Dewatering and drainage mechanism

Abstract

The invention discloses a dewatering and drainage mechanism which comprises a drainage plate, wherein one side of the drainage plate is embedded in a protective wall; the protective wall is connected with the drainage plate through a tension spring; a water seepage tube is vertically installed in the protective wall; the bottom of the protective wall is arranged on a cushion layer; the cushion layer is fixedly connected with the protective wall through a concrete mortar layer; one side of the cushion layer is arranged on a drainage through tube; the drainage through tube penetrates through the cushion layer; a water filtering plate is arranged in the cushion layer; a tube well is formed in the upper surface of the water filtering plate and is communicated with the water filtering plate; an opening is formed in the upper part of the tube well; a drainage tube is vertically formed on the upper surface of the water filtering plate and on the outer side surface of the tube well; and the bottom of the drainage tube extends into the cushion layer. The dewatering and drainage mechanism can well put an end to the swelling phenomenon in the concrete initial setting process, can effectively lowers the influence of underground water on a bottom plate of a basement to zero, can also effectively drain water within a range of a deep foundation pit, can meet the requirement for self waterproofness, can ensure the quality of subsequent construction and ensures subsequent construction not be influenced by water seepage.

Description

technical field [0001] The invention relates to a municipal road facility, in particular to a drainage mechanism. Background technique [0002] Excavation of foundation pit is an important construction procedure of modern large-scale buildings. In the construction of foundation pit engineering, it is necessary to control the groundwater level in the foundation pit to meet the requirements of supporting structure and excavation construction. Generally, during the excavation process, a large amount of groundwater needs to be drained, and in order to reduce the adverse effects of the groundwater level drop around the foundation pit on the original buildings near the foundation pit, such as uneven settlement, it is necessary Recharge measures are taken between buildings to resist large-scale precipitation, but the general drainage mechanism has great defects in function and cannot better meet the needs of use. Contents of the invention [0003] The technical problem to be so...
