Description

Technical Field

[0001] The utility model relates to the technical field of seepage water intake, in particular to a prefabricated seepage water intake segment and a segmented beach seepage water intake system. Background Art

[0002] At present, with the development of the national economy, all walks of life have a greater demand for water resources, and it is necessary to expand water intake locations and achieve water diversification.

[0003] Therefore, the water extraction method is no longer limited to the traditional method of diverting water from natural rivers, but also includes infiltration water extraction from areas rich in water such as beaches.

[0004] There are two ways to divert water from natural rivers: 1. Build a canal head and divert river water directly. However, this method not only requires a large investment in water diversion projects, but also makes it difficult to guarantee water quality. 2. Set up a water intake device in the natural river to divert river water to the shore. If conditions permit, gravity will be used. If conditions do not permit, water will be pumped to where it is needed. This type of water intake device usually uses a tower water intake device and a mushroom head water intake device. However, since the water intake device is higher than the riverbed, it is easy to collide with navigable ships, which will not only cause damage to the ships and water intake device, but also affect navigation.

[0005] Infiltration water extraction in water-rich land such as beaches is to bury infiltration pipes in water-rich land such as beaches to extract water through infiltration. This method largely makes up for the shortcomings of the above-mentioned method of diverting natural river water.

[0006] However, when the infiltration pipe is used to extract water through infiltration, the beach and other places will crack and collapse due to the reduction of water, resulting in the infiltration pipe being exposed.

[0007] At the same time, the water quality obtained through the infiltration pipe alone is still poor and cannot meet the increasing water quality demand. Utility Model Content

[0008] The purpose of the utility model is to provide a prefabricated seepage water intake segment and a segmented beach seepage water intake system, which can be used to extract groundwater on the beach, improve the water quality, reduce construction difficulty, and improve construction efficiency.

[0009] A prefabricated seepage water intake segment comprises a transversely arranged composite resin concrete bin, which is a strip frame with openings at both ends and a rectangular cross-section. An array of water holes is provided on the top and side walls of the composite resin concrete bin.

[0010] A stainless steel mesh cage set is arranged on the bottom of the composite resin concrete silo. Both ends of the stainless steel mesh cage set are open and the length is consistent with that of the composite resin concrete silo.

[0011] A tubular filter water collector is fixed in the stainless steel mesh cage set combination. Both ends of the tubular filter water collector are open, and the length is consistent with the composite resin concrete bin.

[0012] The stainless steel mesh cage set assembled outside the tubular filter water collector can filter and remove the infiltrated groundwater, thereby improving the water quality. At the same time, the stainless steel mesh cage set and the composite resin concrete silo can also protect the tubular filter water collector, thereby extending the service life of the tubular filter water collector.

[0013] The above structure is simple, can be prefabricated in a modular manner, and has a simple assembly method, thereby reducing construction difficulty and improving construction efficiency. In addition, prefabrication of finished products can replace manual labor with machines, effectively reducing labor costs.

[0014] Furthermore, the stainless steel mesh cage set combination is provided with at least one layer of stainless steel mesh cages, and the apertures of all stainless steel mesh cages gradually increase from the outside to the inside. The aperture of the stainless steel mesh cage away from the tubular filter water collector is the smallest, and the aperture of the stainless steel mesh cage close to the tubular filter water collector is the largest.

[0015] Furthermore, filter materials are filled between the tubular filter water collector and the stainless steel mesh cage, between the stainless steel mesh cages, and between the stainless steel mesh cages and the composite resin concrete bin;

[0016] The diameter of the filter material increases gradually from the outside to the inside, the diameter of the filter material far away from the tubular filter water collector is the smallest, and the diameter of the filter material close to the tubular filter water collector is the largest.

[0017] Furthermore, the pore size of the stainless steel mesh cage is smaller than the minimum diameter of the filter material.

[0018] The filter material is wrapped in a composite resin concrete silo and a stainless steel mesh cage. The infiltrated groundwater will pass through various levels of filter material and reach the filter collector, where it will be finally filtered and collected. After the groundwater is filtered multiple times through the filter material, the mud residue in the water is significantly reduced, and the water quality of the taken groundwater is greatly improved.

[0019] Furthermore, a filter stone combination is arranged on the outer wall of the composite resin concrete bin.

[0020] Furthermore, the filter stone combination is provided with at least one filter stone, and the filter stone is arranged around the top wall and side walls of the composite resin concrete bin;

[0021] The diameter of the filter stone increases gradually from bottom to top, the diameter of the filter stone far away from the top wall of the composite resin concrete bin is the smallest, and the diameter of the filter stone close to the top wall of the composite resin concrete bin is the largest.

[0022] Furthermore, the tubular filter water collector is a percolation tube.

[0023] A segmented beach seepage water intake system, the key of which is that it is composed of at least two prefabricated seepage water intake segments spliced ​​in sequence;

[0024] Among them, the composite resin concrete silos are connected by socket and external sealing cement;

[0025] The stainless steel mesh cages are directly spliced ​​through the module ends;

[0026] The tubular filter water collectors are connected by sockets and spigots.

[0027] The factory prefabricates the seepage water intake segments. At the construction site, it is only necessary to assemble and splice multiple sections of the seepage water intake segments to form a seepage water intake system. This not only reduces the construction difficulty and improves the construction efficiency, but also reduces manpower and maintenance costs.

[0028] Beneficial effects: 1. The utility model reduces construction difficulty and improves construction efficiency through prefabrication and assembly.

[0029] 2. The filter materials of different particle sizes in the device of the utility model can filter groundwater multiple times, thereby improving the water quality. At the same time, it can effectively prevent blockage, realize rapid filtration and smooth transportation of water flow, ensure stable operation of the system, and reduce manpower and maintenance costs.

[0030] 3. The stainless steel mesh cage set combination and the composite resin concrete silo can also protect the tubular filter water collector, preventing the beach from cracking and collapsing, and exposing the tubular filter water collector, thereby extending the service life of the tubular filter water collector.

[0036] The specific implementation manner and working principle of the present invention are further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1-4 As shown, a prefabricated seepage water intake segment includes a transversely arranged composite resin concrete bin 3, which is a strip frame with openings at both ends and a rectangular frame cross section;

[0038] A stainless steel mesh cage set is arranged on the bottom of the composite resin concrete bin 3. The two ends of the stainless steel mesh cage set are open and the length is consistent with the composite resin concrete bin 3.

[0039] A tubular filter water collector 1 is fixed in the stainless steel mesh cage set assembly. The tubular filter water collector 1 is a percolation pipe with openings at both ends. The length of the percolation pipe is consistent with the composite resin concrete bin 3.

[0040] The length of the tubular filter water collector 1, the stainless steel mesh cage set combination and the composite resin concrete silo 3 are all 2m.

[0041] like Figure 1 、 Figure 2 As shown, the stainless steel mesh cage set combination is provided with two layers of stainless steel mesh cages 2 with different apertures. The apertures of the two layers of stainless steel mesh cages 2 gradually increase from the outside to the inside. The aperture of the stainless steel mesh cage 2 away from the tubular filter water collector 1 is the smallest, and the aperture of the stainless steel mesh cage 2 close to the tubular filter water collector 1 is the largest.

[0042] like Figure 1 As shown, filter materials 4 of different particle sizes are filled between the composite resin concrete bin 3 and the outer stainless steel mesh cage 2, between the outer stainless steel mesh cage 2 and the inner stainless steel mesh cage 2, and between the inner stainless steel mesh cage 2 and the tubular filter water collector 1.

[0043] The diameters of all filter materials 4 gradually increase from the outside to the inside, with the filter materials 4 farther away from the tubular filter water collector 1 having the smallest diameter and the filter materials 4 closer to the tubular filter water collector 1 having the largest diameter;

[0044] The composite resin concrete silo 3 and the outer stainless steel mesh cage 2 are filled with filter material 4 with a diameter of 1 to 4 mm; the outer stainless steel mesh cage 2 and the inner stainless steel mesh cage 2 are filled with filter material 4 with a diameter of 4 to 8 mm; and the inner stainless steel mesh cage 2 and the tubular filter water collector 1 are both filled with filter material 4 with a diameter of 8 to 22 mm.

[0045] like Figure 1 As shown, the pore size of the two layers of stainless steel mesh cages 2 is smaller than the minimum diameter of the filter material 4, so the pore size of the two layers of stainless steel mesh cages 2 is less than 1 mm.

[0046] like Figure 3 、 Figure 4 As shown, the top wall and the side wall of the composite resin concrete bin 3 are provided with a water passing hole array, and the water passing hole array on the side wall is provided with 5*3 water passing holes 31, and the water passing hole array on the top wall is provided with 5*5 water passing holes 31.

[0047] As shown, Figure 1 As shown, the outer wall of the composite resin concrete bin 3 is arranged with a filter stone combination, which is provided with two filter stones 2 with different diameters, and the filter stones 2 are arranged around the top wall and the side wall of the composite resin concrete bin 3.

[0048] The diameters of the filter stones 2 gradually increase from bottom to top, and the diameter of the filter stone 2 farthest from the top wall of the composite resin concrete bin 3 is the smallest, and the diameter of the filter stone 2 closest to the top wall of the composite resin concrete bin 3 is the largest.

[0049] As shown, Figure 5 As shown, a segmented beach seepage water taking system is composed of three precast seepage water taking segments connected in sequence, wherein the composite resin concrete bins 3 are connected by socketed outer sealing cement, the stainless steel mesh cages 2 are directly connected by module ends, and the tubular filter water collectors 1 are connected by sockets.

[0050] When installing the segmented beach seepage water taking system, the construction personnel need to dig a segmented beach seepage water taking system installation groove on the beach, then splice the precast multiple seepage water taking segments, and fill filter material 4 with a diameter of 1-4mm between the composite resin concrete bin 3 and the outer stainless steel mesh cage 2; fill filter material 4 with a diameter of 4-8mm between the outer stainless steel mesh cage 2 and the inner stainless steel mesh cage 2; and fill filter material 4 with a diameter of 8-22mm between the inner stainless steel mesh cage 2 and the tubular filter water collector 1.

[0051] After the filter material 4 is filled, two filter stones 2 with different diameters are arranged outside the top wall and the side wall of the composite resin concrete bin 3, and the diameters of the filter stones 2 gradually increase from bottom to top, and the diameter of the filter stone 2 farthest from the top wall of the composite resin concrete bin 3 is the smallest, and the diameter of the filter stone 2 closest to the top wall of the composite resin concrete bin 3 is the largest.

[0052] Finally, the segmented beach seepage water taking system installation is completed by backfilling the seepage water taking system installation groove with original sand.
