Gravity geotextile pipe mud grouting device

Abstract

The invention belongs to the technical field of lake ecological restoration equipment, and relates to a gravity geotextile pipe mud grouting device. The gravity geotextile pipe mud grouting device mainly comprises a mud bucket, a mud grouting box, a mud outlet, a geotextile pipe guide groove and a geotextile pipe gripper, wherein the mud bucket is arranged above and vertically communicated with the mud grouting box; an opening on one side of the mud grouting box is connected with the mud outlet; the mud grouting box is a piston type pressurizable box body; the geotextile pipe guide groove is formed below the mud outlet; and the geotextile pipe gripper is arranged at an intersection of a position under the mud grouting box and the uppermost end of the geotextile pipe guide groove. The device has a reasonable design, is convenient to operate and has the advantage that the movement capacity is not limited in a lake; and when a geotextile pipe which is subjected to mud grouting by the mud grouting device is put in a littoral zone of the lake or a river, a hydrodynamic structure can be improved, littoral wind waves are reduced, silt lodging is accelerated, a littoral base is stabilized, and conditions are created for restoring aquatic vegetations in the littoral zone, particularly in a hard revetment lakeside zone.

Description

technical field [0001] The invention belongs to the technical field of lake ecological restoration equipment and relates to a gravity geotechnical pipe grouting device. Background technique [0002] At present, when the ecological restoration of lakes is carried out for bank revetment and anti-corrosion, an existing technology commonly used is underwater geotechnical pipe technology. Geotechnical pipes made of geotextiles are placed at the front of the lakeside beach to isolate and block water flow and wind and waves on the beach. Direct flushing action. When filling mud into the geotechnical pipe, the commonly used grouting device in the prior art is to use a motor to drive the mud filling box, and the mud is sucked from the mud bucket into the mud filling box, and then the mud is pushed and pressed. Squeeze to the mud outlet pipe and flow into the soil cloth pipe. The mud filling box of the equipment is directly connected with the inlet and outlet pipes. During operation,...

Problems solved by technology

However, the production cost of this grouting device is still high, and it cannot meet the requirements that the grouting operation in lake ecological restoration is simple and fast, and can be operated on the water surface

[0005] The geotechnical pipes that are used in conjunction with the grouting device in the prior art are basically geotechnical bags made of single-layer geotextiles, and holes are left on the geotechnical bags at intervals to discharge the muddy water through high pressure. Fill the bag into the bag at the same time through multiple holes, and at the same time bring the geotechnical bag with small holes and gaps, and form a geotechnical tube after the water is discharged; this kind of perfusion of a section of the pipeline is not continuous, and the geotechnical bag of this structure is filling After the soil is applied, due to the immersion below the water surface, the soil is easily washed out from the geotechnical bag due to the erosion of wind and waves, which affects the function of the geotechnical pipe bank revetment

Moreover, the commonly used geotechnical pipes are generally arranged linearly on the embankment, and the protection force for the embankment is relatively weak.

The geotechnical pipes in the prior art are only used in the base restoration of lakes, and there are no reports on the application of stabilizing lake bases and accelerating sediment settlement.
