Study on key technologies of water-bearing anti floating in construction engineering with strong permeable environment along riverside or coastal area
The structural anti-floating design is the key to ensure the safety of the construction engineering with strong permeable environment along the riverside or coastal area.Based on a construction project along the riverside in Guangzhou,the concept of"water-bearing anti floating"was proposed.In the new water-bearing anti-floating technology,the self-overflow of water level and uniform pressure relief are independently controlled to eliminate partial water buoyancy by dredging the stratum seepage,discharging water from the pipe hole,and so on,and beneficial loads are fully utilized to resist the excess part of the water buoyancy.The water-bearing anti floating system with multiple functions such as groundwater dredging,drainage and observation was built.The construction steps,key points,problems needing proper treatment,operation and maintenance requirements of water-bearing anti floating system were introduced in detail.The results show that the new technology of water-bearing anti floating has obvious indigenous advantages such as low cost,short construction period,small environmental impact,and convenient construction.The problem of high cost,long construction period and poor durability that the traditional anti-floating technology is used in the construction project with strong permeable environment along the riverside is solved,so as to maximize the realization the goal of relying on the structure itself to resist groundwater buoyancy and achieve the balance of economy and security.After verification,the new anti-floating technology can be popularized to the design of similar construction engineering with strong permeable environment along the riverside or coastal area.
