Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a portable, lightweight wellpoint dewatering device. Background Technology

[0002] Vacuum pump lightweight wellpoint dewatering is a construction technique used to lower the groundwater level. This technique involves inserting a series of closely spaced small-diameter wellpoint pipes deep into the underground aquifer, and then using a vacuum pump to extract the air from the wellpoint pipes to create a negative pressure environment. This causes groundwater to flow into the wellpoint pipes under the pressure difference, and then the water is discharged by the surface drainage system, thereby achieving the purpose of lowering the groundwater level.

[0003] Currently, the most common method for drilling is using drilling equipment. However, due to the large size and inconvenience of moving drilling equipment, it is difficult for workers to operate during construction, which seriously reduces construction efficiency and needs to be improved.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown, a portable lightweight wellpoint dewatering device includes a handheld wheel 1, a mounting base 2, a drive mechanism 3, a dewatering pipe 4, and a drill pipe 5.

[0028] like Figure 2 , Figure 3 As shown, the handheld wheel 1 is for workers to hold and support. The mounting base 2 is horizontally set in the middle of the handheld wheel 1. A connecting pipe 6 is vertically rotatably connected to the mounting base 2, and a water injection pipe 7 is rotatably connected to the upper end of the connecting pipe 6.

[0029] like Figure 2 , Figure 3 As shown, the drive mechanism 3 is used to control the rotation of the connecting pipe 6. The drive mechanism 3 includes a driven pulley 31, a driving pulley 32, a transmission belt 33, and a connector 34.

[0030] like Figure 2 , Figure 3 As shown, the driven pulley 31 is disposed on the outer wall of the connecting pipe 6, and the driving pulley 32 is rotatably connected to the mounting base 2. The diameter of the driven pulley 31 is larger than the diameter of the driving pulley 32. The transmission belt 33 is wound around the outer walls of the driven pulley 31 and the driving pulley 32. The connector 34 is disposed on the driving pulley 32 and is used to connect an electric drill.

[0031] like Figure 2 , Figure 3 As shown, the downwater pipe 4 is vertically installed at the lower end of the connecting pipe 6. The downwater pipe 4 has multiple sections, which are connected by threads. The upper end of each downwater pipe 4 is threaded to the connecting pipe 6.

[0032] like Figure 2 , Figure 3 As shown, the drill pipe 5 is vertically threaded to the lower end of the downpipe 4. Several permeable holes 51 are evenly distributed on the drill pipe 5, and a drill bit 52 is provided at the lower end.

[0033] When drilling for dewatering is required, first connect the drill pipe 5 to the lower end of the dewatering pipe 4, then connect the dewatering pipe 4 to the lower end of the connecting pipe 6. Then, one worker holds the handwheel 1 to make the drill pipe 5 perpendicular to the ground, and another worker holds the electric drill and inserts it into the connector 34. Then, connect the tap water pipe to the water injection pipe 7 so that cold water can enter the dewatering pipe 4 and the drill pipe 5.

[0034] Then, the electric drill is controlled to rotate, causing the electric drill to drive the drive pulley 32 to rotate. Under the action of the transmission belt 33, the driven pulley 31 rotates synchronously. Since the diameter of the driven pulley 31 is larger than the diameter of the drive pulley 32, the driven pulley 31 rotates slowly, causing the connecting pipe 6 to rotate synchronously.

[0035] Simultaneously, the connecting pipe 6 drives the downwater pipe 4 and the drill pipe 5 to rotate synchronously, causing the drill bit 52 on the drill pipe 5 to penetrate deeper, and working with the cold water flowing out of the permeable hole 51 to form a water drill, thus realizing automatic drilling operations. After the first downwater pipe 4 is drilled into the ground, the connecting pipe 6 is removed from the downwater pipe 4, and another downwater pipe 4 is tightened and fixed to the downwater pipe 4 below, and then fixed to the connecting pipe 6, thus realizing the drilling and installation of the next section of downwater pipe 4.

[0036] Once the water level is reached, the topmost downwater pipe 4 is removed from the connecting pipe 6, and the pumping pipe is then connected to the topmost downwater pipe 4. Through the cooperation of the permeable hole 51 and the downwater pipe 4, the groundwater is pumped out.

[0037] Therefore, by setting up a handheld wheel 1 for workers to hold, and rotating a connecting pipe 6 on the handheld wheel 1, the downpipe 4 connected to the drill pipe 5 can be directly fixed to the connecting pipe 6. The power provided by the electric drill can be used to control the rotation of the connecting pipe 6, so as to realize the automatic drilling of the drill pipe 5. At the same time, the drill pipe 5 carrying the downpipe 4 is directly located in the borehole, completing the synchronous construction of drilling and laying of the downpipe 4. The whole process is simple to operate and has high construction efficiency.

[0038] Meanwhile, by setting up a simple and portable rain-prevention device, it is easy to assemble and use in various complex construction sites, and it is also easy to reuse.

[0039] like Figure 2 , Figure 4 As shown, the connecting pipe 6 is flush with the outer wall of the downpipe 4. The connecting pipe 6 is equipped with a disassembly and assembly tool 8 for loosening the downpipe 4. The disassembly and assembly tool 8 includes a pair of retaining rings 81, a handle 82 and a retaining block 83.

[0040] like Figure 4As shown, the retaining ring 81 is semi-circular and is used to clamp the outer wall of the connecting pipe 6 and the downcomer pipe 4 after fastening. One retaining ring 81 has a locking hook 84 at both ends, and the other retaining ring 81 has a locking hole 85 at both ends for the locking hook 84 to pass through.

[0041] like Figure 4 As shown, the handle 82 is disposed on the outer wall of the retaining ring 81, the retaining block 83 is disposed on the inner wall of the retaining ring 81, and the outer wall of the downpipe 4 is provided with a groove 86 for the retaining block 83 to be inserted.

[0042] When it is necessary to install or remove the downpipe 4, take out the installer 8, make a pair of retaining rings 81 interlock and wrap around the downpipe 4 and connecting pipe 6, then align the retaining blocks 83 on the retaining rings 81 with the retaining grooves 86 on the outer wall of the downpipe 4, and press the pair of retaining rings 81 so that the locking hooks 84 on the retaining rings 81 pass through the locking holes 85 and hook together. Then, control the handle 82 to rotate the retaining rings 81, thereby realizing the rotation control of the downpipe 4, and using the lever principle to easily tighten or loosen the downpipe 4.

[0043] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
