Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a well dewatering filter pipe. Background Technology

[0002] When carrying out underground engineering construction, groundwater often hinders the construction process. Most projects use dewatering methods. Dewatering involves using dewatering equipment to extract groundwater and dry the construction area before construction can begin. However, during the extraction of groundwater, since the groundwater is contained in the soil, the extraction often also removes the mud and sand mixed in with the water. This can easily cause soil erosion, and the extracted mud and sand can also clog the pumping equipment.

[0003] An existing dewatering pipe filtration device consists of a dewatering pipe, a dewatering filter, a pipe joint, an outer sheath of the dewatering filter pipe, a permeable concrete pipe, and a sand filter layer. The dewatering pipe is located above the dewatering filter pipe and is connected to it via the pipe joint. The outer sheath of the dewatering filter pipe is attached to the outer surface of the dewatering filter pipe and placed inside the permeable concrete pipe. A sand filter layer is filled between the permeable concrete pipe and the clay layer. Although this dewatering pipe filtration device can prevent the extraction of silt mixed in the water, the filtration area is too small because the horizontal filter screen is only installed in the hollow cavity of the pipe joint. This makes it prone to clogging at the pipe joint, thus slowing down the pumping operation. Based on this, this utility model designs a well dewatering filter pipe to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a well dewatering filter pipe that can prevent the mud and sand mixed in the water from being pumped out during pumping operations, speed up the pumping operation, and replace the embedded mesh pipe in time when it is blocked.

[0005] This utility model is implemented as follows: A well dewatering filter pipe includes a support, a perforated steel pipe, an inner mesh pipe, an outer mesh pipe, and a gravel filter layer; the support is provided with multiple crossbars and a handle, the crossbars are multi-layered, each layer has multiple crossbars, and they are evenly distributed on the outer surface of the support; the handle is located at the top of the support; each crossbar has a pad at its outer end, the pad being an anti-slip rubber pad, and the pad is placed between the crossbar and the inner mesh pipe; the outer end of the pad has an open hook, and the support is detachably connected to the inner mesh pipe as an integral structure through the hook. The support and the inner mesh pipe do not contact each other, and the inner mesh pipe is supported on the outside of the support by the multiple crossbars; the support is placed inside the perforated steel pipe, the outer mesh pipe is attached to the outer surface of the perforated steel pipe, and the inner mesh pipe is located between the perforated steel pipe and the support; the gravel filter layer fills the space between the outer mesh pipe and the soil layer.

[0006] Furthermore, the embedded mesh tube is a steel wire mesh tube with a 0.1cm aperture, the outer mesh tube is a steel wire mesh tube with a 0.6cm aperture, and the gravel filter layer is gravel.

[0007] Furthermore, the outer mesh tube is attached to the outer surface of the perforated steel pipe by welding.

[0008] Furthermore, the vertical central axes of the perforated steel pipe, the support, the embedded mesh pipe, and the outer mesh pipe coincide.

[0009] Furthermore, the pad is bonded to the crossbar.

[0010] Furthermore, the hook is set horizontally.

[0011] Furthermore, the hook is located at the outer end of the bottommost pad.

[0012] The beneficial effects of this utility model are: by setting a perforated steel pipe and an outer mesh pipe, groundwater can quickly enter the interior of the perforated steel pipe, and the filtration area is increased by the embedded mesh pipe, thereby speeding up the pumping operation. Furthermore, the cooperation between the support and the embedded mesh pipe prevents the mud and sand mixed in the water from being pumped out during the pumping operation, and the embedded mesh pipe can be replaced in time when it becomes blocked.

[0019] Please see Figure 1 As shown, this utility model provides a well dewatering filter pipe. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0020] In a specific embodiment of the technical solution of this utility model:

[0021] The system includes a support frame 1, a perforated steel pipe 2, an embedded mesh pipe 3, an outer mesh pipe 4, and a gravel filter layer 5. The support frame has multiple crossbars 12 and handles 11. The crossbars 12 are multi-layered, with multiple crossbars 12 in each layer, evenly distributed on the outer surface of the support frame 1. The handles 11 are located at the top of the support frame 1. Each crossbar 12 has a pad 13 at its outer end. The pad 13 is a non-slip rubber pad, and it is placed between the crossbar 12 and the embedded mesh pipe 3. The outer end of the pad 13 has a... The bracket 1 is detachably connected to the embedded mesh tube 3 via an open hook 14, forming an integral structure. The bracket 1 and the embedded mesh tube 3 do not contact each other, and the embedded mesh tube 3 is supported externally by multiple crossbars 12. The bracket 1 is placed inside the perforated steel pipe 2, and the outer mesh tube 4 is attached to the outer surface of the perforated steel pipe 2. The embedded mesh tube 3 is located between the perforated steel pipe 2 and the bracket 1. A gravel filter layer 5 is filled between the outer mesh tube 4 and the soil layer 6. The bracket 1, crossbars 12, and pads 13 cooperate to support the embedded mesh tube 3, preventing it from being deformed by water flow and allowing for timely removal and replacement of the embedded mesh tube 3 if it becomes clogged. The perforated steel pipe 2 and the outer mesh tube 4 filter out larger particles of silt and allow groundwater to quickly enter the perforated steel pipe, thereby accelerating the pumping operation. The embedded mesh tube 3 prevents the silt and sand mixed in the water from being pumped out during pumping operations, thus acting as a filter. The gravel filter layer 5 filters out large particles of impurities in the groundwater, preventing them from clogging the perforated steel pipe 2 and the outer mesh tube 4. The pad block 13 increases the contact area between the support 1 and the embedded mesh tube 3, allowing the support 1 to better support the embedded mesh tube 3. The hook 14 makes the support 1 and the embedded mesh tube 3 a detachable, interconnected structure, and the handle 11 allows the entire structure to be pulled out from the perforated steel pipe 3.

[0022] The embedded mesh tube 3 is a 0.1cm mesh steel wire mesh, and the outer mesh tube 4 is a 0.6cm mesh steel wire mesh. The outer mesh tube 4 is attached to the outer surface of the perforated steel pipe 2 by welding. The gravel filter layer 5 is gravel. Using a coarser mesh steel wire mesh attached to the outer surface of the perforated steel pipe 2 by welding can prevent the mud and sand mixed in the water from being pumped out during pumping operations, while also preventing the outer mesh tube 4 from becoming clogged and reducing the water flow, thereby accelerating the drainage operation.

[0023] The vertical central axes of the perforated steel pipe 2, the support 1, the inner mesh pipe 3, and the outer mesh pipe 4 coincide.

[0024] The pad 13 is bonded to the crossbar 12. The pad 13 and the crossbar 12 are detachably connected by bonding, allowing the pad 13 to be replaced promptly when it wears out.

[0025] The hook 14 is horizontally positioned, making the bracket 1 and the embedded mesh tube 3 a seamlessly connected structure that allows for smoother disassembly and separation.

[0026] The hook 14 is located at the outer end of the bottom pad 13. Setting the hook 14 only at the outer end of the bottom pad 13 can save production costs and can also prevent the embedded mesh tube 3 from breaking when it is pulled out of the perforated steel pipe 2 through the bracket 1. Even if the embedded mesh tube 3 breaks accidentally during the pulling process, it can still be pulled out of the perforated steel pipe 2 intact.

[0027] The bracket 1, perforated steel pipe 2, embedded mesh pipe 3, and outer mesh pipe 4 are all installed vertically to the ground.

[0028] The gravel filter layer 5 is a 5cm thick layer of gravel filled between the outer mesh pipe and the soil layer after the support 1, the perforated steel pipe 2, the inner mesh pipe 3 and the outer mesh pipe 4 are installed.

[0029] In normal use, the bracket 1 only supports the embedded mesh tube 3 and can be pulled out from the perforated steel pipe 2. When the embedded mesh tube 3 is blocked by too much mud and sand, the bracket 1 can be rotated by the handle 11 while pulling the bracket 1 upward, so that the hook 14 hooks the embedded mesh tube 3, thereby connecting the bracket 1 and the embedded mesh tube 3 into an integral structure. Then the bracket 1 can be pulled out vertically, thereby taking out the embedded mesh tube 3 and replacing it with a new embedded mesh tube 3 to solve the blockage problem.

[0030] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
