[0037] Example 1:
[0038] This embodiment provides a garage waterproof floor, such as Figure 1 As shown, it includes a porous low-shrinkage concrete layer 6 and a UHPC inorganic grindstone layer 7 arranged in sequence from the bottom to the surface; the UHPC inorganic grindstone layer 7 is embedded with a tensile crack-resistant grid mesh; the grid mesh is made of a high molecular polymer material;
[0039] The meshes of the grille net include square holes with a side length of 3 cm to 7 cm and / or square holes with a side length of 8 cm to 11 cm.
[0040] During construction, you can choose a grid mesh with square holes of 5cm or 10cm in length.
[0041] The UHPC inorganic grindstone layer 7 is arranged on the surface to directly bear the vehicles and resist the impact load. UHPC is an ultra-high performance concrete with high strength, high durability and excellent wear resistance. A porous low-shrinkage concrete layer 6 is laid under the UHPC inorganic grindstone layer 7. Due to the porous characteristics of the porous low-shrinkage concrete layer 6 itself, in addition to providing support, it can also quickly and conveniently drain the water that seeps from the drainage trough through the porous low-shrinkage concrete layer. Therefore, the accumulated water will not accumulate in the UHPC inorganic grindstone layer 7 for a long time, thereby increasing the infiltration rate of water in the UHPC inorganic grindstone layer and facilitating the rapid absorption of accumulated water on the floor surface.
[0042] First, the interconnected pores of the porous low-shrinkage concrete layer 6 can effectively drain water and prevent moisture from returning to the floor surface. Second, the porous structure can improve the interfacial adhesion with the UHPC inorganic grindstone layer 7, thereby increasing the pull-out strength between the two and preventing hollowing of the UHPC inorganic grindstone layer 7 on the surface. Third, the low-shrinkage concrete used in the porous low-shrinkage concrete layer 6 can prevent excessive shrinkage and expansion of the base layer, which may cause cracking of the floor.
[0043] A grid mesh is introduced into the UHPC inorganic grindstone layer 7 to prevent the floor surface from cracking. At the same time, different pigments, aggregates, decorative strips, etc. can be selected according to predetermined patterns and colors to achieve visual beautification and information identification of the floor.
[0044] In this embodiment, the grinding stone material of the UHPC inorganic grinding stone layer includes one or more of limestone particles, granite particles, marble particles, artificial stone particles, quartz particles, alloy particles, washed stone, pebbles and the like.
[0045] In this embodiment, the thickness of the UHPC inorganic grinding stone layer ranges from 10 mm to 30 mm; and the upper surface of the UHPC inorganic grinding stone layer is polished to form a smooth structure.
[0046] The construction process parameter requirements of UHPC inorganic grinding stone layer are shown in Table 1 and Table 2.
[0047] Table 1: UHPC inorganic grinding stone layer construction process parameters
[0048] content parameter thickness 1cm-3cm Flexural strength 10.5Mpa-15Mpa
[0049] The porous low-shrinkage concrete layer includes a porosity range of 5%-10% or 10%-15%. The thickness of the porous low-shrinkage concrete layer 6 is 40mm-200mm, and the porous low-shrinkage concrete layer 6 is provided with a grid mesh or wire mesh made of a polymer. The water permeability of the porous low-shrinkage concrete layer 6 is greater than or equal to 1mm / s. Porosity of 5%-10% is more suitable for garage driveways, where the strength of the porous low-shrinkage concrete layer 6 must be greater than or equal to 30 MPa. Porosity of 10%-15% is more suitable for garage parking areas, where the strength of the porous low-shrinkage concrete layer 6 must be greater than or equal to 25 MPa.
[0050] The construction process parameters of porous low shrinkage concrete layer are as follows:
[0051] Table 2 Construction process parameters of porous shrinkage concrete layer
[0052] area strength Porosity thickness Permeability coefficient Polymer Grid driving lane ≥30mpa 5％-10％ 4-20cm ≥1mm / s Aperture 5-15cm parking area ≥25mpa 10％-15％ 4-20cm ≥1mm / s none
[0053] The surface of the UHPC inorganic grinding stone layer 7 is provided with a number of dot-shaped pits and / or strip-shaped water-conducting grooves. By creating these dot-shaped pits and / or strip-shaped water-conducting grooves on the surface of the UHPC inorganic grinding stone layer 7, the friction between the vehicle and the UHPC inorganic grinding stone layer 7 is artificially increased, preventing the vehicle from slipping.
[0054] like Figure 3 and Figure 4 As shown, it also includes a drainage trough 8, which is embedded in the garage waterproof floor and separates the UHPC inorganic grindstone layer 7 and the porous low-shrinkage concrete layer 6. The bottom of the drainage trough 8 is in contact with the waterproof layer 5, and a drainage hole 81 is provided on one side of the drainage trough 8.
[0055] When the garage is on a sloped road surface, the drainage trough 8 is provided with a drainage hole 81 on one side facing the top of the slope. The water in the porous low-shrinkage concrete layer 6 and the UHPC inorganic grinding stone layer 7 on the upper section of the slope is drained into the drainage trough 8 and then discharged into the collection ditch for treatment.
[0056] like Figure 3 and Figure 4 As shown, the drainage trough 8 includes a top cover 9 with a concave top surface and drainage holes 91 extending through it from top to bottom. The top of the trough 8 is open, and two sides of the top opening are provided with sunken steps for supporting the top cover 9. The top cover 9 is configured to support the sunken steps on both sides. If the drainage rate of the UHPC inorganic grinding stone layer 7 and the porous low-shrinkage concrete layer 6 is insufficient, water from the garage ramp surface will flow downstream through the top cover 9 and into the drainage trough 8 through the drainage holes 91 for collection and treatment.
[0057] like Figure 2 、 Figure 3 As shown, it also includes a plain soil base layer 2, a crushed stone cushion layer 3, a concrete layer 4, and a waterproof layer 5 arranged in sequence from the bottom to the surface; the upper surface of the waterproof layer 5 is provided with a hydrophobic coating; the waterproof layer 5 is located below the porous low-shrinkage cement layer 6.
[0058] The base soil layer 2 is made of plain soil and compacted to a compaction coefficient of 93% or greater, providing better support for the upper layer, preventing settlement, and also improving the ability to prevent water penetration and erosion. The crushed stone cushion layer 3 is further compacted before the concrete layer 4 is laid. The crushed stone cushion layer 3 improves the bonding effect between the concrete layer 4 and the underlying layer and improves the support effect. The concrete layer 4 itself has good structural strength and waterproof performance, but it cannot avoid the presence of cracks. Therefore, in this embodiment, a waterproof layer 5 is added. The waterproof layer 5 serves to prevent underground water from seeping out of the ground surface, while also preventing surface water from seeping in.
[0059] By providing a hydrophobic coating on the surface of the waterproof layer 5 in contact with the porous low-shrinkage concrete layer 6, the difficulty of water flowing between the two interfaces of the porous low-shrinkage concrete layer 6 and the waterproof layer 5 is reduced, thereby avoiding the accumulation of accumulated water in the porous low-shrinkage concrete layer 6 for a long time and facilitating the rapid discharge of accumulated water from the porous low-shrinkage concrete layer 6.
[0060] The plain soil base layer 2 and the crushed stone cushion layer 3 are laid and compacted in sequence. A steel mesh is provided in the concrete layer 4 and / or the porous low-shrinkage concrete layer 6. The diameter of the steel bars in the steel mesh is 6 mm. The porous low-shrinkage concrete layer 6 and the UHPC inorganic grinding stone layer 7 are treated with an interface agent to enhance the bonding performance.
[0061] For further optimization, the thickness of the concrete layer 4, the thickness of the porous low-shrinkage concrete layer 6, and the thickness of the UHPC inorganic grinding stone layer 7 decrease in sequence.
[0062] Example 2:
[0063] This embodiment provides a channel water blocking device that can be applied to the above-mentioned garage waterproof floor, such as being set at the entrance and exit of the garage ramp to prevent water accumulation and flooding from flowing into the underground garage; Figures 5 to 8 As shown, it includes a water baffle 03, a sealing gasket 02, a fixing plate 01 and a limiting column 04. The lower section of the water-facing surface of the water baffle 03 is connected to one end of the sealing gasket 02 through the fixing plate 01, and the other end of the sealing gasket 02 is connected to the floor on the water-facing side of the water baffle 03 through another fixing plate 01. The bottom of the water baffle 03 is rotatably connected to both sides of the channel and / or the floor, and a limiting column 04 is provided on the channel on the back water side of the water baffle 03; when the channel is in a water-blocking state, the water baffle 03 rotates upward so that the back water surface of the water baffle 03 abuts against the limiting column 04; when the channel is in a passable state, the water baffle 03 rotates downward so that the water-facing surface of the water baffle 03 abuts against the floor of the channel.
[0064] Further optimization also includes a locking groove 05 and a locking rod 06. The locking groove 05 is located on the channel wall on the water-facing side of the water baffle 03, and the locking rod 06 is rotatably installed in the locking groove 05; when the channel is in a passable state, the locking rod 06 is retracted in the locking groove 05; when the channel is in a water-blocking state, the locking rod 06 rotates to extend out of the locking groove 05 and abut against the water-facing side of the water baffle 03 to limit the water baffle 03 from rotating in the direction away from the limit column 04.
