[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Reference Figures 1-9 A dewatering device suitable for foundation pits in complex environments includes a partition basket 1 placed inside the foundation pit and a dewatering device placed inside the partition basket 1. The partition basket 1 forms a permeable and filterable bottom structure, making the dewatering device inside it less likely to be blocked or damaged by stones, debris, etc. during operation. The two work together to complete the dewatering operation of foundation pits in complex environments.

[0036] Among them, the partition basket 1 is a five-sided mesh structure with an open top, forming a reliable and effective isolation space.

[0037] It should be noted that the bottom of the partition basket 1 is flat, and its volume is matched to the actual bottom space of the foundation pit.

[0038] When in use, the material basket 1 can be placed at the bottom of the pit in advance, or it can be lowered and placed at the bottom of the pit together with the dewatering device.

[0039] After placing the partition basket 1, even if the bottom of the pit is uneven or the bottom environment is extremely poor, the partition basket 1 can form a reliable placement position for the dewatering device.

[0040] Furthermore, the rain gauge is lowered or raised via the lifting assembly 2; no manual movement is required, saving manpower, improving efficiency, and providing more reliable operability and safety.

[0041] When dewatering operations are required, lower this device to the bottom of the pit (the dewatering device is located inside the partition basket 1); then connect the dewatering device to the dewatering pipe, and the dewatering operation can be carried out.

[0042] In some embodiments, the separator basket 1 consists of a metal frame and a filter structure covering the metal frame.

[0043] Preferably, the metal frame is made of welded angle steel, with appropriate spacing between the angle steel to ensure the overall structural strength; meanwhile, the filter structure is a filter screen with an appropriate pore size, preferably made of rust-proof steel wire mesh.

[0044] Optionally, the filter structure may also include: a permeable cloth located between the metal mesh and the metal frame; which can better isolate fine debris such as silt.

[0045] In some embodiments, the dewatering device consists of an engine 3 and a submersible slurry pump 4 connected by a flange; it has a good and reliable dewatering rate and stable operation over a long period of time.

[0046] Understandably, an engine with appropriate power should be selected according to the requirements; among them, an electric motor or a fuel engine can be used to work in conjunction with the submersible slurry pump 4.

[0047] It should be noted that the lower end of the submersible slurry pump 4 is equipped with a liquid inlet screen; a bottom support structure should be installed to raise the bottom of the liquid inlet screen so that it does not contact the placement surface, thus ensuring an effective liquid inlet surface.

[0048] like Figure 6 As shown; the bottom support structure of the submersible slurry pump 4 is an inverted bowl-shaped body with multiple through-holes connecting the inside and outside of the bowl-shaped body; the bowl-shaped body provides reliable bottom support without affecting the liquid inlet; correspondingly, the liquid inlet net at the bottom of the submersible slurry pump 4 is located in the internal space of the bowl-shaped body.

[0049] It should be noted that the lower end of the bowl-shaped body is supported by a complete ring, which ensures stability.

[0050] In some embodiments, the lifting component 2 is a hand-operated hoist; it is simple to install and use, and reliably lifts and lowers the rain gauge; of course, other types of components can also be used to achieve the lifting and lowering adjustment of the rain gauge.

[0051] In some embodiments, the lifting assembly 2 is mounted via a support frame 5.

[0052] The support frame 5 is installed at a suitable position above the foundation pit, or it can be placed inside the foundation pit. The support frame 5 works in conjunction with the traction structure of the lifting component 2 to lift and lower the dewatering device.

[0053] Preferably, the support frame 5 consists of multiple diagonal braces 51 and a top plate 52 connecting all the diagonal braces 51; wherein the multiple diagonal braces 51 are arranged outwardly and evenly around the top plate 52 below.

[0054] It should be noted that there should be no fewer than three diagonal braces (51) to ensure the stability of the system.

[0055] like Figure 1As shown, three diagonal braces 51 are fixedly connected below the top plate 52 to form a triangular support structure.

[0056] The top plate 52 is made of steel plate, preferably round steel plate; the diagonal brace 51 is made of steel pipe or round steel and is welded to the steel plate.

[0057] Furthermore, tie rods are fixedly connected between adjacent diagonal braces 51 to improve the stability of the support system.

[0058] In addition, a lifting ring is pre-welded or assembled below the top plate 52 for connecting the top of the chain hoist.

[0059] In some embodiments, a level bubble 53 is provided on the outer ring side of the top plate 52 to help adjust the support system to a suitable state (in the horizontal state, the support frame 5 is more stable under force).

[0060] Preferably, there are at least three horizontal bubbles 53 arranged around the perimeter to facilitate observation from various angles; it should be noted that in normal operation, the horizontal bubbles 53 are placed horizontally.

[0061] Furthermore, the level bubble 53 has a first configuration of horizontal placement and a second configuration of vertical placement; thus, the level bubble 53 can be adjusted according to personal habits and environmental needs; in addition, it can be easily replaced when a level bubble 53 is damaged.

[0062] Specifically, the top plate 52 has an insertion hole on its outer ring side, and the rear end of the horizontal bubble 53 is fixedly provided with a post; the horizontal bubble 53 is assembled on the outer ring side of the top plate 52 by the cooperation of the post and the insertion hole.

[0063] Meanwhile, a positioning groove is provided on the outer side of the insertion hole, and a positioning strip is integrally provided on the outer side of the insertion post; at least two positioning grooves are provided; the assembly state can be adjusted to horizontal or vertical by the cooperation of the positioning strip and the positioning groove.

[0064] Preferred, such as Figures 7-9 As shown; the outer side of the socket is provided with four evenly surrounding positioning grooves, and the outer side of the plug is integrally provided with four evenly surrounding positioning strips.

[0065] In some embodiments, the lower end of the diagonal brace 51 is rotatably fitted with a support leg 6 to obtain a more stable support foundation.

[0066] Preferably, the support 6 includes: a sleeve 61 that is fitted onto the lower end of the diagonal brace 51 and rotates thereon, and a support plate 62 that is hinged to the lower end of the sleeve 61.

[0067] It should be noted that the support leg 6 and the diagonal brace 51 are detachable; the whole assembly rotates with the diagonal brace 51; and with the adjustment of the support plate 62, it can be adjusted to the most suitable placement according to the support point, so as to keep the support point effective and reliable.

[0068] Furthermore, a through hole 63 is provided on the support plate 62.

[0069] Preferably, there are at least two through holes 63; the support plate 62 is fixed to the base surface by connecting parts such as ground nails and expansion bolts through the through holes 63.

[0070] In some embodiments, the storage basket 1 is connected to the rain shower via a pull rope 71.

[0071] Preferably, a perforated ring is fixedly installed on the rain gauge; the perforated ring is connected to the upper end of the pull rope 71 through the strip opening.

[0072] Furthermore, the upper end of the pull rope 71 is equipped with a hook; the hook engages with the strip opening of the perforated ring for easy installation and removal.

[0073] This device has been applied to deep foundation pit dewatering projects in intercity railways and can also be used for dewatering operations in other foundation pit projects. The device consists of angle iron, a filter screen, steel pipes, a hand-operated hoist, an engine, and a slurry pump. The materials are readily available, easy to weld, highly safe, and easily operable.

[0074] In practical use, a suitable engine and submersible slurry pump are selected according to the dewatering requirements of the foundation pit. Steel pipes of different lengths are welded into a triangular support, with a circular steel plate welded to the top of the support and fixed to the steel pipe. A lifting ring is welded to the lower part of the circular steel plate at the top of the support, and a hand-operated hoist is suspended from it. An engine with appropriate power is selected according to the requirements. To accelerate the dewatering process, a submersible slurry pump is selected as the water pump and connected to the engine via a flange. The hand-operated hoist is connected to the engine via a wire rope and a fixing buckle, enabling it to move up and down. A "separation basket" is fabricated using angle steel, a filter screen, and permeable cloth and placed around the suction port of the submersible slurry pump to isolate stones and prevent pump blockage.

[0075] This device is made from common materials, is simple to manufacture, and is easy to operate and highly practical. Compared to conventional water pumping methods, it saves labor costs, reduces the chance of equipment damage, and speeds up the pumping process. The inclusion of a strainer basket isolates debris such as stones, preventing pump blockage. The slurry pump is moved up and down using a custom-made tripod and a hand-operated hoist. Compared to the conventional method of manually moving a water pump, this method is safer and more efficient, and the device can adapt to various complex environments and terrains, making it highly versatile.
