In the dense area of municipal pipeline, can't apply as the capping beam, utilize underground structure and earthing dead weight to hardly satisfy anti floating requirement. Therefore, in order to develop an underground space and ensure the stability of an underground structure, the combination of the underground continuous wall and the top plate for anti-floating design has important significance.

The existing anti-floating structure for the underground diaphragm wall is complex in structure and does not have the drainage function. Generally, passive anti-floating measures are destroyed at the time of heavy rain in a heavy water season, action time is generally short, once the damage occurs, results are irreversible, people think of actively controlling underground water level according to the characteristics of underground water, and in order to ensure the safety of building structures and save manufacturing cost, in recent years, few building basements adopt active anti-floating measures of a drainage pressure reduction method. The method is characterized in that a hole is formed in the outer wall of the basement to drain water, and the underground water level is controlled at the elevation of the hole. When the basement scope is great, need to open a hole at basement bottom base and sluiced off just can guarantee that groundwater control is below the design water level. As such, the operational cost of use is increased. In view of the above, we propose an underground continuous wall structure with anti-floating measures.
