Technical Field
[0001] The utility model relates to the field of foundation pit drainage, and particularly to a deep foundation pit drainage device. Background Art
[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. Before excavation, the excavation plan should be determined based on geological and hydrological data, combined with the situation of nearby buildings on site, and waterproof and drainage work should be done well. The deep foundation pit support structure refers to the support structure adopted for the bottom wall of the deep foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the deep foundation pit.
[0003] Due to rainfall and precipitation, deep foundation pits are prone to water accumulation. Water accumulation soaking the deep foundation pit will cause serious safety hazards, including but not limited to damage to the deep foundation pit support structure, instability and collapse of the deep foundation pit, etc. Therefore, in actual engineering, in order to ensure safety, it is necessary to drain the accumulated water in the deep foundation pit in time. The existing deep foundation pit drainage method is mainly that the staff place the drainage device in the sump of the deep foundation pit, and then observe at any time whether there is water accumulation in the deep foundation pit. If water accumulation forms, the drainage device is manually started to drain water. This drainage method requires the staff to observe at any time whether water accumulation forms, and in the case of water accumulation, the drainage device has to be manually started, which not only wastes manpower but also has low drainage efficiency.
[0004] Therefore, a deep foundation pit drainage device is proposed to solve the above problems. Content of the Utility Model

[0022] Embodiment:
[0023] See Figures 1 to 3 , a deep foundation pit drainage device of the present utility model includes a water suction pump 2; the water suction pump 2 is placed in the sump pit 6 of the deep foundation pit 5, the water suction pump 2 is connected with a water outlet pipe 3 and the end of the water outlet pipe 3 far from the water suction pump 2 is located outside the deep foundation pit 5; the water suction pump 2 is also connected with a water inlet pipe 4, and the water inlet pipe 4 is located in the sump pit.

[0025] It also includes a horizontal sliding pressure plate 801 and a spring 802; the lower end of the spring 802 is connected to the bottom of the groove 8 and the upper end is connected to the horizontal sliding pressure plate 801; in the initial state of the spring 802, the side of the horizontal sliding pressure plate 801 fits against the inner side of the groove 8 and the horizontal sliding pressure plate 801 is lower than the top surface of the horizontal bottom plate 7; the horizontal sliding pressure plate 801 is connected downward with an ejector rod 803, and the bottom of the groove 8 is connected upward with a touch switch 804, and the ejector rod 803 points to the touch switch 804; the touch switch 804 is used to control the opening of the water suction pump 2;
[0026] When the space between the top surface of the horizontal sliding pressure plate 801 and the top surface of the horizontal bottom plate 7 in the groove 8 is gradually filled with water, the weight of the water causes the spring 802 to compress, and the ejector rod 803 presses against and turns on the touch switch 804.
[0027] In this embodiment, when there is accumulated water in the deep foundation pit 5, the accumulated water will be drained into the sump pit 6; when the accumulated water in the sump pit 6 overflows the top surface of the horizontal bottom plate 7, the accumulated water enters the groove 8; when the space between the top surface of the horizontal sliding pressure plate 801 and the top surface of the horizontal bottom plate 7 in the groove 8 is gradually filled with water, the weight of the water causes the spring 802 to compress, the ejector rod 803 to hold against and turn on the touch switch 804, and the touch switch 804 controls the suction pump 2 to turn on; the suction pump 2 absorbs the accumulated water through the water inlet pipe 4 and then discharges the accumulated water to the outside of the deep foundation pit 5 through the water outlet pipe 3. During this process, there is no need to specifically arrange personnel to observe whether there is accumulated water in the deep foundation pit 5, saving manpower; and, by triggering the touch switch 804 after the accumulated water enters the sump pit 6 to turn on the suction pump 2, the accumulated water can be discharged in a timely manner, improving the drainage efficiency.
[0028] As a preferred embodiment, refer to Figures 1 to 2 , the water outlet pipe 3 is connected to the vertical plate 1.
[0029] In this embodiment, the connection between the water outlet pipe 3 and the vertical plate 1 makes the water outlet pipe 3 more stable during the drainage process when the accumulated water passes through the water outlet pipe 3.
[0030] As a preferred embodiment, refer to Figures 1 to 2 , it further includes a water outlet box 9; the water outlet box 9 is communicated with one end of the water outlet pipe 3 far from the suction pump 2, and a plurality of water outlet holes are opened on one side of the water outlet box 9 far from the water outlet pipe 3.
[0031] In this embodiment, by utilizing the function of opening a plurality of water outlet holes on one side of the water outlet box 9, the accumulated water sprayed to the outside of the deep foundation pit 5 is sprayed in an atomized state, reducing the situation that the sprayed accumulated water accumulates into a water pit outside the deep foundation pit 5.
[0032] As a preferred embodiment, refer to Figures 1 to 2 , a filter screen 10 is provided at one end of the water inlet pipe 4 far from the suction pump 2.
[0033] In this embodiment, the filter screen 10 can filter stones and other impurities existing in the accumulated water, avoiding the blockage of the water inlet pipe 4.
[0034] As a preferred embodiment, refer to Figures 1 to 3 , a drain hole 11 is opened on the side wall of the groove 8, and the groove 8 is communicated with the sump pit 6 through the drain hole 11;
[0035] In the initial state of the spring 802, the drain hole 11 is located between the top surface of the horizontal sliding pressure plate 801 and the top surface of the horizontal bottom plate 7; during the pumping operation of the suction pump 2, the drain hole 11 causes the water level between the top surface of the horizontal sliding pressure plate 801 and the top surface of the horizontal bottom plate 7 to gradually drop until, under the action of the spring 802, the ejector rod 803 disengages from the touch switch 804.
[0036] In this embodiment, during the process of discharging accumulated water through the water suction pump 2, when the water level of the accumulated water drops to the top surface of the horizontal bottom plate 7, since the drain hole 11 enables the groove 8 to communicate with the sump 6, when the water suction pump 2 continues to drain the sump 6, the water level in the groove 8 will also drop. Until when the rebounding force of the spring 802 is greater than the sum of the gravity of the accumulated water in the groove 8 and the horizontal sliding pressure plate 801, under the action of the rebounding force of the spring 802, the ejector rod 803 disengages from the touch switch 804, causing the water suction pump 2 to stop working. In this way, the water suction pump 2 is prevented from idling continuously. At this time, there is no accumulated water in the deep foundation pit 5 anymore, and the purpose of drainage has been completed. Only the accumulated water remains in the sump 6, which does not affect the safety of the entire large deep foundation pit 5. The remaining accumulated water in the sump 6 can be manually drained by restarting the water suction pump 2 again.
