[0020] This waterproofing method for underground logistics trenches in electronics factories mainly includes the selection of construction joint locations, the overlap width of waterproof membrane, and the design of waterproof treatment at the construction joint interface. The design needs to consider safety, economy, and feasibility.

[0021] The following is a design for a waterproofing method for underground logistics trenches in electronics factories:

[0022] 1. Location selection:

[0023] Location conditions: Select an area with good foundation bearing capacity and a low groundwater level.

[0024] Load impact: Avoid being below the ground load-bearing area.

[0025] Pipeline integration: Avoid intersections with other underground pipelines.

[0026] Environmental impact: Consider the impact on the surrounding environment when excavating the new pipe trench.

[0027] The location of the construction joint at the junction of the old and new pipe trenches should take into account the load-bearing requirements of the corresponding area of ​​the ground. The location should be chosen as much as possible where the groundwater level is low and construction is convenient. Generally, it should be located under the green belt or sidewalk.

[0028] 2.

[0029] 3. Waterproofing treatment at construction joint interfaces:

[0030] After the concrete interface of the existing logistics pipeline trench is cleaned by grinding, a concrete interface agent is applied. Three shallow grooves with a width of 20mm are cut into the concrete structure interface of the existing logistics pipeline trench. Water-swellable waterstop strips are installed in the shallow grooves, and a 15mm thick 1:1.5 water-emulsion polymer cement mortar bonding layer is applied.

[0034] Environmental friendliness: Materials that comply with relevant standards and specifications are used.

[0035] Safety: The construction operation is of moderate difficulty and the construction process is safe.

[0036] In summary, the design of waterproofing methods for new and existing underground logistics trenches in electronics factories requires comprehensive consideration of multiple factors. From location selection, the overlap width and method of waterproof membrane, to the waterproofing treatment of construction joint interfaces, careful design and meticulous construction are necessary to ensure the efficient operation of the underground trenches.

Water-swellable waterstop strips 7 are installed in the shallow grooves, and a concrete interface agent and a 15mm thick 1:1.5 water-emulsion polymer cement mortar bonding layer 4 are applied to the construction joint 5.

[0044] Acceptance criteria: No damp stains, no leakage.

[0045] Construction monitoring: During construction, the existing waterproofing layer of the underground logistics trench must be protected in real time to ensure its integrity. Any abnormalities, such as overstretching or damage, must be identified and addressed promptly.

[0046] Environmental protection: Take effective measures to reduce the impact of construction sites on the surrounding environment, such as noise and dust control.
