Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, specifically to a seepage-proof structure for water supply and drainage engineering buildings. Background Technology

[0002] Drainage engineering is an engineering facility system for treating and discharging domestic sewage, industrial wastewater, and precipitation. Its role is to protect water resources, prevent pollution, and safeguard public health and the ecological environment. It covers the entire process of planning, design, construction, and operation management and is a key support for urban water cycle and sustainable development.

[0003] The function of the seepage prevention structure in water supply and drainage engineering is to prevent water or other fluids from seeping in, prevent sewage, groundwater, rainwater, etc. from leaking or intruding, and prevent external water bodies from intruding and affecting the normal operation of the project. For example, it prevents groundwater from seeping into pump rooms, water tanks, etc., affecting equipment safety and water quality, and ensures the stable function of the water supply and drainage system.

[0004] Existing seepage prevention structures for water supply and drainage engineering buildings still have the following problems: it is inconvenient to replace the sealing components, and the sealing components need to be replaced after long-term use. Usually, threaded clamps are required to install the sealing structure, which makes disassembly and replacement troublesome, time-consuming and labor-intensive. In order to address the above problems, a seepage prevention structure for water supply and drainage engineering buildings is proposed. Utility Model Content
