「雨水積磚」為一種將雨水在地下空間作一暫時性的保留，並將雨水有效的利用或抑制急速的流入河川。在水資源快速流失的區域，又無法建造大型水庫的地方，小型集水設施日漸重要，此設施的優點為1.耐壓強度高2.貯存的容積大3.搬運效率高4.儲存的效率高，另外可滋潤水土、還可有灌溉的功能，甚至還有與生態做結合使用或道路的水溝結合成小型防洪槽，廣泛的功能讓雨水積磚可最大化的使用水資源。
此設計主要是利用雨水積磚內部的空隙來達到儲水功能，利用每個雨水積磚層層堆疊成結構物形狀，然後將其埋藏於地底，利用管柱來支撐結構的重量，並探討管柱的形狀來最佳化結構的儲水率，同時又要兼顧結構的整體強度。此設施可以應用於生活周遭例如:操場、停車場、及其他空曠場所。
首先利用CAD軟體將雨水積磚建模，並且計算其儲水率及重量，將管柱中間部位內縮藉此提高雨水積磚內部孔隙，此外在內縮的部分加上肋條來維持結構的強度，包含4肋、8肋，接下來使用有限元素分析軟體ANSYS進行模擬，並透過靜態模組的分析，來觀察結構的強度，同時計算雨水積磚的儲水率，藉由兩者參數的影響下，來達到雨水積磚的優化設計，接著對結構進行模態分析以及地震分析討論，並且依照中央氣象局的地震標準，模擬實際情況進行模擬，以確保結構在受到地震波的影響時，是否有足夠的強度承受。
根據模擬的結果以及考量到模具設計的難易度及儲水率95%的考量下，以4肋的管柱設計最為理想，完成雨水積磚的修改與模擬後，再進行結構的其他元件設計，包含掛勾及外側的板子，利用這些元件將每個雨水積磚組裝成大型的結構。

Aqua-bricks are temporary storage facility and this design can slow down water into the sea efficiently. In storing up water difficult area, this type of storge facility is more important. The advantages of Aqua-Bricks are large storage, high storage efficiency, easy to transport, high structural strength. Aqua-Bricks could be used to irrigating and conservation of water and soil. In foreign, structures combined ecolgy with storage are common. The wide variety of function lead to maximize the water.
The design of Aqua-Bricks uses internal space to store water.Every Aqua-Bricks stacks each other layer by layer and would be buried in the ground. Aqua-Brick's tubes support the weight of the structure.This paper focuses on tube design to improve the storage efficiency.The objectives are improving the storage rate and strengthen the structural strength. This facility can be applied to the playground, parking and so on.
First, we constructed geometry and calculated storage efficiency of water and weight of Aqua-Bricks by using cad software. we designed to shrinking the diameter of the middle part of tube for improving storage efficiency. In addition, designing the ribs in skrinking part strengthens the structual strength. We simulated four ribs and eight ribs design.According to simulation results, the four ribs design are more closed to the purpose.Then, we discussed the results of modal analysis.It’s can avoid resonance frequency.Last, we researched the influence with earthquake in order to confirm the safety of design.
From the results, Aqua-Bricks’ storage efficiency reached to 95% and the weight of Aqua-Brick is 2.9Kg. This design can sustain 116200N weight. Every Aqua-Bricks is linked each other by hook.The board which dug hole in the surface is easy to osmsis for water. The board design is also very important in the paper.
