Description

Technical Field

[0001] This application relates to the technical field of pile foundations, and in particular to a mud conveying device for a rigid composite pile integrated machine. Background Technology

[0002] During the construction of rigid composite piles, a pilot hole is drilled into the soil using a long spiral drill rod, and cement slurry is sprayed using a nozzle installed at the head of the long spiral drill rod. During the drilling process, as the cement slurry is sprayed, cement slurry and other grout continuously leak out from the opening of the pile hole, causing mud flooding at the construction site and affecting the overall construction.

[0003] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0004] In order to prevent the sludge generated during drilling from being directly discharged to the construction site, this application provides a mud conveying device for a rigid composite pile integrated machine.

[0005] The mud conveying device for a rigid composite pile integrated machine provided in this application adopts the following technical solution: A mud conveying device for a rigid composite pile integrated machine includes a guide assembly coaxially disposed outside a long spiral drill rod and a conveying assembly for conveying mud. The guide assembly includes a guide pipe coaxially disposed outside the long spiral drill rod and a guide plate disposed above the guide pipe. A discharge hole is penetrating the guide plate and the discharge hole is connected to the guide pipe. The conveying assembly includes a conveying track, a spiral blade disposed within the conveying track, and a conveying drive component for driving the spiral blade to rotate. The conveying track is open at the top and is located below the end of the guide plate away from the axis of the guide tube. The end of the spiral blade away from its axis abuts against the inner wall of the conveying track.

[0006] By adopting the above technical solution, after the silt flows out of the pile hole, the silt moves along the guide pipe to the upper part of the guide plate, and then the silt enters the conveying track and is conveyed by the conveying track to a position away from the pile hole, so that the silt will not accumulate at the construction position.

[0007] Optionally, it also includes a collection tank for collecting sludge, wherein a drain port communicating with the inner cavity of the lower side wall of the end of the conveying track away from the long spiral rod is provided, and the drain port is set to open towards the upper end of the collection tank.

[0008] By adopting the above technical solution, after the sludge is moved by the conveyor track, the sludge can be collected in the collection tank and will not remain on the construction site.

[0009] Optionally, the guide plate is tilted downward at the end near the conveyor track.

[0010] By adopting the above technical solution, after the sludge moves to the guide plate, it can move along the inclined surface of the guide plate towards a lower position, thereby entering the conveying track along the guide plate and making it less likely for the sludge to accumulate on the guide plate.

[0011] Optionally: Both ends of the guide plate that are not tilted downwards are provided with baffles, the upper end of the baffles is set higher than the upper end of the guide plate, and both ends of the baffles are fixed to the conveying track.

[0012] By adopting the above technical solution, the baffles ensure that the silt on the guide plate can only move towards the conveying track, thus preventing the silt on the guide plate from flowing randomly to the construction position.

[0013] Optionally: The upper end of the guide tube is fixed with a mounting plate, the mounting plate is fitted to the upper surface of the guide plate, and the guide tube passes through the guide plate and slides in cooperation with the guide plate.

[0014] By adopting the above technical solution, when the integrated machine moves, the guide tube can be separated from the guide tube, so that the guide tube will not obstruct the movement of the integrated machine due to being inserted into the soil. When the integrated machine moves to the designated construction position, the guide tube can be inserted into the discharge hole and the position of the guide tube relative to the guide plate can be limited by the mounting plate, so that the guide tube can be used normally.

[0015] Optionally, the upper end of the mounting plate is also provided with a hanging ring, which is respectively located on both sides of the axis of the guide tube and at the middle bend of the mounting plate.

[0016] By adopting the above technical solution, when it is necessary to move the guide plate, force can be applied to the hanging ring, so that there is a position on the mounting plate where force can be applied directly, making the upward movement of the mounting plate and guide tube more convenient and labor-saving.

[0017] Optionally: A guide tube is fixed to the lower end of the guide plate, the axis of the guide tube coincides with the axis of the discharge hole, the guide tube passes through the guide tube, and the outer diameter of the guide tube is smaller than the inner diameter of the guide tube.

[0018] By adopting the above technical solution, when the guide tube is inserted into the discharge hole, the vertical movement of the guide tube can be guided by the guide tube, so that the guide tube can maintain a vertical movement state when inserted into the discharge hole, thereby allowing the guide tube to surround the drilling position, so that the sludge generated by the drilling can enter the guide tube for discharge.

[0019] Optionally, the mounting plate has a plurality of abutment blocks at its lower end, and the abutment blocks abut against the upper end of the guide plate.

[0020] By adopting the above technical solution, a certain gap is left between the mounting plate and the guide plate. When there is silt between the mounting plate and the guide plate, the silt will not completely fill the gap between them. This ensures that the mounting plate and the guide plate will not be affected by the tension exerted by the silt when they are separated, making the separation of the mounting plate and the guide plate easier.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. After the silt flows out of the pile hole, the silt moves along the guide pipe to the upper part of the guide plate, and then the silt enters the conveying track and is conveyed by the conveying track to a position away from the pile hole, so that the silt will not accumulate at the construction position. 2. When the integrated machine moves, the guide tube can be separated from the guide tube, so that the guide tube will not obstruct the movement of the integrated machine due to being inserted into the soil. When the integrated machine moves to the marked construction position, the guide tube can be inserted into the discharge hole and the position of the guide tube relative to the guide plate can be limited by the mounting plate, so that the guide tube can be used normally.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a mud conveying device for a rigid composite pile integrated machine, such as... Figure 1 and Figure 2 As shown, it includes a guide assembly 1 coaxially disposed outside the long spiral drill rod and a conveying assembly 2 for conveying mud. The guide assembly 1 guides the mud from the pile hole to the conveying assembly 2, and then the conveying assembly 2 conveys the mud to the collection position, so that the mud does not accumulate and flow around the pile hole.

[0026] The guiding assembly 1 includes a guide tube 11 coaxially mounted outside the long spiral drill rod and a guide plate 12 for guiding the flow of mud. The guide tube 11 is vertically positioned, with its lower end inserted into the soil where the pile hole is located. A gap is left between the inner wall of the guide tube 11 and the long spiral drill rod, so that the rotation of the long spiral drill rod is not affected by the guide tube 11. The guide plate 12 is mounted on the integrated machine, with its two ends inclined downwards. A discharge hole 121 passes through the middle of the upper end of the guide plate 12, and the guide tube 11 passes through the discharge hole 121 with a sliding fit between them. The conveying assembly 2 includes a conveying track 21, spiral blades 22 disposed within the conveying track 21, and a conveying drive component 23 for driving the spiral blades 22 to rotate. The conveying track 21 is open at the top and is respectively disposed on both sides of the downwardly inclined portion of the guide plate 12 and located below the downwardly inclined portion of the guide plate 12. The helical blade 22 is rotatably connected to the conveying track 21, and the helical blade 22 can abut against the inner wall of the conveying track 21. During the rotation of the helical blade 22, it can drive the sludge to move in one direction. In this embodiment, the conveying drive component 23 is a motor. The motor is installed on the outer wall of the conveying track 21, and the output shaft of the motor is connected to the helical blade 22 through a coupling, thereby driving the helical blade 22 to rotate through the motor.

[0027] A drain port 211 communicating with its inner cavity is provided on the lower end face of the conveying track 21 away from the motor. A collection tank 3 is provided below the drain port 211. The collection tank 3 is placed on the ground and the drain port 211 faces the collection tank 3. The sludge conveyed by the two conveying tracks 21 can enter the collection tank 3 through the drain port 211 for collection, so that the sludge will not spread along the construction length.

[0028] When the sludge is squeezed onto the guide plate 12, if there is too much sludge on the guide plate 12, the sludge will also move along the non-downward-sloping end of the guide plate 12 and fall onto the construction position. Therefore, baffles 13 are provided at both ends of the non-downward-sloping guide plate 12. The upper surface of the baffle 13 is higher than the upper surface of the guide plate 12, and both ends of the baffle 13 are welded and fixed to the conveying track 21. Thus, the baffles 13 guide the movement of the sludge, allowing it to move only towards the conveying track 21.

[0029] Since the entire structure needs to be moved to another reference point after the construction of one pile foundation is completed, and the guide pipe 11 would hinder the overall movement due to its contact with the soil, the guide pipe 11 is detachably connected to the guide pipe 12. An installation plate 14 is welded and fixed to the upper end of the guide pipe 11. The guide pipe 11 passes through the installation plate 14 and penetrates the upper surface of the installation plate 14, allowing the silt flowing out of the guide pipe 11 to move above the installation plate 14. The installation plate 14 abuts against the upper surface of the guide plate 12, and the lower surface of the installation plate 14 fits against the upper surface of the guide plate 12, allowing the silt to move along the installation plate 14 and the guide plate 12 towards the conveying track 21.

[0030] To make the movement of the mounting plate 14 more convenient, two hanging rings 15 are provided at the upper end of the mounting plate 14. The two hanging rings 15 are respectively located on both sides of the axis of the guide tube 11 and at the bending position in the middle of the mounting plate 14. When it is necessary to move the mounting plate 14, the mounting plate 14 can be moved by applying force to the rings.

[0031] Because the guide plate 12 is relatively thin, when the guide tube 11 is inserted into the discharge hole 121, the discharge hole 121 cannot completely restrict the vertical insertion of the guide tube 11, making it difficult to align the guide tube 11 with the marked pile hole position. Therefore, a guide tube 17 is welded to the lower end of the guide plate 12. The inner wall of the guide tube 17 coincides with the inner wall of the discharge hole 121, and the lower end of the guide tube 17 is higher than the lower end face of the guide tube 11 inserted into the discharge hole 121. The guide tube 11 can be inserted into the guide tube 17, and the inner diameter of the guide tube 17 is larger than the outer diameter of the guide tube 11, so that the movement of the guide tube 11 within the guide tube 17 is not easily obstructed, and the guide tube 17 can also guide the movement of the guide tube 11 to a certain extent.

[0032] Since tension is created between the mounting plate 14 and the guide plate 12 after the mounting plate 14 is attached to the guide plate 12, and this tension affects the separation of the mounting plate 14 and the guide plate 12, a number of abutment blocks 16 are fixed to the lower end of the mounting plate 14. The lower end of the abutment block 16 can abut against the upper surface of the guide plate 12. The abutment blocks 16 create a certain gap between the mounting plate 14 and the abutment blocks 16, so that when the silt enters between the mounting plate 14 and the guide plate 12, the silt cannot completely fill the gap between the mounting plate 14 and the guide plate 12. Therefore, the separation between the mounting plate 14 and the guide plate 12 is easier when the guide tube 11 is removed later.

[0033] The implementation principle of this embodiment is as follows: After the integrated machine moves to the drilling position, the guide tube 11 is inserted into the discharge hole 121 and the abutment block 16 on the mounting plate 14 abuts against the guide plate 12. Then, drilling is performed. During the drilling process, the sludge flows upward from the guide tube 11 and moves along the inclined surface of the mounting plate 14 and the guide plate 12 toward the conveying track 21. After entering the conveying track 21, the sludge moves toward the collection tank 3 under the drive of the spiral blade 22 and finally flows into the collection tank 3.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
