Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to an anti-leakage type water dispersion structure. Background Art

[0002] Due to the demand for clean energy transmission channels, the construction of new energy in the Haixi region has grown rapidly, and many new collection stations and substations have been built in the region. Usually, there is no requirement for anti-seepage in the design of substation scattered water, and no water-proof measures are set. Most of the soil in the Haixi region is saline soil. Under normal conditions, saline soil is cemented in the soil, and its hardness is high and it is in a compressed state. However, when saline soil meets water, the salt content in the soil accounts for a large proportion, and the soluble salt in the foundation soil is easily dissolved, the overall strength of the soil is destroyed, the structural characteristics of the soil are changed, and the bearing capacity of the foundation drops sharply, making it difficult to use it as a foundation for engineering construction. If the soil under the scattered water dissolves and loses, the scattered water will tilt toward the side of the building. In rainy weather, rainwater will flow back into the building, affecting the safety of the building.

[0003] The utility model effectively isolates rainwater from seeping into the station area by hot-melting and pasting SBS waterproof membrane on the concrete surface layer and the outer side of the wall, prevents the soil at the bottom of the scattered water from being lost when encountering water, and effectively ensures the safety of the building through vertical drainage within the site, thereby improving the safe and stable operation of the substation.
