以HDPE土工膜为核心材料的防渗结构广泛应用于国民经济各领域防渗工程,由于HDPE土工膜是一种柔性防渗材料,且在两个膜之间、膜与PE管道之间的焊接安装因同为PE;材质可达到较好的密封效果。但是一般在防渗边界,土工膜与刚性基础或墙壁,由于材料特性的差异,两者无法直接焊接安装,因此,现有的处理工艺如下:首先在刚性基础上设置基坑,然后将土工膜的末端牵引至基坑内,最后再向基坑内浇注混凝土,以解决防渗边界的密封问题。.上述处理方式对于长距离的防渗边界来说,施工时不仅耗费较多的工时,还会造成施工人员工作量的大幅增加,使得土工膜的铺设以及密封成本增加。
The anti-seepage structure with HDPE geomembrane as the core material is widely used in anti-seepage engineering in various fields of national economy. Because HDPE geomembrane is a kind of flexible anti-seepage material, and the welding and installation between the two membranes and between the membrane and PE pipe are PE; the material can achieve better sealing effect. But generally in the anti-seepage boundary, the geomembrane and rigid foundation or wall cannot be directly welded and installed due to the difference of material characteristics. Therefore, the existing treatment process is as follows: first, the foundation pit is set on the rigid foundation, then the end of the geomembrane is pulled into the foundation pit, and finally the concrete is poured into the foundation pit to solve the sealing problem of the anti-seepage boundary. . for the long-distance anti-seepage boundary, the above treatment method not only consumes more working hours, but also causes a significant increase in the workload of construction personnel, which increases the cost of laying and sealing geomembrane.

       在土工膜铺设完毕后防渗边界的处理工序相对麻烦,且耗费大量的人力物力,增加了土工膜在防渗工程中的铺设成本,对此,申请人直接摒弃传统的设置预埋基坑的方式，先将压条与所述土工膜的防渗边界齐平,然后利用膨胀螺栓依次贯穿土工膜、土工布后与刚性基础面连接,确保压条在刚性基础面上投影正对的土工膜紧贴在刚性基础面上,并且土工膜的上端部朝远离刚性基础面的方向翻折，直至将压条以及膨胀螺栓完全包裏后，再利用焊机将土工膜的翻折部分与其本体的外壁焊接,以防止在防渗边界附近的液体沿压条、土工布与膨胀螺栓之间的间隙进入到土工膜与刚性基础面之间,避免出现防渗边界的密封效果失效。
After the geomembrane is laid, the treatment process of the seepage control boundary is relatively troublesome, which consumes a lot of manpower and material resources, and increases the cost of geomembrane laying in the seepage control project. For this, the applicant directly abandons the traditional way of setting the embedded foundation pit, and first level the strip with the seepage control boundary of the geomembrane, Then, the expansion bolt is used to penetrate the geomembrane and geotextile in turn and connect them with the rigid foundation surface, so as to ensure that the geomembrane projected on the rigid foundation surface by the batten is close to the rigid foundation surface, And the upper end of the geomembrane is turned away from the rigid foundation surface until the bead and expansion bolt are completely wrapped, and then the welding machine is used to weld the turned part of the geomembrane and the outer wall of the geomembrane body, so as to prevent the liquid near the anti-seepage boundary from entering between the geomembrane and the rigid foundation surface along the gap between the bead, the geotextile and the expansion bolt, Avoid the failure of sealing effect of seepage control boundary.
