Abstract
This utility model relates to a kind of two-layer compound GSZ.This two-layer compound GSZ is made up of the HDPE geomembrane of bilayer longitudinal direction grid rib tape, double-deck laterally grid rib tape, double-deck oblique grid rib tape and centre, lap-joint in each two grid rib tape is respectively provided with position, a hole, by screw rod through position, hole, the HDPE geomembrane of double-deck GSZ with centre is bolted together with.
Description
Technical field
This utility model relates to a kind of two-layer compound GSZ, and with double-deck GSZ, HDPE geomembrane is compounded in one
Rise, it is possible to strengthen resistance to compression effect and anti-seepage effect, be particularly suited for dam reinforcement, Retaining Wall Engineering.
Background technology
At present, most widely used GSZ is mostly formed with the stretching of horizontal grid rib tape by longitudinal grid rib tape
Tetragon network structure, can play certain reinforcement effect to soil body engineering.But, due to domestic GSZ performance rule
Lattice are more single, and compressive property is poor, it is impossible to fix the sand antiseepage, it is impossible to meet the needs of multiple reinforcing engineering.
Utility model content
This utility model is a kind of two-layer compound GSZ, double-deck longitudinal grid rib tape, double-deck laterally grid rib tape, double
The oblique grid rib tape of layer and middle HDPE geomembrane composition, the lap-joint in each two grid rib tape is respectively provided with position, a hole,
By screw rod through position, hole, the HDPE geomembrane of double-deck GSZ with centre is bolted together with.
As improvement, each two grid rib tape lap-joint on double-deck GSZ is respectively provided with position, a hole, is worn by screw rod
Cross this position, hole, double-deck GSZ is bolted together with HDPE geomembrane.
As improvement, HDPE geomembrane is placed between double-deck GSZ by this utility model, and HDPE geomembrane thickness is
1.5 ~ 2mm, double-deck GSZ thickness is 6 ~ 8mm, and grid rib tape width is 20 ~ 25mm.
As improvement, this utility model is by bilayer longitudinal direction grid rib tape (3), double-deck laterally grid rib tape (4), Double-layer oblique
The triangular mesh structure being drawn into grid rib tape (5).
The beneficial effects of the utility model are: arrange HDPE geomembrane in the middle of this utility model, and advantage is soft as one
Property waterproof material, has the highest antiseepage coefficient；There is good chemical stability, be resistant to strong acid, alkali, the corrosion of oil, be
Good anti-corrosion material.It is provided with and is drawn into by bilayer longitudinal direction grid rib tape, double-deck laterally grid rib tape, double-deck oblique grid rib tape
Triangular mesh structure, it is possible to strengthening its resistance to compression effect, consolidation effect strengthens.

Detailed description of the invention
With reference to the accompanying drawings 1, HDPE geomembrane (1), double-deck longitudinal grid rib tape (3), double-deck laterally grid rib tape (4), double-deck
Oblique grid rib tape (5), bolt head (6) forms the elementary cell of this invention.Before use, HDPE geomembrane (1) is placed on
In the middle of double-deck GSZ (2), the lap-joint in each two grid rib tape is respectively provided with position, a hole, by both sides bilayer GSZ
Position, hole alignment, screw rod (8) pass position, hole, bilayer GSZ and HDPE geomembrane are bolted together.Using
Time, two-layer compound GSZ is placed on dykes and dams, it is possible to prevent sandy soil and water from flowing out this two-layer compound GSZ, play very
Good antiseepage effect, increases two-layer compound GSZ anti-pressure ability.The laying step of two-layer compound GSZ is with common
The laying step of GSZ is identical, and back fill course carries out mechanical ramming after exceeding 2 ~ 3 times of grid rib tape height.
