Laying process of geotechnical cloth under high-pile wharf

Abstract

The invention provides a laying process of geotechnical cloth under a high-pile wharf. The laying process of the geotechnical cloth under the high-pile wharf is characterized by comprising the following steps of (1) clipping; (2) preparing previously; (3) positioning; (4) laying a geotechnical cloth roll; and (5) laying a lap-joint cloth roll. According to the laying process of the geotechnical cloth under the high-pile wharf provided by the invention, the sequence of pile sinking and geotechnical cloth laying is adjusted, and the geotechnical cloth under the wharf is laid after pile sinking is accomplished, so that the defects are effectively overcome; and in addition, in the process, sandbags press when the geotechnical cloth roll and the lap-joint cloth roll are laid at the same time, so that the geotechnical cloth is laid flatly and not easy to move, and a laying effect is better.

Description

technical field [0001] The invention relates to the technical field of geotextile laying, in particular to a geotextile laying process under a high-pile wharf. Background technique [0002] At present, the laying of geotextiles under the high-pile wharf is mostly done during dredging and slope repair, and then the pile sinking and riprap construction are carried out, but this laying method has the following defects: (1) The working surface required for the pile sinking operation ship on the water Large, the pile driving operation is restricted by the laying speed of the geotextile, and the pile sinking operation can only be carried out after the laying of the geotextile along the bank slope is 150-200 meters wide; (2) The time interval between the completion of the laying of the geotextile and the riprap ballast After the pile is completed), the geotextile is washed away by the seabed water flow, and the geotextile above the water surface on the shore is exposed to the sun f...

Problems solved by technology

[0002] At present, the laying of geotextiles under the high-pile wharf is mostly done during dredging and slope repair, and then the pile sinking and riprap construction are carried out, but this laying method has the following defects: (1) The working surface required for the pile sinking operation ship on the water Large, the pile driving operation is restricted by the laying speed of the geotextile, and the pile sinking operation can only be carried out after the laying of the geotextile along the bank slope is 150-200 meters wide; (2) The time interval between the completion of the laying of the geotextile and the riprap ballast After the pile is completed), the geotextile is washed away by the seabed water flow, and the geotextile above the water surface on the shore is exposed to the sun for a long time, and it is easy to age; (3) when sinking the pile, the pile tip can only sink into the mud surface after penetrating the geotextile In this process, the geotextile is prone to slide, tear, etc.; (4) when the pile is sinking, when the pile position is just on the bagged gravel or other pressing stone materials, the pile position is prone to deviation; so It is urgent to study a new technology of laying geotextiles to solve the above problems
