Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to an easily cleanable retractable bamboo-joint water-draining and pressure-reducing system. Background Art

[0002] At present, some new or existing building basements solve the anti-floating problem by installing a water discharge and pressure relief system.

[0003] The anti-floating and decompression system is achieved by drilling holes in the basement floor of the building, burying filter pipes, opening grooves in the floor, laying drainage pipes to the sump, connecting the filter pipes to the drainage pipes, and finally sealing the holes and grooves in the floor.

[0004] The groundwater seeping from the foundation soil at the bottom of the foundation and the gap water between the bottom plate and the foundation soil are filtered through the filter pipe and discharged into the sump through the drainage pipe, and then pumped out of the basement by the submersible pump installed in the sump.

[0005] The groundwater seeping out of the soil and the interstitial water between the bottom plate and the foundation soil will carry sand particles, which will gradually deposit on the outer wall of the filter tube when filtered through the filter tube to form a mud film, reducing the water output of the filter tube. Eventually, it may even cause the filter tube to be completely blocked, unable to discharge water, and the water discharge and pressure reduction system to fail.

[0006] At present, filter bags or filter tubes are usually used as groundwater filtration devices. The filter bag has a short lifespan. Once it is clogged with fine particles of sand, the entire water discharge and pressure relief system will fail and cannot be replaced, which has serious defects. The filter tube can be cleaned, usually by using a high-pressure water gun to spray and flush from the inside to the outside of the filter tube. According to feedback from actual projects, this method is not very ideal for four reasons: 1. Flushing from the inside to the outside through the filter screen or wire wrapping, if the flushing pressure is too high, it is easy to damage the filter screen or wire wrapping, resulting in failure of the filter tube; 2. Manual flushing is uneven, and some locations are not cleaned; 3. The sewage cannot be discharged quickly after flushing. After standing for a period of time, the sand particles will settle again and block the filter tube; 4. High-pressure water jet flushing, excessive water pressure will disturb the foundation soil at the bottom of the bottom plate. In severe cases, it may cause soil erosion in some areas to form cavities, or loose soil, resulting in reduced foundation bearing capacity or uneven settlement, affecting the safety of the building structure.

[0007] In summary, there is a need for a filter tube with a completely new structure, which has the characteristics of easy cleaning of the outside of the filter tube, more lasting cleaning effect, no disturbance of the surrounding soil, and long service life. Summary of the invention

[0010] Preferably, the filter material layer comprises, from outside to inside, a fine particle filter material layer and a coarse particle filter material layer.

[0011] Preferably, the bamboo-section wire-wrapped filter further comprises a filter top cover, which is connected to the top of the filter upper tube section; a drain outlet is formed on the top of the filter top cover; the drain outlet is connected to the drain pipe via a U-shaped tube with a connector.

[0012] Preferably, it also includes a stainless steel sealing ring, which is arranged on the outer edge of the upper part of the filter upper pipe section and located between the filter upper pipe section and the stainless steel sleeve; a sealing rubber ring is respectively arranged on the inner and outer sides of the stainless steel sealing ring.

[0013] Preferably, the top of the sewage pipe is connected to a plug or a water pump, and the water outlet of the water pump is connected to the sump or drainage ditch.

[0016] 1. Through the cooperation of the filter upper tube section, filter lower tube section, stainless steel sleeve and brush, a retractable bamboo-shaped structure is formed. Clean water is injected into the inside of the filter element. The filter upper tube section and filter lower tube section are pulled up and down. The outer wall of the filter tube can be scrubbed with a brush without the need to use a high-pressure water gun for spraying and flushing. The sewage containing mud and sand particles after scrubbing exists in the inner cavity of the wire mesh column. The sewage pipe is connected to a pump to extract the sewage containing soil particles in the cavity to complete a cleaning cycle. It can be circulated many times until the water discharged from the sewage pipe is clean water, which means that the outside of the filter element and the cavity have been cleaned.

[0017] Second, the filter material layer includes a fine particle filter material layer and a coarse particle filter material layer from the outside to the inside, and adopts a double-layer filler structure. The fine particle filler is directly in contact with the outer soil, and the inner filler is a coarse particle filler with a larger particle size. A wire mesh column with a certain strength is set inside the coarse particle filler to separate the coarse particle filter material, forming an inner cavity. The inner cavity provides space for the brushing operation of the bamboo-shaped filter element.

[0018] The present invention can effectively clean the outer wall of the filter element of the water drainage and pressure relief system buried in the soil; the operation is simple and the cleaning effect is good; there is no need to use a high-pressure water gun for flushing, thereby avoiding disturbance of the foundation soil; the structure is simple and the manufacturing cost is low.
