Description

Technical Field

[0001] The utility model discloses a mud paste underground engineering anti-seepage and leakage plugging structure, which relates to the technical field of underground engineering waterproof structures, and in particular to a structure using mud paste to carry out anti-seepage and leakage plugging for basements, tunnels, garages, artificial rivers and lakes. Background Art

[0002] Underground engineering waterproofing refers to underground waterproofing projects for industrial and civil buildings. Underground waterproofing projects are a systematic project, which involves various aspects of building management such as engineering waterproofing materials, waterproofing node design, and waterproofing construction. Its purpose is to ensure that the building is not eroded by water, the internal space is not harmed, and to improve the use function and life of the building. With the development of the times and the advancement of science and technology, underground projects have gradually increased. For this reason, underground waterproofing is an important project of underground engineering. The quality of its waterproofing technology will directly affect the use function and service life. However, in the past ten years, according to the comparison of unit projects, the leakage of basements and underground garage roof projects can reach more than 60% to varying degrees. The main reason is that the current waterproofing materials are not suitable and unreasonable for building structures. Due to the leakage, the corrosion of underground engineering structures is also huge.

[0003] There are many kinds of waterproof materials for underground projects, which can be divided into two types of roll materials according to their main raw materials: 1. Asphalt waterproof materials. Asphalt felt, paper-based asphalt felt, etc. are made with natural asphalt, petroleum asphalt and coal tar as the main raw materials. 2. Bentonite waterproof blankets can be divided into needle-punched sodium-based bentonite waterproof blankets, needle-punched film-coated sodium-based bentonite waterproof blankets and adhesive sodium-based bentonite waterproof blankets according to the production process.

[0004] Bentonite waterproof blanket is a geosynthetic material specially used for anti-seepage in artificial lake waterscape, landfill, underground garage, roof garden, pool, oil depot and chemical storage yard. It is composed of highly expansive sodium-based bentonite filled between special composite geotextile and non-woven fabric. The bentonite anti-seepage mat made by needle punching can form many small fiber spaces, so that the bentonite particles cannot flow in one direction. When encountering water, a uniform and high-density colloidal waterproof layer is formed in the mat, which effectively prevents water leakage.

[0005] The mineralogical name of bentonite is montmorillonite. Natural bentonite is mainly divided into two categories according to its chemical composition: sodium-based and calcium-based. Bentonite has the characteristic of swelling when it comes into contact with water. Generally, when bentonite swells, its swelling is about 1-2.5 times, and when it swells, it swells more than 2-15 times. Locking the bentonite between two layers of geosynthetics plays a role of protection and reinforcement, so that the bentonite blanket has a certain overall shear strength. Most of its underground membrane waterproofing technology applications are to set a membrane waterproofing layer on the water surface of buildings and structures, and add a protective layer outside the waterproofing layer. Due to the structure of the membrane itself, it cannot meet the waterproofing requirements of existing buildings, resulting in the following problems in the existing waterproofing construction technology:

[0006] 1. Because the underground engineering structural base does not meet the technical requirements of the waterproofing membrane, it is estimated that the waterproofing purpose cannot be achieved, causing most of the underground waterproofing membranes to be separated from the base and hollow, resulting in engineering leakage;

[0007] 2. The quality life of the waterproofing material itself (15-20 years) is too different from the main body life (generally 100 years);

[0008] 3. Due to the phenomenon of underground waterproof engineering membrane and base layer being separated from the base layer, water leakage occurs in the later maintenance and plugging, which causes great difficulties;

[0009] 4. The coiled material is not suitable for frost heave in cold areas within a certain range of the earth. Because the coiled material is integrated with the frozen soil after freezing in the frozen soil range, the coiled material loses its elongation index. When the frozen soil produces frost heave deformation, the coiled material will inevitably break and leak.

[0010] 5. Currently, bentonite blanket is used for anti-seepage projects. Bentonite blanket is a bentonite anti-seepage roll made of high-swelling sodium-based bentonite filled between special composite geotextile and non-woven fabric by needle punching. Its disadvantage is that the non-woven fabric isolates the bentonite from the structural base layer. The non-woven fabric itself is a permeable material, so it forms a seepage and water-penetrating layer, which leads to leakage.

[0011] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new type of mud paste underground engineering anti-seepage and leakage plugging structure to overcome the problems existing in the prior art. Summary of the invention

[0079] Compared with the prior art, the utility model has the following advantages:

[0080] 1. The utility model provides a mud paste underground engineering anti-seepage plugging structure. A carbon fiber grid is laid on the mud paste waterproof layer. Its purpose is to support the 30-thick cement mortar protective layer and to absorb the mud paste and underground structures. When the mud paste meets water, it has a 10-28 times expansion capacity. At the same time, the mud paste is permanently produced and absorbed by the structure, completely solving the problem of the anti-seepage layer and the object being separated. Due to the flexibility of the mud paste, even if the structure vibrates and settles, the mud paste can repair the cracks on the surface within 20mm;

[0081] 2. The mud paste underground engineering anti-seepage plugging structure provided by the utility model is obtained through more than 20 years of experience in plugging leaks. It has been verified that there has been no reverse repair phenomenon for many years. It mainly adopts natural bentonite non-aging flexible material. According to the material characteristics, the bentonite mud paste is combined with the underground engineering structure and construction to adopt different degrees of technology to achieve the construction simplicity, which is not affected by the environment and temperature, and can self-heal when there are slight cracks in the structure due to various factors. At the same time, it always permanently guarantees the overall effect of the underground waterproof layer and can completely solve the leakage problem of underground engineering. At the same time, it creates favorable conditions for the future maintenance of underground engineering;

[0082] 3. The mud paste underground engineering anti-seepage and plugging structure provided by the utility model fully utilizes the advantages of bentonite materials and can fully achieve the integrity of the waterproof layer. In particular, based on the advantage of the material's strong adsorption, it can completely solve the waterproof leakage problems of various pile head nodes. This material is a flexible material and can achieve self-adjustment for slight structural deformation. When the material encounters water, it expands itself and forms a highly integral plastic waterproof layer within a certain period of time;

[0083] 4. The anti-seepage and plugging structure of the underground mud-paste engineering provided by the utility model has a long waterproof life: because bentonite is a natural inorganic material, it will not age or corrode even after a long time or when the surrounding environment changes, so the waterproof performance can last for more than hundreds of years;

[0084] 5. The anti-seepage and plugging structure of the mud paste underground engineering provided by the utility model is convenient for later maintenance. During the use of the construction project, drilling and reconstruction are not excluded. Since this waterproof technology does not have the hidden danger of water leakage, the cause and surface of the water seepage are clear. In addition, this material is a flexible material, and the combination of new and old materials is not required, which undoubtedly achieves the purpose of simple maintenance;

[0085] 6. The mud paste underground engineering anti-seepage and leak-proofing structure provided by the utility model adopts natural bentonite mud paste anti-seepage technology. The underground engineering structure anti-seepage technology of the utility model has the function of never aging.

[0086] In summary, the technical solution of the utility model solves the problem that the technical conditions of the underground engineering structure base in the existing waterproofing technology do not meet the bonding requirements of the waterproof membrane, resulting in detachment, water seepage, leakage, short service life of building materials, difficulty in later maintenance, freezing deformation and breakage of the membrane in cold areas, and water seepage caused by the non-woven fabric layer dividing the bearing layer.

For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0107] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0115] This embodiment is applied to an underground independent foundation. In the implementation design, since the independent foundation belongs to the bearing relationship between the independent foundation and the earth, the natural stone bearing blocks in the mud paste anti-seepage layer and the reinforced concrete bearing cushion layer under the mud paste need to be designed separately.

[0123] This embodiment is applied to the anti-seepage structure of embodiment 1 which is not suitable for various conditions.
