6. The communicating vessel type tool type anti-floating treatment pressure relief device as claimed in claim 1, wherein a steel disc is fixed on the outer circumference of the conduit, and the steel disc is fixed with the inner bottom surface of the water collecting well through chemical bolts.
7. The connector-type tool-type anti-floating treatment pressure relief device as claimed in claim 1, wherein the conduit and the U-shaped pipe are fixed to the wall of the basement by steel hoops.
8. A method of pressure relief, based on the pressure relief device according to any of claims 1-7, comprising the steps of:
(1) rechecking the anti-floating water level of the basement;
(2) observing the pressure relief water yield of the emergency pressure relief hole under the condition of extreme rainstorm, counting the actual highest water level of the building, and accounting the quantity and distribution requirements of the required conduits for pressure relief;
(3) modifying an original design water collecting well or modifying a newly-added water collecting well on a bottom plate, reserving a guide pipe with the diameter of 150mm at the bottom of the well, arranging a water collecting pipe for filtering at the bottom end port of the guide pipe, digging a filtering pit around the water collecting pipe, wherein the distance between the bottom of the filtering pit and the bottom of the water collecting pipe is more than 300mm, paving stones along the pit wall in the filtering pit, and filling the filtering pit with coarse sand;
(4) a three-way joint and a U-shaped pipe are arranged at the port at the top end of the guide pipe, the height position of the highest position of the U-shaped pipe is arranged according to the anti-floating water-proof level of the basement, and the guide pipe and the U-shaped pipe are fixed on the adjacent wall body by using a steel hoop;
(5) placing a soft water inlet pipe of a temporary water pump in a conduit, starting the temporary water pump to drain water, and then pouring the conduit into concrete at the bottom of a water collecting well;
(6) after the concrete reaches the strength, fixing the guide pipe at the bottom of the water collecting well by adopting a steel disc and a chemical bolt;
(7) the rest interface of the three-way joint is tightly plugged by a flange plate, a rubber pad and a bolt;
(8) the bottom of the water collecting well is provided with an automatic draining pump.
