Description

Technical Field

[0001] The present invention relates to the technical field of blind ditch pipes for blind ditch drainage, and specifically to a blind ditch pipe for underground filter layer decompression combined with blind ditch drainage. Background Art

[0002] With the rapid development of cities, urban land is becoming increasingly scarce, and the development and utilization of underground space are becoming more and more important. Underground buildings have become an indispensable part of many buildings. Chongqing, known as the "mountain city", has undulating terrain and large topographic height differences. Its foundation is often dominated by high-strength rocks and rock-soil mixed structures, with crisscrossing fissures, making the flow state of groundwater relatively complex and the flow area changing greatly. As a result, during geological exploration, it is impossible to accurately detect the shape of groundwater, leading to the lack of structural anti-floating floor design in the design of many underground buildings. During construction, the disturbance of the ground base may cause changes in groundwater runoff. During the rainy season, the groundwater runoff will cause the water level to rise, even higher than the elevation of the underground building floor slab, quickly forming hydrostatic pressure, damaging the building floor slab, and resulting in phenomena such as water seepage and gushing water, causing indoor humidity, ground waterlogging, and even other uncontrollable quality and safety hazards. By scientifically applying filter layer decompression and blind ditch drainage techniques, based on the groundwater pressure, the collection and drainage of water can be reasonably realized, facilitating timely corresponding arrangements at appropriate times, and demonstrating the advantages of green construction, safety, reliability, durability, and environmental protection. By using finished plastic blind ditch pipes and combining with relatively advanced and professional technical means, the process of blind ditch drainage can be made smoother, thus meeting the basement anti-floating design standards. Filter layer decompression and blind ditch drainage enhance the durability of the building beyond its service life, ensuring that the corresponding building can reasonably exert its practical value.

[0003] In the prior art, blind ditch drainage usually uses blind ditch pipes for drainage. Blind ditch pipes generally adopt porous materials or welded mesh structures to provide good permeability. Common structural forms include solid-core circular, circular ring, circular inner support, and rectangular, etc.

[0004] However, in the existing prior art, there are some deficiencies in the actual application of blind drain pipes. On the one hand, its compressive performance needs to be improved. In some complex geological conditions or high-load environments, blind drain pipes are prone to deformation or damage due to large pressures, thus affecting their drainage function and service life. For example, in landfills, as the landfill body settles, the upper layer of garbage exerts a large pressure on the lower layer of pipes, easily causing the pipe joints to break, resulting in the accumulation of leachate and the inability of biogas to escape, posing safety hazards. On the other hand, the connection method of blind drain pipes is relatively cumbersome. Traditional connection methods usually require a large number of connectors and tools, with complex operations and time-consuming and laborious processes. For example, some blind drain pipes need to be connected by welding, threaded connection, or nesting. These methods not only require professional technicians and equipment but are also prone to errors during the connection process, affecting the tightness and stability of the connection. Summary of the Invention

[0005] The purpose of the present invention is to provide a blind drain pipe for underground water filtration layer decompression combined with blind drain, so as to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: a blind drain pipe body, with four groups of card slots opened around the inner wall of the blind drain pipe body. A support frame is held in the card slots, and multiple support rings are connected to the inner side of the support frame; a connection slot is opened at one end of the support frame, and a connection plug is connected to the other end of the support frame. Fixing slots are opened at the upper and lower ends in the middle of the connection slot, and first telescopic slots are opened at the upper and lower ends in the middle of the connection plug. Fixing blocks are elastically connected in the first telescopic slots.

[0007] Preferably, a connection slot is opened at one end of the blind drain pipe body, and a connection plug ring is provided at the other end. The connection plug ring of another blind drain pipe body can be inserted into the connection slot opened at one end of the blind drain pipe body to connect the two blind drain pipe bodies.

[0008] Preferably, multiple support rings are welded around the inner side of the support frame, and a rigid cross support is welded on the inner side of the support ring. The support frame, support ring, and cross support form a support assembly to stably support the blind drain pipe body.

[0009] Preferably, multiple through holes are opened around the connection plug ring. The connection plug provided at one end of the support frame passes through the through holes opened around the connection plug ring, and the distance from the protruding connection plug to the outer surface of the connection plug ring is the same as the depth of the connection slot.

[0010] Preferably, first telescopic slots are opened at the upper and lower ends in the middle of the connection plug. First springs are arranged in the first telescopic slots. One end of each first spring is connected to the inner wall of the first telescopic slot, and the other end of each first spring is connected to a fixing block. The fixing block can expand and contract according to the elastic force of the first spring.

[0011] Preferably, the connecting block is provided with a second telescopic slot at the top end of the first telescopic slot, a second spring is arranged in the second telescopic slot, one end of the second spring is connected to the inner wall of the second telescopic slot, and the other end of the second telescopic slot is connected to the closing plate, and the closing plate can close the first telescopic slot to clamp the fixed block into the first telescopic slot.

[0012] Preferably, the upper and lower ends of the connecting plug are provided with sliding grooves, the sliding grooves are located in the middle of the upper and lower surfaces of the connecting plug, and the bottom of the sliding grooves is parallel to the bottom of the second telescopic groove.

[0013] Preferably, when the two groups of blind ditch pipe bodies are connected, the connecting plug can be plugged into a connecting slot provided at one end of the inner support frame of the other group of blind ditch pipe bodies to connect the two groups of support frames.

[0014] Preferably, the connecting slot is provided with a toggle block at the front end of the fixed slot. When another set of connecting blocks is plugged into the connecting slot, the toggle block is plugged into the sliding grooves opened at the upper and lower ends of the connecting blocks. As the connecting blocks go deeper, the toggle block can squeeze the closing plate, causing the closing plate to shrink into the second telescopic slot, thereby opening the closure of the first telescopic slot.
