In this example, a pipe joint 8d for connecting the gas-permeable observation pipe 18 is provided on the top of the groove, a plurality of second reinforcing ribs 8e are provided between the outer surface of the pipe joint 8d and the outer surface of the top of the groove at intervals in the circumferential direction of the pipe joint 8d, and the plurality of second reinforcing ribs 8e are uniformly distributed in the circumferential direction of the pipe joint 8 d. The arrangement of the pipe connector 8d not only enables air inside the water collecting tank to circulate, so that water drainage is smoother, the water drainage effect is good, but also connection of the external breathable observation pipe 18 is facilitated.
The structure of the drain plate 7 used in the drain unit in this embodiment is as shown in fig. 6 to 7, and includes a base plate 7a and a plurality of bosses 7b arranged on one side surface of the base plate 7a at intervals, wherein the plurality of bosses 7b are arranged in a matrix on the base plate 7a, and drain passages are formed between two adjacent bosses 7b, and all the drain passages are communicated with each other.
The top surface of each boss 7b is sunken inwards to form a groove 7c, and the grooves 7c can store water in actual use; the side surface of each boss 7b is provided with a plurality of reinforcing ribs 7d along the circumferential direction of the boss 7b, and each reinforcing rib 7d is provided to extend from the top surface of the boss 7b to the base plate 7 a. The provision of the reinforcing ribs 7d helps to increase the compressive strength of each boss 7b, thereby giving the entire drain board a better compressive strength.
2-10 reinforcing ribs 7d are uniformly distributed on each boss 7b along the circumferential direction, in this example, 6 reinforcing ribs are provided; each reinforcing rib 7d is formed by a side surface of the boss 7b being depressed inward.
In this example, the boss 7b is a hollow circular truncated cone formed by recessing one side surface of the substrate 7a toward the other side surface, and the area of the top surface of the boss 7b is smaller than the area of the bottom surface of the boss 7 b.
The drain board 7 also has an anti-collapse function, and specifically, a convex part 7e for preventing collapse is arranged on the base board 7a between two adjacent bosses 7b, and the height of the convex part 7e on the base board 7a is smaller than that of the bosses 7b on the base board 7 a. In this example, the base plate 7a between two adjacent bosses 7b is provided with a projection 7e in the longitudinal extending direction or the width extending direction of the drain plate.
In this example, the protrusion 7e is formed by recessing one side surface of the substrate 7a toward the other side surface, and the substrate 7a, the boss 7b and the protrusion 7e are integrally molded, and are made of a polymer material, such as HDPE.
Use the drain bar 7 and the cooperation of water catch bowl 8 of this embodiment, lay the closed frame that encloses that comprises a plurality of water catch bowl 8 after planning the bullet line according to the construction process, as referring to fig. 3, water catch bowl 8 lays and lays drain bar 7 in the closed frame that encloses after finishing, water catch bowl 8 cross the water hole 8c set up make when drain bar 7 and water catch bowl 8 lay the completion back, make water catch bowl 8 cross the water hole 8c the size and with the continuous drain bar 7's of water catch bowl 8 highly suit, avoid the water hole of crossing of water catch bowl 8 among the prior art influence that the intensity of water catch bowl 8 brought excessively. In addition, in this embodiment, 4 water holes 8c are provided between two adjacent first reinforcing ribs 8b, so as to improve the water passing effect of the water collecting tank 8 and effectively discharge the permeated water on the drainage plate 7. Simultaneously first strengthening rib 8 b's evenly distributed for 8 whole compressive capacity of water catch bowl are higher, and then improve the security and the service life of planting roof sponge city zero slope and organizing siphon drainage collection system. The arrangement of the pipe connector 8e not only enables air inside the water collecting tank 8 to circulate, so that water drainage is smoother, the water drainage effect is good, but also facilitates the connection of the external breathable observation pipe 18. And the drain bar 7 adopts the drain bar of preventing collapsing, and whole compressive strength is high, receives can not sink after earthing pressure to the setting of bellying 7e even if the setting of collapsing still has certain drainage space and ensures that the rainwater can be orderly discharges. In addition, the groove 7c of the drainage plate 7 ensures the water storage effect and capacity of the drainage plate 7c, and the infiltrated water is upwards discharged, so that the drainage channel is a good vertical channel for soft foundation treatment of saturated viscosity and miscellaneous filling such as silt, mucky soil, filling soil and the like by using a drainage consolidation method, and the soft soil consolidation time is greatly shortened.
Meanwhile, the siphon drainage collection system of the embodiment also has the following advantages:
(1) the unit of catchmenting lays around the building roof, and the water drainage tank no longer arranges in the roof intermediate position, and the drain bar has the function of preventing collapsing and makes the drain unit be the drainage surface of a intercommunication, and the cooperation side drainage rainwater fill makes the system form the full current at the straight tube section of siphon more easily, and the emission of infiltration water on the drain bar accelerates, and the quantity of addding the side drainage rainwater fill promotes the water discharge capacity simultaneously. And on the other hand, the middle position is not provided with a water collecting tank, so that the using amount of the water collecting tank is reduced in principle, the construction period is shortened on the basis of the existing system, and the manufacturing cost is reduced.
(2) The siphon adopts the mode that eccentric reducing is connected with the straight tube section, forms better water conservancy operating mode, further accelerates the full pipe of siphon to further promote drainage speed.
(3) The water discharged into the settling well by the siphon is firstly settled and then enters the reclaimed water module after overflowing through the partition plate, the quality of reclaimed water is improved, meanwhile, the reclaimed water module also reclaims rainwater on the roof of the community floor, the reclaimed water can be used for irrigating plants on the vegetation layer, the reutilization of rainwater resources of the community is realized, and the water resource is saved.
