Silicon lime sand water guiding, draining and filtering multifunctional rapid and rigid congealing body manual repaired foundation pit water-stopping curtain

Abstract

The invention discloses a silicon lime sand water guiding, draining and filtering multifunctional rapid and rigid congealing body manual repaired foundation pit water-stopping curtain which comprises an overall single-row closed water-stopping curtain body arranged on the inner side wall of a foundation pit, wherein the overall single-row closed water-stopping curtain body is formed in the mode that adjacent reinforced concrete support piles are connected in a lap joint mode through primary-secondary curtain piles. The silicon lime sand water guiding, draining and filtering multifunctional rapid and rigid congealing body manual repaired foundation pit water-stopping curtain further comprises multifunctional rapid and rigid congealing bodies which are located below the underground water level and integrally formed by steel chisels, water permeable filter layers, macadam filter material layers, silicon lime sand isolating layers and silicon lime sand layers, the primary-secondary curtain piles and the reinforced concrete support piles or every two adjacent primary-secondary curtain piles are connected into a whole through the multifunctional rapid and rigid congealing bodies, and water guiding pipes are inserted in the macadam filter material layers. The silicon lime sand water guiding, draining and filtering multifunctional rapid and rigid congealing body manual repaired foundation pit water-stopping curtain has the water drainage pressure reducing function, further has the functions of water stopping, water drainage, water reduction, water filtering, soil conservation, sand fixing and the like, and is easy and convenient to use, practical and economical, and cost is saved; the quality of the curtain is guaranteed, the water stopping effect of the water-stopping curtain is guaranteed, and the project construction cost is reduced.

Description

technical field [0001] The patent of the invention belongs to the technical field of civil engineering groundwater anti-seepage structure design, and particularly relates to the development of underground mineral resources, the development of underground space resources, and the anti-seepage of buildings, etc. design. The patent of the present invention is suitable for emergency and surprise use in the case of sporadic water-stop curtain water-stop failure, the workload is not large and the MGJ-50 drilling rig is lacking. Background technique [0002] With the continuous increase of high-rise buildings, it is not uncommon to use well point precipitation in the construction of old urban areas, causing cracks and sinking of adjacent buildings, pipelines, and road surfaces. In order to protect groundwater resources, reduce waste, and prevent related geological disasters caused by groundwater level drop outside the foundation pit, it will cause various hazards to surrounding bu...

Problems solved by technology

[0005] The disadvantage of the ZL201320070818.1 "Foundation Pit Waterproof Curtain for Secondary Melting of Infiltration and Impregnation Agglomerates" is that the auxiliary small piles occupy the space of the fertilizer tank and have redundant functions, which increases the cost; the filling of the auxiliary small piles The penetration and impregnation bonding body between the supporting piles or the gap between the small piles and the cement-soil curtain piles are redundant functions and increase the production cost and material cost
