Description

Technical Field

[0001] This utility model relates to the field of waterproofing engineering technology, and more specifically, it relates to a water-stopping node structure for underground connection openings. Background Technology

[0002] With the continuous development of urban underground space, underground connection points, as key components connecting different underground buildings, have crucial waterproofing performance. Whether it is the passage between subway stations, the connecting area of ​​underground shopping malls, or the interchange of underground parking lots, once a water leakage problem occurs, it will not only affect the durability of the structure, but may also cause safety hazards such as electric leakage and interfere with the normal use of underground space. Traditional waterproofing measures are often unable to effectively guarantee the waterproofing effect. Therefore, it is urgent to develop a reliable water-stop node structure for underground connection points.

[0003] For the reasons mentioned above, how to effectively ensure the waterproofing effect of the underground connection water-stop node structure is the problem that this application considers. Utility Model Content

[0004] To address the shortcomings of existing technologies, a waterproof joint structure for underground connections is provided, which can effectively ensure the waterproof performance of the waterproof joint structure for underground connections.

[0005] To achieve the above objectives, the following technical solution is provided: a water-stop node structure for underground connection openings, characterized in that it includes a base layer, a waterproof structure disposed at the connection node of adjacent base layers, a protective layer connected to the waterproof structure, and a filling component disposed in the gap of the waterproof structure, wherein the protective layer is used to protect the waterproof structure, and the filling component is used to cooperate with the waterproof structure to compensate for the waterproof effect;

[0006] The waterproof structure includes a steel plate waterstop, a centrally embedded rubber waterstop, a roll waterproof layer, and a top waterproof layer. The centrally embedded rubber waterstop is located above the steel plate waterstop and is embedded in the base layer on both sides of the gap.

[0007] The top slab waterproof layer and the steel plate waterstop are located on the upper and lower sides of the base layer, respectively; the roll waterproof layer is located between the top slab waterproof layer and the base layer.

[0008] In a further optimization of this utility model, the protective layer includes a mortar isolation layer and a fine stone concrete protective layer. The mortar isolation layer is laid on top of the waterproof layer of the roof slab and is used to isolate the waterproof layer of the roof slab from direct contact with the fine stone concrete protective layer.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0017] Reference Figure 1As shown, the underground connection water-stop node structure includes a base layer 1, a waterproof structure 2 set at the connection node of adjacent base layers 1, a protective layer 3 connected to the waterproof structure 2, and a filling component 4 set in the gap of the waterproof structure 2. The protective layer 3 is used to protect the waterproof structure 2, and the filling component 4 is used to cooperate with the waterproof structure 2 to compensate for the waterproof effect.

[0018] The waterproof structure 2 includes a steel plate waterstop 21, a centrally embedded rubber waterstop 22, a roll waterproof layer 23, and a top waterproof layer 24. The centrally embedded rubber waterstop 22 is located above the steel plate waterstop 21 and is embedded in the base layer 1 on both sides of the gap.

[0019] The top slab waterproof layer 24 and the steel plate waterstop 21 are located on the upper and lower sides of the base layer 1, respectively; the roll waterproof layer 23 is located between the top slab waterproof layer 24 and the base layer 1.

[0020] In existing technologies, conventional underground connection water-stop joint structures suffer from the following defects, making them unusable: waterproof joint structures typically employ a single waterproof component or a combination of multiple identical waterproof components. The use of a single waterproof material results in a lack of other characteristics in the waterproof joint structure. Now, multiple waterproof components with different characteristics are used to form the waterproof joint structure. Utilizing the various properties of different waterproof components, additional waterproof joint structure characteristics are added, such as sound insulation, heat insulation, and shock absorption. This allows the waterproof joint structure to be suitable for different applications. Simultaneously, the protective layer 3 protects the waterproof structure 2. The waterproof structure 2 initially prevents liquid from flowing underground, starting with the easily installable top waterproof layer and the rolled waterproof layer 23. A small portion of the liquid that flows in is then waterproofed by the steel plate waterstop 21 and the embedded rubber waterstop 22. This extends the service life and maintains the waterproof effect of materials that are difficult to install but have strong waterproof performance, thus effectively ensuring the waterproof effect of the underground connection water-stop joint structure.

[0021] Reinforcing bars are added to the base layer 1 to bear the tensile force generated under various stress conditions, preventing cracks or breaks in the base layer 1. The top waterproof layer 24 is set at the top of the waterproof structure 2 to prevent rainwater and other corrosive liquids from penetrating and to prevent the waterproof structure 2 below the top waterproof layer 24 from being eroded by water for a long time, which would weaken the waterproof effect. At the same time, the top waterproof layer 24 can also play a certain role in heat insulation, reducing the amount of external heat entering the base layer 1, thereby reducing the impact of thermal expansion and contraction on the base layer 1 and the rest of the waterproof structure 2.

[0022] The roll waterproofing layer 23 is installed below the top waterproofing layer 24. Because the roll waterproofing layer 23 has anti-seepage properties, it can prevent pressurized water from penetrating through the top waterproofing layer 24 to the embedded rubber waterstop 22. At the same time, the roll waterproofing layer 23 has flexibility and tensile strength, and can deform with the base layer 1. It will not easily break when the base layer 1 deforms, thus maintaining the integrity of the waterproofing. The roll waterproofing layer 23 also has puncture resistance and abrasion resistance, and can resist external damage, protecting the waterproofing function of the embedded rubber waterstop 22 from being affected.

[0023] The embedded rubber waterstop 22 is flexible. It expands and contracts with external factors such as temperature changes or foundation settlement, without being broken or damaged, thus maintaining the continuity of waterproofing. The embedded rubber waterstop 22 also has waterproof and seepage-resistant properties, preventing water and corrosive liquids from flowing into the steel plate waterstop 21, preventing rust and corrosion caused by water and corrosive liquids, thereby extending the service life of the steel plate waterstop 21. Simultaneously, the embedded rubber waterstop 22 is elastic, acting as a buffer and shock absorber for the waterproof structure 2. By absorbing and dissipating the energy generated during vibration of the waterproof structure 2 and the base layer 1, it reduces the impact of vibration on the waterproof structure 2, thus protecting the integrity of the inflexible steel plate waterstop 21. Furthermore, its elastic material properties can block the transmission of noise generated by vibration of the base layer 1 through gaps, reducing noise transmission to a certain extent. For example, in the connection parts of subway tunnels, the embedded rubber waterstop 22 can absorb the vibration energy generated by the train during operation, reducing the risk of vibration damage to the tunnel structure. In some buildings with high noise requirements, such as hospitals and schools, it can reduce the spread of noise to a certain extent.

[0024] Since the embedded rubber waterstop 22 can only block liquid flowing in from the direction of the gap, it may not be effective in blocking seepage from other directions. Therefore, the steel plate waterstop 21 is set at the bottom of the waterproof structure 2. Through its impermeability, it is used to block liquid seepage from multiple directions. At the same time, the steel plate waterstop 21 has rigidity and plays a role in connecting and reinforcing the waterproof structure 2. During use, the base layer 1 may deform due to factors such as temperature changes and foundation settlement. The steel plate waterstop 21 buffers the stress changes of the structure through its own slight deformation, avoiding cracking and leakage of the base layer 1 caused by structural deformation.

[0025] The protective layer 3 includes a mortar isolation layer 31 and a fine stone concrete protective layer 32. The mortar isolation layer 31 is laid on top of the waterproof layer 24 of the top slab and is used to isolate the waterproof layer 24 of the top slab from direct contact with the fine stone concrete protective layer 32. The fine stone concrete protective layer 32 is laid on the mortar isolation layer 31 and is used to protect the waterproof structure 2.

[0026] The mortar isolation layer 31 isolates the fine aggregate concrete protective layer 32 from the top slab waterproof layer 24. When the fine aggregate concrete protective layer 32 deforms due to external temperature changes or other reasons, the mortar isolation layer 31 makes the top slab waterproof layer 24 and the fine aggregate concrete protective layer 32 relatively independent, each deforming without affecting the other. In subsequent use, such as material handling and personnel movement, the mortar isolation layer 31 can buffer the mechanical damage to the waterproof structure 2, reducing the damage to the waterproof structure 2. At the same time, the mortar isolation layer 31 initially prevents dust and debris from flowing into the waterproof structure 2, and also avoids the corrosion of the waterproof structure 2 by chemical substances in other materials, extending the service life of the waterproof structure 2. The mortar isolation layer 31 provides a flat base surface for the subsequent construction of the fine aggregate concrete protective layer 32, ensuring the uniform thickness of the fine aggregate concrete layer and avoiding problems such as uneven thickness and stress concentration caused by uneven base surface, thereby improving the overall quality of the fine aggregate concrete protective layer 32.

[0027] The fine aggregate concrete protective layer 32 has anti-aging and anti-corrosion properties, which can protect the waterproof structure 2 from accelerated aging, cracking, embrittlement, and other phenomena, and extend the service life of the waterproof structure 2. At the same time, the fine aggregate concrete also has strength and rigidity, which can resist the damage caused to the waterproof structure 2 by external mechanical impact and friction, such as material handling and personnel movement. When deformation occurs due to factors such as temperature changes and foundation settlement, the fine aggregate concrete protective layer 32 can disperse and resist the stress generated by these deformations through its own crack resistance, reducing the possibility of cracks appearing in the waterproof structure 2. Even if the waterproof structure 2 undergoes a certain degree of deformation, the fine aggregate concrete protective layer 32 and the steel plate waterstop 21 work together to limit the further development and extension of cracks at the top and bottom, thereby ensuring the waterproof effect of the waterproof structure 2.

[0028] The filling component 4 includes a foam plastic rod 41, which is positioned to correspond to the gap between adjacent base layers 1 and is located above the top waterproof layer 24. It is used to cooperate with the top waterproof layer 24 and the roll waterproof layer 23 to compensate for the waterproof effect at the gap.

[0029] The foam plastic rod 41 is elastic and flexible, and maintains good sealing performance through its own material properties, so that the mortar isolation layer 31 and the top waterproof layer 24 can be tightly connected, preventing rainwater and other corrosive liquids from penetrating into the waterproof structure 2, thereby extending the service life of the waterproof structure 2. In areas prone to vibration or collision, the foam plastic rod 41 acts as a buffer material, which can absorb and alleviate the stress generated by deformation or vibration, and prevent the waterproof structure 2 and the protective layer 3 from being damaged by mutual squeezing or collision. At the same time, the porous structure of the foam plastic rod 41 can effectively absorb and block the transmission of sound, which helps to reduce noise.

[0030] The number of foam plastic rods 41 is at least one.

[0031] Multiple foam rods 41 can enhance the connection between the protective layer 3 and the waterproof structure 2, while compensating for the waterproof effect of the waterproof structure 2. Multiple foam rods 41 can also insulate some heat. Installed in the waterproof structure 2 and the protective layer 3, they reduce the heat transfer from the outside to the protective layer 3.

[0032] The filling component 4 also includes polystyrene strips 42, two of which are provided. The polystyrene strips 42 are located on the upper and lower sides of the embedded rubber waterstop 22 respectively, and fill the gaps between adjacent base layers 1.

[0033] The polystyrene strip 42 is waterproof, preventing external moisture from flowing into the embedded rubber waterstop 22 through gaps. It also possesses good elasticity and flexibility, providing cushioning and protection for the embedded rubber waterstop 22. Furthermore, its extremely low thermal conductivity effectively prevents heat transfer through the protective layer 3 to the embedded rubber waterstop 22, mitigating temperature changes around it. The polystyrene strip 42 contains numerous closed pores that effectively absorb and reflect sound. Combined with the foam rod 41, it reduces sound propagation while maintaining waterproofing. In environments with high acoustic requirements, such as conference rooms and recording studios, the underground connection waterstop structure of this invention, in conjunction with other sound insulation materials, can improve the indoor acoustic environment while ensuring waterproofing, reducing echoes and noise pollution, and ensuring clear and pure sound.

All technical solutions falling within the scope of this utility model's concept are protected.
