Description

Technical Field

[0001] The present application relates to the technical field of deep foundation pit drainage, and in particular to a deep foundation pit drainage device. Background Art

[0002] The foundation pit refers to the space below the ground excavated for the construction of the building foundation and basement. Since the construction process of the foundation pit is long and the subsequent building construction process is also long, if it rains during the construction process, a large amount of water will accumulate in the foundation pit. Therefore, drainage work needs to be done after the foundation pit construction, and the deep foundation pit drainage equipment is a device designed for this type of work.

[0003] Compared with the actual use process, one of the existing deep foundation pit drainage equipment uses a water pump to discharge the sewage at the bottom. Since there will be a lot of mud and sand in the foundation pit, the mud and sand will clog the water pipes and water pumps, causing pumping interruption, so a filter mechanism will be connected to the water inlet end of the water pump. However, after a long period of operation, the filter mechanism will still be clogged. At this time, the equipment needs to be shut down and the filter mechanism needs to be fished out and cleaned, which is very troublesome and will reduce operating efficiency.

[0004] Therefore, in order to solve the above problems, the present application provides a deep foundation pit drainage device.

[0018] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0019] Embodiment 1

[0020] Reference Figure 1-Figure 3A deep foundation pit drainage device comprises an isolation cover 1, an inner cover 2 is welded to the bottom inner end of the isolation cover 1, three spiral grooves 3 are provided on the outer surface of the inner cover 2, a rotating ring 4 is embedded at the top end of the inner cover 2, three sliders 15 are welded to the inner side of the rotating ring 4 in order to clean the filtering mechanism, the sliders 15 are slidably embedded in the inner side of the spiral groove 3, a rotating groove 5 is provided on the outer side of the rotating ring 4 in order to enable the rotating ring 4 to spirally slide down, a push-down plate 6 is embedded on the outer side of the rotating ring 4 on the inner side of the rotating groove 5, three support rods 7 are welded to the bottom inner end of the isolation cover 1, a waterproof cylinder 8 is installed at the top end of the support rod 7 through the base, the extended end of the waterproof cylinder 8 is connected to a gas spring seat 9, and the gas spring seat 9 One end is fitted with the top of the push-down plate 6. In order to play a buffering role, a connector 10 is fixed to the top of the inner cover 2 by bolts. The water outlet end of the connector 10 is connected to an outlet pipe 11. A positioning and fixing cover 12 is welded to the top of the waterproof cylinder 8. The outlet pipe 11 penetrates from one side of the positioning and fixing cover 12 and exits from the top of the positioning and fixing cover 12, and a hole is opened on the outside of the positioning and fixing cover 12. A water pump 13 is placed on the outside of the isolation cover 1. The water inlet end of the water pump 13 is connected to an inlet pipe 14. The power input end of the water pump 13 is connected to the power output end of the external control terminal. The inner diameter of the connector 10 is smaller than the inner diameter of the inner cover 2, and the outlet pipe 11 penetrates the isolation cover 1 and is connected to the inlet pipe 14.

[0021] Working principle: First, the operator connects the outlet pipe 11 with the inlet pipe 14 at the water inlet end of the water pump 13. The length of the inlet pipe 14 can be determined according to the situation. Then, the isolation cover 1 is placed at a deeper position in the foundation pit. After the placement is completed, the water pump 13 is started. At that time, the water pump 13 will absorb water through the inlet pipe 14, and the inlet pipe 14 will absorb water from the outlet pipe 11. The outlet pipe 11 will absorb water from the inner cover 2 through the connector 10 connected thereto. The inner cover 2 will absorb the water that has been initially filtered by the isolation cover 1, thereby achieving the effect of pumping water outwards. During the pumping period, the isolation cover 1 will filter and block large stones and other impurities in the foundation pit, and at the same time isolate the silt from the inner cover 2, so that the filtering effect of the inner cover 2 can be more durable, so that the pumping operation can last longer;

[0022] However, as time goes by, a layer of impurities will still adhere to the outside of the inner cover 2. As more and more impurities adhere, the water intake of the inner cover 2 will become smaller and smaller. At that time, the operator can observe that the drainage volume of the water pump 13 decreases. At this time, the operator needs to start the waterproof cylinder 8, and the waterproof cylinder 8 will push the gas spring seat 9 connected to the extension end, and the gas spring seat 9 will push the lower push plate 6 in contact with the bottom end to slide downward, and the rotating ring 4 embedded in the inner side of the lower push plate 6 will scrape and clean from the top of the inner cover 2 to the bottom of the inner cover 2. Due to the sliding block 15 welded on the inner side of the rotating ring 4, the spiral slide groove 3 opened on the outer side of the inner cover 2 is slidably embedded Because of the inner side, the rotating ring 4 will spirally scrape and clean the outer side of the inner cover 2, so that those more solid impurities can be removed. During this period, the gas spring seat 9 can reduce the impact force of the push-down plate 6 on the inner bottom end of the isolation cover 1 when the waterproof cylinder 8 indirectly pushes the push-down plate 6, thereby increasing the service life of the device. The operator needs to start and reset the waterproof cylinder 8 several times until the water output at the outlet end of the water pump 13 returns to normal, and then the waterproof cylinder 8 can be closed. This arrangement allows the device to be cleaned without shutting down the equipment when blockage occurs at the pumping end, which is very troublesome and can also speed up work efficiency.

[0023] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
