Description

Technical Field

[0001] This utility model relates to the field of support and drainage technology, and in particular to a support and sand and gravel barrier protection structure for a pit water collection well. Background Technology

[0002] During the excavation of foundation pits in building construction or municipal engineering projects, in order to remove accumulated water (such as groundwater, rainwater, etc.) in the pit in a timely manner, a sump is usually set up at the lowest point of the foundation pit, and a water pump is used to pump out the water.

[0003] Currently, most water collection wells at construction sites are temporary earthen pits, presenting the following technical problems: First, the well walls are exposed soil, which is prone to collapse and deformation under prolonged water immersion and the impact of water flow during pumping. This not only affects the normal use of the water collection well but may also pose a safety hazard to the overall stability of the foundation pit. Second, the water accumulating in the foundation pit carries a large amount of mud, sand, stones, and other debris as it flows into the water collection well. When these debris are sucked into the pump, they can easily cause wear on the pump impeller, blockage of pipes, and even burn out the motor, leading to reduced drainage efficiency, frequent equipment damage, increased maintenance costs, and the risk of work stoppage. Finally, the drainage ditches connecting the water collection wells are usually also earthen ditches. Under the scouring of rainwater or surface runoff, these ditches are easily eroded and widened, and the water flow can wash away the soil at the edge of the foundation pit. Over time, this may lead to slope instability and safety accidents. Utility Model Content

[0004] The purpose of this utility model is to provide a support and sand and gravel barrier protection structure for pit sump wells, which solves the problems in the prior art where sump wells are prone to collapse due to water flow impact, sand and gravel in the water can easily clog and damage water pumps, and drainage ditches are easily eroded, leading to instability at the edge of the foundation pit.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a support and gravel barrier protection structure for a pit-filled water collection well, the support and gravel barrier protection structure for the pit-filled water collection well comprising: The support is installed in the water collection well of the foundation pit. The support includes a side plate, a top plate, and a bottom plate. The side plate, top plate, and bottom plate are connected to each other to form a square box structure. The side plate is close to the side wall of the water collection well. Drainage holes are provided on both the side plate and the top plate. A socket-type drainage ditch is installed in the drainage ditch of the foundation pit, covers the drainage ditch, and is connected to the collection well.

[0006] In one embodiment, the top of the side plate is hinged to the top plate, the side plate is provided with a slide rail, the upper end of the slide rail extends to the top of the side plate, and the bottom plate is slidably fitted onto the slide rail of the side plate.

[0007] In one embodiment, a support block is provided on the inner side of the side plate, and the top of the support block is flush with the bottom of the slide.

[0008] In one embodiment, a lifting ring is provided on the base plate.

[0009] In one embodiment, the plug-in drainage channel comprises multiple channel bodies, a filter baffle, and anchor nails.

[0011] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages: The supporting and gravel barrier protection structure for pit sump wells provided in this embodiment of the utility model effectively supports the side walls of the sump well by setting up a supporting part and using a square box structure formed by side plates, top plates, and bottom plates, thus preventing the well wall from collapsing due to long-term water accumulation and water flow impact. At the same time, a socket-type drainage ditch covers the drainage ditch, guiding the water flow into the sump well in an orderly manner, effectively preventing the water flow from directly scouring the drainage ditch and the edge of the pit, and ensuring the overall stability of the pit.

[0012] In addition, drainage holes are provided on the side and top plates of the support structure to initially filter the water entering the collection well and block large pieces of sand and gravel. The plug-in drainage channel has filter baffles at the connection points, which also filter the water flow. This dual filtration design significantly reduces the amount of sand and gravel entering the collection well, effectively preventing blockages and damage to the water pump caused by sucking in debris, and ensuring the stable operation of the drainage system.

[0020] Please see Figures 1 to 3 This application provides a support and gravel barrier protection structure for a pit sump well, including a support part 1 and a socket-type drainage ditch 2.

[0021] The support unit 1 is installed inside the pre-excavated foundation pit 3's sump. The support unit 1 consists of interconnected side plates 11, a top plate 12, and a bottom plate 13, forming a square box structure. During installation, the side plates 11 of this box structure are tightly fitted against the soil sidewalls of the sump, providing reliable support and preventing collapse. Drainage holes 14 are densely arranged on both the side plates 11 and the top plate 12. The diameter of these drainage holes 14 is designed to ensure that water from the foundation pit 3 flows smoothly into the support unit 1 while blocking larger particles of sand and gravel. The water pump placed inside the support unit 1 (i.e., on the bottom plate 13) is thus effectively protected.

[0022] A socket-type drainage guide ditch 2 is installed above the pre-designed drainage ditch within the foundation pit 3, directly covering the ditch and connecting to the opening of the collection well. The socket-type drainage guide ditch 2 slopes downwards towards the collection well, with a specific inclination angle of 2°. This allows surface runoff (such as rainwater) within the foundation pit 3 to be guided through the socket-type drainage guide ditch 2 and ultimately flow into the collection well. The water flow within the guide ditch avoids direct erosion of the soil at the bottom of the ditch, thus protecting the stability of the ditch and the edges of the foundation pit 3.

[0023] In one specific embodiment, the support 1 is designed to be foldable for easy transportation and installation. Specifically, the top of the side plate 11 is hinged to the top plate 12 via hinges or other means. Each side plate 11 has a vertical slide rail 111 on its inner wall, with an opening at the top and extending to the top of the side plate 11. The edge of the bottom plate 13 is designed to slide and engage with the slide rail 111 of the side plate 11. During installation, the bottom plate 13 is slid into the slide rail 111 from the top until it reaches the bottom. To increase the stability of the bottom plate 13, a support block 112 is provided on the inner side of the side plate 11 at the bottom of the slide rail 111. When the bottom plate 13 slides into place, its bottom surface is supported by the support block 112. During disassembly, the base plate 13 is lifted up to the top along the slide rail 111 by the lifting ring 15 (e.g., a hook) provided on the base plate 13. Then, each side plate 11 can be rotated and folded inward to close the entire support part 1, greatly reducing the space it occupies.

[0024] In one specific embodiment, the socket-type drainage channel 2 consists of multiple standardized channel bodies 21, filter baffles 22, and anchor nails 23. Each channel body 21 is a U-shaped water trough structure, with one end being a slightly larger diameter receiving end 211 and the other end being a slightly smaller diameter insertion end 212. During installation, the insertion end 212 of one channel body 21 is inserted into the receiving end 211 of the adjacent channel body 21 for quick connection, and any length can be spliced ​​as needed. In the mating area between the receiving end 211 and the insertion end 212, a detachable or fixed filter baffle 22 is provided. When water flows through this area, fine sand and gravel are further filtered, improving the protection effect on the water pump. To ensure the stability of the channel on the ground of the foundation pit 3 and prevent it from being washed away by the water flow, anchor nails are provided on the bottom surface of the channel body 21, which can be directly inserted into the soil for fixation.

[0025] In a preferred embodiment, the socket-type drainage ditch 2 is made entirely of high-strength engineering plastic, which makes it not only lightweight and corrosion-resistant, but also relatively low in production cost, and has great potential for widespread application.

[0026] During operation, the accumulated water in the foundation pit 3 first flows into the socket-type drainage ditch 2. Some of the sand and gravel in the water flow is intercepted by the filter baffle 22, and then the water flow is guided to the collection well. The water flow containing a small amount of fine sand enters the interior of the support part 1 through the drainage holes 14 on the top plate 12 and side plate 11, while most of the sand and gravel is blocked outside. Finally, the water that has entered the interior of the support part 1 is relatively clean and can be safely and efficiently pumped out by the water pump, thus completing the entire drainage and protection process.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
