Abstract

The invention discloses an unequal-thickness plastic tensile sheet and an earthwork standard room thereof. The forming method of the plastic tensile sheet of the earthwork standard room comprises the steps that a plastic sheet with a certain hole pattern is stretched after being heated to obtain tensile sheet billets with different thicknesses and specified sizes, and the tensile sheet billets are split or trimmed to obtain tensile sheet with different thicknesses and specific sizes of the earthwork standard room; the thickest part of the tensile sheet is fastened through a special fastener to obtain the plastic tensile sheet of the earthwork standard room. In this way, the plastic tensile sheet of the earthwork standard room is stable in structure and will not have strength loss caused by the fixation of the sheet of the earthwork standard room in the fastening process or in the using process of engineering.

Description

A kind of plastic tensile sheet material of not equal thickness and the geotechnical grid of this stretched sheet
Technical field
The present invention relates to a kind of plastic tensile sheet material of not equal thickness and the geotechnical grid of this stretched sheet
Background technology
At present plastic geocell is applied in limit slope nursing, and environmental protection greening, plants grass, and in the engineerings such as soft based process, its stretched sheet thickness is all uniformly, because the uniformity of thickness makes connection and the difficulty thereof of stretched sheet; Stretched sheet connect or the engineering application of geotechnical grid in, be not that damage stretched sheet declines its intensity, be exactly between stretched sheet, connect not compact or connect the insecure whole result of use that affects plastic geocell.
Summary of the invention
The object of the present invention is to provide a kind of plastic tensile sheet material of not equal thickness, in stretched sheet connection procedure, do not affect its intensity, obtain structure more stable, the plastic geocell of the higher and better effects if of fastening strength.
Object of the present invention is achieved through the following technical solutions: adopt the plastics orifice plate of special pass to obtain the not stretching blank with higher-strength of equal thickness through adding hot-stretch, then stretching blank is obtained to the not stretched sheet of equal thickness through cutting open or pruning; The thickness (the muscle portion not stretching) that the metal location of use special construction is fastened on this stretched sheet positions with fastening.
The connection location of stretched sheet is the ∪ sprig by securing member, two cover bolt and nuts and two
Figure BSA0000097518170000011
mutual combination between binding clip completes, and six faces that can fixed plastics stretched sheet junction are controlled the deformation range of plastic geocell effectively.
For improving the intensity of plastic geocell stretched sheet junction, the ∪ sprig of securing member of the present invention, bolt and nut and
Figure BSA0000097518170000012
type binding clip all adopts the metalwork with some strength, and bolt and nut is used national standard series of products, and nut adopts self-locking, and all metalworks all must carry out antirust processing or processing is moulded in plating, to improve the application life of plastic geocell.
For improving the locating effect of plastic geocell stretched sheet junction, the size of the ∪ sprig of securing member of the present invention,
Figure BSA0000097518170000013
size and the pitch-row of type anchorage clip plate hole, except noting cooperatively interacting, also should match with the relative dimensions of the plastic tensile sheet material of junction.
Compared to prior art, the invention has the advantages that: the uneven thickness of plastic tensile sheet material etc. but hot strength equate; The multi-disc plastic tensile sheet material that once can simultaneously stretch, the efficiency of producing plastic tensile sheet material improves greatly; Due to uneven thickness of plastic tensile sheet material etc., can do not lose stretched sheet intensity prerequisite under, by using special-purpose securing member that plastic tensile sheet material is linked together securely, obtain the plastic geocell of the more stable longer service life of structure.

The specific embodiment
Below in conjunction with Figure of description, content of the present invention is elaborated:
Be illustrated in figure 1 the plastic tensile sheet material that the invention provides a kind of not equal thickness, it comprises stretched portion and stretched portion (the thickest rib) not; Be illustrated in figure 3 the partial component schematic diagram of plastic geocell special fastener of the present invention, special fastener comprise two with holes
Figure BSA0000097518170000021
type binding clip, bolt and nut (nut is self-locking) and a ∪ sprig of two cover national standard series.
As shown in Figure 1 the plastic tensile sheet material of a kind of not equal thickness of the present invention be orifice plate by special pass through adding hot-stretch, then cut open or prune and form, it comprises stretched portion and stretched portion (the thickest rib) not.
The plastic geocell being formed by connecting through special fastener for the stretched sheet of a kind of not equal thickness of the present invention as illustrated in fig. 1 and 2, after it is rolled over by lattice chamber sheet material 4 dishes, in stretched sheet thickness, (muscle portion), through special fastener by adjacent sheet material 4 intervals, lattice chamber, is formed by connecting alternately; After geotechnical grid after connection stretches along stretching limit, two ends, the ground band between adjacent connection securing member forms single lattice chamber, makes integral body be cellular.
The plastic tensile sheet material of a kind of not equal thickness of the present invention and the geotechnical grid of this stretched sheet, described fastening be two cover bolts respectively near the edge at lattice chamber sheet material muscle portion two ends, ∪ sprig process
