Detailed Description
The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and it will be apparent to those skilled in the art that various changes may be made without departing from the spirit and scope of the invention as defined and defined in the appended claims, and all matters produced by the invention using the inventive concept are protected.
Examples
Referring to fig. 1, the invention provides a sponge urban overflow facility construction method based on a 3D printing technology, which includes the following steps:
s1, quantifying overflow amount of different overflow facilities in a sponge city by adopting an overflow amount calculation formula;
s2, designing and customizing an overflow facility by utilizing 3D modeling based on an overflow quantity quantification result;
s3, manufacturing a designed overflow facility based on 3D printing;
and S4, replacing the traditional overflow gully and overflow gully well of the sponge city with the overflow facility.
Specifically, in step S1, the overflow amount of the overflow facility is calculated by using a wide top weir formula and an orifice outflow formula. The step S1 specifically comprises the following steps:
s1-1, according to a wide top weir formula:
Qweir＝B·CwL·h 3/2
acquiring the flow Qweir of the overflow catch basin; wherein B is the plugging coefficient; cw is the weir flow coefficient; l is the weir length; h is the water depth;
s1-2, according to an orifice outflow formula:
Qoriice＝B·CdA·(2gh) 1/2
acquiring flow Qorifice when an overflow gutter inlet is submerged; wherein Cd is the drainage coefficient; and a is the orifice area.
In step S2, overflow facilities with different forms of three-dimensional data are designed through a virtual three-dimensional space by using three-dimensional manufacturing software.
In step S3, an overflow facility is manufactured by using an adhesive material in a layer-by-layer printing manner based on the digital model file.
In this embodiment, the overflow amount of the overflow ball is as follows, and the parameters of the overflow ball and the overflow ball sculpture are as shown in fig. 2 to 3.
| 500 overflow ball | 400 overflow ball | |
| Overflow volume (m) 3 /s) | 76.81 | 64.99 |
Further, an overflow facility designed based on 3D printing manufacturing is shown in fig. 4, an overflow sculpture combination is arranged around the initial rain overflow bank of the road surface is shown in fig. 5, parameters of the three sculptures are shown in fig. 2, and spherical openings and intervals of the three sculptures are different. As shown in fig. 6, the overflow ball near the road surface is arranged relatively large, the spherical opening of the overflow ball is also relatively high away from the ground, the remaining water which does not flow into the large overflow ball bypasses the two sides of the overflow ball and flows to the two outer overflow balls, and the other two overflows are relatively small, so that the water which needs to flow in is relatively small. The distribution can not only balance the flow of each overflow ball, but also ensure that the water receiving surface of the garden is larger, the water distribution is more uniform, and the problem of local water accumulation and waterlogging is reduced.
Due to the construction requirements of sponge cities, more and more overflow facilities are built in the cities, and the attractiveness of the overflow facilities is gradually paid attention. The overflow facility construction method provided by the invention gives full play to the advantages of the 3D printing technology, and the sponge city overflow facilities are fully designed and customized through reasonable overflow facility distribution. The method overcomes the defects of unattractive appearance and easy blockage of the traditional sponge overflow facility, realizes the intersection of the 3D printing technology and the urban hydrology field, and reasonably plans the layout of the overflow facility through the calculation of the overflow amount to reduce the influence of flood water. In addition, the method has universality and can be implemented in any sponge city.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
Furthermore, it should be understood that although the present specification describes embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and it is to be understood that all embodiments may be combined as appropriate by one of ordinary skill in the art to form other embodiments as will be apparent to those of skill in the art from the description herein.
