[0005] Technical problem: The purpose of this invention is to provide a U-shaped low-vacuum dredging sludge rapid drainage method, aiming at the problems of large amount of low-concentration dredging sludge, high water content, slow natural drainage, and long consolidation time of sedimentation and drainage. A U-shaped drainage system is pre-set up in the sludge storage yard, and a low vacuum negative pressure is applied to the drainage system to quickly discharge the moisture in the sludge, so as to quickly discharge the moisture in the sludge with high water content. The purpose of greatly increasing the silt concentration in the storage yard

Embodiment Construction
[0020] 1. Structure space drainage system:
[0021] (1) Processing materials: perforate the PVC pipe, form the water filter pipe 3 to the PVC pipe 1 coat layer geotextile 2 after the perforation, process the U-shaped sand bag 4 and the wood pile (or moso bamboo) 5, the U-shaped sand bag is provided with Processed water filter pipes, and at the same time do a good job of cutting off various drain pipes;
[0022] (2) Erection of U-shaped sandbags: Move the prepared U-shaped sandbags into the cofferdam 6, the two ends of the U-shaped sandbags are arranged along the length of the yard, and the horizontal and vertical spacing of the U-shaped sandbags depends on the situation , use wooden stakes (or bamboo) to fix the two ends of the U-shaped sand bag vertically, and the depth of the wooden stake (or bamboo) driven into the mud should ensure that the sand bag will not be washed down by the silt during the silt blowing process;
[0023] (3) Set up a vacuum device and a ventilation d...

A U-shaped low vacuum dredging sludge rapid drainage method relates to a method which rapidly deals with the drainage of low concentration dredging sludge generated in the engineering construction ofwater conservancy, harbor approach, and substantially increases the concentration of the dredging sludge in the sludge stockyard. A U-shaped drainage system is formed by erecting a U-shaped sand bag in advance in a closing dam. The two ends of the U-shaped sand bag are respectively connected with an evacuating device and a venting device with a venting valve to form a space drainage system. In order to prevent clogging, when water is pumped, the venting valve is regulated to cause the drainage system to pump water in the low vacuum. During the pumping process, the venting valve is regulated according to the water content of the sludge in the closing dam; the vacuum pressure in the drainage system is gradually increased to guarantee the drainage efficiency of the system. The invention has simple technique and low cost, and is suitable for the large area of stockyard disposal project in the low concentration dredging sludge.
Description
technical field [0001] The present invention is a method for quickly draining low-concentration dredged silt produced in the construction of water conservancy and port waterway projects and greatly increasing the concentration of dredged silt in the silt storage yard, and is suitable for large-area storage yard disposal projects for low-concentration dredged silt. It belongs to the technical field of water conservancy and port channel engineering. Background technique [0002] my country's rapid economic development has brought about a climax in the construction of water conservancy and port waterway projects. During the dredging and widening of various rivers and waterways, as well as in the construction and expansion of ports, a large amount of discarded dredging silt will inevitably be produced. According to incomplete statistics, the discarded dredged silt in my country reaches 100 million m3 every year. 3 Above: A considerable amount of dredging silt has been produced ...
