Strong permeable stratum anti-drainage combined basement anti-floating structure and control method

Abstract

The invention belongs to the technical field of basement anti-floating, and discloses a strong permeable stratum anti-drainage combined basement anti-floating structure and a control method. A plurality of anti-floating anchor rods are arranged below a water-resistant plate; a water collecting pit is connected between a basement bottom plate and a basement outer wall, and one end of the water collecting pit is connected with a drainage pipe; and a valve and a pressure gauge are mounted on a pipe section between the drainage pipe and the water collecting pit. Through the arrangement of a filter well, the drainage pipe and the water collecting pit, underground water, exceeding the anti-floating defense water level, at the bottom of the basement can be drained into the water collecting pit, the water head is lowered, and the effect of controlling the water pressure is achieved; through the arrangement of a pervious concrete layer around the filter well, the effects of filtering accumulated water in the basement and preventing the drainage pipe from being blocked can be achieved; and through the arrangement of the water-resistant plate and the anti-floating anchor rods, the normal anti-floating requirement of the basement is met, underground water can be drained in extreme weather, the situation that the underground water level is higher than the designed anti-floating water level is prevented, and therefore the floating problem of a large number of basements is solved.

Description

technical field [0001] The invention belongs to the field of basement anti-floating technology, and in particular relates to a basement anti-floating structure combined with strong water-permeable stratum anti-drainage and a control method. Background technique [0002] At present: With the development of urban construction, urban land is gradually reduced, and the development and utilization of underground space is continuously improved. For shallow basements or deep basements with ground floor buildings, conventional anti-floating piles and other anti-floating piles are required. The floating plan can also be used to solve the anti-floating problem of the basement by using the foundation pit to remove groundwater. [0003] Anti-floating anchor is a kind of anti-floating measures for underground structures in construction projects. It refers to the structural components set up to resist the upward displacement of buildings on it. On the contrary; the anti-floating pile is ...

AI Technical Summary

Problems solved by technology

[0005] Through the above analysis, the existing problems and defects of the existing technology are: in recent years, due to the occurrence of extreme weather or the influence of the surrounding environment, the maximum water level during the service period cannot be predicted, and the groundwater level continues to appear higher than the design anti-floating water level. If the high water level is designed, The cost of anti-floating will rise sharply, and energy saving and emission reduction will not be used
