Adjustable sand barrier
The invention relates to the technical field of sand blocking equipment, and discloses an adjustable sand barrier which comprises a stand column structure and a sand barrier structure, the stand column structure is connected with the sand barrier structure, the stand column structure comprises a base, the base is in a prismatic table shape with the horizontal section area gradually reduced from bottom to top, and a telescopic stand column is fixedly embedded in the base; the sand barrier structure comprises a variable-porosity sand barrier and a support used for supporting the variable-porosity sand barrier, the porosity of the lower portion of the variable-porosity sand barrier is smaller than that of the upper portion of the variable-porosity sand barrier, and the porosity of the middle of the variable-porosity sand barrier is gradually increased from bottom to top. The tensile stress of the sand barrier is reduced, the sand barrier can be effectively avoided, the sand accumulation pressure on the sand barrier is reduced, the sand barrier toppling is reduced, and the sand blocking efficiency of the sand barrier is improved.
本发明涉及阻沙设备技术领域，公开了一种可调节沙障，包括立柱结构和沙障结构，所述立柱结构与所述沙障结构连接，所述立柱结构包括底座，所述底座呈水平截面面积由下往上逐渐减小的棱台型，所述底座上固定嵌设有伸缩立柱；所述沙障结构包括变孔隙率沙障和用于支撑所述变孔隙率沙障的支架，所述变孔隙率沙障的下部的孔隙率小于上部的孔隙率，且所述变孔隙率沙障的中部的孔隙率由下往上逐渐增大；本发明减小沙障拉伸应力，可有效避免沙障，降低沙障受积沙压力，减少沙障倾倒，提高沙障阻沙效率。
