Description

Technical Field

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

[0002] With the rapid development of the modern construction industry, high-rise and super high-rise buildings are becoming increasingly common. Due to their large superstructure loads, high-rise and super high-rise buildings mostly employ compensating foundations and typically include multiple basements to improve stability. However, this results in deep foundations and deep excavations. Especially in areas with high groundwater levels, deep excavations can disrupt the aquifer, allowing groundwater to continuously seep into the pit, causing quicksand, slope instability, or a decrease in the foundation's bearing capacity. Therefore, existing foundation pit construction typically incorporates drainage structures within the pit.

[0003] Existing drainage systems typically use water pumps for drainage. In actual use, silt and debris can enter the foundation pit along with the water flow. When the water in the foundation pit is pumped out, the pumping pipe becomes blocked due to the silt and debris, thus affecting normal drainage. Therefore, we propose a deep foundation pit drainage structure to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a deep foundation pit drainage structure, which solves the problem that in actual use, silt and debris will enter the foundation pit along with the water flow, and when the water in the foundation pit is pumped out, the end of the pumping pipe will be blocked due to the entry of silt and debris, thus affecting normal drainage.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a deep foundation pit drainage structure, comprising a deep foundation pit body, wherein a water pump is fixedly installed on the top of the deep foundation pit body;

[0006] The input end of the water pump is fixedly connected to a water pumping pipe;

[0007] The bottom of the inner cavity of the deep foundation pit is fixedly installed with a primary filter cartridge for preliminary filtration of large garbage impurities;

[0008] A secondary filter cartridge for secondary filtration of fine silt is fixedly installed at the end of the pumping pipe away from the pumping pump.

[0009] Preferably, one end of the pumping pipe extends into the interior of the primary filter cartridge and is fixedly connected to the primary filter cartridge, and the secondary filter cartridge is located inside the primary filter cartridge.

[0010] Preferably, an L-shaped plate is fixedly installed at the top of the deep foundation pit body near the water pump position. A motor is fixedly installed on the surface of the L-shaped plate by bolts. A rotating disk is fixed to the output end of the motor. A fixing column is fixedly installed on the non-center surface of the rotating disk. An installation ring is rotated on the surface of the fixing column by bearings. A rope is fixed on the surface of the installation ring.

[0011] The primary filter cartridge has a sleeve inside, and a brush tube is installed inside the sleeve. A connecting rod is fixed to the surface of the sleeve, and the end of the rope away from the mounting ring is fixedly connected to the connecting rod.

[0012] Preferably, the top of the primary filter cartridge is provided with a limiting sliding hole that matches the connecting rod. The connecting rod and the primary filter cartridge are slidably connected through the limiting sliding hole. The brush cylinder is located above the secondary filter cartridge and is designed to be concentrically aligned.

[0013] Preferably, the sleeve is threaded with multiple sets of locking bolts through threaded holes. The locking bolts are used to press the brush tube to achieve the connection and locking between the brush tube and the sleeve.

[0014] Preferably, a weighted ring is fixedly fitted onto the outer surface of the sleeve.

[0015] Preferably, a limiting ring rod is fixed to the surface of the L-shaped plate, and the rope moves within the annular hole of the limiting ring rod.

[0016] Beneficial effects

[0017] This utility model provides a drainage structure for deep foundation pits. Compared with the prior art, it has the following advantages:

[0018] This deep pit drainage structure features a primary filter cartridge with a large pore size, which effectively filters out larger particles of silt and debris, preventing them from entering the water pump and pumping pipes. This reduces wear and clogging risks on the pump. Because the primary filter cartridge filters first, the secondary filter cartridge bears less load and only needs to filter finer particles. This extends the service life of the secondary filter cartridge, reduces replacement frequency and maintenance costs. The two-stage filtration system reduces clogging in the pumping pipes, thus maintaining efficient pumping, improving pumping efficiency, ensuring proper drainage, and enhancing the overall effectiveness of the system.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown:

[0025] A deep foundation pit drainage structure includes a deep foundation pit body 101.

[0026] In this implementation plan: To solve the technical problems existing in the prior art, such as the above-disclosed background technology, "the existing drainage device usually uses a water pump 102 for drainage. In actual use, mud and debris will enter the foundation pit along with the water flow. When the water in the foundation pit is pumped out, the end of the pumping pipe 103 is blocked due to the entry of mud and debris, thus affecting normal drainage." In combination with the use, this problem is obviously a real and difficult problem to solve. All electrical equipment involved in this product is powered by an external power source.

[0027] Furthermore:

[0028] like Figures 1-3 As shown:

[0029] Based on the above: A water pump 102 is fixedly installed on the top of the main body 101 of the deep foundation pit;

[0030] The input end of the water pump 102 is fixedly connected to the water pump pipe 103;

[0031] A primary filter cartridge 105 for preliminary filtration of large garbage and impurities is fixedly installed at the bottom of the inner cavity of the deep foundation pit body 101.

[0032] A secondary filter cartridge 104 for secondary filtration of fine silt is fixedly installed at the end of the water pump 103 away from the water pump 102.

[0033] One end of the water pumping pipe 103 extends into the interior of the primary filter cartridge 105 and is fixedly connected to the primary filter cartridge 105. The secondary filter cartridge 104 is located inside the primary filter cartridge 105, and the filtration aperture of the primary filter cartridge 105 is larger than that of the secondary filter cartridge 104.

[0034] In this implementation plan: When the deep foundation pit drainage structure is in use, it is necessary to drain the water inside the deep foundation pit body 101;

[0035] By starting the water pump 102, the water inside the deep foundation pit body 101 is discharged through the water pumping pipe 103.

[0036] A primary filter cartridge 105 is fixed at the bottom of the inner cavity of the deep foundation pit body 101. The primary filter cartridge 105 can initially filter a large amount of garbage in the water in the inner cavity, while the secondary filter cartridge 104 can filter the mud and sand in the water.

[0037] The primary filter cartridge 105 has a larger pore size, which can filter out larger silt and debris first, preventing these larger particles from entering the water pump 102 and the water pipe 103. This reduces the risk of wear and blockage to the water pump 102. Because the primary filter cartridge 105 filters first, the secondary filter cartridge 104 bears a smaller load and only needs to filter finer particles. This can extend the service life of the secondary filter cartridge 104, reduce the frequency of replacement and maintenance costs. Through the two-stage filtration system, blockage in the water pipe 103 can be reduced, thereby maintaining the efficient operation of the water pump 102, improving the pumping efficiency, maintaining normal drainage effect, and improving the overall performance of the device.

[0038] Furthermore;

[0039] In an optional embodiment, an L-shaped plate 106 is fixedly installed at the top of the deep foundation pit body 101 near the water pump 102. A motor 107 is fixedly installed on the surface of the L-shaped plate 106 by bolts. A rotating disk 108 is fixed to the output end of the motor 107. A fixing column 109 is fixedly installed on the non-center surface of the rotating disk 108. An installation ring 110 rotates on the surface of the fixing column 109 through a bearing. A rope 111 is fixed to the surface of the installation ring 110.

[0040] The primary filter cartridge 105 has a sleeve 114 inside, and a brush tube 115 is installed inside the sleeve 114. A connecting rod 113 is fixed to the surface of the sleeve 114. The end of the rope 111 away from the mounting ring 110 is fixedly connected to the connecting rod 113.

[0041] The top of the primary filter cartridge 105 is provided with a limiting sliding hole that matches the connecting rod 113. The connecting rod 113 and the primary filter cartridge 105 are slidably connected through the limiting sliding hole. The brush cylinder 115 is located above the secondary filter cartridge 104 and is designed to be concentrically aligned.

[0042] In this embodiment: the motor 107 on the L-shaped plate 106 is started at the same time. The operation of the motor 107 drives the rotating disk 108 to rotate, which in turn drives the fixed column 109 to rotate. The fixed column 109 drives the mounting ring 110 to rotate synchronously. The fixed column 109 drives the rope 111 to reciprocate to lift and release. The mounting ring 110 can rotate on the fixed column 109, thereby avoiding the rope 111 from getting tangled on the fixed column 109.

[0043] By lifting and releasing the rope 111, the connecting rod 113 is driven to move up and down on the primary filter cartridge 105. The connecting rod 113 drives the sleeve 114 to move, and the sleeve 114 drives the brush cylinder 115 to move. The brush cylinder 115 moves to the position of the secondary filter cartridge 104. As the brush cylinder 115 moves up and down, it cleans the mud and sand adhering to the secondary filter cartridge 104, which helps to keep the surface of the secondary filter cartridge 104 clean, prevents the filter pores from being blocked, and thus maintains the filtration efficiency of the secondary filter cartridge 104.

[0044] It should be noted that the solution also includes an electrical control cabinet, which is installed on the L-shaped plate 106. During use, each electrical device can be started and operated separately through the electrical control cabinet. The power connection method of each electrical device is an existing mature technology and is well known to those in the field, so it will not be elaborated further here.

[0045] Furthermore;

[0046] In an optional embodiment, the sleeve 114 is threaded with multiple sets of locking bolts 116 through threaded holes. The locking bolts 116 are used to press the brush cylinder 115 to achieve the connection and locking of the brush cylinder 115 and the sleeve 114.

[0047] In this embodiment, the brush tube 115 is mounted on the sleeve 114 by a locking bolt 116. With prolonged use, when the brush tube 115 is to be removed and replaced, the locking bolt 116 is rotated to release the pressure on the brush tube 115, thereby releasing the lock between the sleeve 114 and the brush tube 115, thus facilitating the replacement of the brush tube 115.

[0048] Furthermore;

[0049] In an optional embodiment, a weighted ring 117 is fixedly fitted onto the outer surface of the sleeve 114.

[0050] In this embodiment, a weight ring 117 is fixed on the surface of the sleeve 114. The weight ring 117 can increase the overall weight of the sleeve 114, making it easier for the sleeve 114 to move down more stably when the rope 111 is released.

[0051] Furthermore;

[0052] In an optional embodiment, a limiting ring rod 112 is fixed to the surface of the L-shaped plate 106, and the rope 111 is limited to move within the annular hole of the limiting ring rod 112.

[0053] In this embodiment: when the fixed column 109 drives the rope 111 to reciprocate to lift and release, the rope 111 can move within the annular hole of the limiting ring rod 112, thereby limiting the rope 111 and enabling the rope 111 to be transported better.

[0054] The working principle and usage process of this utility model are as follows: When the water inside the deep foundation pit body 101 needs to be discharged, the water is discharged through the pump 102 and then through the pumping pipe 103. A primary filter cartridge 105 is fixed at the bottom of the inner cavity of the deep foundation pit body 101. The primary filter cartridge 105 can initially filter out a large amount of garbage in the water in the inner cavity, and the secondary filter cartridge 104 can further filter out the mud and sand in the water. The filter pores of the primary filter cartridge 105 are relatively large, which can first filter out larger mud and sand and debris, preventing these larger particles from entering the pump 102 and the pumping pipe 103, and reducing the blockage in the pumping pipe 103. Simultaneously, the motor 107 on the L-shaped plate 106 is started. The operation of the motor 107 drives the rotating disk 108 to rotate, which in turn drives the fixed column 109 to rotate. The fixed column 109 drives the mounting ring 110 to rotate synchronously. The fixed column 109 drives the rope 111 to reciprocate in lifting and releasing. By lifting and releasing the rope 111, the connecting rod 113 moves up and down on the primary filter cartridge 105. The connecting rod 113 drives the sleeve 114 to move, and the sleeve 114 drives the brush cylinder 115 to move. The brush cylinder 115 moves to the position of the secondary filter cartridge 104. As the brush cylinder 115 moves up and down, it cleans the mud and sand adhering to the secondary filter cartridge 104.

[0055] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
