Abstract
Description
Technical Field
[0001] The present application relates to the technical field of deformation joint waterproofing, for example, to a deformation joint waterproofing structure of an underground structure. Background Art
[0002] Waterproofing technical measures are very important and indispensable in underground projects. Underground projects include underground tunnels, basements, underground pipelines, etc. In these projects, there are many challenges such as groundwater, underground humidity, and the contact between underground structures and the surrounding environment. Without effective waterproofing technical measures, underground projects may be affected by a series of negative effects. The application of waterproofing technical measures can effectively prevent the damage caused by groundwater leakage.
[0003] The waterproofing of traditional deformation joints of underground structures mainly relies on waterproof boards and waterproof membranes. The waterproof boards are covered with waterproof membranes and then buried in the prefabricated half layer of the underground structure. Although the waterproof boards have the ability to stretch as the deformation joints deform, their tensile strength is limited, and the tensile fatigue resistance nodes are low and can be easily torn off, which lacks durability and affects the waterproofing effect. Utility Model Content
[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.
[0005] The disclosed embodiment provides a waterproof structure for deformation joints of underground structures to solve the problems of poor tensile strength, insufficient durability and poor waterproof quality of waterproof materials.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A waterproof structure for deformation joints of an underground structure comprises a first bottom plate layer, a second bottom plate layer, a first concrete plate layer, a second concrete plate layer, a waterproof roll material, and an arc bottom pipe. A first concrete plate layer is provided at the bottom of the first bottom plate layer, and a second concrete plate layer is provided at the bottom of the second bottom plate layer. The first bottom plate layer and the first concrete plate layer correspond to the second bottom plate layer and the second concrete plate layer respectively and deformation joints are provided between them. Two layers of waterproof roll materials are provided between the first bottom plate layer and the first concrete plate layer. The waterproof roll materials are also extended and laid between the second bottom plate layer and the second concrete plate layer. The upper layers of the two layers of waterproof roll materials are arched upward at the deformation joint, and the lower layer of the waterproof roll materials is arched downward at the deformation joint. The two layers of waterproof roll materials enclose a space at the deformation joint position, and foam strips are filled in the space. The foam strips play an elastic supporting role on the two layers of waterproof roll materials, and the deformation joint is based on the principle of thermal expansion and contraction. When deformation occurs, the waterproof membrane will be stretched, and the arched part of the waterproof membrane in the deformation joint can be used as the margin for pulling when the deformation joint is deformed, which can effectively prevent the waterproof membrane from being torn off during the deformation of the deformation joint, affecting the service life and waterproof quality of the waterproof structure. An arc-shaped bottom tube is arranged at the bottom end of the deformation joint. The arc-shaped bottom tube is a semicircular arc with the convex surface facing upward, and the two ends respectively contact the opposite side walls of the first concrete slab layer and the second concrete slab layer. The arc-shaped bottom tube can further prevent moisture from seeping upward, ensuring that the deformation joint waterproof structure can fully prevent groundwater infiltration. The arc-shaped bottom tube is made of elastic material and has tensile strength itself. The arc-shaped bottom tube and the waterproof membrane can cooperate to fully prevent groundwater from seeping, and both have flexible tensile strength, thereby ensuring sufficient durability, waterproof quality and service life.
[0008] Furthermore, the deformation joint is fully filled with caulking agent, which plays a basic role in waterproofing and moisture return, thereby increasing the quality of preventing groundwater penetration.
[0009] Furthermore, side ears are provided at both ends of the arc-shaped bottom tube, and a number of buckle ear plates are provided on the side ears corresponding to the arc-shaped bottom tube on the inner sides of the bottoms of the first concrete slab layer and the second concrete slab layer, and the buckle ear plates are buckled with the corresponding side ears, thereby fixing the position of the arc-shaped bottom tube. No matter whether the arc-shaped bottom tube is stretched or compressed during the deformation of the deformation joint, it will not separate from the deformation joint, thereby ensuring the stability of waterproof penetration.
[0010] Furthermore, a T-shaped buckle plate is buckled at the bottom of the deformation joint to seal the top of the deformation joint. The middle part of the T-shaped buckle plate is buckled into the deformation joint, and the two ends are respectively arranged on the sides of the first bottom plate layer and the second bottom plate layer. Sealing the deformation joint can ensure safety.
[0011] Furthermore, a lower extension plate is provided on the side of the deformation joint corresponding to the first concrete slab layer, and an upper extension plate is provided on the side of the deformation joint corresponding to the second concrete slab layer. The lower extension plate and the upper extension plate are staggered with each other. The staggered arrangement of the two can further increase the resistance to groundwater penetration, and can increase the waterproof quality and effect.
[0012] Furthermore, a waterproof layer is provided on the top of the T-shaped gusset plate, and the waterproof layer is widely laid on the top of the first bottom plate layer and the second bottom plate layer. An isolation layer is provided on the top of the waterproof layer, and the waterproof layer can further prevent moisture penetration. The entire deformation joint waterproof structure is isolated by the isolation layer, and the isolation layer is used to isolate other building structures above the deformation joint of the underground structure from the deformation joint to prevent interference, etc.
[0013] The waterproof structure of an underground structure deformation joint provided by the embodiment of the present disclosure can achieve the following technical effects:
[0014] 1): In the utility model, two layers of waterproof rolls are arranged between the first bottom plate layer and the first concrete plate layer. The upper layer of the two layers of waterproof rolls is arched upward at the deformation joint, and the lower layer of the waterproof rolls is arched downward at the deformation joint. The two layers of waterproof rolls are enclosed at the deformation joint position to form a space, and the space is filled with foam strips. The foam strips play an elastic supporting role for the two layers of waterproof rolls. When the deformation joint is deformed under the principle of thermal expansion and contraction, the waterproof roll will be stretched, and the arched part of the waterproof roll in the deformation joint can be used as the pulling margin when the deformation joint is deformed, which can effectively prevent the waterproof roll from being torn off during the deformation of the deformation joint, affecting the service life and the waterproof quality of the waterproof structure;
[0015] 2): The arc-shaped bottom pipe in the utility model is made of elastic material, which has tensile strength. The arc-shaped bottom pipe and the waterproof coiled material can fully prevent groundwater from seeping, and both have flexible tensile strength, ensuring sufficient durability, waterproof quality and service life;
