Pit building underground space moisture preventing system

Abstract

The invention belongs to the technical field of buildings, and in particular, relates to a pit building underground space moisture preventing system. The pit building underground space moisture preventing system comprises seepage pipes arranged at the bottom of a pit building at intervals; seepage holes are formed in pipe bodies of the seepage pipes in the pipe length directions at intervals; water outlet ends of the seepage pipes communicate with a water collecting pipe; a water outlet end of the water collecting pipe communicates with a deep well pipe; a deep well pump is arranged in the deep well pipe; a water outlet of the deep well pump is connected with a drainage pipe; and the other end of the drainage pipe extends into a reservoir arranged on the ground. In the pit building underground space moisture preventing system, water in soil of underground space of the pit building flows into the seepage pipes under the effect of self gravity, flows into the deep well pipe by the watercollecting pipe, and is pumped by the deep well pump, so that the dry state of the soil at the bottom of a pit building foundation is guaranteed, and the phenomenon of moisture generation due to seepage of the water into the underground space of the pit building is prevented; and the water in the reservoir can be supplied to construction sites or can be used as life water, so that the water sourceis saved, and the characteristics of small size, economy and applicability are achieved.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a moisture-proof system for the underground space of a deep pit building. Background technique [0002] In recent years, with the rapid development of cities, the height of buildings has become higher and higher. In order to meet the technical requirements of the foundation construction of these buildings, the foundation pits of the foundation have also become deeper and deeper. However, in areas with rich water systems or high groundwater levels in our country, the soil water content is high, and the underground spaces attached to many deep pit buildings fail to meet the technical requirements due to the waterproofing during the construction process. It is in a humid state for a long time, and for places where people stay for a short time or do not go frequently, the ground sometimes grows green moss, especially some underground storage rooms that are often in a hi...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a moisture-proof system for the underground space of deep pit buildings, which can timely remove the moisture in the bottom foundation of the underground space and the soil, and prevent the accumulation of moisture at the bottom of the underground space and cause The problem of moisture resurgence at the bottom of deep pit buildings
