Description

Technical Field

[0001] This utility model relates to the field of water drainage technology, specifically a construction water drainage and discharge device for deep foundation pits. Background Technology

[0002] Deep foundation pits refer to earthwork excavation, support, and dewatering projects involving pits (trenches) with an excavation depth exceeding 5 meters (including 5 meters), or those less than 5 meters but with complex geological conditions, surrounding environment, and underground pipelines, or those affecting the safety of adjacent buildings (structures). In recent years, with my country's rapid economic development and urban construction, a large number of high-rise buildings, super high-rise buildings, and municipal engineering projects have been built, leading to an increasing number of deep foundation pit projects. After determining the excavation plan, how to effectively carry out waterproofing and drainage work has become a key and challenging aspect of foundation construction. After the foundation pit is excavated, the water inside needs to be drained, which requires the use of water pumps.

[0003] Existing deep foundation pit construction water drainage devices have significant defects in use. On the one hand, the structural design of the part of the suction pipe that comes into contact with the water is poor, with a small inlet pipe diameter. During drainage, the suction force on impurities in the foundation pit water is too great, which easily leads to the suction of a large number of impurities being drawn in. This not only frequently causes blockage of the suction pipe, but also affects the drainage efficiency and reduces the stability of the device. Utility Model Content

[0004] The purpose of this invention is to provide a drainage device for construction water accumulation in deep foundation pits, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction water drainage device for deep foundation pits, comprising a water pump, a pumping pipe fixedly connected to the right side of the water pump, a fixing mechanism at the bottom of the pumping pipe, and an interception mechanism at the bottom of the fixing mechanism.

[0006] The fixing mechanism includes a suction bucket assembly, a positioning assembly, and a fixing assembly. The suction bucket assembly is located at the bottom of the liquid suction tube, the positioning assembly is located inside the top of the fixing mechanism, and the fixing assembly is located on the front and rear sides of the positioning assembly.

[0007] The interception mechanism includes a filtering component, a positioning component, and a disassembly component. The filtering component is located at the bottom of the suction bucket component, the positioning component is located on the front and rear sides of the filtering component, and the disassembly component is located inside the positioning component.

[0008] Preferably, the suction assembly includes a suction bucket, which is sleeved on the bottom of the outer ring of the liquid suction tube, and a sleeve is fixedly connected to the top of the suction bucket, which is sleeved on the outer ring of the liquid suction tube.

[0009] Preferably, the positioning assembly includes a fixing ring, which is fixedly connected to the outer ring of the suction tube. The fixing ring is fixedly connected to the left and right sides of the fixing ring, and the fixing plate is snapped into the top of the sleeve. The bottom of the fixing plate is fixedly connected to a locking plate, which is snapped into the top of the sleeve.

[0010] Preferably, the fixing component includes an insert plate, which is fixedly connected to the front and rear sides of the fixing ring and snapped into the top of the sleeve. A fixing screw is provided on the outer side of the insert plate and is fixedly connected to the front and rear sides of the sleeve. A bolt is threaded into the inner ring of the fixing screw and passes through the insert plate and snaps into the sleeve.

[0011] Preferably, the filter assembly includes a base, which is fixedly connected to the bottom of the suction hopper, and a frame is snapped into the bottom of the base, with a mesh plate fixedly connected inside the frame.

[0014] Compared with the prior art, this utility model provides a construction water drainage device for deep foundation pits, which has the following beneficial effects:

[0015] 1. This deep foundation pit construction water drainage device, through a fixed mechanism, has a suction bucket fitted onto the bottom of the outer ring of the suction pipe. This increases the inlet diameter of the suction pipe at the bottom of the suction pipe, reducing the suction force on impurities in the foundation pit water without changing the suction efficiency. This prevents some impurities from being attracted by the suction pipe, reducing the probability of blockage and increasing the stability of the device during use. At the same time, workers only need to rotate the bolts on the front and back sides to fix and disassemble the suction pipe and suction bucket, making it easy for workers to assemble and disassemble the device and the suction pipe. The operation is simple and convenient for workers to use.

[0016] 2. The deep foundation pit construction water drainage device uses an interception mechanism with a mesh screen at the bottom of the suction bucket to filter the liquid entering the bucket. This prevents large impurities from passing through the mesh screen and being drawn out by the suction pipe, effectively preventing damage to the water pump caused by solid impurities in the water, ensuring the service life of the water pump, reducing the failure rate during use, and preventing internal blockages in the water pump. Furthermore, workers can easily unlock the mesh screen by pulling a lever outwards, allowing them to replace the mesh screen with different mesh sizes as needed, increasing the device's versatility.

[0028] This utility model provides a technical solution:

[0029] Example 1

[0030] Combination Figures 1 to 6 A deep foundation pit construction water drainage device includes a water pump 3, a liquid extraction pipe 4 fixedly connected to the right side of the water pump 3, a fixing mechanism 1 at the bottom of the liquid extraction pipe 4, and an interception mechanism 2 at the bottom of the fixing mechanism 1.

[0031] The fixing mechanism 1 includes a suction bucket assembly 11, a positioning assembly 12, and a fixing assembly 13. The suction bucket assembly 11 is located at the bottom of the liquid suction tube 4, the positioning assembly 12 is located inside the top of the fixing mechanism 1, and the fixing assembly 13 is located on the front and rear sides of the positioning assembly 12.

[0032] The suction assembly 11 includes a suction cup 1101, which is fitted onto the bottom of the outer ring of the suction tube 4. A sleeve 1102 is fixedly connected to the top of the suction cup 1101, and the sleeve 1102 is fitted onto the outer ring of the suction tube 4. The locking assembly 12 includes a fixing ring 1201, which is fixedly connected to the outer ring of the suction tube 4. Insert plates 1202 are fixedly connected to the left and right sides of the fixing ring 1201, and the insert plates 1202 are locked into the top of the sleeve 1102. A locking plate 1203 is fixedly connected to the bottom of the insert plates 1202. The clamping plate 1203 is clamped inside the top of the sleeve 1102. The fixing component 13 includes an insert plate 1301, which is fixedly connected to the front and rear sides of the fixing ring 1201. The insert plate 1301 is clamped inside the top of the sleeve 1102. A fixing screw 1302 is provided on the outer side of the insert plate 1301. The fixing screw 1302 is fixedly connected to the front and rear sides of the sleeve 1102. A bolt 1303 is threaded on the inner ring of the fixing screw 1302. The bolt 1303 passes through the insert plate 1301 and is clamped inside the sleeve 1102.

[0033] Furthermore, the suction bucket 1101 is fitted onto the bottom of the outer ring of the suction pipe 4, increasing the inlet diameter of the suction pipe 4 for drawing liquid. This reduces the suction force on impurities in the pit water without changing the suction efficiency, preventing some impurities from being attracted by the suction pipe 4, reducing the probability of blockage, and increasing the stability of the device during use. At the same time, the operator only needs to rotate the bolts 1303 on the front and rear sides to fix and disassemble the suction pipe 4 and the suction bucket 1101, making it easy for the operator to assemble and disassemble the device and the suction pipe 4. The operation is simple and convenient for the operator to use.

[0034] Example 2

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 Furthermore, based on Embodiment 1, the interception mechanism 2 includes a filter assembly 21, a positioning assembly 22, and a disassembly assembly 23. The filter assembly 21 is disposed at the bottom of the suction assembly 11, the positioning assembly 22 is disposed on the front and rear sides of the filter assembly 21, and the disassembly assembly 23 is disposed inside the positioning assembly 22.

[0036] The filter assembly 21 includes a base 2101, which is fixedly connected to the bottom of the suction bucket 1101. A frame 2102 is snapped into the bottom of the base 2101, and a mesh plate 2103 is fixedly connected inside the frame 2102. The positioning assembly 22 includes a fixing box 2201, which is fixedly connected to the front and rear sides of the base 2101. A sliding plate 2202 is slidably connected inside the fixing box 2201, and a compression spring 2203 is fixedly connected to the outside of the sliding plate 2202. A compression spring 2203 is fixedly connected inside a fixed box 2201. A locking rod 2204 is fixedly connected to the inside of a slide plate 2202. The locking rod 2204 is engaged with the base 2101 and the front and rear sides of the frame 2102. The disassembly assembly 23 includes a telescopic slide rod 2301. The telescopic slide rod 2301 is fixedly connected to the outside of the slide plate 2202. The telescopic slide rod 2301 is slidably connected to the inside of the outside of the fixed box 2201. A pull rod 2302 is fixedly connected to the outside of the telescopic slide rod 2301.

[0037] Furthermore, the screen plate 2103 is located at the bottom of the suction bucket 1101 to filter the liquid entering the suction bucket 1101. This prevents large impurities from passing through the screen plate 2103 and being drawn out by the suction pipe 4, effectively preventing damage to the water pump 3 that may be caused by solid impurities in the accumulated water. This ensures the service life of the water pump 3, reduces the failure rate of the water pump 3 during use, and prevents blockage inside the water pump 3 during use. At the same time, the operator only needs to pull the lever 2302 outward to release the lock on the screen plate 2103, allowing the operator to replace the screen plate 2103 with different mesh sizes as needed to filter the accumulated water, increasing the applicability of the device.

[0038] In actual operation, when this device is in use and the suction bucket 1101 needs to be installed, the operator first inserts the bottom end of the suction tube 4 into the inner ring of the sleeve 1102, then rotates the suction tube 4 to align the clamping plate 1203 and the insert plate 1301 with the top of the sleeve 1102. Then, the operator moves the suction tube 4 downwards. The downward movement of the suction tube 4 causes the fixing ring 1201 to move downwards, which in turn causes the clamping plate 1203 and the insert plate 1301 to move downwards. 01. Move downwards, and the clamping plate 1203 and the insert plate 1301 move downwards and engage with the top of the sleeve 1102 until the fixing ring 1201 can no longer move downwards. At this time, the worker rotates the bolt 1303 into the fixing screw cylinder 1302. The bolt 1303 rotates and moves inwards in the inner ring of the fixing screw cylinder 1302. The bolt 1303 moves inwards, passes through the insert plate 1301, and engages with the sleeve 1102. At this time, the installation of the suction bucket 1101 is completed.

[0039] When it is necessary to disassemble the mesh panel 2103, the worker first pulls the front and rear levers 2302 outward. The outward movement of the levers 2302 drives the slide plate 2202 outward through the telescopic slide rod 2301. The outward movement of the slide plate 2202 drives the locking rod 2204 outward. The locking rod 2204 moves outward and retracts into the fixing box 2201, disconnecting it from the base 2101 and the frame 2102. Then, the frame 2102 can be moved downward to complete the disassembly of the mesh panel 2103. After that, the worker can attach the new mesh panel 2103 to the bottom of the base 2101 to fix the new mesh panel 2103 in place.
