the third step is to install the water collection tank 7, put the water collection tank 7 into the groove through the hoisting device, sleeve the lock nut 805 outside the cylindrical barrels 803, because the opening of the clamping barrel 714 is large when the lock nut 805 is not installed, the cylindrical barrels 803 can be smoothly inserted into the clamping barrel 714 and enter the connecting box 701, after the cylindrical barrels 803 are clamped in the clamping barrel 714 by tightening the lock nut 805, and after each cylindrical barrel 803 is inserted and installed, the water collection tank 7 is connected with the pipe pile assembly 6;

Finally, after the four-side water collection tank 7 is installed, a reinforcing steel bar frame is placed on one inclined side surface of the water collection tank 7, and the concrete template 4 is built, so that the bottom can bear larger lateral force by casting concrete on the side wall to form a right trapezoid cross section, meanwhile, the use of concrete on the top is reduced, and the construction cost is reduced while the side wall of a foundation pit is well reinforced;

When the soil is specifically impermeable, because the groundwater in the outer soil layer 1 is mixed with the soil, the humidity of the outer soil layer 1 is high, a space exists in the hexagonal cylinder 801, and the permeable circular membrane 802 and the permeable long membrane 804 can be made of non-woven fabrics or cotton cloth flax with good permeability, so that the permeability of the permeable circular membrane 802 and the permeable long membrane 804 in the soil is ensured, the moisture in the outer soil layer 1 and the hardened soil layer 2 can easily enter the hexagonal cylinder 801 through the permeable circular membrane 802, and the water is stored in the water collection tank 7 through the inclined connecting anchor rod 8;

Because the hardened soil layer 2 is in direct contact with the outer soil layer 1, although the water content in the hardened soil layer 2 is lower than the water content in the outer soil layer 1, the penetration of underground water into the hardened soil layer 2 cannot be completely blocked, and the water in the hardened soil layer 2 enters the connecting anchor rod 8 in the same manner and principle, so that the water content in the hardened soil layer 2 is reduced;

After the water content is reduced by the hardened soil layer 2, the pipe pile assembly 6 further blocks the groundwater, the first sealing member 612 and the second sealing member 617 are sealed, and as shown in fig. 16, the outer parts of the first sealing member 612 and the second sealing member 617 are both elastic outer layers 618, and water can penetrate into the inside through the water permeable holes 619, wherein the water absorbing expansion body 621 can be a water absorbing expansion solid such as water absorbing resin, and the volume of the first sealing member 612 and the second sealing member 617 is increased by utilizing the water absorbing expansion of the water absorbing expansion body 621, so that the tightness of the pipe pile assembly 6 is improved;

Even if a small amount of moisture permeates into the concrete layer 3 from a position where the tubular pile assembly 6 is not sealed, since the water collecting tank 7 is arranged in the middle of the concrete layer 3, the water collecting tank 7 can be made of light water-blocking materials such as alloy or plastic, so that the moisture of the concrete layer 3 can be prevented from directly permeating into a foundation pit, and since the water collecting tank 7 is arranged on a side wall close to the tubular pile assembly 6 and is arranged on a diagonal line between the upper, lower, left and right clamping cylinders 714, the moisture in the concrete layer 3 can be guided to the vicinity of the cylindrical cylinder 803 no matter which direction permeates up, down, left and right, so that the moisture content near the cylindrical cylinder 803 is the highest, thereby facilitating the moisture to enter the cylindrical cylinder 803 to be collected and reducing the moisture content in the concrete layer 3;

When water enters the connecting anchor rod 8 through infiltration, because the connecting anchor rod 8 is arranged in a downward inclined mode, the cylindrical drum 803 inserted into one end of the clamping drum 714 is lower, water penetrating into the connecting anchor rod 8 through the permeable circular membrane 802 and the permeable long membrane 804 flows into the connecting box 701 as soon as possible, the accumulated water is drained downwards through the guide cotton wire 702 at the bottom of the connecting box 701, accumulation of the accumulated water is finally carried out in the water storage tank 703, when the stored water is enough, the water level switch 712 controls the water control valve 711 to be opened, water enters the inside of the water draining piece 706, the pressure of the top water can enable water to be injected into the jacking water bag 710 through the hose 708, as shown in fig. 11 and 12, the jacking water bag 710 in the water bag 709 jacks one side of the water receiving plate 705, an inclined plane convenient for slowing down water impact is formed, the direct impact of the water flow and the caused vibration are prevented from damaging the water collection tank 7 and the concrete layer 3, the water level switch controls the water control valve 711 to be closed when the stored water is enough, the stored water is gradually reduced, the pressure of the water level switch 712 enables the water in the jacking water collection plate 710 to be gradually reduced, the water collection plate 705 is gradually reduced, the water is pumped from the water collection tank 5 to the bottom surface 5 is gradually, and the water is finally pumped from the water collection tank 5 to the bottom surface 5 through the water collection plate 5, and the water collection plate 705 is gradually pulled up along with the water level layer 3, and the water is drained from the water tank 3.
