embodiment, for the above-mentioned guide assembly 8, the guide assembly 8 includes a positioning plate 801, the bottom of the positioning plate 801 is fixedly connected to a positioning cone 802, the top of the positioning plate 801 is movably connected to a guide rod 803, the bottom end of the guide rod 803 is fixedly connected to a threaded rod 804, the threaded rod 804 is threadedly connected to the second connecting ring 302, and the top of the guide rod 803 is provided with a threaded hole 805.

[0044] The positioning plate 801 can be placed on one side of the pile hole and the positioning cone 802 can be inserted into the soil. At the same time, a heavy object can be placed on the top of the positioning plate 801 to fix it. Then the guide rod 803 is passed through the hole groove opened on the positioning plate 801 and connected to the second connecting ring 302. When the drill pipe body 1 drives the connecting assembly 3 to move, the second connecting ring 302 can drive the guide rod 803 to move downward. At the same time, the guide rod 803 can slide inside the hole groove opened in the positioning plate 801. Under the restriction of the guide rod 803 and the positioning plate 801, the first connecting ring 301 and The second connecting ring 302 will not rotate with the drill pipe body 1. At the same time, as the guide rod 803 continues to move downward, the operator can rotate the threaded rod 804 at the bottom end of the second guide rod 803 into the inside of the threaded hole 805 set at the top end of the first guide rod, so that the two guide rods 803 can be assembled together. This setting allows the guide rod 803 to be continuously assembled and lengthened when guiding the connecting assembly 3, so that the overall guiding effect of the guide assembly 8 will not be affected, and the guide rod 803 does not need to be set too long.

[0045] Through the above technical solution, 1. the injection assembly 4 can move with the drill pipe body 1 through the connecting assembly 3 and the guide assembly 8, so that the bottom end of the injection assembly 4 can always be at the bottom of the pile hole, and at the same time, the mud inside the mud pool 6 can be sprayed to the bottom of the pile hole through the injection assembly 4. Under the action of the mud flow and pressure, the drill cuttings at the bottom of the pile hole can rise to the hole mouth, so that the recovery pipe 5 can extract the drill cuttings and mud at the hole mouth. When the filter assembly 7 filters out the drill cuttings carried in the extracted mud, the mud can directly fall into the mud pool 6. As the injection assembly 4 continuously sprays mud to the bottom of the pile hole, and the recovery pipe 5 continuously transports mud to the inside of the mud pool 6, the whole process can form a reverse circulation process, and at the same time overcomes the shortcomings of the impact drill generally stopping to drill and remove cuttings, which consumes too much time, and can achieve continuous drilling, improve work efficiency, and with the cooperation of the above components and the impact drill, reverse circulation hole-forming mechanical slag cleaning can be achieved. 703 is moved out of the collecting hopper 701 through the support groove 702.
