Abstract
Description
Technical Field
[0001] The present application relates to the technical field of drainage structures, and in particular to a combined pipe drainage structure. Background Art
[0002] Most balconies extend outside the building and are directly exposed. In order to protect the building from waterproofing, drain pipes are installed at the corners of the balcony to achieve effective drainage function.
[0003] However, due to the difference in expansion coefficient between the drainage pipe and reinforced concrete, the junction of the two often becomes a potential leak point. In order to further improve the anti-leakage effect of the balcony during the drainage process, the waterproofing project pays special attention to the details of the waterproof material extending from the ground to the inside of the drainage pipe during implementation. However, according to previous construction experience, when the waterproof material is wrapped around the drainage pipe, if the depth is insufficient, it is very easy to cause cracks at the joints, thereby destroying the waterproofing effect; on the contrary, if the covering is too deep, it not only increases the difficulty of construction, but may also cause blockage problems due to the dripping of waterproof materials into the pipe.
[0004] At present, waterproofing projects at drainage pipe joints are mostly implemented by different waterproofing engineering teams. Due to differences in professional level and construction experience among the teams, it is often difficult to ensure consistency in waterproofing effects. Summary of the invention
[0005] In order to improve the drainage efficiency of the drainage structure and enhance the anti-leakage effect, the present application provides a combined pipe anti-drainage structure.
[0006] The present application provides a combined pipe waterproofing and drainage structure, which adopts the following technical solutions:
[0007] A combined pipe waterproofing and drainage structure comprises a brick wall, wherein a leveling layer is arranged on the surface of the brick wall, a waterproof layer and facing bricks are arranged on the top surface of the leveling layer in sequence, a covering agent is applied on the surface of the facing bricks, a floor drain is arranged on the floor of the balcony, and the leveling layer is provided with a downward slope towards the floor drain.
[0008] By adopting the above-mentioned technical scheme, the stacking arrangement of brick walls, leveling layers, waterproof layers, facing tiles and covering agents can achieve multiple waterproof protection effects. The present application sets a downward slope from the leveling layer to the floor drain to ensure smooth discharge of water, effectively reduce water accumulation, and improve the drainage efficiency of the balcony.
[0009] Preferably, the area of the brick wall where the original thermal insulation layer is removed is provided with a reinforcing agent at the base reinforcement treatment point.
[0010] By adopting the above technical solution, in the brick wall area where the original thermal insulation layer is removed, the base layer is reinforced with a reinforcing agent, thereby enhancing the structural stability of the wall.
[0011] Preferably, the base reinforcement treatment points include water leakage points and cracks penetrating the floor slab, the water leakage points are filled with epoxy reinforcement agent, and the cracks penetrating the floor slab are filled with high-elastic polymer grouting material.

By filling the leaking points with epoxy reinforcement and the cracks through the floor slabs with high-elastic polymer grouting material, the leaks and cracks can be effectively blocked, and the water can be effectively reduced from penetrating into the balcony floor through the weak links, thereby improving the waterproof effect.
[0013] Preferably, the slope of the leveling layer in the area of the balcony floor where no drain outlet is provided is greater than 2%.
[0014] By adopting the above technical solution, in the area where no drainage outlet is set on the balcony floor, the slope of the leveling layer is designed to be greater than 2%. Such a design can ensure that in the case of light rain or clean water, the water flow can naturally converge to the floor drain, reducing the problem of water accumulation caused by flat terrain.
[0015] Preferably, the slope of the leveling layer in the area where the drainage pipe is arranged on the balcony floor is greater than 4%.
[0016] By adopting the above technical solution, in the balcony floor area where the drainage pipe is installed, the slope of the leveling layer is designed to be greater than 4%. The larger slope can ensure that even in the case of a large water flow, the water flow can be quickly directed to the drainage pipe, thereby reducing water accumulation or leakage caused by poor drainage and improving the efficiency of the drainage system.
[0017] Preferably, the slope of the leveling layer in the area where the floor drain is arranged on the balcony floor is greater than 3%.
[0018] By adopting the above technical solution, the slope of the leveling layer in the balcony floor area where the floor drain is set is designed to be greater than 3%. This moderate slope not only ensures that water can flow smoothly into the floor drain, but also reduces problems such as rapid water flow and splashing caused by excessive slope, making the balcony drainage system more stable and reliable.
[0019] Preferably, a reserved hole is provided in the area where the drain pipe passes through the balcony floor, and the reserved hole is embedded with micro-expansive concrete.
[0020] By adopting the above technical solution, the micro-expansive concrete can produce micro-expansion during the curing process. A reserved hole is set in the area where the drainage pipe passes through the balcony floor, and the micro-expansive concrete is embedded, so that the gap is filled more tightly, reducing the infiltration of water through these gaps, thereby greatly improving the waterproof effect.
[0021] Preferably, the outer wall of one end of the drainage pipe close to the floor drain is covered with a layer of sealant, and the micro-expansive concrete is arranged outside the sealant.
[0022] By adopting the above technical solution, the outer wall of one end of the drain pipe close to the floor drain is covered with sealant, and micro-expansive concrete is arranged on the outside thereof, thereby forming a double sealing protection. The sealant can fit tightly to the outer wall of the drain pipe to provide an additional waterproof barrier, while the micro-expansive concrete further strengthens the sealing effect, thereby effectively enhancing the sealing effect at the connection between the drain pipe and the floor drain.
[0023] Preferably, the waterproof layer is an asphalt polyurethane waterproof layer.
[0024] By adopting the above-mentioned technical scheme, the asphalt polyurethane material is both water-resistant and corrosion-resistant, and can effectively resist the erosion of external moisture and harmful substances. This application uses asphalt polyurethane as the waterproof layer material to make the balcony more waterproof. At the same time, its good elasticity and wear resistance further enhance the durability and stability of the waterproof layer, providing reliable protection for the entire drainage structure.
[0025] Preferably, a flange is provided at the corner of the balcony floor near the floor drain, the flange is a C20 fine stone concrete flange, and the flange height is greater than 150 mm.
[0026] By adopting the above technical solution, the flange can effectively guide water to flow smoothly into the floor drain, reducing water accumulation or splashing at the corners. At the same time, the strength and durability of C20 fine stone concrete help to improve the stability of the flange structure.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] The following is combined with Figure 1-3 This application is described in further detail.
[0036] The embodiment of the present application discloses a combined pipe drainage structure.
[0037] Reference Figure 1 and Figure 2 A combined pipe waterproofing and drainage structure comprises a brick wall 1, a leveling layer 2 is arranged on the surface of the brick wall 1, a waterproof layer 3 and facing bricks 4 are arranged on the top surface of the leveling layer 2 in sequence, a covering agent 5 is applied on the surface of the facing bricks 4, a floor drain 82 is arranged on the floor of the balcony, and a downward slope is arranged on the leveling layer 2 toward the floor drain 82. In the present application, the stacked arrangement of the brick wall 1, the leveling layer 2, the waterproof layer 3, the facing bricks 4 and the covering agent 5 can achieve the effect of multiple waterproof protection. The present application ensures the smooth discharge of water by setting a downward slope on the leveling layer 2 toward the floor drain 82, effectively reduces the water accumulation phenomenon, and improves the drainage efficiency of the balcony.
[0038] Specifically, the area of the original thermal insulation layer of the brick wall 1 is removed, the surface is cleaned, the leaking points and the cracks running through the floor slab are exposed, and then a reinforcing agent is set at these base reinforcement treatment points.
[0039] The base reinforcement treatment points include leaking points and cracks penetrating through the floor slab. The leaking points are filled with epoxy reinforcing agent, and the cracks penetrating through the floor slab are filled with high-elastic polymer grouting material. Both epoxy reinforcing agent and high-elastic polymer grouting material have excellent elasticity and sealing properties. By filling the leaking points with epoxy reinforcing agent and the cracks penetrating through the floor slab with high-elastic polymer grouting material, the leaks and cracks can be effectively sealed, and the infiltration of moisture into the balcony floor through weak links can be effectively reduced, thereby improving the waterproof effect.
[0040] In the present application, in the area of the brick wall 1 where the original thermal insulation layer is removed, the base layer is reinforced with a reinforcing agent to enhance the structural stability of the wall. Such treatment can prevent leakage problems caused by loosening or aging of the wall and improve the overall waterproof performance.
[0041] Reference Figure 2 and Figure 3 According to the actual height of the building, multiple balconies are arranged. The floor of each balcony adopts roughly the same waterproof treatment method. The difference is that the floor of the balcony located on the top floor is provided with a floor drain 82, and the floor of the balcony located on the second floor is provided with a drainage pipe 81, so that the top of the drainage pipe 81 is closely connected with the floor drain 82; in addition, the scene arrangement is also performed for the balcony floor that is not provided with a drainage pipe 81 or a floor drain 82 (refer to Figure 1 ).
[0042] Specifically, the slope of the leveling layer 2 in the area where the balcony floor is not provided with a drain outlet is greater than 2%; the slope of the leveling layer 2 in the area where the balcony floor is provided with a floor drain outlet 82 is greater than 3%; the slope of the leveling layer 2 in the area where the balcony floor is provided with a drain pipe 81 is greater than 4%.
[0043] In the present application, in the area where no drain outlet is provided on the balcony floor, the slope of the leveling layer 2 is designed to be greater than 2%. Such a design can ensure that in the case of light rain or clean water, the water flow can naturally converge to the floor drain 82, reducing the problem of water accumulation caused by the flat terrain; in the area of the balcony floor where the floor drain 82 is provided, the slope of the leveling layer 2 is designed to be greater than 3%. This moderate slope not only ensures that water can flow smoothly into the floor drain 82, but also reduces the problems of fast water flow and splashing caused by excessive slope, making the balcony drainage system more stable and reliable; in the area of the balcony floor where the drain pipe 81 is provided, the slope of the leveling layer 2 is designed to be greater than 4%. The larger slope can ensure that even in the case of a large water flow, the water flow can be quickly guided to the drain pipe 81, reducing water accumulation or leakage caused by poor drainage, and improving the efficiency of the drainage system.
[0044] Further, refer to Figure 2 and Figure 3A reserved hole 61 is provided in the area where the drain pipe 81 passes through the balcony floor. The outer wall of one end of the drain pipe 81 close to the floor drain 82 is covered with a layer of sealant 63. Micro-expansive concrete 62 is embedded in the reserved hole 61, so that the micro-expansive concrete 62 is arranged outside the sealant 63. The micro-expansive concrete 62 can produce micro-expansion during the curing process. A reserved hole 61 is provided in the area where the drain pipe 81 passes through the balcony floor, and the micro-expansive concrete 62 is embedded. Under the joint action of the sealant 63 and the micro-expansive concrete 62, double sealing protection is formed, so that the sealant 63 can fit tightly against the outer wall of the drain pipe 81 to provide an additional waterproof barrier, and the micro-expansive concrete 62 further strengthens the sealing effect, so that the gap is filled more tightly, thereby effectively enhancing the sealing effect of the connection between the drain pipe 81 and the floor drain 82.
[0045] In the present application, the waterproof layer 3 is an asphalt polyurethane waterproof layer 3. The asphalt polyurethane material is both water-resistant and corrosion-resistant, and can effectively resist the erosion of external moisture and harmful substances. The present application uses asphalt polyurethane as the waterproof layer 3 material to make the balcony more waterproof. At the same time, its good elasticity and wear resistance further enhance the durability and stability of the waterproof layer 3, providing reliable protection for the entire drainage structure.
[0046] In addition, a flange 7 is provided at the corner of the balcony floor near the floor drain 82. The flange 7 is a C20 fine stone concrete flange 7. The height of the flange 7 is greater than 150 mm. The flange 7 can effectively guide the water to flow smoothly into the floor drain 82 and reduce the accumulation or splashing of water at the corner. At the same time, the strength and durability of the C20 fine stone concrete help to improve the stability and long life of the flange 7 structure.
[0047] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
