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

Embodiment 1

[0040] Embodiment 1 A laying process of geotextiles under a high pile wharf, comprising the following steps:

[0041] (1) Cutting: Geotextile 1 is made in two forms, one is the geotextile roll between odd-numbered racks; the other is the overlapping fabric roll between two adjacent geotextile rolls;

[0042] (2) Preliminary preparation: Roll out the geotextile on the ground, cut a round hole at the two steel piles at the row G and row B corresponding to the even pile position according to the drawing size, and then use two 20m long nylon Tie the two corners of one end of the geotextile roll firmly with the rope, and tie the other ends of the two nylon ropes to the cloth roll, and then turn the roll to roll the geotextile neatly on the roll;

[0043] (3) Positioning: Place the cloth rolling roller on the positioning buoy, drag the positioning buoy to the parking position at the front of the wharf, and after positioning the buoy, it is parallel to the parking barge. The parking ...

[0056] Embodiment 2 A laying process of geotextiles under a high pile wharf, comprising the following steps:

[0057] (1) Cutting: Geotextile 1 is made in two forms, one is the geotextile roll between odd-numbered racks; the other is the overlapping fabric roll between two adjacent geotextile rolls;

[0058] (2) Preliminary preparation: Roll out the geotextile on the ground, cut a round hole at the two steel piles at the row G and row B corresponding to the even pile position according to the drawing size, and then use two 20m long nylon Tie the two corners of one end of the geotextile roll firmly with the rope, and tie the other ends of the two nylon ropes to the cloth roll, and then turn the roll to roll the geotextile neatly on the roll;

[0059] (3) Positioning: Place the cloth rolling roller on the positioning buoy, drag the positioning buoy to the parking position at the front of the wharf, and after positioning the buoy, it is parallel to the parking barge. The parking ...

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...
