The water storage tank wall 4 can be a reinforced concrete tank with water storage function or a silica sand water storage tank wall 4 with purification function.
In one possible implementation, referring to fig. 1 and 2, the prefabricated ventilation and anti-seepage structure 5 provided in the embodiment of the present invention includes an anti-seepage column 51, one end of the anti-seepage column 51 is disposed on one side of the ventilation supporting layer 2 near the bearing layer 3, the other end of the anti-seepage column 51 penetrates through the bearing layer 3, and the other end surface of the anti-seepage column 51 is higher than or flush with the top surface of the bearing layer 3. The structure of the barrier column 51 may be a rectangular parallelepiped or a prismatic structure, etc., in one example, the barrier column 51 is a cylindrical structure, the diameter of the cylindrical barrier column 51 may be 20 cm-50 cm, for example, the diameter of the cylindrical barrier column 51 may be 20cm, 24 cm, 28 cm, 30 cm, 35 cm, 40cm, 45 cm, 50cm, etc., the height of the barrier column 51 may be 10 cm-50 cm, for example, the height of the barrier column 51 may be 10cm, 20cm, 25cm, 30 cm, 35 cm, 40cm, 45 cm, 50cm, etc., although this is merely illustrative and not limiting. The height of the impermeable column 51 is the dimension of the impermeable column 51 in the direction from the foundation layer 1 to the bearing layer 3.
In one possible implementation, the number of the seepage-proofing columns 51 is plural, and the plurality of seepage-proofing columns 51 are stacked in order from the base layer 1 to the bearing layer 3. Thus, the number of the anti-seepage columns 51 can be determined according to the vertical distance between the actual support plate 52 and the accommodating space, the phenomenon that the anti-seepage columns 51 are wasted due to insufficient height and size of the single anti-seepage column 51 and cannot be used is avoided, and meanwhile, the prefabricated ventilation anti-seepage structure 5 is ensured to be capable of communicating the accommodating space with the ventilation support layer 2 to form a ventilation channel. In particular embodiments, the number of barrier columns 51 may be two, three, four or more, and is not particularly limited herein. The two adjacent seepage-proofing columns 51 can be adhered and fixed, so that the integrity and the structural strength of the prefabricated ventilation seepage-proofing structure 5 are improved, and meanwhile, the phenomenon of water seepage between the two adjacent seepage-proofing columns 51 is avoided.
As an example, the cross-section of the barrier column 51 located near the base layer 1 is larger than the cross-section of the barrier column 51 located far from the base layer 1. So, when there is the groundwater phenomenon, be located the one side part that keeps away from base layer 1 that is close to the prevention of seepage post 51 of base layer 1 and be connected with spandrel layer 3, spandrel layer 3 has decurrent effort to prevention of seepage post 51, can be effectively with the fixed position of prefabricated ventilative prevention of seepage structure 5, avoid prefabricated ventilative prevention of seepage structure 5 to appear the slope phenomenon. Specifically, the cross section of the barrier column 51 located near the base layer 1 is 10cm and more larger than the diameter of the cross section of the barrier column 51 located far from the base layer 1 adjacent thereto, as the case may be.
In one possible implementation, the barrier column 51 includes particulates, a surface modifier that alters the surface tension of the particulates, and an organic solution that facilitates enhancing the hydrophobic effect of the barrier column 51. Wherein the weight ratio of particulate matter to surface modifier is 4:4-4:2, illustratively, the weight ratio of particulate matter to surface modifier may be 4:4, 4:3.8, 4:3.4, 4:3.2, 4:3, 4:2.5, 4:2.2, 4:2, etc. The weight ratio of the surface modifier to the organic solution is 1:1 to 1:10, and illustratively, the weight ratio of the surface modifier to the organic solution may be 1:2, 1:2.5, 1:3, 1:4, 1:5, 1:7.5, 1:8, 1:10, etc., although the practice is not limited thereto.
In one example, the particulates include 100 mesh-200 mesh sand and 70 mesh-140 mesh diatomite particles, the sand may be river sand, machine-made sand, desert sand, or the like, the mesh number of the sand may be 100 mesh, 120 mesh, 150 mesh, 180 mesh, 200 mesh, or the like, the mesh number of the diatomite particles may be 70 mesh, 80 mesh, 100 mesh, 120 mesh, 140 mesh, or the like, and the weight ratio of the sand to the diatomite particles may be 1:2-1:4, and illustratively, the weight ratio of the sand to the diatomite particles may be 1:2, 1:2.5, 1:2.8, 1:3, 1:3.6, 1:4, or the like.
In another example, the surface modifying agent includes Polydimethylsiloxane (PDMS) and gamma-methacryloxypropyl trimethoxysilane (KH-570) that help to alter the surface tension of the particulate matter and enhance the hydrophobic effect of the barrier column 51. The weight ratio of polydimethylsiloxane to gamma-methacryloxypropyl trimethoxysilane is 1:3-2:1, and illustratively, the weight ratio of polydimethylsiloxane to gamma-methacryloxypropyl trimethoxysilane can be 1:3, 1:2.5, 1:2, 1:1.5, 1:1, 2:1, etc., as exemplified herein, particularly in practice.
In some embodiments, the barrier column 51 further includes a dimethyl ether-silicone resin (Me-MQ) to enhance the structural strength of the barrier column 51. Wherein the weight ratio of the particulate matter to the dimethyl ether-silicone resin is 4:4-4:3, specifically, the weight ratio of the particulate matter to the dimethyl ether-silicone resin may be 4:3.8, 4:3.6, 4:3.5, 4:3.2, 4:3, etc.
In specific implementation, 30-60 parts by weight of sand with 100-200 meshes, 10-20 parts by weight of diatomite particles with 40-70 meshes, 20-40 parts by weight of polydimethylsiloxane, 20-40 parts by weight of gamma-methacryloxypropyl trimethoxy silane, 40-80 parts by weight of dimethyl ether-organic silicon resin and organic matters can be selected for consolidation molding at normal temperature. The weight ratio of particulate matter, polydimethylsiloxane, gamma-methacryloxypropyl trimethoxysilane, and dimethyl ether-silicone resin may be 4:1:3:3, 4:2:1:4, without specific limitation herein. Through a plurality of experiments, when the weight ratio of the particulate matters to the polydimethylsiloxane to the gamma-methacryloxypropyl trimethoxysilane to the dimethyl ether-silicone resin is 4:2:2:4, the anti-seepage column 51 has the best hydrophobic performance, the highest mechanical strength and the best air permeability.
In one possible implementation, the organic solution includes at least one of ethyl acetate or toluene, and the organic solution may be ethyl acetate, toluene, or a mixed solution of ethyl acetate and toluene.

The backup pad 52 is used for supporting the prevention of seepage post 51, and the uneven subsidence of ventilative supporting layer 2 or spandrel layer 3 can be avoided in the setting of backup pad 52, and then the prevention of seepage post 51 that leads to tears, appears the phenomenon of infiltration. In particular, the supporting plate 52 may be a concrete slab, the thickness of the supporting plate 52 may be 10 cm-20 cm, illustratively, the thickness of the supporting plate 52 may be 10cm, 12 cm, 14 cm, 15 cm, 18 cm, 20cm, etc., the supporting plate 52 may be permeable concrete, optionally graded crushed stone, and the porosity of the crushed stone may be 15% -30%, illustratively, the porosity of the crushed stone may be 15%, 18%, 20%, 25%, 28%, 30%, etc., which is not limited herein.
