Embodiment Construction

[0020] A rapid drainage PVA drainage system for silt yard, its overall structure includes 4 parts: hollow main pipe, double-layer water-absorbing pad, fixing pin, and vacuum pump joint.

[0021] The hollow main pipe 1) in the structure is a hollow round pipe integrally formed by PVA material, which can be overlapped by latitude and longitude to form the vertical and horizontal main channel of the drainage system. The moisture in the hollow main pipe 1) is sucked into the hollow main pipe 1), and the two ends of the hollow main pipe 1) are connected to the vacuum pump connector 4), and the vacuum suction is provided by the vacuum pump to discharge the moisture in the hollow main pipe 1);

[0022] The double-layer water-absorbing pad 2) in the structure is a mattress-type water-absorbing material made of PVA material. The upper and lower layers cover the hollow main pipe 1), and are fixed together with the hollow main pipe 1) by fixing pins 3). Pad 2) is in direct contact with h...

Abstract

The invention provides a PVA drainage system for rapid drainage of a sludge storage yard and a using method thereof. The PVA drainage system is composed of hollow main pipes, double-layer water absorption pads, fixing pins and vacuum pump joints. The PVA drainage system is used in a fast drainage project of a high-water-content sludge pile field and is laid in a storage yard, and the water in thesludge can be quickly discharged by utilizing the capillary water absorption effect of the water, is collected in a main pipeline and is drawn out through a vacuum pump. According to the drainage system and the using method thereof, the problem of blockage of a drainage body in a conventional vacuum drainage project can be avoided, the drainage process can be carried out, and meanwhile, the capillary action of the water is utilized to absorb water and drain water; the vacuum pump is started intermittently, so that a large amount of energy consumption is saved, and the green energy-saving effect is achieved; and PVA materials belong to degradable materials and are not required to be disassembled after drainage construction is finished and can be automatically degraded in the soil body, so that the influence on the environment is small.

Description

technical field [0001] The invention relates to a rapid drainage PVA drainage system for a sludge stockyard and its application method. The rapid drainage system is used in the drainage consolidation project of dredging a sludge stockyard with a high water content, especially in the working condition where the fine particle content of the sludge is high Next, using the excellent capillary water absorption characteristics of the PVA material, using its own suction to absorb the water in the sludge into the drainage body, and then pumping out the water in the drainage body through an external vacuum pump, this drainage system can be left behind after the construction is completed. In the soil, it will gradually degrade over time, causing minimal environmental pollution. At the same time, the drainage body mainly uses capillary suction to absorb water, and the external vacuum pump does not need to be started all the time, but only needs to be turned on intermittently, which saves...
