Description

Technical Field

[0001] This invention relates to the field of industrial building construction technology, specifically to an intelligent water-tight and leak-proof process for the construction phase of cleanrooms. Background Technology

[0002] Cleanrooms are core infrastructure for precision manufacturing industries such as semiconductors, biopharmaceuticals, and high-end electronics. Their internal environment has extremely stringent requirements for humidity, cleanliness, and operational reliability. Preventing leakage in the ground and enclosure structure during the construction phase is the primary prerequisite for ensuring future production safety, preventing cross-contamination, and avoiding catastrophic economic losses. The current common practice is to apply a single layer of waterproof coating to the concrete base, use sealant to simply treat joints such as pipe penetrations through walls, and conduct a one-time water tightness test after all decoration is completed to check for leaks.

[0003] This method has the following problems: the water tightness test is the last step, and if there is a leak, the clean floor that has been completed needs to be broken up for repair, which is costly, time-consuming, and the repair process will pollute the clean environment; traditional methods mainly rely on sealant to "plug leaks", which is prone to aging and peeling after long-term use, making it a high-risk area for leakage; the quality of waterproofing depends too much on the skills of workers and materials, and the waterproof layer is easily damaged when different trades are working together, and there is no clear handover of responsibility and protection measures. Therefore, this application proposes an intelligent water tightness and leak prevention process for the construction stage of cleanrooms. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent water-tight and leak-proof process for use in the construction phase of cleanrooms, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent water-tight and leak-proof process for the construction phase of a cleanroom, comprising the following steps: S1. Base treatment and acceptance: The concrete base is treated to control its slope and flatness, and the moisture content of the base is tested with instruments. After it meets the standard, it is accepted. S2. Waterproofing treatment of key nodes using prefabricated construction: For key nodes such as pipes penetrating the floor slab, wall base corners and construction joints, pre-treatment is carried out using sleeves with water-stop wing rings and integrally molded reinforcing components to form a waterproof barrier mainly based on physical structure. S3. Construction of multi-layer composite waterproof layer: On the substrate treated by S1 and S2, a cement-based penetrating crystalline material layer, a flexible adhesive transition layer, and an elastic waterproof surface layer are applied in sequence to form a composite waterproof layer; S4. Layered and phased water tightness test: After S1 is completed, the structural layer water tightness test is carried out. After S3 is completed and all pipelines are installed and before the decorative surface layer is constructed, the waterproof layer water tightness test is carried out. After the decorative surface layer is completed, the system verification water tightness test is carried out. S5. Process handover and process protection: After the completion of the phase node of S3 or S4, process handover shall be carried out, the protection requirements for subsequent construction shall be clarified, and the damage to the waterproof layer caused by subsequent operations shall be supervised and repaired.

[0006] Preferably, in step S1, a laser leveling device is used to control the ground slope. The instrument is a needle-type concrete moisture meter, and the acceptance standard is that the moisture content is not higher than 4%.

[0007] Preferably, in step S2, when installing the sleeve with the water-stop wing ring, the wing ring is located in the middle of the floor slab thickness, and the gap between the sleeve and the hole in the floor slab is filled with micro-expansion concrete.

[0008] Preferably, the elastic waterproof surface layer in step S3 is a two-component polymer-modified cement waterproof coating with a total dry film thickness of not less than 1.5 mm. For areas with corrosive environmental risks, use epoxy resin waterproof coating with a thickness of not less than 2.0 mm.

[0009] Preferably, when applying the elastic waterproof surface layer in step S3, an overlap edge is reserved between adjacent construction units, and additional reinforcement treatment is performed.

[0010] Preferably, the waterproof layer water tightness test in step S4 is a comprehensive test, and it is carried out in a regional manner, with the area of ​​a single test area not exceeding 400 square meters and the water tightness time not less than 48 hours. During the waterproofing layer water tightness test, an infrared thermal imager is used to conduct auxiliary detection on the area below the test area.

[0011] Preferably, during the water tightness test of the waterproof layer in step S4, a colored, harmless tracer is injected into the drain to help determine the sealing performance of the drainage pipe.

[0012] Preferably, the process handover in step S5 includes signing a handover confirmation document and setting up clear protective area markings on site.

[0013] Compared with existing technologies, the beneficial effects of this invention are: by constructing waterproofing treatment at independent and pre-planned nodes, the reliability of the most leak-prone areas is fundamentally enhanced; the multi-layer composite waterproofing performs better than single-layer coatings; it is worth mentioning that the waterproofing layer water tightness test step can detect and repair potential leaks before paving the floor, avoiding rework and losses later; and by using quantitative acceptance and standardized nodes, the reliance on workers' experience can be reduced, further improving construction quality.

[0018] In step S1, a laser leveling device is used to control the ground slope. The instrument is a needle-type concrete moisture meter, and the acceptance standard is that the moisture content is not higher than 4%.

[0019] In step S2, when installing the sleeve with the water-stop wing ring, the wing ring is located in the middle of the floor slab thickness, and the gap between the sleeve and the hole in the floor slab is filled with micro-expansion concrete.

[0020] In step S3, the elastic waterproof surface layer is a two-component polymer-modified cement waterproof coating with a total dry film thickness of not less than 1.5 mm. For areas with corrosive environmental risks, use epoxy resin waterproof coating with a thickness of not less than 2.0 mm.

[0021] In step S3, when applying the elastic waterproof surface layer, an overlap edge is reserved between adjacent construction units, and additional reinforcement treatment is carried out.

[0022] In step S4, the waterproof layer water tightness test is a comprehensive test and is carried out in a regional manner. The area of ​​a single test area is no more than 400 square meters and the water tightness time is no less than 48 hours. During the waterproofing layer water tightness test, an infrared thermal imager is used to conduct auxiliary detection on the area below the test area.

[0027] In a certain factory project, area A uses the process of this invention, while area B uses the traditional process. Application process: In Area A, several potential leaks were discovered and repaired during the second water tightness test before the construction of the decorative surface layer, while in Area B, leaks were only discovered during the final system test after all the decoration was completed. Comparison of results: Area A has low repair costs and does not affect the construction period, while Area B requires damage to the completed ground for repairs, which is costly and delays the construction period by nearly three weeks; The comparison shows that the present invention can detect problems in advance and avoid significant losses.
