Dewatering well and construction method thereof
The invention provides a dewatering well and a construction method thereof. The dewatering well comprises a well pipe and a plurality of water filtering layers, the well pipe is arranged in a well pit, and the well pipe comprises a water filtering pipe provided with a plurality of water permeable holes; the multiple water filtering layers are sequentially arranged on the outer side of the water filtering pipe from inside to outside in the radial direction of the water filtering pipe, each water filtering layer comprises a filtering material layer, the particle sizes of filtering materials of the multiple filtering material layers are gradually increased from inside to outside in the radial direction of the water filtering pipe, and the grading of the multiple filtering material layers is different. According to the dewatering well structure, underground water in the well pipe of the dewatering well can be effectively filtered, silt is prevented from blocking the filter material and the water filter pipe as much as possible, and therefore the good silting prevention effect is achieved.
本发明提供一种降水井及其施工方法。所述降水井包括：井管和多层滤水层，所述井管设置在井坑内，所述井管包括设置有若干透水孔的滤水管；多层所述滤水层沿所述滤水管的径向从内向外依次布置在所述滤水管的外侧，所述滤水层包括滤料层，沿所述滤水管的径向从内向外，多层所述滤料层之滤料的粒径逐渐增大，且多层所述滤料层的级配不同。本发明的降水井结构，能够对降水井井管内的地下水进行有效的过滤，尽可能地防止泥沙堵塞滤料和滤水管，从而起到较好的防淤塞作用。
