Drain board built-in geotube device for sludge dehydration

Abstract

The invention discloses a drain board built-in geotube device for sludge dehydration. The drain board built-in geotube device comprises a geotube for filling sludge; the geotube is internally providedwith a plurality of drain boards in a length direction of the geotube; the end, located on the geotube, of each of the plurality of drain boards is connected with the water inlet end of one of drainboard connectors; and the water outlet end of each of the drain board connectors is connected with a vacuum pump connected to the outer part of the geotube and used for pumping water of the sludge filled in the geotube by using a vacuum pipe inserted into the geotube. The drain board built-in geotube device is of a vacuum board built-in geotube structure, the vacuum pipe is pre-buried into the geotube according to a certain way, and a vacuum load is applied by the external vacuum pump by virtue of the vacuum pipe and the drain boards after the sludge is filled, so that the dehydration of the sludge in the geotube can be rapidly realized, the on-site construction efficiency is effectively increased, large-scale engineering application is easy to realize, and the drain board built-in geotubedevice has great engineering significance and application prospect.

Description

technical field [0001] The invention relates to a device for treating sludge in industrial buildings and water conservancy projects. In particular, it relates to a geotechnical tube bag device with a built-in drainage board for sludge dewatering. Background technique [0002] Sludge includes semi-solid or solid substances (industrial sludge) with different moisture content produced during sewage treatment; or sludge produced by urban rivers, lake dredging and dredging projects and urban sewers (dredging sludge); or produced by wet methods The fine-grained waste (tailings sludge) produced by mineral processing. Due to the rapid development of urbanization in my country, the amount of sludge produced is increasing year by year. According to relevant literature, in 2014 my country's urban industrial sludge production was about 28.0147 million tons, a year-on-year increase of 11.57%. The total volume of dredged silt in water conservancy projects exceeds 100 million cubic mete...

Problems solved by technology

Therefore, the requirements for the material strength of the lower tube bag are increased, which increases the cost of engineering materials

In addition, in the stacking method, the lower tube bag is pressed flat and cannot be refilled, and the performance of the material has not been fully utilized.
