Transverse drainage type composite geomembrane and transverse drainage method
The invention provides a transverse drainage type composite geomembrane and a transverse drainage method. The transverse drainage type composite geomembrane comprises an impermeable layer, geotechnical cloth and a plurality of drainage belts arranged on the impermeable layer at intervals. The drainage belts are provided with drainage channels which extend in parallel in the longitudinal direction and are densely arranged, and a drainage groove capable of achieving directional drainage is defined by every two adjacent drainage belts and the impermeable layer between the two drainage belts; the geotechnical cloth is tightly attached to the top faces of the drainage belts and the impermeable layer. The composite geomembrane provided by the invention can prevent water from permeating into a roadbed downwards, a roadbed transverse drainage channel is added under the condition that roadbed soil particles are not taken away by drainage, roadbed drainage is facilitated, the problem caused by an unsmooth drainage part of an existing roadbed is effectively solved, and the service long-term effect of the roadbed is improved; the drainage belt is used for preventing water from longitudinally moving towards the roadbed along the surface of the impermeable layer, so that the retention time of the water in the roadbed is effectively shortened, and roadbed maintenance is facilitated.
本发明提供了一种横向排水型复合土工膜及横向排水方法。横向排水型复合土工膜包括：防渗层、土工布和间隔设置在防渗层上的多个排水带；排水带为具有沿纵向平行延伸且密集排布的排水通道，相邻的两个排水带与两个排水带之间的防渗层围合形成可定向排水的排水沟槽；土工布紧密贴合在多个排水带和防渗层的顶面上。本发明提供的复合土工膜可防止水向下渗入路基，在保证排水不带走路基土体颗粒的情况下增加路基横向排水通道，有利于路基排水，有效解决现有路基排水部不畅导致的问题，提高路基服役长效性；利用排水带阻挡水沿防渗层的表面向路基的纵向移动，从而有效减少水在路基内的停留时间，有利于路基养护。
