Description

Technical Field

[0001] This application relates to the field of foundation pit drainage technology, specifically a water collection sleeve for water supply and drainage in deep foundation pits. Background Technology

[0002] A foundation pit is defined as a pit with a bottom area of ​​less than 27 square meters and a bottom longer side less than three times the shorter side. A foundation trench is defined as a trench with a bottom width of less than 3 meters and a trench length greater than three times the trench width. A deep foundation pit is defined as a pit with a bottom area of ​​less than 27 square meters and a bottom longer side less than three times the shorter side, with an excavation depth exceeding 5 meters (including 5 meters) or having three or more basement levels (including three levels), or a project with particularly complex geological conditions, surrounding environment, and underground pipelines even if the depth does not exceed 5 meters. Conversely, a shallow foundation pit is defined as a pit with less than 27 square meters of bottom area and a bottom longer side less than three times the shorter side. Foundation pit drainage is a very important part of construction organization, but it is often overlooked. In many projects, due to inadequate consideration of the seepage prevention treatment of the cofferdam and foundation, drainage costs are significantly increased and foundation pits are flooded, delaying the construction period.

[0003] In existing open drainage systems for foundation pits, a filter screen is needed to filter silt and sand when water is discharged into the casing through the drainage pipe to prevent the submersible pump from clogging. However, most of the filter screens are fixed inside the casing, and long-term use can cause silt and sand to clog the filter screen, thereby reducing the drainage effect and the water collection efficiency. Therefore, a water collection casing for deep foundation pit water supply and drainage is needed. Utility Model Content

Detailed Implementation

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1 and Figure 2This application provides a water collection sleeve for water supply and drainage in deep foundation pits, including a sleeve 1 and an mounting block 2. A water collection groove 101 is formed inside the sleeve 1, and symmetrical sliding grooves 102 are formed on the inner wall of the water collection groove 101. Sliding blocks 201 adapted to the sliding grooves 102 are symmetrically fixedly connected to the outer side of the mounting block 2. The mounting block 2 is slidably connected to the sliding grooves 102 inside the water collection groove 101 via the sliding blocks 201. A connecting column 202 is fixedly connected to the lower surface of the mounting block 2, and a sediment filter plate 203 is fixedly connected to the lower surface of the connecting column 202. The sediment filter plate 203 is connected to the water collection groove 101 via the sliding blocks 201. The water collection tank 101 is slidably connected. When the sediment filter plate 203 becomes clogged after long-term use and needs to be cleaned, the slider 201 can be moved out of the slide groove 102 by moving the slider 201 within the slide groove 102. This causes the sediment filter plate 203 to move upward and out of the water collection tank 101, making it easier to clean the surface of the sediment filter plate 203. After cleaning, the slider 201 is placed in the slide groove 102 and slid downward to its original position. This allows for quick cleaning and installation of the sediment filter plate 203, preventing sediment from clogging the sediment filter plate 203 and reducing its drainage effect.

[0031] Reference Figure 1 and Figure 3 In one aspect of this embodiment, a weight block 211 is fixedly connected to the lower surface of the sediment filter plate 203. The weight block 211 accelerates the sinking of the sediment filter plate 203 and increases the stability of the sediment filter plate 203 in use.

[0032] Reference Figure 1 and Figure 2 In one aspect of this embodiment, a submersible pump 3 is fixedly installed on the upper surface of the mounting block 2, and the submersible pump 3 is used to pump out the water in the water collection tank 101.

[0033] Reference Figure 1 and Figure 2 In one aspect of this embodiment, a fixing ring 4 is slidably connected to the outer side of the sleeve 1. A plurality of fixing blocks 401 are uniformly and symmetrically fixed to the outer side of the fixing ring 4. Fixing nails 402 are fixedly connected to the lower surface of each fixing block 401. Fixing components 5 for fixing the fixing ring 4 to the sleeve 1 are symmetrically arranged on the outer side of the fixing ring 4. By moving the fixing ring 4 downward on the outer side of the sleeve 1, the lower surface of the fixing nails 402 is inserted into the ground. Then, the fixing components 5 fix the fixing ring 4 to the sleeve 1, thereby increasing the stability of the sleeve 1 in use.

[0034] Reference Figure 1 , Figure 2 and Figure 4In one aspect of this embodiment, the fixing component 5 includes a fixing bolt 501, a first threaded hole 502 symmetrically opened on the outer side of the fixing ring 4, and a second threaded hole 503 corresponding to the first threaded hole 502 symmetrically opened on the outer side of the sleeve 1. One end of the fixing bolt 501 is threadedly connected to the first threaded hole 502 inside the first threaded hole 502. By rotating the fixing bolt 501, one end of the fixing bolt 501 passes through the first threaded hole 502 to the inside of the second threaded hole 503, thereby fixing the fixing ring 4 to the sleeve 1.

[0035] Reference Figure 1 and Figure 2 In one aspect of this embodiment, a water inlet pipe 6 is fixedly connected to the lower outer side of the sleeve 1. The water inlet pipe 6 communicates with the internal water collection tank 101 of the sleeve 1, and water is discharged into the water collection tank 101 through the water inlet pipe 6.

[0036] All electrical devices in this plan are powered by an external power source.

[0037] Working principle: During use, water is discharged into the water collection tank 101 through the water inlet pipe 6, and the water in the water collection tank 101 is pumped out by the submersible pump 3. When the sediment filter plate 203 becomes clogged after long-term use and needs to be cleaned, the slider 201 can be moved out of the slide groove 102 by moving it within the slide groove 102. This causes the sediment filter plate 203 to move upwards and out of the water collection tank 101, making it easier to clean the surface of the sediment filter plate 203. After cleaning, the slider 201 is placed back into the slide groove 102. Sliding down to its original position allows for quick cleaning and installation of the sediment filter plate 203, preventing sediment from clogging the filter plate 203 and reducing drainage efficiency. The weight block 211 accelerates the sinking of the sediment filter plate 203, increasing its stability. The fixing ring 4 moves downward on the outside of the sleeve 1, causing the lower surface of the fixing nail 402 to insert into the ground. By rotating the fixing bolt 501, one end of the fixing bolt 501 passes through the first threaded hole 502 to the inside of the second threaded hole 503, thus fixing the fixing ring 4 to the sleeve 1.
