Abstract

The invention discloses a dredged mud storage yard multi-dimensional gas-ejecting anti-clogging integrated synthetic drainage system. Through anti-silting-clogging drainage boards (6) arranged at a mud discharging field in a matrix mode in advance depending on horizontal positioning pulling ropes (4), a multi-dimensional and stereoscopic drainage system is established, and through a water-gas integrated pumping and drainage device (13), moisture in a storage yard is discharged; and the circulating speed of air in a soil body is accelerated, and dehydration and desiccation of the soil body areaccelerated. Through a high-pressure gas jet device (12), high-pressure gas is ejected, and fine particles clogged on the drainage system are discharged; and rapid drainage and desiccation of dredgedmud are improved, the occupied area and occupying time of the dredged mud storage yard are effectively reduced, and the dredged mud storage yard multi-dimensional gas-ejecting anti-clogging integratedsynthetic drainage system has the advantages of low engineering cost, good anti-clogging effect, high drainage efficiency and simple and convenient operation.

Description

technical field [0001] The present invention belongs to IPC classification E02D3 / 10 drainage basic engineering technology, or rapid drying treatment technology for river and lake dredging and mud discharge field of water conservancy projects, and also relates to high-pressure air jet flow anti-silting technology and related device working principle and application scene description. Especially the multi-dimensional air injection anti-clogging integrated comprehensive drainage system for dredged mud yards. Background technique [0002] Many rivers, reservoirs, lakes and irrigation canals have different degrees of sedimentation, especially in the downstream reaches and river estuaries. There is generally a large amount of sedimentation, and dredging projects are needed to restore their water flow, water regulation, flood control and navigation. function. For example, the water area of ​​Dongting Lake has shrunk significantly in recent years. It is due to soil erosion in the u...
