Example 3
The present embodiment provides an anti-floating structure and a construction method, which includes most aspects of embodiment 1, except that when q is 1, the small region is a square. When m × n is an odd number, m × n small regions having the same size and arranged in a matrix form a rectangular anti-floating region.
The invention has the technical effects that on the premise of fully exerting the anti-floating self-balancing capacity of the anti-floating piles, the anti-floating position is selected to reduce the number of the anti-floating piles arranged on the lower surface of the bottom plate and enable the anti-floating piles to be uniformly and symmetrically arranged on the lower surface of the bottom plate, so that the anti-floating structure ensures the anti-floating capacity of the bottom plate and improves the utilization rate of the anti-floating piles. Compare with traditional anti structure of floating, the anti structure of floating of this embodiment can reduce the arrangement of reinforcement of bottom plate and anti stake when anti stake quantity is the same to reduce engineering cost, energy-concerving and environment-protective.
The anti-floating structure and the construction method thereof provided by the embodiment of the application are described in detail, a specific example is applied in the description to explain the principle and the implementation mode of the application, and the description of the embodiment is only used for helping to understand the technical scheme and the core idea of the application; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure as defined by the appended claims.
