Geotextile performance detection device for trapezoidal groove

Abstract

The invention relates to the field of geotextile, in particular to a geotextile performance detection device for a trapezoidal groove. The technical problem to be solved by the invention is to provide the geotextile performance detection device for the trapezoidal groove. The geotextile performance detection device for the trapezoidal groove is characterized by comprising a bottom frame, a laying unit, a tensile failure detection unit, a puncture resistance detection unit, a control screen, supporting columns, an anti-skid pad, a first support, a second support, a third support and a fourth support, wherein the bottom frame is connected with the laying unit; the bottom frame is connected with the puncture resistance detection unit; and the bottom frame is connected with the four sets of supporting columns. According to the geotextile performance detection device, the puncture resistance and tensile failure resistance of the trapezoidal groove geotextile are detected, the conditions of strong wind and heavy rain weather are simulated, and actual detection is fitted, so that the result credibility is high.

Description

technical field [0001] The invention relates to the field of geotextiles, in particular to a performance detection device for geotextiles used in trapezoidal trenches. Background technique [0002] Geotextile is a new type of building material. It is a geosynthetic material that exists between soil and pipes, gabions, or retaining walls to enhance water movement and hinder soil movement. As an interlayer material, geotextiles It needs to have the characteristics of high temperature resistance, high melting point, high tensile strength, good uniformity, strong adsorption and permeability, and strong chemical and biological resistance. [0003] At present, when the geotextile is laid and covered with sand, the geotextile is exposed. When it encounters strong wind and heavy rain, the geotextile will be blown in a wave shape, especially the geotextile laid on the trapezoidal groove. The gravel may be blown on the geotextile and rolled down. At this time, the geotextile needs to...

Problems solved by technology

[0003] At present, when the geotextile is laid and covered with sand, the geotextile is exposed. When it encounters strong wind and heavy rain, the geotextile will be blown in a wave shape, especially the geotextile laid on the trapezoidal groove. The gravel may be blown on the geotextile and rolled down. At this time, the geotextile needs to have good puncture resistance. In addition, rainwater will accumulate in the middle area of ​​the trapezoidal groove. At this time, the requirements for the tensile resistance of the geotextile are relatively high. Currently there is no such geotextile testing device
