Ground structure with underground space having drainage and seepage functionand construction method thereof

Abstract

The invention discloses a ground structure with an underground space having drainage and seepage functionand a construction method thereof. A pad layer, a base board, drainage plates and a reinforcedconcrete layer are paved from bottom to top for ground pavement. A plurality of drainage ditches are formed in each independent ground area along the edge of the area, drainage ditches in the same area are mutually connected and are connected into a nearest water collection well. Each drainage plate comprises a water separation main body and a plurality of hollow protrusions integrally formed withthe water separation main body. The drainage plates keep in communication with the corresponding drainage ditches in the same area.Water stop devices are arranged between the base board and the concrete layer along the edges, where no drainage ditches are arranged, in each areaand the water stop devices communicate with the drainage plates in the same area. In order to solve the problem of the waterproof failure of the original floor paving, an effective scheme which thoroughly solves the surface water seepage problem in underground space is provided, and meanwhile, the invasion to walls, ramps or the bottoms of steps in the areas without drainage ditches by water seepage is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of water drainage in construction engineering, and in particular relates to a ground structure capable of water drainage in an underground space and a construction method thereof. Background technique [0002] With the development of society, human beings expand and develop underground spaces more and more widely and frequently, such as basements, underground parking lots, underground shopping malls and so on. In the development of related construction projects, the owner often has higher and higher requirements for construction quality, especially for related waterproof requirements. In actual underground engineering construction, due to geological structure, improper construction and maintenance methods, fluctuations in the quality of raw materials, temperature, shrinkage, etc., cracks will appear on the floor that has been waterproofed. Moreover, the bottom plate cracks are often unavoidable, which in tu...

Problems solved by technology

Usually the method of plugging is almost difficult to solve the problem fundamentally, and the use of gravel hydrophobic layer has strict and more complicated requirements for related construction, and the problem of cost is also very prominent
