Abstract
The invention discloses hot-welded geotechnical cloth. Belt-shaped polyethylene is arranged on one edge of a main cloth layer; and belt-shaped polyvinyl alcohol adhesive on the other opposite edge of the main cloth layer. In the construction site, the belt-shaped polyethylene and the belt-shaped polyvinyl alcohol adhesive of two pieces of geotechnical cloth are overlapped, and are thermally welded by a special tool to quickly and stably connect the two pieces of geotechnical cloth, so that the working efficiency in the construction site is improved; and the hot-welded geotechnical cloth is specifically suitable for a critical moment of flood fighting.
Description
Technical field
The present invention relates to a kind of geotextiles, particularly when needs bulk geotextiles, polylith geotextiles can be connected into fast an overall larger-size geotextiles.
Background technology
Geotextiles, also known as geotextile, be a kind of New Building Materials, raw material is the synthetic fibers of the high molecular polymers such as terylene, polypropylene fibre, acrylic fibers, polyamide fibre.It is by the water permeability geosynthetics of synthetic fibers by acupuncture or braiding.Finished product is cloth-like, is divided into according to manufacture method: Woven geofabric and non-woven geotextile two type.Common engineering mainly uses non-woven geotextile, and general width is 4-6 rice, and length is 50-100 rice.Geotextiles has outstanding filtration, draining, isolation, reinforcement, antiseepage, protective action, have lightweight, tensile strength is high, good penetrability, high temperature resistant, anti-freezing, ageing-resistant, corrosion-resistant.
Compared with the stone-laying of geotextiles and routine and concrete material anti-seepage effect, have investment low, construction technology is simple, and the duration is short, good seepage-proof property, channel effective utilization coefficients advantages of higher.
At present, geotextiles is mainly used in the little stressed large engineerings of silt diameter such as water conservancy, harbour, navigation channel, railway, highway, and its Main Function played comprises 1: buffer action, isolates the constructional materials of different physical properties, material is not mixed, keeps the globality of material; 2: filtration, when water flows into coarse fodder soil layer by fines soil layer, utilize the water permeability of geotextiles, allow water pass through and tackle the material such as soil particle, fine sand; 3: stabilization, strengthen soil body tension non-deformability, strengthen building structure stability.And existing conventional geotextiles is in the major works such as river levee, harbour, when usually needing larger sized geotextiles, the connective stability spread at the construction field (site) between the geotextiles that connects is low, an entirety effectively can not be formed between the two pieces of geotextiles be connected, and job site paving connects loses time, to fight flood and relieve victims etc., crucial moment delays construction speed, and when there is gap between two pieces of connected geotextiles, probably makes whole dykes and dams collapse.
Summary of the invention
The conveniently connection of geotextiles fast and stable at the construction field (site), the invention provides a kind of hot weld formula geotextiles, this hot weld formula geotextiles is provided with the structure facilitating two pieces of geotextiles to be connected at its edge, make can link together between two pieces of adjacent geotextiles fast and stable.
The technical solution adopted for the present invention to solve the technical problems is: an edge of the main cloth of hot weld formula geotextiles is provided with banded polyethylene, and another relative edge of main cloth is provided with banded polyvinyl alcohol glue.
A kind of prioritization scheme of such scheme is: the polyethylene of described band shape and the width of banded polyvinyl alcohol glue are five centimetres to 15 centimetres.
The invention has the beneficial effects as follows, owing to being respectively equipped with the polyethylene and polyvinyl alcohol glue that easily melt mutually under heat effect on two edges that hot weld formula geotextiles is relative, at the construction field (site) by superimposed for the polyvinyl alcohol glue of the polyethylene of the band shape of two pieces of geotextiles and band shape, then can rapidly and stably two pieces of geotextiles be connected with special instrument hot weld, improve job site operating efficiency, be particularly suitable for the crucial moment of fighting flood and relieve victims; Polyethylene and polyvinyl alcohol glue combine together under heat weldable effect, have corrosion-resistant, the characteristic such as high strength, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. main cloth, 2. polyethylene, 3. polyvinyl alcohol glue in figure.
Detailed description of the invention
In FIG, an edge of the main cloth 1 of hot weld formula geotextiles is provided with banded polyethylene 2, and another relative edge of main cloth 1 is provided with banded polyvinyl alcohol glue 3; The polyethylene 2 of described band shape and the width of banded polyvinyl alcohol glue 3 are ten centimetres.
Claims (2)
1. a hot weld formula geotextiles, is characterized in that: an edge of its main cloth is provided with banded polyethylene, and another relative edge of main cloth is provided with banded polyvinyl alcohol glue.
2. hot weld formula geotextiles according to claim 1, is characterized in that: the polyethylene of described band shape and the width of banded polyvinyl alcohol glue are five centimetres to 15 centimetres.
