Description

Technical Field

[0001] The utility model relates to the waterproof field of post-cast type manure outlets in building pig houses, in particular to a waterproof structure applied to post-cast type manure outlets in building pig houses. Background Art

[0002] Multi-story piggery farming technology is a recent development. The environment in multi-story piggeries is characterized by corrosion and chronic waterlogging, and the manure outlets within the manure ditch are often a source of leakage. The waterproofing required for multi-story piggery farming differs from that of ordinary residential buildings (kitchens, bathrooms, pools, etc.). After the civil construction is completed, a large number of slatted floor panels, equipment, and production loads (fattening pigs) must be added. This can easily lead to slight deformations in the waterproofing structure. Furthermore, manure ditch drainage typically utilizes a siphon method, which often causes significant vibration in the pipes, significantly damaging and impacting the waterproofing layer around the manure outlets. In particular, many multi-story piggery sewage pipes are currently constructed using PVC plastic pipes, and the manure outlets are often cast in a secondary process, without the use of waterstop rings. Consequently, traditional detailed additional layer treatments are prone to hollowing and poor resistance to prolonged vibration, resulting in cracking and delamination. This results in poor waterproofing at the post-cast manure outlets in multi-story piggeries, making them prone to leakage. Summary of the Invention

[0003] In order to improve the waterproof performance and waterproof effect of the post-poured manure outlet of a building pig house, the utility model provides a waterproof structure applied to the post-poured manure outlet of a building pig house. The utility model forms three waterproof layers, namely a base treatment layer, a butyl tape layer, and a polyurethane waterproof layer, by successively constructing the post-poured manure outlet of the building pig house. The three waterproof layers greatly improve the waterproof performance and waterproof effect of the post-poured manure outlet of the building pig house.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] The embodiment of the utility model discloses a waterproof structure for a post-cast manure outlet of a pig house in a building.

[0026] Reference Figure 1 The waterproof structure comprises a base layer 1, a manure pipe 2, a base treatment layer 3, a butyl tape layer 4, a polyurethane waterproof layer 5 and a post-pouring layer 6.

[0027] The structural base 1 can be a building of a building or other concrete structure reserved for construction in advance. The structural base 1 is a recessed structure with a through hole in the middle. The manure pipe 2 is passed through the through hole, and the top of the manure pipe 2 is exposed and higher than the top of the structural base 1 around it.

[0028] Reference Figure 1 The base treatment layer 3 is coated with a base treatment agent. When in use, the base treatment agent can be applied to the inner surface of the through hole of the structural base 1, and then the manure pipe 2 is installed at the through hole of the structural base 1. The base treatment agent bonds the manure pipe 2 to the structural base 1. After the base treatment agent solidifies, the base treatment layer 3 is formed. The base treatment layer 3 forms the first layer of waterproofing between the manure pipe 2 and the structural base 1. The base treatment agent can be selected from one or more of epoxy resin treatment agent, acrylic emulsion treatment agent, polyurethane base treatment agent and GES-M1 base treatment agent. In this embodiment, the base treatment agent is selected from GES-M1 base treatment agent or EP206 base treatment agent. In other embodiments, the base treatment agent can also be selected from other base treatment agents in addition to the above-mentioned base treatment agents.

[0029] Among them, GES-M1 base treatment agent has the following characteristics:

[0030] 1. It has a significant effect on reinforcing and sealing the base structure, especially the damp base. It can effectively improve the bonding strength between the waterproof layer or additional layer product and the base, ensuring the durability of the waterproof coating.

[0031] 1. Water resistance: The product is water-resistant and can be used on wet substrates with significant effects.

[0032] 2. Self-emulsification function: After the two components are mixed evenly, they can self-emulsify and are easy to use.

[0033] 3. Reinforcement and sealing effect: It has a good effect on the reinforcement and sealing construction of the base.

[0034] Reference Figure 1The butyl tape layer 4 is laid above the base treatment layer 3 and extends to the outer wall of the manure pipe 2 near the base treatment layer 3. The butyl tape layer 4 covers the base treatment layer 3 and the outer wall of the manure pipe 2. The butyl tape layer 4 is laid using butyl tape, which can be single-sided butyl tape or double-sided butyl tape, or both. In this embodiment, single-sided butyl tape is used, and BR-706 high-elongation butyl tape or BR-704 butyl tape is selected for laying. The butyl tape layer 4 forms a second waterproof layer between the manure pipe 2 and the structural base 1.

[0035] Among them, BR-706 high elongation butyl tape has the following characteristics:

[0036] 1. Good ductility and base bonding performance, can well adapt to the deformation and vibration of the pipe root to ensure the durability of the overall waterproof layer.

[0037] 2. Excellent mechanical properties: BR-706 high elongation butyl tape has high bonding strength and tensile strength, good elasticity and elongation, and strong adaptability to interface deformation and cracking.

[0038] 3. Stable chemical properties: The tape has excellent chemical resistance, weather resistance and corrosion resistance, and can withstand various harsh environments.

[0039] 4. Reliable application performance: BR-706 high elongation butyl tape has good adhesion, waterproofness, sealing, low temperature resistance and dimensional stability.

[0040] 5. Simple construction process: The construction operation process of this tape is simple, easy to handle and paste, and suitable for various application scenarios.

[0041] Reference Figure 1 The polyurethane waterproof layer 5 is applied to the butyl tape layer 4 and the structural base layer 1. The polyurethane waterproof layer 5 is formed by applying a polyurethane waterproof coating. Preferably, the polyurethane waterproof layer 5 can be applied by applying one or both of a single-component polyurethane waterproof coating and a two-component polyurethane waterproof coating. In this embodiment, the polyurethane waterproof layer 5 is a two-component polyurethane waterproof coating, and the two-component polyurethane waterproof coating is selected from SPU-311 two-component polyurethane waterproof coating. The polyurethane waterproof layer 5 forms a third waterproof layer between the manure pipe 2 and the structural base layer 1. In other embodiments, the polyurethane waterproof layer 5 can also be made of SPU-301 single-component polyurethane waterproof coating.

[0042] Among them, SPU-311 two-component polyurethane waterproof coating has the following characteristics:

[0043] 1. It is a continuous, flexible, seamless rubber waterproof layer. As a polymer product, it can adapt to the corrosiveness of manure and urine in the manure ditches of buildings and pig houses.

[0044] 2. High strength and excellent ductility: The coating has high strength and excellent ductility, which can adapt to the slight deformation of the base layer and prevent cracks;

[0045] 3. Water resistance and durability: It has excellent water resistance and weather resistance, and can maintain stable waterproof performance in harsh environments such as humidity and temperature changes;

[0046] 4. Good flexural strength, tensile strength and compressive strength: waterproof, qualified tear strength and good elongation at break.

[0047] Reference Figure 1 During the construction of the polyurethane waterproof layer 5, the polyurethane waterproof layer 5 is evenly coated on the butyl tape layer 4 and the structural base layer 1 near the butyl tape layer 4, and the polyurethane waterproof layer 5 extends to a distance near the recessed structural base layer 1. This distance can be freely controlled by the user, such as forming a ring with a diameter of 0.5 meters with the axis of the sewage pipe 2 as the center.

[0048] During the construction of the polyurethane waterproof layer 5, the thickness of the polyurethane waterproof layer 5 can be constructed to be between 1.5 mm and 2 mm. In this embodiment, the thickness of the polyurethane waterproof layer 5 is preferably 1.5 mm.

[0049] The post-cast layer 6 is poured on the sunken structural base layer 1 . The post-cast layer 6 is located above the polyurethane waterproof layer 5 . The post-cast layer 6 can be formed by pouring concrete.

[0050] This waterproof structure offers excellent waterproofing, strong vibration and tear resistance, and is not easily damaged. It effectively waterproofs the post-cast manure outlets in high-rise piggeries, reducing the risk of leakage there. Through the construction of three waterproof layers, it forms a complete waterproof system at the root of the pipe at the post-cast manure outlet. It combines the strength of waterproof membranes with the ease of application of coatings, and is well adapted to the vibration of the pipe root and the corrosive nature of the manure ditches in high-rise piggeries.

[0051] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
