This invention relates to the field of membrane laying technology, and more particularly to a geomembrane laying device. It includes a frame with two sets of rollers symmetrically arranged on it. These rollers work together to support the geomembrane roll. A base plate is detachably mounted at both ends of the geomembrane roll on the frame. A primary spring is mounted on the base plate, with a truss plate above it. A secondary spring is mounted on the truss plate, and a support is mounted above the secondary spring. A horizontal insert is detachably mounted on the support, with a rod inserted into the insert. A top spring is positioned between the rod and the insert. This multi-stage buffer structure, combining primary and secondary springs, along with the top spring, achieves graded dispersion of elastic tension, significantly reducing the geomembrane pinching and tensile damage problems caused by the concentrated tension of traditional single-segment springs, thus ensuring the geomembrane's impermeability and service life.
