Embodiment Construction

[0037] like figure 1 and figure 2 As shown, the high underground water level region of the present invention is adjacent to both a building preventionally conjunction with a wall collapsed, and the high underground water level region is adjacent to both a building prevention, and the wall collapsed structure is prevented. The high-ground water level region adjacent to the existing building prevention of the wall collapsed structure includes a retaining wall 12 on the surface 14 of the existing building base 11 to be applied to the ground 14, the building base layer 11 and the retaining wall 12 There is a filling layer 13, the top elevation of the filling layer 13 is lower than the height of the groundwater level 10, and the height of the underground water level 10 is lower than the top elevation of both the construction ground 15, and the construction 1 is constructed on the building layer 11, The groove wall reinforcing body 5 sequentially passes through the filling layer 13 and ...

Abstract

The invention discloses a method for preventing ground wall collapse in a high groundwater level area adjacent to an existing building. Solid; 4. Construction foundation guide wall; 5. Construction expansion guide wall. The invention aims at constructing the underground diaphragm wall beside the local high groundwater level area where the existing building is constructed, and the situation that the precipitation outside the tank wall cannot be carried out. For support, pre-embedded stubble bars are reserved at the edge of the foundation guide wall to connect the expansion guide wall. There is a height difference between the expansion guide wall and the groundwater level to balance the pressure difference between the inner and outer water heads of the tank wall, enhance the stability of the tank wall, prevent the tank wall from collapsing, and ensure construction Safety.

Description

Technical field [0001] The present invention belongs to the field of prevention, and in particular, the present invention relates to a method of highly underground water casing regions adjacent to both construction prevention and land collapse. Background technique [0002] In recent years, with the acceleration of urbanization, the field of foundation pit excavation applications is broader, and the geological conditions faced are more complicated. As the support structure of the foundation pit, the underground continuous wall can not only effectively undertake the side-to-earth pressure, but also have a good waterproof effect, and the role of the water curtain, so many deep basis pit projects use the underground continuous wall as a sergeant structure. [0003] The underground continuous wall is prone to the imbalance, collapse of the groove, collapse, etc. during the groove, which affects construction safety. Among them, the construction method of underground continuous wall as...
