Description

Technical Field

[0001] This application relates to the field of soil removal technology, and in particular to a spiral soil removal and cleaning mechanism for bridge pile foundations. Background Technology

[0002] Bridge pile foundations are the lowest part of a bridge structure that directly contacts the ground, and are an important component of the bridge's substructure. To ensure the normal use and safety of the bridge, bridge pile foundations must possess sufficient strength and stability.

[0003] In existing technologies, before the bridge pile foundation is poured, a pouring hole needs to be drilled at a predetermined location. Soil and rock waste will be generated during the drilling process. This waste usually accumulates around the hole, taking up space and affecting the construction progress. Currently, the traditional method for cleaning this waste is to use manual cleaning, which requires stopping the drilling and has low cleaning efficiency, seriously affecting the construction efficiency.

[0004] Therefore, it is necessary to propose a spiral soil removal and cleaning mechanism for bridge pile foundations to improve construction efficiency, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a spiral soil removal and cleaning mechanism for bridge pile foundations, which aims to solve the problem that the traditional method of cleaning soil and rock waste in the prior art is to use manual cleaning, which requires stopping drilling during cleaning and has low cleaning efficiency, seriously affecting construction efficiency.

[0006] To achieve the above objectives, this application proposes a spiral soil removal and cleaning mechanism for bridge pile foundations, comprising: a soil removal cylinder with a conveying space inside; a soil removal shaft rotatably disposed inside the soil removal cylinder; spiral blades disposed on the outer circumference of the soil removal shaft; a soil removal drive for rotating the soil removal shaft; a soil inlet disposed at the bottom of the soil removal cylinder; a soil discharge outlet disposed at the top of the soil removal cylinder; and a soil inlet frame disposed in the soil removal cylinder and connected to the soil inlet.

[0007] In some embodiments, the system further includes: a suction port disposed on the soil discharge cylinder and opposite to the soil inlet; a suction pipe disposed on the soil discharge cylinder and connected to the suction port; and a suction drive disposed on the suction pipe.

[0008] In some embodiments, it further includes: a tapered frame, the tapered frame being connected to the soil entry frame.

[0009] In some embodiments, the system further includes: a top mounting plate, connecting ends at both ends of the soil discharge cylinder, the connecting end at the top of the soil discharge cylinder being connected to the top mounting plate, and a soil discharge drive being mounted on the top mounting plate.

[0010] In some embodiments, it further includes: a bottom mounting plate, a connecting end at the bottom of the soil discharge cylinder connected to the bottom mounting plate, and a suction drive mounted on the bottom mounting plate.

[0011] In some embodiments, it further includes a drain hole disposed on the bottom mounting plate and communicating with the conveying space.

[0012] This application proposes a spiral soil removal and cleaning mechanism for bridge pile foundations, comprising: a soil removal cylinder with a conveying space inside; a soil removal shaft rotatably disposed inside the soil removal cylinder; spiral blades disposed on the outer circumference of the soil removal shaft; a soil removal drive for rotating the soil removal shaft; a soil inlet located at the bottom of the soil removal cylinder; a soil discharge outlet located at the top of the soil removal cylinder; and a soil inlet frame located within the soil removal cylinder and connected to the soil inlet. When drilling the holes for the bridge pile foundations, the soil inlet frame of the spiral soil removal and cleaning mechanism is positioned next to the holes. Drilled soil, rocks, and other waste materials enter the soil inlet frame and, upon entering the bottom of the conveying space through the soil inlet, the soil removal drive is activated. The drive outputs rotational power, thereby driving the soil removal shaft to rotate. The soil, rocks, and other waste materials are then transported to the top of the conveying space via the spiral blades and the soil removal cylinder and discharged from the soil discharge outlet. The above steps can efficiently clean up the drilled soil, rocks and other waste materials, and can be done simultaneously with drilling the bridge pile foundation holes without stopping the drilling process, thus effectively improving construction efficiency.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this application proposes a spiral soil removal and cleaning mechanism for bridge pile foundations, comprising: a soil removal cylinder 1, which has a conveying space inside; a soil removal shaft 12, which is rotatably disposed inside the soil removal cylinder 1; spiral blades 13, which are disposed on the outer circumferential surface of the soil removal shaft 12; a soil removal drive 3, which is used to drive the soil removal shaft 12; a soil inlet, which is disposed at the bottom of the soil removal cylinder 1; a soil removal port 16, which is disposed at the top of the soil removal cylinder 1; and a soil inlet frame 11, which is disposed in the soil removal cylinder 1 and connected to the soil inlet.

[0024] The soil discharge cylinder 1 is the structural foundation of the spiral soil discharge and cleaning mechanism for bridge pile foundations. All other structures on the spiral soil discharge and cleaning mechanism for bridge pile foundations are directly or indirectly connected to the soil discharge cylinder 1. The soil discharge cylinder 1, soil discharge shaft 12, spiral blades 13, and soil discharge drive 3 are the core components of the spiral soil discharge and cleaning mechanism for bridge pile foundations. The soil discharge drive 3 is a rotary power source that drives the soil discharge shaft 12 to rotate, thereby driving the spiral blades 13 to rotate, transporting soil, rocks, and other waste materials from the bottom to the top of the soil discharge cylinder 1 and discharging them from the soil discharge port 16. The soil inlet frame 11 is arranged near the hole position of the bridge pile foundation. The soil, rocks, and other waste materials drilled out enter the soil inlet from the soil inlet frame 11, thereby entering the bottom of the soil discharge cylinder 1, and are transported to the top of the soil discharge cylinder 1 by the spiral blades 13 and discharged.

[0025] Specifically, when drilling the holes for bridge pile foundations, the soil inlet frame 11 of the bridge pile foundation spiral soil removal and cleaning mechanism is placed next to the hole. Drilled soil, rocks, and other waste materials enter the soil inlet frame 11 and, upon entering the bottom of the conveying space through the inlet, the soil removal drive 3 is activated. The soil removal drive 3 outputs rotational power, thereby driving the soil removal shaft 12 to rotate. The spiral blades 13 and the soil removal cylinder 1 transport the soil, rocks, and other waste materials to the top of the conveying space and discharge them through the soil removal port 16. Through these steps, the drilled soil, rocks, and other waste materials can be efficiently cleaned, and this cleaning can be performed simultaneously with drilling the bridge pile foundation holes without stopping the drilling process, effectively improving construction efficiency.

[0026] In detail, when drilling holes for bridge pile foundations, due to the presence of a large amount of water in the surrounding area, a retaining structure needs to be set up around the hole location to isolate the water and prevent it from affecting the drilling process. Due to cost constraints, the area of ​​the retaining structure cannot be too large, making it impossible to use large excavation equipment to remove the drilled soil, rocks, and other waste. However, the vertical soil-discharging cylinder 1 allows for efficient soil discharge within the effective retaining space without interfering with the equipment used for drilling the bridge pile foundation holes. This allows for simultaneous drilling and soil discharge, effectively improving construction efficiency. The preferred method for driving the soil discharge is using an electric motor.

[0027] Among them, the soil discharge cylinder 1, soil discharge shaft 12 and spiral blade 13 are all made of stainless steel. Stainless steel has good mechanical properties and excellent corrosion resistance, which helps the spiral soil discharge cleaning mechanism for bridge pile foundations adapt to diverse and harsh construction environments.

[0028] See Figure 1 As shown, in some embodiments, the system further includes: a suction port 17, which is disposed in the soil discharge cylinder 1 and opposite to the soil inlet; the suction port 17 communicates with the internal conveying space and is coaxial with the soil inlet; a suction pipe 5, which is disposed in the soil discharge cylinder 1 and communicates with the suction port 17; the suction pipe 5 is welded to the soil discharge cylinder 1 and communicates with the suction port 17, thereby communicating with the conveying space; and a suction drive 6, in which the suction pipe 5 is disposed. The suction drive 6 is provided with an air intake, one end of the suction pipe 5 is connected to the air intake, and the other end of the suction pipe 5 is connected to the suction port 17. The suction drive 6 generates suction to draw soil, rocks, and other waste materials near the soil inlet into the bottom of the conveying space, which helps to enhance the soil suction efficiency.

[0029] See Figure 1 As shown, in some embodiments, it further includes: a gradually expanding frame 10, which is connected to the soil inlet frame 11. The gradually expanding frame 10 is used to increase the opening of the soil inlet frame 11, so that soil, rocks and other waste materials in a larger range can pass smoothly through the soil inlet frame 11 and enter the bottom of the conveying space.

[0030] See Figure 2 and Figure 3 As shown, in some embodiments, it also includes: a top mounting plate 2, which is the base of the soil discharge drive 3 and other structures; connecting ends 9 are provided at both ends of the soil discharge cylinder 1; the connecting ends 9 at the top of the soil discharge cylinder 1 are connected to the top mounting plate 2; and the soil discharge drive 3 is installed on the top mounting plate 2.

[0031] In this embodiment, a transmission box is also provided on the top mounting plate 2. The soil discharge drive 3 is connected to the transmission box. The soil discharge shaft 12 is located inside the transmission box. A transmission mechanism is provided inside the transmission box. There are no specific restrictions on the transmission mechanism. It can be a worm gear mechanism. The worm is connected to the output end of the soil discharge drive 3, and the worm wheel is connected to the soil discharge shaft 12.

[0032] See Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, it also includes: a bottom mounting plate 8, which is the base of the suction drive 6 and other structures; the connecting end 9 at the bottom of the soil discharge cylinder 1 is connected to the bottom mounting plate 8; and the suction drive 6 is mounted on the bottom mounting plate 8.

[0033] In this embodiment, the suction drive 6 is provided with a mounting base 7. The mounting base 7 is screwed to the bottom mounting plate 8. One connecting end 9 of the soil discharge cylinder 1 is screwed to the top mounting plate 2, and the other connecting end 9 of the soil discharge cylinder 1 is screwed to the bottom mounting plate 8. One end of the soil discharge shaft 12 is rotatably connected to the bottom mounting plate 8 through a bearing 14, and the other end of the soil discharge shaft 12 is rotatably connected to the top mounting plate 2 through a bearing 14.

[0034] See Figure 2 and Figure 4 As shown, in some embodiments, a drainage hole 19 is also included. The drainage hole 19 is disposed on the bottom mounting plate 8 and communicates with the conveying space. Since the drilled soil contains a lot of water, if the water is not cleaned up in time, it will affect the soil conveying. The drainage hole 19 is used to drain the water from the soil, which helps to improve the cleaning efficiency.

[0035] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
