Description

Technical Field

[0001] This patent relates to the field of foundation pit drainage technology, specifically a deep foundation pit drainage structure. Background Technology

[0002] There are generally two reasons for water accumulation in foundation pits: one is the subsidence of surface precipitation or drainage, and the other is water inrush, i.e., the rise of groundwater. If the drainage of foundation pits is not handled properly, it can easily lead to landslides or even collapses around the pit, resulting in serious construction accidents and huge economic losses.

[0003] In existing methods of draining deep foundation pits, a water pump is typically placed inside the pit to pump out the water. However, if the water level in the pit completely submerges the pump, and the pump's electrical wires are damaged or poorly bonded, leakage is very likely to occur. If workers are in direct contact with the water inside the pit, they are at risk of electric shock. Utility Model Content

[0004] The purpose of this patent is to provide a deep foundation pit drainage structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this patent provides the following technical solution: a deep foundation pit drainage structure, including a water pump and a plug rod, wherein a drainage pipe is installed at the output end of the water pump, and a protective pad is sleeved on the outside of the input end of the water pump, and the protective pad can float above the water surface of the external foundation pit.

[0006] A fixing block is installed on the side wall of the insertion rod, and a sliding groove is opened on the side wall of the fixing block. One end of the sliding rod is slidably installed in the sliding groove, and the other end of the sliding rod is installed on the side wall of the water pump.

[0007] A fixing cylinder is inserted into the lower wall of the protective pad. The inner wall of the fixing cylinder is provided with internal threads. A filter cylinder is installed inside the fixing cylinder through the threads. The filter cylinder is connected to the input end of the water pump. The filter cylinder can filter the water in the external foundation pit.

[0008] Preferably, the protective pad includes a main board, a slot, a mounting bracket, a fixing shaft, and a sub-board. The upper wall of the main board has a slot, and the input end of the water pump and the fixing cylinder are both inserted into the slot. Mounting brackets are installed on both the front and rear sides of the lower wall of the main board. There are two sub-boards, and the side walls of the two sub-boards have mounting holes. The fixing shaft is inserted into the mounting holes, and the two fixing shafts are respectively installed on the inner walls of the two mounting brackets.

[0009] Preferably, the sliding rod includes a rod body, a ball head, a slider, and a spherical groove. The slider is slidably installed in the groove, and the side wall of the slider has a spherical groove. One end of the rod body is installed on the side wall of the water pump, and the other end of the rod body is installed with a ball head, which is inserted into the spherical groove.

[0010] Preferably, the insertion rod includes a main cylinder, a secondary cylinder, a positioning pin, and a positioning hole. The secondary cylinder is slidably installed inside the main cylinder. A positioning hole is provided on the side wall of the secondary cylinder. A positioning pin is inserted into the side wall of the main cylinder. The positioning pin can be inserted into the positioning hole.

[0011] Preferably, the lower wall of the main body is fitted with a pin that can be inserted into the external pit, and the upper wall of the auxiliary body is fitted with a handle.

[0012] Preferably, both the main board and the sub-board are made of foam board.

[0013] Compared with existing technologies, the beneficial effects of this patent are:

[0014] This device features a protective pad placed below the water pump, which floats on the water surface, preventing the main body of the water pump from contacting the water in the pit. This avoids pump damage or electrical leakage, making drainage construction safer. In addition, the device also has a sub-plate below the protective pad. By unfolding the sub-plate, the contact area between the protective pad and the water surface can be increased, thus increasing the buoyancy of the protective pad.

[0015] In addition, this device is equipped with a filter cylinder, which can block debris or large particles of sand and gravel in the foundation pit water, preventing impurities from entering the water pump and causing damage to the pump blades. Attached Figure Description

[0021] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] Please see Figure 1-4 This patent provides a technical solution: a deep foundation pit drainage structure, including a water pump 1 and a plug rod 2. A drainage pipe 3 is installed at the output end of the water pump 1, and a protective pad 4 is sleeved on the outside of the input end of the water pump 1. The protective pad 4 can float above the water surface of the external foundation pit.

[0023] A fixing block 5 is installed on the side wall of the insertion rod 2. A sliding groove 6 is opened on the side wall of the fixing block 5. One end of the sliding rod 7 is slidably installed in the sliding groove 6, and the other end of the sliding rod 7 is installed on the side wall of the water pump 1.

[0024] A fixing cylinder 8 is inserted into the lower wall of the protective pad 4. The inner wall of the fixing cylinder 8 is provided with internal threads. A filter cylinder 9 is installed inside the fixing cylinder 8 through the threads. The filter cylinder 9 is connected to the input end of the water pump 1. The filter cylinder 9 can filter the water in the external foundation pit.

[0025] By setting up the protective pad 4, the water pump 1 can float on the water surface of the foundation pit, preventing water from entering the water pump 1, which would damage the internal circuit structure and delay the drainage work of the deep foundation pit.

[0026] Since the drainage structure proposed in this paper is used in deep foundation pits, which are difficult for workers to climb up and down due to their depth, this device is designed with insert rod 2 to allow it to be easily placed into the deep foundation pit without requiring workers to enter the pit.

[0027] The filter cartridge 9 can block impurities or large particles of sand and gravel in the water, preventing impurities from entering the water pump 1 and damaging the blades of the water pump 1.

[0028] Specifically, the protective pad 4 includes a main board 41, a slot 42, a mounting bracket 43, a fixing shaft 44, and a sub-board 45. The upper wall of the main board 41 has a slot 42, and the input end of the water pump 1 and the fixing cylinder 8 are both inserted into the slot 42. Mounting brackets 43 are installed on both the front and rear sides of the lower wall of the main board 41. There are two sub-boards 45. The side walls of the two sub-boards 45 have mounting holes 10, and the fixing shafts 44 are inserted into the mounting holes 10. The two fixing shafts 44 are respectively installed on the inner walls of the two mounting brackets 43.

[0029] In order to improve the buoyancy of the protective pad 4 and prevent the device from sinking, the device has rotatable sub-plates 45 on both the front and rear sides of the main board 41. The sub-plates 45 increase the contact area between the protective pad 4 and the water surface, thereby making the device more stable when placed on the water surface.

[0030] Specifically, the sliding rod 7 includes a rod body 71, a ball head 72, a slider 73, and a spherical groove 74. The slider 73 is slidably installed in the sliding groove 6. The side wall of the slider 73 is provided with a spherical groove 74. One end of the rod body 71 is installed on the side wall of the water pump 1, and the other end of the rod body 71 is provided with a ball head 72. The ball head 72 is inserted into the spherical groove 74.

[0031] Since it cannot be guaranteed that the water surface in the pit will be calm, the sliding rod 7 is designed as a split structure, so that the rod 71 and the slider 73 are connected by the ball head 72 and the spherical groove 74, so that the protective pad 4 and the water pump 1 above can rise and fall with the water surface.

[0032] Specifically, the insertion rod 2 includes a main cylinder 21, a secondary cylinder 22, a positioning pin 23, and a positioning hole 24. The secondary cylinder 22 is slidably installed inside the main cylinder 21. The side wall of the secondary cylinder 22 is provided with a positioning hole 24. The side wall of the main cylinder 21 is inserted with a positioning pin 23, which can be inserted into the positioning hole 24.

[0033] The insertion rod 2 in this article can adjust its length to adapt to foundation pits of different depths.

[0034] Specifically, the lower wall of the main cylinder 21 is equipped with a pin 11, which can be inserted into the external pit, and the upper wall of the auxiliary cylinder 22 is equipped with a handle 12.

[0035] Specifically, both the main board 41 and the sub-board 45 are made of foam board;

[0036] The foam board is key to the protective pad 4 floating on the water.

[0037] Working principle: The water pump 1 and the protective pad 4 are placed into the pit through the insertion rod 2. At this time, under the action of the protective pad 4, the device can float on the water surface. Then, the insertion rod 2 is inserted downward to insert the pin 11 into the bottom of the pit. Then, the water pump 1 is connected to the power supply and started to pump out the water in the pit and discharge it through the drain pipe 3. As the water level drops, the sliding rod 7 will also slide in the groove 6 until all the water in the pit is pumped out.

[0038] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
